Abstract:
1. A system for controlling a temperature of a downhole component, the system comprising: a carrier configured to be disposed in a borehole in an earth formation, the carrier including a downhole component; a cooling material in thermal communication with the downhole component, the cooling material including water; and a container disposed in the carrier, the container configured to house the cooling material therein, the cooling material configured to undergo an endothermic reaction and decompose at least the water into hydrogen and oxygen constituents at a selected temperature without reliance on a chemical intermediary, the endothermic reaction and cooling material configured to absorb heat from the downhole component and maintain the downhole component at or below a selected temperature; and a catalyst configured to lower a decomposition temperature, at which the water decomposes without reliance on a chemical intermediary, to the selected temperature.
