Abstract
The utility model discloses a fan cover, which comprises a sidewall, wherein the sidewall is formed by connecting a plurality of side plates, and encloses an air duct; a first fan mounting plate is arranged at one end of the air duct, and an air outlet is formed in the other end of the air duct; a second fan mounting plate is arranged at the air outlet; the first fan mounting plate is fixedly connected with the sidewall; the second fan mounting plate is fixedly connected with the sidewall through connecting strips; an air inlet is formed in the first fan mounting plate. The fan cover is characterized in that the side plates are inclined relative to the first fan mounting plate, and each side plate forms a first obtuse angle Theta with the first fan mounting plate, so that air sucked into the air inlet blows out of the air outlet after being guided by the side plates.
Description
Technical field
The utility model relates to the blower fan fan housing of a kind of fan housing, particularly a kind of reverse air-out.
Background technique
Aspect traditional regulator cubicle heat radiation, utilize centrifugal blower to carry out forced air cooling dispels the heat more, the characteristics of centrifugal blower have determined that blower fan air-out mode is vertical air-out, the air intake direction that is centrifugal blower is vertical with the direction that air is blown, above-mentioned air-out mode has the defect that fluid resistance is large, the blower fan utilization efficiency is low, and above-mentioned air-out mode can not adapt to the heat radiation of the Electric Appliance Cabinet of the reverse air-out of some needs (opposite direction that air intake direction and air are blown).
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of blower fan fan housing of reverse air-out.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of blower fan fan housing, comprise sidewall, described sidewall surrounds an air channel by some side plates connections, one end in air channel is provided with the first fan installation plate, and its other end has an exhaust outlet, the exhaust outlet place is provided with the second fan installation plate, described the first fan installation plate is fixedly connected with sidewall, the second fan installation plate is fixedly connected with sidewall by connection strap, and the first fan installation plate is provided with wind inlet, it is characterized in that: relative the first fan installation plate of described side plate is obliquely installed, and side plate and the first fan installation plate angulation θ are an obtuse angle, thereby the air that wind inlet sucks is blown out after the side plate guiding from exhaust outlet.
Described the first fan installation plate is square plate, and described sidewall is formed by connecting by four blocks of side plates, and every one side of square plate is connected with a corresponding side plate.
Described connection strap is provided with four, is crossed as cross structure and arranges.
The beneficial effects of the utility model are: relative the first fan installation plate of the side plate of this fan housing is obliquely installed, and the angle θ of side plate and the first fan installation plate is an obtuse angle, thereby the air that wind inlet sucks is blown out after the side plate guiding from exhaust outlet, changed the flow direction of air, thereby changed blower fan the air-out mode, shorten fluid path, reduce resistance, improve the utilization efficiency of blower fan, above-mentioned air-out mode is applicable to some heat radiation that needs the Electric Appliance Cabinet of reverse air-out (opposite direction that air intake direction and air are blown).
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is three-dimensional view of the present utility model;
Fig. 2 is the three-dimensional view of the utility model other direction;
Fig. 3 is section profile schematic diagram of the present utility model.
Embodiment
Referring to figs. 1 through Fig. 3, the utility model discloses a kind of blower fan fan housing, comprise sidewall, described sidewall surrounds an air channel by 1 connection of some blocks of side plates, one end in air channel is provided with the first fan installation plate 2, and its other end has an exhaust outlet 4, exhaust outlet 4 places are provided with the second fan installation plate 7, described the first fan installation plate 2 is fixedly connected with sidewall, the second fan installation plate 7 is fixedly connected with sidewall by connection strap 6, the first fan installation plate 2 is provided with wind inlet 3, centrifugal blower 5 is arranged on the first fan installation plate 2 and the second fan installation plate 7, centrifugal blower 5 sucks wind from wind inlet 3, relative the first fan installation plate 2 of described side plate 1 is obliquely installed, and side plate 1 and the first fan installation plate 2 angulation θ are an obtuse angle, thereby the air that wind inlet 3 sucks is blown out after side plate 1 guiding from exhaust outlet 4.
In this specific embodiment, the first fan installation plate 2 is square plate, described sidewall is formed by four side plate 1 seamless links, and every one side of square plate and corresponding side plate 1 seamless link, certainly said structure is a specific embodiment, the first fan installation plate 2 also can be the arbitrary polygon plate, and sidewall is by equating that with the limit number 1 seamless link of piece side plate forms, and when the limit number is infinity, side plate 1 just surrounds a cylinder, and the first fan installation plate 2 is also a plectane, it is little that the air channel that side plate 1 surrounds forms a port, and the large structure in another port, and from wind inlet 3 to exhaust outlet 4, the sectional area in air channel evenly increases gradually, thereby relative the first fan installation plate 2 of side plate 1 is obliquely installed, and side plate 1 and the first fan installation plate 2 angulation θ are an obtuse angle, namely 90
o<θ<180
o.
In order to increase the installation strength of the second fan installation plate, exhaust outlet 4 places are provided with four connection straps 6, and the two ends of this connection strap 6 are fixedly connected with sidewall and the second fan installation plate 7 respectively, and connection strap 6 is crossed as cross structure and arranges.
Above-mentionedly just preferred embodiments more of the present utility model are illustrated and describe; but mode of execution of the present utility model is not restricted to the described embodiments; as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
