Abstract

A receiver tank includes a container extending vertically along one of two spaced opposed header pipes of a condenser, a guide pipe extending from a lower end of the one header pipe into the internal space in the container and further extending upwardly within the container, the guide pipe having a number of perforations at an upper portion thereof for guiding a refrigerant into the container, and a refrigerant outlet pipe connected at a lower end portion of the container for discharging the refrigerant from the container. The guide pipe is inserted into the container from the bottom end thereof and guides the refrigerant from the condenser into an upper part of the container. The receiver tank having such guide pipe and container is easy to assembly. The refrigerant flows out from perforations formed at the upper portion of the guide pipe and then falls down toward the bottom of the receiver tank so that a vapor-liquid separation process can be performed efficiently.

Claims11

Dependent claims

A liquid refrigerant receiver tank for use with a refrigerant condenser, the condenser having a pair of spaced opposed vertical header pipes interconnected in fluid communication by a plurality of horizontal tubes, and a fin disposed between each adjacent pair of tubes, the condenser receiving a gaseous refrigerant and passing it therethrough and condensing it into a liquid and finally collecting the condensed liquid refrigerant in a lower part of one of the header pipes, said receiver tank comprising:

a substantially tubular container disposed vertically along and beside the outside of the one header pipe;
a liquid refrigerant guide pipe extending from the lower part of the one header pipe into said container and further extending upwardly within said container along the length thereof, said guide pipe including an upper portion disposed within said container and having a number of perforations, said guide pipe conducting liquid refrigerant from one header pipe into said container and introducing it into the interior of said container through said perforations;
and
a liquid refrigerant outlet pipe connected at one end thereof with a lower end portion of said container for discharging the liquid refrigerant from said lower end portion of said container.
