Abstract
An ejector for a sealed system includes a motive liquid passage with a converging section, a throat and a diverging section. The throat of the motive liquid passage is disposed between the converging section of the motive liquid passage and the diverging section of the motive liquid passage. The ejector also includes a plurality of nucleation sites at the converging section of the motive liquid passage.

An ejector for a sealed system, comprising
- an ejector body integrally formed of a unitary piece of material, the ejector body defining a suction gas passage and a motive liquid passage,
- wherein the motive liquid passage of the ejector body includes a converging section, a throat and a diverging section, the throat of the motive liquid passage disposed between the converging section of the motive liquid passage and the diverging section of the motive liquid passage, the ejector body also defining a plurality of nucleation sites at the converging section of the motive liquid passage.
An ejector for a sealed system, comprising
- an ejector body defining a mixing chamber;
- a nozzle disposed within ejector body proximate the mixing chamber of the ejector body, the nozzle defining a motive liquid passage, the motive liquid passage of the nozzle having a converging section, a throat and a diverging section, the throat of the motive liquid passage disposed between the converging section of the motive liquid passage and the diverging section of the motive liquid passage, the nozzle also defining a plurality of nucleation sites at the converging section of the motive liquid passage.
A method for forming a unitary ejector of a sealed system, comprising:
- establishing three-dimensional information of the unitary ejector;
- converting the three-dimensional information from said step of establishing into a plurality of slices;
- and
- additively forming each slice of the unitary ejector,
- wherein, after said step of additively forming, the unitary ejector comprises an ejector body defining a suction gas passage and a motive liquid passage, the motive liquid passage of the ejector body having a converging section, a throat and a diverging section, the throat of the motive liquid passage disposed between the converging section of the motive liquid passage and the diverging section of the motive liquid passage, the ejector body also defining a plurality of nucleation sites at the converging section of the motive liquid passage.
