Solar absorber module and solar absorber arrangement

Abstract

The invention relates to a solar absorber module (2, 2') comprising a housing (20, 20') that has a longitudinal axis (L), a first tapered housing section (21, 21') with a first free end (22) and a second end (23) which has a smaller cross-sectional area than the first end (22), and a second housing section (24, 24') which adjoins the second end (23) of the first housing section (21, 21') and has a substantially constant cross-section along its length. The solar absorber module (2, 2') further comprises a ceramic solar absorber element (30, 30') which is accommodated at the first end (22) of the first housing section (21, 21') and includes a first surface (31) that can be oriented towards the solar radiation and has an axis of symmetry (S), and a second surface (3) lying across from the first surface (31).; The solar absorber element (30, 30') has a plurality of substantially straight ducts (33) connecting the first surface (31) to the second surface (32). According to the invention, the solar absorber module is characterized in that the same is accommodated at the first end (22) of the first housing section (21, 21') in such a way that the axis of symmetry (S) of the first surface (31) is inclined relative to the longitudinal axis (L) of the housing (2, 2').

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...

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
