New Delhi: Indian Institute of Technology Madras (IIT Madras) and Khalifa University in the UAE have come together to develop a cutting-edge cooling solution that could revolutionize electronics applications.

The researcher's latest invention in mini-channel heat exchangers has been published in the renowned journal Applied Thermal Engineering. The research paper was co-authored by Professor S Vengadesan, Department of Applied Mechanics and Biomedical Engineering. And also IIT Madras and his research student, R Vishnu, along with Dr. Ahmed Alkaabi and Dr Deepak Selvakumar from Khalifa University.

An example of the ongoing Chandrayaan-3 mission, India’s space age has been operating through impressive technological innovations and the miniaturization of electronic components, enabling advanced functionalities. But with extensive use of miniaturized electronic components, both in space missions and consumer electronics can steer to a significant amount of heat generation.

High-performance computing processors can produce significant power, leading to heat loads of over 1 kW, requiring effective heat control; thus, IIT Madras researchers are innovating by utilizing plate electrodes to disrupt flow within micro/mini-channel liquid-cooling systems.

Professor S Vengadesan, Department of Applied Mechanics and Biomedical Engineering, IIT Madras has elaborated on this research “ “The new design developed by this research team uses thin plate electrodes that introduce swirling flows inside mini-channel fluids, which result in the formation of vortices at the boundaries, which in turn facilitates better heat transfer."

The reacher has employed computational methods that simulate fluid flows in three dimensions to authenticate the design. By this students have observed that the chaotic swirling flows effectively disrupted the smooth flow at the walls of the channels, and thereby enhanced heat transfer. The electrodes induce vortices at the boundary layer due to the Onsager-Wien effect and disrupt the smooth flow.

Implementing the use of a gentle electric field to induce swirling flow in minichannels renders which is operationally safe and consumes less power. The study's applications in electronic thermal management, particularly in space technology, are vast. With the electrically driven flow vortices, there was no need for additional geometrical modifications. This design operates without vibration and requires no maintenance.

The team intends to enhance the design's efficiency by exploring various electrode positions and orientations, while also recognizing the potential of the identified mechanism to improve thin-film boiling; furthermore, the team suggests extending the design's applicability to two-phase heat transfer systems.
