Claim 14:
15. A heat exchanger, comprising:
a motor;
a compressor, comprising:
a stator shaft extending along a longitudinal axis and configured to be held in place by a magnetic linkage with an external stator;
a rotor casing surrounding the stator shaft and configured to be rotated about the longitudinal axis of the stator shaft by the motor, a portion of the rotor casing extending between the stator shaft and the external stator and passing through the longitudinal axis of the stator shaft being allowed to rotate freely relative to the stator shaft and the external stator; and
a plurality of gate rotors supported by gate rotor shafts offset from and perpendicular to the longitudinal axis of the stator shaft, the gate rotor shafts configured to orbit about the longitudinal axis of the stator when the rotor casing is rotated about the longitudinal axis of the stator shaft by the motor;

a first rotary heat exchanger rotationally coupled to the rotor casing and comprising a first plurality of tube sections extending substantially parallel to the longitudinal axis of the stator shaft;
a second rotary heat exchanger rotationally coupled to the first rotary heat exchanger and comprising a second plurality of tube sections extending substantially parallel to the longitudinal axis of the stator shaft, the compressor and the first and second pluralities of tube sections forming part of a sealed fluid circuit extending through the compressor and the first and second rotary heat exchangers.
