Porifera is a unique system for cooling powerleds
and other electronic components through aluminium
foam . The unique properties of this aluminium
foam allow for a much higher cooling performance
compared to conventional cooling bodies . LED
light fixtures that make use of Porifera technology
have greater efficiency, made possible through the
following characteristics :
• Large cooling surface : the foam has an extremely high
surface aspect ratio thus creating a large surface within
a small volume. The larger the cooling surface, the more
heat can be dissipated.
• Low mass per volume : the aluminium foam is very
thin which brings the great advantage that the heat is
transferred immediately to the environment (air) and is
not first stored in the material itself like in conventional
systems. Such traditional systems have a radiator effect
i.e. the material fully heats up and only then interacts
with its environment. So the thicker the material, the
slower it cools down. The low mass per volume of
Porifera results in a low heat capacity. It reacts almost
instantly to temperature changes which results in very
short transient regimes, making it a very controllable
heat exchanger.
• Porous : the open cell structure allows for a free flow
of air through the mazes of the foam thus securing an
optimal heat exchange with the environment.
• Isotropic : the interconnected bubbles form a convoluted
path for any gases or liquids flowing through them.
Such a complex path continually brings the gases into
contact with the metal walls. This results in outstanding
convective heat transfers. An additional advantage of
this isotropic structure is that heat is distributed evenly
in a three-dimensional manner, so the performance is
independent of the direction of the convective flow.
Cooling LED fixtures with Porifera is much more efficient
than cooling with conventional cooling elements thus
providing increased life span as well as improved efficiency.
An LED’s life span and its efficiency are directly correlated
with its junction temperature. This correlation follows
3

an exponential line i.e. more efficient cooling has an
enormous impact on these factors.
Specifications of Porifera :
• Open cell structure
• Organic structure
• Isotropic
• Aluminium
Porifera is a passive cooling system that brings all the
advantages of an active cooling system without the
downsides : greater efficiency without the need for
maintenance and completely noiseless.
Advantages :
• Longer LED life span
• Improved LED efficiency
• Lower power consumption
• Completely maintenance free
• Noiseless

Porifera is een uniek systeem om vermogenleds
en andere elektronische componenten te koelen
door middel van opgeschuimd aluminium . Door de
unieke eigenschappen van dit aluminium schuim
wordt een veel hogere koelcapaciteit bereikt dan
mogelijk is met conventionele koellichamen . De
grotere efficiëntie van een ledtoestel met Porifera
technologie wordt mogelijk gemaakt door de
volgende factoren:
• Groot koeloppervlak : het schuim heeft een extreem
hoge oppervlakte aspect ratio. Hierdoor wordt een
grote oppervlakte bekomen binnen een klein volume.
Hoe groter de koeloppervlakte, hoe meer warmte er
afgevoerd kan worden.
• Lage massa per volume : de wanddikte van het
aluminiumschuim is enorm dun. Dit heeft als groot
voordeel dat de warmte onmiddellijk wordt afgegeven
aan de omgeving (lucht) en niet eerst wordt opgeslagen
in het materiaal zelf, zoals bij een klassiek systeem. Bij
klassieke systemen spreken we van het radiatoreffect;
het materiaal warmt eerst volledig op en komt dan
in interactie met zijn omgeving. Dus hoe dikker de
wanddikte, hoe minder snel iets wordt afgekoeld.
Door de lage massa per volume bezit Porifera een
lage warmtecapaciteit; hierdoor reageert het bijna
onmiddellijk op temperatuursveranderingen, waardoor
de aanpassingstijd erg kort is.
• Poreus : door de open cel structuur kan omgevingslucht
in al de mazen van het schuim vrij bewegen, waardoor
de warmtewisseling met de omgeving maximaal
verloopt.
• Isotroop : de met elkaar verbonden bellen vormen
een onwillekeurig pad voor ieder gas dat erdoor
vloeit. Dit complexe pad brengt voortdurend het gas
in contact met de metalen wand. Dit resulteert in een
extreem grote convectieve warmteoverdracht. Een
bijkomend voordeel van de isotrope structuur is dat de
warmteoverdracht in 3D verloopt, waardoor de werking
onafhankelijk is van de orientatie.
Met Porifera wordt een ledtoestel veel efficiënter gekoeld
4
2012 • 01
dan met klassieke koelelementen, waardoor de levensduur
van de leds verlengd wordt en het rendement van de leds,
met name de hoeveelheid licht, veel hoger wordt.
De efficiëntie en de levensduur van de leds staan in
correlatie met de junctie-temperatuur van de leds.
Deze correlatie volgt een exponentiële lijn, m.a.w. een
efficiëntere koeling heeft een enorme impact op zowel de
levensduur als het rendement van de led.
Specificaties van Porifera :
• Open cel structuur
• Organische structuur
• Isotroop
• Aluminium
Porifera is een passief koelsysteem met alle voordelen
van een actief systeem, nl. grotere efficiëntie, zonder de
nadelen ervan. Er is absoluut geen onderhoud nodig,
er kan niets stuk gaan en het systeem werkt volledig
geruisloos.
Voordelen :
• Langere levensduur van de leds
• Meer lichtopbrengst van de leds
• Lager elektriciteitsverbruik
• Volledig onderhoudsvrij
• Geruisloos

