Abstract

The invention provides a water cooling plate structure applied to an electric automobile. The water cooling plate structure comprises a plurality of cooling plates arranged in sequence, wherein gaps for accommodating batteries are reserved among the adjacent cooling plates. Each cooling plate comprises tube bundle plates respectively located at two ends, a plurality of finned flat tubes are sequentially arranged between the tube bundle plates at two ends, water chambers are arranged on the tube bundle plates, and the finned flat tubes are communicated with the water chambers. The water chambers, on the same side, of the adjacent two cooling plates are communicated. At least one of the water chambers on the same side is provided with a module water inlet-outlet. The water cooling plate structure can improve the heat exchange efficiency and the consistency of temperature distribution, is low in cost and easy to process and can be produced in a large-scale mode. The reliability is improved, and the leakage possibility is reduced. The weight is reduced by 60%-80%, the number of weld joints is decreased by 70%-90%, and therefore the problems existing in existing cooling plate design are effectively solved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, gasoline-electric hybrid vehicles or energy storage power supply systems, in particular to a water-cooled plate structure applied to electric vehicles. Background technique [0002] At present, the design of lithium battery packs for electric vehicles pays more and more attention to the design of high energy density and high specific energy. However, while the energy density and specific energy of the battery pack are increasing, the waste heat generated inside the battery pack is also increasing sharply. The increase in waste heat and the increase in temperature in the battery pack pose challenges to the cycle life and operational safety of the battery. For this reason, the current battery pack design requires a relatively advanced and reliable thermal management system. The current main methods of thermal management system design are air cooling and water cooling. Air cooling incre...
