Abstract: The present disclosure relates to a heat switch device using a cryogenic loop heat pipe and a method therefor, and more specifically, to a heat switch device using a cryogenic loop heat pipe and a method therefor, wherein the cryogenic loop heat pipe is configured to be operable at a cryogenic temperature, the heat switch device can perform the operation of a heat switch for heat transfer and heat blocking, by using the structure of the cryogenic loop heat pipe, without a separate heat switch, thereby reducing the weight and complexity of a system, compared to a conventional configuration, the heat switch can be operated at a user's desired time, and the heat switch device can be used even in a cryogenic environment, and performs heat exchange by using a gas-liquid phase change, thereby effectively providing high heat transfer and heat blocking effects.

Abstract: Provided is a device for implementing a space environment. More specifically, in order to implement a space environment, while a shroud is disposed inside a vacuum container, an internal pressure of the shroud is controlled to adjust a saturation temperature of working fluid by forming a closed system including a cryogenic refrigerator. As a result, the environment can be implemented at a required temperature. At this time, the pressure can be adjusted by supplying room-temperature gas as working fluid into the closed system, which may result in costs being reduced because there is no need to manage a liquid bombe, and the working fluid injected inside can be used in a recycled manner.
