Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for energy storage cabinets, and in particular to a wind-cooled heat dissipation structure. Background Technology

[0002] With the rapid development of the energy storage industry, the energy density of energy storage cabinets is increasing, and the number of battery clusters arranged inside is also increasing. As the number of battery packs increases, the heat inside the energy storage cabinet also increases. How to solve the problem of heat dissipation inside the energy storage cabinet and maintain a reasonable and consistent battery pack temperature during operation has always been an urgent problem to be solved in the energy storage design process.

[0003] Existing energy storage cabinets typically employ a wall-mounted air conditioning unit at the rear to cool the battery packs by circulating cold air into the cabinet. However, because hot air rises and cold air sinks, after the equipment stabilizes, a large amount of cold air accumulates at the bottom of the cabinet, resulting in lower temperatures for the bottom battery packs and excessively high temperatures for the top battery packs, leading to poor temperature uniformity among the battery clusters. Utility Model Content

[0004] This utility model addresses the problems and shortcomings of existing technologies by providing a novel air-cooled heat dissipation structure.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

The battery pack is disposed in the battery rack. The wind-cooled heat dissipation structure is characterized by including an integrated air conditioning unit disposed on the rear side of the cabinet body, an exhaust air duct and an exhaust air duct disposed in the cabinet body.

[0007] The exhaust duct is horizontally arranged on the upper part of the battery rack. The exhaust duct has a first inlet and a first outlet. The first outlet is connected to the air inlet of the integrated air conditioner. The first inlet is located on the front side of the battery rack and communicates with the return air gap.

After the cold air entering the battery rack exchanges heat with the battery pack, it is drawn out by the exhaust fan and flows back to the air inlet of the integrated air conditioner through the exhaust duct.

[0009] Preferably, the exhaust duct includes a closed-connection interface, a first main body, and a second main body. The first main body and the second main body are both rectangular parallelepipeds and are respectively disposed above a row of battery packs in the battery rack. A clearance space is provided between the outer sides of the first main body and the second main body to avoid the middle support of the battery rack. The interface connects the first main body and the second main body at the middle of the rear end of the first main body and the second main body.

[0010] Preferably, the first outlet is located at the rear end of the interface portion, and there are two first inlets, which are respectively located at the front ends of the first main body portion and the second main body portion.
