In the era of computing power, why has the EC fan become the new standard for cooling and a must-have for intelligent computing centers

The training of large models has driven up the demand for computing power, and the power density of individual cabinets in intelligent computing centers has increased, posing higher requirements for cooling. Traditional AC fixed-frequency fans have obvious shortcomings and cannot meet these demands. EC fans, which possess multiple advantages, have now become the core standard for cooling in intelligent computing centers.

1. Optimize PUE for ultimate energy efficiency and reduce total lifecycle costs.

The cooling energy consumption in the intelligent computing center accounts for a high proportion. The EC fan, equipped with a permanent magnet brushless motor, is more energy-efficient than traditional AC fans under the same air volume. It also supports stepless speed regulation, allowing for on-demand speed adjustment to avoid ineffective energy consumption. After deployment, it can stably control the Power Usage Effectiveness (PUE), meeting green and low-carbon requirements. The transformation cost can usually be recovered within 1 to 2 years, with considerable long-term benefits.

II. Global intelligent linkage ensures stable computing power through precise temperature control. 

The business load of the intelligent computing center fluctuates greatly, and temperature control imbalance can easily lead to chip frequency reduction or even business interruption. The EC fan can be connected to a management platform to collect data in real time and adjust air volume to form a closed-loop control. At the same time, it adopts a redundant design, so that if a single fan fails, the other fans can automatically compensate for the air volume. It also has a built-in protection alarm function that predicts wear and tear in advance to avoid the spread of faults. It can also adapt to various cooling devices, covering the needs of the entire chain.

III. Stable and long-lasting operation, low noise and low maintenance investment.

 EC fans have no mechanical brushes, resulting in low friction loss and a lifespan that is 2 to 3 times longer than traditional AC fans, with a longer replacement cycle. Through optimized design, they can adapt to complex working conditions, operate with low vibration and noise, improve the maintenance environment, reduce replacement frequency and failure rate, and reduce annual fan-related labor costs by more than 30%. They are suitable for the mode of intelligent computing centers with fewer personnel on duty and uninterrupted operation.

IV. Flexible adaptation across all scenarios, supporting rapid expansion of computing power. 

The EC fan is compatible with wide-range AC input, eliminating the need for an external frequency converter. This simplifies the design while reducing losses and pressure on associated equipment. With a standardized modular structure, it can be quickly extended to accommodate deployments of different sizes. Both new construction and renovation projects can be quickly installed without the need for large-scale modification of existing facilities, shortening project cycles and adapting to the phased expansion needs of computing power.

Currently, green and low-carbon development stands as the core trend in the computing power industry. Cooling, as a core infrastructure, significantly impacts operational costs and computing power stability. EC fans, leveraging their multi-dimensional advantages, have addressed the challenges of cooling, energy consumption, and operation and maintenance in high-density intelligent computing centers. They have become a widely recognized high-quality cooling solution in the industry, enabling the establishment of a more adaptable cooling system for intelligent computing centers and ensuring the development of AI computing power.
