A thermal actuator includes a piston slidably disposed within a cylinder. The piston cooperates with the cylinder to define a cavity. The piston also includes a rod extending away from the cavity. A magnetic field generator selectively applies an alternating magnetic field to the cylinder and inductively heats a heating element mounted within the cavity. The cavity also includes a volume of phase change material that is melted by the heating element. The melted phase change material expands to drive the rod from the retracted position to the extended position.
一种热致动器,包括滑动地设置在圆筒内的活塞。活塞与圆筒配合以限定空腔。活塞还包括远离空腔延伸的杆。磁场发生器选择性地将交变磁场施加到圆筒,并感应地加热安装在空腔内的加热元件。空腔还包括一体积的相变材料,该相变材料被加热元件熔化。熔化的相变材料膨胀以将杆从缩回位置驱动到延伸位置。
