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.-
