[0025] See also Figure 3-4In order to quickly discharge the heat inside the energy storage inverter, the heat dissipation mechanism 4 in this embodiment includes an outlet fan 401, which discharges the hot air inside the chassis 1. Since the hot air rises, the outlet fan 401 can speed up the discharge of the hot air from the chassis 1 to prevent the hot air from staying inside the chassis 1 and continuously transferring heat with the lines and equipment. An installation opening 402 is provided on the upper surface of the mounting plate 3, and the outlet fan 401 is fixed to the mounting plate 3 through the installation opening 402. A protective net 403 is fixed to the inner side of the installation opening 402. The protective net 403 can prevent the hand from touching the outlet fan 401 to prevent hand injuries. An installation component is provided on the chassis 1.

[0026] In this example, the number of mounting openings 402 is no less than two and they are evenly distributed on the mounting plate 3, which improves the speed and efficiency of heat exhaustion. The exhaust fan 401 is located below the protective net 403, so that the protective net 403 plays a protective role.

[0027] The locating holes 405 are provided on the upper surface of the mounting plate 3, and the locating holes 405 are provided on the upper surface of the mounting plate 3. The locating holes 405 are provided on the inner surface of the locating holes 405. The locating holes 405 and the locating holes 405 can locate the mounting position of the mounting plate 3 to avoid displacement of the mounting position. The outer side of the top of the locating rod 404 is provided with a threaded groove 406. The outer side of the threaded groove 406 is threadedly connected with a fastening nut 407 to facilitate quick disassembly and assembly of the mounting plate 3. A gasket 408 is fixed on the lower surface of the fastening nut 407 to facilitate removal of the fastening nut 407. There are four locating rods 404, which are evenly distributed at the four corners of the upper surface of the mounting plate 1. The number of locating holes 405 is equal to the number of locating rods 404, and the positions correspond one to one. The inner diameter of the locating holes 405 is matched with the outer diameter of the locating rods 404, so as to improve the positioning effect of the mounting plate 3 and prevent the mounting plate 3 from loosening.

[0028] See also Figure 5 In order to improve the heat dissipation efficiency inside the storage inverter, the heat exchange mechanism 5 in this embodiment includes an air inlet pipe 501, which is fixed to the left side of the chassis 1. An air inlet 502 is provided on the left side of the chassis 1. An inlet fan 503 is fixed on the inner side of the air inlet pipe 501. The inlet fan 503 passes external cold air into the air inlet pipe 501, and the cold air is passed into the chassis 1 by the air inlet pipe 501 to cool down the lines and equipment and improve the heat dissipation efficiency. A connecting plate 504 is provided on the left side of the air inlet pipe 501, and an installation groove 505 is provided on the left side of the air inlet pipe 501. A magnetic ring 506 is fixed to the right inner wall of the installation groove 505, an iron ring 507 is fixed to the right side of the connecting plate 504, and a filter 508 is fixed on the inner side of the connecting plate 504. The magnetic ring 506 and the iron ring 507 can facilitate the removal of the connecting plate 504 and the cleaning of the filter 508.

[0029] In this example, there are two air inlet pipes 501, which are symmetrically distributed about the central axis of the chassis 1. The number of air inlets 502 is equal to the number of air inlet pipes 501, and the positions correspond one to one. In combination with the heat dissipation of the exhaust fan 401, the heat dissipation efficiency of the energy storage inverter is improved.

[0030] The working principle of the above embodiment is:

[0031] (1) First, turn on the exhaust fan 401. The exhaust fan 401 exhausts the hot air inside the chassis 1. Since hot air rises, the exhaust fan 401 can speed up the exhaust of the hot air from the chassis 1 and prevent the hot air from staying inside the chassis 1 and continuously transferring heat with the lines and equipment. The protective net 403 can prevent the hands from touching the exhaust fan 401 to prevent hand injuries. While the exhaust fan 401 is dissipating heat, turn on the inlet fan 503. The inlet fan 503 draws cold air from the outside into the air inlet duct 501. The air inlet duct 501 draws the cold air into the chassis 1 to cool the lines and equipment and improve the heat dissipation efficiency.

[0032] (2) When the air inlet fan 503 passes cold air into the chassis 1, the filter 508 will filter out the dust in the air. Over time, the dust will accumulate on the surface of the filter 508, affecting the air intake efficiency. The magnetic ring 506 and the iron ring 507 can easily remove the connecting plate 504, making it convenient to clean the filter 508. When it is necessary to remove the mounting plate 3, the fastening nut 407 is rotated to remove the fastening nut 407 from the threaded groove 406, so that the mounting plate 3 can be quickly removed. When installing again, the positioning rod 404 and the positioning hole 405 can locate the installation position of the mounting plate 3 to avoid displacement of the installation position.
