Referring to fig. 1 to 4, according to an energy storage inverter 100 in an embodiment of the present utility model, the energy storage inverter 100 may include a heat sink 10, a control board 20, and a housing 30.

Specifically, the control board 20 is laminated on the heat sink 10, and the control board 20 is covered by the case 30 so that the control board 20 can be isolated from the external environment to avoid the control board 20 from being disturbed; the control board 20 may have a heat source, which may be a chip or other electronic component capable of generating heat, and when the energy storage inverter 100 works, the heat source generates heat, and at this time, a local area on the first side of the heat dissipation board 11 may be provided with the fin group 12, where the local area may correspond to the heat source on the control board 20, in other words, the heat generated by the heat source of the control board 20 may be conducted to the heat dissipation board 11 and may be conducted from the heat dissipation board 11 to the fin group 12, and at least one heat dissipation fin 121 in the fin group 12 dissipates the heat to the external environment, so as to implement targeted heat dissipation for the control board 20, so that the energy storage inverter 100 may work in a suitable temperature range, improve the working efficiency of the energy storage inverter 100, and save the manufacturing cost.

Therefore, according to the energy storage inverter 100 in the embodiment of the present utility model, by providing the fin group 12 in the partial region of the heat dissipation plate 11, the heat dissipation efficiency of the energy storage inverter 100 can be improved, while the provision of the fin group 12 in the partial region can save the manufacturing cost of the energy storage inverter 100 compared to the provision of the fin group 12 in the entire region.

Of course, according to practical situations, a heat dissipation area, a fan and other heat transfer elements may be disposed on the control board 20, and the control board 20 may have a heat dissipation area 21, and electronic elements may be disposed in the heat dissipation area 21; when the energy storage inverter 100 works, the electronic components of the heat generating area 21 can generate heat, at this time, the heat generated by the heat generating area 21 can be blown to the heat dissipating area by a heat transfer element such as a fan, and the fin group 12 of the partial area of the first side of the heat dissipating plate 11 can correspond to the heat dissipating area, in other words, the heat of the heat dissipating area can be sequentially conducted to the heat dissipating plate 11 and the fin group 12, and finally, the heat can be dissipated to the external environment by at least one heat dissipating fin 121 of the fin group 12;

Specifically, when the energy storage inverter 100 operates, the first heat generating area 211 and the second heat generating area 212 may generate heat respectively, and the heat generation amount of the first heat generating area 211 is greater than that of the second heat generating area 212, so that on the first side of the heat dissipation plate 11, the heat dissipation fins 121 may be disposed in a targeted manner, in other words, on the first side of the heat dissipation plate 11, a relatively large number of heat dissipation fins 121 in a unit area may be disposed to correspond to the first heat generating area 211, and at the same time, a relatively small number of heat dissipation fins 121 in a unit area may be disposed to correspond to the second heat generating area 212, i.e., the number of fins in a unit area corresponding to the first heat generating area 211 may be greater than that of fins in a unit area corresponding to the second heat generating area 212.
