Thermal Design for Smartwatches: Ensuring Performance and Safety with Ansys
Explore the application of Ansys Discovery™ 3D product simulation software and Ansys Mechanical™ structural finite element analysis software in addressing thermal management challenges in the design of a smartwatch for triathletes. This case study delves into thermal simulation techniques to analyze heat transfer mechanisms—conduction, convection, and radiation—under real-world conditions, including standing, running, swimming, and cycling. Ansys Discovery software facilitates rapid early-stage design exploration, allowing engineers to quickly identify promising design directions and potential thermal risks. Subsequently, Ansys Mechanical software is employed to validate these designs with advanced techniques, ensuring detailed examination of transient thermal behaviors and high-fidelity results. Key design features, such as an aluminum disc for heat dissipation and optimized insulator thickness, are validated to maintain skin-contact temperatures below the safety threshold of 49°C. This comprehensive approach underscores the robust simulation capabilities of Ansys tools, offering valuable insights to optimize wearable device designs for reliability, safety, and performance in extreme operational scenarios.
