Abstract

The invention belongs to the technical field of set top box protection, and particularly relates to a waterproof heat dissipation device for a set top box, which comprises a mounting box, a buckling cover, a heat dissipation mechanism and a ventilation mechanism, the mounting box is flat, the upper part of the mounting box is connected with a buckling cover, and a heat dissipation mechanism is fixedly mounted in the upper wall of the mounting box; the heat dissipation mechanism comprises a heat dissipation pipe, a heat dissipation groove, a shifting piece, a rubber plate, a friction wheel, a sealing plate, a buffer cavity, an expansion bag and a barrier film; the lower end of the heat dissipation pipe is fixedly connected into the upper wall of the mounting box, the heat dissipation pipe penetrates through the upper wall of the mounting box, and the upper end of the heat dissipation pipe is slidably inserted into the wall of the buckling cover; and when the air pressure of the cavity on the inner side of the sealing plate is increased, a barrier film in the expansion bag is subjected to large extrusion force, and then non-Newtonian fluid in the expansion bag is extruded, so that the contact resistance between the outer wall of the friction wheel and the shifting piece is more stable, and it is ensured that the shifting piece and the rubber plate can be separated from each other.

Description

technical field [0001] The invention belongs to the technical field of set-top box protection, in particular to a waterproof and heat-dissipating device for set-top boxes. Background technique [0002] Digital video conversion box (Set Top Box) referred to as STB, usually called a set-top box or set-top box, is a device that connects a TV with 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 to be able to receive digital content, including electronic program guides, Internet web pages, etc., in addition to the images and sounds that can be provided by analog TV. 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] As an electrical appliance, the se...
