ABSTRACT:
A heat dissipation system for digital electronic signboard includes a first heat dissipation subsystem disposed in a main circuit board area of a digital electronic signboard, and a second heat dissipation subsystem disposed in a computer mainboard area of the digital electronic signboard. The main circuit board area has a plurality of heat dissipation fans disposed therein, wherein one heat dissipation fan is 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 can be externally connected to an air guide pipe. The computer mainboard area can also have a plurality of heat dissipation fans disposed therein, wherein one heat dissipation fan is 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.
