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.
Claims9
A heat transfer device comprising 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 wherein the vaporization element is connected to the sleeve or the vaporization elements are connected to the sleeve
- wherein the vaporization element on a side region of the vaporization element facing the sleeve comprises a layer with a smaller porosity as compared to the remaining region of the vaporization element.
A method for producing a heat transfer device comprising the steps:
- providing a sleeve;
- providing one vaporization element with knob-shaped structural elements or multiple vaporization elements with knob-shaped structural elements;
- filling a liquid into the sleeve;
- and
- pressure-tight closing and reduction of the pressure in the interior of the sleeve;
- wherein the vaporization element or the vaporization elements are connected to the sleeve;
- and
- wherein the vaporization element on a side region of the vaporization element facing the sleeve comprises a layer with a smaller porosity as compared to the remaining region of the vaporization element.
