Water is injected into the glass inner tube, and sunlight irradiates on the solar heat absorption layer so as to heat the water in the inner tube. However, the characteristic of glass articles being prone to chipping for various reasons also places a hidden danger in the use of such collectors. For example, when the vacuum tube is in operation, the tube orifice is impacted by the temperature of cold water suddenly coming in at a high temperature, the cold and hot water at different positions are uneven, the internal stress suddenly increases to cause the vacuum tube to generate cracks or burst and other tube explosion phenomena, so that a large amount of water overflows, the waste of water resources is caused, the normal working operation of the solar water heater is seriously influenced, and the use and maintenance cost is increased.
