The sealing assembly includes a top plate conductive silicone 5 inside the upper end of the shell and a pressure relief valve 12 installed on the inductor board PCB support plate 9. The fan assembly includes a fan mounting plate 20 connected to the shell, on which a fan 4 and a fan small board PCB 21 are installed.

[0031] The housing includes a bottom plate 1, a rear plate 3, a top plate 6 and side panels 18 that are connected by bolts. Specifically, heat dissipation holes are provided on the opposite surfaces of the side panels 18 and the bottom plate 1.

[0032] The top plate conductive silicone rubber 5 is installed at the lower end of the top plate 6. The top plate 6 of the energy storage converter controller is in surface contact with the assembly surface of the side panel 18. The top plate conductive silicone rubber 5 is selected for sealing. First, the contact area is larger and the sealing effect is better.

Specifically, the inductor plate PCB14 and the capacitor plate PCB17 of the energy storage current converter controller are a single piece of PCB, which reduces the electrical connection between the circuit boards and improves reliability.

[0036] During the specific implementation of the present invention, a guide plate 2 is installed at the lower end of the capacitor plate PCB support plate 11. The energy storage inverter controller adds the guide plate 2 so that the fan air volume is evenly distributed to each section of the heat sink, which is beneficial to average the temperature of the heat sink and improve the overall heat dissipation efficiency.

The upper part is sealed for protection, and the lower part is cooled by air ducts. In addition, a layer of AB potting glue is sprayed on the upper part, so the overall protection level is further improved, and the reliability and service life of the product are greatly improved.
