LIQUID-COOLED BEARING SYSTEM

摘要

A liquid- cooled bearing system including a bearing configured to support a rotatable component. The bearing includes a stationary friction surface or a race (216) defining a raceway (236). The bearing further includes friction reducing means in contact with the friction surface or the raceway of the stationary race. The stationary race is configured to support the rotatable component through the friction reducing means. The bearing further includes a surface remote from and not in contact with the raceway, to position a microchannel heat exchanger. The microchannel heat exchanger includes a fluid inlet and a fluid outlet. A closed-loop fluid circuit is configured to direct coolant fluid through the microchannel heat exchanger from the fluid inlet to the fluid outlet and back to the fluid inlet.
