ABSTRACT:
A method of making the heat exchanger is also disclosed which includes a ring which is slipped over the periphery of the second tube retaining plate and brazed thereto and a gasket which is slipped over the tube core to form a seal between the first end portion and the elongated housing. An O-ring is slipped over the ring after the replacement of the core tubes within the housing. The O-ring seal forms a seal between the ring and the housing when the two end portions are moved towards each other by adjustable tie rods. An alternative embodiment of the invention includes an annular ledge defined by a ring or seal seat encircling the tube retaining plate and an annular shoulder extending between a bore and a counterbore of the elongated housing. The ledge and the shoulder are coplanar such that an O-ring pressed against a washer seated against the ledge and shoulder seals the annular groove between the tube retaining plate and the housing. A method for converting a flangeless-type heat exchanger into a disassembleable core heat exchanger is disclosed, also.
