The specific embodiment
With reference to Figure of description 1, it shows a kind of water-base nano fluid and integration apparatus of filling heat pipe of preparing, and its basic structure is that it comprises:
First metering device, the nano powder that metering predeterminable quantity is given;
Mixed stirring device connects said metering device, to admit said nano powder and the basic liquid refrigerant mixing and stirring good with proportioning, obtains mixed once liquid;
The after-treatment device connects said mixed stirring device admitting said mixed once liquid, and then further handles, and nano powder further all is dispersed in the basic liquid refrigerant, obtains the secondary mixed liquor;
Second metering device connects said after-treatment device to admit the said secondary mixed liquor of set amount, and this second metering device connects heat pipe to be filled through control valve and pipeline;

Heater, the heater that heat pipe to be filled is heated can adopt electric furnace heating wire heating furnace or heat exchanger to accomplish, and flows through the electric current of electric furnace heating wire and the flow of voltage or heat exchanger is controlled its heating power through control.The both has reasonable controllability, mainly through thermal exhaust, is used for obtaining higher vacuum.
Mate, need the configuration temperature-detecting device under the necessary situation,,, prevent that heat pipe is because of the quenching explosion to guarantee in the security of heated condition and the security of perfusion fluid to detect heat pipe to be filled at the heated temperatures state.
Temperature-detecting device forms a kind of peripheral checkout equipment; With the feedback of status of each link that is used to circulate, to control more accurately, further; Peripheral checkout equipment preferably includes: detect the checkout gear whether metering device reaches setting value, such as weighing mechanism; Detect nano suspending liquid and whether be transported in the suspension container 8, detect nano-fluid and whether be transported to gauge line 12, can adopt the device of flowmeter or sense weight; Detect gauge line vacuum and whether reach upper limit requirement, detect heat pipe 16 vacuums and whether reach the lower limit requirement, just detect through vacuum meter; Detect heat pipe 16 and whether cool off, just adopt temperature-detecting device above-mentioned; Detect the nano-fluid value and whether reach setting value, can adopt weight detecting; Detect heat pipe 16 top topping up pipes and whether seal, hunt leak through leak test plant.
About vacuum meter 18, the desirable upper limit can be set to 1.3～0.13Pa, and lower limit is set to 1.33 * 10
-3Pa.
Sealing device 20 can adopt the hydraulic pressure sealing tech, also can adopt the electronic seal technology.
The effect of vavuum pump 19 is that opposite heat tube vacuumizes, and guarantee to be in the heat pipe vacuum state.Controller is started working, and carries out FEEDFORWARD CONTROL, opens control valve 2, and the certain amount of nano particle is added to the deionized water container 4 from storage container 1 through metering device 3.Closed control valve 2; After controller startup magnetic stirring apparatus 5 carries out the magnetic agitation certain hour; Controller opens power set 6 and control valve 7 are transported to the nano suspending liquid after stirring in the suspension container 8, and controller starts ultrasonic vibration installation 9; Ultrasonic vibration suspension container 8 certain hours make that the suspension of nano-fluid is uniform and stable.Controller is opened power set 10 and control valve 11 again, the nano-fluid for preparing is transported to gauge line 12 after, controller closed control valve 11 is opened control valve 13, starts vavuum pump 19, and gauge line is carried out vacuum degassing.When vacuum reached requiring of the upper limit, controller closed control valve 13 was opened control valve 17 opposite heat tubes 16 and is vacuumized, and started heating furnace 15 and carry out heat pipe 16 bake outs, treated that heat pipe 16 vacuums reach the requirement of lower limit, stopped heating; After heat pipe 16 coolings, controller closed control valve 17 is opened control valve 14; The certain amount of nano fluid will flow in the heat pipe automatically; Equivalent value reaches predetermined being provided with when requiring, closed control valve 14, and controller starts sealing device 20; The top topping up pipe of heat pipe 16 is sealed, accomplished the integrated process of whole nano-fluid making and heat pipe topping up.
