Patent number: 10876771Abstract: 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).Type: GrantFiled: July 5, 2018Date of Patent: December 29, 2020Assignee: Ferrotec (USA) AmericaInventors: Robert Otey, David A. Kaminski, Pheng Sin

Patent number: 9929331Abstract: 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 transversely from the first impeller body and away from the second impeller body. Impeller vanes extend transversely 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 one or more thermoelectric modules.Type: GrantFiled: April 19, 2014Date of Patent: March 27, 2018Assignee: Ferrotec (USA) CorporationInventors: Robert Otey, David A.
