Abstract: A heat transfer device includes a sleeve, which forms an interior in which a working medium and one vaporization element having structural elements, or multiple vaporization elements having structural elements, for converting at least part of the working medium from the liquid to the gaseous state are contained, wherein the vaporization element or the vaporization elements has or have a porosity, and is or are connected to the sleeve.

Abstract: A method for producing a heat pipe includes the steps: providing a pipe-shaped casing element having a length and an interior; filling a powder with particles into the casing element to form a capillary structure in the casing element; connecting the particles of the powder to one another, wherein the interior enclosed by the casing element is filled with the powder partially or in its entirety at least across a partial area of the length of the casing element, and subsequently the connection of the particles of the powder to one another and preferably also to the casing element in a layer lying against the casing element is established from the outside by inductive heat generation.
