Abstract
A cooling assembly adapted for use with an exothermic system, includes a manipulable cooling member and/or source, and an active material element operable to selectively inter-engage or further engage the member or source and the system through displacement or formation of a thermal link.
Claims20
A cooling assembly adapted for use with an exothermic system presenting an ambient rate of cooling, and for selectively accelerating the rate, said assembly comprising:
- a cooling member operable to accelerate the rate, so as to cool the system, when engaged or further engaged therewith;
- and
- a first active material element external to the system, and operable to undergo a reversible change in fundamental property when exposed to or occluded from an activation signal, and communicatively coupled to the member,
- said change being configured to selectively cause the member and system to be engaged or further engaged.
