\n

I. Four Core Pain Points of Communication Base Station Heat Dissipation<\/h2>\n

Pain Point 1: The requirement for high reliability of base station equipment operating continuously 24\/7<\/h3>\n

Phenomenon:<\/strong>Communication base stations operate continuously year-round, and insufficient fan lifespan can cause equipment downtime.<\/p>\n

root cause:<\/strong>Inexpensive oil-bearing fans have a lifespan of only 10,000 to 20,000 hours, far below the design lifespan of a base station.<\/p>\n

Industry data:<\/strong>The base station is designed for a lifespan of 10-15 years, and the fan must be maintenance-free for 5-7 years.<\/p>\n

Pain Point 2: Outdoor base stations require wide temperature range and dust and water resistance.<\/h3>\n

Phenomenon:<\/strong>In northern winters, the fan fails to start at -40\u2103, and shuts down in summer when outdoor temperatures reach +65\u2103; in southern regions, it gets wet and dusty during the rainy season.<\/p>\n

root cause:<\/strong>The fan is not designed for wide temperature range and lacks IP protection.<\/p>\n

Industry Standards:<\/strong>Outdoor base station equipment must meet the operating temperature requirements of -40\u2103 to +65\u2103 and IP55\/IP65 protection.<\/p>\n

Pain Point 3: Base Station Energy Consumption Requirements for Low Power Consumption<\/h3>\n

Phenomenon:<\/strong>Base station electricity costs are one of the main operating costs for operators, and the power consumption of fans cannot be ignored.<\/p>\n

root cause:<\/strong>Ordinary fans are inefficient and consume a lot of power.<\/p>\n

Industry data:<\/strong>The annual electricity cost of a 5G base station is about 20,000 to 30,000 yuan, so energy saving of fans is meaningful.<\/p>\n

Pain Point 4: Heat Dissipation Challenges Arising from the High Power Consumption of 5G AAU<\/h3>\n

Phenomenon:<\/strong>The power consumption of 5G AAU devices is 3-4 times that of 4G RRU, resulting in a significant increase in heat dissipation requirements.<\/p>\n

root cause:<\/strong>AAU has high integration, high power consumption (1000-1500W), and is difficult to design for heat dissipation.<\/p>\n

Industry data:<\/strong>5G AAU needs to adopt a high-efficiency cooling fan + heat sink solution.<\/p>\n

        V. Frequently Asked Questions (FAQ)<\/h2>\n

        Q1: What are the difficulties in heat dissipation for 5G AAU compared to 4G RRU?<\/h3>\n

        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.<\/p>\n

        Q2: What protection level is required for outdoor base station fans?<\/h3>\n

        A: At least IP55, IP65 is recommended. The Fengheng IP65 series is dustproof and water-resistant, suitable for outdoor environments.<\/p>\n

        Q3: How long can the fan of a communication base station typically last?<\/h3>\n

        A: Original factory fans typically last 3-5 years. WindConst dual ball bearing fans can last 7-10 years.<\/p>\n

        Q4: What should I do if the base station fan fails to start in low-temperature environments in northern regions?<\/h3>\n

        A: Select a wide-temperature range model (-40\u2103~+85\u2103) and use a special low-temperature lubricating oil. The Fengheng wide-temperature series can meet this requirement.<\/p>\n

        Q5: Does it support fan failure detection?<\/h3>\n

        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.<\/p>\n

        Q6: Do you support sample testing?<\/h3>\n

        A: Free sample testing is available. We can provide original fan specifications and help you find the right upgrade solution.<\/p>\n
