  • Publication number: 20110315181
    Abstract: A method for converting heat to electricity by exploiting changes in spontaneous polarization that occur in electrically polarizable materials is described. The method uses an internally generated field to achieve poling during cycling. The internal poling field is produced by retaining residual free charges on the electrodes at the appropriate point of each cycle. The method obviates the need for applying a DC voltage during cycling and permits the use of the electrical energy that occurs during poling rather than an external poling voltage which detracts from the net energy produced per cycle. The method is not limited to a specific thermodynamic cycle and can be used with any thermodynamic cycle for converting heat to electricity by thermally cycling electrically polarizable materials. The electrical energy generated can be used in various applications or stored for later use. An apparatus for converting heat to electricity is also described.

    Abstract: The thermoelectric structure is formed by a network of wires oriented substantially in a weft direction of the structure. It comprises first and second conducting wires of different kinds, interwoven to form cold and hot junctions distributed respectively in a top plane and a bottom plane. The junctions are alternately cold and hot along any one conducting wire. The thermoelectric structure comprises at least one high dielectric wire in the top plane, and at least one low dielectric wire in the bottom plane. The dielectric wires are interwoven with the first and second conducting wires so as to keep the top and bottom planes at a distance from one another.

  • Patent number: 7166796
    Abstract: In devices used for the direct conversion of heat into electricity, or vice versa, known in the art as thermoelectric power generators, thermoelectric refrigerators and thermoelectric heat pumps, the efficiency of energy conversion and/or coefficient of performance have been considerably lower than those of conventional reciprocating or rotary, heat engines and/or vapor-compression systems, employing certain refrigerants. The energy conversion efficiency of power generating devices, for example, aside from the hot and cold junction temperatures, also depends on a parameter known in the art as the thermoelectric figure of merit Z=S2?/k, where S is the thermoelectric power, ? is the electrical conductivity and k is the thermal conductivity, of the material that constitutes the p-type, and/or n-type, thermoelements, or branches, of the said devices. In order to achieve a considerable increase in the energy conversion efficiency, a thermoelectric figure of merit of the order of 10?2 K?1, or more, is needed.

  • Publication number: 20040226600
    Abstract: An improved gas pilot control apparatus with an improved thermopile construction comprised of a consolidated thermocouple and thermopile capable of providing multiple EMF signals to operate a gas valve, transmitter/receiver and other components when positioned relative to a pilot flame. The improved thermopile requires a pilot flame of typically 500 BTU/hr to generate the EMF milli voltage required by modern gas valves to maintain reliable, rapid and safe operation of the appliance. The improved thermopile is electrically connected to an electromagnetic valve that controls the flow of gas from the source of supply to the pilot and main burner. The thermopiles are electrically connected to electromagnetic valves and to a transmitter/receiver that remotely control the flow of gas to the main burner.

  • Patent number: 6756536
    Abstract: A thermoelectric microactuator on a substrate includes a first temperature control element having a first surface bonded to the substrate and having a second surface. A first electrically nonconductive layer has a first surface bonded to the second surface of the first temperature control element and has a second surface. An actuator arm includes a first region bonded to the second surface of the first nonconductive layer and includes a flexure contiguously extending from the first region to an end cantilevered beyond the first nonconductive layer and forming an axis at the junction of the flexure and the first region. The first temperature control element controls the temperature of the actuator arm to thereby deflect the flexure about the axis.

  • Patent number: 6717225
    Abstract: A Seebeck effect thermal sensor is formed in an integrated fashion with a power-dissipating device such as a power MOSFET. The integrated device generates a temperature difference between a relatively cold peripheral area and a relatively warm central area, the temperature difference having a known relationship to electrical operating conditions of the device. A structure for a power MOSFET includes two side-by-side arrays of source/drain diffusions. The Seebeck sensor has warm junctions at the central area and cold junctions at the peripheral area, and generates an electrical output signal having a known relationship to the temperature difference between the peripheral and central areas to provide an indication of the electrical operating conditions of the device. One Seebeck sensor includes alternating metal and polysilicon traces, wherein the polysilicon traces lie between source and drain diffusions of a power MOSFET just as do active polysilicon gates.

  • Patent number: 6651446
    Abstract: An electrical equipment cabinet is provided that includes an enclosure adapted to contain electrical equipment. A battery compartment, which is located in the enclosure, is adapted to contain at least one battery electrically coupled to the electrical equipment. The battery compartment has first and second opposing side walls, a bottom surface, and a first pair of vents located in the first and second side walls through which external air flows to remove heat. In addition, a second pair of vents, which are also located in the first and second side walls, allow gas emitted by the battery to escape by diffusion. A thermal stabilizing unit is disposed in the battery compartment for regulating the temperature of the battery in contact therewith. The thermal stabilizing unit has a conduit therein for conducting the external air flow between the vents in the first pair of vents.

  • Patent number: 6605773
    Abstract: A thermoelectric generator includes a thermal generator to which thermal energy is provided from a heat source. In order to keep the output voltage of the thermal generator in a range suitable for charging a battery or for directly feeding into the vehicle's electrical system, the rate of heat production of the heat source and/or the cooling power of a cooling device for the thermal generator is controlled by a regulator. For this purpose, the regulator is connected to a temperature sensor which is mounted on the thermal generator. The regulator can be more cost-effectively configured than a D.C. converter between the output side of the thermal generator and the battery so that this converter can be dispensed with.
