Water-tube heat exchanger for a motor vehicle air-conditioning system, having a header with a baffle for dividing the flow.

摘要

A water-tube radiator for a motor-vehicle air-conditioning system includes a header with a cover (16) of polymeric material welded ultrasonically to a flow-dividing baffle (20) with a flat base portion (20a) which faces the tube plate (is) with the interposition of a flat gasket (22) of elastomeric material. The base portion (20a) of the baffle (20) has a plurality of U-shaped connectors (27) arranged to cause the liquid to pass tube-side more than twice without the need for more than one flow-dividing baffle.
