Specific embodiment
The following provides a specific embodiment of the present invention, it should be noted that the invention is not limited to implement in detail below
Example, all equivalent transformations made on the basis of the technical solutions of the present application each fall within protection scope of the present invention.
In the present invention, in the absence of explanation to the contrary, " forward and backward " refers respectively to be directed toward drawing in respective drawings
Outside, interior direction, " upper and lower " refer respectively to be directed toward the upper and lower direction of drawing in respective drawings.
As shown in Figure 1, a kind of plenum chamber of inverted speed distribution provided by the invention, including cabinet 1, in the cabinet 1
Equipped with the flow distribution plate 4 that cabinet is divided into front and rear；The lower section at 1 rear portion of cabinet is equipped with air inlet 2,1 front of cabinet
Front side be equipped with air outlet 3, air inlet direction it is vertical with air-out direction；The flow distribution plate 4 divides for upper, middle and lower three, the shunting
Plate top 4-1 and flow distribution plate lower part 4-3 is evenly equipped with multiple holes, and the percent opening of flow distribution plate top 4-1 is less than flow distribution plate lower part 4-3
Percent opening.
The plenum chamber of inverted speed distribution provided by the invention, by the way that flow distribution plate 4 is arranged, air-flow enters case from air inlet 2
By flow distribution plate 4 in body 1, air-flow is flowed out from flow distribution plate top 4-1 and flow distribution plate lower part 4-3, and cannot be by the middle part of flow distribution plate
4-2, the air-flow for flowing out flow distribution plate top 4-1 are sent out by 3 top of air outlet, and the air-flow of outflow flow distribution plate lower part 4-3 is by going out
It sends out 3 lower part of air port；It is less than flow distribution plate lower part 4-3 percent opening, and 4-2 in the middle part of flow distribution plate by flow distribution plate top 4-1 percent opening
It is small to ensure that 3 top of air outlet goes out wind velocity for the shunting function that not aperture reaches, and lower part goes out that wind velocity is big, and intermediate not outlet air is real
Revealing downstream on air port 3 has reversed VELOCITY DISTRIBUTION.
Specifically, setting between the flow distribution plate 4 and air outlet 3, there are two the connecting plate 5 vertical with flow distribution plate 4, two institutes
It states connecting plate 5 and is located at 4-2 in the middle part of flow distribution plate top 4-1 and flow distribution plate, 4-2 and flow distribution plate lower part 4-3 in the middle part of flow distribution plate
Junction, connecting plate 5 described in which are used to stop to flow through the air-flow of flow distribution plate top 4-1 toward the flow distribution plate lower part direction 4-3
Flowing is flowed through flow distribution plate lower part 4-3 air-flow and is flowed toward flow distribution plate top 4-1, plays barrier effect, can make 3 top of air outlet
Wind velocity is small out, and lower part goes out that wind velocity is big, and the effect of intermediate not outlet air is more preferable.
Preferably, the aperture in the hole on the flow distribution plate top 4-1 and flow distribution plate lower part 4-3 is 0.02m~0.07m,
The percent opening of the flow distribution plate top 4-1 is less than 40%；The percent opening of flow distribution plate lower part 4-3 is greater than 60%；Which makes to flow through
Flow distribution plate top 4-1 air velocity is small, and flow distribution plate lower part 4-3 air velocity is big, and it is small to ensure that 3 top of air outlet goes out wind velocity,
It is big that lower part goes out wind velocity.
Specifically, being equipped between the flow distribution plate top 4-1 and air outlet 3, flow distribution plate lower part 4-3 and air outlet 3
Flowing plate 6, the homogenizing plate 6 is vertical with connecting plate 5 to be connect, and the outlet air air-flow which has been effectively ensured air outlet 3 has
Uniformity；
Preferably, multiple holes are furnished on the homogenizing plate 6, and the aperture in the hole is 0.02m~0.07m, which is protected
The uniformity that the outlet air air-flow of air outlet 3 has had is demonstrate,proved.
Specifically, the air outlet 3 is cellular board, the thickness of the cellular board is less than or equal to 0.075m, ensure that outlet air
The outlet air airflow direction consistency of mouth 3.
Specifically, the aperture in hole is 0.02m~0.07m on the cellular board, which guarantees the general mood out of air outlet 3
The uniformity having had is flowed, and the direction of outlet air air-flow has preferable consistency.
Embodiment
As shown in figure 5, since air outlet 3 is too close with a distance from air-flow corner, air-flow also comes not using traditional plenum chamber
Anxious to change direction, most of air-flow causes air outlet top to go out wind velocity big, lower part outlet air along the outflow of upper air outlet 3
Speed is small.
Using the flow distribution plate 4 for being divided into upper, middle and lower three in the present invention, wherein the flow distribution plate top 4-1 and flow distribution plate
The aperture in the hole on the 4-3 of lower part is 0.05m, and the flow distribution plate top 4-1 percent opening is 24.3%, and flow distribution plate lower part 4-3 is opened
Porosity is 78.5%, while air outlet 3 uses with a thickness of 0.075m, aperture as the cellular board of 0.02m；From fig. 6, it can be seen that
The wind velocity out on air outlet top is small, and the speed of lower part outlet air is big, intermediate not outlet air, and the uniformity of air-flow is preferable；The present invention
Middle air-flow realizes shunting after flow distribution plate 4, flows out respectively from flow distribution plate top 4-1 and flow distribution plate lower part 4-3, the bee
Nest plate ensure that the outlet air air-flow of air outlet 3 has preferable uniformity, and the direction of outlet air air-flow has preferable consistency；
Since flow distribution plate top 4-1 percent opening is smaller than flow distribution plate lower part 4-3 percent opening, realizing 3 top of air outlet, to go out wind velocity small,
Lower part goes out that wind velocity is big, and the effect of intermediate not outlet air, i.e., downstream has reversed VELOCITY DISTRIBUTION on air outlet 3.
The present invention is additionally provided with two connecting plates 5 and homogenizing plate 6 on the basis of using flow distribution plate 4, described to flow 6 plate holes
Aperture be 0.02m；From figure 7 it can be seen that the wind velocity out on air outlet top is small, the wind velocity out of lower part is big, and centre does not go out
Wind, and the uniformity of air-flow is good.2 connecting plates 5 of the present invention block 4 top effluent stream of flow distribution plate and lower part is flowed out
Air-flow passes through connecting plate 5, and the homogenizing plate 6 ensure that the uniformity that the outlet air air-flow of air outlet 3 has had, realize air outlet
It does not blow among 3, it is small that top goes out wind velocity, and lower part goes out that wind velocity is big, and realizing downstream on air outlet 3 has reversed speed
Distribution.
