  • Patent number: 9238398
    Abstract: An exemplary refrigeration system for cooling food or beverages may use a liquid cooling system of a vehicle. The refrigeration system may include a compartment in which the food or beverages may be placed and removed, a chilled liquid coolant system having a connection through which liquid coolant is received from the liquid cooling system of the vehicle, and a heat exchanger operationally coupled with the chilled liquid coolant system and the compartment to transfer heat from the compartment into the liquid coolant. The refrigeration system may also include a second chilled coolant system through which a second coolant flows and a second heat exchanger operationally coupled with the second chilled coolant system and the compartment to transfer heat from the compartment. The chilled liquid coolant system and the second chilled coolant system may operate together as a cascade cooling system.

  • Patent number: 8969703
    Abstract: Inexpensive, lightweight, flexible heating and cooling panels with highly distributed thermoelectric elements are provided. A thermoelectric “string” is described that may be woven or assembled into a variety of insulating panels such as seat cushions, mattresses, pillows, blankets, ceiling tiles, office partitions, under-desk panels, electronic enclosures, building walls, refrigerator walls, and heat conversion panels. The string contains spaced thermoelectric elements which are thermally and electrically connected to lengths of braided, meshed, stranded, foamed, or otherwise expandable and compressible conductor. The elements and a portion of compacted conductor are mounted within the insulating panel On the outsides of the panel, the conductor is expanded to provide a very large surface area of contact with air or other medium for heat absorption on the cold side and for heat dissipation on the hot side.

  • Patent number: 8921683
    Abstract: A solar powered generator (100) has thermoelectric elements adjacent to and below solar cells. Concentrated sunlight is provided. A heat sink (104), which can be variable in temperature or efficiency, is in contact with the cold junction (108) of the thermoelectric device (103). The thermal resistivity is designed in relation to the energy flux, whereby the thermoelectric device (103) develops a gradient of several hundred Kelvin. Preferably the solar cell comprises a high band gap energy semi-conductor. The generator (100) maintains relatively consistent efficiency over a range of cold junction (108) temperatures. The heat sink (104) can be a hot water system. High efficiencies are achieved using nanocomposite thermoelectric materials. Evenly but thinly dispersing the thermoelectric segments in a matrix of highly insulating material reduces the amount of material required for the segments without sacrificing performance.

  • Publication number: 20140338713
    Abstract: A thermoelectric generator has a heat conducting body that exchanges heat with the environment according to environmental temperature changes, a heat storing body, and a thermoelectric conversion unit and thermal resistance body arranged between the heat conducting body and the heat storing body. One end of the thermal resistance body and one end of the thermoelectric conversion unit are in contact with each other. The other end of the thermal resistance body is in contact with the heat conducting body, and the other end of the thermoelectric conversion unit is in contact with the heat storing body. The surface of the heat storing body is covered by a covering layer having certain heat insulation properties. The temperature difference generated between the heat conducting body and the heat storing body is utilized to extract electric energy from the thermoelectric conversion unit.
