A cooling method and device for an automobile motor system

Abstract

The invention discloses a cooling method of an automobile motor system. The cooling method comprises the following steps of: firstly, judging whether pressure of gas in a gas storage device meets the original operation requirement of the gas storage device, and cooling the motor system on the basis of meeting the original operation requirement of the gas storage device; and while cooling the motor system, detecting the pressure of the gas at the inlet of a cooling pipeline, and judging whether gas smoothly passes through the whole cooling pipe. In the cooling method of the automobile motor system, the temperature of the motor system is constantly detected when the gas in the gas storage device is utilized to cool the motor system, and the flow of the cooling gas is controlled according to the temperature of the motor system; the gas can be directly discharged into the atmosphere after cooling the motor system without arrangement of a circulating device, the whole structure is concise, and the assembly is convenient; and meanwhile, the cooling method is strong in operability and can be used for effectively and reliably cooling the motor system. The invention also discloses an automobile motor system cooling device which uses the cooling method.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a cooling method and device for an automobile motor system. Background technique [0002] The motor is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction, and is the core component of hybrid electric vehicles and electric vehicles. A motor is usually controlled by a motor controller for its motion. [0003] The motor system is the main executive structure of the vehicle, and its driving characteristics determine the main performance indicators of the vehicle, and it is an important part of the vehicle. The motor system includes a motor body and a motor controller. [0004] The stable operation of the motor system directly determines the operation of the car. The cooling problem of the motor system affects the performance of the motor system to a large extent, and then affects the operation of the...

AI Technical Summary

Problems solved by technology

The recycling of cooling water makes the layout of water outlet and circulation loop extremely complicated

When the temperature of the cooling water attached to the car exceeds the limit value, it must be replaced or stopped, otherwise it will affect the operation of the car

[0006] When the cooling method of the motor system adopts forced air cooling, the way of installing the fan can only play the role of cooling the surface, the cooling effect is poor, and it is very easy to blow impurities and dust in the atmosphere into the motor and controller, affecting its performance
