Al,
What in your opinion would be a good test setup? Do you think (compressor--> pressure release valve --> 2 air tanks) would suffice?
In our experience existing heat sink (a.k.a. compressor head) with small fan (40mm zip tied directly on it) was doing decent job cooling it. However, rest of the compressor still heated up a lot. Idea is to have this new heat sink + heat sink for the motor body would + 2 80mm fans dissipate a lot of heat and thus increasing duty cycle. As I stated before, another my objective was to design heat sink in such a way that would require only basic tools to make (hole cutter drill attachment, metal saw, and may be dremmel) as we dot have access to CNC nor to even basic milling machine. Considering that objective I knew that it may cause less efficient heat sink design because it would be harder to make more elaborate shapes of pieces. However, if it will be efficient enough, than
ANY other team would be able to produce it.
At the moment best idea I came up with is to use 1/8" x 1.5" x 8' aluminum flat bar easily available here for $20. for this heat sink I need 14 pieces 3" length, that makes 42 inches. lets say 48" with some waste - that only $10 worth of materials.
Motor body heat sink would need a bit more. But it still falls under $40.
