Data Centers & Thermal Cooling Systems

When writing this article, data centers are rapidly spreading throughout the globe. In the past, data centers were mainly used by large firms and organizations for processing and storing data. Nowadays, since the advent of the public cloud system, data centers, and their uses have expanded their uses. From hosting e-commerce transactions to powering online gaming platforms and AI learning systems.



With the increase in the number of data centers, the cooling challenges of maintaining these devices have also increased in complexity. Depending on the use, data centers are now required to be bigger, warmer, taller, dryer, and more flexible. Data centers build in massive cities such as Tokyo, or Hongkong, have to accommodate its surrounding by reducing their width while increasing their height. Thermal management providers are then needed to adjust their cooling systems to fit with these narrower dimensions. So with these challenges, each data center requires its own specialized thermal solution that can fit well with its thermal environment. Another major issue with cooling data centers is energy consumption. Much of the power loss when running data centers tends to come from temperature management systems. Providing an energy-saving option should be a major concern for these thermal management providers.


Considering these issues, better and more innovative thermal solutions have to be made. The most common cooling solution used in data centers is often water cooling whereby the water is chilled and flown throughout the heat spot of the device. To build upon the water cooling solution, we propose a combination of water cooling and air cooling technologies to better meet the thermal needs. Integrating the cooling combination can be creatively done within your desired CRAC unit. The reasons for this proposition are listed below:


Cost

Water cooling by itself tends to add significant costs to data center manufacturers and the client hosting these centers. The initial manufacturing cost of water cooling comes in terms of its many intricate parts and the chiller. These parts tend to be the bulk of the cost however, the cost of maintaining them and keeping them running regularly is also quite significant. That is in terms of electric power and water consumption. With the combination of air cooling by vapor chamber and water cooling, we're able to reduce the amount of water needed to pump throughout the system as the vapor chamber will have direct contact with the heat source. This direct contact enables heat to flow through the VC and towards a water source. Thus, not needing water to be pumped into the heat source. With this, we can reduce the amount of water needed and therefore, reduce the total cost spent on running. By combining both air cooling and water cooling, we suggest using our loop thermosiphon technology which is able to draw from different heat sources. The loop thermosiphon is also flexible in design as the shape can be molded into a wide variety of designs to best fit the CRAC unit of the server.


Risk of Leakage:

When using water with any kind of electronic device at proximity, the issue of leakage will always be a major concern. Water cooling system providers have definitely come up with excellent ways of reducing the likelihood of leakage occurring. However, the effort, cost, and time spent on preventing this issue aren't always the best thing. We can reduce the need to be concerned about leakage by using a hybrid system (air + water cooling). Parts such as CPUs and GPUs can be more effectively cooled with the vapor chamber without being concerned with water leaking on these components. The vapor chamber can then transfer the heat towards a water source away from these components for the heat to be directed outside of the device. With a hardware component as a medium for heat exchange rather than water, you can prevent unnecessary leakage and spend less time thinking of preventative measures. With less time spent on preventative measures, you can invest more time in the efficiency and performance of the server system.


Water cooling has been a great solution for data centers at managing high temperatures where air cooling is insufficient in certain areas. However, as the technology develops, the thermal environment becomes more complex and challenging, thus, requiring us to come up with newer, more innovative thermal solutions. Combinations of water and air cooling are just one of the many innovative solutions you'll be able to use by working with us.
