Kind Code:
A1
Abstract:
A parallel-flow heat exchanger (1) is provided with: a core (11) in which a plurality of flat multi-hole tubes (2) are arranged in parallel with fins (3) therebetween, and the flat multi-hole tubes (2) and the fins (3) are alternately stacked in the vertical direction; a first header (4) disposed at one end of the core (11) in the longitudinal direction of the flat multi-hole tubes (2); and a second header (5) disposed at the other end of the core (11) in the longitudinal direction. The plurality of flat multi-hole tubes (2) are divided into a plurality of flat multi-hole tube groups including a first flat multi-hole tube group (21) located at the uppermost position in the core (11) and a second flat multi-hole tube group (22) downwardly adjacent to the first flat multi-hole tube group (21). The number of flat multi-hole tubes (2) belonging to the second flat multi-hole tube group (22) is 14 or more, and the number of flat multi-hole tubes (2) belonging to the first flat multi-hole tube group (21) is equal to or less than the number of flat multi-hole tubes (2) belonging to the second flat multi-hole tube group (22).
