Effects of Splitter Plate on Heat Dissipation of Lithium-ion Battery Packs for Electric Vehicles
The heat dissipation of lithium-ion battery packs for electric vehicles has an important impact on the safety performance of automobiles.The cylindrical battery combined splitter plate can increase the heat exchange in the heat ex-change channel.In order to optimize the heat transfer performance of the battery pack with the combined splitter plate,this paper numerically analyzed the length of the splitter plate performance on heat transfer characteristics in the heat ex-change channel of the cylindrical battery using FLUENT software by changing the ratio of plate length to splitter plate from 0.5 to 1.5.The results show that the plate-length ratio of the splitter plate has a great influence on the heat transfer for the heat exchange channel of the cylindrical battery.As the ratio of plate length increases,the average Nu also gradu-ally increases.When the ratio of plate length is 1.5,the average Nu are the largest,the heat transfer performance is opti-mal.Compared with the optical channel,the average Nu increases by 64.7%.
