Set top box with radiating function

Abstract

The invention discloses a set top box with a radiating function. The STB comprises an external lower box body, an external upper cover, an internal lower box body and an internal upper cover; the external lower box body is combined with the external upper cover, and the internal lower box body is combined with the internal upper cover; an outer protection rubber block is arranged at each of the bottom of the external lower box body and the top of the external upper cover; an inner protective rubber block is arranged on each of the bottom of the internal lower box body and the top of the internal upper cover; a damping spring is arranged at an inner cavity of the external lower box body, a cooling fin is arranged at the bottom of the inner cavity of the internal lower box body through support pillars; a radiating fan is arranged in the internal lower box body, through holes are arranged on the external lower box body, and water fenders are arranged at a left sidewall and a right sidewall of the external lower box body; connecting columns are arranged at the bottom of the external lower box body, and suckers are arranged at the bottoms of the connecting columns. The STB has a certainanti-collision capacity when the good radiating function of the STB is guaranteed, so that the STB is safer in the use process, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of set-top boxes, in particular to a set-top box with heat dissipation function. Background technique [0002] A set-top box is an abbreviation of a digital video conversion box. It is a device that connects a TV to an external signal source. It can convert compressed digital signals into TV content and display them on the TV. The signal can come from cable, satellite antenna , broadband network and terrestrial broadcasting, the content received by the set-top box is not only the image and sound that analog TV can provide, but also the ability to receive digital content, including electronic program guides, Internet pages, subtitles, etc. It enables users to watch digital TV programs on existing TV sets, and conduct interactive digital entertainment, education and commercial activities through the network.

AI Technical Summary

Problems solved by technology

It enables users to watch digital TV programs on existing TV sets, and conduct interactive digital entertainment, education and commercial activities through the network. There are complex electronic components inside the set-top box, which will generate a lot of heat during use, and improve the internal quality of the set-top box. If the temperature is too high, it will affect the normal use of electronic components, and it is necessary to dissipate heat from the set-top box, and the traditional set-top box has poor impact resistance and is easy to damage the electronic components inside the set-top box. Therefore, we propose a set-top box with heat dissipation function
