Abstract
Heat transfer fluids were formulated with a neat solution of a synthetic ester base stock. A base stock prepared with a neat ester according to the invention has similar performance characteristics to commercially available heat transfer fluids.
Claims20
A heat transfer fluid comprising a neat ester stock or ester stock blend as a base fluid and an additive.
A heat transfer fluid comprising an ester stock as a base fluid and an additive, wherein the ester stock is:
- a blend of Ex 4, Ex 7, Ex 12 or Ex 14,
- a blend of Ex 4, Ex 7, Ex 12 or Ex 14 as a first ester together with a second ester,
- a blend of Ex 4, Ex 7, Ex 12, Ex 14, or any combination thereof as a first ester together with a second ester that is Ex 26, Ex 27, Ex 28, or any combination thereof,
- wherein the heat transfer additive has an electrical conductivity (ps/m) of between about 1,850 and about 150,000, and a viscosity index of between about 70 and about 120.
A method of cooling an engine comprising use of a heat transfer fluid within the motor, the fluid comprising:
- a neat ester stock of Ex. 4 Ex 7, Ex 12 or Ex 14 in an amount between 80 wt % and 99.9 wt % and an additive in an amount between 0.1 wt % and 20 wt %,
- wherein the heat transfer fluid efficiently cools the portion of the engine with which the fluid is in contact.
