风恒科技成立13年来，为全球各行业客户提供专业散热解决方案。以下是我们服务过的部分客户案例，涵盖汽车、3D打印、工业设备、医疗设备等领域。
Case 1: British Ultra-Luxury Automotive Brand
Client Background: A British ultra-luxury automotive brand, one of the world’s top automobile manufacturers, with the most stringent requirements for component reliability, vibration resistance, and wide-temperature operation.
Challenge: During the development of their next-generation flagship model, the brand needed high-reliability cooling fans for onboard ADAS domain controllers, laser headlights, and infotainment systems. Requirements included:
- Operating temperature: -40°C to +105°C
- Vibration resistance: ISO 16750-3 standard
- MTBF ≥ 50,000 hours
- EMC compatibility: Low electromagnetic interference for sensitive onboard electronics
- Certifications: CE, RoHS, REACH
Solution: Fengheng Technology provided FH3010, FH4010, and FH5015 series dual ball bearing wide-temperature fans with custom wire lengths and connector types. We completed -40°C to +105°C thermal cycle testing, vibration testing, and provided full EMC test reports and certification documents.
Result: Fengheng Technology became an approved global supply chain partner for the brand, and our products are now installed in their flagship production models worldwide.
Case 2: 3D Printer Brand Hotend Cooling Solution
Client Background: A leading domestic 3D printer brand with annual shipments exceeding 100,000 units, exporting to European and American markets.
Challenge: The brand received widespread user feedback about frequent clogging issues after 6-12 months of use. Investigation revealed that the original hotend cooling fans (sleeve bearing) experienced lubricant evaporation at high temperatures, causing bearing seizure.
Solution: Fengheng Technology provided FH4010 dual ball bearing fans as a drop-in replacement, maintaining original mounting dimensions and connector specifications.
- Lifespan increased from 8,000 hours to 50,000 hours
- Temperature rating increased from 70°C to 105°C
Result: The brand adopted Fengheng fans as standard equipment for their high-end models. Clogging-related warranty claims decreased by 70%.
Case 3: EV Charging Pile Operator Outdoor Cooling
Client Background: A leading domestic EV charging pile operator with over 100,000 DC fast-charging stations nationwide.
Challenge: Outdoor charging piles suffered fan failures due to water ingress and high summer temperatures, leading to overheating shutdowns and severely impacting station availability.
Solution: Fengheng Technology deployed FH12038 IP55-rated dual ball bearing fans with -30°C to +70°C wide-temperature operation, corrosion-resistant coating for coastal high-humidity environments, and FG tachometer feedback signals for remote monitoring.
Result: Cooling-related downtime decreased by 85%, and customer satisfaction improved significantly.
Case 4: Medical Device Manufacturer Ventilator Cooling
Client Background: A European medical device manufacturer producing ventilators and anesthesia machines for hospitals worldwide.
Challenge: The manufacturer needed ultra-quiet, low-vibration fans for patient-facing medical equipment, with strict EMC requirements to avoid interference with sensitive sensors.
Solution: Fengheng Technology provided FH5015 hydraulic bearing fans with custom low-noise impeller design (<22dBA), low-vibration motor (<0.8mm/s), and full EMC shielding.
Result: The fans met all medical device certification requirements (IEC 60601), and the manufacturer placed recurring quarterly orders.
Case 5: Data Center Server Cooling Upgrade
Client Background: A cloud service provider operating multiple data centers across Asia-Pacific.
Challenge: Existing server fans were failing prematurely due to 24/7 operation, causing unexpected downtime and increased maintenance costs. Original sleeve bearing fans lasted only 1.5-2 years.
Solution: Fengheng Technology replaced them with FH4028 and FH4056 dual ball bearing PWM fans, offering MTBF >70,000 hours, PWM speed control for optimized power consumption, and FG tachometer feedback for remote monitoring.
Result: Fan-related failures dropped by 90%, and projected fan lifespan increased to 7+ years, significantly reducing maintenance costs.
Case 6: Industrial Laser Cutter Manufacturer
Client Background: A leading manufacturer of industrial CO₂ and fiber laser cutting machines.
Challenge: Laser power supplies and control cabinets generated significant heat in dusty workshop environments, causing thermal shutdowns and component failure. Standard fans quickly clogged with dust and failed.
Solution: Fengheng Technology provided FH12038 IP55 dust-protected fans with high static pressure to overcome dust filter resistance, dual ball bearings for long life in harsh environments, and tool-free filter covers for easy maintenance.
Result: Thermal shutdowns were eliminated, and maintenance intervals extended from monthly to quarterly.
