Title:
HEAT EXCHANGER AND PRODUCTION METHOD FOR PLURALITY OF FIN MEMBERS
Document Type and Number:
WIPO Patent Application WO/2011/158329
Kind Code:
A1
Abstract:
Disclosed is a heat exchanger (1) wherein a plurality of fin members (10, 20) with alternate crests (11, 21) and troughs (12, 22) in an orthogonal direction, which is perpendicular to a flow direction in which a coolant flows, are arranged in the flow direction. Each fin member (10, 20) is arranged such that the positions of the peak sections (11b, 21b) of each crest (11, 21) and the positions of the floor sections (12b, 22b) of each trough (12, 22) each overlap in the flow direction. Adjacent crests (11, 21) and troughs (12, 22) in the flow direction are formed such that each has a different width dimension (X1, X2, Y1, Y2) in the orthogonal direction. As a result, heat transfer efficiency can be increased, three fin members (10, 20) that do not require tip section cutting can be easily assembled in a case (40) without play, and the heat exchanger (1) can be configured at low cost.
