Abstract
The utility model relates to a static pressure box with a rectifying device, comprising a shell, a heat insulating layer and a sound absorbing inner bore plate; an air inlet is arranged at the bottom part of the shell, an air outlet is arranged at the top part of the shell, and the rectifying device corresponding to the position of the air inlet is arranged at the lower part in the shell, the rectifying device is formed by a rectifying fence welded on four corners of the air inlet by four brackets; a plurality of air holes are uniformly distributed on the rectifying fence. In the utility model, rectifying device with the rectifying fence with a plurality of the air holes is correspondingly arranged in the air inlet of the static pressure box, the problem of loss caused by turbulence of air quantity is effectively solved, inlet air is changed into laminar flow from turbulence, air quantity loss is reduced, the running noise is reduced, the air conditioner operation is stable and reliable, and the use is comfortable.
Description
Technical field
The utility model relates to a kind of air-conditioner plenum chamber, is a kind of plenum chamber of band fairing of air-out steady air current specifically.
Background technology
In air handling system, air-conditioner is the nucleus equipment of central air-conditioning system.Mostly be provided with plenum chamber on the air-conditioner at present, directly pass through the external air feed of air outlet behind the conventional plenum chamber air intake, when the air quantity in plenum chamber flows, because the inertia of air, air quantity produces turbulent flow, and resistance is big, and flow is little, air quantity motion irregular, each parameter value of air quantity has pulsation phenomenon, causes energy loss, produces bigger noise, and air-out air-flow instability, air-conditioner uses uncomfortable.
Summary of the invention
Air-conditioner plenum chamber energy loss is big in the prior art, noise is big in order to overcome, deficiencies such as air-out instability, the purpose of this utility model provides a kind of plenum chamber with fairing, this plenum chamber can effectively solve because air inertia produces turbulent flow and cause the air-flow problem of unstable, can significantly reduce the loss of air quantity, reduce noise.
The technical solution adopted in the utility model is: a kind of plenum chamber with fairing, comprise orifice plate in shell, heat-insulation layer and the noise reduction, the bottom of shell is provided with air inlet, the top of shell is provided with air outlet, and its technical characterstic is that the bottom is provided with the fairing corresponding with the air inlet position in the described shell.
Further, described fairing is made up of through four corners that four supports are welded on air inlet honeycomb screen.
Again further, uniform array is provided with a plurality of wind holes of crossing on the described honeycomb screen.
After adopting above technical scheme, the beneficial effect that the utility model reaches is: entered in the plenum chamber by the plenum chamber air inlet, the air quantity motion is irregular, when on air quantity process fairing honeycomb screen, crossing the wind hole, turbulent wind quantitative change is originally become regular mobile laminar flow, effective solution air-flow instability, the problem that the air quantity resistance is big, flow is little, energy loss is big, significantly reduce wind loss, reduce noise, finally by plenum chamber air outlet air-out steady air current, the comfortableness of air-conditioning system is good, and is reliable.
The utility model adopts with a plurality of honeycomb screen fairing correspondences of crossing the wind hole and is arranged in the plenum chamber air inlet, effectively solve the loss problem that the air quantity turbulent flow causes, air intake is become laminar flow by turbulent flow, play the minimizing wind loss, reduce the operation noise, operation of air conditioner is reliable and stable, use is comfortable.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation of honeycomb screen.
Among the figure: shell 1, heat-insulation layer 2, orifice plate 3 in the noise reduction, air inlet 4, air outlet 5, honeycomb screen 6, support 7 is crossed wind hole 8.
The specific embodiment
Below in conjunction with drawings and Examples to the utility model structural representation.
Shown in Fig. 1,2, the plenum chamber of band fairing comprises orifice plate 3, air inlet 4, air outlet 5, honeycomb screen 6 and four supports 7 in shell 1, heat-insulation layer 2, the noise reduction.Shell 1 inwall is provided with orifice plate 3 in heat-insulation layer 2 and the noise reduction successively in plenum chamber, the bottom of shell 1 is provided with air inlet 4, the top of shell 1 is provided with air outlet 5, honeycomb screen 6 is arranged in the plenum chamber and is welded on four corners of air outlet 4 through four supports 7, and uniform array is provided with a plurality of wind holes 8 of crossing on the honeycomb screen 6.
