Patent ID: 8408284

Claim:
A heat exchanger assembly, comprising: an inlet header defining an inlet cavity extending along an inlet header axis, wherein the inlet header defines a first opening at a first end of the inlet header, wherein said inlet header further comprises an inlet header end cap, wherein the inlet header end cap is sealably engaged within the first opening in order to define an inlet header end cavity outside of the inlet cavity; an outlet header defining an outlet cavity extending along an outlet header axis, wherein the outlet header defines an opening oriented substantially perpendicular to the outlet header axis; a heat exchanger core including a plurality of refrigerant tubes each extending along a refrigerant tube axis between the outlet cavity and the inlet cavity, wherein the outlet cavity and the inlet cavity are in fluidic communication through the plurality of refrigerant tubes; an outlet conduit segregating the outlet cavity into a return region and an outlet region for influencing a flow therebetween, wherein the outlet conduit defines a plurality of outlet orifices that establish fluidic communication between the return region and the outlet region; and an outlet tube sealably coupled to said opening and extending into the outlet region of the outlet cavity, wherein the outlet tube and the outlet region cooperate to reduce a temperature value range across the heat exchanger core, wherein an outlet tube end located within the outlet region defines a sharp edged entrance, wherein the sharp edged entrance induces a pressure difference between the outlet cavity and the outlet tube when refrigerant flows from the outlet cavity into the outlet tube that influences the temperature value range.
