Solar glass vacuum heat collecting tube

Abstract

Solar energy glass aggregating heat pipe relates to the solar energy heat utilization technique, comprising two transparent glass caecal tubes which are of muff coupling synthetic, inner glass caecal tube wherein mental pipe having solar energy heat absorption film on the surface is set and outer glass caecal tube are of fusing at their open end, vacuum cavity is set between the two glass caecal tubes and condense reflection device whose curve-racket - shaped section is set between the them. The invention is easy to be adopted to practical production and processing meanwhile, its bearing performance is increased by using high strength character of metal, most importantly, by condense reflection device not only supplies the possibility of using light energy fully but also increases energy flux density of the glass heat pipe ectosexine by the light assembled, making output temperature of aggregating heat pipe aggregating heat pipe higher than that of its and supplying wider space for using solar energy.

Description

technical field [0001] The invention relates to solar heat utilization technology. Background technique [0002] At present, the key component commonly used in the field of solar water heaters is the all-glass vacuum heat collecting tube, because the heat collecting tube is connected by two glass blind tubes inside and outside at the common opening end, and a vacuum chamber is formed between the two tubes. The solar heat-absorbing film is set on the outer surface of the inner glass blind pipe. When in use, the heat transfer medium in the inner glass blind pipe—water is not conducive to improving the heat conversion rate, cannot bear pressure, and cannot output higher temperature. In addition, There is a large amount of water in the tube, which is easy to cause heat loss at night, and the effective hot water utilization rate is low, which affects the further expansion of the field of solar thermal utilization. Some people in the industry are studying the use of metal tubes t...

[0002] At present, the key component commonly used in the field of solar water heaters is the all-glass vacuum heat collecting tube, because the heat collecting tube is connected by two glass blind tubes inside and outside at the common opening end, and a vacuum chamber is formed between the two tubes. The solar heat-absorbing film is set on the outer surface of the inner glass blind pipe. When in use, the heat transfer medium in the inner glass blind pipe—water is not conducive to improving the heat conversion rate, cannot bear pressure, and cannot output higher temperature. In addition, There is a large amount of water in the tube, which is easy to cause heat loss at night, and the effective hot water utilization rate is low, which affects the further expansion of the field of solar thermal utilization

Some people in the industry are studying the use of metal tubes to replace glass inner blind tubes, but due to the difficulty in sealing the connection between metal and glass, it is not easy to introduce them to the market
