[0007] The heat sink is made of copper or aluminum and has a plurality of through holes on its outer side, which facilitates air flow between the heat sinks and improves the heat dissipation effect.

[0008] The heat conductive sheet is arranged on the bottom side of the mounting frame, and the upper surface of the heat conductive sheet is in contact with a plurality of heat sinks. By arranging the heat conductive sheet, the other side of the heat conductive sheet is in contact with the electronic components of the energy storage inverter, thereby conducting the heat generated during the use of the components to the plurality of heat sinks.
