AI Technical Summary
Technical Problem
Existing blower motors have poor heat dissipation when running at high speeds, leading to high temperature buildup, which affects motor lifespan and air delivery quality.
Method used
Multiple equiangular radial guide vanes are installed on the fan wheel's guide components. The blades of the guide vanes scrape the hot air emitted from the motor housing's vent holes and carry the hot air out through the fan blades, thus preventing the formation of a closed air chamber by high-speed vortices.
Benefits of technology
It effectively reduces motor operating temperature, decreases the chance of damage, extends service life, and improves heat dissipation.

Abstract
The present application provides a kind of air blower motor heat dissipation structure, it contains a motor and a fan group, motor has an output shaft rod, and fan group has at least a fan wheel arranged in the end of output shaft rod, fan wheel has a fan disc, and the periphery of fan disc has a plurality of equidistantly arranged fan blades, fan wheel is arranged with a flow guide in the surface adjacent to motor in fan disc, and the flow guide has a plurality of equiangularly arranged flow guide pieces, and the end section of flow guide piece is adjacent to the thinner blade part of motor and the thicker blade back part of the surface of fan disc, thereby, the flow guide on fan wheel can be used to generate guided airflow, so that the hot air in motor can be discharged, so that it can be quickly taken out by fan wheel, so as to achieve the purpose of heat dissipation and cooling, thereby prolonging the service life of motor.
