Abstract: A heat exchanger member (12) having an internal passage in which a baffle assembly (14) is received to define at least two separate flow regions within the passage. The baffle assembly (14) includes a pair of baffles (18, 26), a first (18) of which having a first peripheral portion (22) contacting the wall (16) of the heat exchanger member (12) so as to form a fluid-tight seal therebetween. The first baffle (18) further has a second peripheral portion (24) spaced apart from the wall (16) of the heat exchanger member (12) so as to form a peripheral gap (32) therebetween. The second (26) of the two baffles also has a peripheral portion (30) contacting the wall (12) of the heat exchanger member (12) so as to form a fluid-tight seal therebetween. A second peripheral portion (30) of the second baffle (26) contacts the second peripheral portion (24) of the first baffle (18) so that the baffles (18, 26) are joined together as an assembly.

Abstract: In a heat exchanger (1) including first through M-th tube groups, each tube group comprising at least one exchanger tube (10), and a distribution device (3) which has a distribution tank (30) supplied with a medium and first through M-th distribution paths (31, 32, and 33) for directing the medium from the distribution tank to the first through the M-th tube groups, respectively, medium inlet ports of the first through the M-th distribution paths are coupled to first through M-th regions of the distribution tank that have first through M-th void ratios different to each other. Medium outlet ports of the first through the M-th distribution paths are coupled to the exchanger tubes of the first through the M-th tube groups, respectively.
