TECHNICAL FIELD
[0001] The utility model belongs to the air supply system technical field, concretely relates to an air induction air supply system flow uniformity plate of even air outlet. BACKGROUND
[0002] In modern air induction air supply system, to realize uniform, comfortable air supply effect, commonly through the air outlet section area to achieve. However, in the case of not wishing to increase the air bellow space occupation, air supply fan and air supply port often adopt the layout of vertical placement. But this layout has obvious defects, namely, the air outlet wind speed is low near the air outlet fan side, and the air outlet wind speed is high far from the air outlet fan, leading to uneven air supply.
[0003] To solve this problem, the traditional method is to install flow uniformity plate at the air outlet. The conventional flow uniformity plate opening mode is to arrange uniform small holes of the same size, although the wind speed difference between the far end and the near end of the fan can be reduced to a certain extent, but the flow uniformity effect is still unsatisfactory, which cannot meet the application scene with increasing requirement for air supply uniformity. Therefore, it is urgent to develop a flow uniformity plate design which can further improve the flow uniformity effect. SUMMARY
[0004] In view of the above problems, the purpose of the utility model is to provide an air induction air supply system flow uniformity plate with even air outlet, which solves the problem of uneven air outlet caused by vertical placement of air supply fan and air supply port in the existing air induction air supply system.
[0005] To achieve the above purpose, the utility model adopts the technical scheme: an air induction air supply system flow uniformity plate with even air outlet, comprising a flow uniformity plate, the flow uniformity plate is installed in the inside of the fan box body and divides the inside of the fan box body into two cavities, an air outlet is formed on the side surface of the fan box body on one side of the flow uniformity plate, an air inlet is formed on the top of the fan box body, a air supply fan is installed in the inside of the fan box body above the flow uniformity plate, a plurality of air outlet holes are formed on the surface of the flow uniformity plate, and the opening rate of the air outlet hole on the flow uniformity plate decreases from the direction close to the air supply fan to the direction far from the air supply fan.
[0006] The utility model has the advantages that: through the optimization mode of hole density gradient compensation static pressure attenuation of the flow uniformity plate, the air flow speed at different positions can be adjusted more accurately, the wind speed difference between the far end and the near end of the air supply fan is effectively reduced, the air supply is more uniform, and a more comfortable indoor environment is provided for the user.
[0007] In order to ensure that the airflow is uniformly dispersed,
[0008] As a further improvement of the above technical scheme: the air outlet holes in each region with different opening rates on the flow uniformity plate are evenly distributed and formed in the region.
[0009] The beneficial effect of the improvement is that the uniformly arranged air outlet holes in each area can ensure uniform air dispersion, avoid local concentration or disorder, guarantee stable air flow regulation in each area, and realize the consistency and stability of the air outlet of the flow uniformizing plate.
[0010] In order to effectively reduce the processing difficulty of the flow uniformizing plate,
[0011] As a further improvement of the above technical solution, the diameters of all the air outlet holes distributed on the flow uniformizing plate are kept the same.
[0012] The beneficial effect of the improvement is that the design of the air outlet holes with the same diameter reduces the processing difficulty of the flow uniformizing plate on the one hand, and the design of the constant diameter avoids the vortex noise caused by the variable diameter on the other hand.
[0013] In order to effectively reduce the processing difficulty of the flow uniformizing plate,
[0014] As a further improvement of the above technical solution, the air outlet holes are round hole structures formed by stamping.
[0015] The beneficial effect of the improvement is that the round hole structure can ensure that the air flow is uniformly stressed around when passing through, maximally reduces air flow disturbance, realizes more stable flow uniformizing effect, and the round hole is easy to process and form, the structure is symmetrical, and no matter how the hole density and diameter change at different positions of the flow uniformizing plate, the air flow can be uniformly dispersed.

[0022] Example 1:
[0023] As Figure 1--3 shown: a uniform air induction air supply system flow board, including flow board 5, the flow board 5 is installed in the inside of fan box 1 and the inside of fan box 1 is divided into two cavities, the side of the flow board 5 is provided with air outlet 4 on the side of fan box 1, the top of the fan box 1 is provided with air inlet 2, the inside of the fan box 1 above the flow board 5 is installed with air supply fan 3, the surface of the flow board 5 is provided with a plurality of air outlet holes 51, and the opening rate of the air outlet hole 51 on the flow board 5 decreases from the direction close to the air supply fan 3 to the direction away from the air supply fan 3, by the optimization mode of hole density gradient compensation of static pressure attenuation of the flow board 5, the air flow velocity of different positions can be more accurately adjusted, the air velocity difference between the distal end and the proximal end of the air supply fan 3 is effectively reduced, the air supply is more uniform, a more comfortable indoor environment is provided for users, the air outlet holes 51 in each area of the flow board 5 are evenly distributed and arranged, the air outlet holes 51 evenly arranged in each area can ensure that the air flow is uniformly dispersed, local concentration or disorder is avoided, the air flow in each area is stably regulated, the consistency and stability of the air outlet of the flow board are realized, the diameters of all the air outlet holes 51 distributed on the flow board 5 remain the same, the design of the air outlet holes 51 with the same diameter reduces the processing difficulty of the flow board 5 on the one hand, and the design of the constant diameter avoids the vortex noise caused by the variable diameter, the air outlet hole 51 is a punch forming circular hole structure, the circular hole structure can ensure that the air flow is uniformly stressed around when passing through, air flow disturbance is minimized, more stable flow uniformity is realized, and the circular hole is easy to process and form, the structure is symmetrical, regardless of the change of the hole density and the diameter at different positions of the flow board, the air flow can be uniformly dispersed.
[0024] The working principle of the technical solution is as follows: in the vertical layout air supply system, the air supply fan 3 is located at the top of the fan box 1, the air flow flows downward from the top, due to the action of gravity and fluid friction resistance, the static pressure gradually attenuates along the height direction of the fan box 1, close to the air supply fan 3, the static pressure is high, but the air flow velocity is low, far away from the air supply fan 3, the static pressure is low, but the air flow velocity is high; the hole density of the flow board 5 in the high static pressure area is large, the opening rate reaches 22%, in order to reduce the local flow resistance in the form of increasing the hole density, so that more air flow passes through the air outlet hole 51, and the low wind speed is compensated; the hole density of the flow board 5 in the low static pressure area is small, and the opening rate is reduced to 8%, the local flow resistance is increased, the air flow is limited, and the wind speed is prevented from being too high; by adjusting the hole density, the local flow resistance coefficient is changed, so that the flow of each area tends to be consistent, and finally the uniform distribution of the air outlet wind speed is realized.
