Solar energy refers to the heat radiation energy of the sun, the main expression is solar rays which are commonly called as solar rays and are generally used for power generation and heat storage; the solar photovoltaic heat storage device is generally a solar water heater and comprises a vacuum tube, a water storage tank, a bracket and other related parts; the solar vacuum tube is a core component of the device, and the performance and the service life of the vacuum tube directly influence the service life of the solar water heater.

The glass vacuum solar heat collecting tube is a tube fitting for heating water by utilizing solar energy, and is formed from inner and outer two concentric circular glass tubes, and the selective absorption wax with high absorptivity and low emissivity is deposited on the external surface of inner tube to form heat-absorbing body, and between the internal tube and external tube an interlayer is pumped into high vacuum, and its form is like a slender thermos flask liner. The working principle is that the solar energy can irradiate the heat absorber on the outer surface of the inner tube through the outer glass and is converted into heat energy, then the heat transfer fluid in the inner glass tube is heated, and the heat loss to the surrounding environment is effectively reduced due to the vacuumizing between the interlayers, so that the heat collection efficiency is improved. Because the all-glass vacuum solar heat collecting tube is made of glass materials, the whole structure is fragile, the all-glass vacuum solar heat collecting tube is usually arranged on a roof to prevent the tube from being damaged by foreign objects in the period of time, and the light collection of the all-glass vacuum solar heat collecting tube is ensured; however, when snowing or hail occurs, the water tank and the heat collecting pipe of the solar water heater are easily damaged, and the service life of the whole solar water heater is influenced.
