I. Four Core Pain Points of Communication Base Station Heat Dissipation

Pain Point 1: The requirement for high reliability of base station equipment operating continuously 24/7

Phenomenon:Communication base stations operate continuously year-round, and insufficient fan lifespan can cause equipment downtime.

root cause:Inexpensive oil-bearing fans have a lifespan of only 10,000 to 20,000 hours, far below the design lifespan of a base station.

Industry data:The base station is designed for a lifespan of 10-15 years, and the fan must be maintenance-free for 5-7 years.

Pain Point 2: Outdoor base stations require wide temperature range and dust and water resistance.

Phenomenon:In northern winters, the fan fails to start at -40℃, and shuts down in summer when outdoor temperatures reach +65℃; in southern regions, it gets wet and dusty during the rainy season.

root cause:The fan is not designed for wide temperature range and lacks IP protection.

Industry Standards:Outdoor base station equipment must meet the operating temperature requirements of -40℃ to +65℃ and IP55/IP65 protection.

Pain Point 3: Base Station Energy Consumption Requirements for Low Power Consumption

Phenomenon:Base station electricity costs are one of the main operating costs for operators, and the power consumption of fans cannot be ignored.

root cause:Ordinary fans are inefficient and consume a lot of power.

Industry data:The annual electricity cost of a 5G base station is about 20,000 to 30,000 yuan, so energy saving of fans is meaningful.

Pain Point 4: Heat Dissipation Challenges Arising from the High Power Consumption of 5G AAU

Phenomenon:The power consumption of 5G AAU devices is 3-4 times that of 4G RRU, resulting in a significant increase in heat dissipation requirements.

root cause:AAU has high integration, high power consumption (1000-1500W), and is difficult to design for heat dissipation.

Industry data:5G AAU needs to adopt a high-efficiency cooling fan + heat sink solution.

V. Frequently Asked Questions (FAQ)

Q1: What are the difficulties in heat dissipation for 5G AAU compared to 4G RRU?

A: The power consumption of 5G AAU is 3-4 times that of 4G RRU (1000-1500W), but the size is similar. The heat dissipation density is greatly improved, requiring a more efficient heat dissipation solution.

Q2: What protection level is required for outdoor base station fans?

A: At least IP55, IP65 is recommended. The Fengheng IP65 series is dustproof and water-resistant, suitable for outdoor environments.

Q3: How long can the fan of a communication base station typically last?

A: Original factory fans typically last 3-5 years. WindConst dual ball bearing fans can last 7-10 years.

Q4: What should I do if the base station fan fails to start in low-temperature environments in northern regions?

A: Select a wide-temperature range model (-40℃~+85℃) and use a special low-temperature lubricating oil. The Fengheng wide-temperature series can meet this requirement.

Q5: Does it support fan failure detection?

A: Yes. Customizable fans with FG (speed feedback) and RD (fault alarm) signal outputs are available for real-time monitoring by base station monitoring systems.

Q6: Do you support sample testing?

A: Free sample testing is available. We can provide original fan specifications and help you find the right upgrade solution.
