  • a solar collector or solar collector, is a component of a solar thermal installation.
  • the solar collector is a type of solar panel in charge of capturing solar radiation and transforming it into thermal energy, which is known as renewable energy.
  • the type of solar collector will be chosen depending on the use and the efficiency that is required. If the requirement is to heat a pool at a temperature of 25-28 degrees Celsius, in spring, a simple solar collector is necessary, since the ambient temperature will be within the required range or possibly higher. In another case, if it is intended to heat a fluid to 200°C, a concentrating solar collector will be necessary to concentrate the solar radiation and have it transferred to a small volume of fluid.

  • Solar panels using this system take advantage of the phase change from vapor to liquid within each tube, to deliver energy to a second transport liquid circuit.
  • the elements are closed tubes that contain the liquid that, when heated by the sun, boils and turns into steam. These tubes are usually made of copper.
  • the generated steam rises to the upper part where there is a wider head (condensation zone).
  • the outer part of the condensation zone is in contact with the transporting liquid. Because the transformer liquid is at a lower temperature than the steam in the tube, it captures heat thanks to a thermodynamic convection process and causes the steam to condense. The condensed liquid falls back into the lower part of the tube to start the cycle again.
  • the liquid in the tube can be water that will have a low boiling point to work even with the insolation of infrared rays in case of cloud.
  • the heat pipe can be wrapped with insulating materials to minimize irradiation losses.
  • the heat pipe is closed inside another glass tube between which a vacuum is made to insulate.
  • a concentration solar collector is one that uses a technique of concentration of solar radiation to obtain high temperatures. This technique is used in high and very high temperature solar installations.

Abstract

La présente invention décrit un collecteur solaire polymère qui comprend un tuyau d'absorption et qui présente installée sur sa surface extérieure et de manière longitudinale une pluralité de plaques linéaires, ainsi qu'une pluralité de plaques circulaires qui sont parallèles aux plaques linéaires. Le collecteur comprend également sur sa surface extérieure une pluralité de plaques obliques en forme de "x", qui sont situées dans les espaces formés entre les plaques linéaires et les plaques circulaires. Ces plaques sont en polymère, ce qui permet une plus grande absorption de l'énergie thermique, ce qui par conséquent augmente la température de manière plus efficace du liquide qui se trouve dans le tuyau d'absorption. Le collecteur solaire polymère présente une plus grande résistance mécanique grâce à la pluralité de plaques qui le composent, de sorte qu'il est possible de le faire fonctionner à des pressions de travail basses et élevées, ce qui le rend également plus résistant aux chocs. Une autre caractéristique de la présente invention, est qu'elle comprend au niveau des extrémités, des mécanismes de couplage qui permettent de relier en série deux ou plusieurs collecteurs avec un moyen de fixation, ce qui permet de chauffer un volume de liquide supérieur.
