Abstract
An offset fin for use in a heat exchanger includes a first corrugation structure and a second corrugation structure. The first corrugation structure includes a plurality of first fins aligned in a first direction. The second corrugation structure includes a plurality of second fins aligned in the first direction. The second corrugation structure is disposed in a second direction orthogonal to the first direction, with respect to the first corrugation structure. The first fins and the second fins protrude alternately in a third direction orthogonal to both the first direction and the second direction, and each have a protruding shape cross-section. In the first direction, the second fins are disposed offset from the first fins. Each of the first fins includes a first side wall inclined with respect to the second direction, and each of the second fins includes a second side wall inclined with respect to the second direction, at a side opposite to a side at which the first side wall is inclined.
