  • Pressurized and gravity-fed liquid cooling of electric motor
    Patent number: 10439477
    Abstract: A liquid cooling system for an electric motor includes: a pump for liquid to cool the electric motor; a heat exchanger that removes heat from the liquid; a manifold extending above a stator of the electric motor, the manifold receiving the liquid under pressure and having a first opening that directs a first liquid jet onto the stator; and a first tray above first end turns of the stator, the manifold having a second opening that directs a second liquid jet onto the first tray, the first tray having a third opening that performs gravity-fed liquid distribution onto the first end turns.
    Type: Grant
    Filed: January 31, 2014
    Date of Patent: October 8, 2019
    Assignee: Tesla, Inc.
