Abstract

Disclosed is a cooling apparatus used in a high-speed cooling of an optical fiber. The cooling apparatus includes: a cooling body extending along the longitudinal direction of the drawn optical fiber, wherein the cooling body consists of a left cooling body part and a right cooling body part, and wherein the cooling body is provided with a sealing cap so that a cooling gas is supplied into the cooling body through the sealing cap; and, at least one turbulence generator mounted within the cooling body to surround the drawn optical fiber, wherein the turbulence generator activates the molecular flow of the cooling gas supplied into the cooling body.

Description

technical field [0001] The invention relates to an optical fiber drawing device for drawing a single bundle of optical fibers from an optical fiber preform rod, in particular to a cooling device for high-speed optical fiber drawing. Background technique [0002] The process of manufacturing an optical fiber is generally divided into the steps of preparing an optical fiber preform and drawing the optical fiber to extract a bundle of optical fibers from the prepared preform. Numerous research attempts have focused on the preparation of large diameter optical fiber preforms, especially in the preparation of optical fiber preforms for the extraction of large quantities of optical fiber bundles. For example, an over-jacket tube method, a rod-in-tube method, and the like have been employed in manufacturing large-diameter optical fiber preforms. figure 1 A conventional cooling device employed in the process of drawing an optical fiber preform is shown. Such as figure 1 As shown,...
