Abstract: PURPOSE: A double step low temperature freezing device is provided to easily control the selective contact between components through contacting a first freezing unit and a freezing object by using a bellows shaped contacting unit. CONSTITUTION: A double step low temperature cooling device(100) is composed of a first freezing unit(112), a second freezing unit(113), and a contact control unit(120). The second freezing unit is contacted to a freezing object for heat exchanging. The second freezing has lower freezing available temperature and smaller freezing capacity than the first freezing unit. The contact control unit selectively secludes the heat exchange between the first freezing unit and a freezing object.
