Abstract[English]
A two-phase heat transfer arrangement (1) comprising a fluid (3) for thermal transfer and a closed-loop fluid path (4) containing the fluid (3) . The closed-loop fluid path (4) comprises an evaporator (5) generating a fluid phase change from liquid phase to gaseous phase, a condenser (7) generating fluid phase change from gaseous phase to liquid phase, a compensation chamber (8) comprising a liquid phase fluid reservoir, at least one gaseous phase conduit (9) conveying gaseous phase fluid from the evaporator (5) to the condenser (7) , at least one liquid phase conduit (10) conveying liquid phase fluid from the condenser (7) to the compensation chamber (8) . The closed-loop fluid path (4) further comprises a capillary element (11) comprising capillary material soaked with liquid phase fluid (3) , the capillary element (11) comprising a plurality of tapered grooves (12) conveying gaseous phase fluid in a direction towards the gaseous phase conduit (9) .[French]
L'invention concerne un agencement de transfert de chaleur à deux phases (1) comprenant un fluide (3) pour le transfert thermique et un trajet de fluide en boucle fermée (4) contenant le fluide (3). Le trajet de fluide en boucle fermée (4) comprend un évaporateur (5) générant un changement de phase fluide de la phase liquide à la phase gazeuse, un condenseur (7) générant un changement de phase fluide de la phase gazeuse à la phase liquide, une chambre de compensation (8) comprenant un réservoir de fluide en phase liquide, au moins un conduit de phase gazeuse (9) transportant le fluide en phase gazeuse de l'évaporateur (5) au condenseur (7), au moins un conduit de phase liquide (10) transportant le fluide en phase liquide du condenseur (7) à la chambre de compensation (8). Le trajet de fluide en boucle fermée (4) comprend en outre un élément capillaire (11) comprenant un matériau capillaire imbibé de fluide en phase liquide (3), l'élément capillaire (11) comprenant une pluralité de rainures coniques (12) transportant un fluide en phase gazeuse dans une direction vers le conduit de phase gazeuse (9).
