Abstract:
A method making a heat exchanger member comprising the steps of:providing a first baffle member having a first peripheral portion and a second peripheral portion;providing a second baffle member having a first peripheral portion and a second peripheral portion;installing the first and second baffle members in an internal passage of a heat exchanger member so as to define at least two separate flow regions within the internal passage, the first peripheral walls of the first and second baffle members contacting a wall of the heat exchanger member so as to form fluid-tight seals therebetween, the second peripheral portion of the first baffle member being spaced apart from the wall of the heat exchanger member so as to form a peripheral gap therebetween that fluidically communicates with an opening through the wall of the heat exchanger member, the second peripheral portion of the second baffle member contacting the second peripheral portion of the first baffle member so as to form a fluid-tight seal therebetween, the first and second baffle members fluidically sealing the peripheral gap from the two separate flow regions; and thenintroducing fluid under pressure in the two separate flow regions and checking for leaks between the wall and the first and second baffle members by detecting fluid leakage through the opening in the wall.
