Electronic stop board adopting graphene for heat dissipation

Abstract

The invention discloses an electronic stop board adopting graphene for heat dissipation. The stop board comprises a base, a stop board main body is fixedly connected to the top of the base, a displayscreen body is embedded in the front surface of the stop board main body, a loudspeaker is embedded in the top of the front surface of the stop board main body, a cavity is formed in the stop board main body, and four first mounting inner studs are fixedly connected to the front side of an inner cavity of the cavity. The electronic stop board solves the problem that a display on an electronic stop board is provided with a main board, a chip on the main board is used for main information processing, and during main board working, the chip can generate a large amount of heat, however, the purpose of heat dissipation of the chip on the main board is achieved in the mode that an aluminum sheet conducts heat, and the heat dissipation effect is poor, although a filter screen is arranged at theposition used for air inlet and air outlet, filter holes in the filter screen can be blocked due to too much external dust after long-time use, and heat dissipation of the chip on the main board is seriously affected.

Description

technical field [0001] The invention relates to the technical field of electronic stop signs, in particular to an electronic stop sign using graphene to dissipate heat. Background technique [0002] Electronic stop signs will use global satellite positioning and navigation technology, advanced communication methods, geographic information system technology, advanced video transmission technology and a new generation of application systems that are organically combined with smart sensors, making full use of the current bus intelligent dispatch management system. Bus station data, through technical docking, to establish a bus arrival forecast system. [0003] The monitors on the electronic station signs are all attached to the motherboard. The chips on the motherboard are used for main information processing. When the motherboard is working, the chips will generate a lot of heat. However, the heat dissipation of the chips on the motherboard is conducted through aluminum sheets...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of electronic stop sign that adopts graphene to dissipate heat, which has the advantages of good heat dissipation effect, and solves the problem that the display on the electronic stop sign is attached with a main board, and the chip on the main board is used for main information processing. When the motherboard is working, the chip will generate a lot of heat. However, the heat dissipation of the chip on the motherboard is achieved through the heat conduction of the aluminum sheet. , but there is too much dust in the outside world. After a long time of use, the filter holes on the filter will be blocked, which will seriously affect the heat dissipation of the chips on the motherboard.
