Description

Technical Field

[0001] The utility model relates to the technical field of solar water heaters, in particular to an energy-saving multi-temperature section temperature-controlled solar water heater. Background Art

[0002] Solar water heaters are mainly composed of heat collecting tubes, water tanks, base frames and other related parts and components. The conversion of solar energy into heat energy mainly depends on heat collecting tubes. The heat collecting tubes mainly include vacuum tubes composed of coaxially arranged inner and outer tubes - there is a vacuum annular cavity between the inner and outer tubes, and a heat-absorbing coating is attached to the wall of the inner tube.

[0003] The reflector is used to reflect the sunlight between the heat collecting tubes and between the inner tube and the outer tube to the heat collecting tube, especially the inner tube of the heat collecting tube. However, the position of the reflector, the base frame and the heat collecting tube is relatively fixed, and the incident angle of sunlight changes all the time during the day. No matter how the shape of the reflector is improved, the reflector with a fixed position and angle cannot reflect more sunlight between the heat collecting tubes to the heat collecting tube at every time period. This reflector can only fully exert its effectiveness at a specific time of the day, and the light reflected to the heat collecting tube at other times is very little. Utility Model Content
