What the present invention was realized in：A kind of underbody backplate of integrated gate-controlled switch structure, the underbody backplate are starting
Region corresponding to cabin offers some ventilating openings, and the sealing plate that opening and closing is controlled by controller is housed on the ventilating opening.
A kind of control method of the underbody backplate of integrated gate-controlled switch structure, setting and temperature threshold T1 and two level temperature
Threshold value T2, using sealing plate by the aperture that ventilating opening completely closes as 0, aperture when being opened to maximum position using sealing plate as
100%, controller selects the aperture of control sealing plate according to following situation；T is enging cabin observed temperature；
1) when vehicle is in flameout state,
Such as T >=T1, then controller control sealing plate is opened to maximum opening, i.e. aperture 100%；
Such as T ＜ T1, the then closing of controller control sealing plate, i.e. aperture 0；
2) when vehicle is in driving states,
Such as T >=T1, then controller control sealing plate is opened to maximum opening, i.e. aperture 100%；
Such as T≤T2, the then closing of controller control sealing plate, i.e. aperture 0；
Such as T2 ＜ T ＜ T1, then controller is according to f（T）Control the aperture of sealing plate 4, f（T）Obtained according to experiment.
The vehicle power-off is considered as flameout state, and remaining is then considered as driving states.
The step of also including setting speed threshold value V1, as vehicle current vehicle speed V >=speed threshold value V1, do not start to sealing
The control of plate, the sealing plate are maintained at the full-shut position that initial aperture is 0.
The speed threshold value is emulated by CFD or the method for real train test, determines vehicle operationally, enging cabin wind
Flow and heat flux in the case of fanning not open in enging cabin determines speed threshold value V1.
Also include setting opening time S, when the vehicle is in flameout state and T >=T1, the controller control sealing
Plate is opened to after 100% aperture is kept for the S times and closes sealing plate.
The opening time S is 30 seconds.
The f（T）Specific test method be by sealing plate standard-sized sheet and fully closed to obtain pole respectively under identical test operating mode
Engine compartment temperature under the conditions of limit, sealing plate aperture is then divided into several pieces, carries out testing under each aperture respectively
Engine compartment temperature, engine compartment temperature T function fs corresponding with sealing plate aperture is obtained finally by fitting（T）.
The underbody backplate and control method of the integrated gate-controlled switch structure of the present invention are under some special operation conditions, such as vehicle puts out
Ventilating opening can be opened in short time after fire and helps radiating of engine cabin, prevents part aging, improves making for parts in cabin
Use the life-span；Ventilating opening can be also controlled according to actual conditions in way of driving a vehicle, there is provided heat dissipation channel, and engine can be reduced
Requirement of the part to heat resistance in cabin, reduce integral vehicle cost；In addition, when coordinating cooling with cooling fan associated working, can subtract
Few cooling fan working time, and then improve noise figure, improve user's comfortableness.
