根据质量守恒、动量守恒和能量守恒原理，针对微型热管的传热流动问题进行模化分析，建立了它们相应的一维稳态模型，此模型可以用于预测各种不同截面形状的微型热管的内部流动传热问题。与锲型截面微型热管的实验结果比较表明，最大传热能力的理论预测结果与实验结果基本相符；而且还针对梯形截面的微型热管进行了实验研究，与理论预测结果相比表明，理论预测的最大传热能力略高于实验结果，可能原因是工质充装量没有处在最佳值或微型热管边缝上的加工圆角半径确定不准。
According to the principle of conservation of mass, conservation of momentum and conservation of energy, the heat transfer and flow problems of miniature heat pipes are modeled and their corresponding one-dimensional steady-state models are established. The model can be used to predict micro-heat pipes of various cross-sectional shapes Internal heat transfer problem. Compared with the experimental results of the micro-heat pipe with wedge-shaped cross-section, the theoretical predictions of the maximum heat transfer capacity are in good agreement with the experimental results. Moreover, the experimental research on the micro-heat pipe with trapezoidal cross-section is carried out. Compared with the theoretical prediction results, The maximum heat transfer capacity is slightly higher than the experimental results, probably because the working fluid filling capacity is not in the best value or micro-heat pipe edge seam radius is not sure.
