Abstract
A helical jet impingement evaporator including a laminated evaporator core comprising a plurality of orifice plates (1) each including a plurality of jet impingement orifices (5) for enabling a passage of a first fluid therethrough on a single-phase side of the evaporator. A plurality of spacer plates (2) are interposed between adjacent orifice plates (1) and the orifice plates (1) and spacer plates (2) are stacked with adjacent orifice plates (1) and spacer plates (2) being offset with respect to each other in a circumferential direction. The orifice plate (1) include circumferentially and radially spaced elongate slots (7, 9, 11) in registry with elongated slots (8, 10, 14) in the spacer plates (2) so as to define separate helical two-phase evaporating flow paths for a second fluid on a two-phase side of the evaporator.
