一个分析模型被认为是第一个分析微热管模型来预测毛细操作的限制，以及在蒸发器部分的曲率半径和液体充电的最佳值开发的三角形，蚀刻微热管。该模型预测了各种功率水平的最佳液体灌注值在16-25%之间，并且还指示了不超过25%的最佳充注值。使用了具有从10%到50%的液体质数值的微热管阵列。通过比较不同充液比下最大传热量的预测值与实验值，验证了模型的有效性。尽管该模型正确预测了与填充比变化相关的趋势，但预测和测量的干燥水平存在明显差异。参考文献8。
An analytical model considered to be the first analytical micro heat pipe model to predict the capillary limit of operation as well as the radius of curvature in the evaporator section and the optimal value of liquid charge was developed for a triangular-shaped, etched micro heat pipe. This model predicted optimal liquid prime values between 16-25% for various power levels and also indicated an optimal charge value which would not exceed 25%. Micro heat pipe arrays with liquid prime values ranging from 10 to 50% were used. The model was validated by comparing the predicted values of maximum heat transport capacity with experimental data at various liquid fill ratios. Although the model correctly predicted the trends associated with the variations in the fill ratio, significant differences were evident in the predicted and measured dryout level. 8 refs.
