The invention belongs to the technical field of power batteries, and provides a cylindrical battery module bracket with a bubble baffle plate for two-phase immersed liquid cooling. The bubble baffle plate is used for guiding the bubble flow generated when the next layer of battery works, so that the uneven temperature between different layers of batteries caused by the influence of the bubble flowgenerated at the lower layer on the heat exchange of the previous layer of battery is avoided. Compared with a traditional cylindrical battery module bracket, the provided cylindrical battery modulebracket has the advantages that the cooling processes of different layers of batteries do not interfere with each other, and the temperature uniformity of different battery monomers is greatly improved; and the bubble baffle plate can play a good role in supporting a middle bearing plate, so that the structure of the middle bearing plate is more stable.
Description
technical field [0001] The invention belongs to the technical field of power batteries, and in particular relates to a cylindrical battery module bracket with air bubble baffles for two-phase submerged liquid cooling. Background technique [0002] Lithium batteries are very sensitive to temperature. At higher temperatures, the impedance of lithium-ion batteries decreases and their performance increases, but high temperatures will also increase the rate of decline of lithium batteries. At lower temperatures, the internal resistance of lithium batteries increases and battery performance decreases. , at extremely low temperatures, it may even lead to lithium precipitation at the negative electrode, seriously affecting the safety of lithium batteries. In order to ensure the good performance and excellent cycle life of lithium batteries, it is necessary to control the working temperature of lithium batteries within a certain temperature range, so the temperature management system...
