On April 6, 2022, HUST-NUS “High Performance Direct Chip Liquid Cooling for Effective Co-Management of Temperature, Power and Performance of Next Generation Electronics” was held online. Invited by prof. Jiang Puqing of the School of Energy and Power Engineering (EPE), Prof. Lee Poh Seng, Associate Professor in the Department of Mechanical Engineering at NUS, delivered a speech online. This seminar was also the second academic activity to celebrate the 70th anniversary of EPE. The meeting was hosted by Prof. Yang Ronggui of EPE, with more than 500 scholars and students attending online.
Prof. Yang Ronggui making an introduction of the seminar
Prof. Lee introduced the current trend of the data center and the performance and prospect of direct chip liquid cooling. Prof. Lee’s research group proposed the idea of diagonal rib by observing that the convective heat transfer at the inlet of the microchannel is higher than that at the fully developed section. The introduction of secondary flow destroys the flow boundary layer, maintaining high convective heat transfer both at the fully developed section and the inlet of the microchannel, thus strengthening the convective heat transfer of the whole microchannel. Prof. Lee then demonstrated the application of liquid cooling technology in server thermal management and elaborated on its important role in the co-management of temperature, power, and performance of next-generation electronics.
Prof. Lee delivering a speech
At the end of the lecture, faculty members and students discussed with Prof. Lee some questions such as reactor coolant and the application of the technology to industry. The seminar triggered participants’ creativity and deepened their understanding of chip cooling technology. The lecture has also improved the discipline development of EPE and HUST.
