AMS Technologies | Thermal Management SolutionsHeat sinks for forced convection with airWebra heat sink profiles are aluminum extrusions that have proven their value in the most demanding industry tasks:Cooling of inverter modules in renewable energiesCooling of power semiconductormodules for traction and auxiliary powerunits in rail vehiclesCooling of frequency converters as insoft starters or in large drives06 Heat Sinks

Cooling of power amplifier components,i.e. for telecommunication or broadcastingRe-cooling of thermoelectric modules,i.e. for cooling laser diodes or reagentsCooling of batteries and Power Electronics inElectric- and Hybride VehiclesHeat Sinks 07

AMS Technologies | Thermal Management SolutionsExceptional PerformanceWebra uses patented and protected technologies in order to optimize the geometry of heat sink profiles. Significantparameters for the unrivalled performance in the industry are:Surface enlargementfor heat transfer and adjusted flow crosssection for pressure drop minimizationUnhindered heat conductionfrom the heat sources to the fin surfacePerformanceverified in the wind tunnel08 Heat Sinks

Safety and long lifeThe patented heat sink profiles are manufactured froma single aluminum extrusion. They offer a significantadvantage compared to competitors’ profiles that havethermal resistances at the joints of pressed-in, rolled-inor glued-in fins and thus experience the risk of aging andperformance loss.Webra’s safe construction made of a single piece is withoutrisk, its high thermal performance always remains the same.Webra’s safe constructionmade of a single piece, unhindered heat flowCompetitors’ constructionwith rolled-in fins, risk of aging, looseningof fins and performance lossHeat Sinks 09

AMS Technologies | Thermal Management SolutionsDimensioning using numerical methodsThermal simulation with computational fluid dynamics (CFD)allows the engineer to dimension his system in great detail.Especially in complex systems life expectancy of electroniccomponents, space, mass and cost may be optimized.The analysis of temperatures and air flows allows to taketargeted measures such as adjusting air flow, positioningof power components, dimensioning of heat sinks and fansand others. AMS Technologies conducts thermal simulationsince 2000 and has authored more than 200 reports forcustomers.Homogeneous temperature distribution is achieved in despite of asymmetricalair flow using fine tuned air baffles.
