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.

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.
