Liquid Cooled Brushless System - Goodbye Fans?

[BrianG]

Those little refrigerators use a Peltier junction device and they can take considerable amount of current (5-10A) to run. That would effect runtime. They work by passing a current though it and one side gets cold and the other gets hot. So, when you hook the cold side to the motor, it pulls the heat over to the warm side. So, not only do you have to dissipate the motor heat but also the heat the device creates.

Personally, if your motor gets hot enough where you need a watercooled system (or other exotic cooling syste), you don't have the gearing right and the motor isn't loaded enough (or maybe even too much). It kind like the Nitro world where people replace the cooling head with a really large one to compensate for a lean condition. It doesn't solve the problem, just the symptom.

Plus, this creates more wiring and mechanical mess and just adds to the complexity of the whole thing. Just one more thing to go wrong IMO...

An idea is just getting the pump (if they have it available separately) and then use it in conjunction with the Traxxas Cooling System meant for their boats.

It has a metal tubing coil that goes around the motor can. Water flows through the tubes and trasfers heat to the water. I've thought of this, but I've never been able to find a pump and radiator that were suitable. If I could get this pump and radiator for under 100 bucks...I would give it a try.

try your luck in the computerworld.

Rhylsader, a user on this forum, made a water cooled brushless setup.

I've sketched out a design for water cooling but have not yet built one. Perhaps in my "copius free time" I will. LOL.
