Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to an air-cooled battery cabinet. Background Technology

[0002] Currently, battery cabinets are widely used in energy storage systems, communication base stations, and other fields. However, with the increasing number of battery packs, the compact space inside the cabinet has led to increasingly prominent heat dissipation problems. Traditional heat dissipation methods mainly rely on natural convection. Due to the dense arrangement of battery packs, the airflow distribution is uneven, resulting in severe local heat accumulation, which affects battery performance and lifespan. In addition, the existing heat dissipation structure design is simple and cannot meet the heat dissipation requirements of high-power, high-density battery packs, leading to excessively high battery temperatures and even the risk of thermal runaway. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defect of poor heat dissipation effect of the existing battery cabinet, so as to provide an air-cooled battery cabinet with good heat dissipation effect.

[0004] Therefore, this utility model provides an air-cooled battery cabinet, including a cabinet body and an air cooler. The cabinet body has multiple rows of battery packs and air guide channels on both sides of the battery packs. Each row of battery packs is spaced apart along the height of the cabinet body. The air cooler is located at the front door panel of the cabinet body and has an air inlet chamber and an air outlet chamber located inside the cabinet body and arranged vertically. The air inlet chamber has multiple air inlets located on its upper side and a sealing ring is installed at the air inlet. The air outlet chamber has an air outlet located at its bottom, and the air outlet is corresponding to the lowermost battery pack in the cabinet body. Multiple air guide chambers are located at the top of each row of battery packs and have air guide ports opposite to the air inlets. The air guide chambers are connected to the air guide channels. When the front door panel is closed, the sealing ring is in contact with and abuts against the front end face of the air guide port.

[0005] The cabinet includes support columns and support plates spaced apart along the height of the support columns, the support plates being used to mount the battery pack.

[0006] The support plate is L-shaped, with a horizontal plate and a vertical plate. The support column is provided with a hanging hole, and the vertical plate is provided with a hook that abuts against the hanging hole.

[0007] The rear end face of the horizontal plate is provided with a blocking part that is bent and connected to it for abutting against the battery pack.

[0008] The vertical plate has a through hole, and the support column has a threaded hole opposite to the through hole. After the bolt passes through the through hole and the threaded hole in sequence, the vertical plate is fixed to the support column.

[0009] The technical solution of this utility model has the following advantages:

[0010] 1. The air-cooled battery cabinet provided by this utility model, by setting up multiple rows of battery packs and two side guide channels, combined with the upper and lower air inlet and outlet chambers of the air cooler, allows cold air to be distributed to each layer of batteries through the air guide chambers and guide channels, forming an orderly airflow path, avoiding short-circuit circulation, ensuring the temperature uniformity of each battery pack, and avoiding local overheating; in addition, the air inlet is equipped with a sealing ring, which fits tightly with the air guide when the front door is closed to prevent cold air leakage, ensuring that all airflow is used for battery cooling, reducing the energy consumption of the air cooler, and improving energy efficiency.

[0011] 2. The air-cooled battery cabinet provided by this utility model uses hooks and hanging holes to match the support plate, and then fixes it to the support column with bolts, which makes the assembly quick and convenient.

[0012] 3. The air-cooled battery cabinet provided by this utility model has a blocking part that can hold the battery pack in place to prevent it from sliding back and forth during operation or transportation, thereby improving safety. In addition, the blocking part can be adjusted to bend at an angle according to different battery pack sizes to accommodate various battery specifications and improve versatility.
