Abstract: A shutter system for use in a vehicle. The shutter system comprises a panel mounted on a conduit through which air flows, the panel having a first plurality of apertures for permitting air to flow therethrough; and a grille movably mounted on a surface of the panel, the grille having a second plurality of apertures for permitting air to flow therethrough. In an open position, the grille is aligned with the panel such that the first and second plurality of apertures are aligned to permit air to flow through both the first and second plurality of apertures. In a closed position, the grille is aligned with the panel such that the first and second plurality of apertures are not aligned and air is blocked from flowing through the first and second plurality of apertures. The shutter system comprises a first actuator mechanism coupled to the panel and the grille and comprising a first bias spring and a first shape-memory alloy (SMA) spring. The first actuator mechanism moves the grill between the open position and the closed position.
