To optimize the overall heat dissipation performance of the straight channel of a cold plate for lithium battery in vehicles, we used the wavy channel to optimize the structure and uses the face-centered central composite design (FCCCD), which takes the overall thermal-hydraulic performance factor as the response to explore the interaction mechanism of the flow field and temperature field in wavy channel of the cold plate. When the amplitude of the wavy channel is 1 mm and the number of cycles is 4, the overall thermal-hydraulic performance will reach its maximum with an increase of 17.4 % relative to the straight channel. Then, for the coolant, we explored the heat transfer performance of the nanofluid. The heat transfer coefficient of the nanofluid with a volume fraction of 2 % is 117 % higher than that of pure water and does not cause a significant increase in pressure drop.

为了优化车辆锂电池冷板直通道的整体散热性能，我们使用了波浪通道来优化结构，并使用了以面心为中心的中央复合设计（FCCCD），该设计采用了整体热工液压系统。以性能因子为响应，探索冷板波浪通道内流场与温度场的相互作用机理。当波状通道的振幅为1 mm且循环数为4时，相对于直通道，整体热工液压性能将达到最高，增加17.4％。然后，对于冷却剂，我们探索了纳米流体的传热性能。
