I. Four Core Pain Points of Heat Dissipation in Aviation and Shipbuilding
Pain Point 1: High Reliability Requirements for Avionics
Phenomenon:The failure of fans in avionics equipment due to high altitude and high vibration environments leads to equipment malfunction.
root cause:The fan's reliability level is insufficient and cannot meet aviation standards.
Industry Standards:Avionics equipment typically requires an MTBF of ≥50,000 hours and DO-160 certification.
Pain Point 2: The stringent requirements for corrosion resistance in marine environments
Phenomenon:The marine equipment fan was corroded by salt spray, causing the bearing to seize and the PCB to short-circuit.
root cause:Use a regular fan instead of a marine-grade corrosion-resistant fan.
Industry data:The high salt spray concentration in marine environments means that ordinary fans have a lifespan of only 6-12 months.
Pain Point 3: Requirements for Wide Temperature Environments in Aviation/Shipping
Phenomenon:The fan fails to start or malfunctions in high-altitude low-temperature (-55℃) or cabin high-temperature (+85℃) environments.
root cause:The fan uses ordinary lubricating oil, which solidifies at low temperatures and evaporates at high temperatures.
Industry Standards:Aviation equipment must be able to withstand temperatures ranging from -55°C to +85°C, and ship engine rooms must be able to withstand temperatures ranging from -25°C to +70°C.
Pain Point 4: Requirements for Fan Structure in High-Vibration Environments
Phenomenon:Continuous vibration during aircraft and ship navigation can cause fan blades to break and bearings to be damaged.
root cause:The fan structure is not strong enough and lacks anti-vibration design.
Industry feedback:The vibration frequencies in a ship's engine room are complex, and ordinary fans will fail within 3-6 months.

IV. Key Considerations for Heat Dissipation Design in Aviation and Shipbuilding
1. Aviation Standard Requirements (DO-160)
- Temperature: -55℃ to +85℃, wide temperature range design
- Vibration: 2.5g~5g sinusoidal vibration, 0.1~500Hz
- Low air pressure: At an altitude of 15,000 meters, heat dissipation efficiency decreases by 30-40%, requiring derating when selecting a newer model.
- MTBF: ≥50,000 hours
2. Marine environmental protection requirements
- Salt spray test: ≥500 hours, no surface corrosion.
- Protection rating: IP54/IP65, dustproof and waterproof
- Anti-mildew: Conformal coating treatment for PCB boards
- Material: Stainless steel or aerospace-grade aluminum
3. Vibration resistance design requirements
- Shock-resistant ball bearings are selected, with an impact resistance of ≥10g.
- Fan blades reinforced to prevent resonance fracture
- Installation of shock absorber pads/shock absorber brackets
V. Frequently Asked Questions (FAQ)
Q1: What are the reliability requirements for fans in avionics equipment?
A: MTBF ≥ 50,000 hours, must pass DO-160 environmental testing (temperature, vibration, low pressure, salt spray, etc.).
Q2: Why do marine fans need to undergo anti-corrosion treatment?
A: The high salt spray concentration in marine environments can corrode the PCB and bearings of ordinary fans within weeks. Fengheng's marine-grade fans use stainless steel bearings and a conformal coating on the PCB, with a salt spray test duration of ≥500 hours.
Q3: Will the cooling effect of a fan decrease in a high-altitude, low-pressure environment?
A: Yes. As air density decreases, fan airflow will drop by approximately 30-40%. When selecting a model, it is necessary to allow for a margin or choose a high-pressure model.
Q4: Are there certification requirements for aviation/marine fans?
A: Aviation requires DO-160 certification, and marine vessels require classification society certification (such as CCS, ABS, DNV, etc.). Fengheng can assist clients in completing the relevant certification tests.
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.
