Thermoelectric devices utilizing double-sided Peltier junctions and methods of making the devices
A thermoelectric device and method of manufacturing the device, where thermoelectric elements of opposite conductivity type are located on respective opposing sides of a heat source member. Heat sinks are disposed on opposite sides of the thermoelectric elements. Peltier metal contacts are positioned between the thermoelectric elements and each of the heat source member and heat sinks. A plurality of devices may be arranged together in a thermally parallel, electrically series arrangement, or in a thermally parallel, electrically parallel arrangement. The arrangement of the elements allow the direction of current flow through the pairs of elements to be substantially the same as the direction of current flow through the metal contacts.
