An apparatus is provided that includes a device and a mechanism for heat transfer. The mechanism includes a hydrofluoroether heat-transfer fluid wherein the heat transfer fluid is represented by the following structure:
Y—R
f
—CH
2
OCH
2
R
f
—Y
wherein R
f
may be the same or different and is, independently, selected from the group consisting of perfluorinated alkylene groups which may be linear, cyclic, or branched having from 1 to 10 carbon atoms, partially fluorinated alkylene groups having from 1 to 10 carbon atoms, and derivatives thereof wherein one or more carbon atoms are replaced by catenated nitrogen or oxygen heteroatoms, wherein each R
f
contains at most one hydrogen atom, wherein Y represents H, F, or an R
f
CH
2
OCH
