Motor and controller integrated structure water cooling system

Abstract

The invention discloses a water cooling system of a motor and controller integrated structure. The system comprises a driving motor and a motor controller which is fixed at one side of the motor controller. The system has the advantages that 1) in the whole motor-controller structure of integrated design, a heat radiating plate made of a copper material is arranged between the motor and the controller and thus, separates the work space of the motor from that of the controller, and cooling water flows on the copper plate to play a good heat radiation role; 2) the heat radiating plate made of the copper material plays a magnetism isolation role between the motor and the controller, so that a controller circuit is prevented from electromagnetic interference of the motor, and an electromagnetic shielding effect is realized; 3) water paths can be connected in parallel or series via a regulating valve according to the condition and season, the flow of the cooling water is adjusted, the motor and controller work at optimal working temperature, the heat radiation efficiency is improved, and the heat radiation effect is obvious; and 4) the arrangement difficulty in the whole vehicle is reduced, the length of a power line is reduced, the total weight and size are reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to a water cooling system with an integrated structure of a motor and a controller, belonging to the technical field of mechanical equipment. Background technique [0002] The existing motors and motor controllers are generally arranged separately, with large weight and volume, complex structure, high difficulty in layout, long power lines, poor heat dissipation structure, low heat dissipation efficiency, and high cost, especially in new energy vehicles. Due to the large changes in the structure of new energy vehicles, more compact mechanical structures are required to make room for the planning and layout of components such as battery packs. The existing separate arrangement of motors and motor controllers is difficult to meet the requirements. [0003] The existing way of combining the motor and the motor controller as a whole, its structure will produce electromagnetic interference, which affects the normal operation of the mot...

[0002] The existing motors and motor controllers are generally arranged separately, with large weight and volume, complex structure, high difficulty in layout, long power lines, poor heat dissipation structure, low heat dissipation efficiency, and high cost, especially in new energy vehicles. Due to the large changes in the structure of new energy vehicles, the mechanical structure requirements are more compact, making room for the planning and layout of components such as battery packs. The existing separate arrangement of motors and motor controllers is difficult to meet the requirements

[0003] The existing way of integrating the motor and motor controller into a whole, its structure will produce electromagnetic interference, which affects the normal operation of the motor and motor controller, and reduces the service life of the equipment

Secondly, the traditional motor and controller are separated by water cooling, the wiring of the water pipe is long, the arrangement of the water pipe is complicated, there are many hidden dangers of water leakage, and the reliability is poor

Secondly, the design of the traditional cooling water circuit is fixed, and the amount of cooling water cannot be adjusted through the regulating valve, and good heat dissipation cannot be obtained, so it is difficult to popularize
