Problems solved by technology

The double-walled construction of the metallic holding tube of the load-bearing structure proves to be disadvantageous in that the inner tube (which accommodates the absorption module) can only be welded at the rear end.
During operation due to temperature-varying loads, the load-carrying structure can distort, whereby the gap width between the absorber modules changes unfavorably

Embodiment Construction

[0044] As shown in FIG. 1 , a solar absorber module 8 ′ known from the prior art comprises a housing 80 ′ with a longitudinal axis L, which comprises, on its side, a first free end 82 ′ and a second end 83 ' (it has the cross-section that reduces with respect to first end 82 ') and the second shell that has substantially constant cross-section on its longitudinal extension Body section 84'. Furthermore, as can be seen in FIG. 1 , the second housing section 84 ′ is directly connected to the second end 83 ′ of the first housing section 83 ′, so that the housing 80 ′ overall has the shape of a funnel.

[0045] The solar absorber element 9 ′ is accommodated in the free end 82 ′ of the first housing section 81 ′, the solar absorber element 9 ′ is now approximately rectangular in design and in its part pointing into the interior of the housing 80 ′ There are frustum pyramids 91 ′ at the surface.

[0046] The solar absorber element 9' of a ceramic material, preferably SiC or silico...

Abstract

A solar absorber module is described. The module has a housing with a longitudinal axis with a first tapered housing section with a first, free end, and a second end with a reduced cross-sectional area compared to the first end, and with a second housing section adjoining the second end of the first housing section with a substantially constant cross-section over its length. The module also has a ceramic solar absorber element accommodated in the first end of the first housing section with a first surface that can be oriented toward the solar radiation with an axis of symmetry, and a second surface lying across from the first surface, wherein the solar absorber element has a large number of substantially straight channels connecting the first surface to the second surface. The solar absorber module is accommodated in the first end of the first housing section such that the axis of symmetry of the first surface is inclined relative to the longitudinal axis of the housing.

Description

technical field [0001] The invention relates to a solar absorber module comprising a housing with a longitudinal axis (which has a conical first housing section with a first free end and a a second end of reduced cross-sectional area at one end; and a second housing section coupled to the second end of the first housing section, the second housing section having a longitudinal extension at its substantially constant cross-section) and a ceramic solar absorber element housed in a first end of a first housing section (with a first surface having an axis of symmetry oriented toward solar radiation and facing the first a second surface of the surface), wherein the solar absorber element has a plurality of conduits extending substantially straight connecting the first surface with the second surface. Furthermore, the invention relates to a method for producing a housing of a solar absorber module and a solar absorber assembly. Background technique [0002] A solar thermal power...
