Definitions

  • This invention relates to a solar heat collection apparatus, and more particularly to a trough type solar heat collection apparatus.
  • a known trough type solar heat collection apparatus As disclosed in PTL 1, sunlight is collected in a heat collecting tube using heat collecting means having a parabolic surface, and as a result, a heating medium flowing through the heat collecting tube is heated.
  • the heat collecting tube used in this solar heat collection apparatus has a duplex tube structure formed of a glass outer tube and a metal inner tube so that sunlight is efficiently converted into heat, enabling a reduction in heat loss. Further, an enclosed space set in a vacuum condition is provided between the outer tube and the inner tube.
  • an exhaust hole is provided in the outer tube, and after air has been discharged through the exhaust hole, the glass tube is heated and sealed.
  • a sealing mark remains in the form of a projecting bump in the location where the exhaust hole was sealed.
  • the projecting part of the sealing mark may be struck while installing the solar heat collection apparatus or handling the heat collecting tube during maintenance, and as a result, the outer tube may be damaged.
  • the heat collecting tube is packed into a box made of a hard material, such as a wooden box, the projecting bump part may strike a wall of the box or an adjacent heat collecting tube such that the outer tube is damaged. Therefore, when the heat collecting tube is packed into a box or the like, packing must be performed while taking into consideration orientations and positions of individual heat collecting tubes, making the packing operation laborious.
  • PTL 2 describes attaching an exhaust tip tube to a metal support tube that is provided between the inner tube and the outer tube in order to support the inner tube relative to the outer tube, discharging air by connecting a vacuum pump to the exhaust tip tube, and then sealing the exhaust tip tube.

  • a plurality of heat collecting tubes are connected in succession at respective end portions thereof so as to extend in a lengthwise direction. Therefore, if the exhaust tip tube projects when the end portions of respective heat collecting tubes are connected to each other, a space for the exhaust tip tube must be secured in the lengthwise direction, leading to a corresponding reduction in an effective length by which the end portions can be connected to each other, and as a result, the heat collecting tubes cannot be connected easily.
  • This invention has been designed to solve the problems described above, and an object thereof is to provide a solar heat collection apparatus with which damage to an outer tube can be prevented and heat collecting tubes can be easily connected to each other in a lengthwise direction.
