With continued reference to fig. 3, in order to improve the heat dissipation efficiency of the optical module 2, the baffle 4 may automatically adjust the opening angle of the oblique baffle 4 according to the temperature of the optical module 2, so as to effectively utilize the total air volume of the baffle 4 to dissipate heat for the optical module 2, and improve the heat dissipation efficiency of the optical module 2, i.e. when the temperature of the optical module 2 increases, the air intake will increase, and when the air intake increases, the opening angle of the baffle 4 will be larger, the air intake flowing through the optical module 2 is larger, so that the optical module 2 can be cooled rapidly; when the temperature of the optical module 2 is reduced, the air inlet quantity is reduced, and the opening angle of the guide plate 4 is reduced after the air inlet quantity is reduced.
And in order to further promote the radiating efficiency of optical module 2, change the air inlet direction through the effect of guide plate 4 to cooperate with the heating panel 32 in the heating panel 32 subassembly 3, make the length direction flow of the heat dissipation passageway between the adjacent heating panel 32 of air inlet orientation after the change, thereby promoted the amount of wind that flows through heating panel 32 subassembly 3, and because heating panel 32 and cage body 1 form certain angle setting, increased the windward area and the amount of wind of heating panel 32, promoted optical module 2 radiating efficiency.

As shown in fig. 6, the baffle 4 is mounted on the side of the cage body 1 by the connection assembly 5, and the baffle 4 rotates around the side of the connection assembly 5, so that the baffle 4 is close to or far from the cage body 1. Specifically, the connecting component 5 may be a hinge or other connecting components 5 such as a damping member, which can realize angle adjustment, the hinge includes a rotating shaft and a spring, and the spring has a certain restoring force, so that the inclination angle of the deflector 4 can be automatically adjusted. The connection assembly 5 is of course also capable of limiting the angle between the baffle 4 and the second surface not to exceed a maximum angle. The baffle 4 is provided with angle fixing portion 41 towards one side of cage body 1 for the minimum angle between baffle 4 and the cage body 1 is restricted, and specific angle can select according to actual need, even less at the intake through setting up angle fixing portion 41, also has wind to get into in the cage body 1 from between baffle 4 and the cage body 1, thereby guarantees the radiating efficiency to optical module 2.
In order to improve the deployment density of the optical module 2, when the dual-layer optical module cage 63 is required, in a specific embodiment, the cage body 1 includes a first accommodating cavity and a second accommodating cavity which are stacked along the thickness direction of the cage body 1, the first accommodating cavity and the second accommodating cavity are both used for accommodating the optical module 2, the first accommodating cavity is a top layer located on the cage body 1, the second accommodating cavity is a bottom layer located on the cage body 1, but the optical module 2 heat dissipation capacity in the second accommodating cavity is limited, and the bandwidth improvement requirement cannot be met, so that in order to ensure the heat dissipation capacity of the optical module 2 in the second accommodating cavity, the first accommodating cavity and the second accommodating cavity are divided into two cages of the top layer and the bottom layer by a partition board, the heat dissipation plate 32 assembly 3 is arranged on the first surface of the heat dissipation plate of the cage of the top layer, and the heat dissipation plate 32 assembly 3 is also arranged on the first surface of the bottom layer cage, so that the optical module 2 in the top layer cage and the top layer cage can dissipate heat.
In a specific embodiment, the first surface of the cage body 1 has an opening 11, the second surface of the cage body 1 has an opening 11, the surface of the cage body 1 opposite the second surface has an opening 11, and the surface of the cage body 1 opposite the interface end has an opening 11. Specifically, openings 11 are formed in the periphery of the cage body 1, so that the air quantity is greatly improved, and the heat dissipation efficiency of the optical module 2 is improved.
When wind blows to the cage body 1, a part of wind enters the cage body 1 from the opening 11 of the interface end surface of the cage body 1, another part blows wind into the cage body 1 from the guide plate 4, the wind enters from the opening 11 of the second surface of the cage body 1, then can flow out from the opening 11 of the surface of the cage body 1 opposite to the second surface, can flow out from the opening 11 of the first surface of the cage body 1, and can flow out from the opening 11 of the surface of the cage body 1 opposite to the interface end, thus greatly improving the wind quantity entering the cage body 1 and further improving the heat dissipation efficiency of the optical module 2 in the cage body 1.

When the temperature of the optical module 2 and the main chip 61 increases, a fan speed regulating mechanism of the communication equipment is triggered, and the fan speed is increased. As shown in fig. 8, when the wind of the fan enters from the air inlet direction, the air speed of the air flowing through the optical module cage 63 increases, and the air flow has a thrust action on the baffle 4, and the opening angle of the baffle 4 increases until the opening angle reaches the maximum angle under the thrust action of the air flow. The larger the opening angle of the baffle 4, the larger the air quantity flowing through the optical module cage 63 and the main chip radiator 62, and the higher the heat radiation efficiency of the optical module 2. That is, the deflector swash plate device can adjust the rotation speed of the fan according to the temperatures of the optical module 2 and the main chip 61, and the wind speed of the fan is used to automatically adjust the opening angle of the deflector 4, thereby automatically adjusting the wind quantity flowing through the optical module cage 63 and the main chip radiator 62.
