Abstract

The present invention provides an apparatus comprising a device and a mechanism for heat transfer comprising a hydrofluoroether heat-transfer fluid wherein the heat transfer fluid is represented by the following structure:Rf—O—Rh—O—Rf′wherein: O is oxygen; Rf and Rf′ are, independently, a fluoroaliphatic group, wherein each Rf and Rf′ contain 1 hydrogen atom; 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 of the present invention is a method therefor.
