In a liquid flow heat exchanger, such as the radiator in the cooling circuit for an internal combustion engine in a motor vehicle, the heat exchanger proper comprises a bundle of tubes (10) having at least a first water box (11) mounted at one end thereof and serving as a manifold chamber giving access to the ends of the tubes in the bundle. A passage (20) is provided for degassing the liquid, and the passage passes through the mid portion of the bundle of tubes (10) to connect the first water box (11) to an expansion chamber (16). Preferably the passage includes one of the tubes (21) in the bundle.
