Novel energy storage container heat management system

Abstract

The invention provides a novel heat management system for an energy storage container, and the system is used for providing a heat dissipation function for an electricity box used as electricity storage equipment in the container; an electricity storage module is formed by a plurality of battery cells in the electricity box, and the heat management system comprises a water cooling pipeline arranged in the electricity box; the water cooling pipeline at the bottom of the electric box forms a first heat dissipation structure for dissipating heat of the bottom surface part of the battery cell; the water cooling pipelines between the battery cells in the electric box are vertically arranged to form a second heat dissipation structure for dissipating heat of the side wall parts of the battery cells; the water cooling pipeline in the second heat dissipation structure further extends to the busbar of the battery cell to form a third heat dissipation structure for dissipating heat of the busbar; the heat management system further comprises a temperature control device installed at the top of a cooling water path pipe network in the container, and the temperature control device adjusts the temperature and humidity of air in the container so as to prevent condensed water from being formed at a water path pipeline. According to the invention, the heat of the battery cell in the energy storage electric box can be efficiently dissipated, and meanwhile, a heat shielding layer is formed by the water-cooling pipeline network surrounding the battery cell.

Description

technical field [0001] The invention relates to the technical field of heat dissipation, in particular to a novel energy storage container heat management system. Background technique [0002] With the promotion and application of new energy sources such as solar energy and wind energy, energy storage technology has also developed. Lithium batteries have high energy, long service life, high rated voltage, high power tolerance, low self-discharge rate, and light weight. , green and environmental protection, and basically no water consumption in production, it has gradually become the mainstream product of energy storage. [0003] Under normal circumstances, a thermal management system is arranged inside the energy storage container to dissipate the heat of the battery cells. Traditionally, the following method is adopted: a water-cooled plate is placed at the bottom to dissipate heat from the bottom of the battery cells. [0004] However, the traditional method has the follo...
