Abstract:
This refrigerant distributor is configured by refrigerant piping and a plurality of heat exchanger tubes being connected, circulates the refrigerant flowing in from the refrigerant piping through channels formed inside, and distributes the refrigerant to the plurality of heat exchanger tubes. This refrigerant distributor comprises a first plate member to which the refrigerant piping is connected, a second plate member, and a third plate member to which the plurality of heat exchanger tubes are connected, the first to third plate members being aligned in the first direction. The first plate member has: an inflow channel that is formed so as to penetrate through the first plate member in the first direction and allows the refrigerant to flow in from the refrigerant piping; and a plurality of turn-back flow channels that allow the refrigerant flowing from the second plate member side to turn back to the second plate member side. The second plate member has a plurality of through channels that are formed so as to penetrate through the second plate member in the first direction. The third plate member has a plurality of protrusions that protrude in the direction opposite from the second plate member. Each of the plurality of through channels communicates with the inflow channel or one of the plurality of turn-back flow channels, and a space that communicates with the plurality of through channels is formed inside each of the plurality of protrusions.