Porifera est un système unique pour refroidir les LED
de puissance et les autres composants électroniques
grâce à la mousse d’aluminium . De part ses propriétés
uniques, la mousse d’aluminium possède une capacité
de refroidissement beaucoup plus importante et
aussi beaucoup plus rapide que les refroidisseurs
traditionnels .
L’efficacité accrue d’un appareil led avec le système
Porifera est visible à travers les facteurs suivants:
• Une grande surface de refroidissement: le ratio entre le
volume et la surface de mousse est extrêmement grand.
Même dans un volume restreint, la surface de dissipation
de la chaleur est extrêmement élevée. Plus la surface
de refroidissement est grande, plus la chaleur se dissipe
rapidement.
• Une densité faible : l’épaisseur de la mousse d’aluminium
est très mince. Ceci a le grand avantage que la chaleur
est directement en contact avec l’air ambiant et n’est
donc pas d’abord stockée dans le matériau lui-même,
comme dans un système classique. Dans les systèmes
classiques, on parle même de l’effet « radiateur ».
Le matériau emmagasine d’abord la chaleur puis la
disperse dans l’air. Plus les parois du refroidisseur sont
épaisses, plus celui-ci met de temps à évacuer la chaleur.
La faible densité rend l’inertie thermique du Porifera
extrêmement faible, ce qui lui permet de réagir presque
instantanément aux changements de température.
• Porosité : la structure de la mousse avec ses cellules
ouvertes permet une circulation optimale de l’air dans
toute la masse de l’aluminium, l’échange de chaleur
avec l’environnement est optimal.
• Isotropie : Les bulles forment un réseau de chemins que
l’air traverse. Dans ce parcours l’air est constamment
en contact avec la surface du métal. Il en résulte un
transfert de chaleur par convection extrêmement
important.
Un avantage supplémentaire de la structure de cette
mousse est quel est isotrope. Le transfert de chaleur est
indépendant de l’orientation.

Un appareil LED équipé du système PORIFERA a un
pouvoir de refroidissement élevé et prolonge la durée de
vie ainsi que l’émission de lumière au niveau qualitatif et
quantitatif.
L’efficacité et la durée de vie des Leds sont en corrélation
avec leur température de jonction. Ce rapport suit une
ligne exponentielle. Un refroidissement efficace a donc
un impact énorme sur la durée de vie et le rendement des
leds.
Caractéristique du Porifera :
• Structure à cellules ouvertes

Porifera est un système de refroidissement passif avec tous
les avantages d’un système actif, tels que l’efficacité plus
grande, sans ses inconvénients, il ne nécessite absolument
aucun entretien, rien ne peut se défaire et le système est

