Title (EN) VAPOR CHAMBER WITH THREE-DIMENSIONAL PRINTED SPANNING STRUCTURE
(FR) CHAMBRE À VAPEUR À STRUCTURE DE RECOUVREMENT IMPRIMÉE EN TROIS DIMENSIONS
Abstract:
(EN) A three-dimensional printed vapor chamber device is provided. A chamber from a first surface and a second surface at least partially enclosing a volume includes a spanning structure extending from the first surface to the second surface throughout a region within the volume. A defined gap between the first surface and second surface is maintained by the spanning structure, which also defines a plurality of flow passages. Evaporated working fluid flows from an evaporation region proximate a heat source through looped flow passages to a condensation region at a distal end of the chamber before returning as condensate by way of capillary action to the evaporation region.
(FR) L'invention concerne un dispositif de type chambre à vapeur imprimée en trois dimensions. Une chambre constituée à partir d'une première surface et d'une seconde surface entourant au moins partiellement un volume comprend une structure de recouvrement s'étendant de la première surface à la seconde surface dans toute une région à l'intérieur du volume. Un espace défini entre la première surface et la seconde surface est maintenu par la structure de recouvrement, qui définit également une pluralité de passages d'écoulement. Le fluide de travail évaporé s'écoule d'une région d'évaporation à proximité d'une source de chaleur à travers des passages d'écoulement en boucle vers une région de condensation au niveau d'une extrémité distale de la chambre avant de retourner sous forme de condensat, par capillarité, vers la région d'évaporation.
