Abstract: A fluid heat exchanger has an impeller assembly with first and second impeller bodies mated together, each having a substantially circular shape and at least one opening therethrough. Impeller vanes extend axially from the first impeller body and away from the second impeller body. Impeller vanes extend axially from the second impeller body away from the first impeller body. A thermoelectric module is disposed between the first impeller body and the second impeller body. Heat sinks are connected to each side of the thermoelectric module and extend through at least one opening in the first and second impeller bodies, where the impeller vanes are configured to move a fluid through the heat sinks during rotation of the first and second impeller bodies. Electrically-conductive windings disposed in the impeller assembly are configured to deliver induced electric current to the thermoelectric module(s).

Abstract: A fluid heat exchanger has a housing having a thermally conductive base, a plurality of fin members connected to the base in a parallel, spaced relationship, a heat exchanger fluid inlet on one side of the plurality of fin members, and a heat exchanger fluid outlet on the opposite side of the plurality of fin members. The plurality of fin members each have a plurality of passageways and are arranged in the housing so that the passageways of one fin member are offset from the passageways of adjacent fin members.

Abstract: A thermoelectric device with an improved thermal efficiency has an object to be heated or cooled having a surface, at least one electrically conductive lower pad bonded directly to the surface of the object using a thermally conductive dielectric material, at least one thermoelectric element coupled on one end to the electrically conductive pad, at least one electrically conductive upper pad coupled to an opposite end of the thermoelectric element, and electrical power connections coupled to the device.

Abstract: The electrical junctions of either or both sides of a thermoelectric module are placed in direct thermal contact with a heat source or sink or a material to be thermally modified (that is, heated or cooled), thereby eliminating the conventional substrate typically found in such modules and its associated thermal resistance. In one embodiment, the conductive junction passes through a conduit carrying a material to be heated or cooled. In the conduit, the conductive material can be configured into an effective heat transfer shape such as a vane which extends through non-conducting conduit walls. In another embodiment, the geometry of the conductor forming the electrical junction forms a pipe or tube through which material to be heated or cooled is passed. A protection layer of high thermal conductivity can be applied to the conductive surfaces in order to prevent corrosion or short-circuiting of the device in applications where an electrolytic or ionic fluid is passed by the junction.
