Description
Technical field
The utility model relates to communications industry technical field, particularly a kind of Web TV Set Top Box.
Background technology
Digital video switching box (English: Set Top Box, be called for short STB), box on so-called Set Top Box or machine is the equipment connecting television set and outside source.The digital signal of compression can be changed into television content by it, and shows on a television set.Signal can from wire cable, satellite antenna, broadband network and terrestrial broadcasting.Except the image that the content that Set Top Box receives can provide except simulated television, sound, be more to receive data content, comprise electronic program guides, internet webpage, captions etc.Make user can watch digital television program on existing television set, and carry out interactive digital amusement, education and commercialization activity by network.
All can arrange the mainboard of different components and parts in Set Top Box, wherein cpu chip is as heating element, and its cooling requirements is higher, so a fin all can be installed usually additional on CPU in producer, to ensure that it normally runs.But the people due to city life become more and more residence, often keep the house and see that TV is surfed the Net, bring great challenge will inevitably to like this heat sinking function of Set Top Box, cause greatly shorten the useful life of a lot of Set Top Box.In addition; in order to solve these heat dissipation problems, a lot of producer just offers multiple louvre at the left and right sides of Set Top Box, rear wall and top, and the air-flow that these louvres are introduced often can form intersection, sinuous flow; cause hot gas normally to arrange outward, the radiating effect of Set Top Box is reduced further.
Therefore be necessary to carry out technological innovation further to the structure of existing Set Top Box.
Summary of the invention
The purpose of this utility model is defect for prior art and deficiency, provides a kind of structure simple, Web TV Set Top Box reasonable in design, easy to use.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of Web TV Set Top Box described in the utility model, comprise box body, box body inner chamber is provided with mainboard, described mainboard is fixedly installed CPU, CPU is fixedly installed radiating block, radiating block is transversely arranged at intervals with several fin, between every two fin, forms a heat dissipation channel; The left and right sides wall of described box body is symmetrically arranged with several air admission holes, the rear wall of described box body is provided with several steam vents, box body inner chamber is provided with left air channel and right air channel, one end, left air channel is connected with the air admission hole of box portion left inwall, one end, right air channel is connected with the air admission hole of box portion right inwall, the left air channel other end converges connection mutually with the right air channel other end, the setting corresponding with heat dissipation channel of this convergence link.
Further, described air admission hole and box side wall are provided with angle.
Further, described steam vent parallels setting with box body rear wall.
After adopting said structure, the utility model beneficial effect is: a kind of Web TV Set Top Box described in the utility model, comprise box body, box body inner chamber is provided with mainboard, described mainboard is fixedly installed CPU, CPU is fixedly installed radiating block, radiating block is transversely arranged at intervals with several fin, between every two fin, form a heat dissipation channel; The left and right sides wall of described box body is symmetrically arranged with several air admission holes, the rear wall of described box body is provided with several steam vents, box body inner chamber is provided with left air channel and right air channel, one end, left air channel is connected with the air admission hole of box portion left inwall, one end, right air channel is connected with the air admission hole of box portion right inwall, the left air channel other end converges connection mutually with the right air channel other end, the setting corresponding with heat dissipation channel of this convergence link.When using the utility model, dredging heat radiation by arranging left air channel and right air channel, drastically increasing the heat sinking function of box body inner chamber, effectively extend the useful life of Set Top Box; It also avoid that intersecting appears in air-flow that louvre in the past introduces, the phenomenon of sinuous flow.It is simple that the utility model has structure, arranges rationally, the advantages such as cost of manufacture is low.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1-2, a kind of Web TV Set Top Box described in the utility model, comprise box body 1, box body 1 inner chamber is provided with mainboard 4, described mainboard 4 is fixedly installed CPU5, CPU5 is fixedly installed radiating block 6, radiating block 6 is transversely arranged at intervals with several fin 6-1, between every two fin 6-1, form a heat dissipation channel; It is characterized in that: the left and right sides wall of described box body 1 is symmetrically arranged with several air admission holes 1-2, the rear wall of described box body 1 is provided with several steam vents 1-1, box body 1 inner chamber is provided with left air channel 2 and right air channel 3, one end, left air channel 2 is connected with the air admission hole 1-2 of the left inside wall of box body 1, one end, right air channel 3 is connected with the air admission hole 1-2 of the right inside wall of box body 1, left air channel 2 other end converges connection mutually with right air channel 3 other end, the setting corresponding with heat dissipation channel of this convergence link.Operation principle of the present utility model is: user can by the place of the air admission hole 1-2 of left and right sides wall towards air comparatively convection current, so just, more wind can be sucked and enter left air channel 2 and right air channel 3, these wind are transported to heat dissipation channel by left air channel 2 and right air channel 3 again, wind through heat dissipation channel is discharged by steam vent 1-1 again, thus plays the effect of natural wind heat radiation; Not only energy-conservation, but also quiet!
As a kind of optimal way of the present utility model, described air admission hole 1-2 and box body 1 sidewall are provided with angle, and the angle number of degrees are preferably 15 ~ 40 degree.Be conducive to air inlet like this, the sidewall between air admission hole 1-2 can stop the dust in front, effectively prevents dust from entering box body 1 inner chamber.
As a kind of optimal way of the present utility model, described steam vent 1-1 parallels setting with box body 1 rear wall, is conducive to like this distributing hot gas.
When using the utility model, dredging heat radiation by arranging left air channel and right air channel, drastically increasing the heat sinking function of box body inner chamber, effectively extend the useful life of Set Top Box; It also avoid that intersecting appears in air-flow that louvre in the past introduces, the phenomenon of sinuous flow.In addition, this structure is simple, reasonable in design, low cost of manufacture.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
