The high static pressure DC axial fan is a professional heat exhaust fan developed for the heat dissipation dilemma of fully sealed industrial and communication cabinets. Different from open equipment, sealed cabinets are designed with fully closed structures to prevent external dust, moisture and corrosive gas from invading internal precision equipment, but this structural feature also leads to extremely poor internal air fluidity. The heat generated by the internal high-power operating equipment cannot be discharged naturally, and ordinary low-static-pressure fans are difficult to break through the air resistance of the closed cabinet and the barrier of filter components, resulting in ineffective heat exhaust, long-term high temperature inside the cabinet, and frequent equipment overheating failures.

This high static pressure DC axial fan has been comprehensively optimized in blade structure, motor power and air duct design. Through the design of widened and thickened high-pressure blades and high-torque brushless DC motor, the fan obtains ultra-high static pressure performance, which can effectively overcome the air resistance generated by the sealed cabinet shell, dust filter screen and internal equipment layout, and realize strong and stable air exhaust. While maintaining high static pressure, the fan ensures sufficient air volume output, which can quickly and thoroughly discharge the accumulated high-temperature heat inside the fully sealed cabinet to the outside, and complete the rapid circulation of internal and external air. The fan adopts a fully sealed waterproof and dustproof structure, which can prevent air and water vapor from infiltrating from the fan gap while exhausting air, ensuring the tightness of the sealed cabinet and avoiding the impact of external environmental pollutants on internal equipment.

In terms of operating performance, the high static pressure fan has strong stability, can maintain high-power continuous operation for a long time, and is equipped with over-current, over-voltage and over-temperature protection functions to avoid fan burnout and failure. It is widely used in sealed communication cabinets, industrial control sealed cabinets, server sealed cabinets and other equipment scenarios. It perfectly solves the heat dissipation problem of closed cabinets that cannot be solved by ordinary fans, effectively ensures the constant temperature operation of internal precision electronic components, reduces equipment failure rate, and extends the service life of cabinet equipment.
