1. A thermoelectric power generator comprising:
- a plurality of thermoelectric elements forming at least one thermoelectric array with at least one first side and at least one second side exhibiting a temperature gradient between them during operation, at least a portion of the at least one thermoelectric array is configured to permit generally steady-state convective heat transport toward at least one side of at least a portion of the thermoelectric array, wherein at least one convective medium flows at least one of inside, outside and through at least a portion of the thermoelectric array, receives heat from the thermoelectric elements, and convects thermal power through the array, further wherein the thermoelectric power generator is fluidly connectable to either at least one co-generator or heating or cooling system configured to use the thermal power.

Abstract
An improved efficiency thermoelectric system is disclosed wherein convection is actively facilitated through a thermoelectric array. Thermoelectrics are commonly used for cooling and heating applications. Thermal power is convected through a thermoelectric array toward at least one side of the thermoelectric array, which leads to increased efficiency. Several different configurations are disclosed to provide convective thermal power transport, using a convective medium. In addition, a control system is disclosed which responds to one or more inputs to make adjustments to the thermoelectric system.

16. A method of improving efficiency in a thermoelectric power generator having a plurality of thermoelectric elements forming at least one thermoelectric array having at least one first side and at least one second side exhibiting at least one temperature gradient between them during operation of the thermoelectric power generator through the introduction of heat to the system, the method comprising:
-
actively convecting thermal power through at least a portion of the array in a generally steady-state manner with at least one convective medium, wherein the at least one convective medium flows at least one of inside, outside and through at least a portion of the thermoelectric array and receives heat from the thermoelectric elements, further wherein the power generator is fluidly connectable to either at least one co-generator or heating or cooling system configured to use the thermal power; and generating power from the at least one thermoelectric array. - View Dependent Claims (17, 18, 19, 20)
