Abstract
An improved thermoelectric heat exchanger is provided which comprises a series of thermoelectric units sandwiched between two channels for the purpose of transferring heat from a liquid coolant flowing through one channel to a second fluid flowing through the other channel. Heat transfer fins are brazed to the inner surfaces of both channels to provide improved heat transfer between the fluids and the channels. A thermally conductive grease or ductile metal between the thermoelectric units and the channels provides improved heat transfer at this interface. When an electric current is passed through the thermoelectric units, heat is transferred from the liquid coolant through the thermoelectric units to the second fluid via the Peltier Effect.
