ABSTRACT:
A heat exchanger includes a hollow shell that defines an elongate shell space for circulation of a first fluid therethrough, and a plurality of elongate tubes spaced apart inside the shell to conduct a second fluid therethrough in heat exchange relation with the first fluid in the shell space. The heat exchanger further includes an improved assembly for coupling an end of the shell with adjacent ends of the tubes and for conducting the respective fluids separately into and from the tubes and into and from the elongate shell space without leakage. This assembly comprises a socket member having forward and backward socket portions and an annular shoulder portion protruding inwardly between them. The forward portion is connected in fluid-tight relation to an end of the shell and has a passageway extending through it for conducting the first fluid into or from the elongate shell space. The adjacent ends of the tubes extend past the shoulder portion into the backward socket portion and are fixed and sealed respectively in ports formed in a rigid tube support that is displaceable axially in the backward socket portion. A compressible O-ring seal is disposed in the backward socket portion between the shoulder portion and the circumferential area of the tube support outside of the tubes, and a jackscrew assembly is confined in the backward socket portion but is accessible through its backward end to displace the tube support to a position in which it compresses the O-ring seal against the shoulder to thereby isolate the tube ends from the first fluid in the shell space. A suitable piping connects the backward socket portion to a source of a second fluid to be conducted into or from the tube ends.
