Enhanced Cooling Performance: The San Ace 60 9CRH DC Fan
Design engineers are constantly seeking better cooling for high-performance equipment such as GPU servers. The San Ace 60 9CRH Counter Rotating DC Fan from SANYO DENKI offers significant improvements over its predecessor (9CRA type) in a familiar 60 × 60 × 56 mm size. This blog highlights the key technical advancements that deliver higher airflow, higher static pressure, and lower power consumption.
Key Technology Improvements for Superior Cooling
The enhanced performance of the 9CRH type DC fan is achieved through several crucial design innovations.
Upgraded Motor
This fan utilizes a highly efficient 3-phase drive motor, a step up from the previous bipolar motor. This allows for higher speeds and better efficiency, directly contributing to improved airflow and reduced power usage.
Optimized Aerodynamics
The impeller and frame have been redesigned for maximum performance. Extensive aerodynamic simulations were used to optimize for peak efficiency.
Improved Fan Blades
The shape of both inlet and outlet fan blades are optimized for high static pressure and low power consumption.
Space-Saving Frame Design
Recognizing the density of modern equipment, the frame joint has been improved.
Improved Fan Blades for Improved Cooling Performance
- The inlet fan blades now feature a shape derived from the high-performing 9HVA series, known for high static pressure and low power consumption.
- The outlet fan blades have a larger blade area for improved airflow.
Space-Saving Frame Design for Modern Equipment
- Recognizing the density of modern equipment, the frame joint has been improved.
- Protruding flanges have been eliminated, replaced with embedded joint fixtures.
- The maximum diameter of the joint is reduced by 11% (from ø72 mm to ø64 mm), minimizing protrusions and allowing more space for other components.
Performance Improvement of Design Changes
These design changes result in impressive performance improvements from predecessor model:
- Maximum Airflow: Increased by 12%.
- Maximum Static Pressure: Increased by 196%, or 2.9 times.
- Power Consumption: Reduced by 22% at the same operating airflow.
- Noise Level: Reduced by 4 dB(A) at the same operating airflow.
- Expected Life: Extended to 40,000 hours at 60°C (70,000 hours at 40°C), a 10,000-hour increase.
Environmental Benefits of 9CRH Fan
The San Ace 60 9CRH is also an eco-conscious choice:
- Eco Products Plus Certification: Certified for its reduced environmental impact.
- Reduced CO2 Emissions: 22% lower CO2 emissions over its lifecycle.
- RoHS Compliant: Uses lead-free brass material and adheres to the RoHS Directive.
Conclusion
The San Ace 60 9CRH Counter Rotating Fan offers a significant upgrade in cooling performance within the same compact footprint. Its innovative design delivers higher airflow and static pressure with lower power consumption and noise, contributing to more efficient and quieter systems. The improved frame design also provides greater flexibility for integration into dense equipment. This DC fan empowers design engineers to meet the increasing cooling demands of advanced technologies.
