Description
technical field [0001] The invention relates to an ultra-low temperature helium-free cooling system for high-speed optical fiber drawing production, and belongs to the technical field of optical fiber processing. Background technique [0002] The cooling process before high-speed optical fiber drawing production and coating will have an important impact on the optical fiber coating quality, optical fiber attenuation performance, and optical fiber drawing production speed. At present, optical fiber manufacturers use low-temperature cooling water to circulate in the cooling tank, and use helium gas as a medium to exchange the heat generated by the optical fiber production with the cooling tank to cool the optical fiber. Helium is a very rare gas and is expensive, and the cooling rate of low-temperature cooling water is slow, which directly affects the production speed of optical fiber drawing. Therefore, the existing low-temperature cooling system in the production process of...
