There is disclosed a heat exchanger comprising at least one set of channels having a proximal end and a distal end, the set of channels comprising: a first channel defined by a first skin and a wall; and a second channel defined by a second skin and the wall, wherein the wall located between the first channel and the second channel comprises a first at least one aperture to allow fluid to pass through the wall from the first channel to the second channel.

A heat exchanger according to the present disclosure includes plural heat transfer tubes disposed with a specified spacing from each other in the up and down direction, and a distributor configured to distribute refrigerant to the heat transfer tubes. The distributor includes a body part, and plural flow-splitting parts, the body part including a first passage in which refrigerant flows upward, the flow-splitting parts communicating with the first passage and with one of the heat transfer tubes. The flow-splitting parts include one or more first flow-splitting parts each communicating with a first heat transfer tube, which is a higher positioned heat transfer tube. The flow-splitting parts include one or more second heat transfer tubes each communicating with a second heat transfer tube positioned below the first heat transfer tube.
