[0001] This utility model relates to the field of energy storage device technology, and more particularly to a household energy storage device with high heat dissipation. Background Technology

[0002] Energy storage devices are devices that can convert electrical energy into other forms of energy for storage and convert it back into electrical energy when needed. They can achieve electrical energy storage through various technologies, such as battery storage, supercapacitor storage, and mechanical storage. These technologies enable energy storage devices to play a vital role in power systems, especially in renewable energy fields such as solar and wind power generation.

[0003] When an energy storage device is in use, the battery cells will generate heat. Because the inside of the energy storage device is relatively sealed, heat will accumulate inside the chassis, affecting the service life of the energy storage device. The heat dissipation effect of existing energy storage devices is still not ideal and needs to be improved. Summary of the Invention

The heat dissipation module includes a thermally conductive adhesive block, a thermoelectric cooling chip, a heat sink, and a cooling fan. Through holes corresponding to the cells are distributed through the thermally conductive adhesive block, and the cells are disposed within these through holes. Heat dissipation holes are provided on one side wall of the chassis, and a window is provided on the top of the battery compartment. The thermoelectric cooling chip is disposed on the window, with its cold end in close contact with the top surface of the thermally conductive adhesive block. A first thermally conductive contact surface is provided on the heat sink, which is in close contact with the hot end of the thermoelectric cooling chip. The cooling fan is installed on the inner wall of the chassis and can dissipate the heat emitted from the heat sink through the heat dissipation holes outside the chassis. The thermoelectric cooling chip and the cooling fan are both electrically connected to the control circuit.

[0006] Preferably, the chassis includes a first housing and a second housing that are paired together. The inner walls of the first housing and the second housing are respectively provided with square compartments. One side wall of the square compartment is provided with a notch. The two square compartments are joined together to form a battery compartment. The two notches are joined together to form a window.

[0009] Preferably, an air inlet is provided on the other side wall of the chassis.

[0010] The beneficial effects of this utility model are as follows: This utility model provides a household energy storage device with high heat dissipation. When the energy storage device is working, the heat generated by the battery cell can be conducted to the thermally conductive adhesive block. When the semiconductor cooling chip is working, its cold end will absorb heat from the thermally conductive adhesive block, ensuring that the thermally conductive adhesive block is maintained at a low temperature and ensuring that the battery cell can dissipate heat quickly.
