Document Type and Number:
WIPO Patent Application WO/2018/078746
Kind Code:

Abstract:
Provided are: a distributor for distributing a refrigerant to each of a plurality of vertically extending heat transfer pipes, the distributor having a smaller volume than conventional horizontal distributors; and a heat exchanger provided with the distributor. This distributor (100) distributes a refrigerant to each of a plurality of heat transfer pipes (200) extending in the vertical direction (C) and arranged at a distance from each other in a first direction (A) intersecting the vertical direction. The distributor is provided with: a first member (1) having a plurality of first through-holes (1A) arranged at a distance from each other in the first direction; a second member (2) including a first groove (2A) facing the plurality of first through-holes (1A); and a third member (3) having at least one second groove (3A) disposed facing at least one of the plurality of first through-holes. The first groove extends in the first direction. A first space (S1) within a groove and a second space (S2) within said at least one second groove are connected through third spaces (S3) within the plurality of first through-holes. The flow path resistance of the third spaces is higher than that of the first space and that of the second space.
