In-vehicle communication heat dissipation solution | Fengheng Technology
Fengheng Technology provides professional heat dissipation solutions for the automotive communication industry. Its products are widely used in in-vehicle T-BOX, in-vehicle infotainment systems, in-vehicle navigation hosts, in-vehicle DVRs, in-vehicle wireless charging, in-vehicle routers, in-vehicle gateways, and vehicle networking terminals, meeting the stringent requirements of the automotive environment for vibration resistance, wide-temperature operation, and high reliability.
I. Four Core Pain Points of Vehicle Communication Heat Dissipation
Pain Point 1: The High Vibration of the Vehicle Environment Tests the Fan
Phenomenon:The vehicle vibrated continuously while in motion, causing damage to the fan bearing and breakage of the fan blades.
root cause:The fan structure is not strong enough and lacks anti-vibration design.
Industry Standards:Vehicle-mounted equipment must meet the ISO 16750-3 vibration test standard.
Pain Point 2: The Reliability Requirements of Fans in Wide Temperature Environments
Phenomenon:The fan fails in high-temperature (+85℃) or low-temperature (-40℃) environments inside the vehicle during summer or winter.
root cause:The fan uses ordinary lubricating oil, which solidifies at low temperatures and evaporates at high temperatures.
Industry Standards:Vehicle-mounted equipment requires an operating temperature range of -40℃ to +85℃.
Pain Point 3: Limited Fan Size Due to Compact Space
Phenomenon:The T-BOX and car navigation unit have extremely limited internal space, making it impossible to install a standard fan.
root cause:Vehicle-mounted equipment is becoming smaller, which severely reduces the space available for heat dissipation.
Solution:Choose an ultra-thin/micro fan (10mm or 15mm thick).
Pain Point 4: Reliability Requirements for 24/7 Continuous Operation
Phenomenon:T-BOX and vehicle networking terminals operate year-round, and insufficient fan lifespan leads to equipment downtime.
root cause:Cheap oil-bearing fans have a lifespan of only 10,000 to 20,000 hours
Industry data:Vehicle communication equipment is designed for a lifespan of 8-10 years, and the fan must be maintenance-free for 5-7 years.

IV. Key Considerations for Vehicle Communication Heat Dissipation Design
1. Seismic design
- Meets ISO 16750-3 vibration testing standards
- Shock-resistant ball bearings are selected, with an impact resistance of ≥10g.
- Fan blades reinforced to prevent breakage due to vibration.
- Use shock-absorbing pads for installation to reduce vibration transmission.
2. Wide temperature range design
- Operating temperature: -40℃ to +85℃
- Low-temperature start-up: Use low-temperature special lubricating oil.
- High-temperature operation: High-temperature resistant materials and bearings are selected.
- Thermal cycling: withstands frequent thermal shocks
3. Compact Space Design
- Use ultra-thin fans (10mm/15mm thickness).
- Select a miniature fan (25mm/30mm size).
- Consider PCB layout and airflow matching
V. Frequently Asked Questions (FAQ)
Q1: What are the special requirements for the vehicle T-BOX fan?
A: The Fengheng vehicle series is designed specifically for such scenarios, as it needs to meet the requirements of earthquake resistance, wide temperature range (-40℃~+85℃), and long life (50,000+ hours).
Q2: What should I do if the fan of my car navigation system is making a lot of noise?
A: Hydraulic bearings or anti-vibration ball bearing fans are selected, and the noise of the Fengheng anti-vibration series is controlled below 25dBA.
Q3: How long do car-mounted device fans typically last?
A: Original factory oil-impregnated bearing fans typically last 2-3 years. WindConst dual ball bearing fans can last 7-10 years.
Q4: How to solve the problem of severe overheating of the in-vehicle wireless charging module?
A: Select a miniature low-power fan, such as the Fengheng FH2510/FH3010 miniature series.<0.5W, effectively reducing charging temperature.
Q5: 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.
