Abstract

The distributor is constituted by a simple metal sheet (17) shaped as a spherical calotte that is provided with holes (17b) at its periphery and which is plane at the center. This plane element is preferably delimited by a conical body (17a).

Claims

1. A distributor for the filling of intratubular heat exchangers of cooling installations with a two-phase type refrigerant, of a type to be mounted at the outlet of an inlet tube of the refrigerant inside a chamber (6) that fills exchange tubes (11), comprising a metal sheet (15, 16, 17) shaped as an pen spherical calotte in a direction toward an outlet of a tube (8) presenting a series of holes (15b, 16b, 17b) arranged around a plane central section (15a, 16a, 17a);

wherein said plane central section is delimited by a flow enhancing structure mounted at a bottom of said spherical calotte.

2. A distributor in accordance with claim 1, wherein said flow enhancing structure is a plane plate (16a).

3. A distributor in accordance with claim 1, wherein said flow enhancing structure is a conical-shaped body (17a) having a point which is inserted into the inlet tube (8).

4. A distributor in accordance with claim 3, wherein said conical-shaped body (17a) is provided at its outside surface with grooves that extend parallel to an axis of said body (17a).
