The invention discloses a communication cabinet combining water cooling and air cooling. The communication cabinet comprises a bottom plate, a cabinet body, air blowers, damping springs, damping devices, a rain-sheltering plate, a first exhaust fan, second exhaust fans, a rain collecting box, a soft water pipe, a booster pump, a hard water pipe and radiating fins, wherein each damping device comprises connecting rods, a spring and sliders. The communication cabinet has the advantages that the communication cabinet is provided with the damping springs and the damping devices, the damping springs play a damping role, vibration is transmitted to the connecting rods at the same time, the connecting rods and the springs are coordinated to allow the sliders to slide along slide grooves to perform secondary damping, a good damping effect is achieved, and electric components are protected; the communication cabinet is provided with the first exhaust fan, the air blowers, the second exhaust fans, the rail collecting box, the soft water pipe, the hard water pipe and the radiating fins, the water cooling and air cooling are combined to achieve communication cabinet radiating, radiating efficiency is increased, and a good radiating effect is achieved.
