Field of the Invention The present invention relates to an optical fiber cooling device through cooling gas circulation. In particular, the cooling member is dualized to circulate, thereby maintaining a low temperature of the cooling gas to improve cooling efficiency, and cooling in the cooling device by forced circulation. The present invention relates to an optical fiber cooling apparatus through a cooling gas circulation, wherein the gas velocity is increased to increase the heat transfer coefficient in the heat exchange between the optical fiber and the cooling gas to increase the cooling efficiency.
광섬유는 고온의 모재로부터 가늘게 인선된다.The optical fiber is thinly drawn from the high temperature base material.

이하에서 도면을 참조로 본 발명을 보다 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
도 2는 본 발명의 장치를 나타낸 단면도로서,2 is a cross-sectional view of the device of the present invention;
광섬유(3)가 관통되는 공간부(3)를 갖으며, 상기 공간부(3)로 냉각물질이 순환되고, 제 1 내벽(11)과 제 1 외벽(12) 사이로 냉각수가 흐르는 제 1 냉각부재 (10)와; 상기 제 1 냉각부재(10)에 연결되어 냉각물질을 재순환 시키는 공간부(23)를 갖고, 제 2 내벽(21)과 제 2 외벽(22) 사이로 냉각수가 흐르는 제 2 냉각부재 (20)를 포함하여 구성한다.A first cooling member having a space portion 3 through which the optical fiber 3 penetrates, and a cooling material is circulated through the space portion 3 and a coolant flows between the first inner wall 11 and the first outer wall 12. 10; And a second cooling member 20 connected to the first cooling member 10 and having a space 23 for recirculating the cooling material, and flowing coolant between the second inner wall 21 and the second outer wall 22. To configure.
상기와 같이 구성하는 본 발명은 광섬유(3)를 냉각시키는 수단으로 제 1 냉각부재(10)와 제 2 냉각부재(20)를 구비하고, 상기 제 1 냉각부재(10)를 광섬유(3)가 통과하도록 하고, 동시에 제 1 냉각부재(10)와 제 2 냉각부재(20) 사이를 냉각물질 및 냉각수가 흐르도록 하였다.The present invention configured as described above comprises a first cooling member 10 and a second cooling member 20 as a means for cooling the optical fiber 3, wherein the first cooling member 10 is an optical fiber (3) At the same time, the cooling material and the cooling water were allowed to flow between the first cooling member 10 and the second cooling member 20.
이를 위해 상기 제 1 냉각부재(10) 및 제 2 냉각부재(20)는 각각 외벽(12, 22)과 내벽(11, 21)을 구비하고 있으며, 내벽 안쪽으로 형성되는 공간부(13, 23)를 통해 헬륨등과 같은 냉각물질이 순환하고, 외벽(12, 22)과 내벽(11, 21) 사이로는 냉각수가 순환하도록 한 것이다.To this end, the first cooling member 10 and the second cooling member 20 are provided with outer walls 12 and 22 and inner walls 11 and 21, respectively, and space portions 13 and 23 formed inside the inner wall. Cooling material, such as helium through the circulation and the cooling water is circulated between the outer wall (12, 22) and the inner wall (11, 21).
그리고, 제 2 냉각부재(20)에는 강제 순환팬(24)을 설치하여 냉각물질을 강제로 순환시킴으로서 제 1 냉각부재(10)에 빠른 속도로 냉각물질이 투입되어 광섬유(3)의 효율적인 냉각이 이루어지도록 하였다.In addition, a forced circulation fan 24 is installed in the second cooling member 20 to force the cooling material to circulate, thereby allowing the cooling material to be injected into the first cooling member 10 at a high speed so as to efficiently cool the optical fiber 3. It was done.
그리고, 제 1 냉각부재(10)의 상하부에는 실링커버(14, 15)를 부착하였는바, 상기와 같이 실링커버를 부착하게 되면 냉각물질을 이루는 기체가 빠져 나가는 것을 최소화 할 수 있으며, 아울러 장시간 냉각장치를 구동하여 냉각물질이 어느정도 빠져 나가면 제 2 냉각부재(20)에 설치된 냉각가스 보충관(25)을 이용하여 냉각물질을 보충할 수 있도록 하였다.In addition, the sealing covers 14 and 15 are attached to upper and lower portions of the first cooling member 10. When the sealing covers are attached as described above, the gas forming the cooling material can be minimized and the cooling is performed for a long time. When the cooling material is driven out to some extent by driving the device, the cooling material can be replenished by using the cooling gas supplement pipe 25 installed in the second cooling member 20.
