Description of drawings
Below in conjunction with accompanying drawing the utility model is done further to detail.
Fig. 1 is the structural representation of the utility model.
Each label is among the figure: 1, proportion magnetic valve; 2, return pipe; 3, draft tube; 4, electronic control unit; 5, bypass retaining valve; 6, water inlet retaining valve; 7, water inlet pipe; 8, air temperature sensor; 9, gas outlet; 10, the empty heat exchanger of water; 11, water circulating pump; 12, by-pass pipe.
Embodiment
Referring to Fig. 1, this device comprises cooling device and control device
1) cooling device comprises: the empty heat exchanger 10 of water, water circulating pump 11, bypass retaining valve 5, water inlet retaining valve 6.Water circulating pump 11 drives recirculated water and in pipeline, flows; Water inlet retaining valve 6, bypass retaining valve 5 are used for the flow direction of Control Circulation water; Recirculated water carries out heat interchange in the empty heat exchanger 10 of water and from the high temperature air of turbosupercharger; Take away the heat of high temperature air, thereby the intake air temperature of control engine guarantees that the engine test data are accurate.
2) control device comprises: air temperature sensor 8, electronic control unit 4 and proportion magnetic valve 1.Air temperature sensor 8 is used to gather cooled air themperature; And the air temperature signal that collects delivered to electronic control unit 4; Calculate the opening angle of proportion magnetic valve 1 according to cooled air themperature value by electronic control unit 4; And drive signal sent to proportion magnetic valve 1, the flow of passing ratio solenoid valve 1 Control Circulation water.
Principle of work:
The high-temperature gas that comes out from engine supercharger gets into the empty heat exchanger 10 of water by draft tube 3; Cooling circulating water gets into cooling device through water inlet pipe 7; The retaining valve 6 of will intaking is opened, and water circulating pump 11 drives recirculated water and in cooling line, circulates, and increases the flow velocity and the pressure of recirculated water.Be recycled water behind the empty heat exchanger 10 of high temperature air process water and take away unnecessary heat; Its temperature reduces; Air temperature sensor 8 is measured cooled air themperature in real time, and feeds back to electronic control unit 4 to the temperature signal that collects in real time, and electronic control unit 4 calculates the opening angle of proportion magnetic valve 1 in real time; Thereby the flow of accurate Control Circulation water, and then accurately control cooled air themperature.
When cooled air themperature is higher or lower than setting value; The calculated signals that electronic control unit 4 comes according to air temperature sensor 8 feedbacks goes out the aperture of proportion magnetic valve 1; Proportion magnetic valve is realized the accurate control of air themperature according to the order adjustment aperture of electronic control unit.
When control accuracy is in ± 1.5 ℃ of scopes; Proportion magnetic valve 1 is closed the angle of appointment according to the order of electronic control unit 4; Recirculated water carries out inner partial circulating with constant flow rate through water circulating pump 11, bypass retaining valve 5 and the empty heat exchanger 10 of water, the control accuracy of Engine Inlet Temperature is remained on ± 1.5 ℃ scope in.
