ABSTRACT:
A cooling apparatus for articles operated at low temperatures comprises a refrigerating machine and a cold head provided in the refrigerating machine. A first Peltier element is thermally contacted and fixed with the cold head, and a second Peltier element is thermally contacted and fixed with the cold head. A first article can be arranged with the first Peltier element with being thermally contacted therewith, and a second article can be arranged with the second Peltier element with being thermally contacted therewith. The cold head is cooled to low temperatures by the refrigerating machine, and temperatures of the first article and the second article each is further controlled by the first Peltier element and the second Peltier element, respectively, to thereby cool the articles to different temperatures.
