Patent ID: 8808241

Claim:
A cooling device comprising: a target fluid inlet; a target fluid outlet; a plurality of inner conduits fluidly communicating with the target fluid inlet and the target fluid outlet, the plurality of inner conduits providing a plurality of respective flow paths for a target fluid to be cooled; and a chamber surrounding the plurality of inner conduits and containing a first endothermic reactant, the chamber including a reactant inlet selectively alterable from a closed state to an open state, wherein: in the closed state, the first endothermic reactant is isolated from a second endothermic reactant and no endothermic reaction occurs; and in the open state, the reactant inlet provides a flow path for enabling the second endothermic reactant to come into contact with the first endothermic reactant in the chamber for initiating the endothermic reaction and cooling the target fluid in the plurality of inner conduits.
