Abstract
1,157,296. Heat-transfer liquids. UNION CARBIDE CORP. 30 March, 1967 [1 April, 1966], No. 14510/67. Heading C4X. [Also in Division C7] A cooling agent particularly for quenching metals but applicable also to the extraction of heat from materials such as cermets, ceramics, cements, rubbers or resins consists of a cryogenic fluid (i.e. one whose normal boiling point is below 0‹ C.) or a mixture of such fluids in which is dispersed one or more finely divided materials which are solid at the boiling point of the liquid and themselves have a boiling point within the range -128‹ to 1180‹ C. and a freezing point in the range - 184‹ to 650‹ C., the agent preferably containing 10-70% by weight of the solid additive. By suitable choice of constituents particular cooling rates over desired temperature ranges may be selected. Many suitable substances are listed, but a preferred combustion is ice dispersed in liquid nitrogen. The invention includes a process of extracting heat by means of a cryogenic liquid in which is dispersed at least one finely divided solid having its melting point, and preferably also its boiling point within the range formed by the boiling point of the cryogenic fluid and the temperature of the material to be cooled.
