In order to provide a heat pipe for transporting heat from an evaporation area to a condensation area, comprising a housing with housing walls, a capillary structure arranged in the housing and thermally coupled to the respective, corresponding housing wall in the evaporation area as well as in the condensation area, a vapor channel arranged in the housing and leading from the evaporation area to the condensation area as well as a heat transport medium, as well to make available a process for the production of such a heat pipe it is suggested that the capillary structure be an open- pored capillary layer produced by way of thermal plasma spraying of powder particles.
L'invention vise à mettre au point un tube échangeur de chaleur (10) servant à acheminer de la chaleur entre une zone de vaporisation (22) et une zone de condensation (24), qui comprend un boîtier (12) avec des parois, une structure capillaire (20) disposée dans ledit boîtier (12) en couplage thermique, dans la zone de vaporisation (22), comme dans la zone de condensation (24), avec la paroi de boîtier correspondante, un canal de passage de vapeur (32) monté dans le boîtier (12) et menant de la zone de vaporisation (22) à la zone de condensation (24). L'invention vise également à mettre au point un milieu caloporteur, ainsi qu'un procédé permettant de produire un tube échangeur de chaleur (10) de ce type. A ces fins, il est prévu que la structure capillaire (20) soit une couche capillaire à pores ouverts produite par projection plasma thermique de particules pulvérulentes.
