DRIVE MOTOR COOLING FAN WITH MULTIPLE COOLING FAN

摘要

[0001] The present invention relates to a multi-cooling fan including a cooling unit for cooling the inside and outside of a motor unit, and more particularly to a multi-cooling unit including a power unit for converting power energy into rotational energy, A first frame coupled to an outer circumference of the first frame to cool the motor unit; a second blade coupled to an outer circumference of the first blade; A second frame which surrounds the motor unit and has an inner circumference which is tapered so as to surround the motor unit to guide the flow of air; a second frame coupled to the outer circumference of the second frame, And a cooling fan unit including a second blade having a speed. The multiple cooling fan equipped with the inside and outside co-cooling type driving motor cooling fan of the present invention further reduces the heat of the motor part by forming the first blade capable of cooling the motor part, So that the noise can be easily reduced.
