Description

Technical Field

[0001] The utility model relates to the technical field of solar water heaters, in particular to a high-efficiency heat-collecting solar water heater. Background Art

[0002] Solar water heaters are heating devices that convert solar energy into thermal energy, heating water from low temperature to high temperature to meet people's hot water needs in life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structural forms. Vacuum tube solar water heaters are the main ones. Vacuum tube household solar water heaters are composed of collector tubes, water storage tanks, brackets and other related parts and components. The conversion of solar energy into thermal energy mainly relies on vacuum collector tubes. Vacuum collector tubes use the principle that hot water floats and cold water sinks to make water microcirculate and obtain the required hot water: When the vacuum collector tube heats the cold water inside it through light, since the vacuum tube is installed at intervals, sunlight cannot shine on the back of the vacuum tube, making the vacuum tube unable to heat the cold water efficiently. The traditional reflector is directly laid on the back of the vacuum tube. The traditional reflector is fixed and cannot be adjusted in angle. Although the reflector can reflect the sunlight passing through the vacuum tubes, it also blocks the wind passing through the vacuum tubes to a certain extent, resulting in increased wind resistance and easy detachment of the reflector in strong winds.
