Collector tubes on which solar radiation is focussed - are enclosed in vacuum tube or chamber with reflectors

So that an installation can be operated with the maximum of efficiency, the degree of absorption of a collector tube for solar energy is raised as high as possible, and heat losses are reduced to the minimum by having the collector tubes vacuum-insulated over most of their length. The collector tubes which may be of metal or of boron-silicon glass, and may have a black surface layer, are enclosed in a tube of larger dia., transparent to infrared rays, which is evacuated. The outer tube may have over part of its inner periphery, e.g. over an arc enclosing 30-60 degrees an inwards directed mirror surface, whilst bellows joints are fitted to compensate for differences in temp. between outer tube and collector tube.

Use of a glass composition for making a solar collector with a glass-metal joint

A glass composition for a tubular glass body used to form a glass-metal joint in a tubular solar collector. Includes a borosilicate glass having a dilatometric chart with a hard segment and a soft- segment hysteresis.

A heliostat sub-assembly

The invention relates to a heliostat sub-assembly and to a method of forming such a sub-assembly. The method of mounting a concave mirror to a supporting structure of a heliostat includes the steps of bonding a plurality of risers at predetermined spaced intervals to a rear face of the mirror, each riser having a bonding pad and a stem extending from the bonding pad, and applying a predetermined concave curvature to the mirror by conforming the front face of the mirror with a convex forming jig or die. The supporting structure and curved mirror are then aligned, and the supporting structure is clinched to the stems of the risers when the curved mirror is conformed with the forming die. The riser stems may be coupled to the bonding pads via multi-axial joint assemblies to enable limited multi-pivotal movement of the stems relative to the bonding pads to facilitate alignment of faces of the stems with the faces of the ribs defined by webs, and relative expansion and contraction of the mirror and supporting structure, the overlap between the riser stems and the webs being sufficient to accommodate clinching with variations in curvature of the glass sheet.

Panel-shaped solar collector

Die Erfindung bezieht sich auf einen plattenförmigen Sonnenkollektor, bei dem das den Strahlenabsorber (3) enthaltende Gehäuse durch zwei Glasplatten (1 und 2) und einem metallischen Distanzrahmen gebildet wird, der mit den Glasplatten am Rand gasdicht verbunden ist, so daß das Gehäuse evakuiert werden kann. Der Distanzrahmen besteht dabei aus einem relativ verwindungssteifen Metallprofil (7) und aus auf dem Metallprofil angeordneten Nachgiebigen Stegen (8 und 9) aus einem leicht verformbaren Metall. Diese nachgiegigen Stege sind mit dem Metallprofil einerseits und mit den zu diesem Zweck im Randbereich metallisierten Glasplatten andererseits verlötet. Als Metallprofil können vorzugsweise an den Ecken miteinander vakuumdicht verschweißte Vierkantrohrabschnitte verwendet werden, während für die Stege zweckmäßig ein Bleiband verwendet ist. In Abhängigkeit von der Größe der Sonnenkollektoren kann es zweckmäßig sein, im Gehäuseinnern Abstandshalter zwischen den beiden Glasplatten vorzusehen, die bei Evakuierung des Gehäuses den Außendruck aufnehmen. The invention relates to a plate-shaped solar collector, in which the housing containing the radiation absorber (3) is formed by two glass plates (1 and 2) and a metal spacer frame which is connected gas-tight to the edge of the glass plates, so that the housing is evacuated can. The spacer frame consists of a relatively torsion-resistant metal profile (7) and of flexible webs (8 and 9) made of an easily deformable metal arranged on the metal profile. These resilient webs are soldered to the metal profile on the one hand and to the glass plates metallized for this purpose in the edge area on the other hand. Square tube sections which are welded to one another in a vacuum-tight manner are preferably used as the metal profile, while a lead strip is expediently used for the webs. Depending on the size of the solar collectors, it may be advisable to provide spacers between the two glass plates in the interior of the housing ...
