Raijintek shows passively cooled all-in-one water cooling

Hardware manufacturer Raijintek has shown an all-in-one water cooler that functions as a closed system at Computex in Taiwan. The cooler has no moving parts and functions by heating a liquid that circulates through natural circulation.

The liquid used, of which no further details are known, boils below forty degrees Celsius, making it gaseous. It rises to a heat exchanger and then condenses back to a liquid by cooling, after which the liquid descends again and the process repeats.

TechPowerUp managed to capture photos of the cooler in action on the Computex. To do this, an employee of the Raijintek stand poured boiling water from a kettle into a container that contains the heatsink of the liquid cooling. Then the closed system cooled the tray quickly.

Raijintek would have put a lot of research money in the cooler and now have all patents registered. This would make the product ‘ready for sale’. It is not yet known what the product or a derivative thereof will cost.

It is not the first pumpless water cooling or water cooling with heat exchanger. Various case modding projects with heat exchangers can be found on the internet. SilverStone showed a pumpless water cooling on the Computex two years ago, but it still had a normal radiator. It is not clear whether the latter ever went on sale.
