Definitions

  • the present invention broadly relates to a reflector and to a receiver for a solar energy collection system.
  • the present invention relates particularly, though not exclusively, to a reflector and to a receiver for reflecting and absorbing solar energy from an array of solar energy collectors.
  • a solar energy collection system typically includes an array of solar energy collectors, such as an array of reflectors, which collect the sunlight and direct the collected sunlight to a receiver positioned over the array.
  • the collected sunlight is focussed onto an absorber in the receiver and heats the absorber locally to a temperature of approximately 350 0 C.
  • the conversion efficiency of the energy from the collected sunlight to electricity is better at higher temperatures such as temperatures of 500° to 600°.
  • high temperatures cause a number of problems.
  • the collected sunlight needs to be concentrated onto a very small area of the absorber.
  • typical receivers comprise an absorbing body positioned in an evacuated glass housing and typically cannot withstand temperatures higher than approximately 350 0 C. Consequently, there is a need for an alternative technological solution.
  • the present invention provides in a first aspect a reflector for a solar energy collection system, the reflector being arranged for diverting radiation received from solar energy collectors, the solar energy collectors being arranged for focusing the collected light to an elongate focal region and the reflector comprising at least one elongate reflecting surface portion arranged to divert radiation received from a solar energy collectors.
  • the reflector may in use be positioned at a level above the solar energy collectors, which may themselves be primary reflectors, and arranged to divert the radiation in a downward direction to a level below that of the reflector so that the elongate focal region is in use at a level below that of the reflector such as a position on or near a ground plane.
  • This has the significant advantage that relatively high angles of incidence of the radiation may be achieved without the need to position a receiver, which may comprise a further reflector, high above the solar energy collectors.
  • the elongate reflecting surface may be substantially planar, but typically has a concave or convex cross- sectional shape in a plane perpendicular to the direction of elongation.
  • the elongate reflecting surface portion may have a cross-sectional shape that varies in the direction along the elongation.
  • the reflector may also have a first region having a concave cross-sectional shape and a second region having a convex cross-sectional shape.
  • the reflector has a cross-sectional shape that is substantially constant in the direction of the elongation of the reflecting surface portion.
  • the cross-sectional shape of the elongate reflecting surface portion is concave.
  • the concave reflecting surface portion may comprise a plurality of surface portions or segments which may be joined.
  • the reflecting surface portion may comprise a plurality of substantially planar reflecting portions which are arranged in a concave shape.
  • the reflecting surface may comprise a concave layer which may be integrally formed.
  • the present invention provides in a second aspect a receiver for a solar energy collection system, the receiver comprising: a housing having an interior space which can be evacuated and a light-transmissive window for transmission of light through the window into the interior space, an absorbing body positioned in the interior space of the housing for absorbing the light, wherein the receiver is arranged for evacuation of the interior space using a vacuum pump during use of the receiver.
  • the housing of the receiver may be arranged for connection to the vacuum pump.
  • the vacuum pump may be an external pump, but may also be an internal pump that may be positioned in the housing (for example a getter pump) .
  • the receiver has a number of advantages. Because the interior space can be evacuated by the vacuum pump during use of the receiver, heat conduction from the absorber body to the window, which may be a glass window, is reduced and consequently the window has in use typically a temperature that is much lower than that of the absorber body. Consequently, the receiver is suitable for higher temperatures than conventional receivers.
  • the housing typically comprises a material that is thermally insulating and is arranged to reduce heat conduction from the absorbing body to the window which further increases suitability for high temperatures.
  • the housing may comprise an inner portion which may be metallic and an outer portion which may comprise the thermally insulating material.
  • supports such as pilar-type supports, which support the absorber body in the housing may comprise the thermally insulating material.
  • the thermally insulating material typically is a ceramics material.
  • the absorber body may have any suitable shape but typically is shaped so that at least a portion of the light that is reflected by a surface portion of the absorber body is reflected to another surface portion of the absorber body. For example, if the light is reflected three times and each time 80% of the light is absorbed, only less than 1% of the light may escape.
  • the absorber body has a substantially U-shaped or V-shaped cross-sectional shape.
  • the substantially U- or V- shaped absorber body has the advantage of having a larger surface to volume ratio than a conventional absorber body which typically is a pipe having a round cross-sectional shape. Consequently, the substantially U- or V-shape of the absorber body increases the absorption efficiency.
  • the receiver may be arranged for heating of any suitable material such as a gas or a liquid.
  • the absorber body comprises a conduit for a fluid that is in use directed through the absorber body.
  • the conduit may also have a substantially V- or U-shaped cross-sectional shape. If the fluid is a liquid that is in use directed through the absorber body and heated by the absorber body, this shape of the conduit has a particular advantage. Liquids may form bubbles when heated which would diffuse to areas near end portions of the legs of the substantially V- or U-cross-sectional shape of the conduit. However, other regions of the conduit would be largely bubble free and can efficiently absorb heat.
  • the absorber body may comprise any suitable material but typically comprises an absorptive surface coating such as a highly absorptive "black body” type surface coating.
  • the absorber body may also have a solar selective coating such as a coating that absorbs sunlight but only emits a relatively small amount of infrared radiation.
  • the housing typically has an interior surface portion that is reflective so that solar light that is directed to the interior surface is reflected to the absorber body and heat loss is reduced.
  • the housing interior surface may comprise a metallic material that is reflective.
  • the receiver may be arranged for receiving radiation collected by a plurality of collectors which focus the collected light to an elongated focal region such as a linear focal region.
  • the absorber body typically is elongated so that the absorber body can receive the radiation associated with the elongated focal region.
  • the present invention provides in a third aspect a solar energy collection system comprising the reflector according to the second aspect of the present invention.
  • the reflector in use diverts radiation to the receiver, it is possible to avoid relatively small angles of incidence without the need to position the absorber at a very high level above the solar energy collectors. As relatively small angles of incidence can be avoided, loss of concentration due to broadening of the beam is reduced and it is possible to achieve higher absorber body temperatures.
  • the solar energy collection system typically comprises a receiver such as the receiver according to the first aspect of the invention.
  • the reflector typically is positioned at a level above the solar energy collectors and arranged to divert the radiation in a downward direction.
  • the receiver may be positioned on a ground plane.
  • An elongate focal region of the solar energy collection system typically is in use directed into the receiver of the solar energy collection system.
  • the solar energy collection system may not comprise a receiver but may be arranged for direct heating of a material such as a solid material.
  • the solar energy collection system may be arranged for heating of a solid fuel such as brown coal.
  • Australian brown coal has a relatively large concentration of moisture which is of disadvantage for combustion.
  • the solar energy collection system may be arranged for heating of the brown coal and thereby reducing moisture concentration in the brown coal.
  • the reflector may comprise two or more concave reflecting surface portions.
  • the reflector may comprise two concave reflecting surface portions arranged so that the reflector has a cross-section that comprises two concave portions.
  • the system typically is arranged so that the reflector is positioned over the receiver with collectors positioned on either side of the receiver and respective concave reflecting surface portions divert radiation received from solar energy collectors located at respective sides of the reflector.

  • the absorber body 14 has a U-shaped cross- sectional shape.
  • the absorber body 14 in this example is composed of a metallic material which has a "black body" coating to increase the absorption of received sunlight. Due to the likelihood for multiple reflections of the received sunlight by the absorber body 14 the absorption efficiency is increased.
