ACTUATOR USING SHAPE MEMORY ALLOY, CAPABLE OF RAPIDLY OPERATING COOLING PERFORMANCE AT A SPEED HIGHER THAN A HEATING OPERATION SPEED

摘要

PURPOSE: An actuator using shape memory alloy is provided to improve a reaction speed as heating fluid or cooling fluid is injected into both ends of a covering material.;CONSTITUTION: An actuator(100) comprises shape memory alloy manufactured into a tube shape with a hollow portion. The heating and cooling units of the actuator cool and heat the shape memory alloy, and control the temperature. The electricity is used as the heating unit, and fluid is used as the cooling unit to control the temperature. The shape memory alloy is manufactured into a coil spring shape.;COPYRIGHT KIPO 2013
