Claims

[Scope of Claim for Utility Model Registration] (1) A draining member is provided that collects and guides water such as drain water and defrost water that is retained due to surface tension between the fins at the lower end of the heat exchanger in the direction of gravity. A heat exchanger characterized by: (2) The heat exchanger according to claim 1, wherein the draining member is a fin edge portion formed at an acute angle by extending the lower end of each fin of the heat exchanger downward. (3) The scope of the utility model registration claim, wherein the draining member is a cut-and-raised portion of the bottom plate of a cabinet housing a heat exchanger and brought into contact with the lower end of each fin of the heat exchanger. The heat exchanger according to item 1. (4) The heat exchanger according to claim 3, wherein the cut-and-raised portion is provided with a condensate refrigerant transfer pipe of a refrigerant cycle disposed along the cut-and-raised portion.
