Abstract: A method for manufacturing a heat exchanger (1) includes joining an inner fin (3) to a hollow structure (20) formed from at least two clad plates (200a, 200b) by heating and brazing a filler metal layer (B). Each clad plate has a core layer (A) composed of an aluminum alloy that contains Mg: 0.40-1.0 mass %. The filler metal layer is composed of an aluminum alloy that contains Si: 4.0-13.0 mass %, and further contains Li: 0.0040-0.10 mass %, Be: 0.0040-0.10 mass %, and/or Bi: 0.01-0.30 mass %. The inner fin is composed of an aluminum alloy that contains Si: 0.30-0.70 mass % and Mg: 0.35-0.80 mass %. A flux (F) that contains cesium (Cs) is applied along a contact part (201), and the vicinity thereof, of the at least two clad plates prior to the heating. A heat exchanger (1) may be manufactured according to this method.

Abstract: A heat-exchanger heat sink (1; 102; 103; 104) includes a plurality of fin plates (2; 202; 203; 203a, 203b; 205), which are lined up spaced apart from one another in a plate-thickness direction; and at least one linking part (3; 3a, 3b; 304), which is disposed such that it intersects and hold the plurality of fin plates (2). The at least one linking part has a base (31), which may be rod or bar shaped, and a plurality of positioning protrusions (32), which protrude from a side surface of the base. Each of the fin plates has at least one latching groove (21, 26), into which the base is inserted such that each fin plate is located between adjacent positioning protrusions of the at least one linking part.
