Abstract: A piezoelectric linear motor and an electronic device, including a piezoelectric actuator and an elastic structure fixed to two opposite sides of the actuator. The piezoelectric actuator extends/retracts to drive the elastic structure to move when a voltage is applied. The elastic structure includes sets of elastic connecting portions fixed to end portions of the piezoelectric actuator, each set includes two connecting legs fixed to two opposite sides of the piezoelectric actuator, each connecting leg extends toward an outer side of the piezoelectric actuator, and connecting legs located at a same side of the piezoelectric actuator extend away from each other, and an angle is formed between each of the connecting legs and a plane where the piezoelectric actuator is located. The connecting legs have better flexibility, the elastic structure has stronger deformation capability, a haptic feedback response speed is increased and thickness of the piezoelectric linear motor is reduced.

Abstract: The present invention discloses a high-temperature fluid transporting pipeline with a heat exchange apparatus installed therein, a suitable heat exchange apparatus and a heat exchange method, wherein heat contained in a high-temperature fluid can be recovered during the transportation thereof. The heat exchange apparatus comprises a heat exchange body inserted into the high-temperature fluid transporting pipeline, and a heat-receiving fluid coil installed therein. The method of heat exchange is that the high-temperature fluid heats an auxiliary fluid in a heat exchange cavity via a heat exchange panel of the heat exchange body in contact therewith, and the heated auxiliary fluid then conducts the heat to a heat-receiving fluid in the heat-receiving fluid coil.
