Heat Exchanger

A heat exchanger, comprising:

• an exterior container which has opposite first and second ends, and defines an internal cavity, and wherein the exterior container is further defined by a longitudinal axis that extends between the opposite first and second ends;
• a refrigerant distribution tube which is positioned within the internal cavity of the exterior container, and is oriented along the longitudinal axis thereof, and wherein the refrigerant distribution tube has a first refrigerant intake end which is located within the internal cavity, and in spaced relation relative to the first end of the exterior container, and a second refrigerant exhaust end, and wherein the second refrigerant exhaust end is located within the internal cavity, and in spaced relation relative to the second end of the exterior container, and wherein the first end of the refrigerant distribution tube is fluid flowingly coupled to a source of a first refrigerant;
• and
• a multiplicity of refrigerant tubes within the internal cavity of the exterior container and each of the multiplicity of refrigerant tubes has a length dimension, and wherein each of the multiplicity of refrigerant tubes are equal in length, and wherein each of the multiplicity of refrigerant tubes further defines a helically shaped coil having a coil length, and wherein each helical coil is equal in length, and wherein the multiplicity of refrigerant tubes are further individually located in a radially outwardly spaced relationship relative to the longitudinal axis of the exterior container, and wherein the respective helical coils defined by each of the multiplicity of refrigerant tubes are either left hand, or right handed in orientation, and are further helically nested together, in both a longitudinal and a radially outward direction, so as to orient the respective multiplicity of refrigerant tubes in a predetermined, closely spaced helical relationship which occupies a majority of a volume of the internal cavity of the exterior container, and wherein the respective multiplicity of refrigerant tubes each have a first intake end, and a second exhaust end, and wherein the first end of each of the multiplicity of refrigerant tubes are further fluid flowing coupled to a second source of a refrigerant, and the second end of each of the multiplicity of the refrigerant tubes is disposed in fluid flowing communication with the second end of the external container.
