(54)	High efficency heat exchanger for a refrigeration system

(57) The heat exchanger includes an elongated housing (12) defining a generally cylindrical space through which one of the media is passed. The housing (12) has an inside wall surface (20) thereof which has a given diameter. An elongated heat exchange pipe (26) defining a tortuous path for the other of the media is adapted to be disposed within the housing (12). The heat exchanger pipe (26) has an effective outer diameter (27)which is less than that of the given diameter of the housing (12). A spacer (34) is provided for engaging the inside wall surface (20) and the heat exchange pipe (26) for supporting the pipe (26) in a predetermined spaced relationship with the inside wall surface.