Porifera ist ein einzigartiges System für die Kühlung
von Power-LEDs und anderen elektronischen
Komponenten durch geschäumtes Aluminium . Durch
die einzigartigen Eigenschaften des Aluminium-
Schaumes wird eine viel höhere Abkühlkapazität als
mit herkömmlichen Kühlkörpern erreicht . Die höhere
Effizienz einer LED Leuchte, die über die Porifera
Technologie verfügt, wird möglich durch folgenden
Faktoren:
• Große Kühlfläche: Der Schaum hat eine extrem hohe
Oberfläche. Aspekt Verhältnis: hier ist eine große
Oberfläche bei kleinem Volumen vorhanden. Je größer
die Kühlfläche, desto mehr Wärme abgeführt werden
kann.
• Geringe Masse pro Volumen: Die Wanddicke des
Aluminium-Schaumes ist sehr dünn. Dies hat den
Vorteil, dass die Wärme direkt an die Umgebung (an
die Luft) abgegeben werden kann und nicht zuerst
im Material selbst gespeichert wird, wie in einem
klassischen Kühlsystem. In herkömmlichen Systemen,
sprechen wir von dem Heizkörper-Effekt: das Material
erhitzt sich zuerst komplett selbst und interagiert
dann mit der Umgebung. Je dicker die Wanddicke, je
langsamer erfolgt die Abkühlung. Durch die geringe
Masse pro Volumen hat die Porifera eine geringe
Wärmekapazität, deshalb reagiert sie fast augenblicklich
auf Temperaturänderungen, wodurch die Zeiteinstellung
der Anpassung bzw. Abkühlung sehr kurz ist.
• Poröse Struktur: Durch die offene Zellstruktur kann
die Umgebungsluft sich in alle Löcher des Schaumes
frei bewegen, wodurch der Wärmeaustausch mit der
Umgebung maximal ist.
• Isotrop: Die miteinander in Verbindung stehenden
Luftblasen bilden einen vorgegebenen Weg, wodurch
das Gas (in diesem Fall Luft oder O2) fließt. Dieser
komplexe Weg bringt ständig das Gas in Kontakt mit
dem Metall der Wand. Dies führt zu einem extrem
hohen konvektiven Wärmeübergang. Ein weiterer Vorteil
der isotropen Struktur ist, dass die Wärmeübertragung
sich dreidimensional entwickelt, so dass der Effekt
unabhängig von der Ausrichtung ist.

Mit Porifera wird eine LED Leuchte viel effizienter gekühlt,
wodurch die Lebensdauer der LEDs und damit die Effizienz
der LEDs in Bezug auf die Lichtmenge erhöht wird.
Der Wirkungsgrad und die Lebensdauer der LEDs stehen in
Korrelation mit der Sperrschichttemperatur der LEDs.
Diese Korrelation folgt einer exponentiellen Linie, das
heißt, eine effizientere Kühlung hat einen großen Einfluss
sowohl auf die Lebensdauer und auf die Effizienz der LED.
Technische Daten Porifera:
• Offene Zellsstruktur
• Organische Struktur
• Isotrop
• Aluminium
Porifera ist ein passives Kühlsystem mit allen Vorteilen
eines aktiven Systems, nämlich mehr Effizienz, ohne die
Nachteile, eine Wartung ist nicht erforderlich, sie kann

Vorteile :
• Längere Lebensdauer der LEDs
• Mehr Lichtausbeute der LEDs
• Geringerer Stromverbrauch

Porifera es un sistema único de refrigeración
powerled y otros componentes electrónicos a través
de una espuma de aluminio . Las propiedades únicas
de esta espuma de aluminio permiten un rendimiento
de refrigeración mucho mayor en comparación
con los convencionales . Las luminarias con LEDs
que utilizan la tecnología de Porifera tienen una
mayor eficiencia . Todo esto es posible a través de las
siguientes características:
• Gran superficie de refrigeración: la espuma de
aluminio ocupa una gran superficie del aspecto de la
luminaria, creando así una gran superficie dentro de un
volumen pequeño. Cuanto mayor sea la superficie de
refrigeración, más calor se puede disipar.
• Baja masa por volumen: la espuma de aluminio es muy
fina y aporta de esta manera una gran ventaja. El calor
se libera de forma inmediata con el medio ambiente
(aire) y no se almacena en la materia en sí como en los
sistemas convencionales. Estos sistemas tradicionales
tienen un efecto radiador es decir, el material se calienta
por completo y sólo entonces interactúa con su entorno.
Por lo tanto cuanto más grueso sea el material, más
lenta será la refrigeración. El bajo peso por volumen
de Porifera proporciona una baja capacidad calorífica.
Porifera reacciona casi instantáneamente a los cambios
de temperatura que resulta en los regímenes transitorios
muy corto, por lo que es un intercambiador de calor es
muy controlable.
• Porosidad: la estructura celular abierta permite un flujo
libre del aire a través de los laberintos de la espuma
asegurando así un intercambio de calor óptimo con el
medio ambiente.
• Isotropicó: las burbujas interconectadas forman un
camino tortuoso para los gases o líquidos que fluyen a
través de ellos. Este recorrido complejo pone los gases
en contacto continuo con las paredes de metal. Este
se traduce en un systema de transferencia de color
perfecto. Una ventaja adicional de esta estructura
isotropicó es que el calor se distribuye uniformemente
en forma tridimensional, por lo que el rendimiento
es independiente de la dirección de la corriente de
convección.

