Abstract

------06/08/2018------(OCR) Page 1 of 1. Invention Summary: A motor with a heat dissipation structure includes a housing, enclosure, and cooling fan. The enclosure is provided with several air guides and exhibits several first inlet holes associated with the air guide fins for capturing some of the airflow generated by the cooling fan. Furthermore, the enclosure is provided with several air-catching protrusions. The housing exhibits several second inlet holes near the openings of these. The enclosure is mounted to the housing; therefore, the air-catching protrusions are positioned sequentially above the second inlet holes of the housing to capture some of the airflow. Additionally, several recesses are shown between the air-catching protrusions; therefore, some of the airflow may flow along the outer surface of the housing through the recesses for further cooling of the housing.
