2009 Mini Cooper Clubman drivetrain update and the MES-DEA motor fiasco. For the 1957 Porsche Speedster Rickard Electric version, we discuss cooling issues and demonstrate a chillplate for the Curtis 1238 3-phase controller. Part 8 of 11 Full length version at http://EVTV.
If your circular heatsink has smaller surface area than the square one, you're actually going to reduce your heat transfer away from the controller unit. Water will only transfer your heat away from the controller to the circular heatsink, but if the heatsink won't dissipate that heat fast enough, it will become as hot as the controller plate. Especially as the heatsink doesn't have any fan to remove the heat from it. You may want to install a 50 or 80mm computer fan on the circular edge.
