A friend has a 3 phase large metal milling machine and the wiring box seems to get quite hot (i know that's a relative statement). I thought maybe a 80mm fan could be installed in the door and some holes drilled into the bottom of the case. Currently he runs the machine with the door open and a large fan pointed at the box. I'm not sure of the age of the machine nor the components but their doesn't seem to be any discoloration or burning smell indicating something obviously wrong. Where most of the heat is coming from is to the left of the transformer.
So the easiest solution would be tie the fan(s) into a 12v wall wart (making sure the current doesn't exceed the fan spec) but it would be nice to tap into the box itself ensuring the fans come on automatically.
Any thoughts/suggestions?
(sorry about the bad picture... came from my phone. If neccessary I can take a better pic and get component ID's.)
thanks!
