摘要

设计了一种新型填料组合板蒸发式冷却器

其将填料与换热板片叠加作为换热元件

通过混合冷却的方式强化传热。搭建了组合板蒸发式冷却器性能测试实验系统

研究了喷淋密度、风量、环境湿球温度及填料层数对组合板蒸发式冷却器传热性能的影响。结果表明:增加风量和喷淋水流量

可以提高蒸发式冷却器的冷却效率

并存在最佳喷淋密度;实验中当空气湿球温度上升9℃

板内工质的出口温度升高2℃

冷却效率提高了3%;相同喷淋密度或空气流速下

热流密度随填料层厚度的增加而增大。

Abstract

A new type filler-plate combination evaporative cooler is designed.The fillers and heat exchanger plates which overlap together are used as heat exchanger components.Thus

the heat transfer is enhanced by mixed strengthened cooling between the fillers and the plates.Moreover

a plate evaporator cooler performance test system was built to study the influence of spray density

air volume

ambient wet bulb temperature and flier layer on plate evaporator cooler's heat transfer property.The results show that:increasing the air volume and spray water flow can improve cooling efficiency of the evaporative cooler

and there is an optimum spray density;during the experiment

when the air wet bulb temperature rises by 9℃

the outlet temperature of working fluid in plates increases by 2℃ and the cooling efficiency is improved by 3%;with the same spray density or air flow

the heat density increases with the filler layer thickness.
