Abstract
A method of cooling a flexible actuator including a coil spring and a plurality of silicone tubes includes providing cooling fluid to the plurality of silicone tubes based on a cooling signal, recovering cooling fluid from the plurality of silicone tubes and re-cooling the cooling fluid, and providing the re-cooled cooling fluid to the plurality of silicone tubes, wherein the flexible actuator is manufactured based on a shape memory alloy, and each of the plurality of silicone tubes is in contact with at least a portion of a plurality of outer circumferential surfaces of the coil spring.
Claims14
A method of cooling a flexible actuator including a coil spring and a plurality of silicone tubings, the method comprising:
- providing a cooling fluid to the plurality of silicone tubings based on a cooling signal;
- recovering the cooling fluid from the plurality of silicone tubings and re-cooling the cooling fluid;
- and
- providing the re-cooled cooling fluid to the plurality of silicone tubings,
- wherein the flexible actuator includes a shape memory alloy, and
- wherein each of the plurality of silicone tubings is in contact with at least a portion of a plurality of outer circumferential surfaces of the coil spring.
A cooling system, comprising:
- a flexible actuator includes a shape memory alloy;
- and
- a cooling device configured to cool the flexible actuator,
- wherein the flexible actuator comprising:
- a coil spring;
- and
- a plurality of silicone tubings in contact with at least a portion of a plurality of outer circumferential surfaces of the coil spring, through which a cooling fluid flows,
- wherein the cooling system is configured to provide the cooling fluid to the plurality of silicone tubings through the cooling device to control a temperature of the coil spring.
