Description

Technical Field

[0001] The utility model relates to the technical field of air-cooled plug-in boxes, in particular to an air-cooled battery plug-in box for energy storage. Background Art

[0002] Air-cooled plug-in boxes are widely used in the field of electronic equipment structure. Their role is to use standardized plug-in boxes to realize the modularization of electronic equipment. They are widely used in the communication industry, ship equipment, and industrial and commercial energy storage fields and have generated corresponding safety production standards.

[0003] Battery heat dissipation is a problem that has always existed with the development of the battery industry. Controlling the temperature of the battery cell while ensuring sufficient charge and discharge rates and capacity is an urgent issue to be solved in the energy storage field. There are two heat dissipation methods in the energy storage industry: air cooling and liquid cooling. Air cooling is to force the battery to cool through air. During design, the battery pack is blown by air through air conditioners or fans to dissipate heat. Since the cold air of a fully sealed plug-in box can only blow to the surface of the plug-in box, the heat dissipation effect is limited. High-power air conditioners and fans are required to meet the heat dissipation requirements of the battery cell, which increases the power consumption and overall cost of the system.

[0004] In addition, in order to meet the requirements of energy density, there are usually restrictions on the size of the plug-in box during design, making the layout inside the plug-in box compact. This leads to limited space for air duct layout in the plug-in box, making it difficult to meet the heat dissipation requirements.

[0005] In order to meet the energy density requirements, the existing air-cooled plug-in box has a compact stacking structure between the battery cells, which will cause uneven heat dissipation of the battery module, thereby affecting the use efficiency of the battery module. Summary of the invention

[0006] According to the problems raised in the background technology, the utility model provides an air-cooled battery plug-in box for energy storage to solve the problems. The utility model will be further described below.
