At a local workshop we have a portable and old heating device where the heat generator's housing reaches around 180°C during operation. The original external aluminum radiator with a fan attached to it have small dissipation capabilities. The integrated heat protection often trips that sometimes breaks our work waiting it to cool down a bit. We decided to give it a go and attach two old CPU tower-type coolers, each has 4 heat pipes to it.
The idea is to remove their pipes from their bases, straighten the pipes (slowly) and cross them so the fins are in the four directions and in one plane.
The problem is now clear; Which one is better for cross-connecting the pipes, soldering or brazing, Which will hold against the 180°C?
Note: That this will be a pure spare-time project before the better device arrives
