Definitions

  • Embodiments of the present invention are generally related to a formed reflector support arm used in parabolic trough solar concentrators.
  • Parabolic trough solar concentrators utilize a fluid-filled receiver tube that is positioned above sun-tracking reflectors that focus solar energy onto the receiver tube.
  • the size of the focusing reflectors and associated installations has increased. More specifically, one way to increase solar energy production is to increase the size of the reflectors, receiving tubes, etc., which necessarily increases the size and weight of the associated support structure.
  • reflector support structure is comprised of a truss made of a number of welded components. Some larger structures are comprised of stamped or otherwise formed support members. As one of skill in the art will appreciate the larger and more complex the support structure becomes, the greater the associated fabrication costs. Accordingly, it is desirable to provide reflector support assemblies that can be produced inexpensively and that can accurately maintain a desired position of relatively large reflectors under various conditions.
  • truss support structures are used as they provide sufficient strength and stiffness, while maintaining an acceptable weight.
  • Typical truss support systems are comprised of individual support members that are formed from multiple pieces of material, such as steel or aluminum that are welded or riveted together. Brackets for connecting the reflectors, i.e., a series of mirrors or other reflecting members to the support arms, and for connecting the support arms to a central support structure, are then added to the truss.
  • truss designs can be used to support reflectors of varying sizes, such designs can suffer from a number of disadvantages.
  • a primary disadvantage is that the truss manufacturing process is relatively labor intensive and complex. Also, such processes often result in a relatively large amount of wasted material.
  • Another disadvantage is that the manufacturing process is typically imprecise. More specifically, many solar collecting assemblies are constructed by first laying down the reflectors on an assembly support with the reflective side down. Next, plurality of truss members are interconnected to the back side of the reflectors, often with brackets or ceramic pads positioned between the reflectors and the truss elements. Then the assembly is lifted and rotated to orient the mirrors facing up. The pads that attach the reflectors to the truss structure can then be modified to ensure that the maximum amount of light gathered by the reflectors is focused on receiving tube.
  • a solar concentrator reflector support assembly that utilizes multiple support members, some of which are formed of a shape that facilitates manufacture of a concentrator reflector assembly.
  • the contemplated support members that are attached to the reflector elements, or mirrors are formed or shaped support members.
  • the reflector support members generally include a support surface or interface that may possess a shape that corresponds with the shape of the reflective element. Accordingly, at least a portion of the support surface is curved.
  • the support members also include a backing surface that is spaced from the support surface. An intermediate member extends between at least a portion of the support surface and a portion of the backing surface.
  • Each support member can also include at least a first pad associated with the mirror support surface, and an interconnection feature for attaching the support member to other members of the structure.
  • a reflector support assembly in accordance with embodiments of the present invention can also include an interconnection member that has a first end that is fixed to the interconnection feature of a first support member. A second end of the interconnection member is fixed to either a central support structure or to a second support member. Similar to the mirror support members, the interconnection members can be formed from a single piece of material. Methods in accordance with embodiments of the present invention include forming support members that are not linear along at least a first surface from an integral piece of material. The first surface, or reflector support surface, can include one or more reflector interface features.
  • the reflective members can directly interconnect to the curved surface.
  • the support surface can be formed with the accuracy required to focus the mirrors or reflectors on the receiver tube or other target.
  • mirror pads may be associated with the first surface.
  • An interconnection feature may be formed on a second surface of the support member.
  • the interface features, the mirror pads, and/or the interconnection features are formed simultaneously with the formation of the associated support member.
  • the interface features, the mirror pads, and/or interconnection features may be integral to the associated mirror support member.
  • Forming the support members can include stamping the members from sheet stock, roll-forming, bending, stretch forming, or by other known mechanical or hydraulic bending and forming processes.
  • a mirror support assembly can include interconnecting first and second support members via the interconnecting member that, like the mirror support members themselves, is curved along at least first, second, and third surfaces.
  • the interconnecting member can include a mirror pad and an interconnection feature.
  • a solar concentrator comprising: a plurality of spaced support assemblies, each comprising a first formed outer section having first end and a second end, and a curved reflective element support surface; a second formed outer section having first end and a second end, and a curved reflective element support surface; a first formed inner section having first end and a second end, and a curved reflective element support surface; a second formed inner section having a first end and a second end, and a curved reflective element support surface; wherein the second end of the first formed outer section is associated with the second end of the second formed outer section; wherein the first end of the first formed inner section is interconnected to the first formed outer section at a point between the first end and the second formed end of the first formed outer section; wherein the first end of the second formed inner section is interconnected to the second formed outer section at a point between the first end and the second end of the second formed second outer section; wherein the second formed end of the first formed inner section is associated with
