ABSTRACT:
A water box (10) and an expansion chamber (11) for a heat exchanger, in particular for a radiator in a motor vehicle, form a single structrue. The expansion chamber (11) and the water box (10) are interconnected by a degassing conduit (24-27) which injects a mixture of gas and liquid substantially tangentially into the expansion chamber. The expansion chamber has a suction orifice (14) through which liquid is drawn into the heat exchanger circuit. Means (35) are provided in the expansion chamber to slow down or prevent rotational motion of the liquid inside the expansion chamber in the vicinity of the suction orifice (14). This serves to reduce the amount of gas that is accidentally entrained into the liquid circuit from the degassing conduit.
