[0002] As an indispensable component of power systems, the development trend of motor controllers is towards miniaturization, lightweighting, modularization, and integration. Current technology commonly involves directly mounting the power module onto the motor controller housing, which faces problems such as inflexible space layout, low space utilization, difficult after-sales maintenance, and complex assembly; moreover, the motor controller itself also generates a significant amount of heat during operation.

[0003] Therefore, those skilled in the art are dedicated to developing a water-cooled mounting base plate for a motor controller that is simple in structure and highly integrated. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a water-cooled mounting base plate for a motor controller that is simple in structure and highly integrated.

[0005] The objective of this utility model is achieved through the following solution:

[0006] A water-cooled mounting base plate for a motor controller includes a main body. A power module mounting slot is located in the center of the front of the main body. Water inlet and outlet channels, communicating with the power module mounting slot and located on the back of the main body, are respectively provided on both sides of the main body. Several mounting supports are arranged around the outer side of the main body. The power module is installed in the power module mounting slot, which is then sealed with a cover plate. The water inlet and outlet channels are connected to the vehicle's water pipes, or they can be connected to the water channels of the motor controller housing to achieve water circulation. This allows the water in the circulation system to quickly remove the heat generated by the power module. This design combines the power module and motor controller water channels of existing technologies, improving the integration of the motor controller and saving space.

[0007] Furthermore, the water inlet channel is composed of a water inlet trough and a water inlet cover plate that is sealed on the water inlet trough. The water inlet cover plate is provided with a through water inlet, and the bottom of the power module mounting slot is provided with a water inlet outlet.

[0008] Furthermore, the water inlet tank is provided with a water inlet sealing platform for accommodating the water inlet cover plate. The water inlet cover plate is welded to the water inlet sealing platform, which provides a firm seal, good sealing effect, and prevents water leakage.

[0009] Furthermore, the water outlet is composed of a water outlet trough and a water outlet cover plate that is sealed on the water outlet trough. The water outlet cover plate is provided with a through water outlet, and the bottom of the power module mounting slot is provided with a water outlet inlet.

[0010] Furthermore, the water outlet trough is provided with a water outlet sealing platform for accommodating the water outlet cover plate. The water outlet cover plate is welded to the water outlet sealing platform, which provides a firm seal, good sealing effect, and prevents water leakage.

[0011] Furthermore, a sealing groove is provided on the end face of the power module mounting slot, and a sealing plate is covered on the end face of the power module mounting slot. The sealing groove is filled with sealant, resulting in a good sealing effect.

[0012] Furthermore, the mounting point is a threaded hole, which facilitates assembly with relevant parts on the vehicle.

[0013] Furthermore, the power module mounting slot can be designed with heat dissipation fins of different shapes to improve heat dissipation efficiency.

[0014] The advantages of this utility model are:

[0015] 1. The power module and motor controller water channel are combined, which improves the integration of the motor controller. The structure is simple and compact, and occupies little space.

[0016] 2. It uses several mounting points to assemble with relevant parts on the car, which is simple to assemble and has low manufacturing cost.

[0017] 3. The water-cooled mounting base plate is integrated with the power module, making assembly simple and maintenance convenient. Attached Figure Description
