Abstract
The present applications pertains to heat transfer fluids and processes of employing them to, for example, cool electronic devices. In one embodiment, the heat transfer fluids include an alkylene carbonate and at least one organic solvent. Suitable organic solvents include, for example, an alkylene glycol or a glycol ether. The fluids typically are dielectric liquids with less than 30 weight percent of water. Advantageously, the fluids often have an effective beat capacity greater than water which is useful for cooling an electronic device such as a battery, a computer, a server, and the like.
Claims21
A heat transfer fluid comprising:
- (a) an alkylene carbonate;
- and
- (b) at least one organic solvent selected from an alkylene glycol, or a glycol ether;
- and
- wherein the fluid is a dielectric liquid, comprises less than 30 weight percent of water, and has an effective heat capacity greater than water.
A process for heat transfer comprising:
- forming a dielectric fluid comprising an alkylene carbonate and an organic solvent comprising a glycol ether;
- absorbing heat endothermically in a heat exchange;
- releasing heat exothermically in a second heat exchange;
- wherein the formed dielectric fluid comprises a liquid;
- and
- wherein a liquid phase of the formed dielectric fluid has an observed heat capacity that exceeds a calculated heat capacity based on the formed dielectric fluid's composition.
A process for heat transfer comprising:
