One kind of outdoor display and communications equipment

摘要

An outdoor display screen and a communications device are disclosed. The outdoor display screen includes a housing (1), a display screen (2), a control module (3), a heat dissipation module (4), and a power supply component (5). A first cavity and a second cavity are disposed on the housing (1). The display screen (2), the control module (3), and the power supply component (5) are mounted in the first cavity, and the heat dissipation module (4) is mounted in the second cavity. A cable-through hole (131) is disposed on the housing (1). An air exhaust vent connected to an air intake vent of an internal circulation path and an air intake vent connected to an air exhaust vent of the internal circulation path are disposed in the first cavity to form an internal circulation heat-dissipation air duct. An air intake vent and an air exhaust vent are disposed in the second cavity to form an external circulation heat-dissipation air duct. In the outdoor display screen, an independent heat dissipation system is formed in the housing (1). Therefore, power supply and signal transmission can be implemented by using a power interface and a communications interface that are disposed in the communications device, or signal transmission can be implemented by using a pipeline cable inside the communications device and a pipeline cable in a concrete foundation. A mounting operation is simple, and a mounting difficulty in disposing the outdoor display screen is reduced.