결국, 본 발명의 장치는 냉각장치에 공급되는 열교환 매체의 사용량을 기존 냉각 장치보다 적게 하면서, 고속 인선에 적용할 수 있도록 효율을 높인 광섬유 냉각장치이다.As a result, the apparatus of the present invention is an optical fiber cooling apparatus having high efficiency to be applied to a high speed edge line while using less heat exchange medium supplied to the cooling apparatus than the existing cooling apparatus.
따라서, 본 발명의 장치는 강제 순환 장치를 통한 내부의 열교환 매체의 외부로의 유출을 최대한 억제하여 사용량을 최소화 한다.Therefore, the apparatus of the present invention minimizes the amount of usage by restraining the outflow of the heat exchange medium from the inside through the forced circulation device to the outside as much as possible.
기존의 장치는 공급되는 냉각 가스는 광섬유 입출구 부분의 광섬유와 조리개형 실링 장치의 틈을 통해 외부로 빠져 나가게 되는데, 강제 순환 방식을 통하여 이렇게 빠져 나가는 대부분의 냉각가스를 재순환시켜 사용량을 줄일 수 있다.Conventional devices are supplied with the cooling gas is discharged to the outside through the gap between the optical fiber and the aperture type sealing device of the optical fiber inlet and outlet portion, it is possible to reduce the consumption by recycling the most of the cooling gas through the forced circulation method.
본 발명의 장치는 순환되는 내부의 냉각 가스의 온도를 냉각수 등을 이용하여 낮게 유지하고, 강제 순환을 통한 유속의 증가를 통하여 냉각 효율을 증가시킬 수 있다.The apparatus of the present invention can keep the temperature of the cooling gas inside the circulation low by using the cooling water or the like, and increase the cooling efficiency by increasing the flow rate through the forced circulation.
일반적으로 고체와 기체의 표면에서의 열교환은 다음과 같은 식으로 표현된다.In general, heat exchange at the surface of a solid and a gas is expressed by the following equation.
Q = h * A * (Tsolid- Tgas)Q = h * A * (T solid -T gas )
위의 식에서 h는 대류 열전달 계수를 의미하며, A는 고체의 표면적 그리고 Tsolid와 Tgas는 각각 고체의 온도와 기체의 온도를 나타낸다.Where h is the convective heat transfer coefficient, A is the surface area of the solid and T solid and T gas are the solid temperature and the gas temperature, respectively.
냉각수의 온도를 강제 순환시 낮게 유지하면 열전달 값은 커짐을 알 수 있으며, 또한 대류 열전달 계수인 h값은 기체의 유속이 커지면 증가한다고 알려져 있다.It is known that if the temperature of the cooling water is kept low during forced circulation, the heat transfer value increases, and the h value, the convective heat transfer coefficient, increases as the gas flow rate increases.
본 발명은 이 두가지를 구현하여 강제순환을 이용한 냉각장치의 효율을 기존장치에 비하여 증가시킨다.The present invention implements these two to increase the efficiency of the cooling device using forced circulation compared to the existing device.
상술한 바와 같이 구성되는 본 발명의 냉각 가스 순환을 통한 고효율 광섬유 냉각장치는 광섬유와 냉각 장치의 틈을 통해 외부로 유출되는 냉각 가스의 양을 감소시켜 냉각 가스의 사용량을 줄일 수 있도록 하게 하여 준다.The high efficiency optical fiber cooling device through the cooling gas circulation of the present invention configured as described above allows the amount of cooling gas to be reduced by reducing the amount of cooling gas flowing out through the gap between the optical fiber and the cooling device.
동시에 순환되는 동안에 순환장치의 외부를 냉각수 등을 이용하여 냉각하여 냉각 가스의 온도를 낮게 유지하여 냉각 효율을 향상시키며, 강제 순환에 의해 냉각 장치 내에서의 냉각 가스의 속도를 증가시켜서, 광섬유와 냉각가스의 열교환에서 열전달 계수를 크게 하여 냉각 효율을 높이는 효과가 있다.While circulating at the same time, the outside of the circulator is cooled by using coolant or the like to keep the temperature of the cooling gas low to improve the cooling efficiency, and by increasing the velocity of the cooling gas in the cooling apparatus by forced circulation, the optical fiber and the cooling In the heat exchange of the gas, the heat transfer coefficient is increased to increase the cooling efficiency.
