The assembly includes a cooling channel disposed within the body and fluidly coupled with a passageway that carries cooling fluid into and out of the cooling channel. At least a portion of the cooling fluid is a liquid phase, a gas phase, or a liquid-gas mix phase. The cooling channel is fluidly separate from the at least one cooling chamber. The cooling channel is thermally coupled with the at least one cooling chamber. The at least one cooling chamber transfers thermal energy from the working fluid to the cooling fluid. ## Claims ### Claim 1 A multi-domain cooling assembly configured to be coupled with one or more heat sources, the multi-domain cooling assembly comprising: a body comprising an outer surface;
