Résumé

The cooling effect with application of evaporative cooling was found to be improved considerably compared with that in the sensible cooler. This is because the thermal conductance between the fin and the air increases due to the latent heat transfer caused by the water evaporation from the fin surface. Fin thickness is also very important. The fin thickness in the evaporative cooler should be increased to a greater extent than that in the sensible cooler to take full advantage of the cooling enhancement by water evaporation.
