Abstract

A distribution device (5) for a liquid-vapor two-phase fluid for a heat exchanger, comprising an inlet duct (6) and a section (7) provided with a plurality of outlet ducts (7a, 7b, 7n) for the liquid-vapor two-phase fluid. The inlet duct (6) comprises a first duct section (6A) and a second duct section (6B) arranged in sequence along the flow direction (F) of the liquid-vapor two-phase fluid through the distribution device (5). The first duct section (6A) has a uniform cross-section and is provided with a plurality of turbulator elements (8a, 8b, 8c, 8d) designed to cause pre-mixing of the liquid phase and vapor phase of the two-phase fluid. The second duct section (6B) has a progressively converging and diverging Venturi-shaped cross-section designed to cause remixing of the liquid phase and vapor phase of the two-phase fluid. The device of the invention offers the advantage of both dividing the two-phase fluid into equal flows in all the supply ducts to the heat exchanger and achieving complete mixing and uniform homogenisation of the liquid phase and the vapor phase in all the supply ducts of the two-phase fluid.
