The principal of the University of Hong Kong, Zhang Xiang, has been known for his research on the "nano cloak". The school announced today (12) that Zhang Xiang had new scientific findings. Before taking office, Zhang Xiang was a professor of mechanical engineering at the University of California, Berkeley. At the time, the research team led by him took 5 years of experiments and finally confirmed that thermal energy can be conducted in a complete vacuum, subverting one of the basic concepts of classical physics In the future, it may help reduce and reduce the computer electronic equipment that needs heat dissipation.

In daily life, people use vacuum insulated thermos cups to hold tea or coffee to keep the temperature of the drink, because according to the principle of physics, vacuum hinders heat conduction.

However, the University of Hong Kong announced today that the latest research by Professor Zhang Xiang's research team led by the University of California at Berkeley shows that due to a quantum mechanical phenomenon called the "Casimir effect", thermal energy can span a completely vacuum space of hundreds of nanometers The research results were published in a new issue of the international authoritative academic journal Nature.

The University of Hong Kong refers to the fact that although the "Casimir effect" has a significant effect in a short distance, research is sufficient to have a profound impact on calculator chips and other nano-level electronic components that are designed with heat dissipation as a key consideration. Taking research as a starting point, in the future, by controlling the "quantum vacuum", the heat in the integrated circuit can be dissipated, or it can help reduce and reduce the computer and electronic equipment that needs heat dissipation.
