Liquid cooling questions (sevcon)

[vtbrammorider]

Working on liquid cooling for the controller and wanted to see if anyone has found a better cooling plate solution than this at 140$

Went with the above plate and am in the hose routing phase.

Bleeding is taking approximately forever... the angle of the cooling plate makes air enjoy hanging out there but at this point it seems to be not leaking so I switched over to ahrma legal coolant.  I'm able to run the pump off of the wall which I plan to keep as a feature for the future.

I do not understand what the problem to be solved to make this?

On the track if you can overcome your batteries overheating (which I do by precooling them) the next weakest link is the controler.  This is an attempt to keep the bike from going into thermal cutback due to the controller.  Unfortunately I won't be able to test it until March because detroit weather doesn't like motorcycles.

Any updates on this modification?

I ran it at NOLA and at gingerman.  Not perfect but it does seem to give me an extra lap or so before thermal cutback.

How about some thermoelectric cooling?

Does take some oomps from the battery but might be worth it in the end...
