<p>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.</p> |
