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

The present invention discloses a heat radiating base for a set top box. The heat radiating base comprises a main body of a heat radiating hood and an air diversion hood which is fixed on the lower end of the main body of the heat radiating hood. The heat radiating base is characterized in that: the main body of the heat radiating hood is a hollow frame body which comprises four dustproof plates and has a rectangular horizontal cross section; a heat radiating fan is fixedly arranged in the hollow frame body; the heat radiating fan is an induced draught fan; a plurality of magnetic fasteners used for absorption with the bottom of the set top box are arranged on the tops of the dustproof plates of the main body of the heat radiating hood; a gap used for ventilation is formed between every two adjacent magnetic fasteners; the distance between two gaps is equal to double widths of the magnetic fasteners; the air diversion hood has a diverging structure downwards from the end fixed to the main body of the heat radiating hood; and the section of the air diversion hood perpendicular to the horizontal direction is an isosceles trapezoid. The heat radiating base has the advantages of simple structure, good practicality, good heat radiating effect and the like.
Description
technical field [0001] The invention relates to the field of set-top boxes, in particular to a 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 entered the era...
