Provided is a heat exchanger, including a plurality of heat exchange members arranged in a first direction so as to be spaced apart from each other. Each of the plurality of heat exchange members includes: a heat transfer pipe extending in a second direction intersecting with the first direction; and a heat transfer plate provided to the heat transfer pipe along the second direction. The heat transfer plate includes extending portions extending away from the heat transfer pipe in a third direction intersecting with each of the first direction and the second direction. The heat transfer plate is formed separately from the heat transfer pipe.

Heat exchanger and refrigeration cycle apparatus

An auxiliary heat exchange unit of a heat exchanger has a first auxiliary heat exchange region and a second auxiliary heat exchange region. A main heat exchange unit has a first main heat exchange region, a second main heat exchange region, a third main heat exchange region, and a fourth main heat exchange region. The auxiliary heat exchange unit and the main heat exchange unit are configured to cause refrigerant to flow successively through the first auxiliary heat exchange region, the second auxiliary heat exchange region, the first main heat exchange region, the second main heat exchange region, the fourth main heat exchange region, and the third main heat exchange region when the heat exchanger functions as an evaporator.

A heat exchanger to which a fan supplies air includes a plurality of flat tubes extending in a first direction, a corrugated fin connected to the flat tubes and extending in a second direction intersecting the first direction, and a plurality of plate fins connected to at least one of a windward end and a leeward end of the corrugated fin and extending in a third direction intersecting the second direction. This configuration achieves improvement in heat exchange performance.

Heat exchanger, refrigeration cycle device, and air-conditioning apparatus

A distributor includes a first member having a plurality of first through holes spaced apart from each other in the first direction, a second member having a first groove facing each of the plurality of first through holes, and a third member having at least one second groove facing at least one of the plurality of first through holes. The first groove extends in the first direction. The first space inside a groove is connected to a second space inside at least one second groove through a third space inside each of the plurality of first through holes. The third space is higher in flow path resistance than the first space and the second space.
