The module sheet metal part is a structure with upper and lower openings and four closed sides.

[0027] Example 3

[0028] Combined with Figure 2 and 3 Compared with any one of the technical solutions in Examples 1-3, the heat dissipation structure of the energy storage converter of this embodiment can be improved as follows: the first support beam 9 is provided with a first air duct 901 connected to the first air duct 13, the first support beam 9 is provided with a second air duct 902 connected to the second sheet metal heat dissipation area, and the first air duct 901 and the second air duct 902 are staggered.

[0030] Combined with Figure 3 In the heat dissipation structure of the energy storage converter of this embodiment, the second air duct 902 is provided with a plurality of partitions 9021. The provision of the partitions makes the ventilation area of ​​the second air duct 902 smaller than that of the first air duct 901, because the heat sink located in the module sheet metal has a large heat generation, and its heat dissipation needs to be arranged first.

The vents 13 further increase the heat dissipation effect in the box 1. A fan is also provided inside the box corresponding to the air outlet 15 to dissipate the heat of the reactor in the box, because the heat dissipation of the reactor cannot be met through the first air duct or the second air duct or the vent.

[0037] Example 8

[0038] Combined with Figure 3 , the heat dissipation structure of the energy storage converter of this embodiment can be improved as follows compared with any one of the technical solutions of embodiments 1-7: a plurality of air holes 903 are also provided at intervals on the side of the first support beam 9 close to the rear door 104. The rear door is equipped with a capacitor pool. In the energy storage converter, the capacitor pool is also a group of devices with relatively large heat generation. The heat dissipation requirements of the capacitor pool cannot be met through the first air duct 13 and the second air duct 14. Therefore, the air holes 903 are opened on the first support beam 9, so that when the exhaust fan 6 is working, the fan can quickly take away the hot air on the capacitor pool side through the air holes 903 to achieve a cooling effect.
