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.
