Abstract

A motor vehicle heat exchanger for independently heating different passenger areas comprising first and second tube/fin block units for transferring heat from coolant flowing through tubes thereof to air flowing therethrough to first and second passenger areas, respectively. Common upper and lower coolant reservoir tanks supply coolant to both tube/fin units and receive coolant returning therefrom respectively. Intake tubes extend through a common gap between the first and second tube/fin units to supply heated coolant to the lower cooling tank.
