A New Type of Solar Concentrating Heat Collector

technical field

The utility model relates to a solar concentrating heat collector for generating heat by using sunlight energy, in particular to a novel solar concentrating heat collector.

Background technique

At present, with the improvement of people's living standards, the use of hot water or heating medium in daily life is constantly increasing; in order to protect the natural environment and natural resources, solar water heaters have appeared, and these water heaters use vacuum insulation tube technology. The temperature of water or other media is raised, but the light-receiving area of the vacuum insulation tube is relatively small, and the solar energy cannot be fully utilized, so the temperature of the heated hot water or other media is not very high, which reduces the efficiency of solar energy; and If the cut-off area of the solar concentrator can be increased to a greater extent, and the light intensity can be increased several times to improve the use effect of solar energy, it will bring greater convenience to people's life, but such a solar concentrator has not yet been developed. Appear.
