Abstract
A cooling device for cooling a test sample has at least two cascade cooling stages, each with at least one coolant line, one compressor (1.1, 2.1), one relief throttle (1.5), one evaporator (6, 7) and one liquefier (3, 6). The coolant line is divided into n partial lines (A, B) between the compressor (2.1) and the liquefier (6) of the last cascade cooling stage, wherein n≧2. Each divided n partial line (A, B) has a valve (2.7, 2.8) and an individual relief throttle (2.5, 2.6). The divided partial lines (A, B) are connected to the evaporator (7) of the last cascade cooling stage. This represents a simple possibility of adjusting the cooling temperature without using valves that must be adjusted in a cold state, since such valves are complex and expensive.
