摘要:
The present invention comprises a device which utilizes catalytic microcombustion for the production of heat or power and which exhibits a low pressure drop and has a high catalytic surface area. The catalytic microcombustor includes catalyst inserts in the reaction chamber separated by a sub millimeter distance. Thermal spreaders ensure temperature uniformity and maximum thermal efficiency. A mixing zone is prior to the combustion zone. Thermally conductive and/or insulating inserts are in the vicinity of the reaction zone.

A heat sink is used to absorb heat produced by a vehicle. The heat sink uses a steam reformer to create an endothermic reaction between two fluids. Excess heat from the vehicle's engine is used to heat the reactor to facilitate the endothermic reaction. In some embodiments, the reactant fluids are pre-heated by absorbing heat from various components of the vehicle. Excess heat from the various components or from the vehicle engine is used to vaporize the fluids before the fluids enter the reactor.
摘要:
A system for rejecting heat from equipment using endothermic isomerization. includes a heat exchanger configured to receive an elevated-temperature process fluid and an isomerization compound capable of endothermic isomerization. When the system is in operation, heat from the elevated temperature process fluid is transferred to the isomerization compound and the isomerization compound endothermically isomerizes to a higher energy state form. A vehicle includes an engine and a body. The body houses a catalytic heat exchanger having an output in fluid communication with the engine, a pump for urging an isomerization compound into the heat exchanger, and a heat sink controller for controlling the pump. A method for rejecting heat from equipment using endothermic isomerization includes providing a compound capable of endothermic isomerization and transferring heat from a process fluid to the compound, such that the compound endothermically isomerizes to a higher energy level isomer.
摘要:
Systems and methods for rejecting waste heat generated by one or more operating systems installed on an aircraft employ an endothermic fuel that can participate in endothermic catalytic cracking at temperatures below about 80° C. when exposed to a cracking catalyst that contains a superacid operative to induce low-temperature catalytic cracking of the branched alkanes. The endothermic fuel contains an effective amount of the branched alkanes so that a net endothermic effect is realized when the fuel is exposed to the cracking catalyst. The low-temperature, heat-consuming cracking of the branched alkanes increases the heat sink capacity of the endothermic fuel.
