The invention discloses a heat dissipation device of an LED traffic signal lamp in the technical field of traffic lights. The device comprises a base, connecting rods are arranged at the bottom of thebase. A balancing weight is arranged at the bottom of the connecting rod. Heat dissipation devices are arranged on the outer walls of the left and right sides and the rear side of the box body. A water storage tank is arranged in the top center of the box. The left side of the water storage tank is connected with a circulating water pump. The circulating water pump is connected with the serpentine channel through a connecting water pipe. An ammonium salt filling layer is arranged in an inner cavity of the shell. Brackets are arranged on the left and right sides of the top of the box. A dustproof rainproof plate is arranged at the top of the bracket. The serpentine channel slows down the flowing speed of water flow in the heat dissipation device. One part of water enters the ammonium saltfilling layer through small holes formed in the outer wall of the serpentine channel. Ammonium salt is dissolved in water to absorb heat to reduce the temperature, water in the S-shaped channel is cooled, the circulating water pump and the connecting water pipe are matched to enable water flow to be in a circulating state all the time, the cooling effect is achieved, the fan accelerates the circulating speed of air in an inner cavity of the box, and the temperature is further reduced.
本发明公开了交通灯技术领域的一种LED交通信号灯的散热装置，包括底座，底座底部设置有连接杆，连接杆底部设置有配重块，箱体左右两侧和后侧外壁均设置有散热装置，箱体顶部中心设置有储水箱，储水箱左侧通过管道与循环水泵连接，循环水泵通过连接水管与蛇形通道连接，且壳体内腔设置有铵盐填充层，箱体顶部左右两侧均设置有支架，支架顶部设置有防尘防雨板，蛇形通道减缓水流在散热装置中的流通速度，一部分水通过蛇形通道外壁设置的小孔进入铵盐填充层内，铵盐溶于水吸收热量降低温度，冷却蛇形通道中的水，循环水泵和连接水管配合使水流一直处于流通状态，达到降温效果，风机加快箱体内腔空气的流通速度，达到进一步降低温度的效果。
