Accompanying drawing is the structural representation of heat pipe of the present invention.
The specific embodiment
The weave heat pipe that nano material fluid working substance is housed of usefulness of the present invention has body 1, end cover 4, capillary wick 2, and sealing end cap 4 is contained in the two ends of body 1, and capillary wick 2 is close on body 1 inwall; It is characterized in that being equipped with in the body 1 immersion ultrasonic transducer 3, the input of this immersion ultrasonic transducer 3 links to each other by the output of cable 6 with body 1 supersonic generator main frame 5 outward; Fluid working substance (not drawing among the figure) is housed in the body 1; Described fluid working substance is made up of deionized water, nano material ZnO, hydrophily dispersant 9D and polyethylene glycol (PEG); The concentration expressed in percentage by weight of nano material ZnO is 1%-1.6%, and the concentration expressed in percentage by weight of hydrophily dispersant 9D is that the concentration expressed in percentage by weight of 0.2%-0.6%, polyethylene glycol (PEG) is 1%-2%.
The present invention adds nano material ZnO in fluid working substance, can improve the heat transfer efficiency of fluid working substance, adds dispersant the particle of nano material ZnO is scatter.When adding dispersant 9D concentration expressed in percentage by weight in 0.2% ~ 0.6% scope, the spacing of nano material ZnO particle increases along with the increase of dispersant concentration, this is because when dispersant concentration expressed in percentage by weight during in 0.2% ~ 0.6% scope, the dispersion dosage that is adsorbed on nano material ZnO surface along with the increase of concentration also increases, strengthened electrostatic repulsion forces between particle, made that nano material ZnO is difficult to reunite.But when the dispersant concentration expressed in percentage by weight greater than 0.6% the time, nano material ZnO grain spacing reduces along with the increase of dispersant concentration in the dispersion liquid, because dispersant 9D is the polyacrylic macromolecule dispersing agent, the macromolecular chain of its certain-length has the steric restriction effect, along with the increase of dispersant in the particle surface adsorbance, steric restriction between the particle also strengthens, and stretches to the mutual tied up in knots of macromolecular chain meeting in the solution, causes nano material ZnO particle agglomeration.
Adding concentration expressed in percentage by weight again and be 1% ~ 2% polyethylene glycol (PEG) can scatter more fully to the particle that nano material ZnO modifies back nano material ZnO.This is because polyethylene glycol (PEG) has modifying function to the surface of nano material ZnO.The hydroxyl on nano material ZnO surface can with the terminal hydroxyl generation etherification reaction of polyethylene glycol (PEG), make polyglycol chain on the nano material ZnO surface grafting; Simultaneously, many oxygen (O) atom is arranged on the polyglycol chain, and these oxygen atoms can form the H key with nano material ZnO, and polyglycol chain just is wrapped in nano material ZnO particle surface like this, increased the steric restriction effect between the particle, it is easy that the dispersion of nano material ZnO also just becomes.Therefore, under the dispersant condition of same concentrations, can scatter more fully with the particle of the nano material ZnO of polyethylene glycol (PEG) modification.
Although the nano material ZnO with polyethylene glycol (PEG) modification has obtained more satisfactory dispersion effect, but, the nano material ZnO agglomeration of some still can take place in fluid working substance work after 11-12 hour, in order to eliminate the agglomeration of nano material ZnO more completely, use ultrasonic wave convection cell working medium to handle, utilize hyperacoustic mechanism, produce powerful mechanical force; Under the effect of this mechanical force, constantly impact nano material ZnO particle, it is fully scatter.The mechanism of action is when connecting the power switch of supersonic generator main frame 5, supersonic generator main frame 5 produces the ultrasonic signal of a 28KHz, this ultrasonic signal sends from the output of supersonic generator main frame 5, flow to the input of immersion transducer 3 by stube cable 6, then immersion transducer 3 sends the ultrasonic wave of 28KHz under the driving of this signal.Because in the heat pipe is high vacuum, so cavitation effect of ultrasonic waves is faint, main is hyperacoustic mechanism.The high-frequency mechanical vibration that is produced by immersion transducer 3 is delivered on the nano material ZnO particle through fluid working substance, kinetic energy is provided for the nano material ZnO particle that is suspended in the fluid, nano material ZnO particle is mutual motion collision under the effect of this energy, nano material ZnO particle is scatter, thereby solved the agglomeration of fluid working substance, improved the stability of work.This ultrasonic frequency is 28KHz, and power is 2W, acts on can the maintaining heat plumber doing there was not tangible agglomeration in tens hours in about 5 minutes.
Because the heat pipe maximum temperature of Weaving device is 90 °, the cable 6 that therefore connects immersion ultrasonic transducer 3 in heat pipe should adopt the cable of high temperature resistant high insulation.Since inside heat pipe be high vacuum be about 1.3 * 10
-1The negative pressure of Pa, so the present invention has done strict seal approach.
Used nano material ZnO is produced by last marine favour nanosecond science and technology Co., Ltd among the present invention, and hydrophily dispersant 9D is produced by nine divisions of China in remote antiquity, Jiangsu chemical industry Co., Ltd, polyethylene glycol (PEG) by Beijing also Haidian fellow member of an association or organization Fine Chemical Works produce.Immersion transducer 3 and supersonic generator main frame 5 include among the TDS-100P type supersonic generator that Shanghai sense brightness electromechanical meters Co., Ltd produces, and circuit is known.
In sum, the present invention has added nano material ZnO in heat-pipe working medium, can improve the heat transfer efficiency of cycle fluid, added dispersant 9D and polyethylene glycol (PEG) in working medium, it is more abundant that nano material ZnO fluid working substance is disperseed.
