Problems solved by technology

[0004] The motor of this kind of fan device is surrounded by rubber pads or seals and is in a sealed state. The heat dissipation effect of the motor is poor and the temperature rises, which not only increases the loss of the motor, but also seriously affects its normal use; in addition, the noise of this fan device Large, the noise generated when the motor and impeller are working is easily transmitted through the air inlet of the base

Abstract

A vaneless fan device relates to a fan device. The vaneless fan device comprises a base and a nozzle arranged on the base, wherein the base contains a member for generating airstream; and the nozzle comprises an internal channel and an exhaust opening. The vaneless fan device is characterized in that the member comprises a motor base, a motor, a fixing element and an impeller; at least one part of a shell of the motor is arranged in an airstream channel between an air inlet of the base and an air outlet of the base, and directly exchanges heat with the airstream which fast flows.
