摘要： A heat exchanger includes tubes through which a first fluid flows, and a corrugated fin configured to improve a heat exchange efficiency between the first fluid flowing through the tubes and a second fluid flowing outside of the tubes. The corrugated fin includes bending portions connected to adjacent two tubes of the tubes and fin body portions extending between the bending portions. Each of the fin body portions includes grooves on a surface thereof and a protrusion. Each of the grooves extends in an extending direction from one of the adjacent two tubes toward the other. The protrusion is disposed at an intermediate position of at least one of the grooves between the adjacent two tubes in the extending direction. The protrusion protrudes from a bottom of the at least one of the grooves toward the surface.

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.
