摘要：

This paper studies the heat and mass transfer characteristics of corrugated plate spray humidification air coolers as a new air cooling technology under wet working conditions. In terms of the air cooling effect, the spray cooling characteristics comparisons of the same nozzle under different layouts are made. The TF6 nozzle spray with a layout of 500 mmx500 mm is adopted as the optimal working condition for the heat and mass transfer characteristics. The experimental data under wet working conditions are fit on the basis of the corrugated plate heat exchanger resistance and heat transfer characteristics under dry working conditions. The results show that the spray increases the LMTD of the corrugated plate heat exchanger and significantly increases the air side heat transfer coefficient without jamming the air side runner or increasing the air resistance.
