Abstract
Disclosed herein is a heat transfer system comprising a circulation loop defining a flow path for a heat transfer fluid, and a heat transfer fluid comprising a liquid coolant, a siloxane corrosion inhibitor of formula R3-Si—[O—Si(R)2]x-OSiR3, wherein R is independently an alkyl group or a polyalkylene oxide copolymer of 1 to 200 carbons, x is from 0 to 100, and further wherein at least one alkyl group and at least one polyalkylene oxide copolymer are present, and a non-conductive polydiorganosiloxane antifoam agent, wherein the conductivity of the heat transfer fluid is less than about 100 μS/cm, and wherein the heat transfer system comprises aluminum, magnesium, or a combination thereof, in intimate contact with the heat transfer fluid.
