GAS-COOLED HEAT RADIATION SHIELDS IN CLOSED REFRIGERATION CYCLES.

[In German. / En allemand.]

Author(s) : GERHOLD J.

Type of article: Article

Summary

TO ENSURE GOOD LOW TEMPERATURE INSULATION PROPERTIES THE HEAT RADIATION MUST BE LIMITED. WITH VERY LARGE CLOSED SYSTEMS THE TOTAL REFRIGERATION POWER MAY BE REDUCED SIGNIFICANTLY USING SEPARATELY REFRIGERATED SHIELDS COMPLETED BY SUPERINSULATION. USUAL REFRIGERATORS OF MEDIUM SIZE HOWEVER ARE NOT PROPERLY EQUIPPED TO COOL SHIELDS SEPARATELY. SHIELD COOLING MAY BE EFFECTED VERY SIMPLY BY GAS TAKEN FROM THE COLD END OF THE REFRIGERATOR AND FED BACK WITH AMBIENT TEMPERATURE. OPTIMUM DESIGN PARAMETERS ARE DISCUSSED AND QUANTITATIVE DATA FOR HELIUM REFRIGERATORS ARE GIVEN.
