Problems solved by technology
Since the working environment of the set-top box core has strict temperature requirements, the general temperature requirement is between 25°C and 70°C, so the heat dissipation of the set-top box core becomes one of the important parts to solve the performance of the entire product; There are also higher requirements. After the movement has been working for a long time, if there is no dust-proof treatment, the dust will easily enter the movement of the set-top box, which will have a great impact on the life of the movement of the set-top box.
[0004] Therefore, be necessary to provide a kind of novel heat dissipation structure to solve the problem of heat dissipation and dustproof of set-top box

Abstract
The invention discloses an adjustable radiating base for a set-top box. The adjustable radiating base comprises a radiating cover body and a flow guide cover. The flow guide cover is fixed to the lower end of the radiating cover body. The adjustable radiating base is characterized in that the radiating cover body is a hollow frame, the frame is provided with a rectangular cross section in the horizontal direction and comprises four dustproof plates, the thickness of each dustproof plate ranges from 0.5mm to 5mm, and a radiating fan is fixedly arranged inside the hollow frame and is an induced draft fan; the flow guide cover is of a structure which is gradually enlarged downwardly from the end which is fixed to the radiating cover body, the flow guide cover is provided with a section in the shape of an isosceles trapezoid in the direction which is perpendicular to the horizontal direction, and the height of the flow guide cover is a half of that of the radiating cover body; at least three balance adjusting supporting seats are arranged at the lower end of the flow guide cover and comprise telescopic supporting columns and antislip pads, the telescopic supporting columns are fixed to the flow guide cover, and the antislip pads sleeve the bottoms of the supporting columns. The adjustable radiating base has the advantages of simple structure, high practicality, excellent radiating effect and the like.
Description
technical field [0001] The invention relates to the field of set-top boxes, in particular to an adjustable heat dissipation base for a set-top box. Background technique [0002] A Digital Video Converter Box (Set Top Box, referred to as STB), commonly known as a set-top box or set-top box, is a device that connects a TV to an external signal source. It can convert the compressed digital signal into TV content and display it on the TV. Signals can come from cable, satellite dishes, broadband networks, and terrestrial broadcasts. The content received by the set-top box is not only the image and sound that can be provided by analog TV, but also the data content, including electronic program guide, Internet web page, subtitle and so on. It enables users to watch digital TV programs on existing TV sets, and conduct interactive digital entertainment, education and commercial activities through the network. [0003] At present, TV sets in household electrical appliances have ent...
