| 摘要 |
The present invention relates to an evaporative cooling heat exchanger comprising: a housing separately having a processing air inflow portion, a processing air supply portion, an upper humidified air inflow portion, and a lower humidified air discharge portion; and a spiral pipe installed in the housing. The present invention is separated into a processing air portion and a humidified air portion by the spiral pipe, and humidified water and humidified air move inside the spiral pipe while processing air moves outside the spiral pipe. Accordingly, the present invention can increase heat exchange cooling efficiency of the evaporative latent heat in maximum since the humidified water is spread out equally in general because of an increase of a heat transfer area and a change of an air moving passage by the spiral pipe. |
