Waterproof case for VEC Controller

[Pedrotorres]

Hello all,

My setup is a HPM3000 48V motor and a VEC240 controller. My application to use it on a boat as an outboard. On this, I am assuming that this controller is not waterproof and I wonder wether is possible to enclose this controller in a sealed waterproof box without consider any overheat effects. Any thoughs on the ventilation requirements (considering the huge heatsink this controller has)?

Hi Pedro andto the forum.

As the controller's heatsink is responsible for the majority of the controller's cooling, a water cooled heat sink plate could be installed inside the waterproof box to ensure that the controller is sufficiently cooled inside the sealed box:

Using an aluminium box would also help to dissipate any additional heat that was not directly absorbed by the cooling plate.
