The invention discloses a heat dissipation device for communication equipment, and the heat dissipation device comprises a box body. An outer wall of one side of the box body is fixedly provided witha cover plate through a bolt, and the inner walls of two opposite sides of the box body are fixedly provided with the same chip through bolts. The outer wall of one side of the chip is fixedly provided with first cooling fins and second cooling fins, distributed at equal intervals, through bolts. The outer wall of one side of the cover plate is fixedly provided with second fans, distributed at equal intervals, through bolts. Moreover, the second fans have the same height as the first and second cooling fins. The outer wall of one side of the cover plate is provided with heat dissipation holeswhich are annularly distributed at equal intervals, and the heat dissipation holes have the same height as the second fans. The outer wall of the top of the box body is welded with an air incoming pipe, and one end of the inner wall of one side of the air incoming pipe is welded with a filter screen. According to the invention, the device can achieve the air convection effect in the box body, improves the effect of the heat dissipation device, quickly reduces the internal temperature of the box body, protects equipment from being damaged by overheating, and generates very small noise and vibration during operation.
