本文以锂电池加热烘箱为研究对象，使用SolidWorks对锂电池加热烘箱进行了三维建模和简化处理，在Flow Simulation模块中基于$k？\epsilon$ 湍流方程完成了对烘箱进行了流体仿真，重点探讨了烘箱内部气流与温度分布对磷酸铁锂电池板加热效果的影响。在实验中，设定进风口温度为60℃，对磷酸铁锂电池板进行了20分钟的加热，其中0~800秒的风量为12 m³/s，800~1200秒的风量为8 m³/s。通过流体仿真，获得了锂电池板表面的温度分布图，以及烘箱内部的流线温度图、速度图和压力图。结果表明，在上述条件下，烘箱内锂电池经过20分钟加热后，最低温度为37.17℃，最高温度为52.33℃，满足产品设计要求，证明此烘箱结构设计合理，且这一研究为进一步优化锂电池加热烘箱的结构设计提供了重要的实验依据。
Taking the lithium battery heating oven as the research object, this paper uses SolidWorks to conduct three-dimensional modeling and simplified processing of the lithium battery heating oven, and completes fluid Simulation of the oven based on turbulence equation in the Flow Simulation module. The influence of air flow and temperature distribution in oven on the heating effect of lithium iron phosphate panel is discussed. In the experiment, the inlet temperature was set to 60？C, and the lithium iron phosphate panel was heated for 20 minutes, in which the air volume was 12 m³/s for 0~800 seconds and 8 m³/s for 800~1200 seconds. Through fluid simulation, the temperature distribution diagram of the surface of the lithium panel, and the flow line temperature diagram, velocity diagram and pressure diagram inside the oven are obtained. The results show that under the above conditions, after heating the lithium battery in the oven for 20 minutes, the lowest temperature is 37.17？C, and the highest temperature is 52.33？C, which meets the requirements of product design, proving that the structural design of the oven is reasonable, and this study provides an important experimental basis for further optimizing the structural design of the lithium battery heating oven.
