By soft logical in succession, also lead in succession by soft between magnetic conduction type main air duct and discharge pipe between described magnetic conduction type main air duct and blast pipe.Softly connect the transmission that can reduce vibration.
Described field power supply and electrode current generator are controlled by control system jointly.Control system be mainly control the startup of this ventilation unit, stop, air intake, air-out, airflow pressure adjustment and other Properties Control.
There is no the mechanical parts such as the motor of conventional blower fan and impeller in the air channel of magnetohydrodynamic ventilation unit of the present invention, but make a kind of brand-new method of ventilation of air movement by the interaction force in electric current in air and magnetic field.
Magnetohydrodynamic ventilation unit of the present invention, its main air duct design external energy is installed superconducting coil, and inner surface is the electrode group, must be smooth and high voltage bearing insulator.The air intake enlarging at main air duct two ends, air-out enlarging are to satisfy air-supply interface needs, and blast pipe, discharge pipe adopt soft connecing with main air duct to be connected.Field power supply and electrode current controller are to be used to provide the device energy.Control system be mainly control the startup of this device, stop, air intake, air-out, airflow pressure adjustment and other Properties Control.
The present invention adopts the rest state operating condition, and vibration and noise are little, need not to be equipped with silencer, efficient, energy-conserving and environment-protective, static equipment, movement-less part, arrangement convenience, simple to operate.
The invention will be further described below in conjunction with the drawings and specific embodiments.
Description of drawings

In figure, 1 is the air intake airflow direction, and 2 is the air intake enlarging, 3 is blast pipe, and 4 are soft connecing, and 5 is superconducting coil, 6 is the electrode group, and 7 is magnetic conduction type main air duct, and 8 is discharge pipe, 9 are the air-out enlarging, 10 are the air-out airflow direction, and 11 is field power supply, and 12 is the electrode current generator, 13 is control system, and 14 is general supply.
The specific embodiment
As shown in Figure 1, magnetohydrodynamic ventilation unit of the present invention comprises magnetic conduction type main air duct 7; On the outer wall of magnetic conduction type main air duct 7, superconducting coil 5 is installed, superconducting coil 5 is connected with field power supply 11; On the inwall of magnetic conduction type main air duct 7, electrode group 6 is installed, electrode group 6 is connected with electrode current generator 12.One end of magnetic conduction type main air duct 7 is equipped with blast pipe 3, on this blast pipe 3 with air intake enlarging 2; The other end of magnetic conduction type main air duct 7 is equipped with discharge pipe 8, on this discharge pipe 8 with air-out enlarging 9.Field power supply 11 is controlled by control system 13 jointly with electrode current generator 12, and general supply 14 provides power supply for control system 13.
Be further to improve performance of the present invention, connect 4 and be communicated with by soft between magnetic conduction type main air duct 7 and blast pipe 3, also connect 4 and be communicated with by soft between magnetic conduction type main air duct 7 and discharge pipe 8.
On magnetic conduction type main air duct 7 of the present invention, superconducting coil 5 and electrode group 6 are installed, superconducting coil 5 is set up powerful magnetic field magnetic conduction type main air duct 7 is interior, electrode group 6 is the air ionization in magnetic conduction type main air duct 7, the current-carrying air will with its perpendicular magnetic field in the effect of electromagnetic force move along the direction of electromagnetic force, push air to right side, air presses in general mood flow path direction 1, through air intake enlarging 2, blast pipe 3, softly connect 4, magnetic conduction type main air duct 7, softly connect 4, discharge pipe 8, air-out enlarging 9, air-out airflow direction 10 goes out, and produces air-flow.In the situation that magnetic field is certain, the larger electromagnetic force of electric current is just larger, and air speed is faster, and the wind speed that causes is just faster; Otherwise electric current is little, and electromagnetic force is little, and thrust is little, and wind speed is also less.Under electromagnetic force, the magnetic conduction type main air duct 7 suffered electromagnetic forces of interior air, and effective volume, current density, the magnetic density of magnetic conduction type main air duct 7 are directly proportional.But the electric current of lower electrode group 6 and the combination of higher magnetic flux density can be raised the efficiency.
When the sense of current in electrode group 6 changed, the direction of electromagnetic force also changed, the ionized air in magnetic conduction type main air duct 7, will with its perpendicular magnetic field in the effect of electromagnetic force move along the direction of electromagnetic force, push air to left side.Airflow direction can be with original opposite.
Can utilize change and regulate size of current and control air quantity, the polarity that changes electrode changes the flow direction.
