Figure 4.7a and b shows the typical design bf assembled r:adiator
collectors. The shape of the co.llectors is determined by the method
of assembly and inspection. Obviously, a seam can be welded and
checked reliably when the structure enables. inspection from tWo
sides. This is particularly important for the seam holding piped
1. This is why the pipes are welded to halfof the collector 2 i
first and th',: the collectors 2 and 3 are welded. For ,this both,
halves of tte collectors have' special crimps.
The shape of the radiating surface is shown ini Fig. 4.7b. A
thin aluminum or steel shell is welded oi. soldered to stainless
steel, niobium, or molybdenum pipes.'
The critical element of Ithe radiator is the binge, joint which'
provides for the unfolding of the radiator sections in spaced.