Las luminarias con LED que utilizan la tecnología Porifera
son mucho más eficientes que la refrigeración con
elementos de refrigeración convencional proporcionando
así una mayor longevidad y eficiencia de las luminarias.
La vida útil del LED y su eficiencia está directamente
relacionada con la temperatura de unión. Esta correlación
sigue una línea exponencial, es decir, más eficiencia de
enfriamiento tiene un enorme impacto en estos factores.

Porifera es un sistema de refrigeración pasivo que ofrece
todas las ventajas de un sistema de refrigeración activo
sin las desventajas: mayor eficiencia, sin necesidad de
mantenimiento y silencioso por completo.
Ventajas:
• Mayor vida útil del LED
• Mejora de la eficiencia del LED
• Menor consumo de energía
• Totalmente libre de mantenimiento

Experimental Performance
study Porifera
Due to its relatively high efficiency, its wide applicability
and especially its long life expectancy, LED lighting has
become one of the most promising technologies
in order to reduce energy consumption. LED can be used in
a wide range of applications. However the efficiency and life
expectancy depend strongly on the LED junction temperature.
The temperature reduction can be achieved in different ways.
The most applied solution is integrating a classical heatsink
with fan. However this solution has several disadvantages. The
solution proposed in this paper is using open cell metal foam.
This is a very light weight
structure, considering it consists for about 95 % out of
air.
APPARATUS AND PROCEDURE
The experimental setup consists of a rectangular heater
element with a length of 254.0 mm (10 inch) and a width of
25.4 mm (1 inch). To make the temperature distribution more
uniform, two copper plates are placed on top of this heater.
Between these two copper plates six thermocouples of type K
are installed. Above the upper copper plate the test sample is
attached.
Under this assembly and to its longest sides, guard heaters
are placed to minimize the heat losses. Three thermocouples
are placed on a copper plate which in turn is placed on the
bottommost guard heaters. On each of the lateral guard
heaters a copper plate with three thermocouples is placed.
Between the heater and the guard heaters and on top of the
lateral guard heaters Microtherm®’s Standard Block insulation
is positioned. Around this entity (except on the top surface)
more insulation is provisioned. Upon this a box was placed
with dimensions of 68.5 cm long, 60.0 cm wide and 45.0
cm high. To improve the conductivity between the different
components, a thermal paste is applied. The temperature
variations across the surfaces do not exceed 0,80 °C for a flat
surface. The main heater’s resistance is about 580 _ ± 15 %.
The main heater’s temperature varies between 55 °C and 95
°C for all measurements performed in this experiment.
The total heat loss is calculated as the sum of the heat loss of
the main heater’s to the guard heaters
(Qloss, 1), the heat loss occurring on the insulation’s top
(Qloss, 2) and the heat losses occurring at the heater’s
ends (Qloss, 3). The first heat loss is estimated conservatively
by calculating the heat loss as if it were a conduction loss
taking into account the temperature difference between the
main heater and the concerned
guard heater, the concerned guard heater’s surface, the
shortest distance between the main heater and the
concerned guard heater and the insulation’s conduction
coefficient (being 0.022 W/mK). This 1D conduction
32
2012 • 01
model is permitted because the temperature of all
heaters are presumed uniform and the corresponding
heat losses are considered to be small.
The second heat loss is calculated as the surface
integral of the product of the conduction coefficient
and the temperature gradient over the upper 5 mm of
the guard heater’s sides.
The temperature as a function of the area is derived
as the solution of a Robin problem. Solving the problem
shows that the heat loss can be neglected, so further on it is
presumed that Qloss, 2= 0. The third heat loss is calculated in
the same way as the second heat loss. This heat loss can also
be neglected, so further on it is presumed that Qloss,3= 0.
In this paper two types of metallic foam will be examined:
metallic foam of 10 PPI with a porosity of 93.73 % and
metallic foam of 20 PPI with a porosity of 93.31 %. The
maximal heights are respectively 40 mm and 18 mm. To
compare the results to each other as well as to compare them
to the results found in other papers, the Nusselt number will
be computed in function of the Rayleigh number. Therefore
the convection coefficient need be calculated as follows:
To compare the results for a flat surface, the convection
coefficient is calculated in the same manner, with the
exception that radiation heat is subtracted from the heat input
Q. The characteristic length (L*) is determined by following
formula:
RESULTS
To evaluate the test setup, the Nusselt number is calculated
from the measurements for different Rayleigh
numbers for an ordinary flat aluminum plate. In this
figure two trend lines for natural convection adjacent
to a horizontal flat surface are also depicted, namely
Lloyd and Moran’s trend line and Mikheyev’s trend
line. As can be seen, the trend line based on the experimental
data, which has a maximal error of ±3.2 %, is
in good accordance with Lloyd and Moran’s regression.
The trend line is in accordance with this regression

