Its functions include regulating and managing the charging and discharging process of the battery system, frequency adjustment and power balance of the power grid, etc. There are many heat-generating electrical appliances in the energy storage inverter, which will generate a lot of heat during use. Especially in a closed box, the heat is often not well dissipated. Therefore, a heat dissipation device for the energy storage inverter is needed.

The sleeve 8 is moved on the movable shaft 4 by manually pushing and pulling the sleeve 8. The movement of the sleeve 8 drives the first push-pull rod 9 and the second push-pull rod 10 to move. The movement of the first push-pull rod 9 and the second push-pull rod 10 drives the first support 11 and the second support 12 to move synchronously. The movement of the first support 11 and the second support 12 pushes and pulls the first action block 6 and the second action block 7. Due to the connection mode between the first action block 6 and the second action block 7 and the rotating block 5, the first action block 6 and the second action block 7 always maintain opposite or reverse movement. The rotating block 5 is squeezed and pulled by the first action block 6 and the second action block 7, so that it rotates. The rotation of the rotating block 5 causes the vertical rod 13 to rotate synchronously. The rotation of the vertical rod 13 causes the heat dissipation blade 14 to rotate synchronously, thereby controlling the angle of the heat dissipation blade 14 and adjusting the heat dissipation effect of the heat dissipation device to avoid the heat dissipation effect being inconsistent with the heat generation of the energy storage inverter, resulting in poor heat dissipation effect or waste of resources.

[0025] A filter plate 19 is installed on the seal 18, and a plurality of circular holes are opened on the filter plate 19. A fixed heat sink 16 is installed on the top of the inverter housing 1, and a plurality of strip holes are opened on the fixed heat sink 16. A drive shaft 20 is connected to the output end of the drive motor 2, and a fan blade 21 is installed on the drive shaft 20. A support frame 17 is installed on the inverter housing 1, and the drive motor 2 is mounted on the support frame 17. The drive motor 2 is driven to make the drive shaft 20 drive the fan blade 21 to rotate, thereby dissipating heat for the energy storage inverter. The filter plate 19 filters dust to prevent dust from entering the energy storage inverter and causing the energy storage inverter to malfunction.

[0026] The other end of the inverter housing 1 is provided with a seal 18, on which an "L"-shaped block 22 is provided, on which a telescopic rod 24 is provided, on which a compression spring 23 is coaxially provided, and the telescopic rod 24 is connected with a cross bar 25, which is connected with a convex block 26. By pressing the cross bar 25, the telescopic rod 24 is compressed, and the telescopic rod 24 squeezes the compression spring 23 during the compression process. After the cross bar 25 is pressed to an appropriate position, the convex block originally stuck on the carrier 17 is released. The block 26 leaves the carrier 17, completing the disassembly of the carrier 17, thereby cleaning the dust on the filter plate 19 and the fan blades 21. When the carrier 17 needs to be installed, the cross bar 25 is pressed again to make the telescopic rod 24 squeeze the compression spring 23. After the protrusion 26 reaches the fitting position on the carrier 17, stop applying pressure to the cross bar 25, so that the compression spring 23 pushes the telescopic rod 24 to reset, so that the protrusion 26 is stuck on the carrier 17, completing the installation of the carrier 17.

A telescopic rod 24 is arranged on the "L"-shaped block 22, and a compression spring 23 is coaxially arranged on the telescopic rod 24. The telescopic rod 24 is connected to a cross bar 25, and the cross bar 25 is connected to a protrusion 26. The heat dissipation blade 14 is rotated by pushing and pulling the sleeve 8, so that the heat dissipation device can be adjusted in terms of efficiency. By pressing the cross bar 25, the carrier frame 17 is removed from the protrusion 26 for cleaning dust.
