Chinese scientists have unveiled a cooling technology that can plunge a liquid cooling medium from room temperature to sub-zero levels in less than half a minute.
This leap in thermal engineering offered a promising heat management solution for energy-hungry data centres that were mushrooming across China and the United States, they said.
By harnessing the unique behaviour of ammonium thiocyanate in water under pressure, the team created a liquid cooling system that mimics squeezing a “wet sponge” – when releasing pressure, it triggers rapid redissolution of salt, absorbing massive amounts of heat almost instantly.

In experiments, a saturated solution cooled by 30 degrees Celsius (54 Fahrenheit) within seconds at room temperature, and in hotter environments, the drop exceeded 50 degrees.
This ultra-fast, high-capacity cooling cycle could transform how artificial intelligence (AI) infrastructure manages heat.
