water cooler for finned motor?
 

yes its for a boat
anyone got any ideas on how to build a water cooler system for a neu castle 2200kv motor

I'm thinking of just making a coil around motor with aluminum tubing...would copper be better?...easier to bend

be pretty nice if you could devise some way of making a slightly bigger can to fit around the fins and sealing the ends with o-rings and sealant like on the smooth can coolers where the water actually flows over the motor

Coils wont work at all well with a finned motor, very little contact area.

if you could find a metal/ plastic sleave just slightly larger than the motor diameter, and seal it like you said (or with silicon/jbweld etc), it would be easy to install the nipple inlets and then run the tubing where it needs to go.

Find copper small enough to fit in between the fins, and you could make a very effective one.

That occured to me too, but the tubing would need to be ~3mm OD at most by the looks of the motor, never seen anything that small very often. Copper would be best though yeah, better conductor or heat so far as I know compared to aluminium.

how big of a boat?

Find a lathe...

Or send to NEU pay some $ and ask for a smooth can...

Its a 29" Catermaran mean machine

Personally id go with the tube idea.


1. Id Lathe out a tube of copper or aluminum to fit snug on the fins
2. Lathe and weld some bungs for the water inlet
3. Grind the fins right over the bung about 1/4" so the water flows around the motor
4. Seal with some silicon or anything similar.

edit: I posted without reading your last paragraph & I now assume you have a finned can? They do a larger one that may fit over fins although I doubt it would be effective even if it did

why?...same principle

The fins on the can prevent full contact with the cooling jacket & trap hot air inbetween the fins which then expands, pushing the cooling jacket further away...etc
