摘要

毛细管网换热器由于传热面积大、温度均匀等诸多优点在交通类能源隧道已有较多应用。热力能源隧

道作为一种新型能源隧道因具有内热源而与交通类能源隧道差异较大，为研究毛细管网换热器在热力能源隧道应用的可行性，实验研究了吸热工况下热力能源隧道毛细管网换热器采用1∶1间歇运行模式下的换热性能。结果表明：隧道内初始空气温度越高，毛细管网换热器的换热量越大，在循环水入口温度为5 ℃不变的条件下，隧道内初始空气温度和循环水入口温度温差增加10 ℃，换热量增加45.9%；毛细管网换热器的换热量随着循环水流速的增加而增加，流速增至0.1 m/s后，换热量变化曲线呈水平渐近线变化，换热量逐渐稳定于187.22 W/m

；循环水入口温度越低，换热量越大，当隧道内初始空气温度为50 ℃，循环水流速为0.075 m/s时，循环水入口温度每升高1 ℃，换热量降低2.04%。

Abstract

Capillary mat heat exchangers are increasingly used in transportation energy tunnels owing to their large heat-transfer area and uniform temperature. Thermal energy tunnels

a new type of energy tunnel

differ from transportation energy tunnels because of the heat source inside such tunnels. To examine the feasibility of applying capillary mat heat exchangers in thermal energy tunnels under endothermic conditions

heat transfer performance was experimentally investigated using a 1∶1 intermittent operating mode. The results showed that the higher the initial air temperature (

) in the tunnel

the greater the heat flux. With the inlet temperature of circulating water (

) fixed at 5 ℃

as the temperature difference between

and

increases by 10 ℃

the heat flux increases by 45.9%. The heat flux also increases with the increase of circulating water velocity (

); whereas

increases up to 0.1 m/s

the heat transfer rate saturates and approaches 187.22 W/m

. The lower the

the greater the heat flux. When the

is 50 ℃ and the

is 0.075 m/s

for every 1 ℃ increase in the

the heat transfer rate decreases by 2.04%.
