Abstract
Disclosed are liquid coolants for electric systems and methods of making the same. An example liquid coolant for electric systems may comprise: a base oil, wherein the base oil is a major component of the liquid coolant; and a dissolved gas in an amount sufficient to have a measurable effect on fluid viscosity of the liquid coolant; wherein the liquid coolant has a kinematic viscosity at 100° C. of about 7 cSt or less.
Claims24
A liquid coolant for electric systems, comprising:
- a base oil, wherein the base oil is a major component of the liquid coolant;
- and a dissolved gas in an amount sufficient to have a measurable effect on fluid viscosity of the liquid coolant;
- wherein the liquid coolant has a kinematic viscosity at 100° C. of about 7 cSt or less.
A method of producing a liquid coolant, comprising:
- introducing a base oil into a container;
- and pressuring the container with a gas such that a volume of the gas dissolves into the base oil to provide the liquid coolant;
- wherein the liquid coolant has a kinematic viscosity at 100° C. of about 7 cSt or less.
(canceled)
A method of cooling an electric system, comprising:
- circulating a liquid coolant into a contact with one or more components of the electric system, wherein the liquid coolant comprises:
- a base oil, wherein the base oil is a major component of the liquid coolant;
- and
- a dissolved gas, wherein the dissolved gas is present in the liquid coolant in an amount sufficient to have a measurable effect on fluid viscosity of the liquid coolant;
- wherein the liquid coolant has a kinematic viscosity at 100° C. of about 7 cSt or less.
