ABSTRACT:
A system having a tube-in-tube heat exchanger comprising three coaxial tubular members fitted one within the other with manifolding at each longitudinal end of the exchanger for the circulation of fluid through the outside tubular member in a counterflow direction to fluid passing through the inside tubular member such that heat is exchanged therebetween. A fluid is provided in the intermediate tubular member such that a leak in either the outer or inner tubular members can be detected. Each of the tubular members has integral radially inwardly projecting fins in its bore, the fins of the outer member being in good thermal contact with the intermediate member whose fins, in turn, are in good thermal contact with the inner member such that an effective heat flow path therebetween is provided.
