Abstract: A parallel-flow-type heat exchanger (1) includes a core (11) having flat, multi-hole pipes (2) arrayed in parallel with fins (3) interposed therebetween, the flat, multi-hole pipes and the fins being alternately stacked in an up-down direction. A first header (4) is disposed at one end of the core in a longitudinal direction of the flat, multi-hole pipes and a second header is disposed at the other end of the core in the longitudinal direction. The plurality of flat, multi-hole pipes is divided into at least a first group (21) having a first number of the flat, multi-hole pipes, which group is located most upward of the core, and a second group (22) having a second number of the flat, multi-hole pipes, which group is downward of and adjacent to the first group. The first number is 14 or more, and the second number is less than the first number.

Abstract: An aluminum alloy brazing sheet used for brazing in an inert gas atmosphere without using a flux includes a brazing material cladded onto at least one side surface of a core material. An oxide is formed on a surface of the aluminum alloy brazing sheet by brazing heating, the oxide including any one or two or more of Mg, Li, and Ca and having a volume change ratio of 0.990 or less to a surface oxide film formed before brazing heating, and an atomic molar ratio of Mg, Li, and Ca to Al in the oxide formed on the surface of the aluminum alloy brazing sheet before brazing heating is 0.50 or less. The present invention provides an aluminum alloy brazing sheet having excellent brazability in brazing in an inert gas atmosphere without using a flux, and a method for manufacturing the same.
