Abstract
The embodiment of the utility model relates to an STB (Set Top Box), wherein radiating fins are adopted on a CPU chip to perform heat dissipation, so that the problem of bad heat dissipation effect resulted from the adoption of a mini-type fan system is solved. Without needing the fan system with extra power supply and higher cost, the cost for circuit design is reduced, the noise caused by adopting the mini-type fan system is avoided, the service life of the radiating fins is longer, and the use satisfaction of a user to the STB can be improved generally.
Description
Technical field
The utility model relates to the communications field, relates in particular to a kind of set-top box.
Background technology
Along with popularizing of Digital Television, set-top box provides interactively digitlization amusement, education and business activity by network for the user as a kind of home appliance that relies on television terminal that the integrated information business is provided.The mainboard that set-top box generally comprises shell and is welded with different components and parts (as tuner plate, cpu chip etc.), wherein cpu chip is as the heating components and parts, its heat radiation is had relatively high expectations, and general being designed to installed the small-sized fans system and dispelled the heat on cpu chip.
The inventor finds that there is following technical problem at least in prior art in implementing the utility model process:
Adopt the small-sized fans system that the cpu chip on the set-top box mainboard is dispelled the heat, its radiating effect is not good, thereby long-time use still can cause the too high deadlock situation that occurs of temperature, fan system is owing to need supply of electric power, therefore increased the circuit design cost, the fan system noise is big, cost is high and useful life is shorter, makes that the set-top box users user satisfaction can not get improving.
The utility model content
The utility model embodiment technical problem to be solved is, a kind of set-top box is provided, and to improve the radiating effect of cpu chip, reduces the set-top box cost, avoids occurring noise, improves the user satisfaction of set-top box users.
For solving the problems of the technologies described above, a kind of set-top box is provided, comprise shell, be arranged at the mainboard in the described shell and be arranged at cpu chip on the described mainboard, also be fixed with fin on the described cpu chip.
Further, described fin comprises the pedestal that is attached at described cpu chip top and from the extended radiator shutter in described pedestal top.
Further, described fin is fixed on the described cpu chip by the elastomeric element that is arranged in the gap between the described radiator shutter, and described elastomeric element two ends are individually fixed on the described mainboard.
Further, described elastomeric element is a spring, and described both ends of the spring is fixed on the described mainboard by snak link respectively.
Further, described fin material is an aluminium.Technique scheme has following beneficial effect at least:
By a kind of set-top box is provided, it adopts fin to dispel the heat on cpu chip, thereby avoided the not good problem of radiating effect that adopts the small-sized fans system to dispel the heat and caused, owing to need not extra supply of electric power and the higher fan system of cost, therefore reduced the circuit design cost, and avoided the noise problem that adopts the small-sized fans system to be caused, fin is longer useful life, has improved the user satisfaction of user to set-top box on the whole.
Description of drawings
Fig. 1 is a kind of structural representation of the set-top box of the utility model embodiment.
Fig. 2 is the another kind of structural representation of the set-top box of the utility model embodiment.
Embodiment
Extremely shown in Figure 2 as Fig. 1, the utility model embodiment provides a kind of set-top box, it mainly comprises shell 1, be arranged at the mainboard 2 in the shell 1, be arranged at cpu chip 3 and tuner plate 4 on the mainboard 2, be fixed with fin 5 on the cpu chip 3, and fin 5 comprises the aluminium base 6 that is attached at cpu chip 3 tops and from aluminium base 6 tops extended aluminium matter radiator shutter 7, the heat that cpu chip 3 is produced can be arranged diffusing by aluminium base 6 and aluminium matter radiator shutter 7, has gap 8 between the aluminium matter radiator shutter 7, fin 5 can be fixed on the cpu chip 3 by the spring 9 that is arranged in the gap 8, and spring 9 two ends are fixed on the mainboard 2 by snak link 10 respectively, because fin 5 excellent in heat dissipation effect of aluminium matter and need not extra supply of electric power and the higher fan system of cost, therefore reduced the circuit design cost, and avoided the noise problem that adopts the small-sized fans system to be caused, fin is longer useful life, has improved the user satisfaction of user to set-top box on the whole.
In addition, tuner plate 4 comprises matrix 11 and row's pin 12, matrix 11 is vertical mutually with row's pin 12, tuner plate 4 directly is connected with mother row 13 of mainboard 2 by row's pin 12, like this, has avoided tuner plate 4 to be plugged into for twice on the mainboard 2 by keyset, thereby saved the set-top box inner space, improve production efficiency, and saved owing to adopt the production cost of keyset, improved the reliability that is connected between tuner plate 4 and the mainboard 2.
As a kind of execution mode, above-mentioned fin 5 can also adopt other structure, for example aluminium heat sink 7 of waveform or bridge shape etc.; And fin 5 can also be fixed by other forms of structure, for example is arranged in cpu chip 3 tops etc. by buckle structure; The material of fin 5 can also adopt the preferable material of other radiating effects.
The above is an embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection range of the present utility model.
