Abstract:
1. A heat dissipation system for a digital electronic signboard having a first heat dissipation subsystem and a second heat dissipation subsystem, comprising: the first heat dissipation subsystem being disposed in a main circuit board area of a digital electronic signboard, the main circuit board area having at least two heat dissipation fans disposed therein, wherein one heat dissipation fan is appropriately disposed at a side of the main circuit board area, while another heat dissipation fan is disposed at a side of a power supply, and the heat dissipation fan disposed at the side of the power supply can be externally connected to an air guide pipe; the second heat dissipation subsystem being disposed in a computer mainboard area of the digital electronic signboard; the computer mainboard area having at least two heat dissipation fans disposed therein, wherein one heat dissipation fans is appropriately disposed at a side of the computer mainboard, while another heat dissipation fan is disposed on the top of a microprocessor of the computer mainboard, the heat dissipation system for the digital electronic signboard is thus formed by the above mentioned heat dissipation subsystems.
