cooling avionics
(OP)
Hello,
I need some help at cooling an aircraft LRU. I don't need a usual fan, I need a system that knows how to "manufactor" cold air and blow it on my LRU. I shold be as smaal as possible. Does anybody know a company that manufactor these kind of systems?

RE: cooling avionics
This is a less-than-zero sum game. If you pass the buck, it just makes the problem worse, because now you have to remove the heat generated by the upstream equipment.

This LRU is being placed in a cell that is cooled by other system. Actually, this LRU needs air in low temprature, while the other LRU in the cell can live with the conditions in the cell. I assume that the big system can handle another LRU that is heated while cooling my poor LRU...
Thank you!

Furthermore, adding more parts is a sure-fire way to decrease reliability. What happens if the cooling system fails? Apparently your LRU fails. Everyone would be better off if you designed your LRU to cope with the conditions it will be exposed to.
RE: cooling avionics
In general, however, I agree with the other posts. It's far better to design the LRU to handle the existing environment with appropriate component placement, heat sinks, ducting, copper planes, etc.

Even if you designed a TE cooler that was mechanically interfaced directly to your heat exchanger or, even better, your heat sources, your overall efficiency would be substantially better.
