Embodiment 1
[0020] Such as figure 1 As shown, a communication base station uses a self-cooling cable ditch, including a ditch body 1, a cable frame 2 and a cover plate 3. The bottom of the ditch body 1 is provided with a drainage channel 4 extending longitudinally along the ditch body 1, and the drainage channels 4 are connected in series. In the urban sewage discharge system, when the sewage flows in the drainage ditch 4, it can quickly take away the heat in the ditch body 1 to achieve a good cooling effect. Cooling liquid pipe 6 is installed on the top, and the cooling liquid pipe 6 is filled with cooling liquid, and the cooling liquid is water. One-way liquid inlet valve 7 and one-way liquid discharge valve 8 are respectively installed at both ends of 6. One-way liquid inlet valve 7 only allows the coolant in coolant pipe 6 to enter circulation box 5, and one-way liquid discharge valve 8 only allows The coolant in the circulation tank 5 is allowed to drain into the coolant pipe 6 .

Embodiment 2
[0026] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that: the cable rack 2 is provided with a cavity 13, the cavity 13 communicates with the cooling liquid pipe 6, and the cavity 13 is sealed and slidably connected with a sealing slider 14, The sealing slider 14 is fixedly connected to the side wall of the cavity 13 through the memory spring 15. The memory spring 15 is wound by a CuZnAl memory alloy wire. It is in a natural state at room temperature. When the temperature is higher than 65°C, it reaches its transformation temperature. Time memory spring 15 is in shortened state.
[0027] In this embodiment, when the surface temperature of the cable rack 2 is too high and reaches the metamorphic temperature of the memory spring 15, the memory spring 15 shrinks and drives the sealing slider 14 to slide, and the cooling liquid in the cooling liquid pipe 6 is sucked into the cavity 13, quickly reduce the internal temperature of the cable r...
