Description

Technical Field

[0001] The present invention relates to the technical field of transparent cover plates, and particularly relates to a tempered glass transparent cover plate for a solar collector. Background Art

[0002] Tempered glass belongs to safety glass. Tempered glass is actually a kind of prestressed glass. To improve the strength of the glass, chemical or physical methods are usually used to form compressive stress on the glass surface. When the glass bears external force, the surface stress is first offset, thereby improving the bearing capacity and enhancing the wind resistance, cold resistance, impact resistance, etc. of the glass itself. Note the difference from fiberglass. The basic structure of the glass cover plate is a glass fiber-reinforced transparent resin plate, and its advantages mainly include light weight, easy processing and forming, small heat conductivity, strong impact resistance, etc. Tempered glass is obtained by first cutting ordinary annealed glass into required sizes, then heating it to about 700 degrees close to the softening point, and then rapidly and evenly cooling it (usually, 5-6MM glass is heated at 700 degrees high temperature for about 240 seconds and cooled for about 150 seconds. 8-10MM glass is heated at 700 degrees high temperature for about 500 seconds and cooled for about 300 seconds. In short, according to the different thicknesses of the glass, the heating and cooling times are selected differently). After tempering, uniform compressive stress is formed on the glass surface, while tensile stress is formed inside, so that the bending and impact resistance of the glass are improved, and its strength is more than four times that of ordinary annealed glass. The tempered glass that has been tempered cannot be cut, ground or damaged any more, otherwise it will "fall to pieces" due to the destruction of the uniform compressive stress balance. A collector, also called a heat collection plate, is the name of the outdoor heat collection component of a solar water heater in the solar energy industry. A solar collector with good performance is one of the key devices of a solar air conditioner. The mature solar collectors mainly include: flat plate collectors, all-glass evacuated tube collectors and heat pipe evacuated tube collectors. Flat plate collectors are widely used all over the world for their simplicity, low cost and easy installation. Its main function is to collect the heat energy in sunlight, and through a connecting pipeline, transfer it to the water tank to heat the cold water in the water tank.
