Abstract: The present invention provides a thermal management system comprising a housing having an interior space; a heat-generating component disposed within the interior space; a heat exchanger; and a working fluid liquid disposed within the interior space wherein the heat-generating component is in contact with the working fluid. The working fluid comprises a Fischer-Tropsch derived base fluid; an antioxidant and anti-static additives. The system is constructed wherein a constant cyclical flow of working fluid is maintained across the heat-generating components, on to the heat exchanger and then back to the heat-generating component.

Abstract: Electrical oil formulation comprising a base oil component and an additive, wherein (i) at least 80 wt % of the base oil component is a paraffin base oil having a paraffin content of greater than 80 wt % paraffins and a saturates content of greater than 98 wt % and comprising a series of iso-paraffins having n, n+1, n+2, n+3 and n+4 carbon atoms and wherein n is between 20 and 35; and (ii) an anti-oxidant additive; wherein the base oil component has a flash point of at least 170° C., as determined by ISO 2592.
