Description

Technical Field

[0001] The utility model relates to the technical field of solar water heaters, in particular to a solar water heater with an overheating protection function. Background Art

[0002] A solar water heater is a device that uses solar energy to convert sunlight into heat to heat water. It consists of a solar collector, a water storage and circulation system. The solar collector absorbs the heat from the sun and transfers it to the water, heating it up. The water storage and circulation system is used to store and distribute the heated water, ensuring the stability of the hot water supply.

[0003] However, when the water heater is running and the water temperature in the insulation barrel reaches the boiling point, if the solar collector continues to be exposed to sunlight, the water in the insulation barrel will begin to generate water vapor. Since the insulation barrel is sealed, the water vapor cannot leak out and can only accumulate in the insulation barrel, gradually increasing the pressure, which may cause damage to the insulation barrel or the solar collector tube, and ultimately make the solar water heater unable to work properly; in view of this, we propose a solar water heater with overheating protection function.
