Abstract

La présente invention se rapporte à un dispositif gicleur permettant de conférer une quantité de mouvement importante à un fluide composite, gazeux ou liquide, par exemple pour le projeter sur une surface déterminée, aux fins de refroidissement. Le dispositif est caractérisé en ce qu'il est constitué d'un conduit central dont le profil en long est celui d'une tuyère de Laval, avec un diamètre de col compris entre 0,7 mm et 2 mm, et d'au moins un conduit latéral débouchant dans le conduit central vers l'extrémité de sa partie divergente ou à la sortie de ce conduit central, en ce que les axes de pénétration de ces conduits latéraux dans le conduit central sont inclinés sur l'axe longitudinal dudit conduit central dans le sens de l'écoulement des fluides, leur inclinaison étant supérieure à 30 degrés et de l'ordre de 45 degrés . Application au refroidissement, notamment.The present invention relates to a nozzle device making it possible to impart a large quantity of movement to a composite fluid, gaseous or liquid, for example to project it onto a determined surface, for cooling purposes. The device is characterized in that it consists of a central duct whose longitudinal profile is that of a Laval nozzle, with a throat diameter of between 0.7 mm and 2 mm, and at least a lateral duct opening into the central duct towards the end of its diverging part or at the outlet of this central duct, in that the axes of penetration of these lateral ducts into the central duct are inclined on the longitudinal axis of said central duct in the direction of flow of the fluids, their inclination being greater than 30 degrees and of the order of 45 degrees. Application to cooling, in particular.
