ABSTRACT:
A heat-transfer device has a sealed vapor chamber with a phase-change fluid therein, and a thermoelectric cooling (TEC) element with a cooled side in thermal contact with the vapor chamber and a heated side in contact with heat-dissipation fins. The TEC element decreases the temperature of the vapor chamber and increases the temperature of the fins for improved efficiency. The vapor chamber is defined between concentrically positioned tubes, and a tunnel region is located within the inner tube. Additional TEC elements within the tunnel region further dissipate heat. In two-phase natural convection embodiments, TEC elements may further cool liquid returning to the heat source. Parallel heat dissipation paths may also be provided. In a two-phase forced convection embodiment, a TEC element may further cool liquid returning to the heat source, and additional TEC elements may be provided on the condenser. In some embodiments, active feedback controls the amount of energy transferred by a TEC element.
