Abstract
The invention discloses an integrated liquid cooling plate, and the integrated liquid cooling plate is fixedly installed on the end face of a lithium battery pack and comprises a liquid cooling integrated plate set and a heating piece; a liquid flow channel is formed in the liquid cooling integrated plate set, the heating piece is attached to the liquid cooling integrated plate set, the liquid flow channel and the heating piece are arranged in a staggered mode, cooling liquid is injected into the liquid flow channel, the circulation loop outside the battery pack circulates the cooling liquid to cool the battery pack, and the heating pieces and the liquid flow channels are arranged in a staggered manner, so the heating pieces directly heat plates of the liquid cooling integrated plate group, heat absorbed by the cooling liquid in the heating process is reduced, the heating efficiency of the heating pieces is improved, and the service life of the battery pack is prolonged. The integrated liquid cooling plate is simple in structure, and the production cost of a temperature control loop outside the battery pack is reduced.
Description
technical field [0001] The invention belongs to the battery field of new energy vehicles, and in particular relates to an integrated liquid cold plate used for battery temperature control. Background technique [0002] In recent years, new energy vehicles have developed rapidly. Lithium-ion power batteries are more and more widely used in the field of new energy vehicles due to their high capacity, long cycle life, and high safety. However, the performance of lithium-ion batteries is greatly affected by temperature, and the battery performance will be greatly affected when the temperature is low or high. Therefore, in the current design of lithium-ion battery packs, the battery will be designed according to the needs of heating and heat dissipation. The heating system and cooling system keep the battery in a suitable temperature range to ensure its performance and service life. [0003] At present, natural cooling and liquid cooling are mainly used for power battery cooling...
