Claim Text:
1. A thermoelectric generator unit which comprises: an exhaust gas heat exchanger, said exhaust gas heat exchanger including first and second flat side walls haying corresponding first and second ends, and first and second lateral walls, said first lateral wall extending between said first ends of said first and second flat side walls and said second lateral wall extending between said second ends of said first and second side walls to define a generally flat first duct, a coolant heat exchanger, said coolant heat exchanger including third and fourth flat side walls having corresponding first and second ends, and third and fourth lateral walls, said third lateral wall extending between said first ends of said third and fourth flat side walls and said fourth lateral wall extending between second ends of said third and fourth flat side walls to define a generally flat second duct, said first and second generally flat ducts extending parallel to each other, a thermoelectric module having opposite first and second surfaces positioned between said exhaust gas and coolant heat exchangers, said thermoelectric module including a series of p- and n- doped legs, and a first side wall which is directly attached to and between said first lateral wall of said exhaust gas heat exchanger and said third lateral wall of said coolant heat exchanger, and a second side wall which is directly attached to and between said second lateral wall of said exhaust gas heat exchanger and said fourth lateral wall of said coolant heat exchanger to clamp together said first duct, said thermoelectric module and said second duct and thereby form a compressed sandwiched unit.
