Connection.
Cooling system 3 can use water-cooling system, air cooling system etc..In the present embodiment, cooling system 3 uses water-cooling system.
Specifically, the water-cooling system includes water pump 31, housing 32, cold water connecting tube 33 and hot water connecting tube 34, the row of being set in of housing 32
The outside of tracheae 1, housing 32 have hollow cavity, and cold water connecting tube 33 and hot water connecting tube 34 are separately positioned on housing 32 simultaneously
Connected with hollow cavity, water pump 31 is connected with cold water connecting tube 33, and hot water connecting tube 34 is connected to the charge air cooler of automobile engine.
Temperature control system includes controller 41, and the controller 41 can be integrated in the control system of automobile, the He of water pump 31
Calibration facility 5 is connected with controller 41.The flow of water pump 31 is can control by controller 41, so as to control into silencer 2
In air-flow temperature.Into tail mouth discharge of the air-flow through silencer 2 of silencer 2, calibration facility 5 gathers going out for silencer 2
The noise of the air-flow at mouth end is simultaneously fed back in controller 41, and controller 41 adjusts the flow of water pump 31 according to the characteristic of noise.
In order to realize the flow of accurate control water pump 31, so as to control the temperature of the air-flow into silencer 2, and then make to disappear
Sound device 2 meets the requirement to frequency of noise elimination and sound deadening capacity under each operating mode.Temperature control system also includes being arranged on entering for silencer 2
First temperature sensor 42 at mouth end, first temperature sensor 42 are connected with controller 41, and entrance is set with controller 41
The a reference value of the temperature of the air-flow of silencer 2, a reference value run on the noise elimination to be reached during each operating mode with automobile engine
Frequency and sound deadening capacity match, and the first temperature sensor 42 is used for the temperature value for monitoring the air-flow for actually entering silencer 2, passes through
Controller 41 calculates the difference of the actual temperature value that the first temperature sensor 42 measures and a reference value, and controller 41 is according to the difference
The flow of value regulation water pump 31, so that the actual temperature value that the first temperature sensor 42 measures reaches a reference value, and then makes to disappear
Sound device 2 can meet the requirement to frequency of noise elimination and sound deadening capacity under each operating mode.
