Abstract
The utility model discloses a novel air outlet grid of an air-conditioning outdoor unit, which comprises a grid frame and a plurality of main ribs; wherein, both ends of each main rib are fixed on the grid frame; and the main ribs are distributed at safe intervals in the form of curved strips. Since the novel air outlet grid of the air-conditioning outdoor unit adopts a plurality of main ribs which are distributed at safe intervals in the form of curved strips, the air flow which flows out from an air outlet channel of the outdoor unit can smoothly pass through the grid, and moreover, the grid can effectively reduce noise, increase air volume and reduce wind resistance.
Description
Technical field
The utility model relates to air-conditioner outdoor unit, especially a kind of air outlet grate structure of air-conditioning off-premises station.
Background technology
Air outlet grate is the important component part in air-conditioner outdoor unit air channel, is last parts of air flow stream exhaust passage.Because the axial flow blower pressure head is lower, and air outlet grate is in the outermost of air-conditioner outdoor unit, often adopts fine and closely woven grid structure for the consideration of security, and windage is very big, so have very big flow losses after air communication is crossed the air-conditioner outdoor unit grid, air quantity has decline by a relatively large margin; In addition, because fan blade and air outlet grate close together, air-flow is very violent to the impact of grid, so cause noise problem easily.
Summary of the invention
The purpose of this utility model is to overcome the prior art air outlet grate and adopts network structure, and the problem that make that windage is big, lose air-flow, noise is bigger provides a kind of air quantity of air-conditioner outdoor unit that makes to promote, and reduces the air-conditioning off-premises station air outlet grate of noise.
For realizing above purpose, the wood utility model has been taked following technical scheme: a kind of air-conditioning off-premises station air outlet grate, include grid framework, comprise that also two ends are fixedly arranged on many main ribs on the grid framework, these the many curved batten forms of main rib distribute with safe spacing.
Adopt the main bead structures of curve batten form and guarantee to have certain safe spacing between the main rib, for guaranteeing good safety performance, the distance of safe spacing can either significantly improve air quantity less than 12mm, reduces noise, is not easy to cause the generation of accident again.
Also include and the cross-coupled auxiliary fastening rib of described many main ribs, these auxiliary fastening rib two ends are fixedly arranged on the described grid framework.Should can play the effect that structure is strengthened to the air outlet grate overall structure by auxiliary fastening rib, and adopt the structure of the auxiliary many main ribs of fastening rib cross-over connection of this usefulness, assembly technology is more simple and convenient, is suitable for the less air-conditioner outdoor unit of refrigeration work consumption.
Fixedly connected between the described adjacent arbitrarily main rib by at least one auxiliary fastening rib.Should can play the effect that structure is strengthened to the air outlet grate overall structure by auxiliary fastening rib, and can guarantee more air-flow space, be suitable for the bigger air-conditioner outdoor unit air outlet grate structure of refrigeration work consumption.
Described auxiliary fastening rib is many, and the spacing between any two adjacent auxiliary fastening ribs is greater than safe spacing.Because the distance between the auxiliary fastening rib is bigger than safe spacing, can be so that do not form tight network structure between auxiliary fastening rib and the main rib, guaranteed that air communication crosses the smooth and easy of air outlet grate, reduced the loss of air-flow, improve air quantity, reduced noise.
Described many parallel being distributed on the grid framework of main rib.Because the parallel distribution of main rib makes that the air output of air-flow is more even, has further reduced windage, has reduced the loss of air-flow, thereby has reduced the impulsive force of air-flow to grid, has reduced noise.
Also include the air-conditioner outdoor unit axial-flow leaf relative with the grid frame position, the radius of curvature of described main rib is between 0.1 to 1.5 times of this axial-flow leaf diameter.This ratio value of choosing by test, can avoid ratio too little as choosing, then air quantity is on the low side, can avoid higher again as the ratio of choosing, then can increase the material cost of grid master rib, thereby be chosen within this best scope, the grid that makes the main rib of curve batten form can keep bigger ventilation.
The utility model compared with prior art, have following advantage: this kind air-conditioning off-premises station air outlet grate has adopted many main ribs with the curved batten form of safe spacing distribution, make the air-flow that flows out from the off-premises station exhaust passage can pass through grid more stably, and can effectively reduce noise, improve air quantity, reduce windage.

The specific embodiment
Below in conjunction with the drawings and specific embodiments content of the present utility model is described in further details.
Embodiment one:
See also shown in Figure 1, a kind of air-conditioning off-premises station air outlet grate, include grid framework 1, and the air-conditioner outdoor unit axial-flow leaf (not shown) relative with grid framework 1 position, two ends are fixedly arranged on many main ribs 2 on the grid framework 1, and these many main rib 2 curved batten forms distribute with safe spacing 4.Main rib 2 is a fairly large number of rib, plays a crucial role in the air-conditioner outdoor unit air channel, and air duct performance is had material impact.Also include many auxiliary fastening ribs 3, these many auxiliary fastening rib 3 interconnections on these many main ribs 2, the negligible amounts of auxiliary fastening rib 3 mainly has been the structure booster action, reinforces by assisting fastening rib 3 two ends to be fixedly arranged on the grid framework 1.Spacing between the wherein any two adjacent auxiliary fastening ribs 3 is greater than safe spacing 4.
Even for guaranteeing air output, with many main rib 2 parallel being distributed on the grid framework 1.
For guaranteeing better air-out effect, the radius of curvature of main rib 2 is between 0.1 to 1.5 times of this axial-flow leaf diameter.
When present embodiment is applied to refrigerating capacity and is the air-conditioner outdoor unit of 3200W, can select the rib radius of curvature for use is the main rib of 0.25 times of impeller diameter, and the gained air quantity promotes about 5% by experiment, and noise remains unchanged substantially, further increase the radius of curvature of main rib, noise has remarkable reduction.
Embodiment two:
Different being of mode that present embodiment and embodiment one adopts auxiliary fastening rib to fixedly connected with many main ribs: it is fixedly connected to pass through at least one auxiliary fastening rib 3 between the adjacent main rib 2 of thousand meaning, this connected mode makes and forms more air-flow space between auxiliary fastening rib 3 and the main rib 2, when air output is very big, can guarantee better that air communication crosses the smooth and easy of air outlet grate, be fit to be applied to the bigger air-conditioner outdoor unit air outlet grate structure of refrigeration work consumption.
When present embodiment was applied to refrigerating capacity and is the air-conditioner outdoor unit of 10000W, can select the rib radius of curvature for use was the main rib of 0.7 times of impeller diameter, and the gained air quantity promotes about 8% by experiment, and noise reduces about 1.5dB (A) simultaneously.
Above-listed detailed description is at the specifying of the utility model possible embodiments, and this embodiment is not in order to limiting claim of the present utility model, does not allly break away from the equivalence that the utility model does and implements or change, all should be contained in the claim of this case.
