摘要： A thermoelectric module comprised of a quantum well thermoelectric material with low thermal conductivity and low electrical resitivity (high conductivity) for producing n-legs and p-legs for thermoelectric modules. These qualities are achieved by fabricating crystalline quantum well super-lattice layers on a substrate material having very low thermal conductivity. Prior to depositing the super-lattice thermoelectric layers the low thermal conductivity substrate is coated with a thin layer of crystalline semi-conductor material, preferably silicon. This greatly improves the thermoelectric quality of the super-lattice quantum well layers. In preferred embodiments the super-lattice layers are about 4 nm to 20 nm thick. In preferred embodiments about 100 to 1000 of these super-lattice layers are deposited on each substrate layer, to provide films of super-lattice layers with thicknesses of in the range of about 0.4 microns to about 20 microns on much thicker substrates. The substrates may be a few microns to a few millimeters thick. The thermoelectric films are then stacked and fabricated into thermoelectric p-legs and n-legs which in turn are fabricated into thermoelectric modules. These layers of quantum well material may in preferred embodiments be separated by much thicker layers of thermal and electrical insulating material such that the volume of insulating material in each leg is at least 20 times larger than the volume of quantum well material.

摘要： Quantum well thermoelectric modules and a low-cost method of mass producing the modules. The devices are comprised of n-legs and p-legs, each leg being comprised of layers of quantum well material in the form of very thin alternating layers. In the n-legs the alternating layers are layers of n-type semiconductor material and electrical insulating material. In the p-legs the alternating layers are layers of p-type semiconductor material and electrical insulating material. Both n-legs and p-legs are comprised of materials providing similar thermal expansion. In preferred embodiments the layers, referred to as super-lattice layers are about 4 nm to 20 nm thick. The layers of quantum well material is separated by much larger layers of thermal and electrical insulating material such that the volume of insulating material in each leg is at least 20 times larger than the volume of quantum well material.

摘要： A self-powered food heater. The food heater includes a burner with an electric fuel pump and an electric blower, a fire box, a water tank and electronic controls. The food heater also includes a set of thermoelectric modules compressed against a heat transfer surface of the tank. Hot exhaust leaving the burner enters the fire box. Some of the heat from the fire box passes through the thermoelectric modules generating sufficient electric power to power the fuel pump and the blower. Water in the tank is heated to its boiling temperature. Heat from the boiling water heats food also contained in the tank. In a preferred embodiment special compression frames provide substantially uniform compression, within desired ranges, of the modules between a portion of the heat transfer surface of the tank and a module cover plate. Fins may be provided on the cover plate or insulating spacers may be added to assure the hot side temperatures of the modules are within desired ranges to provide desired power output without damaging the modules. In a preferred embodiment the modules are compressed against a heat transfer surface on the outside of the tank within the fire box.
