Specific embodiment
As shown in Figure 1, in a communication equipment, it will usually configure a variety of different veneers being arranged in parallel, veneer exists
After being inserted into the sub- frame of communication equipment, design to form several independent air passages by the box body structure of upper and lower corresponding veneer, it is single
The ventilating air of cooling is usually useful in plate.
As shown in Figure 2, Figure 3 and Figure 4, the mould of high-power veneer, small-power veneer and unassembled component is corresponded to respectively
The internal structure of quasi-simple plate 10, the power consumption of these veneers have very big otherness.In usual low-power consumption veneer because device density,
Heat dissipation element is less etc., smaller to the flow resistance of air, causes substantial amounts of cooling air can be preferentially by these veneers, and by big
The cooling air ratio of power consumption veneer is then smaller, causes communication equipment heat dissipation uneven.To ensure high-power veneer in equipment
Heat dissipation, then also need to improve through the total blast volume of communication equipment, and then cause equipment cooling energy consumption, noise of equipment discharge value
Increase.In order to which the requirement of equipment Homogeneouslly-radiating and noise reduction can be met simultaneously, the present invention is made in detail with reference to Figure of description
Thin explanation.

Center in favor of heat dissipation.
On the arbitrary medial surface of box body noise reduction water conservancy diversion module 5, the protrusion of noise reduction water conservancy diversion module 5 are arranged in the prominent part of to tray interior
Direction is perpendicular to the flow direction of box body interior air-flow.According to actual conditions, with reference to the radiating requirements of the veneer of different power consumption and heat dissipation,
Hydromechanical principle, can in box body the non-air flow direction of 6 both sides of electrical component and radiating module open area, specifically set
Put the installation site and planform of noise reduction flow-guiding structure 5.
As shown in fig. 7, in the present embodiment, the section of the noise reduction water conservancy diversion module 5 is preferably designed as isosceles trapezoid, isosceles ladder
The upper bottom of shape is connected towards the inside of box body, bottom with the inner wall of box body, and two waists of noise reduction water conservancy diversion module 5 are respectively formed two and lead
Stream interface 11, guide face 11 are respectively facing and are directed at air inlet and air outlet, which can reduce stream during air flow
Resistance increases systematic air flow, so as to reduce the rotating speed of equipment fan and power, the noise of equipment is reduced from source.It is further excellent
Selection of land, the noise reduction flow-guiding structure 5 are two and are respectively arranged at the both sides of component and radiating module 6.In this way, according to fluid force
Principle is learned, cooling air can quickly and efficiently pass through the surface or corresponding of radiating element 6 under the guide functions of guide face 11
Component, and the flow section of box body is largely obstructed by noise reduction water conservancy diversion module 5, and cooling air can be along radiating element 6
Surface passes through, and so as to greatly reduce the reduction for the radiating efficiency that cooling air bypass belt comes, improves cooling efficiency.In addition,
Convex block 12 can also be set on the lateral surface of water conservancy diversion module 5 by making an uproar, and effectively increase noise absorbent area.
In the present embodiment, the external structure of noise reduction water conservancy diversion module 5 is preferably designed to layer protective layer 8, the protective layer 8
Outer surface is evenly equipped with through hole 9, sound-absorbing material is also preferably filled in protective layer 8, with reference to actual conditions, the material of protective layer 8
