ZTE makes splash with server immersion cooling demonstration

by josh perry, editor


according to an article from anandtech.com, wireless company zte made waves at the recent mobile world congress in barcelona, spain with a demonstration of its immersion cooling solution for servers, which was focused on dense computing applications.


zte’s immersion cooling solution was on display at the mobile world congress.


“i was told that due to the design, fiber network connections do not work properly when immersed: the distortion created by the liquid even when a cable is in place causes a higher than acceptable error rate, so most connections are copper which is not affected,” senior editor ian cutress wrote. “i was told that they do not have a problem with the thermal capacity of the liquid, and supporting the next generation of cpus would be no problem.”


zte is working with a chinese company to produce an enhanced liquid that can be used in the system at a lower cost point for consumers.


the article added, “of course, the downside to an immersion setup is the ability to repair and upgrade. if possible, the owner does not want to have to go in and replace a part. it ends up messy and potentially damaging, or requires a full set of servers to be powered down. there is ultimately no way around this, and while the issue exists with standard data center water cooling, it is a more significant issue here.”


zte acknowledged the issue and said that this system was for edge computing systems that could be working for five years or longer.
