Cold-Plate Liquid Cooling

While developing advanced cooling technology, compatibility is definitely something to consider. How do we improve cooling efficiency without making extensive changes to existing data centers? Wiwynn presents – Cold-Plate Liquid Cooling Technology


Advanced Cooling Technology:

A seamless upgrade option

Improving Cooling Performance Keeping Existing Data Center Infrastructure


Increased Performance in Every Aspect

Power Density
Tank-based two-phase immersion cooling requires no fans, the component deployment can be a lot closer, and heat dissipation is much faster from phase change of fluid. Cooling capability is therefore much better compare to air cooling to achieve higher power density.

Tank-based two-phase immersion cooling requires no extra power usage from fans and much less from air condition. This form of cooling is therefore much more power efficient compare to air cooling, where the majority of cooling energy expenditure in a data center comes from fans and air condition.

IT Gear Stability
Tank-based two-phase immersion cooling uses boiling liquid, and the liquid boils and transitions at a constant temperature. On the other hand, air cooling is affected by humidity, dust and other external environmental factors, which is in a more unstable environment compare to tank-based two-phase immersion cooling.

Easy Maintenance
Maintaining tank-based two-phase immersion cooling is a simple matter of removing the boards from the tank, taking away the time to drain the liquid as opposed to the maintenance of single-phase immersion cooling. Comparatively, air cooling solution maintenance is slightly more straight forward.

IT operations under normal circumstances will provide a degree of vibration and noise, which will potentially affect the processors, hard drives, etc. For severe cases, they may also lower the system’s lifespan. In tank-based two-phase immersion cooling, the system is immersed in the liquid that greatly alleviates the impact of vibration and noise.

Operation Safety
Operators working on tank-based two-phase immersion cooling will need to wear gloves for safety as the inert liquid is kept at 50 degrees Celsius. On top of that, a good tank management system can also ensure the safety of the operator(s).

How Wiwynn’s Cold-Plate Solution Works?

On the rack of each cold-plate server are two quick connectors (an inlet and an outlet). The cooling liquid enters the rack at its inlet and is directed to the cold plates. The cold plates are stationed at the processors (where most heat are generated) and other heat sources. The liquid heats up during the course and ultimately leaves the rack at the outlet.

When the liquid leaves the server, it is directed to the heat exchanger on the rear door of the rack. The fan wall operates to cool the liquid and a pump drives the cooled liquid back into the rack server for another full cycle of the heat exchange.

Wiwynn’s cold-plate cooling technology expands into multiple liquid cooling solutions. We can use water as the cooling liquid for one possible solution. Dielectric fluid can also be used for 2-phase design solutions. This allows us to take a step further into improving processing density as well as data centers’ safety requirements.

Multiple Innovative Design

Live-Monitored Fan Wall System & Smart Water Pump (iRPU)




Wiwynn’s cold-plate design includes a fan wall for cooling the liquid. Data centers can easily implement this design without needing to change the infrastructure (e.g. hot aisle), allowing for quick and massive deployment into existing data centers.

Wiwynn’s smart RPU can monitor the liquid’s flow rate and fan speed. This dynamically adjusts cooling power usage to optimize power efficiency. On top of that, the fans have their individual on/off switch, where you can individually turn one fan off and replace it without affecting the operations of the remaining fans.

Patented Blind-Mate Connector



Optimized Air Resistant Design



Wiwynn utilizes many exclusive design to ensure operation safety and cooling efficiency. The reliable blind-mate connector provides maintenance as easy as seen in an air cooling server. The floating design gives even more fault-tolerance, allowing simple and easy replacement.

Manifold tube routing design is also optimized for air flow. The pipes connecting the server has their curve minimized to lower the air resistance, which improves air flow while lowering power usage.

System BMC Highly Integrated to the Rack
Comprehensive Drip Detection


Wiwynn’s detection integrated the server’s BMC with the rack (implemented with multiple sensors). The integration allows for the monitoring of pipes and connectors, and for the dynamic adjustment of liquid flow. Moreover, there is also an automatic circuit breaker mechanism to prevent accidents.
