Cooling Options for a Bearing

[khayashi]

I am looking for alternate methods to cool the upper bearing of a motor. Currently the bearing is designed to use 31 L/min (491 gallons/hr) of water through water cooling coils. I am trying to find options that would reduce the amount of water used or another method.

some useful information...
the bearing: model EVEKU-07 by Renk
the motor: model ANVE-WT001 by TECO WESTINGHOUSE
(a three phase induction motor)

If you have any information that may help, please let me know. Thanks!!

How are you planning on getting a cogent answer if you don't reveal the amount heat to be removed?

You can review an air cooled bearing option. This would probably require some engineering modification to the existing bearing bracket and a re-design of the bearing itself to properly dissipate heat.

Possibly the least awful solution is to circulate water/glycol through the extant plumbing, and cool that with a radiator and a fan.

Why add the glycol?

To keep the water from eating the radiator.

But that would require a larger flowrate to cool the same bearing which is the opposite of what he was looking for.

Somehow I got the impression the OP was talking about "cooling coils" embedded in the bearing housing, and using the water exactly once and dumping it, i.e. "water used".

Hey, I could be wrong; it happens every day.

It never crossed my mind that he may be dumping all the water, I just assumed that was a closed loop process.

If changing to a closed-loop cooling system, look at using a laser or welder chiller (refrigeration type cooler) instead of ambient radiator. You then set the water temperature just above condensation temperature (not to make water in the bearings) and remove more heat this way.

We used some similar heat exchangers on high temperature fans and motors.
