Claim 8:
9. A method comprising:
circulating a first thermal management fluid in a first fluid circuit and between an electrical heat source and a first portion of a first heat exchanger;
absorbing thermal energy in the first thermal management fluid from the electrical heat source;
dissipating thermal energy from the first thermal management fluid into the first heat exchanger; and
circulating a second thermal management fluid in a second fluid circuit and over a second portion of the first heat exchanger; and
absorbing heat from the first exchanger into the second thermal management fluid:, wherein the second thermal management fluid comprises:
an aqueous carrier fluid; and
a dispersion of micelles within the aqueous carrier fluid, wherein each micelle comprises a solid hydrophobic core particle comprising a phase change material having a melting point in the range of 30° C. to 100° C. and one or more emulsifiers forming a micellar shell around the solid hydrophobic core particle.
