Abstract: 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.

Abstract: 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.

Abstract: A heat exchanger includes tubes, a tank, and a prevention plate arranged inside the tank and contacting end surfaces of the tubes to prevent heat medium from flowing into the tubes in a certain region. Flow paths are formed in each tube and arranged in a width direction of the tube. The prevention plate includes a deformable portion elastically deformable by contacting an edge of the opening at a time of inserting the prevention plate into the tank from the opening. The deformable portion of the prevention plate that has been inserted into the tank is restored and receives a reaction force from an inner surface of the tank such that the prevention plate is shifted along the width direction by the reaction force.

Abstract: 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.

Abstract: A heat exchanger includes tubes arranged side by side, and a tank connected to ends of the tubes. The heat exchanger performs heat exchange between a first fluid flowing inside the tubes and a second fluid flowing outside the tubes. The heat exchanger includes a closing member disposed inside the tank and partially closing an opening provided at an end of a predetermined tube that is at least one of the tubes. The predetermined tube has a protrusion formed at the end of the predetermined tube. The closing member has an avoiding structure that avoids interference between the protrusion and the closing member.

Abstract: A heat exchanger is configured to exchange heat between a heat medium and an air. The heat exchanger includes a tube through which the heat medium flows therein, and a fin that is formed by bending a metal plate and that is brazed to a surface of the tube. The fin includes a louver. The surface of the tube defines an introducing groove configured to introduce a brazing material melted at brazing from a connecting portion between the tube and the fin to an other portion.
