Abstract

The utility model relates to a take fan wheel of kuppe, it includes centrifugal impeller body, and centrifugal impeller body includes hub and the blade of equipartition in the hub periphery, still includes the kuppe, and the kuppe is annular and sets up with the hub is concentric, and the outer end of blade is connected with the interior anchor ring of kuppe, and directional wind-guiding passageway around kuppe, hub and the blade enclose jointly. The fan impeller with the flow guide cover effectively concentrates most of air flow to blow forwards through the action of the flow guide cover on the air flow generated when the centrifugal impeller body rotates; when the heat dissipation fan is used as a heat dissipation fan, a more efficient heat dissipation effect can be generated, and thus the temperature rise of a product is effectively reduced.

Description

Fan impeller with flow guide cover

Technical Field

The utility model relates to an air compressor, especially a fan wheel who takes kuppe of mainly used air compressor.

Background

Referring to fig. 5, there is shown a conventional impeller 2, which includes a hub 21 having a shaft hole at the center thereof and blades 22 extending radially outward from the hub and having a certain twist; when the impeller 2 rotates, the generated airflow includes an axial airflow and a centrifugal airflow (airflow spreading in a diameter direction). When the impeller is applied to an air compressor for heat dissipation, centrifugal airflow cannot be blown out of the air compressor in time, so that the heat dissipation effect is not ideal.

Disclosure of Invention

An object of the utility model is to overcome the not enough of above-mentioned prior art existence, and provide a fan wheel of taking kuppe that rational in infrastructure, produced air current can concentrate toward the direction of the front side and blow during the rotation.

The purpose of the utility model is realized like this:

the utility model provides a take fan wheel of kuppe, includes centrifugal impeller body, and centrifugal impeller body includes that hub and equipartition are at the blade of hub periphery, its characterized in that: the wind guide cover is annular and is arranged concentrically with the hub, the outer ends of the blades are connected with the inner annular surface of the wind guide cover, and the wind guide cover, the hub and the blades jointly form a wind guide channel pointing to the front and the back.

The purpose of the utility model can also adopt the following technical measures to solve:

more specifically, the outer diameter of the air guide sleeve decreases from the rear end to the front end.

As a further scheme, the inner annular surface of the air guide sleeve is an arc surface.

As a further alternative, the surface of the blade is planar.

As a further scheme, the hub is in a frustum shape, the diameter of the rear end of the hub is large, and the diameter of the front end of the hub is small.

As a further scheme, the air guide sleeve and the hub are staggered from one another back and forth along the central axis direction, and the inner end of each blade is narrow and the outer end of each blade is wide.

The utility model has the advantages as follows:

the fan impeller with the flow guide cover effectively concentrates most of air flow to blow forwards through the action of the flow guide cover on the air flow generated when the centrifugal impeller body rotates; when the heat dissipation fan is used as a heat dissipation fan, a more efficient heat dissipation effect can be generated, and thus the temperature rise of a product is effectively reduced.

Detailed Description

The invention will be further described with reference to the following drawings and examples:

referring to fig. 1 to 4, a fan impeller with a flow guiding cover comprises a centrifugal impeller body, wherein the centrifugal impeller body comprises a hub 15 and blades 11 uniformly distributed on the periphery of the hub 15, and a shaft hole 13 is formed in the center of the hub 15; the wind guide device is characterized by further comprising a wind guide cover 12, wherein the wind guide cover 12 is annular and is arranged concentrically with the hub 15, the outer end of each blade 11 is connected with the inner annular surface of the wind guide cover 12, and the wind guide cover 12, the hub 15 and the blades 11 jointly form a wind guide channel 14 which points forwards and backwards.

The outer diameter of the air guide sleeve 12 gradually decreases from the rear end to the front end. The inner annular surface of the air guide sleeve 12 is an arc surface.

The hub 15 is frustum-shaped, and has a large diameter at the rear end and a small diameter at the front end.

The air guide sleeve 12 and the hub 15 are staggered from each other in the front-back direction along the central axis direction, and the inner ends of the blades 11 are narrow and the outer ends are wide.

The surface of the blade 11 is a plane.
