Special Issue Information

Dear Colleagues,

Thermal management in micro/nanosystems is hailed as a revolutionary field for practical applications. According to Moore’s law, the size of electronic devices and circuitry is decreasing, and their number keeps increasing. The resultant change on thermal management will challenge device performance, including measurement reliability and durability of material component stability, electric transports, and data communication. Discovering and understanding thermal properties in micro- and nanoscale devices and realizing an efficient performance of micro/nanosystems is fundamentally important to harnessing thermal management in the field of micro/nanoelectronics. This Special Issue will cover fundamental thermal transport theory and modeling of micro/nanosystems and elucidate how thermal management can improve device performance. Interdisciplinary topics in thermal science at the interaction of electrical engineering, mechanical engineering, materials science, and physics will be welcomed to accelerate the understanding of thermal management in micro/nanosystems.

Heat generation is a major issue in all electronics, as heat reduces product life, reliability, and performance, especially in flexible electronics with low thermal-conductivity polymeric substrates. In this sense, the active heat dissipation design with flow channels holds great promise. Here, a theoretical model, validated by finite element analysis and experiments, based on the method of the separation of variables, is developed to study the thermal behavior of the active heat dissipation design with an embedded flow channel. The influences of temperature and flow velocity of the fluid on heat dissipation performance were systematically investigated. The influence of channel spacing on heat dissipation performance was also studied by finite element analysis. The study shows that performance can be improved by decreasing the fluid temperature or increasing the flow velocity and channel density. These results can help guide the design of active heat dissipation with embedded flow channels to reduce adverse effects due to excessive heating, thus enhancing the performance and longevity of electronic products.
