The invention discloses a heat conduction plate for a high-power power storage battery cell of a rail transit vehicle. A heat source is arranged above the heat conduction plate, a cold source is arranged below the heat conduction plate, and the heat conduction plate is characterized in that a plurality of alternately arranged working medium flowing channels are arranged in the heat conduction plate, liquid absorption cores are arranged in the working medium flowing channels, and the length of the working medium flowing channels is smaller than the rising height of the capillary force of the liquid absorption cores. According to the heat conduction plate for the battery cell of the storage battery, the adjacent working medium flowing channels are alternately arranged, so that cold and heat transfer is carried out between an upper heat source and a lower cold source, and heat transfer is carried out between liquid at a condensation end and a heat source end through capillary acting force of the liquid absorption cores, so that the problem of non-uniform temperature of the battery cell is solved, the heat conduction plate has good thermal conductivity, the whole battery cell can keep good temperature uniformity, the heat exchange efficiency of the battery cell of the storage battery is improved, and the application range is wide.
Description
technical field [0001] The invention relates to the technical field of phase conversion heat, in particular to a heat conduction plate for a high-power power storage battery of a rail transit vehicle. Background technique [0002] In recent years, with the increasingly prominent energy crisis and environmental problems, countries around the world are actively formulating energy development strategies and developing new and renewable energy sources. Among them, as a new type of energy, power batteries have been widely used in electric vehicles, hybrid locomotives, EMUs and grid energy storage. At present, power lithium batteries in the field of rail transportation are developing towards high energy density, large capacity, high power, and high safety and reliability, which puts forward higher requirements for the thermal management of power lithium batteries. [0003] The thermal management of power lithium batteries has always been one of the key research contents in the fi...
