Abstract

The present disclosure relates to a method for cooling a component of a glass melting plant that contacts a glass melt, the corresponding cooling device, as well as the system of the cooling device and the cooled component itself. The method provides that a pipe with an open pipe end at least on one pipe section is introduced into an open cavity in the component with the formation of a peripheral annular space, and a cooling medium is introduced through the pipe into the cavity and is deflected at the base of the cavity, flows back in the annular space, and flows out of the cavity. In its pipe section introduced into the cavity, the pipe has a constriction and has perforations through the pipe walls in the region of the constriction, whereby the cooling medium is accelerated in its passage through the constriction in the inside of the pipe, and a portion of the cooling medium flowing back from the annular space is aspirated into the inside of the pipe.
