Beschreibung
Zusammenfassung:	The present invention provides a heat exchanger having an inner tube forming an inner flow path and having an inlet and an outlet; an outer tube radially surrounding at least a portion of the inner tube and spaced radially outwardly therefrom to form an annular space; and a thermally conductive spiral element wound around the inner tube and disposed in the space, wherein the spiral element forms, in conjunction with the inner tube and the outer tube, a helical flow path through the space, the helical flow path in fluid communication with an inlet and an outlet of the outer tube, and wherein the outer tube is thermally isolated from the spiral element. The invention further provides for collars connecting the outer tube to the inner tube.
