摘要 基于圆管环形翅片的周期性结构特点,建立了圆管环形翅片温的EFG法传热分析模型。通过编程计算,得到了圆管环形翅片的温度、热流量及温度梯度的分布规律。结果表明,EFG法可应用于结构的传热分析,同时,所得结果为圆管的强化传热及散热结构的优化设计奠定了理论基础。 In this paper,a heat transfer model of annular fin of tube based on EFG method was established,according to the periodicity of annular fin of tube. The temperature field and temperature gradient of annular fin of tube was obtained by using the EFG program. The result shows that EFG method can apply to heat transfer problem,and it is provided the fundamental for enhancement of heat transfer of tube and optimization design of heat radiation structure.
