Claims

1. A HEAT EXCHANGER FOR TRANSFERRING HEAT BETWEEN FLUIDS AT DIFFERENT TEMPERATURE COMPRISING:

MEANS DEFINING A FIRST FLUID FLOW PATH, MEANS DEFINING A SECOND FLUID FLOW PATH DISPOSED COAXIALLY OF SAID FIRST PATH AND HEAT TRANSFER ELEMENTS COMMON TO SAID FIRST AND SECOND FLOW PATHS INTERPOSED IN SAID PATHS TO TRANSFER HEAT THEREBETWEEN, SAID MEANS DEFINING A SECOND FLOW PATH INCLUDING A PLURALITY OF DISCRETE LOW HEAT, CONDUCTIVITY SPACER ELEMENTS DISPOSED INTERNALLY OF AND LENGTHWISE OF AT LEAST A PORTION OF SAID FIRST FLUID FLOW PATH AND PERIODICALLY INTERPOSED BETWEEN SAID HEAT-TRANSFER ELEMENTS AND INPUT AND OUTPUT TUBULATION HAVING ENLARGED RESILIENT TRANSITION PORTIONS, AN EXTREMITY OF EACH OF SAID PORTIONS BEING CONNECTED TO A SPACER ELEMENT TO APPLY A COMPRESSIVE FORCE TO SAID SPACER ELEMENTS AND SAID HEAT TRANSFER ELEMENTS TO COMPENSATE FOR DIMENSIONAL CHANGES DUE TO TEMPERATURE VARIATION TO PREVENT FLUID LEAKAGE BETWEEN SAID FIRST AND SECOND FLOW PATHS AND TO CONTROL THE AXIAL MOVEMENT OF SAID SPACER AND HEAT TRANSFER ELEMENTS.
