两种不同水管冷却热传导计算模型相关性探讨

对两种不同水管冷却热传导计算模型的相关性进行了探讨。通过对不同冷却时间以及不同绝热温升速率下两种不同水管冷却热传导计算模型计算的温度历程线进行对比分析，得到结论：①随着结点与水管距离的增加，水管冷却有限元法计算的结点温度与水管冷却等效热传导法计算的结点温度的关系为：先前者小于后者，然后前者大于后者，在距离水管为 0.6 m左右两者温度接近相等；②随着绝热温升放热速率减小，水管冷却等效热传导法和水管冷却有限元法计算的温度值趋于一致所需要的时间越长，但停止通水7d后，两种不同的冷却水管计算模型计算的温度值趋于接近。

Correlation of Conduction Calculation Model for Two Different Cooling Pipes Heat

The temperature graphs calculated by two different cooling pipe heat conduction calculation models are compared with different cooling times and different thermal adiabatic temperature rise rates.Some conclusions are obtained as follows:(1) As the distance between the node and the pipe increases,the relation of node temperature calculated by cooling pipe FEM model and cooling pipe equivalent model shows that former is smaller than the latter,then after,the former bigger than the latter,and the former is equ...
