摘要： In a heat exchanger, each of a plurality of heat exchange members includes: a main body portion including a heat transfer pipe; and extending portions provided to the main body. The extending portions extend from ends of the main body portion in a third direction. When a dimension of the main body portion in the third direction is represented by La, a dimension of the extending portions in the third direction is represented by Lf, a dimension of a wall thickness of each of the heat transfer pipes is represented by tp, and a thickness dimension of each of the extending portions is represented by Tf, relationships: Lf/La≥1 and Tf≤tp are satisfied.

摘要： 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.

摘要： Provided is a heat exchanger, including: a refrigerant distributor including: a gas-liquid separating portion having a function of separating a gas-liquid refrigerant mixture into a liquid refrigerant and a gas refrigerant; and a distributing portion provided to the gas-liquid separating portion. A plurality of heat transfer pipes connected to the distributing portion. The plurality of heat transfer pipes are arranged side by side in a first direction, and extend along a second direction intersecting with the first direction. When the refrigerant distributor is viewed along a direction orthogonal to each of the first direction and the second direction, a first space forming portion overlaps a region of the plurality of heat transfer pipes. When the refrigerant distributor and the heat transfer pipes are viewed along the first direction, a clearance is present between the gas-liquid separating portion and the heat transfer pipes.

摘要： In a heat exchanger, each of a plurality of heat exchange members includes: a flat pipe; and a heat transfer plate integrated with the flat pipe along a longitudinal direction of the flat pipe. A width direction of each of the flat pipes intersects with a direction in which the plurality of heat exchange members are arranged side by side. Each of the heat transfer plates includes an extending portion extending outward in the width direction of each of the flat pipes from at least one of one end of a corresponding one of the flat pipes in the width direction and another end of the corresponding one of the flat pipes in the width direction. Each of the flat pipes has one or more flat pipe bent portions, each forming a groove extending along the longitudinal direction of the flat pipes.

摘要： A distributor includes a first branch flow path for dividing a first flow path into a plurality of second flow paths, and includes a first communication flow path communicating with the first flow path, a second communication flow path communicating with each of the second flow paths, and a bent portion connecting the first and second communication flow paths. The bent portion includes an inner peripheral wall portion including an inner face having a first radius of curvature, and an outer peripheral wall portion including an inner face having a second radius of curvature larger than the first radius of curvature. The second communication flow path includes an inner wall portion extending from the inner peripheral wall portion of the bent portion, an outer wall portion extending from the outer peripheral wall portion of the bent portion, a base portion and a tip portion. The distance between oppositely facing side walls of the base portion is greater than the distance between oppositely facing side walls of the tip portion. The outer wall portion has a liquid film separation unit that forms a boundary between the base portion and the top portion.

摘要： A heat exchanger, in which refrigerant causing disproportionation is used, includes a main heat exchange unit including a plurality of first heat transfer pipes arranged side by side, a sub-heat exchange unit including a plurality of second heat transfer pipes arranged side by side, and a relay unit including a plurality of relay passages connecting the plurality of first heat transfer pipes and the plurality of second heat transfer pipes. Each of the plurality of relay passages has one inlet connected to a corresponding one of the plurality of second heat transfer pipes, and a plurality of outlets each connected to a corresponding one of the plurality of first heat transfer pipes. Each of the plurality of relay passages distributes the refrigerant flowing from the one inlet, without merging streams of the refrigerant together, and causes the refrigerant to flow out of the plurality of outlets.
