Abstract

The invention discloses an immersed liquid cooling battery pack. The immersed liquid cooling battery pack comprises a shell, at least one battery pack is arranged in the shell, and each battery pack comprises a plurality of battery cells arranged at intervals in the first direction; a liquid inlet cavity and a liquid outlet cavity are formed in the two sides of the battery pack in the second direction, and the second direction is perpendicular to the first direction; a liquid inlet is formed in one of the two ends, in the first direction, of the liquid inlet cavity, and a liquid outlet is formed in the end, different from the liquid inlet, of the two ends, in the first direction, of the liquid outlet cavity, so that cooling liquid enters the liquid inlet cavity from the liquid inlet, flowsinto the liquid outlet cavity after flowing through the battery pack and flows out from the liquid outlet; and a flow equalizing plate is arranged between the liquid inlet cavity and the battery pack, the flow equalizing plate is arranged in the first direction, a liquid through hole is formed in the flow equalizing plate, and a plurality of flow deflectors which are arranged at intervals in thesecond direction are arranged at the liquid through hole. The immersed liquid cooling battery pack provided by the invention is high in heating/cooling efficiency, good in uniformity and simple in structure.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a submerged liquid-cooled battery pack. Background technique [0002] In recent years, with the rapid growth of the new energy vehicle market, technologies related to electric vehicles have also developed rapidly. The power battery is one of the core components of an electric vehicle, and its performance is directly related to the working condition of the vehicle. [0003] When the battery is working, a violent chemical reaction occurs inside to provide electric energy. During the charging and discharging process, a large amount of heat will be generated, which will cause the temperature of the battery to rise, and the temperature of the battery will directly affect the safety of the battery, the charging and discharging capacity and efficiency, and the cycle life. And other performance, and then affect the working performance of the vehicle. The optimal operating temperature...
