摘　　要：为了获得准确的温升模型,开展了在铜排不同端面对流换热系数提取试验。首先,依据传热学相关理论,通过铜排温升试验获得了铜排不同端面的热功率、热传导热量,并运用牛顿冷却公式求解了铜排不同端面的对流换热系数;然后,利用ANSYS有限元软件建立了铜排温升模型,并将计算求解的对流换热系数代入ANSYS仿真模型中,进行了稳态温升计算;最后,将仿真与试验所得的温度分布进行了对比,结果验证了ANSYS仿真模型的准确性和可行性。To get an accurate temperature rise model,an experiment is carried out for the extraction of convective heat transfer coefficient of different end surfaces.Firstly,in accordance with heat transfer theory,the thermal power and the total amount of thermal conduction is calculated by adopting the heating experiment on the copper platoon.And then,the Newtonian Cooling Formula is applied to get the convective heat transfer coefficient on different faces of the copper.Secondly,a copper platoon heat-rising model is built using ANSYS,and then the convective heat transfer coefficient is put into this model to conduct a stable heat-rising calculation.Finally,comparison of the temperature distribution obtained from the simulation and the experiment verifies the accuracy and feasibility of ANSYS simulation model.
