Chinese Abstract

針對熱管換熱器設計計算公式複雜,計算工作量大的問題,提出了採用線算圖法進行氣-氣熱管換熱器設計計算的方法。將熱管換熱器設計計算中的對流換熱係數、流動阻力和攜帶傳熱極限計算公式均以線算圖的形式表示,並給出計算實例。線算圖法與常規計算方法相比,兩者的計算結果相差很小,但線算圖法更方便、簡單,同時可以清晰地表示各參數對熱管換熱器性能的影響。

English Abstract

Since the calculating formulas of heat pipe exchanger are complicated and the physical parameters of the working medium at different temperature need to be calculated, a nomographic method for the calculation of gas-gas heat pipe exchanger is presented. By means of this method, the formulas for calculating the convection heat exchange coefficient, the flow resistance and the carrying heat transfer limit are expressed by the pattern of nomography. And the presented method is illustrated by an example. The method is more convenient and simpler than the conventional calculating method, and it can show the influence of each parameter on the performance of the heat pipe exchanger clearly
