Abstract
A motor vehicle combined heat exchanger has a tube bank linked to two manifolds and divided into an oil cooler having tubes for oil, and a condenser having tubes for a cooling fluid. The two types of tubes are different and possess respective hydraulic diameters related by the following inequality:0.8 mm2≦DHa×DHb≦3.00 mm2where the hydraulic diameter (DH) of a tube is defined by the formula DH=4S/P, in which S designates the area of the internal cross-section of the tube (expressed in mm2) and P the internal perimeter, or “wet perimeter”, of the tube (expressed in mm).
