ABSTRACT:
A heat dissipation structure for sealed machine tools includes a motor rotor rotating to drive airflow to perform heat dissipation simultaneously. It includes a machine tool housing with a heat dissipation vent and a chamber inside, a stator in the chamber and a rotor located between the stator and the housing. The rotor and the housing wall form a swirling flow space between them. The rotor and the stator form an axial flow space between them. The swirling flow space and the axial flow space communicate through a radial airflow passage. The rotor has at least one flow directing portion. The rotor rotates relative to the stator. The stator generates thermal airflow which flows from the axial flow space through a radial airflow passage to the swirling flow space. The flow directing portion performs an exchange of cooling air and thermal airflow through the heat dissipation vent.
