Description

Turbo blower

The present invention relates to a turbo blower device, and in particular, the driving unit and the control unit are formed so as to communicate with each other so that the cooling is simultaneously performed by one cooling passage, and by blowing external air to the stator, the rotor and the rotating shaft, respectively, the individual cooling is The present invention relates to a turbo blower device capable of maximizing cooling efficiency.

Generally, a blower refers to a mechanism for generating energy of a fluid, and the blower is composed of an impeller causing a flow and a casing for guiding the flow into and out of the impeller.

There are a number of methods for classifying blowers, the most common method being classification by the characteristics of the flow through the vanes, which is called Axial Blower, Radial Blower, and Mixed Flow Blower. Blower).

When the flow of air occurs in the direction parallel to the rotor shaft, it is called an axial blower. In this case, the flow direction of the impeller inlet and outlet coincides with the rotor shaft. Propeller blowers, ie ordinary household fans, belong here.

Axial blowers are used where the energy applied is primarily used to increase the velocity of the fluid, so that a lot of flow is required but not so much pressure.

The radial blower is mainly designed to increase the pressure by centrifugal force and is therefore used where pressure is needed rather than flow rate.

In addition, the centrifugal blower generally uses a spiral casing such that the impeller inlet flow is in the direction of the rotational axis but the outlet flow is in the direction perpendicular to the axis of rotation, and the tubular casing is used so that both the impeller inlet flow and the outlet flow are in the direction of the axis of rotation. This is largely distinguished.

In addition, the mixed flow blower is used when an increase in flow rate and pressure is required in the case where axial and radial flows exist together in the impeller.

In addition, new types of blowers that do not depend on the rotation of the impeller may be used for special purposes, and some may use a piezoelectric element without a motor. The blower should be appropriately selected according to its application and operating characteristics. Industrially, it is mainly used for air conditioning system, various intake and exhaust systems. The size also varies from small to large industrial blowers such as computer cooling fans.

The turbo blower, which is a kind of centrifugal blower, refers to a centrifugal blower having a relatively high pressure ratio, and the pressure ratio is increased in a centrifugal blower using a centrifugal force by rotating an impeller at a high speed in a container. The smaller ones are called centrifugal ventilators and turbo blowers, while the pressure ratios are higher than the centrifugal blowers and turbo blowers.
