China Science Dawning has developed the first liquid-cooled eight-way server in China. Recently, China Science Dawning Company announced that it has successfully developed the first liquid-cooled eight-way server in China. It is reported that the rack multi-channel server uses cooling technology, through the integrated liquid cold exhaust cycle module, the CPU temperature is controlled at about 50 degree C, the server has 99.999% high reliability and 100,000 hours of trouble-free time. Chinese scholars have developed a liquid metal-driven robot. The University of Science and Technology of China has designed a new type of robot driver based on gallium-based liquid metal at room temperature. It is the first time that a functional wheeled mobile robot driven by liquid metal is realized. The results were published in Advanced Materials magazine recently. Researchers designed a very light and semi-enclosed wheel structure with superhydrophobic surface, which confines liquid metal droplets to the inner part of a narrow wheel body, and drives the liquid metal movement in the wheel body by applying an external electric field to a skillfully designed follow-up micro-electrode bracket, thereby continuously changing the wheel machine.
