| 摘 要： | 采用势函数叠加理论推导了4根冻结管以任意形式排列冻结时的稳态温度场解析解，得出了4根冻结管以等间距直线、矩形和菱形等排列时的稳态温度场特定解，并用热学数值模拟方法对解析解进行验证.结果表明，解析解的计算结果与数值模拟结果较吻合.

| Abstract: | Based on the potential superposition theory, this paper gives analytical solutions to steady state frozen temperature of four freezing pipes arranged at random. Particular solutions are derived for some particular arrangements, such as four freezing pipes with rectangle arrangement and rhombus arrangement. Comparison of the analytical solutions with the numerical thermal analysis shows that the analytical solutions are precise enough. |
