Title
(EN) HIGH-PERFORMANCE TOOL COOLING SYSTEM
(FR) SYSTÈME DE REFROIDISSEMENT D'OUTILS HAUTES PERFORMANCES
Abstract
(EN) A shaping tool (10, 110) includes a cooling system (12) having one or more cooling passages (26, 126) configured for enhanced cooling. The cooling passages provide latent heat cooling of a heated material that is in contact with a shaping surface (24, 124) of the tool. Cooling fluid flows along the cooling passages in a two-phase flow regime in which a portion of the cooling fluid is liquid and a portion of the cooling fluid is vapor. A two-phase portion (28, 128) of the cooling passage can be shaped to follow a three-dimensional contour of the shaping surface. Opposing walls of the cooling passage can be provided by passage surfaces (42, 44, 142, 144) of separately formed pieces of the tool. The latent heat cooling provided by suitably configured cooling channels extracts more heat from the material being shaped in the tool than traditional cooling systems.
(FR) Un outil à façonner (10, 110) comprend un système de refroidissement (12) ayant un ou plusieurs passages de refroidissement (26, 126) conçus pour un refroidissement amélioré. Les passages de refroidissement assurent un refroidissement de la chaleur latente d'un matériau chauffé qui est en contact avec une surface à façonner (24, 124) de l'outil. Le fluide de refroidissement s'écoule le long des passages de refroidissement selon un régime d'écoulement diphasique dans lequel une portion du fluide de refroidissement est liquide et une portion du fluide de refroidissement est sous forme vapeur. Une portion diphasique (28, 128) du passage de refroidissement peut être façonnée de façon à suivre un contour tridimensionnel de la surface à façonner. Des parois opposées du passage de refroidissement peuvent être pourvues de surfaces de passage (42, 44, 142, 144) de pièces séparément formées de l'outil. Le refroidissement de la chaleur latente réalisé par des canaux de refroidissement convenablement configurés extrait plus de chaleur, du matériau en cours de façonnage dans l'outil, que les systèmes de refroidissement traditionnels.
