  • Publication number: 20130103125
    Abstract: The invention discloses a device composed of PCM and of an actively cooling heat-exchanger system whose use in humans and animals reliably solves the previous problem of temperature build-up. The system can be configured in any strength, that is to say ranging from integration in flexible stockings to integration in orthosis stumps. This results in the extremely varied areas of application of the described technology, which range from PCMs in the form of modules in coolant channels or in the form of PCM-containing compounds, from which hoses are produced in which coolant can flow, to PCMs with heat exchangers that remove the built-up heat of the body.

  • Patent number: 8262925
    Abstract: The invention relates to a method for producing a low-exuding preferably non-exuding polymer-bonded phase-change material composition containing phase-change material, characterized in that the phase-change material is liquefied, the liquid phase-change material is introduced into an extruder at a temperature of between 50° C. and 130° C., however at least 20° C. to 70° C. above the melting point of the phase-change material into which the polymer is also introduced, wherein the extruder comprises mixing transport and holder elements and the introduction of the phase-change material into the extruder in the extrusion direction is performed after the polymer.
