逆流式波纹隔板露点间接蒸发冷却器性能研究

Studying thepeformance of counter flow corrugated baffle dew-point indirect evaporative

提出一种逆流式波纹隔板露点间接蒸发冷却器,该冷却器可将空气温度降低到湿球温度以下并接近露点温度。本文研究了不同的通道长度、产气通道高度、工作通道高度对露点间接蒸发冷却器冷却效率的影响。结果表明:在研究范围内,湿球效率随通道长度的增加而增大,随产气通道高度的增加而减小。在工作通道高度为2~10mm间时,随工作通道高度的增加,湿球效率先增大后减小,且在工作通道高度为5mm时湿球效率最大。

A counter - flow type dew - point indirect evaporative cooler with corrugated baffle was proposed, which was able to cool air to temperature below ambient wet bulb temperature and approaching wet - point temperature. The effects of the channel length, product channel height and the working channel height on the cooling efficiency dew - point indirect evaporative cooler were investigated. The results show that wet - bulb efficiency increases with the increase of the channel length and decreases with the increase of the channel height. When the working channel height varies from 2 to 10mm, the wet -bulb efficiency increases first and then decreases with the increase of working channel height, and the highest wet - bulb efficiency can be achieved when the working channel height is 5mm.
