Examination of the heat dissipation characteristics in adjustable channel flow for lithium-ion batteries
To address the challenges associated with elevated battery temperatures and uneven temperature distribution dur-ing high-intensity operations,a liquid cooling plate with a closure valve was designed.The efficacy of the innovative cooling plate was benchmarked against the conventional parallel flow path liquid cooling plate through numerical simulation.An investigation was conducted into the effects of variables such as outlet dimensions,outlet positioning,and interceptor length on the cooling effi-ciency and pressure drop characteristics of the novel cooling plate.Findings indicate that the cooling plate with a closure valve a-chieves a reduction in maximum temperature by 4.185%and in maximum temperature increase by 5.431%.Although the inlet and outlet pressure drop experiences a minor increase of 0.723%,this leads to a significant enhancement in overall performance.Moreover,the performance of the cooling plate peaks before diminishing with increasing outlet size and the symmetrical position L.Regarding the impact of the interceptor plate on the cooling plate'sperformance,the following descending order of influence is observed:the fourth group>the second group>the first group>the third group.This is evidenced by variations in maximum temperature,maximum temperature difference,and pressure drop,which change by 2.97 ℃,2.47 ℃,and 134.62 Pa,respec-tively,due to the length of the interceptor plate in the fourth group.
