In some embodiments, the controller is configured to control the driving device 3 to operate to make the heat dissipation plate 21 close the ventilation hole 11, such as the heat dissipation hole 211 is communicated with the ventilation hole 11, when the vehicle speed of the vehicle is lower than a first preset speed, or the temperature of the cabin is higher than a first preset temperature, or the vehicle is idling in place, or the temperature of a temperature control component (such as suspension rubber in the cabin) of the vehicle is higher than a second preset temperature, and the flooding sensor detects that the gutter 1 is not flooded, and the raindrop sensor detects that it is not raining; the controller is configured to control the driving device 3 to operate to enable the heat dissipation plate 21 to close the vent hole 11 when the vehicle speed is not lower than a first preset speed, or the cabin temperature is not higher than a first preset temperature, or the immersion sensor detects that water exists in the water flowing groove 1, or the raindrop sensor detects that rain falls, or the vehicle is flamed out.

The first wall surface 12 of the launder 1 can have 7 operating states, and the operating state of the sealed box 22 of the launder 1 and the results detected by the sensors are as follows:
