Abstract: A condenser for a refrigerator according the present invention includes a heat exchange unit configured to receive at one side thereof refrigerant, which has been compressed in a compressor, to perform heat exchange between the refrigerant and air and to discharge the refrigerant, which has exchanged heat with the air, to an evaporator, wherein the heat exchange unit includes a flat tube, through one end of which the refrigerant is introduced and through a remaining end of which the refrigerant is discharged, thereby performing heat exchange between the refrigerant and the air, wherein the flat tube includes at least one bent tube portion defining plural rows of tubes, which are spaced apart from each other in an up-and-down direction, and wherein the plural rows of tubes define an intersection bent surface, which has a predetermined curvature and intersects the up-and-down direction.

Abstract: Provided is an outdoor unit of an air conditioner, including: an outdoor heat exchanger that has a height longer than a width; and an outdoor blowing fan that is disposed above the outdoor heat exchanger and blows air upward from below the outdoor heat exchanger, in which the outdoor heat exchanger includes: a plurality of radiating fins that contacts air; a gap that is formed between the radiating fins; a louver fin that is cut in the radiating fin and then bent; and a cut-out area that is formed in the radiating fin and formed at a position where the louver fin is cut, the radiating fin includes: a first zone that is disposed above the outdoor heat exchanger and disposed close to the outdoor blowing fan; and a second zone that is located below the first zone, and an area LA1 of the louver fin in the first zone is formed to be larger than an area LA2 of the louver fin in the second zone.
The present disclosure has the advantage of uniformly forming air volumes in each zone of the heat exchanger in the vertical height direction by making the areas of the louver fins arranged in each zone different, even when the outdoor blowing fan is disposed to be biased upward.

Abstract: Provided is a heat exchanger. The heat exchanger includes a refrigerant tube through which a refrigerant flows and a fin having at least two tube through holes in which the refrigerant tube is inserted. The fin includes a fin body, a plurality of flow guide protruding from one surface of the fin body, the plurality of flow guides being spaced apart from each other, and a plane part partitioning one flow guide and the other flow guide of the plurality of flow guides, the plane part having a flat surface.
