摘要

从吸水性材料、换热器结构及布水方式入手，设计了采用功能性纤维套、铝箔椭圆管和间歇性供水方式等强化换热措施的间接蒸发冷却器结构。功能性纤维套采用异形涤纶和Lanseal纤维混纺而成，大大加强了水膜导热和水膜表面的蒸发能力；间歇性供水方式保证了管外纤维套凹坑及纤维凹槽不会被水膜堵塞，提供了足够的换热面积；使用铝箔椭圆管并对排列的几何参数进行优化设计，使间接蒸发冷却器的换热性能达到最优化。实验结果表明这种新型管式间接蒸发冷却器和板式间接蒸发冷却器有相近的换热效率E，但阻力明显小于板式。

Abstract

Starting from absorbing water materials

configuration of heat exchanger and supplying water ways

designs the configuration of the indirect evaporative cooler(IEC) adopted the measures of intensify translating heat of functional knitting

ellipse type aluminum foil tube

intermittent water supply.Functional knitting is made of abnormity terylene and 'Lanseal' fiber

this intensifies heat-transfer capacity of water film and evaporative cooling of water film surface;Intermittent water supply guarantees that the notches of knitting surface and the fiber grooves cannot be jammed so that it provides more evaporative cooling surface areas;Employs ellipse type aluminum foil tube and optimizes geometrical parameters of space between rows and platoons

in order to get the best characters of heat exchange of IEC.The results of experiments indicate that new tube type IEC can provide near heat exchange efficiency as plan type IEC

but the resistance of tube type IEC less than plan type IEC.
