I see some build with external heat sinks. I’ve searched but can’t see how they’re done. Is part of the box cut away & the heatsink is part of the VESC or is it an extra heatsink that is somehow connected to the VESC?
Not sure how others done it but this is how I did it on my tow boogie with pelican case.
- Cut out square from pelican case
- 10mm thick aluminum plate attached on the inside of the case
- Cut threads into plat and case hole boundary
- Fastened with bolts and appropriate sikaflex marine goo
- Cut threads into alu plate with same bolt pattern as VESC PCB attaches into stock heatsink
- Attached VESC to alu plate through bolts and added adhesive thermal sheets between PCB and alu plate
- Sprayed some conformal coating over the now exposed PCB (Might add 3D printed cover in future.
- Attached adhesive heatsink fins on outside of alu plate (Might change to a water-cooling block in future)
Hope it helps
