By arranging the first driving member 140 in the noise reduction ventilation cooling device 10, the noise reduction ventilation cooling device 10 can drive air to flow back and forth along the flow paths of the first air port 110, the noise elimination through hole 131 of the noise elimination member 130 and the second air port, so as to realize ventilation between the outside and the inside of the tunnel system.
As will be readily understood, referring to fig. 2, when at least two noise dampers 130 are provided, the number of the driving members is the same as that of the noise dampers 130, and the driving members correspond to the noise dampers 130 one by one, so that air can be driven to flow between the first tuyere 110 and the second tuyere through the noise damping through holes 131 of the noise dampers 130 at each noise damper 130.
Alternatively, the first drive 140 may be a fan.

In some embodiments, referring to fig. 2, the cooling assembly 200 includes a second driving member 230, the second driving member 230 is disposed between the ventilation cavity 120 and the cooling cavity 210, and the second driving member 230 is used for driving air to flow between the ventilation cavity 120 and the cooling cavity 210.

Compared with the mode that the noise reduction device and the cooling tower, the ventilation device and other heat dissipation and ventilation facilities are respectively and independently arranged in the traditional tunnel system, the noise reduction and ventilation cooling device 10 integrates noise reduction, ventilation and cooling, namely, a noise reduction, ventilation and cooling combined device is used, and the noise elimination piece 130 is used for reducing noise in the ventilation process and the cooling process, so that the tunnel space occupied by the noise reduction and ventilation cooling device 10 is favorably reduced, and the problem that the noise reduction device and the heat dissipation and ventilation facilities occupy larger tunnel space in the traditional technical scheme can be solved.
In some embodiments, at least two noise reducing ventilation cooling devices 10 are provided, and all noise reducing ventilation cooling devices 10 are spaced apart. The arrangement of at least two noise-reduction ventilation cooling devices 10 in the tunnel system can enhance ventilation of the tunnel system, enhance cooling of electromechanical facilities of the tunnel system and facilitate reduction of the overall noise of the tunnel system.
In some embodiments, the noise reduction ventilation cooling device 10 has two use states of air inlet and air outlet, the use states of the noise reduction ventilation cooling devices 10 can be switched according to the real-time requirement of the tunnel system, when more fresh air is needed in the tunnel system, more noise reduction ventilation cooling devices 10 are set to be in an air inlet state, the number of noise reduction ventilation cooling devices 10 in the air inlet state is increased, and the intake of the fresh air is enhanced; when the tunnel system needs to discharge more old gas and waste gas, more noise-reduction ventilation cooling devices 10 are set to be in an air-out state, the number of the noise-reduction ventilation cooling devices 10 in the air-out state is increased, and the discharge of the gas in the tunnel system is enhanced.
