Data centers contain high -performance computing equipment that generates large heat.
Refreshing in data centers removes heat from servers and other devices to keep them efficiently. This is achieved by circulating cold or liquid air around the device while redireing hot air or hot liquid away. Without cooling, excessive accumulation of heat can cause system failure, slow performance, and shortening the life of critical ingredients.
Her servers generate more heat as data centers processing more data and running more applications. To prevent high temperature and maintain the operation of systems smoothly, they need effective cooling methods to remove excess heat and maintain safe temperatures.
The type of cooling system directly affects the choice of energy and data cables. The correct cables should be chosen based on temperature resistance, exposure to moisture, EMI shield, and flexibility for installation. In this article, we show the different types of cooling systems in data centers and cables associated with these cooling systems.
Data center cooling systems
Cooling methods can be widely classified into air -based, liquid, hybrid cooling solutions. Each has different effects on choosing cables, costs, efficiency and best cases. Below, we all explain to them.
Air -based cooling systems
The air -based systems depend on managing the air flow to waste heat.
There are different types of air -based cooling in data centers:
CRAC (Air Conditioning Computer Chamber) and CRH
CRAC units use coolers and compressors, while CRAH uses water and refrigerated fans.
Best for: Traditional institution data centers and polluted facilities.
It costs: Moderate to high, depending on the infrastructure.
efficiency: Less than liquid cooling because air has a lower temperature capacity, but is widely used.
flaws: Heavy energy, less effective for high -density work burdens as this type of air cooling will face heat removal in high -density environments.
Contains the hot corridor/cold corridor
This type of air -based system is separated by hot and cold air flows to improve efficiency compared to simple air -based systems.
Best for: Foundation data centers on a large scale, cloud computing data centers.
It costs: Moderate initial investment, but saving energy over time.
efficiency: It improves air -browned settings but still requires additional cooling.
flaws: The exact air flow management requires: supplementary cooling sources to generate cold air.
Row
This type of air -based system places cooling units between or inside the server shelves.
Best for: High -density data centers, bonds.
It costs: High costs provided, low operating expenses.
efficiency: Very effective for targeted cooling.
flaws: It requires careful planning and complementarity. For the best effectiveness, you should put it based on the thermal pregnancy.
Liquid -based cooling systems
Liquid cooling systems provide higher efficiency and are ideal for high -density environments. This is because fluids absorb and transport heat faster than air, allowing better thermal management and low energy consumption.
Fabricated water systems
This type of liquid refrigeration system is used a central cooler to supply cold water with CRH units.
Best for: Large institution data centers and pollinated facilities.
It costs: High due to infrastructure requirements.
efficiency: Power is more efficient than air cooling.
flaws: It requires plumbing and cooling towers.
Liquid cooling directly into a chip
This liquid cooling rotates directly into the ingredients of heat generation.
Best for: HPC and data centers driven by artificial intelligence.
It costs: High but meet it by improving performance.
efficiency: Very high, ideal for compact and high -energy work burdens.
flaws: It requires custom devices and integration.
Reading indulgence
This liquid cooling immerses servers in a heat -absorbing insulating liquid.
Best for: High data centers, Blockchain mining, and high -density artificial intelligence computing.
It costs: Highly high investment, but long -term savings.
efficiency: One of the most efficient cooling methods available.
flaws: It requires specialized equipment and reintegration of the server.
Hybrid cooling solutions
These solutions combine air and liquid cooling to improve efficiency. By combining these elements, it remains equally beneficial to each of the high -density and low -density environments.
Cooling is evaporation
This type of solution uses water evaporation to reduce temperatures. This reduces dependence on mechanical cooling.
Best for Large cloud data centers and cost -sensitive operations.
It costs: Moderate, with a possible saving energy.
efficiency: Top of traditional air cooling.
flaws: This depends on the conditions of the climate because it depends on the evaporation of the water to cool the air.
Adiabatic cooling
It enhances flying cooling with controlled water.
Best for: Sustainable data centers, areas with water restrictions.
It costs: Moderate, but it reduces water consumption.
efficiency: More efficient than basic evaporative cooling.
flaws: It requires monitoring levels of moisture.
Earth thermal cooling
It enhances underground water sources for heat exchange.
Best for Green data centers and terrestrial thermal resources.
It costs: The high cost of installation but low operating expenses.
efficiency: Very effective for long -term use.
flaws: Limited by site. The water that can be drilled should be available.
Choose cables suitable for data center cooling systems
The type of cooling system affects the choice of energy transmission and data transfer. Cables should be chosen based on many factors: bearing temperature, moisture resistance, protection from electromagnetic interference (EMI), and the elasticity of guidance to ensure the reliability of the data and efficiency center. Here is our guide on how to choose them correctly:
Energy cables
Thhn Cuble, heat -resistant, costly effective, and used in air cooler systems. It is not ideal for wet environments due to the absorption of nylon coating.
Xhw-2 Water resistance, low insulation loss, suitable for liquid refrigerated environments. Less flexible compared to the THN, which makes guidance in tight spaces more difficult. However, it is often chosen based on water resistance properties.
MC (Met Mat) cable Protected, solid, reduces EMI in hybrid cooling settings. The heavier than standard power cables, which require strong support structures. In general, it is excellent for high areas of EMI in mixed cooling systems.
Stair cable (TC-AR, TC-AR-JP) -Gennate, back flame, supports upper guidance in wet conditions. Not suitable for direct burial or submerged applications. It is used in various public settings operations regardless of the type of cooling.
Saoo/Siu -Drinch, antipyretic, and wonderful to cool in row and dizziness. Note that it is larger and more expensive than THN or stairs.
Data cables
CAT 6A (STP) -Coast, 10 GB per second, ideal for high areas of EMI refrigerated with air.
Cat 7 / Cat 8 Additional shielding, treats up to 40 GB per second, the best for liquid high -density shelves. It can be harsh and difficult to direct, exaggerated in low -speed applications.
Visual fiber cables – Emi is fortified, ideal for all cooling systems, the best for indulging cooling.
Special considerations for indulging cooling
Cooling indulgence requires cables that carry the constant purpose in the buffer cooling fluid. Here is what is required to cool down indulging:
Cables should resist insulating fluid absorption.
Fiber optics are perfect because they are not described and fortified from EMI.
Types of Energy cable insulation:
Teflon (PTFE), XLPE, FEP, EPR, Silicon rubber Various levels of moisture and heat resistance.
The attached liquid conductors can prevent fluid entry, ensuring long -term performance.
The themustic cover provides additional durability in the submerged environments.
conclusion
The choice of the appropriate cooling system ensures stable performance and energy efficiency in the data center. Cables must be identified based on cooling conditions to support reliable energy distribution and data transfer. In high -density or refrigerated settings with liquid, the heat -resistant cables and moisture resistant to failure and ensure durability in the long term. In low -density areas or bridges with air, flexible and lightweight cables such as THN or stairs are the best bet.
