Embodiment
The utility model is further illustrated in conjunction with the drawings and specific embodiments.
As a specific embodiment, as shown in Figure 1 to Figure 3, a kind of modified set top box of the present utility model, including
Housing 1, the housing 1 includes the receiving cavity 10 enclosed by a foreboard 11, back plate 12, bottom plate 13 and top cover 14, accommodates
Circuit board 2 is provided with cavity 10, circuit board 2 is fixedly installed on the rear end of top cover 14, and the height of foreboard 11 is less than the height of back plate 12,
Offer to offer in air inlet duct 5, back plate 12 on foreboard 11 and miniature extraction fan 7, accommodating chamber are additionally provided with outgassing groove 6, back plate 12
The bottom of body 10 is provided with a metal bending knee-piece 3, and the lug boss 31 of the metal bending knee-piece 3 is towards circuit board 2.The bottom plate is provided with sucker
21, each corner of the housing is all provided with being set to arc chord angle 22, and the side plate bottom is evenly arranged with multiple heat emission holes 23.Simultaneously also in side
Plate bottom even designs multiple heat emission holes 23 and further improves radiating efficiency.
The utility model matching design bottom plate sucker 21, housing each corner is arc chord angle 22, plays anti-skidding anticollision effect,
So that set top box safety durable.
In the present embodiment, the back plate 12 is provided with a suspension arrangement 9, and it is integrated with back plate that the suspension arrangement 9 includes one
The projection 91 of design, raised 91 center offers suppending hole 92.Design projection 91 is to facilitate the interface of back plate and wiring to walk
Line, and it is then conveniently to hang set top box on the wall to design suppending hole, increases interior space utilization rate.
It can use as seen from Figure 3, the postmedian of metal bending knee-piece 3 has a projection 31, and its raised both sides is then to be more flat
Sliding inclined-plane, inclined-plane is slightly cambered, inclined-plane angle substantially at 45 °.
In the present embodiment, the circuit board 2 is arranged on a metallic heat radiating plate 4, and the metallic heat radiating plate 4 is fixedly installed on
Top cover rear end, the metallic heat radiating plate 4 is provided with multiple radiating fins 41.
In the present embodiment, AV interfaces 87, USB interface 81, power interface 82 and data-interface are offered in the back plate 12
83, it is respectively used to patch AV lines 88, USB line 85, power line 86 and data wire 84.
In the present embodiment, the front end of top cover 14 is provided with air inlet 141.
It is high by designing the low back plate of foreboard in the present embodiment so that be inside whole receiving cavity 10 it is preceding it is high after low sky
Between, and circuit board is set in the top rear of receiving cavity 10, a metal bending knee-piece is designed in bottom rear end, and by the projection of curved tabs
Portion corresponds to circuit board, foreboard air inlet duct 5, receiving cavity 10 and interior metal curved tabs, and back plate outgassing groove 6 entirely constitutes one and dissipated
Hot-flow flue, and the heat band for coordinating the miniature extraction fan of back plate that circuit board work is distributed to the cold air of exterior space through air channel
Go out outside receiving cavity 10, whole Duct design rationally, the radiating effect of maximum is reached using minimum space.Coordinate simultaneously and dissipate
Hot hole 23 can further improve radiating effect.
With reference to shown in Fig. 4, to the force analysis on the inclined-plane of metal bending knee-piece 3, it is assumed that when the horizontal direction for blowing into air channel
Fly wind when act on wind-force size F1 on 45 ° of inclined-plane, wind-force F1 can be simultaneously by reaction force of the inclined-plane to F1, such as
Fruit does not consider other external force factors, then the reaction force direction that F1 is subject to should be F2 as shown in Figure 4 direction, that is, hangs down
It is straight upward, but wind-force F3 is additionally contemplates that, so, the real wind direction after inclined-plane reaction force should be F4
Direction of a curve.Just because of F4, this part of wind action power, allows the wind for blowing into air channel to form certain wind in circuit board surface
Pressure, this will greatly increase the heat that wind is taken away, and can effectively reduce circuit board temperature.The effect on the inclined-plane of metal bending knee-piece is not only
Only be it is described above it is simple play a part of a reaction force to gas, pass through the force analysis of whole housing：Tiltedly
Resistance is initially formed in face of blowing into the air-flow in air channel, can thus make it that the air velocity of air channel inner bottom part is slack-off, and in air channel
The air velocity of upper part is fast, and according to hydromechanical Bernoulli equation, the speed of fluid is faster, and pressure is just smaller to be understood, wind
Overall pressure inside road is that upper part is small, and lower part is big, so, the pressure inside air channel is overall upward, and this again will be certain
Pressure of the air channel inside wind to circuit board surface is added to degree, this is also beneficial to preferably radiating.
Although specifically showing and describing the utility model with reference to preferred embodiment, those skilled in the art should
This is understood, is not departing from the spirit and scope of the present utility model that appended claims are limited, in form and details
On the utility model can be made a variety of changes, be protection domain of the present utility model.
