Description
Technical field
The utility model belongs to ventilation and cooling system technical field, and in particular to a kind of labyrinth type rainwater-proof fan housing.
Background technology
In ventilation, cooling system, need to be got in from outdoor extraction fresh air (or into equipment, it is cold to equipment
But), but it is not intended to the place that rainwater gets in (or in equipment) with the wind.
In the prior art, ventilation, cooling system, there are shortcomings in its inlet scoop：First, because of cost reason or to humidity
Less demanding, some is without rain cover；Second, some is bad by exhaust outlet pattern design, waterproof effect by inlet scoop rain cover；
Third, some is curved by air draught mouth down, though there is certain rain-proof effect, but rain enters with the wind.
Utility model content
Purpose of utility model：In order to solve the problem that prior art, the utility model, which provides a kind of labyrinth type, to be prevented
Rainwater fan housing, effectively prevent rainwater from entering air channel with the wind, there is universal practical value to the design and construction of suspended hood.
Technical scheme：To reach above-mentioned purpose, the utility model adopts the following technical scheme that：
A kind of labyrinth type rainwater-proof fan housing, including fan housing and plate plate, described bottom plate is fixed on the periphery of wind path wall, described
Fan housing be located on wind path wall, insert in fan housing at the top of described wind path wall, shape between the bottom of described fan housing and bottom plate
Enter the region in air channel into air-flow.
It is air channel in described wind path wall, air channel is connected by wind passage mouth with system pipeline, and system pipeline is arranged on wall
On.
The a diameter of D of described wind passage mouth, described fan housing are cylindrical, a diameter of 2D of fan housing top surface, described fan housing
Highly it is 2D.
0.25D at the top of described wind path wall distance from top fan housing.
Described bottom plate is circular ring, and circular ring external diameter isCircular ring internal diameter is D.
Beneficial effect：Compared with prior art, a kind of labyrinth type rainwater-proof fan housing of the present utility model, by changing air-flow
Direction and flow velocity, rainwater sink under gravity, so as to reach the purpose that rainwater separates with gas.The suspended hood makes letter
Single, cost is cheap, and can prevent rainwater from entering air channel with the wind well, has universal practicality to the design and construction of suspended hood
Value.
Brief description of the drawings

Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model is furtherd elucidate, it should be understood that following specific embodiments are only
For illustrating the utility model rather than limitation the scope of the utility model, after the utility model has been read, this area
Modification of the technical staff to the various equivalent form of values of the present utility model falls within the application appended claims limited range.
As Figure 1-3, reference is as follows：Fan housing 1, wind path wall 2, bottom plate 3, wall 4, system pipeline 5, wind passage mouth 6,
Air channel 7, air-flow 8 and rainwater 9.
A kind of labyrinth type rainwater-proof fan housing, including fan housing 1 and bottom plate 3, bottom plate 3 are arranged on the periphery of wind path wall 2, fan housing 1
It is located on wind path wall 2, the top of wind path wall 2 is inserted in fan housing 1, and air-flow 8 is formed between the bottom of fan housing 1 and bottom plate 3 and enters inlet air
The region in road 7.It is air channel 7 in wind path wall 2, air channel 7 is connected by wind passage mouth 6 with system pipeline 5, and system pipeline 5 is arranged on wall
On body 4.
When rainwater 9 drips, small part rainwater 9 enters in fan housing 1 with air-flow 8, but because fan housing 1 is inserted at the top of wind path wall 2
It is interior, the region into air channel 7 for obstructing this small part rainwater 9 is formd, by changing the direction of air-flow 8, air-flow 8 enters from below
Enter air channel 7, make the direction of air-flow 8 with the gravity direction of rainwater 9 on the contrary, preventing a part of raindrop from entering air channel.
Wherein, 6 a diameter of D of wind passage mouth, fan housing 1 are cylindrical, then a diameter of 2D of the top surface of fan housing 1, the height of fan housing 1 are
2D, the top of wind path wall 2 are inserted in fan housing 1, and the top 0.25D of 2 distance from top fan housing of wind path wall 1, bottom plate 3 is fixed on wind path wall 2
Periphery, bottom plate 3 are circular ring, and circular ring external diameter isCircular ring internal diameter is D.
Changing the flow velocity of air-flow 8, after air-flow 8 enters fan housing 1, channel cross-section increases more than 2 times, and the flow velocity of air-flow 8 reduces, with
The rainwater 9 that wind enters, because speed reduces, sink under gravity, further reach the purpose that rainwater 9 separates with gas.
The utility model is by changing direction and the flow velocity of air-flow, and rainwater 9 sinks under gravity, so as to reach rainwater
9 purposes separated with gas.The suspended hood makes simply, and cost is cheap, and can prevent rainwater from entering air channel with the wind well, right
The design and construction of suspended hood has universal practical value.
