System and method for rejecting heat from equipment via endothermic isomerization

A system for rejecting heat from equipment using endothermic isomerization, comprising:

• heat-generating equipment situated on-board an aircraft;
• a heat exchanger configured to receive a liquid process fluid and an isomerization compound capable of endothermic isomerization, wherein the liquid process fluid circulates between the heat-generating equipment and the heat exchanger;
• a pump for urging the isomerization compound into the heat exchanger;
• and
• a heat sink controller for controlling the pump;
• wherein, when the system is in operation, the liquid process fluid transfers heat to the isomerization compound and the isomerization compound endothermically isomerizes to a higher energy state form.
