Problems solved by technology

[0020] In practice, however, this mechanical damage occurs even without mechanical contact due to the air flowing intentionally through and over the seal, which ultimately leads to the problem of actually obtaining differently curved segments The common focal line area and the adjacent pressure area are sealed to the correct degree

Embodiment Construction

[0034] figure 1 Shown is a trough collector 1 of conventional type comprising a mat in the form of an upper flexible membrane 3 and a figure 1 The pressure element 2 is formed by the covered lower flexible membrane 4 . The pressure element 2 is kept under operating pressure by means of a fluid channel 5, wherein a fluid channel 6 is also provided, the function of which is referred to figure 2 A detailed description.

[0035] Membrane 3 is transparent to solar rays 7 which are incident on concentrator membrane 8 inside pressure element 2 ( figure 2 ) and is reflected by the collector film 8 as rays 7' to the absorber tube 9 in which a heat transfer medium circulates and carries away the heat collected by the collector. The absorber tube 9 is held in the focal line region of the collector membrane 8 by a bracket 10 ( figure 2 ).

[0036] The pressure element 2 is clamped in a frame 11 which in turn is mounted on the frame tiltably according to the position of the sun.

Abstract

The solar collector according to the invention has a membrane arrangement 41 comprising zones 70, 71, 72 having different spherical curvature in such a manner that their concentrator membrane 42 which is covered with a reflecting layer is optimally approximated to a parabolic shape and therefore has an optimally small focal point or focal line region.

Description

technical field [0001] The invention relates to a radiation collector according to claim 1 . Background technique [0002] Radiation collectors or radiation concentrators of the described type are used in particular in solar power plants. [0003] Due to the disadvantages of the photovoltaic method which have not yet been overcome, it has not been possible to use this technology to generate solar electricity in a manner which substantially covers the costs. On the other hand, solar thermal power plants have been generating electricity on an industrial scale for some time, at a price which, compared with photovoltaic methods, is close to the present usual commercial price of electricity produced in a conventional way. [0004] In a solar thermal power plant, the solar radiation is reflected by means of a concentrator by means of a collector and is focused specifically at the point at which a high temperature is thereby generated. The accumulated heat can be removed and used...
