ABSTRACT:
An apparatus for uniformly distributing a liquid having dual gaseous and liquid phases for use with a heat exchanger is disclosed. A liquid spreading device of the apparatus includes a main pipe extending along the full length of a header of the apparatus, and a plurality of branch pipes connected to the main pipe and extending perpendicularly to the main pipe just above and along the full width of descending flow entrances of a core of the heat exchanger. Each branch pipe has a plurality of liquid spreading holes 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, .+-.10 percent.
