[0069] The technical features mentioned above, the technical features to be mentioned below and the technical features shown in the drawings alone can be combined with each other arbitrarily, as long as the combined technical features are not contradictory. All feasible feature combinations are the technical content explicitly described herein. Any one of the multiple sub-features included in the same sentence can be applied independently, and does not have to be applied together with other sub-features.

[0070] The present scheme will be further described below in conjunction with specific embodiments:

[0071] In one scheme, the power distribution assembly is composed of an upper cover plate, a high-voltage distribution box module (PDU), a DC converter module (DCDC), a case, a vehicle-mounted charger module (OBC) and a lower cover plate.

[0072] The high-voltage distribution box, the DC converter and the vehicle-mounted charger are key components for realizing battery charging, high-voltage power distribution and DC voltage conversion functions of new energy vehicles; these key components are usually arranged in various ways in the case as a carrier.

[0073] In the present scheme, the DC converter module and the on-board charger module each adopt an independent heat dissipation shell to take away the heat of the heat generating device in time. The heat dissipation shell is connected and fixed with the PCB board by screws to form a module, so that different modules can be selected according to different power and different functions, and the design of customizing the case and the resulting case compatibility problem caused by directly fixing the heat generating device of the DC converter module and the on-board charger module in the case are reduced.

[0074] The arrangement of the heat dissipation water channel greatly affects the heat dissipation efficiency. In the present scheme, the main heat generating modules (DC converter module and on-board charger module) are reasonably arranged, and the upper and lower surfaces of the heat dissipation water channel are used for heat dissipation. The DC converter module is arranged on the upper surface of the water channel for heat dissipation, and the on-board charger module is arranged on the lower surface of the water channel for heat dissipation, so as to maximize the heat dissipation of the water channel surface. Since the heat dissipation surface of the water channel is designed as a plane, the case can be compatible with more function boards and control boards, and the operation space is large. At the same time, the volume of the DC converter module is smaller than that of the on-board charger module, so that the high-voltage distribution box module can be arranged above the DC converter module to provide the utilization rate of the internal space of the case.

[0075] In another scheme, the CDU three-in-one structure is arranged. The DC converter module and the high-voltage distribution box module are arranged in the upper cavity, and the on-board charger module is arranged in the lower cavity. In this case arrangement, the on-board charger module in the lower cavity can be replaced by a control board module. In this case arrangement, the DC converter module or the power resistor module in the upper cavity can be replaced by a boost inductor module to increase the richness of the function selection.

[0076] The key points or points to be protected of the present scheme are as follows:

[0077] The present scheme realizes the modular structure arrangement of the DC converter module and the on-board charger module, which is beneficial to the portability of the DC converter module and the on-board charger module, the interchangeability between different power modules, and the performance requirements of various customers. The present scheme realizes the efficient heat dissipation of the water channel of the case from both sides, ensures the flatness of the water channel of the case, and can replace the DC converter module and the on-board charger module with other function modules in the internal space of the case, so as to increase the availability of the case and shorten the development cycle by using ready-made modules.

[0078] Each embodiment in the present specification is described in a progressive manner, and each embodiment focuses on the difference from other embodiments. The same or similar parts between each embodiment can be referred to each other.

[0079] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
