Abstract
An apparatus is provided that includes a device and a mechanism for heat transfer that includes a provided hydrofluoroether having high temperature stability. Also provided is a method of transferring heat and a composition that includes a provided hydrofluoroether.
Claims16
An apparatus requiring heat transfer comprising:
- a device;
- and
- a mechanism for transferring heat to or from the device, the mechanism comprising a heat transfer fluid represented by the following structure:
- H(C2F4)xCH2OCF2CFH—Y—Rf
- wherein
- Y is a single bond or a single oxygen atom, and x=1-3,
- wherein when Y is a single bond, then Rf is selected from CF3, C2F5, and n-C3F7,
- wherein when Y is a single oxygen atom, then Rf is a linear, branched, or cyclic perfluoroaliphatic group of 1 to 7 carbon atoms which may, independently, contain one or more catenated heteroatoms such as nitrogen or oxygen, and
- wherein the total number of carbon atoms in the structure is greater than or equal to 9.

A composition comprising a fluid represented by the following structure:
- H(C2F4)XCH2OCF2CFH—O—Rf
- wherein
- x=1-3,
- wherein, Rf is a linear, branched, or cyclic perfluoroaliphatic group of 1 to 7 carbon atoms which may, independently, contain one or more catenated heteroatoms such as nitrogen or oxygen, and
- wherein the total number of carbon atoms in the structure is greater than or equal to 9.
2 more elements
A method of heat transfer comprising:
- providing a device and a mechanism for transferring heat to or from the device;
- the mechanism comprising a heat transfer fluid represented by the following structure:
- H(C2F4)xCH2OCF2CFH—Y—Rf,
- wherein
- Y is a single bond or a single oxygen atom, and x=1-3,
- wherein when Y is a single bond, then Rf is selected from CF3, C2F5, and n-C3F7,
- wherein when Y is a single oxygen atom, then Rf is a linear, branched, or cyclic perfluoroaliphatic group of 1 to 7 carbon atoms which may, independently, contain one or more catenated heteroatoms such as nitrogen or oxygen, and
- wherein the total number of carbon atoms in the structure is greater than or equal to 9;
- and
- transferring heat to or from the device with the mechanism.
