Asetek, a San Jose, California-based provider of sealed liquid cooling solutions for personal computers has launched versions of its product for servers and for data center racks that will cool them using warm water.

In June, the company reported having shipped its one-millionth liquid cooler for a PC and having been granted three technology patents. Both developments have emboldened the company to make the push into the data center market.

Andre Eriksen, founder and CEO of Asetek, said surpassing the one-million-unit mark testified that customers recognized quality and performance of the company’s product.

“Coincidentally, we were just granted 3 US patents covering our solutions,” he said. “This gives us a perfect stepping stone for protecting our intellectual property as we move forward into new markets such as server and data centers.”

The solution for servers and PCs delivers cooling liquid directly to the CPU. If used in servers, it eliminates the need for computer room air conditioners, Asetek said on its website.

The new hot-water liquid-cooling RackCDU solution for data centers is a rack-level cooling-distribution unit mounted on top of a rack. It includes three additional power distribution units and direct-to-chip cooling loops for each server within the rack.

The cooling loops are drop-in replacements for existing server heat sinks. This means customers can retrofit existing data centers with RackCDU during server refresh cycles.

The system has two loops: a server one and a facilities one, separated by liquid-to-liquid heat exchangers. Cooling liquid is delivered to each server by redundant hot-swappable pumps.

Asetek says an immediate-to-one-year payback cycle is typical with Rack CDU.
