Abstract | Thermal management systems incorporating shape memory alloy (SMA) actuators and related methods. A thermal management system includes a heat transfer region, a process fluid conduit, a thermal management fluid conduit, and an SMA actuator assembly. The SMA actuator assembly includes an SMA element coupled to an actuation element, which is configured to assume a position among a plurality of positions defined between a restrictive position and an open position. The position of the actuation element is based, at least in part, on a conformation of the SMA element. A method of passively regulating a temperature of a process fluid includes conveying a process fluid stream in heat exchange relation with an SMA element, transitioning the SMA element to assume a conformation, flowing each of the process fluid stream and a thermal management fluid stream through a heat transfer region, and modulating a flow rate of the thermal management fluid stream.
Des systèmes de gestion thermique intégrant des actionneurs dalliage à mémoire de forme (AMF) et des méthodes connexes sont décrits. Un système de gestion thermique comprend une région de transfert thermique, une conduite de fluide de traitement, une conduite de fluide de gestion thermique et un assemblage dactionneur AMF. Lassemblage dactionneur AMF comprend un élément dAMF couplé à un élément dactionnement, qui est configuré pour prendre une position parmi plusieurs positions définies entre une position restrictive et une position ouverte. La position de lélément dactionnement est fondée au moins en partie sur une conformation de lélément dAMF. Une méthode de régulation passive dune température dun traitement de fluide comprend le convoyage dun flux de fluide de traitement en relation déchange de chaleur avec un élément dAMF, la transition de lélément dAMF pour assumer une conformation, la circulation du flux de fluide de traitement et du flux de fluide de gestion thermique dans une région de transfert thermique et la modulation dun débit du flux de fluide de gestion thermique. |
