Patent attributes
Disclosed is a swirl generator for an evaporator, having: a body that extends along a body-center axis between opposing inlet and outlet ends, and includes: a fluid inlet at the inlet end; an outer surface that, at that the outlet end, defines an outlet region with a curved outer boundary forming a convex curve that extends radially inward from an outer diameter surface of the body to an outer axial surface of the body; a center passage formed within the body that extends from the inlet towards the outlet along the body-center axis; and a swirl passage formed at the outlet end of the body, the swirl passage extending between the center passage and the curved outer boundary along a swirl passage axis, whereby a fluid entering from the inlet exits the body at the curved outer boundary, the swirl passage axis forming an acute angle with the body-center axis.
