管组连接方式对空冷冷凝器传热影响的研究

An Investigation of the Effect of the Tube Set Connection on the Heat Transfer in the Air-Cooled Condenser

本文通过对空冷冷凝器的试验研究,说明不同管组连接方式对空冷冷凝器的传热有一定的影响。试验表明,对三排空冷冷凝器采用两进一出(即两路并一路)的管组连接方式是一种较好的方式,在相同参数条件下比三路并联的管组连接方式冷凝器的传热系数约提高10%左右。

This paper focuses on the aspect that the tube set connection types are found to have an effect on the heat transfer performance in the air-cooled condensers through a series of type tests. The experimental results show that the three-row air-cooled condenser with '2 way to 1 way' connection type is an ideal type. Under the sam conditions the heat transfer coefficient of the air-cooled condenser with this tube set connection type is 100% higher than that of the air-cooled condenser with the 3 paralle-way tube set connection type.
