| 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: n nR f —O—R h —O—R f ′nwherein: O is oxygen; n R f and R f ′ are, independently, a fluoroaliphatic group, wherein each R f and R f ′ contain 1 hydrogen atom; R h 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—CH 2 —O—. Another embodiment of the present invention is a method therefor. |
