Title: Fin for air heat exchanger
Inventor: IGUCHI KAZUYUKI
IPC: F28F1/32
Filed: 1987-07-03
Abstract: PURPOSE:To reduce a defrosting time in defrosting operations and to obtain the comfortable condition of air conditioning by a method wherein a mixed section is formed on a front side face in such a manner that a linear hydrophilic part and a linear hydrophobic part are alternately arranged in an inclined state between adjacent collar parts, a hydrophilic part is formed an the right and left parts of the mixed section, and a hydrophilic part is formed on a rear side face. CONSTITUTION:In a mixed section 5 other than a collar part 2 are formed a linear hydrophilic part 3a and a linear hydrophobic part 4 in an alternate and inclined state, and since the hydrophilic part 3a is formed partly, the drain generated flows down rapidly without staying in a bridge state with an adjacent fin. The drain flows to a right or a left hydrophilic part 3b along the hydrophobic part 4 beneath the hydrophilic part 3a as its flowing path and drops down directly to the lower portion of the fin. Further, since a hydrophilic part 3 is formed on a rear side face where the collar 2 is not swollen out, the drain generated is instantly conformed to the rear side face and drops down. Accordingly, the quantity of the drain is reduced to be able to decrease the number of defrosting times, so that the comfortable condition of air conditioning can be improved to a great extent.
