Abstract

The invention relates to the technical field of energy storage equipment, and particularly relates to a battery PACK cooling assembly, an energy storage container and a cooling method. The battery PACK cooling assembly makes the cold air flow into a first air supply cavity and flows into a first air collection cavity from a gap between battery PACKs to cool the battery PACKs. The battery PACK cooling assembly has the effects of ordered flow of a wind field, small temperature difference in the box and stable cooling effect. The energy storage container comprises at least two battery PACK cooling assemblies. The first air supply cavities of two adjacent battery PACK cooling assemblies are communicated or the first air collection cavities of the two adjacent battery PACK cooling assemblies are communicated, so that the unit design volume of the energy storage container is reduced, and the occupied area of the energy storage container is also reduced. According to the cooling method, cooling is achieved by making the cold air pass through the space between the two adjacent battery PACKs, so that the cooling effect is good; and the first air collection cavity and the first air supply cavity separate the two sides of a battery rack, the air field flows orderly, and the temperature difference in the energy storage container is small.

Description

technical field [0001] The invention relates to the technical field of energy storage equipment, in particular to a battery PACK cooling assembly, an energy storage container and a cooling method. Background technique [0002] Under the background of the exponential growth of the new energy industry, lithium battery energy storage is also becoming more and more mature. After the battery PACK is transferred into the energy storage container, the energy storage container needs to provide a constant environment to ensure the temperature difference between the batteries. There are two main factors to solve the temperature difference: air duct and circulating air volume. At present, most energy storage containers are cooled in different areas inside the container, ventilated and ventilated for cooling, etc. The temperature difference in the container is large, and the wind field is messy. Contents of the invention [0003] The purpose of the present invention is to at least so...
