发明名称 REFRIGERATING APPARATUS
摘要 A coolant for use in cryogenic devices of closed cycle system which comprises a mixture of a liquid nitrogen and a fluorocarbon of the formula: CnF2n+2, wherein n is an integer of 2 to 4. The coolant, when used to cool heat generating semiconductor devices and other devices to a cryogenic temperature, exhibits an increased heat flux and thus an increased cooling capability, in addition allows a simple and small structure of the cooling system, and a prevention of environmental pollution.
