It can be said that the mainstream of global energy in the future will be solar energy, and solar energy utilization technology is being paid more and more attention. Solar collectors are the most important components in solar thermal utilization, and their performance plays a decisive role in the success or failure of the entire system. According to the basic characteristic of whether it is concentrating or not, it can be divided into two categories: non-concentrating and concentrating.

[0003] A solar collector with good performance is one of the key technical equipment for solar air conditioners. Mature solar collectors mainly include: flat plate collectors, all-glass evacuated tube collectors, and heat pipe evacuated tube collectors.

[0004] When the glass tube in the heat pipe evacuated tube collector is produced, it is necessary to carry out melting and sealing treatment on the glass tube so that the glass tube can form a vacuum state, which is convenient for heat collection. When the glass tube is melted and sealed, it is necessary to use a clamping mechanism to clamp and fix the glass tube to maintain the stability of the glass tube, which is convenient for the glass tube to rotate and be melted and sealed, and it is necessary to protect the glass tube. However, when the existing technical equipment clamps the glass tube, it is easy to cause damage to the glass tube, and it is not convenient to adjust the size of the clamping mechanism, the adaptability is not high, and the stable clamping and fixing cannot be realized.
