A multiplicity of parallel heat transfer tubes (11) each sealed with refrigerant (13) are journaled for rotation at each end and in a bulkhead (4) that separates the air flow channel into ingoing and outgoing parallel channels. Each heat transfer element (1) has closely spaced circular fins (12) extending radially outward from each tube, the spacing between adjacent fins being less than the fin radius. A motor and transmission (2) cause each heat transfer element to rotate about its longitudinal axis (3). |
