Abstract
The invention relates to a suspending magnet cooling method of low-speed magnetic suspension vehicle. It is characterized in that: the heat pipe adsorbs the heat generated by magnet, to be transmitted to the condenser to emit heat. And the invention can realize effective cooling, when the magnetic suspension magnet coils are increased.
Description
Technical field:
The invention relates to cooling, particularly about the suspension magnet cooling means and the device thereof of low speed magnetic floating vehicle.
Background technology:
The advantage day that speed per hour about magnetic floating traffic not only has up to 500 kilometers, especially its stable, no air pollution, noiseless are disturbed shows outstanding, is gradually paid close attention to by Urban Transportation department.Recently speed per hour is being studied below 200 kilometers by states such as U.S., day, is adapted to the low speed magnetic floating traffic that transport point needs in the city scope.
Low speed (city rail) magnetic-levitation train that is driven by line inductance electromotor relies on vehicle-mounted suspension magnet to produce suspending power, satisfies train carrying demand.The magnetic thrust driving that vehicle is interacted and produced by line inductance electromotor and aluminium tablet.
HSST (High Speed Surface Transfortation) magnetic-levitation train technology with reference to US5152227, the both sides of rail beam are F shape steel ferromagnetism track, suspension (guiding of the holding concurrently) electromagnet that is fixed on the magnetic-levitation train body just in time places the track below, and iron core is positive U-shaped, and is relative with F rail road.In onboard power system when energising,, the electromagnetic attraction between electromagnet and the track produces enough vehicle passenger carrying capacities, is installed in the gap sensor real-time detection electromagnet between the adjacent electromagnet and the spacing of track simultaneously.By reconciling the exciting current of electromagnet, adjust the gravitation between electromagnet and the track, be stabilized in about 8.0mm to keep the gap between electromagnet and the track, and can be under the measurement of range finding probe the electric current of the magnet coil of continuous control vehicle.
When the train disalignment, the iron core of U-shaped electromagnet and the dislocation of F shape track, gravitation between the two tilts, and produces a cross stream component opposite with offset direction, makes train return center line.That is to say that the guiding of HSST magnetic-levitation train is automatically, does not need the ACTIVE CONTROL of guiding electromagnet.But have the suspending power deficiency, passenger carrying capacity is limited.。
Japan confirms that through long term studies and demonstration the feasibility of this technology with advanced, has the commercial value of using, can be practical in urban track traffic.Suspension magnet structure with the JP62-210807 patent is an example, though proposed the scheme of air-cooled suspension magnet coil, effect is undesirable.But the suspending power of low speed (city rail) maglev vehicle is restricted at present, can't satisfy big demand of passenger transport.The structures shape of suspension magnet coil the current limit and the number of turn, thereby define suspending power.As require to improve with the suspending power that satisfies moment by big electric current in coil, will certainly bring coil overheated.As will improving the suspending power of suspension magnet, improve the passenger carrying capacity of train, the problem that is faced is: magnetic close saturated, the suspension magnet coil is overheated.Through nearly 20 years research, all fail to solve the suspension magnet problems of excessive heat.
Summary of the invention:
The suspension magnet cooling means and the device thereof that the purpose of this invention is to provide a kind of low speed magnetic floating vehicle, for the suspension magnet coil that solves low speed (city rail) maglev vehicle under the operating mode that increases number of ampere turns, how to realize the effectively technical problem of cooling.The technical scheme that the present invention solves the problems of the technologies described above is:
A kind of suspension magnet cooling means of low speed magnetic floating vehicle is characterized in that: by heat pipe with the heat absorption that suspension magnet produced after, conduct to condenser heat radiation.
It is characterized in that: with the interior liquid that fills is heat-conducting medium.

The present invention has following technical characterstic:
1) adopts the direct cooling means of pole core, improved the suspending power of suspension magnet.
2) can with the supporting use of existing (city rail) magnetic-levitation train.
3) utilize existing ripe concentrated condenser and heat pipe conduction technique, use cooling effect reliable and stable.
4) directly cooling off under the operating mode, the suspending power of low speed (city rail) maglev vehicle is because the moment number of ampere turns raising and the obviously enhancing of suspension magnet coil.
5) available pure distilled water is reduced expenses pollution-free again public hazards as the medium that transmit heat.
6) concentrate condenser to be suspended on the outside of bogie, directly flowing with the train operation air contacts, and strengthens cooling effect.
7) this cooling means is one of key technology of low speed (city rail) maglev vehicle design.

The specific embodiment:
As shown in Figure 1, the external air-conditioning 1-1 of compartment 1, train that installs on bogie 6, seat 1-2, vehicle window 1-3, horizontal device for moving and adjusting 2, air spring 3, linear electric motors 5, suspension magnet 7 all are parts of train suspension load.And skid 9 when only bearing train and stopping to the support of vehicle.F shape magnetic orbit 10 is to transmit the interface of train load to rail beam 12.Transverse sleeper 11 conducts are the parts of F shape magnetic orbit 10 fixedly.In order to realize the raising of suspending power, require to increase the electric current of suspension magnet 7 coils, it is overheated to relate to, and need the iron core of suspension magnet 7 be cooled off.
The present invention runs through heat pipe 7-1 (referring to Fig. 2) is installed in the iron core of suspension magnet 7, utilizes fixedly water conservancy diversion metal tube 8 of attaching nut 7-2.This water conservancy diversion metal tube 8 is connected on the interface nut 4-2 of condenser 4.And condenser 4 is fixed with the outside of bogie 6 by hanging screw fixture 4-3 (referring to Fig. 3).Each suspension magnet 7 is provided with several heat pipes 7-1, and condenser 4 is to concentrate condenser, the two ends of each heat pipe 7-1 join with corresponding water conservancy diversion metal tube 8 with hold-down nut respectively, and above-mentioned each water conservancy diversion metal tube 8 then is connected with concentrated condenser 4 with interface nut 4-2 respectively.
When normal operation of train and parking, the heat Q1 that the coil of suspension magnet 7 produces diffuses to the liquid (for example distilled water, alcohol, volatility wet goods) in the core interior heat pipe 7-1, make its boiling, overheated liquid can transmit heat in the condenser 4, the liquid that (dissipates heat Q2) and form the state of cooling after supercooling flow back into the heat pipe 7-1 in the iron core once more, sees Fig. 4.Form the circulation state of cooling thus, reach the cooling effect of suspension magnet.
Must there be good sealing device each junction of the present invention, to avoid the liquid outer-flowing phenomenon.The inspection of cooling fluid should be carried out in practical back (six months～a year) through the long period, guarantees cooling effect.
