Abstract
Disclosed are systems and methods of rapidly cooling thermal loads by providing a burst mode cooling system for rapid cooling. The burst mode cooling system may include a complex compound sorber configured to rapidly absorb ammonia. The system may be used to provide pulses of cooling to directed energy systems, such as lasers and other systems that generate bursts of heat in operation.
Claims28
A burst mode thermal sorption system configured to provide pulses of cooling to a directed energy apparatus, the system comprising:
- at least one sorber comprising a complex compound sorbent configured to absorb and desorb refrigerant;
- at least one heat source thermally connected to the at least one sorber;
- one or more condensers in fluid communication with the at least one sorber;
- one or more evaporators in fluid communication with the at least one sorber;
- a directed energy apparatus configured to generate bursts of heat to create a thermal load, wherein the directed energy apparatus is in thermal communication with the evaporator;
- and
- a burst mode controller configured to:
- receive a predetermined signal related to the directed energy apparatus, and
- activate a valve, in response to receiving the predetermined signal, to begin an absorption cycle, wherein the absorption cycle comprises a plurality of refrigerant pulses, with each pulse within the absorption cycle including a pulse of refrigerant followed by a rest period.
6 more elements
A method of cooling a directed energy apparatus, the method comprising:
- detecting when to initiate an absorption cycle of a thermal sorption system, wherein the thermal sorption system is in thermal communication with the directed energy apparatus;
- and
- initiating the absorption cycle, in response to detecting when to activate the burst mode cooling cycle, wherein the absorption cycle comprises a plurality of refrigerant pulses, with each pulse within the absorption cycle including a pulse period of refrigerant followed by a rest period.
