Introduction: Increasing Data Center Cooling Demands
The exponential rise of Artificial Intelligence (AI), machine learning, and high-performance computing (HPC) is fundamentally reshaping the data center landscape. Modern processors, such as high-core count CPUs (Central Processing Units) and powerful GPUs (Graphics Processing Units), now exceed power densities that traditional air-cooling can manage efficiently. The resulting challenges include prohibitive energy costs and failure to meet ever-growing cooling requirements.
At Coolnet, we recognize that the future of the data center relies on moving the heat transfer medium closer to the source. Our integrated approach to liquid cooling, which includes solutions managed by the Coolnet High-Performance CDU (System Controller), offers a critical path to sustainable, high-density operations. This system, integral to the cold plate data center methodology, maximizes efficiency and protects high-value IT assets.
The Working Principle and Advantages of Cold Plate Cooling in Data Centers
Cold plate cooling data center systems are a form of direct-to-chip liquid cooling. The core component managing this process is the Coolant Distribution Unit (CDU).
Working Principle
Direct Contact: A specialized cold plate is clamped onto the heat-generating processor (CPU or GPU).
Heat Transfer: Liquid coolant flows through micro-channels within the cold plate, instantaneously transferring heat from the chip into the liquid.
Removal & Control: The heated liquid is pumped out of the server rack and managed by the featured product, the Coolnet High-Performance CDU. The CDU manages the flow, pressure, and temperature of the coolant.
Product Feature Spotlight: Coolnet High-Performance CDU
The Coolnet High-Performance CDU is defined by its core functional features, ensuring maximum system integrity and adaptability:
Integrated System Monitoring: The CDU provides precise, real-time monitoring and control of the entire liquid cooling loop.
High-Efficiency Heat Exchange: The design employs an efficient plate heat exchanger to manage thermal transfer between the primary and secondary loops.
Leak Detection and Management: The system is equipped with advanced safety features, including real-time water leakage detection and monitoring of environmental conditions within the server rack.
Redundant Components: Key components within the CDU are designed with redundancy, ensuring high system stability and continuous operation even during component maintenance or failure.
Adaptability: The CDU features flexible interface options that allow for seamless integration with different types of heat rejection units (like dry coolers or chillers).
Comparison of Cold Plate Liquid Cooling and Traditional Cooling Methods
The shift to cold plate cooling data center solutions represents a fundamental change in heat management strategy when compared to traditional air cooling.
Heat Transfer: Liquid is far more effective at absorbing and transporting heat than air. This allows the system to support ultra-high density racks, unlike air cooling which struggles to dissipate localized heat efficiently.
Energy Consumption: Compared to air cooling, systems controlled by the Coolnet CDU dramatically slash the power required for cooling by reducing the workload on CRAC (Computer Room Air Conditioner) units. The resulting efficiency contributes to a significant reduction in the facility’s overall PUE (Power Usage Effectiveness).
Waste Heat Potential: The system is designed to provide high-grade waste heat that can be reused for auxiliary purposes, delivering added thermal economy that air cooling cannot match.
The cold plate data center approach, managed by a precise CDU, is known for its minimal footprint, making it ideal for maximizing valuable floor space in modern facilities.
Improving the Stability of High-Performance Equipment with Cold Plate Cooling
For applications like large language models and scientific simulations, the stability of the compute hardware is paramount. High-performance CPUs and GPUs are engineered to operate at maximum efficiency when junction temperatures are tightly controlled.
The superior thermal control offered by a Coolnet system, specifically managed by the High-Performance CDU, directly contributes to equipment stability and longevity:
Elimination of Hot Spots: Cold plates provide uniform cooling across the chip’s surface, eliminating the detrimental temperature variations caused by restricted airflow that can trigger thermal throttling or premature failure.
Consistent Thermal Headroom: The CDU maintains consistent thermal headroom by precisely controlling coolant flow and pressure, ensuring stable operating temperatures for the processors.
Operational Guarantee: We stand by the engineering of our in-house manufactured liquid cooling components, including the High-Performance CDU, backing with a dedicated one-to-two- year product quality guarantee.
