PROBLEM TO BE SOLVED: To provide a cool air fan showing a superior vaporization efficiency and capable of positively getting cooling effect.SOLUTION: This invention relates to a cool air fan in which a vaporization filter 2 is provided near a rear surface 10B of a casing 10. The vaporization filter 2 is constituted in such a way that a first corrugated band made of pine pulp and solidification agent with corrugated irregularity being formed in a forward downward inclination state and having entire vertical fine band-like shape and a second corrugated band with corrugated irregularity being formed in a rearward downward inclination state and having entire vertical fine band-like shape are alternatively laminated in a lateral direction, many small holes 13 are formed by the first corrugated band and the second corrugated band. Water is supplied from above the vaporization filter 2, air is passed through the small holes 13 while water is being flowed down and cooling is carried out by vaporization heat.SELECTED DRAWING: Figure 1 |
