    摘要： A heat transport system includes a fluid, a heat engine, and a component. The fluid has a first fluid region at a first temperature and a second fluid region at a second temperature that is different from the first temperature. The heat engine includes a shape-memory alloy disposed in contact with each of the first fluid region and the second fluid region. The heat engine is operable to transfer heat from one of the first fluid region and the second fluid region to the other of the first fluid region and the second fluid region in response to the crystallographic phase of the shape-memory alloy.

    摘要： A device is provided that may be adapted to control or monitor the pressure level of a fluid system. The device includes a member composed of a shape memory alloy in a superelastic state. The member is configured to undergo a phase change from a high modulus Austenitic phase to a low modulus Martensitic phase and stretch in response to an activation stress. In one embodiment, the member defines two ends such that one end of the member is operatively connected to a fixed point. Another end of the member is operatively connected to a movable element. As the member stretches in response to the activation stress, the movable element is translated relative to the fixed point. In another embodiment, the member includes two plates with respective holes that are selectively aligned when the first and second plates stretch or deform in response to the activation stress.

    摘要： A vehicle includes a fluid mixing system. The fluid mixing system includes a fluid and a heat engine. The fluid has a first fluid region at a first temperature and a second fluid region at a second temperature that is different from the first temperature. The heat engine includes a shape-memory alloy disposed in heat exchange contact with each of the first fluid region and the second fluid region. The heat engine is operable to mix the fluid between the first fluid region and the second fluid region in response to a change in the crystallographic phase of the shape-memory alloy to reduce the difference in the composition of the fluid bath between the first fluid region and the second fluid region.

    摘要： A device and method for controlling a phase transformation temperature of a shape memory alloy is provided. The device includes a primary wire composed of the shape memory alloy. The primary wire defines first and second ends, the first end being attached to a fixed structure and the second end being able to displace. An activation source is thermally coupled to the wire and is operable to selectively cause the primary wire to reversibly transform from a Martensitic phase to an Austenitic phase during a cycle. A loading element is operatively connected to the primary wire and configured to selectively increase a tensile load on the primary wire when an ambient temperature is at or above a threshold temperature, thereby increasing the phase transformation temperature of the primary wire.
