摘要： A heat exchanger includes tubes arranged in one direction, and a corrugated fin provided between the tubes. The corrugated fin includes joints joined to the tubes, and fin bodies that connect the joints which are located next to each other along the wave shape. The fin body includes a cut-raised portion that has a shape in which a part of the fin body is cut and raised for promotion of heat transfer. The cut-raised portion includes a cut-raised end on at least one end of the cut-raised portion in the one direction. The cut-raised end has recesses and projections on its surface that increase hydrophilicity of the surface of the cut-raised end.

摘要： A heat exchanger includes a tube, a corrugated fin, and a plurality of grooves. The corrugated fin has a plurality of bent portions and a plurality of fin main bodies disposed between the bent portions. The multiple grooves are arranged at specified intervals from each other and are formed on a surface of the corrugated fin to enhance the hydrophilicity of the surface. The corrugated fin includes a first thick portion in which at least one of the grooves is included and a second thick portion thicker than the first thick portion in a cross-sectional view along an extending direction of the bent portions.

摘要： A cold storage heat exchanger includes: a plurality of refrigerant tubes disposed at intervals, each of the refrigerant tubes including a refrigerant passage that allows a refrigerant to flow therethrough; a cold storage material adjacent to the refrigerant tubes; and a heat transfer suppressor that suppresses heat transfer from the refrigerant tubes to the cold storage material in an overheated area of the refrigerant formed in the refrigerant passage.

摘要： A cold storage heat exchanger includes a plurality of tubes, a coolant flowing in the tubes, a cold storage material container joined to the tubes, the cold storage material container defining a room that houses a cold storage material, and a distribution tank unit that distributes the coolant to the tubes. A coolant passage is formed in the tubes and the distribution tank unit. The distribution tank unit includes an aperture plate that reduces a passage cross-sectional area of the coolant passage. Among the plurality of tubes, the cold storage material container is joined to at least a tube disposed upstream in a coolant flow direction from the aperture plate in the coolant passage. Accordingly, cold storage performance may be improved.
