AI Technical Summary
Existing streamlined air duct low-noise fiberglass fans are difficult to dissipate the heat generated by the motor in enclosed spaces, which may lead to accidents if the equipment is operated for a long time.
A low-noise fiberglass fan with a streamlined air duct was designed. It adopts a sound insulation and cooling component including a heat dissipation cylinder, a sealed cavity, an inlet pipe, an outlet pipe, a ring pipe, a heat dissipation plate, a fan, and a circulation pump to form a high-efficiency heat dissipation system. The coolant circulates to absorb the heat from the motor and transfer it to the heat dissipation plate. The fan accelerates the airflow to improve the heat dissipation efficiency. At the same time, the sound insulation cotton between the sealed frame and the sealed door reduces noise.
This achieves effective heat dissipation while reducing noise, extending motor lifespan, improving fan stability and reliability, and reducing the environmental impact of vibration.
