Abstract
Official abstract text for this publication.
The present disclosure discloses a combined cooling system for a motor and a motor controller, which comprises a water cooling assembly, an oil cooling assembly, and an oil-water heat exchanger; one end of the water cooling assembly is connected to an cooling water outlet of the motor, the other end is connected to an cooling water inlet of the motor controller and/or a water inlet of the oil-water heat exchanger; one end of the oil cooling assembly is connected to a cooling oil outlet of the motor, the other end of the oil cooling assembly is connected to an oil inlet of the oil-water heat exchanger, and an oil outlet of the oil-water heat exchanger is connected to a cooling oil inlet of the motor. The above technical solution utilizes the temperature characteristics of the motor and the motor controller, and achieves the objects of saving energy in cooling, and improving high power output performance and environmental adaptability of the motor through the cooperation and intelligent control of the water pump, oil pump and fan in the combined cooling system.
First claim
Opening claim text (preview).
What is claimed is: 1. A combined cooling system of a motor and a motor controller, wherein the cooling system comprises a water cooling assembly, an oil cooling assembly, and an oil-water heat exchanger; the water cooling assembly comprises a radiator, a fan, a first water pump, and a water pipe, the radiator is connected in series with the first water pump, and the fan is used for cooling the radiator; the oil cooling assembly comprises an oil pump and an oil pipe, and the oil pump is connected in series between the cooling oil outlet of the motor and the oil inlet of the oil-water heat exchanger via the oil pipe; one end of the water cooling assembly is connected to a cooling water outlet of the motor, the other end of the water cooling assembly is only connected to a cooling water inlet of the motor controller, a cooling water outlet of the motor controller is connected to a water inlet of an oil-water heat exchanger, and a water outlet of the oil-water heat exchanger is connected to a cooling water inlet of the motor; and one end of the oil cooling assembly is connected to a cooling oil outlet of the motor, the other end of the oil cooling assembly is connected to an oil inlet of the oil-water heat exchanger, and an oil outlet of the oil-water heat exchanger is connected to a cooling oil inlet of the motor. 2. The cooling system according to claim 1 , wherein the motor controller, the water cooling assembly and the oil cooling assembly are controlled by a controller. 3. The cooling system according to claim 2 , wherein the controller is a vehicle controller or a cooling system controller.
