Abstract
A cooling system includes a reactant material, a reactive material, a thermally managed control module, and a plunger. The reactive material is spaced apart from the reactant material. The thermally managed control module is configured to receive coolant from a coolant supply reservoir via a coolant supply channel. The plunger is movable between a retracted position and an extended position. When a temperature of the thermally managed control module is greater than a predetermined temperature, an actuator is configured to transition the plunger from the retracted position to the extended position and cause the reactive material to mix with the reactant material to create a second coolant via an endothermic reaction, and the second coolant enters the thermally managed control module via the coolant supply channel.
