Title:
MOTOR UNIT, TEMPERATURE ADJUSTMENT SYSTEM, CONTROL METHOD FOR TEMPERATURE ADJUSTMENT SYSTEM, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/229858
Kind Code:
A1
Abstract:
A motor unit 30 comprises: a motor 33 which drives a vehicle 10; and a motor-side pipeline 30M through which a first heat medium heated by a heater 101 flows and which carries out heat exchange between the first heat medium and the motor 33. The motor-side pipeline 30M is connected to a battery-side pipeline 20B which carries out heat exchange between the first heat medium and a battery 20 of the vehicle 10. Flow rates of the first heat medium which flows to the motor-side pipeline 30M and the battery-side pipeline 20B are adjusted by a mixing valve 500 and pumps 110. The first heat medium carries out heat exchange with a second heat medium which flows through an air-conditioning-side pipeline 40A of an air conditioning device 40 of the vehicle 10, and is different from the first heat medium.
