Description
Technical field
The utility model relates to electronic product radiating equipment technical field, is specifically related to a kind of set top box radiating device.
Background technology
Digital video switching box (SetTopBox is called for short STB), box on so-called Set Top Box or machine, is the equipment of a connecting TV machine and outside source. It can change into television content by the data signal of compression, and shows on television set. Signal can be from wire cable, satellite antenna, broadband network and terrestrial broadcasting. The content image that can provide except simulated television that Set Top Box receives, sound, be more to receive data content, comprise electronic program guides, internet webpage, captions etc. Make user on existing television set, watch digital television program, and can carry out interactive digital amusement, education and commercialization activity by network.
At present, television set in domestic electric appliances has entered the digital remote control TV epoch, watch TV to become huge numbers of families' amusement in evening, the instrument of killing time, so the time that television set is held can be very long, and the frequency of utilization of Set Top Box is also more and more higher, because cassette mechanism of set-top box working environment is stricter to temperature requirement, general temperature requirement, between 25 DEG C to 70 DEG C, therefore becomes one of pith solving whole properties of product to the heat radiation of cassette mechanism of set-top box; In existing powerful Set Top Box, can be designed with fan, dispel the heat with the inside to Set Top Box. But, after this set-top-box opening that is designed with fan, fan just rotates at once evenly, no matter and the temperature of Set Top Box inside height, its rotating speed is all constant, time one is long, and in Set Top Box, temperature will be high and can not fall, and just likely damages Set Top Box, not only affect people's the watching of TV, meanwhile, can cause the potential safety hazard of circuit, threaten to people's safety.
Therefore,, for the problems referred to above, the utility model proposes a kind of new technical scheme.
Utility model content
