Abstract[English]
A passive fluid cooling system is provided including an immersion cooling tank including a volume of fluid; and a shape memory alloy (SMA) heat engine, the SMA heat engine including a plurality of wheels and an SMA wire coupled to the plurality of wheels. A portion of the SMA wire is in contact with the volume of fluid and transitions from a relaxed state to a tightened state when a temperature of the volume of fluid exceeds a transformation temperature of the SMA wire. The tightening of the SMA wire causes the plurality of wheels to rotate and induce motion in the volume of fluid and causes the volume of fluid to decrease in temperature.[French]
L'invention concerne un système de refroidissement de fluide passif comprenant un réservoir de refroidissement par immersion comprenant un volume de fluide ; et un moteur thermique en alliage à mémoire de forme (SMA), le moteur thermique SMA comprenant une pluralité de roues et un fil SMA couplé à la pluralité de roues. Une partie du fil SMA est en contact avec le volume de fluide et passe d'un état relâché à un état serré lorsqu'une température du volume de fluide dépasse une température de transformation du fil SMA. Le serrage du fil SMA amène la pluralité de roues à tourner et à induire un mouvement dans le volume de fluide et amène le volume de fluide à diminuer en température.
