Problems solved by technology
[0006] The technical problem solved by the present invention is to provide a two-way channel battery cooling plate and a liquid-cooled power battery module. The cooling plate cooperates with the liquid cooling system to further improve the temperature consistency of the battery module and prolong the cycle life of the power battery. It can overcome the problem of weak temperature difference control ability of the existing battery cooling plate and the weak cooling effect on the power battery, and can effectively control the battery module to work within the normal operating temperature range, improve the consistency of the battery temperature, and effectively improve the battery temperature.

Abstract
The invention discloses a bidirectional flow channel battery cooling plate and a liquid cooling power battery module, the cooling plate comprises a first flow channel and a second flow channel which are arranged in parallel, the first flow channel and the second flow channel are both S-shaped flow channels, the first flow channel and the second flow channel are arranged at an equal interval, and the flow directions of liquid cooling media of the first flow channel and the second flow channel are opposite. The invention further discloses the power battery module with the liquid cooling assembly, the power battery module comprises battery cells, insulating heat-conducting fins, cooling plates, busbars and a fixing sleeve, the battery cells are arranged in parallel at certain intervals, the busbars are buckled at tab positions, the outer sides of the busbars are limited and fixed through the fixing sleeve, and the insulating heat-conducting fins and the cooling plates are sequentially arranged on two sides. According to the invention, the temperature difference in the battery module is further reduced while the temperature of the battery is controlled within a reasonable range.
Description
technical field [0001] The invention relates to the technical field of new energy power batteries, in particular to a bidirectional channel battery cooling plate and a liquid-cooled power battery module. Background technique [0002] Lithium-ion batteries have become the first choice for clean energy to replace fossil fuels due to their high monomer voltage, large specific energy, wide operating temperature range, and long service life. They are widely used in new energy electric vehicles as power batteries. [0003] The power battery pack is the core component of electric vehicles. When the power battery pack is running normally, the battery is constantly charging and discharging, which will generate heat. When the heat dissipation of the battery is not timely, the temperature of the battery will rise. When the temperature exceeds a certain A critical value will cause damage to the service life of the battery. At the same time, high temperature will cause side reactions ins...
