Critical challenges of data center cooling

Increased power density and heat generation

Technological progress leads to denser, more powerful equipment, generating significant heat. Traditional cooling systems often fail to cope, resulting in inefficiencies, hotspots, and potential equipment failure. Boyd leverages advanced thermoforming and efficient product design technology to create baffles that fit perfectly within data center systems and enhance airflow efficiency while directing cool air to critical components. Boyd’s FR V-0 grade polypropylene air baffles are flame-resistant, durable, lightweight and efficient to manufacture or fabricate, making them an excellent alternative to metal partitions, especially in tight server rack spaces.

Electrical safety risks

Densely packed high-power components elevate the risk of electrical shorts and fires, threatening equipment damage, safety hazards and increased downtime. Boyd’s air baffles are made of flame-rated electrically insulating material. These specialized materials minimize the risk of electrical shorts and fires, ensuring the safety of both equipment and data center personnel. They also use high dielectric constant materials, such as polypropylene and polycarbonate, to insulate sensitive components from harmful electrical interactions and prevent shorts.

Optimizing airflow

Boyd’s thermoformed or assembled baffles guide cool air to server inlets and manage hot air expulsion paths, preventing recirculation, eliminating hotspots and maintaining uniform temperatures. These solutions include air blocking, shielding, gasket and diverter materials designed to prevent air leakage and ensure optimal airflow patterns within the data center.

Environmental concerns and energy costs

As major electricity consumers, primarily for cooling, data centers face pressure to reduce energy use and environmental impact. Boyd’s solutions include air blocking, shielding, gasket and diverter materials optimized for sealing force and compression force deflection to maximize cool air use in an enclosure. Boyd’s high-performance polyimide foam SOLIMIDE, nitrile, EPDM, polyurethane and silicone foams prevent air leakage and optimize airflow, enabling data center cooling systems to operate at peak performance and optimize energy demand and costs.

Maintaining consistent cooling in evolving systems

Data centers constantly evolve, with new components disrupting cooling patterns. Flexible, adaptable cooling solutions are essential to address these changes. Boyd’s baffles and CPU shrouds focus cooling on high-heat components like CPUs and memory modules, preventing overheating and boosting system reliability and performance.

Understanding baffles: The key to optimized airflow

Baffles play a critical role in data center cooling by optimizing airflow efficiency. These solutions strategically control airflow, improving cooling by directing cool air precisely and expelling hot air effectively. Used inside servers, within racks or externally, baffles transform chaotic air movement into structured flow, crucial for thermal management. When implemented properly, they prevent hotspots, reduce cooling energy use and balance the thermal environment to maintain data center reliability and safety.

Key functions of baffles

1. Forcing front-to-back airflow: Baffles direct cool air through server fronts and direct hot air from the back, preventing hot and cool air from mixing and ensuring all critical components receive efficient cooling.

2. Managing air paths: They guide cool air to server inlets and manage hot air expulsion paths, preventing recirculation, eliminating hot spots and maintaining uniform temperatures.

3. Minimizing air loss: By sealing gaps and directing airflow efficiently, baffles reduce cool air loss, crucial to lower energy consumption and improve cooling system efficiency.

4. Reducing hot spots and recirculation: Baffles optimize airflow patterns to prevent hot spots, reducing the need for cooling systems to work excessively and enhancing energy efficiency.
