Hi Everyone,
I recently completed a self build high power ebike. It has a 72v battery and I bought an expensive Grin Cycle Satiator charger for it which is great ,and a couple of cheap chargers from ebay for charging at work or to take with me when I'm traveling.The cheap chargers are cooled by a fan which is quite noisy and annoying when it's going in the background when I'm at work so I was thinking of transferring the innards of the charger to a diecast aluminium box with some heat sink compound to help the heat dissipate. The cheap chargers are only 3amp and 72v and don't seem to get particularly hot.
Basically I was wondering if anyone has any advice on this? Whether people generally think it's a terrible idea and if not if anyone has any tips on how to apply the heat sink compound to maximise heat dissipation? I would imagine the transformer is the bit that produces the most heat so if I put some heat sink compound connecting that to the body of the diecast case would that be enough? Would it matter if the heat sink compound all over the PCB as long it was the type that doesn't conduct electricity?
Thanks,
Matt
