Two-Phase Immersion Cooling for Computing | QD Connectors

Systems Need Info Now!

With more and more information being accumulated, processed and stored digitally, the expectation is that access to the massive amounts of data should be practically instantaneous. Application demands are driving increased deployments of high-performance computers as well as accelerated implementation of cloud and edge computing infrastructures. Data centers professionals are continually asked to provide faster data delivery, better efficiency and increased cost effectiveness in a more sustainable way.

Not Able to Keep Up

Traditional data centers use air cooling methods that are known to be inefficient at dissipating heat. There is a limit to how much cold air can be blown into or how much hot air can be sucked out of racks in a data center facility before needing to space them out. This leads to larger footprints and sidesteps the problem of air cooling inefficiency instead of facing it straight on.

Issues Facing Data Center Professionals

Efficient use of space
More limited optimal locations for large data centers
Pressure for increased use of sustainable technologies
Power usage effectiveness (PUE) goals
Increasing demand for smaller data centers at the Edge
Continued speed of technology innovation

Use CPC Liquid Cooling Quick Disconnects for Two-Phase Immersion Cooling

Collaborating with thermal engineers, system designers and data center operators around the world, CPC is fully engaged in understanding the challenges and requirements of two-phase immersion cooling. We are familiar with the materials and chemistry that thermal management professionals design for, including the various fluids used in 2PLIC and its effects on other components within a system. CPC’s purpose-built Everis^™ quick disconnect couplings and connectors (QDs) portfolio for use in the liquid cooling systems is the result of years of working with thermal management professionals and learning what they require as they design liquid cooling systems for a wide variety of computing environments.

The Larger the Data Center, The Bigger the Need for New Cooling Methods

Exceptionally large data centers, which can occupy hundreds of thousands of acres and can use more than 205 terawatt-hours of electricity, are looking for solutions that provide computing at higher densities and deliver results that:

Enable space reduction
Increase efficiency
Reduce costs
Allow for sustainable operations
Permit future technology innovations

Two-Phase Liquid Immersion Cooling: An Up-and-Coming Solution

Two-phase liquid immersion cooling (2PLIC) is the latest advancement in liquid cooling. Similar to single-phase immersion cooling, electronic components are submerged into a dielectric liquid. However, the immersion fluids used by two-phase liquid cooling are vastly different from those used in single-phase cooling. During two-phase immersion cooling, the immersion fluid absorbs the heat and begins to boil. The fluid then turns into a vapor that rises and condenses on a heat exchanger (condenser) within the immersion tank. The condenser transfers the heat to facility water for waste heat recovery where it can be used as warm water in the facility, for example.

Why Choose Two-Phase Immersion Cooling?

The two-phase immersion cooling fluid is completely contained; there is no loss of any fluid during operation.

Benefits of 2PLIC

Less cooling infrastructure required
Lower―even zero―water usage
Reduced square footage needed
Lower PUE with more energy available for computing
Overall higher efficiencies

"Most 2PLIC systems operate at a full system (not just a mechanical system) PUE of 1.028, meaning less than 3% of energy is used on cooling infrastructure, leaving 97% available for computing."

Getting Ready to Implement

Currently only a few companies are able to implement data center platforms using 2PLIC technology and its associated engineered fluids. IT hardware that supports two-phase immersion cooling is not readily available. However, data center professionals and thermal engineers are educating themselves on the technology and the potential positive impact it could have on their businesses. Once the hardware is readily available, an increasing number of data centers of all sizes may jump on board to take advantage of the benefits of two-phase liquid immersion cooling.
