In-line heat-exchangers and methods of forming the same |
(57) An in-line heat exchanger (10) comprising first (20) and second lengths (30) of seamless,
walled tubing, the first length of tubing characterized by a larger diameter than
the diameter of the second length of tubing, and the second length of walled tubing
disposed within the first length of walled tubing. A plurality of longitudinally-extending
channels (21) are defined in the wall of at least one of the first and second lengths
of tubing, the channels (21) defining therebetween a plurality of longitudinally-extending
passageways (40) in the area between the walls of the first and second lengths of
tubing. Terminal portions (22a,22b) provided at opposite ends of the first length
of tubing are each sealed with respect to the second length of tubing, each terminal
portion defining one of an inlet or an outlet, and each terminal portion defining
at least one interior passageway between the terminal portion and the wall of the
second length of tubing, the at least one interior passageway (24a;24b) communicating
the plurality of longitudinally-extending passageways (40) with one of the inlet or
outlet.
