CA 2513211

A cooling system for the cooling of tool pieces (1) is disclosed, operating by means of a cooling fluid running from a fluid inlet (2) to a fluid outlet (3) through connecting lines (7, 8), whereby the tool pieces (1) are connected with a through flow to at least one connector line (7, 8) connected to the fluid inlet (2) and at least one other connected to the fluid outlet (3). According to the invention, other tool pieces can also be cooled outside sleeves forming cavities with high efficiency and increase in fluid turbulence, whereby at least one additional connector line (10 - 12) is connected between the at least one connector line (7) connected to the fluid inlet (2) and the at least one connector line (8) connected to the fluid outlet (3) in fluid connection therewith, connected therein such that the fluid flows serially through at least two tool pieces (1) in the fluid path thereof.

L'invention concerne un système de refroidissement permettant de refroidir des parties d'outil (1) au moyen d'un fluide acheminé d'un orifice d'entrée de fluide (2) à un orifice de sortie de fluide (3) par l'intermédiaire de conduits de raccordement (7, 8), lesdites parties d'outil (1) étant raccordées en liaison fluidique entre au moins un conduit de raccordement (7) relié à l'orifice d'entrée de fluide (2) et au moins un conduit de raccordement (8) relié à l'orifice de sortie de fluide (3). L'objectif de cette invention est de permettre le refroidissement de manchons formant des cavités externes ainsi que d'autres parties d'outil avec un rendement accru et lors d'une amplification de turbulences du fluide. A cet effet, au moins un conduit de raccordement supplémentaire (10 12) et des parties d'outil (1) en liaison fluidique avec lesdits conduits sont incorporés entre le conduit de raccordement (7) relié à l'orifice d'entrée de fluide (2) d'une part et le conduit de raccordement (8) relié à l'orifice de sortie de fluide (3) d'autre part, de sorte que le fluide circule successivement à travers au moins deux parties d'outil (1) sur son trajet d'écoulement.
