Definitions

  • the present invention relates to a solar boiler or warm water container in a specific form which can be heated by solar energy and which is surrounded by a vacuum in order to reduce the eillere in the container when heated by the sun and when stocks are kept.
  • a container, Pat. No. FR PS 2459948, of the above type shows, for example, the heat-absorbing surface in the form of a pyramid, which is stripped to the outside by a vacuum, absorbs the heat of the sun shining through and releases it to the internal medium
  • the supply and discharge lines must be filled and emptied.
  • the structure shows the straight surfaces of the container with many sealing points and possible sources of error to maintain a vacuum permanently.
  • This shape is not suitable for higher pressures in the container, if it were to be made pressure-resistant, the container would have very thick walls, which is not advantageous for an economical construction.
  • no account is taken of the fact that the pyramid-shaped medium container has very hot medium at the tip and the lower zones remain cold for a long time, with expensive bottom insulation of the container being necessary in order to avoid heat losses downwards.
  • the object of the present invention is to develop a novel structure of the solar boiler while avoiding the disadvantages mentioned, using simple means and with a view to a still inexpensive production possibility and great operational reliability.
  • the invention consists in that the "media container the most pressure-resistant mold has r is formed in the substantial kugelfo 'ig, wherein the kugä ge form for good uniform introduction of the
  • Solar heat in the medium serves, regardless of the position of the sun to the container, with the minimum radiation area of the container to the storage amount of the medium held in storage, that the medium container in a substantially spherical
  • the container has only a small zonal connection to the medium container, which is used for the feed and discharge lines and is designed in half-shells, that the half-shells are made of different materials and only one that is transparent to the sun, that the approximately symmetrical half-shells are connected by a sealing element, thermal expansion occurring at the contact point of the hemisphere being transferred non-positively and compensated in order to protect the sealing element so that an almost loo% between the two spherical containers
  • Vacuum works, whereby the spherical construction saves weight and has the size that it is easy to carry when empty, that several solar boilers can be divided together in modules to increase the storage capacity of a system, that the * surface of the media container is structured on the outside and is smooth on the inside, on the one hand to quickly absorb the solar energy and to release it quickly on the inside, whereby the medium starts to move and collects the heat from the smooth inside.
  • the selarboiler has at least one cold and hot water connection, the hot water pipe being displaceable in order to remove media from different zones.
  • the hot water pipe is mounted at a distance from the top of the media container in order to obtain a larger air cushion to be compressed for the thermal expansion of the medium, that the main safety valve is attached to the cold water screw connection, that the hot water pipe in the medium container has thermal insulation , whereby the medium does not cool down during the period of a next medium removal that the solar boiler can be used as a heat source for absorber heat pump systems in modules, the spherical media container being well resistant to the prevailing high pressure such that the vacuum is above a shut-off valve attached to the lower hemisphere is built up and can be built up at any time so that repairs to the solar boiler can be carried out quickly and easily,
  • FIG. 1 An exemplary embodiment is shown in the drawing.
  • the drawing shows a cross section through the solar boiler.
  • the cold and hot water connections 3 which have been carried out are attached to the connecting zone 6.
  • the frame 4 holds the solar boiler.

Abstract

Chauffe-eau solaire se composant d'un récipient de milieu essentiellement sphérique (2) transférant rapidement la chaleur incidente au milieu, et d'un récipient extérieur transparent formé de deux demi-coupes essentiellement sphériques (1), comportant dans la liaison en forme de zone (6) le passage des conduites de milieu (3), entre les deux récipients sphériques (1) et (2), de construction trés légère et économique quant au matériau, se trouvant un vide créé de l'ordre de presque 100% afin de garantir l'isolation optimale du récipient du milieu (2). Les demi-coupes sont reliées rigidement au moyen d'éléments d'étanchéité (5) et peuvent bien compenser des dilatations thermiques.
