| Abstract: | The structure of flow channels has a significant impact on the thermal management performance of battery liquid cooling plates. In the present study, an imitation Tesla valve liquid cooling plate (TLCP) is proposed. Through the multi-dimensional optimization of flow velocity (0.06-0.12 m/s), the number of channels (3-6 channels), the number of stages (4-12 stages), and the staggered arrangement (4 structures), a synergistic enhancement of heat dissipation performance and system energy efficiency is achieved. The research results demonstrate that the five-channel, 8-stage valve structure attains an optimal balance between heat dissipation efficiency and system pressure. Further optimization through a staggered lay-out: the optimal structure is the five-channel 8-stage TLCP with a d structure under the condition of an inlet velocity of 0.1 m/s, which enables the maximum battery temperature to be controlled at 303.02 K, the maximum temperature difference to be reduced to 3.60 K, and the pressure drop to be only 42.51 Pa. Compared with the honeycomb liquid cooling plate that only differs in flow channel configuration from an equivalent heat dissipation model, this design shows a slight increase of 0.52 K in maximum temperature. However, it achieves a 12.20% reduction in temperature difference and the significant 65.27% reduction in pressure drop. [ABSTRACT FROM AUTHOR] |
