运用基于CFD的热仿真软件Flotherm对液冷模块进行了热仿真分析,分别研究了在不同环境温度,不同冷却液流量以及不同冷却液温度条件下,液冷模块内部温度场的变化规律。仿真分析结果表明,环境温度对液冷模块的温度场影响非常小;液冷模块冷却液流量的增幅与元器件温度的降幅并非正比关系;元器件温度的升幅与冷却液温度的增幅相同。
The thermal simulation of liquid-cooled module was carried out by using Flotherm, a thermal simulation software based on CFD. The variation of internal temperature field of liquid-cooled module under different ambient temperatures, different coolant flow rates and different coolant temperatures were studied. The simulation results show that the influence of ambient temperature on the temperature field of the liquid-cooled module is very small. The increase of the flow rate of the liquid-cooled module is not directly proportional to the decrease of the temperature of the component. The temperature rise of the component is the same as that of the coolant temperature.
