  • the support means In order to enable adjustment of the azimuth of the mirror to the changing position of the sun, it is attractive for the support means to comprise a substantially U-shaped frame and for the mirror carriers each to be connected to a ⁇ -shaped frame forming part of the support means for rotation about the same azimuth axis differing from the pivot axes.
  • the mirror can hereby be placed such that the axis of the parabolic cross-section of the mirror extends as parallel as possible to the direction of the solar radiation.
  • this axis preferably extends through or in the vicinity of the centre of gravity of the mirror.
  • the device preferably comprises azimuth drive means for causing rotation of the mirror about the azimuth axis, and azimuth control means for controlling the azimuth drive means so that in the operative position the axis of the parabolic cross-section of the mirror always extends as parallel as possible to the direction of the solar radiation. Adjustment of the azimuth of the mirror can hereby take place automatically. It is otherwise pointed out that the output of the solar collector greatly depends on the azimuth; only small variations result in a greatly reduced output.

  • the light sensor comprises a plate to be directed with its main surface toward the sun and two luminous flux meters disposed on either side thereof, and the azimuth control means are also adapted to adjust the azimuth of the mirror when the luminous flux of the luminous flux meters differs.
  • This same embodiment provides a method wherein the mirror is rotated about an azimuth axis for the purpose of making as small as possible the shade on a surface from a body to be directed toward the sun.
  • the output of a solar collector depends not only on the azimuth of the solar collector but also, albeit to a lesser extent, on the elevation.
  • a further embodiment provides the measure that the U-shaped frame is mounted on a carriage forming part of the support means for rotation about an elevation axis extending transversely of the longitudinal direction of the U-shaped frame, and that the device comprises elevation drive means for causing rotation of the frame about the elevation axis.
  • the device comprises an elevation control member for controlling the elevation drive means and that, depending on the geographical position and the date, the longitudinal direction of the mirror extends in the operative position as perpendicularly as possible to the incident solar radiation.
  • the carriage In order to improve the transportability of the device and to enable rotation of the longitudinal direction of the mirror as parallel as possible to the projection of the solar radiation on the earth's surface, it is recommended that the carriage is placed on a ground surface for rotation about a vertical axis.

  • a preferred embodiment provides a secondary mirror which is adapted to direct onto the absorption tube solar radiation reflected by said first mirror but not directed toward the absorption tube.
  • the absorption tube preferably has a cross-sectional form such that its effective absorbing outer surface is large compared to the inner cross-sectional throughflow surface in relation to the flow rate and the specific heat of the applied heat transport medium.
  • the heat-receiving surface of the absorption tube is on the one hand hereby increased, but the thus captured heat is on the other hand concentrated in a smaller quantity of heat transport medium, so that it is heated to a higher temperature, this resulting in thermodynamic advantages .

  • the form-retention of the construction is further improved when the foam is received in a casing of stable form, for instance of a hard polyurethane such as Polymed®.
  • the applying of reflective layers in the prior art usually takes place on flat carriers. Particularly in the case of curved carriers according to the invention it is attractive for the reflective layer to be applied by vapour-deposition, sputtering or other suitable process.
  • the carrier Prior to applying of the reflective layer the carrier must be brought into the desired form. This can take place in attractive manner when the surface to which the reflective layer is applied is modelled by cutting with a tensioned wire, followed by an ageing, for instance for about six weeks, for the purpose of obtaining the desired stability of form. It is attractive for thermodynamic reasons that the radiation absorption tube is formed by a heat pipe. The heat obtained from the sun is hereby used not only to heat the heat transport medium, but also to cause a phase change, in particular evaporation, so that a larger amount of thermal energy can be absorbed.
