Abstract

The invention discloses a device for cooling optical fiber wires online by using hydrogen. The device comprises a cooling tube (2), a cooling air pipeline (10), a gas pipeline (8), a pump, a hydrogen recycling and purifying device (5), a hydrogen supply device (6) and a gas flow control device (7), wherein the cooling air pipeline (10) is coaxially arranged with the cooling tube (2); the gas pipeline (8) is communicated with the cooling air pipeline (10); the pump, the hydrogen recycling and purifying device (5), the hydrogen supply device (6) and the gas flow control device (7) are arranged on the gas pipeline (8) in sequence; sealing devices (4) are arranged between one end of the cooling air pipeline (10) and the cooling tube (2) and between the other end of the cooling air pipeline (10) and the cooling tube (2). The specific heat capacity of the hydrogen employed by the device is greater than that of nitrogen, so that the cooling effect is relatively good; in addition, the hydrogen is an ordinary gas which is very convenient to supply and is cheap, so that the cost of production companies is lowered.

Description

technical field [0001] The invention relates to a cooling device, in particular to an online cooling device for optical fiber drawing using hydrogen. Background technique [0002] With the continuous development of optical fiber technology, the drawing speed of optical fiber is getting faster and faster. The temperature of the optical fiber when it comes out of the drawing furnace reaches 1500 ° C. It generally does not exceed 1 second from the drawing furnace to the coating system. It is also as high as several hundred degrees, and the optical fiber cannot be effectively coated and protected. At the same time, the stress of the optical fiber during the cooling process cannot be released, and direct coating will seriously affect the performance of the optical fiber. In order to ensure a good coating effect and excellent performance of the optical fiber, it is necessary to perform forced cooling on the optical fiber. Usually, a gas with a large specific heat capacity is selec...
