Abstract
Abstract A thermoelectric cooling device. Thermoelectric modules are interposed between two cylindrical rotors of the type similar to centrifugal fan rotors, with the vanes of the rotors hollowed and filled with a reflux heat transfer fluid. The hollow vanes have fins attached to them. The thermoelectric modules are fed by a direct current source and cause one rotor to get cold and the by, rotor to get hot. The air which is flowing by, and near, each rotor becomes cool or warm, as the case may be. Shrouds around the rotors direct the air flows. The rotors and the thermoelectric modules are rotated, as one unit, by an electric motor.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
133 words
A thermoelectric cooling device, comprising: a. two axially aligned cylindrical rotors having: 1. reservoirs, containing reflux transfer fluid, affixed at each end of each said rotor; 2. a plurality of hollow vanes disposed externally around, and parallel to the common axis of, said rotors, with said vanes attached to said rotors, and joining, and serving as conduits between, said reservoirs of each said rotor; 3. fins attached to, and extending outwardly from, said hollow vanes; b. shrouds, positioned adjacent to and external of said rotors to direct airflow in the desired direction; c. a thermoelectric subassembly, in electrical connection with a source of direct current, interposed between, and connected to, said axially aligned cylindrical rotors; d. and, means for rotating, as one unit, said two axially aligned cylindrical rotors and said thermoelectric subassembly.
