Background

The electric automobile is an effective way to solve the energy and pollution problems faced by automobile transportation, and a hybrid power or pure electric automobile using electric energy as a power source represents the future development direction of the automobile industry. At present, energy storage equipment of an electric automobile is mainly a lithium ion power battery pack, and the lithium ion battery pack has the defects of environmental adaptability, service life and energy density characteristics, so that the further popularization and application of the lithium ion battery pack are limited. In order to solve the above problems, the prior art has a battery cooling system added in the lithium ion battery pack to improve the charging performance, the discharging performance, the service life and the safety of the battery system. In a battery water cooling system, a cooling plate is used to transfer heat from a coolant. The inner wall of the cooling plate in the prior art is flat, which is not beneficial to the heat dissipation of the cooling plate and cooling liquid. Therefore, it is necessary to design a water-cooling plate structure of an automobile power battery to increase the heat conduction effect of the cooling plate.

Chinese patent application publication No. CN207690852U, the publication date is 2018, 08 months 03 days, entitled "a power battery water-cooling structure", discloses a power battery water-cooling structure applied to the technical field of power batteries in the new energy field, battery body (1) of power battery water-cooling structure include a plurality of battery modules (4), set up the clearance portion between every two adjacent battery modules (4), press from both sides water-cooling plate (2) of a perpendicular arrangement in every clearance portion, the one end of every water-cooling plate (2) is through the one end connection of a module support (3) and another adjacent water-cooling plate (2), the other end of every water-cooling plate (2) is through the other end connection of another module support (3) and another adjacent water-cooling plate (2). The water-cooling structure of the battery still has the above-mentioned problems.

Disclosure of Invention

The utility model discloses an overcome the not enough problem of water-cooling board radiating effect among the prior art, provide an automobile power battery water-cooling board structure, increase the area of contact of coolant liquid and water-cooling board, make more heats on the heat conduction material can be taken away to the water-cooling board, make the cooling that electric core can be faster.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides an automobile power battery water-cooling board structure, includes the water-cooling board of closed shape, is equipped with the inner chamber in the water-cooling board, is equipped with the rib that a plurality of was arranged in proper order on the inner wall of inner chamber.

Among the above-mentioned technical scheme, increase the rib in the water-cooling board, can increase the area of contact of coolant liquid and water-cooling board, make more heats on the water-cooling board can take away (or transmit) the heat conduction material, make the more fast cooling (or the intensification) of electric core ability.

Preferably, the longitudinal direction of the ribs is perpendicular to the water flow direction.

Preferably, the longitudinal direction of the ribs is parallel to the direction of water flow.

Preferably, the inner cavity is provided with a plurality of supporting blocks, and the supporting blocks are fixed with the inner walls of the inner cavities at two ends. The structure can increase the structural strength of the water cooling plate.

Preferably, the supporting blocks are divided into a plurality of groups of supporting groups, each group of supporting groups are arranged along the direction of water flow, and each group of supporting groups comprises a plurality of supporting blocks. The structure can further increase the structural strength of water-cooling board, can play the vortex effect again simultaneously, increases the radiating effect.

Preferably, the supporting blocks in the supporting groups are staggered with the supporting blocks in the adjacent supporting groups. The structure can further increase the vortex effect, and then increase the radiating effect.
