  • Patent number: 7997087
    Abstract: A structure, system and method for controlling a temperature of a heat generating device in a solid medium, wherein heat is extracted from the medium into at least one heat extraction device, the heat extraction device dissipates heat into an environment apart from the medium by a heat sink thermally coupled to the heat extraction device; and heat from the medium is dissipated into the heat sink by a first thermal interface material thermally coupling the heat sink to the medium.
    Type: Grant

  • Patent number: 7838760
    Abstract: A thermoelectric device having at least one unipolar couple element (22) including two legs (22a) of a same electrical conductivity type. A first-temperature stage (24) is connected to one of the two legs. A second-temperature stage (28) is connected across the legs of the at least one unipolar couple element. A third-temperature stage (30) is connected to the other of the two legs. Methods for cooling an object and for thermoelectric power conversion utilize the at least one unipolar couple element to respectively cool an object and produce electrical power.

  • Publication number: 20100257871
    Abstract: A thermoelectric device having at least one thermoelectric unit including at least one thermoelectric pair of n-type and p-type thermoelements, a first header coupled to one side of the thermoelectric pair, and a second header coupled to a second side of the thermoelectric pair. The thermoelectric pair has a thermal conduction channel area smaller than an area of the first header or the second header such that the thermal conduction area is a fraction of the area of the first header or the second header.

  • Publication number: 20090282852
    Abstract: A structure, system and method for controlling a temperature of a heat generating device in a solid medium, wherein heat is extracted from the medium into at least one heat extraction device, the heat extraction device dissipates heat into an environment apart from the medium by a heat sink thermally coupled to the heat extraction device; and heat from the medium is dissipated into the heat sink by a first thermal interface material thermally coupling the heat sink to the medium.

  • Patent number: 7342169
    Abstract: A thermoelectric structure and device including at least first and second material systems having different lattice constants and interposed in contact with each other, and a physical interface at which the at least first and second material systems are joined with a lattice mismatch and at which structural integrity of the first and second material systems is substantially maintained. The at least first and second material systems have a charge carrier transport direction normal to the physical interface and preferably periodically arranged in a superlattice structure.
