Description

Technical Field

[0001] The utility model relates to the technical field of charging equipment, in particular to a structure of a liquid-cooled charging module. Background Art

[0002] With the rapid development of electric vehicles and electronic devices, the demand for charging speed and efficiency is increasing. Currently, common charging modules generate a large amount of heat during high-power charging. If heat is not dissipated promptly and effectively, the module will overheat, affecting charging efficiency and safety, and even damaging the charging equipment.

[0003] Existing heat dissipation methods mainly include air cooling and natural heat dissipation. Air cooling is noisy and has limited heat dissipation, especially in high-temperature environments, making it difficult to meet the heat dissipation requirements of high-power charging modules. Natural heat dissipation is inefficient and cannot cope with the high heat generated by fast charging.

[0004] To this end, it is urgent to develop a charging module that can dissipate heat quickly and efficiently. Utility Model Content

[0005] In response to the above problems, the present invention provides a liquid-cooled charging module structure, which has an efficient and reliable heat dissipation effect, improves charging efficiency and safety, and extends the service life of the charging equipment.

[0008] PFC board, the back end of which is provided with a PFC corresponding interface;

[0009] Liquid cooling plate assembly, which includes a liquid cooling plate body and two sets of water inlet and outlet nozzles;

[0010] The DC board has a DC corresponding interface at its rear end;

[0011] lower shell assembly;

[0012] and end cap plates;

[0013] The upper cover assembly and the lower shell assembly are combined to form a cavity structure with an open front end. The first plate body of the PFC plate is arranged toward the flat plate body of the upper cover assembly. The second plate body of the DC plate is supported on the upper surface of the flat plate body of the lower shell assembly. The PFC plate, the liquid cooling plate assembly, and the DC plate are arranged sequentially from top to bottom. The first plate body of the PFC plate is provided with a plurality of downwardly protruding first heat conduction blocks, the bottoms of the first heat conduction blocks being arranged in contact with the upper surface of the liquid cooling plate body. The second plate body of the DC plate is provided with a plurality of upwardly protruding second heat conduction blocks and a third heat conduction plate, the upper surfaces of the second heat conduction blocks and the third heat conduction plate being arranged in contact with the lower surface of the liquid cooling plate body. The end cover plate is mounted on the front end opening of the cavity structure to form a closed structure. The end cover plate is provided with avoidance notches corresponding to the positions of the water inlet and outlet nozzles. The two groups of water inlet and outlet nozzles include one water inlet nozzle and one water outlet nozzle.

[0014] It is further characterized by:

[0015] The upper cover assembly includes an upper cover and an upper cover insulating film. The upper cover includes an upper cover flat plate body, first vertical plates on both sides, and a first rear end vertical plate. The upper cover insulating film includes a first flat film body and first vertical films on both sides. The first rear end vertical plate of the upper cover is free of insulating film. A first interface notch is provided on the first rear end vertical plate of the upper cover. The first interface notch corresponds to the PFC corresponding interface setting.

[0016] The lower shell assembly includes a lower shell and a lower shell insulating film. The lower shell includes a lower shell flat plate body, second vertical plates on both sides, and a second rear end vertical plate. The lower shell insulating film includes a second flat film body and second vertical films on both sides. There is no insulating film on the second rear end vertical plate of the lower shell. A second interface notch is provided on the second rear end vertical plate of the lower shell. The second interface notch corresponds to the DC corresponding interface setting.

[0017] The upper and lower surfaces of the liquid cooling plate body are provided with a plurality of connection positioning threaded holes, and the first heat conduction block, the second heat conduction block, and the third heat conduction plate are fixed to the corresponding connection positioning threaded holes by connecting bolts, so that the PFC board, the liquid cooling plate assembly, and the DC board are reliably connected;

[0018] The liquid cooling plate body is provided with a plurality of positioning threaded holes on the vertical surface in the thickness direction. The first vertical plate and the second vertical plate are provided with corresponding first connection holes at the butt joint positions. The first rear vertical plate and the second rear vertical plate are provided with corresponding first connection holes at corresponding positions. The locking screws pass through the corresponding first connection holes on the upper cover and the lower shell and are then threadedly connected to the positioning threaded holes on the liquid cooling plate body, so that the entire connection is stable and reliable.

[0019] Both ends of the end cover plate are also fixed with forward-protruding handles, which ensure that the entire charging module is easy to transport.

[0020] With the structure of the present invention, the liquid cooling plate body is securely positioned at a height between the PFC board and the DC board. By providing a first heat conduction block on the PFC board and a second and third heat conduction blocks on the DC board, in addition to heat directly dissipated by the heat-generating components being transferred to the surface of the liquid cooling plate body, the corresponding heat conduction bodies transfer heat to the surface in contact with the liquid cooling plate body. The cavity of the liquid cooling plate body exchanges cooling medium through two sets of inlet and outlet nozzles, thereby reliably dissipating heat generated within the charging module. This significantly improves heat dissipation, ensuring that the charging module maintains a low temperature even during high-power charging, thereby improving charging efficiency. Compared with air cooling and natural heat dissipation, liquid cooling has higher heat dissipation efficiency, effectively reducing the temperature of the charging module and mitigating the problem of decreased charging efficiency due to high temperatures. Furthermore, the liquid cooling system operates with minimal noise, providing a quieter charging environment compared to air cooling. Effective heat dissipation avoids safety hazards such as fires caused by excessive temperatures, extending the service life of the charging equipment. Furthermore, the liquid cooling system is adaptable to various harsh environments and is unaffected by the external ambient temperature, capable of stable operation in harsh environments such as high temperature and high humidity.

The first interface notch 114 corresponds to the PFC interface 201.

[0038] Its operating principle is as follows: the liquid cooling plate is securely positioned at a height between the PFC and DC plates. A first heat conduction block is installed on the PFC plate, and a second and third heat conduction blocks are installed on the DC plate. This ensures that, in addition to the heat directly dissipated by the heat-generating components being transferred to the surface of the liquid cooling plate, the corresponding heat conduction elements transfer heat to the surface in contact with the liquid cooling plate. The cavity of the liquid cooling plate exchanges cooling medium through two sets of inlet and outlet nozzles, thereby reliably dissipating heat generated within the charging module. This significantly improves heat dissipation, ensuring that the charging module maintains a low temperature even during high-power charging, thereby improving charging efficiency. Compared to air cooling and natural heat dissipation, liquid cooling offers higher heat dissipation efficiency, effectively reducing the temperature of the charging module and mitigating the drop in charging efficiency caused by high temperatures. The liquid cooling system also operates with minimal noise, providing a quieter charging environment compared to air cooling. This effective heat dissipation avoids safety hazards such as fires caused by excessive temperatures, extending the service life of the charging equipment. Furthermore, the liquid cooling system is adaptable to various harsh environments, unaffected by the ambient temperature, and can operate stably in harsh environments such as high temperature and high humidity.
