Abstract: Provided is an indoor unit for an air conditioner. The indoor unit for the air conditioner includes a case having at least one suction hole, a heat exchanger disposed at a side of the suction hole, a fan rotatably disposed at a discharge side of the heat exchanger, a front panel coupled to a front portion of the case, the front panel including a discharge part, a discharge panel disposed on the discharge part, and a guide device disposed to surround the fan, the guide device having a curved surface for guiding air discharged from the fan to the guide part.

Abstract: A heat exchanger of an air conditioner is provided, which may include a first heat exchanger including a plurality of flat tubes that performs heat exchange between a refrigerant and air, an introduction pipe, through which the refrigerant may be introduced, connected to the first heat exchanger, a second heat exchanger including a plurality of flat tubes that performs heat exchange between the refrigerant and the air, the second heat exchanger being provided at an outside of the first heat exchanger, a discharge pipe, through which the refrigerant may be discharged, connected to the second heat exchanger, and a connection pipe connected between the first heat exchanger and the second heat exchanger that supplies the refrigerant discharged from the first heat exchanger to the second heat exchanger. The flat tubes forming the first heat exchanger and the second heat exchanger may be provided to extend in horizontal direction.

Abstract: A heat exchange system is provided that may include a first heat exchanger, a second heat exchanger spaced apart from the first heat exchanger, a connection device provided between the first and second heat exchangers to guide refrigerant into the first and second heat exchangers, and one or more connection pipes that couple the connection device to the first and second heat exchangers, the connection pipes including at least one bent portion.

Abstract: A heat exchanger for an air conditioner and an air conditioner having the same are provided. The heat exchanger may include at least one heat exchange device, the heat exchange device comprising a lower header provided therein with a lower flow path; an upper header provided therein with an upper flow path; and a plurality of flat tubes provided therein with a plurality of flow paths that communicates with the lower flow path and the upper flow path. The upper flow path may be partitioned into a first lower flow path with which a portion of the plurality of flat tubes may communicate, and a second lower flow path with which a remaining portion of the plurality of flat tubes may communicate. Each of an internal sectional area of the upper header and an internal sectional area of the lower header may be 0.7 times or more as large as a sum of sectional areas of flow paths in the plurality of flat tubes forming one path.

Abstract: A heat exchange system and a method of manufacturing the same are provided. The heat exchange system may include a first heat exchanger, a second heat exchanger spaced apart from the first heat exchanger, a connection device provided between the first and second heat exchangers to guide refrigerant into the first and second heat exchangers, and one or more connection pipes that couple the connection device to the first and second heat exchangers, the connection pipes including at least one bent portion.
