Battery liquid cooling plate structure and automobile battery

Abstract

The invention relates to a battery liquid cooling plate structure and an automobile battery. The battery liquid cooling plate structure comprises a liquid cooling plate main body and a liquid inlet and outlet structure. The liquid cooling plate main body comprises an upper cooling plate and a lower cooling plate arranged side by side up and down, a plurality of partition plate ribs arranged between the upper cooling plate and the lower cooling plate at intervals, and a cooling cavity between the upper cooling plate and the lower cooling plate is divided into a plurality of cooling flow channels by the plurality of partition plate ribs. The liquid inlet and outlet structure comprises a liquid inlet plate structure and a liquid outlet plate structure which are arranged at the two ends of theliquid cooling plate body respectively, a liquid inlet cavity communicated with one end of the cooling flow channel is formed in the liquid inlet plate structure, and a liquid outlet cavity communicated with the other end of the cooling flow channel is formed in the liquid outlet plate structure; a liquid inlet head communicated with the liquid inlet cavity is arranged on the liquid inlet plate structure, and a liquid outlet head communicated with the liquid outlet cavity is arranged on the liquid outlet plate structure. According to the present invention, the processing technology of the battery liquid cooling plate is simplified, so that the liquid cooling plate meets the design requirement of light weight, and meanwhile, the cooling and heat dissipation performance of the liquid cooling plate is improved.

Description

technical field [0001] The invention relates to the technical field of battery cooling, in particular to a battery liquid cold plate structure and an automobile battery. Background technique [0002] Batteries are the core components of power vehicles. In terms of the manufacturing cost of pure electric vehicles, batteries also account for the highest proportion. The industry believes that the biggest problems of electric vehicles at present are price and pure electric cruising range. The main solutions to these two problems In addition to improving the energy density of the battery pack, there are also standardization and lightweighting. Standardization refers to the standardization of core components such as battery modules and motors, while lightweighting refers to reducing the weight of the vehicle without reducing the safety factor of the vehicle. Weight reduction for large components. This is the main direction of the development of electric vehicle technology in the ...

Problems solved by technology

[0004] In the related art, the battery liquid cold plate generally includes a bottom plate, an upper plate and a plurality of harmonica tubes, and the harmonica tubes are fixed side by side on the bottom plate; but the battery liquid cold plate has the following problems: 1. The overall thickness angle of the battery liquid cold plate , the quality is heavy; 2. The battery is installed on the upper plate, and the cooling liquid enters the flow channel in the upper plate from the inlet port on the upper plate, and then flows into each harmonica tube, and the harmonica tube cools and dissipates the battery through the upper plate, so the battery The cold liquid plate needs to pass through the upper plate to cool and dissipate heat, and the cooling effect between the cold liquid plate and the battery is not good
