Abstract
A heat exchanger 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. The refrigerant inlet of the first flow-splitting part communicates with the first passage at a location below the refrigerant inlet of the second flow-splitting part.
