GLAS TUBE WITH INFRARED LIGHT REFLECTIVE COATING, METHOD FOR MANUFACTURING THE GLASS TUBE HEAT RECEIVER TUBE WITH THE GLASS TUBE, PARABOLIC TROUGH COLLECTOR WITH THE HEAT RECEIVER TUBE AND USE OF THE PARABOLIC TROUGH COLLECTOR

摘要

A glass tube with a glass tube wall is provided, wherein an inner surface of the glass tube wall comprises at least partially at least one infrared light reflective coating. Additionally a heat receiver tube for absorbing solar energy and for transferring absorbed solar energy to a heat transfer fluid, which can be located inside a core tube of the heat receiver tube, is provided. The core tube comprises a core tube surface with a solar energy absorptive coating for absorbing solar absorption radiation of the sunlight. The core tube surface and an encapsulation are arranged in a distance between the core tube surface and the inner surface of the encapsulation wall with the infrared reflective surface such, that the solar absorption radiation can penetrate the encapsulation with the infrared light reflective coating and can impinge the solar energy absorptive coating.
