A novel approach for Lithium-ion battery thermal management with streamline shape mini channel cooling plates

The mini-channel cooling plate has been widely used in the Lithium-ion battery thermal management for electric vehicles. The technology development of high efficiency and good temperature uniformity cooling plate can promote the application of electric vehicles by improving the lifespan of the battery. In this study, streamline concept, which is commonly used for the external design of car, aerospace and submarine system to improve the system performance, has been introduced to design and optimise the performance of inner mini channel cooling plate. The flow resistance was proved to be minimised when the streamline shape design was adopted. Moreover, the results have proven the novel designed mini channel cooling plate can keep the heat exchange ability within the acceptable level. The maximum improvement of the heat exchanger efficiency with streamline shape design could be as high as 44.52%. Results indicated the temperature uniformity could also be effectively improved. The streamline shape mini channel cooling plate could be a promising solution for Lithium-ion battery thermal management.
