Abstract

The utility model proposes a kind of air deflector of axial flow blower, including：Cylinder；Multiple deflectors, circumference of multiple deflectors along the cylinder are evenly spaced apart to be arranged on the internal perisporium of the cylinder.According to the air deflector of axial flow blower of the present utility model, provided with deflector, fan outlet swirling eddy can be effectively reduced, improves the jet effect of blower fan, prevents the thermal current of fan outlet to be back to cooling tower air inlet.

Description

The air deflector of axial flow blower

Technical field

Blower fan technical field is the utility model is related to, more particularly to a kind of air deflector of axial flow blower.

Background technology

Conventional air-valve is generally venetian blind type structure, and windage is big, and efficiency is low.

Cylinder type air-valve is radial configuration, and wind can move under the centrifugal action of blower fan along air duct wall direction.Due to air-valve Blade is opened from round section, so be fan in the position of air duct, will be in air-valve and wind when air valve plate is opened A gap is formed between cylinder, directly affects the rectification effect of air-valve.

Utility model content

The utility model is intended to one of technical problem at least solving in correlation technique to a certain extent.

Therefore, a purpose of the present utility model is to propose that a kind of jet effect is good, can effectively reduce air outlet rotation Turn the air deflector of the axial flow blower of air-flow.

According to the air deflector of axial flow blower of the present utility model, including：

Cylinder；

Multiple deflectors, circumference of multiple deflectors along the cylinder are evenly spaced apart to be arranged in the cylinder Internal perisporium on.

Advantageously, the connection end of each deflector is connected and each deflector with the internal perisporium of the cylinder Free end point to the axis of the cylinder.

Advantageously, each deflector is welded on the internal perisporium of the cylinder.

Advantageously, each deflector is connected by screw on the internal perisporium of the cylinder.

Additional aspect and advantage of the present utility model will be set forth in part in the description, partly by from following description In become obvious, or by it is of the present utility model practice recognize.

Brief description of the drawings

Fig. 1 is the schematic diagram according to the air deflector of the axial flow blower of the utility model one embodiment；

Fig. 2 is the partial schematic diagram according to the air deflector of the axial flow blower of the utility model one embodiment.

Embodiment

Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning Same or similar element is represented to same or similar label eventually or there is the element of same or like function.Below by ginseng The embodiment for examining accompanying drawing description is exemplary, it is intended to for explaining the utility model, and it is not intended that to the utility model Limitation.

Below with reference to the accompanying drawings it is described in detail the air deflector according to axial flow blower of the present utility model.

As depicted in figs. 1 and 2, according to the air deflector of axial flow blower of the present utility model, including：Cylinder 100, it is multiple to lead Flowing plate 200.

Specifically, circumference of multiple deflectors 200 along cylinder 100 is evenly spaced apart to be arranged in cylinder 100 On perisporium.

More specifically, the connection end of each deflector 200 is connected with the internal perisporium of cylinder 100 and each deflector 200 Free end point to cylinder 100 axis.

In other words, each deflector 200 is configured generally to right angled triangle, is evenly spaced apart to be arranged in cylinder 100 On internal perisporium.For example, each deflector 200 is welded on the internal perisporium of cylinder 100.Or each deflector 200 passes through spiral shell Nail is connected on the internal perisporium of cylinder 100.

According to the air deflector of axial flow blower of the present utility model, provided with deflector, fan outlet rotation can be effectively reduced Turn air-flow, improve the jet effect of blower fan, prevent the thermal current of fan outlet to be back to cooling tower air inlet.

In description of the present utility model, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", " length ", " width Degree ", " thickness ", " on ", " under ", "front", "rear", "left", "right", " vertical ", " level ", " top ", " bottom " " interior ", " outer ", " suitable The orientation or position relationship of the instruction such as hour hands ", " counterclockwise ", " axial direction ", " radial direction ", " circumference " are based on orientation shown in the drawings Or position relationship, be for only for ease of description the utility model and simplify and describe, rather than instruction or imply signified device or Element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to limit of the present utility model System.

In addition, term " first ", " second " are only used for describing purpose, and it is not intended that instruction or hint relative importance Or the implicit quantity for indicating indicated technical characteristic.Thus, define " first ", the feature of " second " can be expressed or Implicitly include one or more this feature.In description of the present utility model, " multiple " are meant that two or more, remove It is non-separately to have clearly specific limit.
