ABSTRACT:
An improved demisting screen arrangement utilized in a rotary fluid management device (13) of a two-phase thermal management system (1) employs a multi-layered annular screen (34) held in a casing (52) to define a space (54) on the downstream side of the screen (34). The arrangement provides a lower pressure drop across the screen which results in wet vapor passing through the screen (34) at a lower velocity and in thereby preventing the vapor from passing through only a localized section near the inner diameter of the annular screen (34) in the region of the hub (56). This arrangement effectively increase the volume of the screen (34) through which the wet vapor is now caused to flow and, therefore, increases the amount of liquid phase separated from the vapor phase.
