提出了一种新的梯形剖面肋片管沿肋高 (即沿肋根至肋端方向 )温度分布计算方法 ,实测结果表明这一计算方法有较高精度 ,实验同时显示了沿肋宽方向 (即沿肋片的厚度方向 )的温度分布不均匀性 ,对环肋结构优化有重要参考作用 A new method for calculating the temperature distribution along the rib height (ie, along the rib root to the rib end) of the trapezoidal profile finned tube was proposed. The experimental results show that this method has higher accuracy and the experimental results show that the temperature distribution along the rib width direction That is, along the thickness of the fins) inhomogeneity of temperature distribution, an important reference for the optimization of the ring rib structure
