본 발명은 초전도체 냉각용기용 냉각장치에 관한 것으로서, 더욱 상세하게는, 내용기의 둘레에 평면가공으로 설치면부를 다수개 형성하고, 구리재질의 열전달부재를 설치면부에 설치한 후, 구리 플렉시블부재를 이용하여 열전달부재를 상호 연결하여 냉동기의 냉기를 내용기로 균일하게 전달함으로써, 기존의 구리밴드를 삭제하여 제작 비용을 절감하고, 접촉상태 확인 및 품질관리가 용이하게 이루어지는 초전도체 냉각용기용 냉각장치에 관한 것이다.The present invention relates to a cooling device for a superconductor cooling container. More specifically, the present invention relates to a cooling device for a superconductor cooling container. In more detail, a plurality of installation surface parts are formed around the inner container by planar processing, a heat transfer member made of copper is installed on the installation surface parts, and then a copper flexible member is installed. By connecting the heat transfer members to each other to evenly transmit the cold air from the refrigerator to the contents, manufacturing costs are reduced by eliminating the existing copper band, and the cooling device for superconductor cooling containers is easy to check contact status and quality control. It's about.

일반적으로, 초전도체를 극저온으로 냉각하기 위한 냉각 저온용기는 외부로 부터의 열유입을 최소화하는 진공 단열 구조의 실린더 형태로 제작된다. 냉각 저온용기는 진공상태를 유지하는 외용기와, 외용기의 내부에 구비되고, 초전도체를 극저온으로 냉각하기 위한 내용기를 포함한다.Generally, cooling cryogenic containers for cooling superconductors to cryogenic temperatures are manufactured in the form of cylinders with a vacuum insulation structure that minimizes heat inflow from the outside. The cooling low-temperature container includes an outer container that maintains a vacuum state, and an inner container provided inside the outer container to cool the superconductor to extremely low temperatures.

초전도체는 주로 질소로 이루어진 내용기에 담기어 냉각되는 데, 이때 액체질소를 냉각하기 위해 극저온 냉동기를 사용한다.Superconductors are mainly cooled by being placed in an inner container made of nitrogen, and in this case, a cryogenic refrigerator is used to cool the liquid nitrogen.

이때, 컴팩트한 시스템을 구성하기 위해 내용기인 질소조의 측면(액체질소 상부)에는 냉동기를 부착하여 중력 방향의 액체질소 자연대류를 발생시키고, 질소조 원주방향으로의 온도 균일성을 위해 원형(랑 형상)의 구리밴드를 내용기(질소조) 외벽에 솔더링 또는 브레이징 접합하여 제작한다. 특히, 구리밴드는 일정 두께의 구리 판재를 롤링 및 질소조 외벽과 맞닿는 오목면 밀링작업을 통해 원형으로 제작한다.At this time, in order to construct a compact system, a refrigerator is attached to the side of the nitrogen tank (upper part of the liquid nitrogen) to generate natural convection of liquid nitrogen in the direction of gravity, and a circular (angular) shape is used to ensure temperature uniformity in the circumferential direction of the nitrogen tank. ) is manufactured by soldering or brazing the copper band to the outer wall of the inner container (nitrogen tank). In particular, the copper band is made into a circular shape by rolling a copper plate of a certain thickness and milling the concave surface that contacts the outer wall of the nitrogen tank.

그런데, 종래에는 구리밴드를 제작하는 과정에서, 내용기의 크기가 커질수록 구리밴드의 제작 난이도가 높아지게 되고, 제작비용이 점차 증가하게 되며, 브레이징의 경우 가열을 위한 진공로(眞空爐, vacuum furnace)의 크기에 제한을 받는 문제점이 있다.However, in the conventional process of manufacturing a copper band, as the size of the inner container increases, the difficulty in manufacturing the copper band increases, and the manufacturing cost gradually increases. In the case of brazing, a vacuum furnace for heating is used. ), there is a problem that the size is limited.

또한, 종래에는 구리밴드의 내측면과 내용기의 외측면 사이에 용가재를 이용하여 접합하는 것으로서, 구리밴드의 내측면과 내용기의 외측면에 접착된 솔더링 또는 브레이징 상태 확인에 어려움이 있을 뿐만 아니라, 접합이 제대로 이루어지지 않는 경우 열전달 효율이 현저하게 저하되는 등 품질관리에 어려움이 있다.In addition, in the past, filler metal was used to join between the inner surface of the copper band and the outer surface of the inner container, which not only made it difficult to check the state of soldering or brazing bonded to the inner surface of the copper band and the outer surface of the inner container. , if the bonding is not done properly, there are difficulties in quality control, such as a significant decrease in heat transfer efficiency.

따라서, 이를 개선할 필요성이 요청된다.Therefore, there is a need to improve this.

이하, 첨부도면을 참조하여 본 발명의 일 실시예에 따른 초전도체 냉각용기용 냉각장치의 작용 및 효과를 살펴보도록 한다.Hereinafter, the operation and effect of the cooling device for a superconductor cooling container according to an embodiment of the present invention will be examined with reference to the accompanying drawings.

내용기(200)의 둘레에 원주방향으로 밀링가공을 통해 설정간격을 갖도록 다수개의 평면으로 이루어진 설치면부(410)를 형성하고, 설치면부(410)에 다수개의 볼트부재(432)를 용접으로 고정한다.An installation surface 410 consisting of a plurality of flat surfaces is formed at a set interval through milling in the circumferential direction around the inner container 200, and a plurality of bolt members 432 are fixed to the installation surface 410 by welding. do.

연이어, 구리블록으로 제작된 열전달부재(420)에 볼트부재(432)에 대응되는 위치에 삽입홀부(434)를 형성하고, 삽입홀부(434)에 볼트부재(432)를 삽입하여 너트부재(436)를 이용하여 적절한 토크를 가해 체결하므로 열전달부재(420)를 설치면부(410)에 긴밀하게 밀착할 수 있다.Subsequently, an insertion hole portion 434 is formed in the heat transfer member 420 made of a copper block at a position corresponding to the bolt member 432, and the bolt member 432 is inserted into the insertion hole portion 434 to form the nut member 436. ), so that the heat transfer member 420 can be tightly adhered to the installation surface 410 by applying an appropriate torque.

종래에는 솔더링 또는 블레이징을 이용하여 구리밴드를 내용기의 둘레에 원형으로 설치하므로 용접 상태 확인이 어려울 뿐만아니라, 풀질관리가 어려운 반면에, 본 발명의 경우에는 열전달부재(420)가 설치면부(410)에 가해지는 접촉력을 볼트 너트 결합을 통해 조절하는 것이 가능하므로 품질관리가 용이하게 이루어질 수 있다.Conventionally, the copper band is installed in a circular shape around the inner container using soldering or blazing, so it is difficult to check the welding condition and also difficult to manage the glue quality. However, in the case of the present invention, the heat transfer member 420 is installed on the installation surface ( Since it is possible to control the contact force applied to the 410) through bolt and nut combination, quality control can be easily achieved.
