An Introduction to the 92x92x25mm DC Fan (12/24V, Ball Bearing)

In the world of contemporary electronics and industrial machinery, dependable thermal control is crucial for upholding performance, ensuring reliability, and extending product lifespan. The 92x92x25mm DC Cooling Fan, operating on either 12V or 24V, emerges as a superior and reliable choice engineered for a broad spectrum of cooling tasks. Crafted with precision and durability as priorities, this fan utilizes a ball bearing system, robust thermal plastic construction, and a meticulously designed impeller to deliver optimal airflow, minimal noise, and a long service life even in demanding situations.

High-Capability Cooling in a Compact Footprint

With physical dimensions of 92mm x 92mm x 25mm, this fan provides potent cooling power within a small form factor. Its design is perfect for installation in confined areas where efficient heat removal is paramount, such as inside computer cases, industrial control panels, telecommunication hardware, power units, and various automated systems. Despite its modest size, this DC fan achieves a peak air displacement reaching 107.5 CFM (cubic feet per minute), delivering outstanding performance for its category. This capability makes it suitable not only for routine cooling but also for scenarios where heat is generated quickly and requires immediate removal.

Resilient Construction with Premium Materials

The fan is built with a UL 94V-0 rated thermal plastic frame and impeller, guaranteeing both flame retardancy and mechanical resilience. This material choice offers enhanced safety and longevity, particularly in environments with significant thermal stress and electrical loads. The impeller's design promotes efficient air distribution, which helps to reduce turbulence and maximize pressure.

Advanced Ball Bearing Mechanism

In contrast to sleeve-bearing fans that can degrade rapidly in high-temperature conditions or when mounted vertically, this model employs a ball bearing system for a prolonged operational life and superior mechanical dependability. Ball bearings minimize friction between moving parts, which results in quieter operation, increased durability, and the ability to run continuously across a wider range of temperatures and orientations. This configuration also bolsters the fan's resistance to dust and vibration, two factors that commonly compromise fan longevity in industrial or harsh settings.

Broad Operating Voltage and Configuration Options

This DC fan is offered in both 12V and 24V DC versions, each supporting a wide operational voltage range:

• 12V models: Function between 7.0 V and 13.8 V DC.

• 24V models: Function between 14.0 V and 27.6 V DC.

This adaptability ensures the fan can be integrated smoothly into different systems without the risk of voltage-related issues. It also supports various speed settings (low, medium, and high RPM), giving users the freedom to select based on cooling needs and acoustic sensitivity.

Summary of Technical Specifications

The technical data reveals several fan models, each designed for different performance requirements:

• Maximum RPM: Reaching up to 6050 RPM for rapid air movement.

• Airflow Range: From 78.2 CFM (low speed) to 107.5 CFM (high speed).

• Static Pressure: Up to 19.56 mmH₂O, crucial for moving air through dense components or filters.

• Noise Levels: Between 46.3 and 52.8 dBA, allowing for balanced acoustics depending on the selected speed.

Power Efficiency and Input Details

This fan is designed with a strong focus on power efficiency. Depending on the model, its input power consumption varies from a mere 2.76 W to 10.8 W, helping to lower overall energy costs in long-term deployments. A lower current draw also means a reduced thermal load on the system's power supply. The motor is impedance-protected to guard against damage from stalled rotor conditions and features reverse polarity protection for safe operation, even if wiring errors occur during setup.

Operational and Storage Conditions

Engineered to perform reliably in tough environments, the fan supports a wide operating temperature range from -10°C to 70°C, with humidity resistance from 35% to 85% RH. It can also be safely stored at temperatures from -40°C to 80°C, making it suitable for global use in diverse climates.

Integrated Features for Superior Control

The fan can be equipped with advanced optional features, which enhance its versatility and control options:

• Auto Restart: Guarantees the fan resumes operation automatically after a power interruption.

• Frequency Generator (FG): Provides a tachometer signal for real-time fan speed monitoring.

• Rotation Detection (RD): Alerts the system in the event of a fan failure or stalled motor.

• Ingress Protection (IP): Enhanced sealing options are available for protection against dust and moisture.

• Pulse Width Modulation (PWM): Allows for precise control over the fan's speed based on thermal conditions.

Installation and Mounting

With standard mounting hole spacing (82.5 mm) and a 25mm depth, the fan is compatible with common mounting configurations. Each corner of the frame has a 4.5mm diameter hole, facilitating easy and secure attachment. The fan includes UL-type lead wires (red for positive, black for negative) with a standard length of 300mm, providing ample flexibility for connections.

Applications

The 92x92x25mm DC fan is well-suited for a vast range of applications, including:

• Computer Systems: Cooling for CPUs, GPUs, power supplies, and chassis.

• Industrial Control Hardware: PLCs, inverters, and relays.

• Telecommunications Gear: Switches, routers, and servers.

• Consumer Electronics: Gaming consoles and multimedia devices.

• Medical Equipment: Imaging systems and patient monitoring devices.

• Automotive Electronics: Battery systems, inverters, and infotainment cooling.

Conclusion

The 92x92x25mm DC Fan with ball bearings is a high-caliber thermal management solution that meets the rigorous demands of modern electronic systems. Offering robust airflow, quiet performance, a long lifespan, and advanced control capabilities, it is an ideal choice for users seeking a durable and efficient cooling fan for both 12V and 24V DC applications.
