[0017] In order to make the technical solution and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0018] like Figure 1 As shown, a novel water-cooling plate for an electric control system includes an upper cover plate 1 and a lower cover plate 2 which are integrally formed. The inner sides of the upper cover plate 1 and the lower cover plate 2 are used to connect with the drive motor and cool and dissipate heat, and the upper cover plate 1 is used to connect with the capacitor module, and the lower cover plate 2 is used to connect with the PCB board. At the same time, a water nozzle 3 is provided on the outer side of the upper cover plate 1, and a metal inlay 4 is provided on the outer side of the lower cover plate 2.

[0019] The lower cover plate 2 has a mounting groove 21 disposed inside thereof, and the PCB is fixedly mounted in the mounting groove 21. The lower cover plate 2 has a connection port 22 disposed outside thereof, and the metal inlay 4 has an outer ring embedded portion 41 that matches and seals the connection port 22.

[0020] Among them, when manufacturing the integrally formed upper cover plate 1 and lower cover plate 2, the stamped copper busbar and the upper cover plate 1 are subjected to an injection molding process to obtain a corresponding integral structure, and then the metal inlay 4 and the lower cover plate 2 are subjected to an injection molding process to obtain a corresponding integral structure, and then the faucet 3, the upper cover plate 1 and the lower cover plate 2 obtained by injection molding are welded into an integral structure by an infrared welding process.

[0021] It is worth mentioning that Figure 2 , Figure 3 As shown, the metal inlay 4 is provided with a metal port 42 and a circulation channel. One end of the circulation channel is connected to the metal port 42, and the other end is used to communicate with the water nozzle 3. A circulation heat dissipation cavity 11 for connecting the water nozzle 3 with the corresponding end of the circulation channel is provided on the inner side of the upper cover plate 1. Therefore, the metal inlay 4 cools the lower cover plate 2 and the circulation heat dissipation cavity 11 cools and dissipates heat to the upper cover plate 1 and the drive motor, so that the interconnected metal inlay 4 and the circulation heat dissipation cavity 11 form a circulation channel, thereby achieving the purpose of effective cooling while improving the integration, and ensuring the normal operation of the PCB board and the capacitor module.

[0022] It should be mentioned that a sealing ring 12 is provided on the inner side of the upper cover plate 1 and located outside the circulation heat dissipation cavity 11, so that the upper cover plate 1 forms a stable sealing structure when connected to the drive motor, thereby avoiding the problem of cooling water leakage. At the same time, connection ports 13 are provided at both ends of the circulation heat dissipation cavity 11 along the length direction, and the two connection ports 13 are respectively used to communicate with the corresponding circulation flow channel and the water nozzle 3, so that the cooling water can fully absorb the heat of the drive motor during the flow process to achieve an effective cooling and heat dissipation effect.

[0023] like Figure 2 , Figure 3 As shown, the water nozzle 3 is provided with a sealing connector 31. Correspondingly, a connection portion 14 for contacting and sealing with the sealing connector 31 is provided on the upper cover plate 1, so that a stable sealing structure is formed between the water nozzle 3 and the upper cover plate 1 during industrial welding by infrared welding. At the same time, the water nozzle 3 is formed with a cooling water port 32, and the inner diameter of the metal port 42 is smaller than the inner diameter of the cooling water port 32. Therefore, the flow rate of the cooling water through the metal port 42 will be greater than the flow rate of the cooling water port 32, thereby improving the cooling and heat dissipation effect of the cooling water on the drive motor and the PCB board.

[0024] It should be noted that the circulation channel includes a first channel and a second channel. A partition component is provided between the first channel and the second channel, and the partition component is composed of a partition plate 25 located on the lower cover plate 2 and an inlay matching portion 43 located on the metal inlay 4. The partition plate 25 and the inlay matching portion 43 match each other up and down, thereby forming a stable contact sealing structure. At the same time, one end of the first channel and the second channel are connected to each other, and the other end of the first channel is connected to the circulation heat dissipation cavity 11, and the other end of the second channel is connected to the metal port 42, so that the cooling water flows from one end of the first channel to the other end into the second channel, and then moves to the other end through one end of the second channel, thereby effectively extending the length of the cooling water flow path and improving the cooling effect of the cooling water absorbing heat. Among them, one end of the first channel connected to the second channel is provided with a U-shaped diverter 24 located on the lower cover plate 2 and a matching U-shaped portion 44 located on the metal inlay 4, and the U-shaped diverter 24 and the matching U-shaped portion 44 match each other up and down, thereby forming a stable contact sealing structure. Correspondingly, the other end of the first flow channel is provided with a first flow divider 26 located on the lower cover plate 2 and a matching large division 55 located on the metal inlay 4. The first flow divider 26 and the matching large division 55 match and correspond to each other up and down, thereby forming a stable contact seal structure. The other end of the second flow channel is provided with a second flow divider 23 located on the lower cover plate 2 and a matching small division 46 located on the metal inlay 4. The second flow divider 23 and the matching small division 46 match and correspond to each other up and down, thereby forming a stable contact seal structure.

[0025] In summary, the present application provides a novel water-cooled plate for an electric control system, which cools the lower cover plate 2 through the metal inlay 4 and cools the upper cover plate 1 and the drive motor through the circulation heat dissipation cavity 11, so that the interconnected metal inlay 4 and the circulation heat dissipation cavity 11 form a circulation flow channel, thereby improving the integration while achieving the purpose of effective cooling and ensuring the normal operation of the PCB board and the capacitor module.
