Description

Technical Field

[0001] The utility model relates to the technical field of battery pack thermal management systems, in particular to a novel water cooling plate structure. Background Art

[0002] Power batteries are an indispensable source of power output in today's new energy vehicles. Power batteries are very sensitive to temperature. During use, their temperature will gradually rise. When the temperature is too high, the battery will suffer thermal runaway.

[0003] Therefore, it is crucial to cool the battery pack. As an important component of liquid cooling, the water cooling plate mainly ensures that its surface is in full contact with the surface of the battery. The flow of fluid inside the water cooling plate takes away the heat of the battery for heat exchange, thereby reducing the battery temperature.

[0004] As the most important part, the design and process of the water-cooling plate have strict requirements on heat dissipation effect, processing and manufacturing, mass production cost and production efficiency. In the prior art, in order to improve the heat dissipation efficiency, the water-cooling plate is made relatively thin. In practical applications, the heat that can be absorbed by a too thin water-cooling plate is limited. However, the process from the fluid entering the water-cooling plate to flowing out of the water-cooling plate is fleeting. The water-cooling plate does not absorb the heat of the fluid to the maximum extent, resulting in a lot of heat remaining in the fluid flowing out of the water-cooling plate. This situation can be clearly seen in the heat dissipation data of long-term use. The heat dissipation efficiency has decreased. Therefore, the applicant believes that the structure of the water-cooling plate should be improved in this regard. Utility Model Content

[0005] The main purpose of the utility model is to propose a novel water cooling plate structure, aiming to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model proposes a novel water-cooling plate structure, including a long strip-shaped water-cooling plate body, wherein a water inlet cavity with a water inlet and a water outlet cavity with a water outlet are provided inside the water-cooling plate body, wherein the water inlet cavity and the water outlet cavity are connected, and the fluid can enter the water inlet cavity through the water inlet, flow to the water outlet cavity and then flow out from the water outlet, and the top wall of the water-cooling plate body is provided with a plurality of thickened portions at intervals along the length direction of the water-cooling plate body, and the width of the thickened portions is adapted to the width of the water-cooling plate body.

[0007] The technical solution of the utility model is provided with a plurality of thickened parts on the top wall of the water-cooling plate body, and the plurality of thickened parts are spaced apart along the length direction of the water-cooling plate body, and the width of the thickened parts is adapted to the width of the water-cooling plate body. In the process that the fluid carrying heat enters the water-cooling plate body and then flows out, the thickened parts increase the absorption of the heat of the fluid by the water-cooling plate body, and reduce the heat of the water flowing out of the water-cooling plate body. The overall thin and thick water-cooling plate body can increase the absorbed heat and can also dissipate the absorbed heat in time, so that good heat dissipation efficiency can be maintained even after long-term use. The overall structure is simple and the production cost is low. BRIEF DESCRIPTION OF THE DRAWINGS
