Description

Technical Field

[0001] The utility model relates to the technical field of solar energy heat collection, in particular to a non-powered mechanical antifreeze type heat collection water circulation system. Background Art

[0002] With global warming, the concepts of low carbon and environmental protection have gradually attracted people's attention, and the use of pollution-free new energy is a specific manifestation of low carbon and environmental protection. Solar energy is a clean and renewable energy, and it is also a new energy that people use more frequently. Equipment such as solar water heaters are devices that convert solar energy into thermal energy.

[0003] Existing solar water heaters are generally composed of collector tubes, water storage tanks, brackets and other related accessories. Their working principle is mainly that the collector absorbs solar heat energy and transfers it to water stored in the water tank, which is then transported to the user's desired location through a pipe connected to the water tank.

[0004] At present, due to the limited capacity of the water tank of the solar water heater, when the solar collector absorbs a lot of solar energy but the user does not need to use water, the heat energy will be lost and wasted, resulting in energy waste.

[0005] Depending on the lighting time and intensity, the real-time heat collection temperature of the solar water heater will change, causing the water temperature in the water tank to change all the time. When using water, hot water at a certain temperature is required. The hot water temperature in the water tank cannot always meet the water demand. Therefore, it is necessary to design a non-powered mechanical anti-freeze heat collection water circulation system that can circulate and regulate the water temperature. Utility Model Content

[0042] A check valve 17 is provided on the circulating water inlet pipe 2 at one side of the input end of the circulating pump 5 to prevent the water in the circulating water inlet pipe 2 from flowing back into the non-pressurized hot water storage tank 4 .

[0043] The input end of the circulating water return pipe 3 is provided with a temperature probe 13 and an exhaust valve 14. The temperature probe 13 is used to monitor the water temperature of the hot water flowing out from the output end of the non-powered antifreeze type large flat plate collector module 1.
