  • Patent number: 9660168
    Abstract: A thermoelectric power generator for converting thermal energy into electrical energy. The thermoelectric power generator includes a heat exchanger configured to extract thermal energy from an exhaust gas stream. The heat exchanger includes fins in contact with a boundary of the heat exchanger, where the fins are directly connected to a first set of thermoelectric modules. A second set of thermoelectric modules are directly connected to the boundary of the heat exchanger. The first and second sets of thermoelectric modules are configured to convert the thermal energy to electrical energy. By eliminating the metal wall that previously existed between the thermoelectric modules and the fins, the thermoelectric power generator improves the heat transfer between the exhaust gas and the thermoelectric modules, eliminates the thermal fatigue failures at the bond between the metal wall and the thermoelectric modules as well as allows for a higher density of thermoelectric modules.

  • Patent number: 8726976
    Abstract: A heat exchanger can have a manifold which includes a plurality of laminated sheets that allow a customization of the heat exchanger. The design can allow for a more optimal flow of coolant to areas of high load, thereby making the temperature distribution across the heat exchanger more uniform, or intentionally non-uniform. Furthermore, the laminated sheets can allow multiple circuits to be employed in the heat exchanger such that different coolants can be utilized therein and maintained separate from one another. The tubes can be microchannel tubes. A single set of manifolds can be used with multiple heat exchanger cores to provide a more compact heat exchanger. Mounting features can be integral with a group of the sheets.

  • Publication number: 20140041842
    Abstract: A heat exchange chamber includes an inlet, an outlet and a plurality of walls defining a chamber interior. The inlet receives a heat exchange medium flowing in a first flow direction in an initial line of flow. Disposed within the chamber interior is a medium directing member, having an inclined surface, which diverts the medium from the initial flow direction so that it disperses within the chamber interior. Exposure to the contact surfaces provided by the chamber walls causes the medium to exchange heat with the chamber and the external environment. The medium exits the chamber, via the outlet, in the initial line of flow. The chambers are interconnected by tubes to form assemblies. Plural sets of chamber and tube assemblies are arranged between manifolds to provide a heat exchanger.
