ABSTRACT:
A heat exchanger, typically a cooling radiator for an internal combustion engine of a motor vehicle, has a water header with an integral expansion chamber. The header comprises a header body or casing having an elongated open bottom face closed by a header plate, which is fixed to the header body. Liquid flows in the header between a first end and a second end of the latter, so as to cover the header plate. The header body has a set of transverse, integral baffles spaced apart along the header body between its two ends. Each baffle has a free edge close to the header plate and an opening defining a flow cross section through the baffle. The area of this opening decreases in successive baffles in the direction of flow.
