Bear with me... this is kind of random.
I've got decent practical electrical knowledge and build my own computers, but never plunged into water cooled setups.
I'm building an electric car:
I finally got it driving, but I'm having issues with my motor controller overheating and cutting back power levels to useless output after a little while.
It's a fully potted controller, waterproofed with a single weak factory fan to active air cool the copper heatsink:
.
I'm doing a continuous duty of 20,500 watts to the motor, so I'm probably looking at several hundred watts of heat needing to be pumped out from controller inefficiency. I wanted to do a combination TEC+ liquid cooling blocks mounted directly on the copper. I'll be using a thermal epoxy to secure them.
I have purchased 4 of these cooling blocks:
Specs: 162mm x 41mm x 12mm. I'm getting conflicting information about the internal/external port diameter. One review stated, "5/16 ID works but could be a little tighter." Another review said, "the barbs are like 3/8". I need help figuring out proper adapters + correct tubing to use on this.
I picked up this for my reservoir:
Specs: 250mL volume, "Threaded 1/4 G" (Not sure what this is exactly)
I need help with:
1) Selecting a solid reliable pump (or several?) for my multiple cooling blocks. Advice?
2) Any suggestions on good sized peltier (TEC) cooler? I am running a 30AH 14.8v nominal system, peaking at 16.8v full charge. I would prefer not to step it down but can if necessary.
3) tubing, any necessary connectors + adapters. I need reliable fittings, but I don't know what to get.
Do I need a radiator? If so... school me on it please!
I already have any fans and heatsinks necessary for the rest of it. Any help would be greatly appreciated!
