Abstract

The present invention relates to a passive pulse water flow adjustment device for water flow cooling. The device includes a water storage container and a pulse water flow adjustment structure, wherein the water storage container is arranged in front of a to-be-cooled high-temperature wall surface through the pulse water flow adjustment structure, and the pulse water flow adjustment structure provides a non-continuous pouring pulse water flow for the high-temperature wall surface. This device is used to cool the high-temperature wall surface, and when being cooled, the high-temperature wall surface is poured by the pulse water flow.

First claim
