Abstract: A heat exchanger baffle and method by which the internal passage of a heat exchanger member is divided into two separate flow regions. The baffle includes first and second members having planar portions that define edges of the first and second members. The planar portions are connected to each other so as to form a connection region between the first and second members. The connection region is deformable to enable the planar portions to be folded onto each other. The baffle can then be installed in a heat exchanger member by installing the planar portions together into a slot in the wall of the heat exchanger member. After installation, the planar members remain substantially parallel to each other, and the connection region preferably contacts a portion of the wall opposite the slot. The manner in which the baffle is folded serves to bias the first and second members against the slot, so that the baffle is more reliably retained within the slot prior to being permanently secured by such methods as brazing.

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.
