Сетевое оборудование уменьшается — и нагревается.

По мере того как мы стремимся к более быстрым, плотным и умным коммутаторам, тепловой дизайн стал решающим фактором. Вот почему компактные вентиляторы — когда-то второстепенный элемент — теперь находятся в центре обсуждений надежности и производительности в конструкторских отделах OEM-производителей.

Реальная проблема перегрева

Современные коммутаторы и маршрутизаторы вмещают серьезную производительность в компактные металлические корпуса: многоядерные ASIC, PoE высокой плотности и стекированные оптические порты — все это генерирует значительное тепло. Без эффективного охлаждения производительность снижается, а долгосрочная надежность падает.

Even a 5°C temperature rise can double component failure rates, and that’s why airflow management is not just thermal engineering, but a reliability strategy.

Что делает компактные вентиляторы такими особенными?

Unlike large system fans, compact fans used in switches and routers must operate under strict space, noise, and airflow constraints. The key is high static pressure, which allows air to move through dense heat sinks and PCB layers.

They must also endure 24/7 workloads, which is why materials, motor control, and bearing systems determine how long a network device runs without failure.

At Shenzhen Xinqifeng Technology, engineers design DC, AC, and EC fans specifically for compact environments, balancing airflow efficiency, low noise, and long lifespan, especially vital for 1U and 2U network gear.

Основные типы, которые вы найдете в сетевом оборудовании

In real designs, these fan types often work together. Axial fans handle broad airflow, while blowers target hotspots. Knowing which to use helps you balance cooling efficiency, noise, and cost.

Smarter Cooling = Less Noise, More Efficiency

Adaptive control is now standard. PWM (Pulse Width Modulation) and temperature sensors let fans automatically adjust their speed to reduce both energy use and noise.

For office-edge networking devices, it means quieter operation. But for data centers, it means lower total cost of ownership and easier predictive maintenance.

A Real Engineering Example

A one of our client developing a 1U switch (around 220 W) faced overheating near the ASIC region. But by upgrading from our axial fans to a mini centrifugal fan with 30% higher static pressure, and adding a simple airflow guide, the result was impressive:

• ASIC temperature dropped by 10°C,
• noise level reduced by 5 dBA,
• Overall reliability improved notably.

That’s the power of precise airflow design and the right fan integration — often, small changes yield major stability improvements.

Что проверить перед выбором вентилятора

• Airflow (CFM): actual air volume moved
• Static Pressure (mmH₂O): critical for tight airflow paths
• Noise (dBA): aim below 40 dBA for office gear
• Подшипниковая система: dual ball bearings for longer life
• Voltage & Connector Type: 12V/24V, 3-pin or 4-pin (PWM/tach)
• Rated Lifetime: 50,000–70,000 hours ensures long-term uptime

Even minor spec upgrades (or a fan with slightly higher pressure) can lower hotspot temperatures by several degrees, extending the life of key components.

Будущее охлаждения

As network devices evolve, so do their cooling systems. It may be expected to see:

• EC mini-blowers replacing traditional fans for efficiency
• AI-driven predictive fan control
• Hybrid cooling using vapor chambers + fans
• Modular hot-swap designs for zero downtime

Подведение итогов

Compact fans may be small, but they define uptime, reliability, and user comfort. Designing them in early — not as an afterthought — ensures your networking gear performs consistently and quietly.
