    摘要： An exhaust system configured for converting thermal energy to mechanical energy includes a source of thermal energy provided by a temperature difference between an exhaust gas having a first temperature and a heat sink having a second temperature that is lower than the first temperature. The exhaust system also includes a conduit configured for conveying the exhaust gas, a heat engine disposed in thermal relationship with the conduit and configured for converting thermal energy to mechanical energy, and a member disposed in contact with the conduit and configured for conducting thermal energy from the conduit to the heat engine. The heat engine includes a first element formed from a first shape memory alloy having a crystallographic phase changeable between austenite and martensite at a first transformation temperature in response to the temperature difference between the exhaust gas and the heat sink.

    摘要： A method of controlling an energy harvesting system that converts excess thermal energy into mechanical energy and includes a Shape Memory Alloy (SMA) member, includes obtaining current operational parameters of the energy harvesting system, such as a maximum temperature, a minimum temperature and a cycle frequency of the SMA member. The current operational parameters are compared to a target operating condition of the energy harvesting system to determine if the current operational parameters are within a pre-defined range of the target operating condition. If the current operational parameters are not within the pre-defined range of the target operating condition, then a heat transfer rate to, a heat transfer rate from or a cycle frequency of the SMA member is adjusted to maintain operation of the energy harvesting system within the pre-defined range of the target operating condition to maximize efficiency of the energy harvesting system.

    摘要： An energy harvesting system comprises a first region having a first temperature and a second region. A conduit is located at least partially within the first region. A heat engine configured for converting thermal energy to mechanical energy includes a shape memory alloy forming at least one generally continuous loop. The shape memory alloy is disposed in heat exchange contact with the first region and the second region. The shape memory alloy is driven to rotate around at least a portion of the conduit by the response of the shape memory alloy to the temperature difference between the first region and the second region. At least one pulley is driven by the rotation of the shape memory alloy, and the at least one pulley is operatively connected to a component to thereby drive the component.
