Device for collecting and concentrating solar energy on a tube for conducting a heat carrier

A particularly straightforward mode of construction of the device is achieved by virtue of the fact that a curved sheet-metal strip as reflection element (5) is held in the desired shape by means of two thin end-plates (3', 4'). An edge area of the end-plates (3', 4') has the shape of a parabola. Tabs (28) extend outwards from this edge area and through slots (29) in the edge area of the sheet-metal strip (5). As a result of deformation of the tab parts projecting beyond the outer side of the sheet-metal strip (5), the said edge area of the sheet-metal strip (5) lies on the edge area of the end-plates (3', 4') so that the reflecting inner surface of the sheet-metal strip (5) forms at least approximately a cylindrical-parabolic mirror. A tube (2) for conducting a heat carrier extends through the end-plates (3', 4') and along the focal line of the said mirror. Secured on the outer side of the two end-plates (3', 4') is in each case a strut (3'', 4''), which struts project above the outer ...

Linearly concentrating solar collector and method for reflector tracking in such a solar collector

The basis for the function of a linearly concentrating solar collector lies, in simple terms, in the fact that reflectors reflect incident sunlight onto a receiver tube through which a heat-absorbing medium flows. Owing to the rotation of the Earth, the reflectors need to be adjusted regularly, however, in order to ensure that the sunlight hits the receiver tube. Known tracking methods use calculated positions of the sun for this purpose, which, in the case of structural deviations, for example as a result of expansion and material stress, results in inaccuracies and losses in efficiency. The invention is intended to improve the tracking of the reflectors in such a linearly concentrating solar collector. This is achieved by virtue of the fact that the radiation intensity in the region on both sides next to the receiver tube is measured and, by means of regulation, in the case of uneven emission on both sides of the receiver tube, the reflectors are tracked to such an extent that the radiation intensity on both sides of the receiver is the same and thus the maximum of the radiation intensity is on the receiver tube.
