Pulsed flow regulating device without rotating parts and cooling structure for nuclear power plant reactor

Abstract

A pulsed flow regulating device without rotating parts, including a water holding container, a water outlet channel and a first water inlet. The regulating device is configured to apply a pulsed flow onto the to-be-cooled wall surface for cooling. External cooling water enters the water holding container through the first water inlet. The water outlet channel has an inverted U-shaped structure, and has a water outlet and a second water inlet. The second water inlet is located within the water holding container. The water outlet extends through a bottom of the water holding container to guide water flow onto the to-be-cooled wall surface. A cross-sectional area of the water holding container is greater than that of the water outlet channel. A cooling structure for a nuclear power plant reactor is also provided.
