Abstract: A method of determining effective heat transfer capability of a fluid coolant composition, the method comprising the steps of: determining a critical cooling effectiveness percentage value for the fluid coolant composition; and determining whether the critical cooling effectiveness percentage value is greater than zero percent, thereby determining whether the fluid coolant composition has effective heat transfer capability; wherein the critical cooling effectiveness percentage is high enough to indicate an increased heat transfer capability of the fluid coolant composition and is low enough to substantially prevent deleterious effects on other properties of the fluid coolant composition.

Abstract: A fluid composition includes a coolant and a plurality of nanoparticles dispersed within the coolant. The plurality of nanoparticles includes glass, silica, pumices, metal compounds adapted to react with chloride in the coolant, and/or mixtures thereof. The plurality of nanoparticles substantially increases heat capacity of the coolant and enhances heat transfer efficiency of the fluid composition.

Abstract: The present invention relates generally to heat transfer compositions. More particularly, the present invention relates to heat transfer compositions with high electrical resistance for use in power-generating equipment or in engines. Such compositions are particularly useful in fuel cell assemblies.

Abstract: A composition for sealing at least one fluid leak in heat exchange systems comprises at least one solvent, and fibrillated fiber in an amount and of a size sufficient to become entrained in and seal the one leak. At least one corrosion inhibitor is present in an amount sufficient to aid in prevention of corrosion of at least two metals. The corrosion inhibitor is compatible with coolants having organic acid corrosion inhibiting agents therein, and with coolants having silicate corrosion inhibiting agents therein.
