摘要

蛇形扁平管在空冷机组的应用上取得了较好的效果

为进一步提高机组空冷凝汽器的冷凝效率

优化翅片式扁平管的结构

建立了间断波纹翅片式扁平管通道的三维物理数学模型。通过对对流换热系数、气侧换热量、流动损失的对比分析表明

间断波纹翅片式扁平管在空气侧换热量和流动损失方面比蛇形翅片式扁平管有一定的优势。

Abstract

Better effectiveness had been obtained in applying snake-shaped finned flat tubes onto air-cooled units.In order to further enhance the condensing efficiency of air-cooled condensers for the said units

and optimize the structure of finned flat tubes

a three-dimenssional physico-mathematical model of a channel formulated by discontinuously corrugated fin flat tubes has been established.Through comparison and analysis of the convection heat transfer coefficient

heat amount transferred to the air side

and the flow loss etc.

it shows that the discontinuously corrogated fin flat tubes boast certain superiority in aspects of the heat amount transferred to air side and the flow loss as compared with that of the snake-shaped finned flat tubes.
