It should be noted that, in order to ensure that the helium gas smoothly enters the air passing cavity from the air inlet diversion member and is smoothly discharged from the air outlet diversion member, in the cooling device, the outer end surface of the flat end surface of the air inlet diversion member body on each cooling pipe half body is slightly lower than the end surface of the corresponding cooling pipe half body (generally lower by 1-3 mm), that is, the air inlet diversion member body is accommodated in the cooling pipe half body, does not protrude out of the cooling pipe half body, and is not flush with the cooling pipe half body. Correspondingly, the flat end surface of the air outlet flow guide part body is slightly lower than the end surface of the inner side of the cooling pipe half body, so that the normal air outlet is ensured.
In an alternative embodiment, a sealing element 25 (typically a sealing strip) may be provided between the two cooling tube halves, and in particular, a sealing element may be provided on each of the two cooling tube plates, the two sealing elements being identical in structure and located on different sides of the cooling tube.

The cooling device provided by the invention greatly enhances the optical fiber cooling effect under the combined action of convection heat transfer (cooling water in the water cavity in the cooling pipe half body conducts heat and cools) and turbulence heat conduction (helium forms turbulence under the blocking of the partition plate to fully take away the heat of the optical fiber). The optical fiber cooling effect is greatly improved, meanwhile, the loss of helium can be reduced, the production efficiency is greatly improved, and the optical fiber production cost is reduced.
it should be noted that the heights of the partition plates arranged on the two cooling pipe half bodies are all arranged in one-to-one correspondence on the same height, so that the air passing holes are formed by the grooves 10 between every two (one pair of) partition plates. Preferably, the groove is a semicircular groove, and the formed air passing hole is concentric with the partition plate.
the optical fiber cooling device can improve the cooling effect on the optical fiber, and recycle the helium gas, thereby improving the production efficiency and reducing the production cost. The gas collecting device 22 is connected to the gas outlet pipe. Usually, the gas collection device adopts a helium recovery device (system), the compressor can be connected with a gas outlet pipeline, the rear end of the compressor is connected with the helium recovery device, gas passing through the air passing cavity is collected, and helium is effectively recovered and purified, so that the aim of recycling is fulfilled, and the expensive helium can be recovered and reused.
When waste gas is recycled, the gas collecting device (compressor) can form certain negative pressure (equivalent to outward air exhaust) on the air passing cavity, so that airflow in the cooling pipe flows upwards, and due to the special structural design of the air inlet guide groove, the airflow is effectively guaranteed to have the trend of upward (air outlet end) movement, and the continuous cooling effect on the optical fiber is realized. Specifically, the gas collecting device can also adopt a commercial cryogenic system, different gases are separated by utilizing different boiling points, and helium gas separation and recovery are realized by a cryogenic separation method.
Before the wire drawing device is used, a water bath box serving as a cooling water circulation device is electrified, circulating water in a water cavity of a cooling pipe starts to circulate, the water temperature is controlled by a compressor, an external helium source interface is opened, helium with a certain flow is introduced into an air inlet pipeline, the flow of the helium can be adjusted in real time according to the actual wire drawing speed, and meanwhile, a gas collection device starts to work.
Preferably, a separation baffle plate 19 is arranged in a water cavity of the cooling pipe half body, and the separation baffle plate separates the interior of the water cavity into an inverted U-shaped structure, and comprises a left water inlet half area 20 and a right water outlet half area 21; the water inlet is arranged at the lower end of the left water inlet half area, and the water outlet is arranged at the lower end of the right water outlet half area. Due to the structural design, the longest path of cooling water flow is ensured, and the cooling effect is optimal.
during normal production, when the wire drawing speed reaches the set speed, when coating temperature can't satisfy the wire drawing speed and continue to promote promptly, close two cooling tube halfbodies, optic fibre passes the air passing chamber (actually being injectd in the air passing hole of baffle) of the cooling tube that forms, behind the gassing helium, helium upwards flows along air passing chamber to one side, meets the part of baffle and can be blockked to retrace, mixes with the gas that normally flows, produces the torrent, and the gas that flows through air passing hole can further flow to next baffle department (be in this baffle top promptly).
preferably, the air outlet pipeline (one end of the air outlet) is arranged at the outermost edge of the air outlet flow guide piece corresponding to the air outlet flow guide groove, so that a better air outlet effect is ensured.
in an optional embodiment, the air holes of the partition plate are sequentially increased from the lower part to the upper part of the cooling pipe (or the air holes of the partition plate in the middle of the half cooling pipe are the largest, and the diameters of the air holes of the partition plate closer to the two ends are smaller from the middle part), so that the flow velocity of the air flow from bottom to top is approximately balanced, because the air flow farther away from the air inlet pipeline is smaller due to the blocking of the partition plate, and the air collecting device is arranged at the air outlet pipeline, so that a certain negative pressure can be formed in the space close to the air outlet end, and therefore, the air flow velocity is generally higher than the air flow velocity at the middle part of the cooling pipe. Due to the structural design, the normal circulation of airflow is effectively guaranteed, and the phenomenon that the cooling efficiency and the cooling effect are reduced due to excessive 'silting' in the middle of the cooling pipe is avoided.
it should be noted that, the cooling device is to intake air from the lower end of the cooling tube, the air flow direction is opposite to the optical fiber movement direction, thereby forming convection heat transfer and enhancing the cooling effect, and compared with the air flow supply mode from top to bottom (i.e. the air flow is consistent with the optical fiber movement direction) in the prior art, the cooling device has better cooling effect.
the cooling device provided by the invention has a simple structure and is convenient to operate, and the optical fiber cooling effect is greatly enhanced under the combined action of convection heat transfer (cooling water in a water cavity in the cooling pipe half body conducts heat and cools) and turbulent heat transfer (helium forms turbulent flow under the blocking of the partition plate to fully take away optical fiber heat). When the optical fiber cooling effect is greatly improved, the loss of helium can be reduced, the production efficiency is greatly improved, the utilization rate of auxiliary materials for production can be increased, and the optical fiber production cost is reduced.
the above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
