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 fin for a heat exchanger is joined to an outer surface of a tube, and facilitates a heat exchange between the tube and an air flowing around the tube. A sectional surface of the fin perpendicular to a flowing direction of an air has a corrugated shape that includes multiple flat portions substantially parallel to a flowing direction of the air, and a ridge portion connecting the adjacent flat portions. Multiple louvers cut in and raised from each of the flat portions at a predetermined cut-and-raised angle are disposed on the flat portion along a flowing direction of the air. A thickness of each flat portion is defined as t, a louver pitch of the louvers is defined as PL, and the thickness of each flat portion and the louver pitch satisfy a relationship of 0.035≦t/PL≦0.29.

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 protrusion forming device includes a holding portion holding an object that is be processed, a tool bit having a cutting portion capable of cutting an object held by a holding portion, and a drive portion capable of driving the tool bit. The tool bit is movable along a cut-in pathway so that the cutting portion is inserted into the object. The cutting portion is movable along a further-cut pathway so as to form a protrusion part that is cut in a linear shape and is connected to the object. The tool bit continuously contacts the protrusion part while moving along a forming pathway such that the protrusion part extends perpendicular to an outer surface of the object.
