A heat exchanger including a heat exchange fin; a refrigerant pipe passing through the heat exchange fin, the refrigerant pipe having a first thickness; a connecting member coupled to the refrigerant pipe; and a distribution pipe coupled to the connecting member at an outside of the heat exchange fin, the distribution pipe having a second thickness greater than the first thickness, wherein the connecting member is positioned between the refrigerant pipe and the distribution pipe so that a refrigerant is flowable through the connecting member between the refrigerant pipe and the distribution pipe, and has a thickness in a range of 95% or more and 105% or less of the second thickness.

Heat exchanger

A heat exchanger for an air conditioner includes a plurality of flat heat transfer tubes through which a refrigerant flows; first and second headers disposed on opposite ends of the plurality of flat heat transfer tubes; at least one baffle disposed in at least one of the first and second headers and to partition an inner space of the at least one header; and a refrigerant flow control device disposed on the at least one baffle, to allow the refrigerant to selectively pass through the at least one baffle. The refrigerant flow control device is configured to prevent refrigerant from passing through the refrigerant flow control device when the refrigerant flows in one direction in the header, and to allow the refrigerant to pass through the refrigerant flow control device when the refrigerant flows in a direction opposite to the one direction in the header.

Heat exchanger and air conditioner including the same

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.
