[0002] With the increasingly scarce of non-renewable resources, and some non-renewable resources in people's life and industrial production caused various pollution problems, therefore all countries are using various policy or legal means to gradually increase the development and utilization of renewable energy and clean energy, and strive to improve its proportion in the whole energy use. In clean and renewable energy, solar energy as a kind of pollution-free, renewable energy, its development and utilization have been rapid development.

[0003] The existing battery piece is composed of multiple film layers, and the manufacturing process of each film and its position in the battery structure is usually different, so the manufacturing process is relatively complex. In the battery piece film manufacturing equipment, the tubular equipment and the plate type equipment are mainly used at present. For photovoltaic cell tubular equipment, there are mainly two kinds of gas inlet modes, one is flange gas inlet, and the other is air inlet pipe gas inlet.

[0004] The air inlet pipe gas inlet mode generally has a problem that the gas temperature does not match the furnace pipe temperature when the gas is inletted. Some special gases such as silane cannot be immediately decomposed when passing through the short air inlet pipe into the furnace pipe at normal temperature, which leads to uneven distribution of the gas flowing out from the pipe wall pressure relief hole, affecting the process effect.

[0008] Further, the air outlet hole is a circular hole.

[0009] Further, the air inlet pipe further comprises a paper clip section in the shape of a paper clip, one end of the paper clip section is connected with the zigzag section, and the other end is connected with the long straight pipe section.

[0010] Furthermore, the air intake pipe also includes a plug, which is disposed at the air outlet to block the air outlet.

[0011] Due to the application of the above technical solution, the beneficial effects of this application compared with the prior art are as follows:

[0012] This invention increases the total length of the inlet pipe by setting a bend between the inlet and outlet of the inlet pipe, thus extending the distance the gas is heated. On the other hand, the gas is buffered when it flows through the bend of the bend, reducing the gas flow speed and prolonging the time it takes to reach the furnace tube temperature, thereby improving the uniformity of gas distribution.
