In recent years, with the popularization of multifunctional equipment such as digital signage, vending machines, and security devices, many manufacturers have increasingly higher requirements for heat dissipation solutions.
When it comes to multifunctional equipment, a common question arises: Can Sanyo fans meet the demands for high air volume, low noise, and long lifespan of such equipment?
Sanyo San Ace cooling fans are capable of satisfying the needs of multifunctional equipment, thanks to their advantages including efficient heat dissipation performance, excellent noise control, wide environmental adaptability, and flexible power compatibility.
I. Detailed Analysis of the Core Advantages of Sanyo Fans
1. Efficient Heat Dissipation Performance
（1）Combination of High Air Volume and High Static Pressure: Through fan blade designs optimized via fluid dynamics—such as optimized blade curvature and high-precision balance design—turbulent losses are reduced, and air flow efficiency is improved under the same power consumption. This enables the fans to meet heat dissipation needs both in scenarios requiring smooth air circulation and in high-density equipment or scenarios with restricted air flow. For equipment with high heat dissipation demands (e.g., servers), they can provide high air volume for heat dissipation; even for devices with thick heat sinks, they can achieve effective heat dissipation relying on high static pressure.
（2）High-Performance Motor Drive: Equipped with high-efficiency brushless motors, the fans feature low power consumption and high efficiency, and support PWM control. They can dynamically adjust the rotation speed according to heat dissipation needs, ensuring precise speed regulation while maintaining stable long-term operation—making them suitable for equipment that operates under high load for extended periods.
（3）Counter-Rotating Fan Technology: For equipment with limited space but high heat dissipation requirements (e.g., high-density servers), San Ace’s counter-rotating fans use two sets of fan blades rotating in opposite directions. This reduces turbulence, enhances the stability of air volume and pressure, and achieves higher air volume and static pressure.
2. Excellent Noise Control
The blade angle and air guide structure have been redesigned, allowing the fans to maintain strong static pressure output while keeping noise low. At the same time, soft-switching ICs are used to effectively reduce electromagnetic noise, making the fans quieter and more stable when running at low speeds. In addition, technologies such as blade leading edge turbulence reduction and fan frame boundary layer noise reduction are applied, enabling the fans to effectively reduce noise while maintaining high air volume.
3. Wide Environmental Adaptability
（1）High Protection Level: Special versions with water resistance, dust resistance, oil resistance, and high-temperature resistance are available. For example, waterproof fans have obtained IP68 certification, making them suitable for outdoor equipment; oil-resistant fans can operate stably in oil mist environments such as machine tools. The fans can adapt to a temperature range of -40°C to +85°C, allowing their application in high-temperature equipment like high-temperature lighting.
（2）Long-Lifespan Design: The adoption of double ball bearings, high-temperature resistant coils, and insulating materials ensures a long lifespan. For instance, the L10 lifespan of some fans can reach 70,000 hours in a 60°C environment, reducing maintenance and replacement frequency—making them suitable for equipment that operates 24/7.
4. Flexible Power Compatibility
Its AC/DC cooling fans can be directly connected to a 100-240V AC power supply and automatically convert to DC drive. They combine the high efficiency and long lifespan of DC fans, eliminating the need for additional configuration of high-power DC power supplies. This reduces system costs and assembly complexity, enables adaptation to various power supply environments, and allows flexible application in equipment with complex power environments such as communication devices and industrial automation control boxes.
5. Professional Technical Support
Sanyo Electric provides systematic technical support, including fan selection, air duct optimization, noise assessment, and lifespan prediction. This helps equipment manufacturers avoid the cost waste of repeated verification in the early stage of product development, realizing efficient R&D and reliable mass production. Additionally, it offers fast delivery support services to ensure that samples and mass-produced parts are available quickly.
✅ Summary: High-reliability DC fans can simultaneously meet the multi-dimensional needs of multifunctional equipment for air volume, lifespan, noise, and reliability.
II. Practical Application Cases
（1）A Technology Company in Shenzhen: The company launched the JZ7049G high-performance GPU workstation, which boasts high performance and ideal expandability. It is suitable for key applications with high standards for computing and storage, such as research institutes and universities. This equipment adopts Sanyo San Ace cooling fans to ensure heat dissipation effect when the equipment operates under high load.
（2）An IT Equipment Manufacturer (referred to as Company J): When developing a new generation of high-performance PC workstations, the company adopted the Sanyo San Ace DC cooling fan solution. By replacing the original combination of two small 40×40×28mm fans with one 60×60×25mm fan, it successfully reduced noise by 30% and increased air volume by 20%.
✅ Summary: In highly integrated, multifunctional equipment, properly selected Sanyo San Ace fan solutions can achieve a balance between cooling, low noise, energy conservation, and long lifespan.
III. Recommendations for Selecting Fans in Multifunctional Equipment
（1）Determine Heat Dissipation Requirements: Accurate calculation can be achieved through thermal simulation modeling (e.g., using tools like Flotherm). Input parameters such as the equipment’s 3D model, heat source power distribution, and ambient temperature to obtain the target air volume and air pressure, ensuring that the temperature of heating components is below the safety threshold. For low-power equipment, estimation can also be done using the formula "Power Consumption × 0.1 = Air Volume (CFM)", but this method has a relatively large error.
（2）Consider Installation Space: Measure the space available for fan installation inside the equipment, including height restrictions and planar dimensions, to determine the thickness and diameter of the fan. Meanwhile, plan the fan layout properly—for example, a closed cabinet can adopt a horizontal air duct layout with air intake at the front and exhaust at the back, while an open-type device can consider a three-dimensional convection layout with side blowing and top air extraction.
（3）Pay Attention to Bearing Type and Protection Level: Select the bearing type based on the equipment’s application scenario: oil-impregnated bearings are suitable for low-load, short-cycle equipment; hydraulic bearings can be used in medium-load, low-noise scenarios; and double ball bearings are often used in industrial scenarios with high vibration and 24/7 operation requirements.
In addition, if the equipment is used outdoors or in environments with dust, water vapor, etc., a fan with a corresponding protection level should be selected (e.g., IP67 protection level for protection against immersion and salt spray).
（4）Match Voltage and Speed Regulation Strategy: Select the fan voltage according to the equipment’s power supply conditions, ensuring that the equipment’s power supply margin is not less than 1.2 times the total fan power. If the equipment’s heat generation varies significantly, a fan with PWM speed regulation function can be selected to automatically adjust the rotation speed based on temperature; for high-precision instruments, fans with both temperature control and speed regulation functions can be chosen to achieve more precise temperature control.
（5）Take Noise Level into Account: If the application scenario of the multifunctional equipment is sensitive to noise (e.g., medical equipment, office equipment), a low-noise fan should be selected. Pay attention to the fan’s noise parameters, and choose fans with hydraulic bearings or magnetic suspension bearings (which usually produce less noise). In addition, fan blade design also affects noise—more blades generally result in better mute effects.
（6）Consider Brand and Lifespan: Prioritize fans from well-known brands such as Sanyo San Ace and AVC, as their quality and performance are more reliable. At the same time, select a fan with a lifespan that meets the equipment’s usage requirements: the service life of fans for industrial equipment is recommended to be no less than 50,000 hours, while that for high-load equipment should be no less than 70,000 hours.
✅ Conclusion:
For digital signage, vending machines, security devices, and industrial multifunctional equipment, Sanyo San Ace fan solutions have become the preferred choice for heat dissipation, low noise, long lifespan, and high reliability.
