Summary:Disclosed is a heat pipe with a wick structure containing pipe type continuous air holes, produced by positioning a tool at a center of the pipe and multiple wires (6) at a position attached to an inner wall of the pipe, respectively; charging metal powder between the inner wall of the pipe and the tool (5); sintering the resulting structure in a furnace under a reducing atmosphere at 700 to 1000 DEG C for 10 to 180 min to attach a sponge type wick with fine air holes to the inner wall of the pipe; removing the tool and wires to form the wick structure with pipe type continuous air holes; charging a working fluid into the inside of the pipe under vacuum; and sealing the pipe. L'invention concerne un caloduc avec une structure de mèche contenant des trous d'air continus. Le procédé de fabrication de ce caloduc consiste à placer respectivement un outil au centre dudit caloduc et de multiples fils (6) au niveau d'une position en contact avec une paroi intérieure du caloduc, à charger une poudre métallique entre la paroi intérieure du caloduc et l'outil (5), à fritter la structure résultante dans un four dans une atmosphère de réduction comprise entre 700 et 1000 DEG C pendant 10 à 180 minutes afin de fixer une mèche de type éponge avec de petits trous d'air sur la paroi intérieure du caloduc, à retirer l'outil et les fils pour former la structure de mèche avec des trous d'air continus de type tuyaux, à charger un fluide de travail à l'intérieur du caloduc sous vide, et à fermer hermétiquement le caloduc.
