Abstract
A heat exchanger is provided capable of suppressing formation of frost, thereby achieving enhanced heat exchange efficiency refrigerator. The heat exchanger includes refrigerant tubes vertically spaced apart from one another, and heat exchanging fins spaced apart from another in a longitudinal direction of the refrigerant tubes while being coupled to surfaces of the refrigerant tubes. Each heat exchanging fin includes fitting slots formed at one lateral end of the heat exchanging fin and vertically arranged to receive a plurality of refrigerant tubes, and moisture guide valleys extending vertically to downwardly guide moisture on the heat exchanging fin. Each moisture guide valley includes a first moisture guide valley arranged along a virtual line extending through a boundary between a curved portion of the corresponding fitting slot and each straight portion of the fitting slot, and a second moisture guide valley to guide moisture to the first moisture guide valley.
