Fuel-cooled flexible heat exchanger with thermoelectric device compression

摘要

An apparatus includes a thermoelectric (TE) device (82), a gas flow conduit (80) proximate to one side of the thermoelectric device, a plurality of flexible tubes (84) proximate to a second side of the thermoelectric device, and a spring (86) to control contact force between the flexible tubes and the thermoelectric device. The spring comprises a coil spring at least partially circumscribing the gas flow conduit. The thermoelectric device converts a temperature differential between the flexible tubes and the gas flow conduit into electrical energy.
