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.
