Water-cooling device for lithium-ion power battery grouping

Abstract

The invention relates to a water-cooling device for lithium-ion power battery grouping, which comprises a battery module, a battery module protection cover and a battery bottom cover. The battery module is composed of a plurality of battery cooling clamp plates and a plurality of single batteries, wherein a groove is respectively arranged on each battery cooling clamp plate, the bottom of each groove is formed by two parallel cooling sheets at intervals, and each single battery is arranged in each groove of each battery cooling clamp plate. The battery module protection cover, the battery module and the battery bottom cover are sequentially connected through a bolt connection rod, a total water inlet and a total water outlet are symmetrically arranged at the top end of the battery module protection cover, a water inlet passage opening and a water outlet passage opening are respectively arranged on each battery cooling clamp plate at positions corresponding to the total water inlet and the total water outlet, water inlet holes are arranged in the water inlet passage openings, and water outlet holes are arranged in the water outlet passage openings. The water-cooling device is convenient to manufacture, remarkable in radiating effect, safe and reliable, achieves heat balanced management during water cooling, and effectively ensures safety and reliability of lithium-ion power batteries in use.

Description

technical field [0001] The invention relates to a battery water cooling method and a device thereof, in particular to a water cooling device for grouping lithium-ion power batteries. Background technique [0002] The development theme of today's world is safety, environmental protection, green energy saving, how to meet the demand of automobiles for oil, and how to reduce the damage of automobiles to the environment are issues related to the energy security of the entire country. The traditional power comes from the combustion process of gasoline in the engine, which not only generates a lot of heat, but also produces a lot of poisonous and harmful gases, which is very inconsistent with the theme of environmental protection in today's world. As a result, lithium-ion power batteries have emerged as the times require, and they will receive major attention as the mainstream of the power battery market in the future. Lithium-ion power batteries have the advantages of stable vol...
