Open and be described in further detail.
Fig. 1 show the principle of the embodiment using the high temperature resistant conductance type liquid metal electromagnetic pump 100 according to the disclosure
Structural representation.As shown in figure 1, electromagnetic pump 100 is arranged in shell 170, including electric insulation pump core 110, it has straight-through pump
The import and export 140 of chamber 120 and longitudinally connected liquid metal pipeline.Magnet or magnet array 130 are along the import and export 140 with pump core
Longitudinally perpendicular direction be arranged in pump core opposite side.Specifically, i.e., Fig. 1 paper inward-outward direction both sides along
The horizontal direction arrangement of pump core 110.The pump core in the direction vertical with paired magnet array arranged direction both sides (such as figure it is upper
Lower both sides) a pair of electrodes 150 is set.
Shown in Fig. 2 is the sectional view of the embodiment of the electromagnetic pump according to the disclosure.As shown in Fig. 2 paired electrode 150 is worn
110 liang of side through hole of pump core are crossed to be powered to the liquid metal in pump chamber.Thermal insulation layer 180 is disposed between pump core 110 and magnet 130.
The heat that the interior liquid metal of pump chamber 12 passes to magnet 130 can be reduced or eliminated by thermal insulation layer 180.Thermal insulation layer 180 can
To be air layer, heat-barrier material part or vacuum insulation panel.The magnetic of magnet would generally be varied from temperature inversion.Especially
When at high temperature, more than Curie temperature (the Curie Temperature) of magnet, magnet can also lose magnetism.Therefore using every
Thermosphere 180 prevents influence of the heat of high temperature of liquid metal in pump chamber to magnet magnetic to be just highly desirable to.
In order to further reduce influence of the high temperature to the magnetic of magnet, also set according to the electromagnetic pump 100 of the disclosure for magnet
Air-cooled fan 160 has been put (referring to Fig. 1).By air-cooled fan, the temperature of magnet can be further kept, so as to keep high temperature
The magnetic field intensity of liquid metal electromagnetic pump provides further guarantee.

130-1,130-2 and 130-3, are encapsulated in a magnet shell 135 to be fixed to one another.Arrow in Fig. 3 represents magnet
Magnetic pole it is reverse.Positioned at center magnet 130-2 N extreme directions face pump chamber, and with the lower magnet of the opposite side of pump chamber 120
The S of center magnet 130-5 in array 130-4,130-5 and 130-6 is extremely relative, forms the magnetic confining field through pump chamber 120.
And the magnet 130-1 and 130-3 of the both sides in upper magnet array 130 N extreme directions face center magnet 130-2 both sides.
Equally, the magnet 130-4 and 130-6 of the both sides in lower magnet array 130 S extreme directions face the two of center magnet 130-2
Side.This arrangement mode will extrude the magnetic field of center magnet by the paired magnet of the both sides of magnet array so that paired magnetic
A pair of magnet that the central magnetic field strength ratio of the magnetic confining field of body 130-2 and 130-5 formation is simple improves 35%~50%, together
When cause fringe magnetic field intensity to keep essentially identical with central magnetic field intensity.Thus more preferable uniform magnetic field is obtained in pump chamber,
So as to obtain the liquid metal flow velocity and flow of stable and bigger lift.In addition, can also further be dropped using adiabatic object 135
Influence of the high temperature fluent metal to the magnetic of magnet in low pump chamber.
Shown in Fig. 4 is another example schematic of the arrangement mode of the magnet array of the electromagnetic pump according to the disclosure.
As shown in figure 4, the arrangement mode difference having shown in Fig. 3 of the arrangement mode is upper and lower part magnet array in centre
The front and rear sides of magnet add a magnet respectively, so that top magnet array and lower magnet array formation cross magnetic
Volume array.Equally, top magnet array former and later two increased magnets N poles also face center magnet front and rear sides；And
Lower magnet array former and later two increased magnets S poles also face center magnet front and rear sides.Equally, in Fig. 4, arrow
Head represents magnet poles direction, and " X " also illustrates that the magnetic pole N poles of center magnet are pointed to and "●" also illustrates that magnetic in the middle of bottom
The sensing of the magnetic pole S poles of body.In order to become apparent from showing the arrangement mode, shown in Fig. 5 is the magnet array arrangement side shown in Fig. 4
The schematic top plan view of the top magnet array of formula, and the lower magnet battle array of the magnet array arrangement mode shown in Fig. 4 shown in Fig. 6
The schematic top plan view of row.This cross-shaped arrangement mode is further squeezed from both direction to the magnetic field in pump chamber region
Pressure so that the central magnetic field intensity of the magnetic confining field of paired magnet 130-2 and 130-5 formation is further improved, and is thus made
The magnetic field for obtaining pump chamber region is more uniformly distributed, while so that fringe magnetic field intensity keeps further convergent with central magnetic field intensity.
Although only describing two kinds of magnet arrays 130 herein, its arrangement mode can increase M shape arrangement side
Formula or other the arrangement mode of similar arrangement is carried out around center magnet, can equally be carried with the fringe magnetic field in extruding center magnetic field
High central magnetic field intensity and the uniformity of fringe magnetic field.
Referring back to Fig. 1, the inner surface of pump chamber 120 and through-hole inner surface are coated with heat-resisting and heat insulating coat, by
This heat for further having separated the high temperature fluent metal in sheet strong 120 is transmitted to external magnets.The refractory coating can be
Heat resisting temperature is higher than 600 DEG C of ceramic coating.It should be noted that between the through hole and electrode of pump chamber 130 and passing in and out
Mouth joint is sealed using high-temperature seal adhesive, with prevent leakage.In addition it is convenient in order to be coated with heat-insulated figure layer, pump core can be caused
110 are made up of two panels up and down multiple bolt fasteners or the fastening of other fasteners.The EDGE CONTACT portion of two panels above and below so
Divide and bolt fastening position is sealed using high-temperature seal adhesive.
Understand according to the above description, the high temperature resistant liquid metal electromagnetic pump of the disclosure had both adapted to high temperature heat dissipation environment or can
It is enough to obtain the magnetic field for carrying out the big lift of big flow.
Above-mentioned embodiment, does not constitute the limitation to disclosure protection domain.Those skilled in the art should be bright
It is white, depending on design requirement and other factors, can occur various modifications, combination, sub-portfolio and replacement.It is any
Modifications, equivalent substitutions and improvements made within the spirit and principle of the disclosure etc., should be included in disclosure protection domain
Within.
