The invention relates to a motor vehicle heat exchanger system with a closed circuit for a working medium. The automotive heat exchanger system comprises an exhaust duct 3 for the passage of exhaust gas that is discharged from an internal combustion engine of the motor vehicle. An evaporator 1 makes contact with the exhaust gas passage 3. In the evaporator 1, the working medium is evaporated. According to the invention, the evaporator 1 comprises at least one evaporator cassette 4, 5, wherein the evaporator cassette 4, 5, a housing and a capillary structure disposed in the housing 7 8. The capillary 8 is formed by a porous sheet body, preferably made of a sintered material.