with a maximal difference of 4 %. The trend line is in
accordance with Mikheyev’s regression: the maximal
difference between both is 5 %. To verify the metal foam
height’s influence for the 10 PPI metal foam, measurements
have been performed for five different metal foam heights.
The metal foam height’s influence on the heat transfer is
clearly distinguishable. As the metal foam height increases,
the heat transfer improves. The increase is affected by raising
Rayleigh numbers. The increase however diminishes as the
metal foam height increases. Comparing the measurements
for different metal foam heights to the results obtained for a
flat surface, one notices that the latter curve is flatter. Finally
the obtained results are compared to the trend line obtained
by Phanikumar et al. Extrapolating the Nusselt number as a
power function of metal foam height using the test results,
one becomes the values as expected using Phanikumar’s trend
line.
To verify the influence of the metal foam height for the 20 PPI
metal foam, measurements have been performed for three
different heights. The metal foam height’s effect is clearly
visible. The convection coefficient and the corresponding
Nusselt number increase as the metal foam height increases.
The increase is affected by raising Rayleigh numbers.
Figure 1 measurements 20 PPI sample, different foam heights
The conclusion is valid for all trend lines. Moreover Nusselt
number augments as the metal foam height increases.
Finally the results are compared with the Phanikumar’s and
Hetseroni’s trend lines. Surprisingly the heat transfer for
Hetseroni’s 10 mm trend line is higher than the heat transfer
measured at a metal foam height of 12 mm. This can be
explained by the fact that in Hetseroni’s experiments the foam
was not attached to the base plate, it was clamped on both
sides instead . The sample was heated by sending a current
through the metal foam. Therefore the transferred power
was distributed more uniform over the metal foam, moreover
the air could move more freely through the metal foam.
Phanikumar’s trend line corresponds very well to the obtained
test results.

Figure 2 measurements brazed test sample vs epoxy glued
The metal foam can be connected to the base plate in
different ways, two of these are investigated in this work: the
first is called ‘brazing the metal foam to the base plate’, while
the second one is called ‘gluing the metal foam to the base
plate using epoxy glue’. The average improvement obtained
by brazing is around 11 % Finally Bhattacharya’s trend line
is compared to the obtained results. The trend line almost
depicts the same increase as does the 12 mm epoxy glued
metal foam trend line.
The influence of the pore density has also been examined. For
each metal foam height the heat transfer is less in the 20 PPI
metal foam. On average the Nusselt number increases with
about 20 % using the 10 PPI metal foam in comparison with
the 20 PPI metal foam.
The two metal foam types have also been compared to a
classical heatsink with a height of 18 mm. One can conclude
that at identical metal foam height 10 PPI metal foam causes
the greatest heat transfer, while the classical heatsink causes
the smallest heat transfer. In the 4,000 – 6,000 interval of
Rayleigh numbers, 10 PPI metal foam gives rise to Nusselt
numbers that are on average 70 % higher than those
corresponding to a classical heatsink. For 20 PPI metal
foam the effect diminishes to about 45 %.
In order to verify the influence of the box’s geometry,
18 experiments have been conducted. To perform these
experiments, metal foam height, box width, box height and
base plate temperature have been varied.
The obtained regression equation was:
