Description

Technical Field

[0001] The utility model relates to a water-cooled integrated control heat dissipation structure, belonging to the technical field of heat dissipation structures for vehicle controllers. Background Art

[0002] With the rapid development of new energy vehicles, the industry's pursuit of products has become more and more strict. The integrated, miniaturized and lightweight electric drive system has become the mainstream direction for the future development of vehicle architectures, and high-integration controllers are the solutions for pursuing better designs. The higher the power of the controller, the greater the energy consumption, so special attention should be paid to the heat dissipation of each power module in the controller. How to improve the space utilization rate of the controller and more effectively meet the heat dissipation requirements.

[0003] Most controllers in the current market use the method of laying heating elements flat on the water channel for heat dissipation. However, this structure will make the length, width and volume of the controller relatively large, which affects the integration of the system, and only one side of the water channel is used for heat dissipation, resulting in waste of resources.

[0007] The further improvement of the technical scheme of the utility model is: the water channel includes a main water channel and a water channel cover plate; the water channel cover plate is welded on the controller housing and forms a sealed water channel with the main water channel.

[0008] The further improvement of the technical scheme of the utility model is: the IGBT power board is installed on the outer surface of the main water channel, and the damping resistor is installed on the outer surface of the water channel cover plate.

[0009] The further improvement of the technical scheme of the utility model is: a lower cover for sealing is arranged on the outer side corresponding to the damping resistor.

[0010] The further improvement of the technical scheme of the utility model is: the IGBT power board and the damping resistor are fixedly installed on the outer side surface of the water channel through heat-conducting silica gel.

[0011] Due to the adoption of the above technical scheme, the technical effects obtained by the utility model are:

[0021] In order to make the technical means, creative features, achieved purposes and effects of the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.

[0022] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0023] The utility model is a water-cooled integrated control heat dissipation structure, which is a heat dissipation structure on a new energy vehicle controller.

[0024] It mainly includes a controller housing 1, and a water channel 2 is arranged inside the controller housing 1. Heat dissipation is achieved by injecting flowing water into the water channel 2.

[0025] In this technical solution, two flat surfaces are included in the extending length direction of the water channel 2. The IGBT power board 3 is installed on one flat surface of the water channel 2, as Figure 1 shown. The damping resistor 4 is installed on the other flat surface of the water channel 2, as Figure 4 shown. And, a number of heat dissipation struts 6 are arranged on the inner side surface of the water channel 2 corresponding to the installation of the IGBT power board 3 and on the inner side surface of the water channel 2 corresponding to the installation of the damping resistor 4. By installing a plurality of heat dissipation struts 6, a large heat dissipation surface can be obtained, thus having a better heat dissipation effect. Specifically, as Figure 2 、 Figure 3 shown

[0026] Specifically, the water channel 2 includes a main water channel and a water channel cover plate 5. The closed water channel 2 is formed by the main water channel and the water channel cover plate 5. The water channel cover plate is usually installed on the controller housing 1 by welding method, and then the water channel cover plate 5 can form a sealed water channel 2 with the main water channel. For example, friction welding method is preferably used.

[0027] In a specific implementation, the IGBT power board 3 is usually installed on the outer surface of the main water channel, and the damping resistor 4 is installed on the outer surface of the water channel cover plate 5. Further, a lower cover 7 is arranged on the outer side corresponding to the damping resistor 4, and the setting of the lower cover 7 can play a sealing role. As Figure 5 shown.

[0028] In the specific implementation of this technical solution, the IGBT power board 3 and the damping resistor 4 are usually fixedly installed on the outer side surface of the water channel 2 through thermal conductive silicone, so that the heat generated by the operation of the IGBT power board 3 and the damping resistor 4 can be transferred to the water channel 2 more timely and quickly

[0029] In the present utility model, the IGBT power board and the damping resistor are respectively installed on the two outer side surfaces of the water channel (double-sided of the water channel), making full use of the outer side surfaces of the water channel, improving the utilization rate of heat dissipation; furthermore, it can reduce the space waste of the flat layout and reduce the complexity of the water channel, so as to achieve the purpose of integration, miniaturization and light weight of the controller.
