Detachable radiator for set top box

Abstract

The invention discloses a detachable radiator for a set top box. The radiator comprises a fixed hood body and an air guide hood fixed at the lower end of the fixed hood body, and is characterized in that the fixed hood body is a hollow frame which comprises four dustproof boards; the cross section of the hollow frame in horizontal direction is rectangular; a plurality of bulges are arranged on the inner side wall of the hollow frame; a gap for air circulation is arranged between every two adjacent bulges; the fixed hood body is fixed at the bottom of the set top box through the bulges and friction of the fixed hood body and the side wall of the set top box; a cooling fan is fixedly arranged inside the hollow frame and is an induced draft fan; a storage box for placing a set top box remote controller is also arranged outside the fixed hood body; the air guide hood gradually expands downwards from the fixed end of the air guide hood fixed on the fixed hood body; and the section of the air guide hood vertical to horizontal direction is an isosceles trapezoid. The radiator has the advantages of simple structure, strong practicability and good heat dissipation effect.

Description

technical field [0001] The invention relates to the field of set-top boxes, in particular to a heat sink for a detachable 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 ...

AI Technical Summary

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
