Abstract

A cooling structure for a power system, including a drive motor, a motor controller, a pump, a radiator, and a coolant; the drive motor includes a motor inner shell and a motor shell, and the motor shell is sleeved outside the motor inner shell and forms a The first liquid cooling chamber for circulating the cooling liquid. The motor controller includes a motor controller housing and a partition accommodated in the motor controller housing; the partition divides the motor controller housing into a controller housing chamber and a second liquid cooling chamber, the The first liquid cooling chamber communicates with the second liquid cooling chamber. The cooling liquid flows from the pump into the second liquid cooling cavity of the motor controller, then flows into the first liquid cooling cavity of the driving motor, flows out to the radiator, and then flows back to the pump. The cooling structure of the power system provided by the present invention optimizes the volume and cooling mode of the power system, thereby realizing light weight of the system and improving the cooling capacity of the system.

Description

【Technical field】 [0001] The invention relates to the technical field of electric vehicles, in particular to a power system cooling structure. 【Background technique】 [0002] In recent years, electric vehicles have been popularized on a large scale. The power performance of electric vehicles is the most basic and important performance among various performances, which largely determines the transportation efficiency of electric vehicles. The existing new energy pure electric vehicle power system is large in size, low in efficiency, and high in energy consumption. The temperature rise of the system is large during summer operation, which greatly reduces the cruising range and performance of the vehicle. [0003] In view of this, it is necessary to provide a new power system cooling structure to overcome the above defects. 【Content of invention】 [0004] The purpose of the present invention is to provide a cooling structure for a power system, which optimizes the volume and...
