Claims

1. A heat dissipation structure of an energy storage cabinet battery pack, the energy storage cabinet comprising a cabinet body and a battery rack arranged in the cabinet body, characterized in that, A return air gap is reserved between the front side of the battery rack and the cabinet, and air inlet gaps are reserved between the left, right and rear sides of the battery rack and the cabinet. The return air gap and the air inlet gap are separated and not connected. The battery pack is set in the battery rack. The heat dissipation structure includes an integrated air conditioner set on the front side of the cabinet and a heat dissipation duct set in the cabinet. The heat dissipation duct includes a main air duct and an exhaust air duct. The main air duct is horizontally arranged on the upper part of the battery rack. An air inlet is provided on the front side of the main air duct, and a left air outlet, a right air outlet, and a rear air outlet are provided on the left, right, and rear sides of the main air duct, respectively. The left air outlet, the right air outlet, and the rear air outlet are all connected to the air inlet gap. The exhaust duct is located in front of the main duct. The exhaust duct has an inlet and an outlet. The inlet is connected to the air outlet of the integrated air conditioner, and the outlet is connected to the air inlet of the main duct. The battery rack is multi-layered, and each layer of the battery rack is equipped with a battery pack. The battery pack has a rear-open outer shell and a front panel. Air inlets are provided on the left and right sides of the outer shell, and an exhaust fan is provided on the front panel. The cold air blown out of the air outlet of the air conditioner enters the main air duct through the exhaust duct. The cold air in the main air duct enters the battery pack through the left air outlet, the right air outlet and the rear air outlet through the air inlet gap, undergoes heat exchange, and is then drawn out by the exhaust fan to the return air gap, flowing back to the air inlet of the air conditioner.

2. The energy storage tank battery pack heat sink structure of claim 1, wherein, The cabinet has an openable front door, and the integrated air conditioner is installed on the front door. The exhaust duct is tilted downwards and forwards, so that the inlet is directly opposite the air outlet of the integrated air conditioner. When the front door is closed, the inlet is aligned with the air outlet of the integrated air conditioner.

3. The energy storage tank battery pack heat sink structure of claim 2, wherein, A sealing strip is provided at the edge of the entrance. When the front cabinet door is closed, the sealing strip seals the connection between the entrance and the air outlet of the integrated air conditioner.

4. The energy storage tank battery pack heat sink structure of claim 1, wherein, The left and right walls of the main air duct extend downwards and bend, so that the left and right air outlets are both positioned directly downwards.

5. The energy storage tank battery pack heat sink structure of claim 4, wherein, Both the left and right air outlets are equipped with downward-extending air guide plates to guide the cold air downwards.
