The second damper 206 is mounted to the second chamber 204 for controlling a moving resistance of the second sealing plate 202, wherein a damping coefficient of the first damper 205 is smaller than a damping coefficient of the second damper 206. Since the damping coefficient of the first damper 205 is smaller than that of the second damper 206, when the two sealing plates are subjected to the same force, the movement amount of the first sealing plate 201 is larger than that of the second sealing plate 202, that is, the gas discharge amplitude is larger than that of the water cooling pipe 207, and the specific heat capacity of water is larger than that of air, so that the cooling effect on the heating part of the signal control system is more balanced.

Specifically, the first damper 205 and the second damper 206 are both dampers with adjustable damping, and the damping force of the dampers can be achieved by adjusting the damping coefficient of the dampers, so that the control of the dampers is achieved, which is the prior art and is not described again. The controllable cooling mechanism comprises a pipeline cooler, a temperature sensor and a controller. The pipeline cooler is arranged outside the water cooling pipe 207 extending out of the cabinet 100, and can cool the water cooling pipe 207 when the pipeline cooler is started, and the pipeline cooler is of the prior art and will not be described again. The temperature sensor is used for acquiring the temperature T1 of the water cooling pipe 207 and the external temperature T2, transmitting the acquired signals to the controller, comparing the acquired temperature T1 of the water cooling pipe 207 with the first preset temperature T1 stored internally, comparing the acquired external temperature T2 with the second preset temperature T2 stored internally, controlling the opening and closing of the pipeline cooler according to the comparison result, and controlling the damping in the first damper 205 and the second damper 206. The specific control method comprises the following steps:
s100, if T1 is greater than or equal to T1, starting the pipeline cooler, increasing the damping coefficient of the first damper 205, and reducing the damping coefficient of the second damper 206; the cooling effect of the liquid on the heating part is stronger than that of the water on the heating part, and the water cooling heat dissipation process is mainly carried out at the moment.
S200, if T1 is smaller than T1, continuing to judge whether T2 exceeds a second preset temperature T2, if T2 is greater than or equal to T2, starting the pipeline cooler, increasing the damping coefficient of the first damper 205, and reducing the damping coefficient of the second damper 206; the cooling effect of water to the department that generates heat is stronger than the cooling effect of gas to the department that generates heat, mainly carries out the water-cooling heat dissipation process this moment.
S300, if T2 is smaller than T2, the damping coefficient of the second damper 206 is increased, and the damping coefficient of the first damper 205 is reduced, so that the cooling effect of the gas on the heating part is stronger than the cooling effect of the water on the heating part, and the air cooling and heat dissipation process is mainly performed at the moment.
Through the adjustment mode, the total heat dissipation capacity of the air cooling heat dissipation process and the water cooling heat dissipation process is equal to the heat productivity of the signal control system as much as possible.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
