Cost Effective

Chilldyne’s negative pressure failure tolerant system is what allows the benefits of liquid cooling to be realized

There are highly reliable liquid cooling systems that use aerospace quality fitting and high-pressure hoses. These are too expensive for most users. These systems normally run at 20 psi, but they are designed to withstand 300 psi. The reason for this is water hammer, where if someone shuts off a valve or disconnects a shut off connector on a running system with a long piping run, the momentum of the coolant can turn into a pressure spike.
Negative pressure systems don’t create these kind of pressure spikes because the tubing used is very resilient and the coolant during startup has many bubbles in it. Also, the racks don’t use shut off connectors. The Chilldyne system lets air into the coolant system when it shuts down, so that when it restarts there are no worries about water hammer.

Thermal Resistance vs. Mass Flow Rate:

Today, thermal engineers are working to close the gap between the current air-cooled heat sink technology and the theoretical ideal air–cooled heat sink. At Chilldyne, we have already closed this gap and much more. Because our liquid cooling technology is significantly more efficient than air, our focus is on lowering the cost of the overall system.

Inexpensive Connectors

Because the Cool-Flo system operates under negative pressure, the system does not require expensive, pressure-tested connections.

Low Cost, High Volume

The Cool-Flo system utilizes low cost silicone/urethane tubing and low-tech connections, minimizing cost for high volume use.

Low Maintenance

Chilldyne’s patented pistonless pump contains no moving parts, reducing maintenance costs.

Ancillary Cooling

The modified, finned heat sinks act as a free “rear-door heat exchanger” for the rest of the data center, so the entire server gains the benefit of ancillary cooling of components even though they are not directly liquid cooled.

Return on Investment

The return on investment in Chilldyne’s Cool-Flo system will vary, depending on the current operating characteristics of the data center such as PUE and the cost of power. A 1-2 year payback on Cool-Flo System is possible.
