Description of the drawings
Invention is described further using attached drawing, but the embodiment in attached drawing does not constitute any limitation of the invention,
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to the following drawings
Its attached drawing.
Fig. 1 is a kind of structural schematic diagram of the heat pipe of annular anti-gravity of the present invention.
Fig. 2 is a kind of operating diagram of the heat pipe of annular anti-gravity of the present invention.
Include in figure：
Magnetic fluid 1, influent stream pipeline 2, coil 3, fever section 4, pyrotoxin 5, reflux line 6, cooler 7.
Specific implementation mode
The invention will be further described with the following Examples.
The heat pipe of a kind of annular anti-gravity of the present embodiment, as shown in Figure 1, to form the cooling of annular including being connected to end
Device 7, influent stream pipeline 2, fever section 4 and reflux line 6, wherein fever section 4 is in the top of cooler 7, influent stream pipeline 2 and return duct
Road 6 is wound with coil 3 in the both sides of fever section 4 and cooler 7, the outer surface of influent stream pipeline 2, and the coil 3 and direct current are electrically connected
It connects, the working medium that 7 the inside of the cooler is filled is magnetic fluid 1.
Entire annular antigravity heat pipe is by this four major part of cooler 7, influent stream pipeline 2, fever section 4 and reflux line 6
It is welded.It is no any wick structure in the cavity of heat pipe.Heat pipe is made by red copper, corrosion-resistant, high temperature resistant.
It is filled with magnetic fluid 1 after being vacuumized in the cavity of opposite heat tube and is used as working medium, when coil 3 leads to direct current, influent stream pipeline 2
Inside just there is the magnetic field opposite with gravity direction, makes magnetic fluid 1 from cooler 7s, into influent stream pipeline 2, then flow into fever
Section 4, when this fever section 4 with u-tube structure is full of magnetic fluid 1, magnetic fluid 1 is just because of the effect in magnetic field and itself weight
Power finally returns to cooler 7 into reflux line 6.Wherein pyrotoxin 5 transmits heat to fever section 4, and continually flows
Magnetic fluid 1 constantly take away fever the main heat of section.The effect of temperature is reduced to be reached for pyrotoxin 5.
The fever section 4 with u-tube structure is by the welding box body of the U-tube and a long Boping template of both sides
Made of.
The volume of cooler 7 will be made than the total measurement (volume) of influent stream pipeline 2, fever section 4 and 6 this three of reflux line more
Greatly.Magnetic fluid 1 fills up cooler 7.This so that before the magnetic fluid 1 in reflux line 6 does not also return to cooler 7, cooler 7 is also
Magnetic fluid 1 can be supplied toward influent stream pipeline 2.Magnetic is lost suddenly when can avoid 1 temperature rise of magnetic fluid as possible to curie point simultaneously
The phenomenon that property.
Sufficiently large direct current is needed in the coil 3 curled outside influent stream pipeline 2, coincidence formulaWherein a is the acceleration that magnetic fluid rises in flowing into pipeline,
G is acceleration of gravity 9.8m/s2, r is the radius of flowing into pipeline, and n is the coil turn for being wrapped in flowing into pipeline, and u is magnetic conductivity,
It is 1 in the present embodiment magnetic conductivity so that magnetic fluid 1 is because the effect of magnetic field force can overcome gravity in a kind of annular antigravity heat pipe
Interior flowing.
Compared with previous heat pipe, the heat pipe of the present embodiment has the following advantages：
(1) under the action of a magnetic force, can there is no the case where capillary wick, worked normally under conditions of anti-gravity,
The problems such as this structure can overcome capillary wick difficult arrangement, and capillary wick is insufficient.
(2) volume of cooler is big, and when temperature rise to the curie point that can avoid magnetic fluid 1 as possible loses magnetism suddenly
The phenomenon that.
(3) magnetic fluid 1 can constantly be flowed as working medium in a kind of annular antigravity heat pipe, to constantly take away
The heat of pyrotoxin 5.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than the present invention is protected
The limitation of range is protected, although being explained in detail to the present invention with reference to preferred embodiment, those skilled in the art answer
Work as understanding, technical scheme of the present invention can be modified or replaced equivalently, without departing from the reality of technical solution of the present invention
Matter and range.
