Microfluidic devices can offer the potential of automating a wide range of chemical and biological operations for diagnostic and therapeutic operations, whilst providing higher efficiency, repeatability, and reproducibility. Nanoscale heat transfer effects have significant implications for the microelectronic and microphotonic industries, from the thermal management and active cooling considerations to the device design and reliability. Experimental studies have shown micro and nano-structured heat transfer devices have several proper features in comparison to conventional devices, such as the ability to create a very high heat transfer coefficient, being very small in size, and requiring a lower amount of cooling fluid.
The research field of micro and nano-structured heat transfer devices combines the study of both design parameters and coolant properties. Approaches for micro and nanofluidic device fabrications can take the form of various methods in order to design the micrometric structures, such as channels, chambers, and wells. As advancements in the fields of electronics and machine building continue to occur, various structures of such devices are produced today with the aim of increasing the heat transfer coefficient and expanding their field of application. Additionally, these passive enhancement methods are often combined with modern cooling fluids in order to intensify heat transfer. However, using these methods while increasing thermal efficiency can lead to a drop in flow pressure and the increased consumption of energy. Therefore, it is necessary to pay attention to optimizing energy usage whilst using passive enhancement methods.
This Research Topic aims to highlight recent advances in passive enhancement techniques for the thermal efficiency of micro and nano-structured heat transfer devices, with the focus being on optimizing energy usage whilst using passive enhancement methods.
