Abstract

The invention provides a self-cooling energy storage cabinet, which is characterized in that a plurality of battery pack assemblies slide on guide rails through rollers and are arranged across each pair of guide rails one by one, the air draft devices of battery packs face the front side or the rear side of a box body, the plurality of battery pack assemblies are arranged in the box body side by side in a layered manner, a front door and a rear door are correspondingly installed on the front side and the rear side of the box body, the two ends of the box body are sealed through end cover plates respectively, the top and the bottom of the box body are sealed through a top cover plate and a bottom cover plate respectively, an outdoor unit of an air conditioner is installed outside the box body and close to the rear door, the indoor unit of the air conditioner is hung on a first reinforcing rib at the top of the box body, the air outlet of the indoor unit of the air conditioner is communicated with the upper end of an air conditioner air guide pipe, the air conditioner air guide pipe is vertically arranged in the box body, the outlet holes of the air conditioner air guide pipe directly face the inlet holes of battery packs one by one, and the positive and negative ends of the power supply of the air conditioner are connected with positive and negative ends of the first output of acontroller. The self-cooling energy storage cabinet is simple in structure and convenient to mount and dismount, and the cooling or heating efficiency of the battery pack can be improved.

Description

technical field [0001] The invention relates to a self-cooling energy storage cabinet. Background technique [0002] With the advancement of science and technology and the continuous development of energy storage technology, the application fields of energy storage products are becoming more and more extensive, and in some application fields with harsh environmental conditions, such as deserts, Gobi deserts and other places with large temperature differences between day and night and high dust-proof requirements , the commonly used lithium battery is difficult to work normally due to its own battery characteristics. At this time, it is necessary to create a suitable working environment for the battery by adding external accessories to the battery pack, so as to maximize the performance of the battery and prolong the service life of the battery. . At present, most of the cooling and heating systems of battery packs are liquid flow systems, which are complex in structure, hig...
