An oil/water heat exchanger for a motor vehicle has an inlet tube branch and an outlet tube branch joined to the body of the heat exchanger. Each of these tube branches has a bent portion close to the heat exchanger body. The transverse cross section of the bent portion is flattened (elongated), with its minor dimension extending in the direction of the radius of curvature of the longitudinal axis of the tube branch. This enables this radius, and therefore also the amount by which the tube branches project from the tube body, to be reduced for a given fluid passage cross sectional area.
