Abstract
Apparatus for supplying a coherent curtain of cooling liquid comprises a generally rectangular nozzle with an inlet and an outlet, the nozzle being divided into a multiplicity of individual passages extending in the direction between the inlet and the outlet, a header for introducing liquid coolant to the inlet of the nozzle and a slider displaceable beneath the passages to close off those above the slider and a body carried at the inwards end of the slider providing further passages constituting extensions to those above them and the outer ones of the further passages are inclined outwardly to cause the curtain to diverge as it leaves the nozzle.
Claims9
A cooling apparatus for supplying a continuous curtain of cooling liquid comprising:
- (a) a nozzle having
- (i) an inlet being in elongate generally rectangular form,
- (ii) an outlet being in elongate generally rectangular form and having a considerably narrower cross-section area than said inlet,
- (iii) an intermediate portion located between said inlet and the outlet and containing division means for dividing the interior of that portion of said nozzle into a multiplicity of individual but contiguous first passages extending in the direction between said inlet and said outlet,
- (b) a header tank for receiving liquid coolant, in which at least the inlet of the nozzle is located, and wherein said outlet of the nozzle communicates with the outside of said header tank, and
- (c) a slider displaceable beneath said first passages from one end of the nozzle to close off those of the first passages beneath which it extends, and means positioned at the inward end of the slider which provides a group of individual but contiguous second passages which serve as extensions to those of the first passages below which they are positioned, and those of said second passages which are positioned adjacent to the slider having their outlet ends inclined outwardly with respect to the other second passages.
