Because solar energy is relatively diffuse, it must be managed to be concentrated, so collectors are a critical part of various solar devices. Among them, a solar water heater for generating hot water is a solar collector which is relatively commonly used.

The existing heat collecting tube of the solar water heater generally adopts a full glass vacuum tube, the shape of the heat collecting tube is a cylindrical tube with an opening at one end, a glass inner tube and a glass outer tube are made of glass, the glass inner tube and the glass outer tube basically keep concentric circles, a vacuum state is formed between the glass inner tube and the glass outer tube, the glass inner tube and the glass outer tube are sealed through a sintering process after being vacuumized, and the wall of the glass inner tube is brushed with black solar energy to absorb heat. 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.
