摘要： An air conditioner and evaporator inlet header distributor therefor are provided. The air conditioner may include an evaporator inlet header distributor to distribute a refrigerant expanded in an expansion mechanism to a plurality of refrigerant flow paths of an evaporator. The evaporator inlet header distributor may include a distributor body, a refrigerant inlet pipe to guide refrigerant expanded in the expansion mechanism to an inside of the distributor body, a plurality of refrigerant outlet pipes to discharge the refrigerant from the distributor body into the plurality of refrigerant flow paths, and a separating plate to separate the inside of the distributor body into a header flow path connected with the plurality of refrigerant outlet pipes and a refrigerant dispersing flow path connected with the refrigerant inlet pipe to guide an upper portion and a lower portion of the header flow path by dispersing the refrigerant. Accordingly, two-phase refrigerant may be uniformly distributed to the plurality of refrigerant outlet pipes using a simple structure.

摘要： 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.
