Description
Technical field
The present invention relates to field of set-top, specifically the adjustable heat dissipation base of a kind of Set Top Box.
Background technology
Digital video switching box (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.
At present, the television set in domestic electric appliances has entered the digital remote control TV epoch, and viewing TV has become huge numbers of families' amusement in evening, the instrument of killing time, the prolongation of the time of opening along with television set, and the frequency of utilization of Set Top Box is also more and more higher.Because cassette mechanism of set-top box operational environment is comparatively strict 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 addition, cassette mechanism of set-top box also has higher requirements to dust-proof, and movement is after working long hours, if do not do dust-proof process, dust is as easy as rolling off a log enters cassette mechanism of set-top box, thus produces considerable influence to the life-span of cassette mechanism of set-top box.
Therefore, be necessary to provide a kind of novel radiator structure to solve the problem of Set Top Box radiating dustproof.
Summary of the invention
According to the technical problem of above-mentioned proposition, and provide a kind of Set Top Box adjustable heat dissipation base.The present invention mainly utilizes and set up heat dissipation base bottom Set Top Box, forms cross-ventilation by the louvre in induced draught fan air draught and Set Top Box, thus plays the effect of heat radiation.
The technological means that the present invention adopts is as follows:
The adjustable heat dissipation base of a kind of Set Top Box, comprises heat dissipating housing main body and the kuppe being fixed on described heat dissipating housing main body lower end; It is characterized in that:
Described heat dissipating housing main body is made up of four pieces of dust excluding plates, horizontal direction cross section is the hollow frame of rectangle, and the thickness of described dust excluding plate is 0.5mm-5mm, and described hollow frame inside is installed with radiator fan, and described radiator fan is induced draught fan;
Described kuppe is from the stiff end with described heat dissipating housing main body downwards in gradual-enlargement type structure, and described kuppe is isosceles trapezoid perpendicular to the cross section of horizontal direction, and the height of described kuppe is the half of described heat dissipating housing body height;
The lower end of described kuppe is provided with at least 3 bearings for adjustment, and described bearing comprises the adjustable prop fixed with described kuppe and the slipmat be nested with in described pillar bottom.
As preferably, the dust excluding plate top of described heat dissipating housing main body be provided with multiple for described Set Top Box bottom the magnetic fastener that adsorbs, be provided with the gap for air circulation between every two adjacent magnetic fasteners, the distance in described gap equals the width of the magnetic fastener of twice.
As preferably, the dust excluding plate of described heat dissipating housing main body is made up of at least two-layer Air Filter, and described Air Filter is provided with many reinforcements.
Comparatively prior art is compared, and heat dissipating housing main body provided by the invention is made up of dust excluding plate, and dust excluding plate adopts two-layer above Air Filter to make, and Air Filter is provided with reinforcement, and dust excluding plate can play the effect of dust-proof support; Heat dissipation base is adsorbed on bottom Set Top Box by magnetic fastener, starts induced draught fan, air is sucked in the kuppe of bottom, then discharged by the gap between magnetic fastener, form the distribution channel of side air-out in lower air draught; Be provided with bearing bottom kuppe provided by the invention, described bearing can be set to telescopic bearing, and rest base adopts slipmat to arrange, and guarantees resistance to overturning.
It is simple that the present invention has structure, and practical, the advantages such as perfect heat-dissipating, the present invention extensively can promote at Set Top Box field of radiating for the foregoing reasons.
