HYDROFLUOROETHER AS A HEAT-TRANSFER FLUID

摘要

The present invention comprises a compound represented by the following structure: Rf-O-Rh-O-Rf' wherein: O is oxygen; Rf and Rf' are, independently, a perfluoroaliphatic group; and Rh is independently a linear, branched or cyclic alkylene group having from 2 to about 8 carbon atoms and at least 4 hydrogen atoms, and wherein the hydrofluoroether compound is free of -O-CH2-O-. Another embodiment is an apparatus comprising a device and a mechanism for heat transfer comprising a hydrofluoroether heat-transfer fluid. Another embodiment of the present invention is a method for heat transfer.
