Title:
Coreless donut type motor fan for ventilation and cooling
Document Type and Number:
Japanese Patent JP6322299
Kind Code:
B2
Abstract:
The present invention relates to a coreless donut-type fan, and more particularly, to a coreless donut-type motor fan for ventilation and cooling, in which a rotating force is generated by wings themselves, without a separate rotational power such as a motor provided in a central portion thereof, and a through hole is formed in the central portion thereof to prevent a "wind barrier" phenomenon during rotation at a high speed, thereby maintaining smooth air flow, minimizing power consumption, in particular, preventing rotational noise due to induction of smooth rotation, and improving rotational efficiency.
