Distributor apparatus for fluid including a gaseous and liquid phase.

摘要

An apparatus (20) for uniformly distributing a fluid including gaseous and liquid phases for use with a heat exchanger is disclosed. A liquid spreading device of the apparatus includes a main pipe (22) extending along the full length of a header of the apparatus, and a plurality of branch pipes (24) connected to the main pipe (22) and extending perpendicularly to the main pipe (22) just above and along the full width of downward flow inlets (5) of a core of the heat exchanger. Each branch pipe (24) has a plurality of liquid spreading holes (25) perforated in a predetermined spaced relationship at the bottom thereof. Thus, liquid can be distributed from the apparatus substantially uniformly within a deviation of, for example, plus or minus 10 percent.
