Description

[0001] The utility model relates to a high-temperature resistant axial flow fan, belonging to the technical field of axial flow fans. Background Art

[0002] Axial flow fans are a type of ventilation equipment widely used in industries such as industry, agriculture, construction, and transportation. They use a motor to drive the impeller to rotate, generating airflow and achieving air flow and ventilation. Traditional axial flow fans usually operate in room temperature environments. Their materials and structural design are not suitable for high-temperature operating conditions. In high-temperature environments, components such as the fan blades and motor are susceptible to thermal deformation, fatigue, and aging, resulting in decreased fan performance and even failure. After searching, it was found that Chinese patent publication number CN219711866U discloses an axial flow fan impeller and an axial flow fan. In this patent, the axial flow fan is fixed inside the casing, and one end of the axial flow fan is connected to the impeller through a rotating end. The outer wall of the support frame is fixedly connected to the inside of the casing via multiple support rods to fix the axial flow fan. The motor is started to drive the impeller to rotate, thereby driving rapid air flow. However, in high-temperature operating scenarios, the heat generated by the motor during operation cannot be directed and dissipated, causing the motor to malfunction due to excessive temperature.
