Abstract: An air conditioner including a distributor configured to distribute a fluid to a heat exchanger. The distributor comprises a main pipe; a partition defining a plurality of distribution paths in the main pipe; a first branched pipe inserted into the main pipe as much as first length, linked to a first distribution path of the plurality of distribution paths, connected to a first portion of the heat exchanger; and a second branched pipe inserted into the main pipe as much as second length different from the first length, linked to the first distribution path, connected to a second portion of the heat exchanger. A flow velocity of air exchanging heat at the first portion of the heat exchanger is faster than a flow velocity of air exchanging heat at the second portion of the heat exchanger. The first length is shorter than the second length.

Abstract: A heat exchanger is provided. The heat exchanger comprises: a first header comprising a first globe and a second globe; a second header disposed in parallel with the first header; a tube assembly comprising multiple first tubes for connecting the first header and the second header and causing a refrigerant introduced from the first globe to flow in a first direction toward the position of the second header, and multiple second tubes disposed continuously with the multiple first tubes so as to cause a refrigerant introduced from the second header to flow in a second direction that is opposite to the first direction; and multiple heat exchange-fins individually having multiple insertion portions, into which the multiple first tubes and the multiple second tubes are inserted, respectively, and heat exchange surfaces disposed between the multiple insertion portions. The first heat-exchange fin, which is adjacent to the first header among the multiple heat exchange fins, has a heat-exchange surface including a first surface having a louver formed thereon, and a second surface formed to be flat and adjacent to insertion portions into which multiple second tubes are inserted. The second heat-exchange fin, which is adjacent to the second header, has a heat-exchange surface including a first surface.
