Abstract

본 발명은 초전도 발전기와 같이 회전자 내부의 계자권선을 극저온 상태로 유지하기 위해 액체 헬륨 또는 액체질소를 냉매로 사용하는 열교환기에 있어서, 극저온의 냉매를 효율적으로 사용하기 위해 구조가 간단하면서도 열접촉면적을 최대로 증대시켜 열교환효과를 극대화할 수 있는 다공성 매질을 이용한 열교환기를 제공하는 데 있다.The present invention is a heat exchanger using a liquid helium or liquid nitrogen as a refrigerant to maintain the field winding inside the rotor in a cryogenic state, such as a superconducting generator, the structure is simple and thermal contact area to efficiently use the cryogenic refrigerant It is to provide a heat exchanger using a porous medium that can maximize the heat exchange effect to the maximum.

그 구성은 관(10)의 내부에 극저온의 냉매가 흐르는 유로(11)가 구비되어 관(10) 외부의 대기와 열교환이 이루어지도록한 냉매용 열교환기에 있어서, 다공도(Φ)가 20∼40％이고 소정의 길이(L)를 갖는 실린더형태의 다공성 매질(13)을 상기 관(10)의 내경면에 설치하여 냉매가 통과되어 열교환되도록한 것이다.In the heat exchanger for refrigerant in which the flow path 11 through which the cryogenic refrigerant flows is provided inside the tube 10 to exchange heat with the atmosphere outside the tube 10, the porosity Φ is 20 to 40%. And a cylindrical porous medium 13 having a predetermined length L is installed on the inner diameter surface of the tube 10 to allow the refrigerant to pass through and exchange heat.
