Abstract

Abstract: With the miniaturization of electronic products, heat dissipation has gradually become a focus issue. Most current heat sinks use sensors to detect temperature. After reaching a certain threshold, the sensor generates a signal to drive the motor to drive the heat sink blades to rotate to achieve heat dissipation. This kind of heat dissipation method is more commonly used, but the sensor's anti-interference ability is poor, and the heat dissipation device works at a higher temperature for a long time, the service life will gradually decrease, and the sensing and feedback structure is more complicated and prone to damage. In view of the shortcomings of the above existing products, this article uses the material characteristics of shape memory alloy springs to creatively design a green intelligent heat sink that combines memory alloy springs with sprocket drives. The device uses a memory alloy spring to sense the heat source, and makes full use of its mechanical characteristics to drive the blades of the radiator to rotate, ultimately achieving the purpose of heat dissipation. Experiments and simulation analysis on the operation of the device were conducted to further demonstrate its feasibility, and the benefit analysis and application prospects of the device were clarified through the benefit analysis.
