Thermal Management in Data Centers: Rear Door Cooler, Rack Cooler and Direct to Chip Liquid Cooling


Data centers are the lifeblood of today’s digital world. These facilities, which house critical electronic equipment, are vital to their uninterrupted operation. Therefore, it is vital that the data center environment is kept at the appropriate temperature.


High heat can shorten the lifespan of electronic equipment, degrade performance, and even cause failures. Therefore, data center operators must use a variety of thermal management strategies to effectively manage heat.


Thermal Management Strategies:

  • Rear Door Cooler: Rear door coolers are used to remove heat generated from servers out of the data center. This prevents hot air pockets from forming and helps reduce the overall data center temperature.


  • Rack Cooler: Rack coolers are devices placed between racks that directly cool the heat generated from servers. This helps eliminate hot spots and increase cooling efficiency.


  • Direct to Chip Liquid Cooling (Cold Plates)

    DTC liquid cooling is one of the latest and most advanced data center thermal management technologies. In this system, the coolant is directly contacted with the surface of the processor (CPU) or other electronic components. This provides higher heat transfer efficiency and lower temperatures compared to traditional liquid cooling systems.

    Some key advantages of DTC liquid cooling are:



    • High Cooling Capacity: DTC liquid cooling offers much higher cooling capacity than traditional air and liquid cooling systems. This allows data centers to accommodate higher density servers and other electronic equipment.


    • Energy Efficiency: DTC liquid cooling uses significantly less energy than traditional air cooling systems, helping to lower data center operating costs.


    • Noise Level: DTC liquid cooling systems are quieter than traditional air cooling systems, making them ideal for installing data centers close to office buildings or residential areas.


    • Humidity Control: DTC liquid cooling prevents damage to electronic equipment by maintaining lower humidity levels compared to air cooling systems.



      DTC liquid cooling is a powerful tool for optimizing thermal management in data centers. It offers many advantages such as high cooling capacity, energy efficiency and low noise level. However, it also has some disadvantages such as installation cost, complexity and risk of leakage.

      To determine whether a DTC liquid cooling system is suitable for your data center, a comprehensive evaluation should be performed and support should be sought from thermal experts in selecting equipment that will eliminate the disadvantages.


Which Strategy to Choose?

The optimal thermal management strategy for a data center depends on the specific needs and priorities of the data center. Some factors include:


  • Data center density: Higher density data centers generate more heat and require higher cooling capacity.


  • Budget: DTC liquid cooling systems are more expensive than traditional air and liquid cooling systems.


  • Complexity: DTC liquid cooling systems are more difficult to install and maintain.


  • Noise level: Rear door coolers and rack coolers are noisier than DTC liquid cooling systems.


  • Humidity control: DTC liquid cooling prevents damage to electronic equipment by maintaining lower humidity levels compared to air cooling systems.


Data center thermal management is a complex topic, and no single solution can meet all needs. Combining different strategies, such as rear door coolers, rack coolers, and DTC liquid cooling, is the most effective way to ensure that the data center environment is kept at the appropriate temperature.


We are here to support you in conducting a comprehensive assessment to determine the most appropriate thermal management strategy for your data center.
