Water cooling question for all

[skyhighdiver]

So I have made this response on a different thread and got to response so I am starting it here as a stand alone


If you put a y in your line from the water inlet and then feed to motor and esc with separate lines is this not robbing both of cooling?

My thereby is this, water like any other fluid takes the path of least resistance. If I put a Y in the line and use two outputs the rudder can still only pick up so much water by splitting it you already in effect have cut the supply in half and if motor and esc lines are not same length you cut the water supply to the longer line more. Therefore although you may be feeding slightly warm water from the esc to motor on a single line you are getting more flow is this still not better than putting in Y and less flow.

What are you guys doing?

I never use a "Y" to split the cooling flow. You are correct, the water will flow a larger volume through the leg with the least pressure drop. What this usually means is that the typical ESC will get the most water, the motor will get less. An ESC lith a lot of tubes like a Hydra 240 will have more resistance than a Turnigy 180.

Bottom line, the ESC is the most critical component and should get the coolest water. There is no problem runing a single cooling line with the ESC and motor in series, both will cool well. An additonal complication is that excess water flow can reduce overall cooling, but no one wants to hear that.
