When the above-mentioned third valve is in the first valve position, only the main pipeline is conducting, and the opening degree of the third valve is the first opening degree; when the third valve is in the second valve position, only the pipe section 02 and the bypass pipe section 06 are entered When the third valve is in the third valve position, the third valve has the second opening; when the third valve is in the third valve position, the inlet pipe section 02, the bypass pipe section 06, and the discharge pipe section 04 are connected and the main pipeline is connected. The opening degree of the third valve is the third opening degree. Among them, the third opening degree is between the first opening degree and the second opening degree.

The third opening degree may be one, or more than two, which can be selected according to actual needs. Preferably, the third opening degrees are more than two, so that when the gas temperature of the intercooler is not less than the first preset temperature and less than the second preset temperature, the second controller can further adjust the gas temperature of the intercooler The opening degree of the third valve is adjusted to adjust the flow rate of the cooling medium flowing through the bypass pipe section 06.

For ease of control, the first valve 05, the second valve 07, and the third valve are solenoid valves. Of course, the first valve 05, the second valve 07, and the third valve can also be selected as other valves, which are not limited thereto.
