Connected by the storage battery of independent controller and new-energy automobile, the Working mould of compression cylinder 6 is controlled using storage battery power-supply controller
Formula.For whole automotive air-conditioning system, compressor of air conditioner of the invention only changes the mode of operation of compressor, and to originally
The all parts of automotive air-conditioning system do not have much changes.
When controlling switch 4 is powered and coil 3 is constantly carried out forward and reverse energization, the mover iron of piston role is served as
Core 2 can constantly do linear reciprocating motion and cylinder 7 is compressed therewith.Cooling energy-efficient collection magnetic control is compressed to straight
When line motor is in holding state, mover iron core 2 is in the position shown in Fig. 1.Positive be powered of coil 3 causes the institute of mover iron core 2
N, S pole of generation.When coil 3 is powered by the way that controlling switch 4 is positive, mover iron core 2 will be rapid by magnetic field force forward
The position shown in Fig. 2 is moved to be compressed cylinder 7；When coil 3 is reversely powered by controlling switch 4, mover iron core 2
Opposite magnetic field will be produced, the magnetic field force being subject to also can be on the contrary, i.e. mover iron core 2 can be moved to such as that the former of Fig. 1 (can in position
Observed by the dotted line in figure, line on the basis of dotted line).So constantly circulation, mover iron core 2 just can constantly do back and forth reciprocal straight
Line motion (compression and refrigeration).
It is integrated with compression refrigerating apparatus that present embodiment realizes power by collecting magnetic control to greatest extent to technology, no
But complicated brace and connecting rod framework can be saved, the intermediate consumption of electric energy is reduced, backing field lengthened piston stroke can also be passed through
Mode increase substantially the operational efficiency of mechanical system so that the thrust of " piston " becomes more strong in energy saving
Greatly；And overall weight and volume is all changed, volume is smaller, and weight is lighter, and the occasion so used is also just wider
It is general.
Stator magnetic tube 1 can also use single-layer mode in the present invention, but the stator magnetic tube 1 of single-layer mode is limited
Thrust and acceleration obtained by the stroke of mover iron core 2, mover iron core 2 is also undesirable.Increase the thickness or length of stator magnetic tube 1
Although degree can make the magnetic field-enhanced of magnetic tube two ends, effective rectilinear path (unidirectional) of mover iron core 2 is not carried significantly
Height, so crucial be just make mover iron core 2 have satisfied stroke using the stator magnetic tube 1 of terraced fields shape layer structure, push away
Power and acceleration.
As fully visible, during the entire process of thrust output, the control of input current is very pure --- only it is embodied in
The through and off of circuit.In other words, one begin " logical ", it is enough for the simple motion of only " disconnected ".In other words, " logical " is being begun --- only
In " disconnected " this section of stroke, input current is " permanent steady ".The operating current how it feels of " permanent steady "Mean to have realized stroke
Traditional control, modern scientist, intelligent control are gone in control.In short, going technical sophistication.
It should be noted that the above-mentioned case parameter being related to is only used for stating the reality of embodiment, not representative products
Data.In addition, above-described embodiment is only statement embodiments of the present invention, the practical range of the present invention is not limited with this, therefore
All equivalence changes made according to the shape of the present invention, construction and principle, are covered by within protection scope of the present invention.
