Sky, vacuum meter is used to observe the size of vacuum；Fluid injection part is made up of syringe, capillary, and liquid is injected by syringe
In flat-plate type micro heat pipe；Vacuumize the same hole that hole and liquid injection hole are shared on flat-plate type micro heat pipe；Vacuumize with injection process, by
Hand-operated valve controls the connection of flat-plate type micro heat pipe and each part.
The vacuum that the vavuum pump is vacuumized to flat-plate type micro heat pipe is 10-1~10-3Pa。
The volume of the gas bottle is 100mL.
The syringe range is 2.5mL, and precision is 0.1mL.
The nipple of the syringe is attached with capillary.
The internal diameter of the capillary is 1.5mm.
Connection between the capillary and each part is interference fit, to ensure the air-tightness of device.
Operation principle of the invention mainly has three below aspect：1st, rear fluid injection is first vacuumized, hole and liquid injection hole is vacuumized
The same hole on flat-plate type micro heat pipe is shared, the connection of flat-plate type micro heat pipe and each part is controlled by hand-operated valve, it is true hence into taking out
Empty or injection process；2nd, in vacuum, gas bottle is connected with flat-plate type micro heat pipe, it is to avoid directly flat-plate type micro heat pipe is carried out
Vacuumize and cause larger error；3rd, rear plate micro heat pipe vapor cavity is vacuumized for vacuum state, is existed with the external world larger
Pressure differential, thus atmospheric pressure can the automatic liquid whole injection flat-plate type micro heat pipe vapor cavity by syringe.
The beneficial effects of the present invention are：1st, the same hole that hole and liquid injection hole are shared on flat-plate type micro heat pipe is vacuumized, is subtracted
Small fabrication error；2nd, gas bottle is used, it is to avoid directly flat-plate type micro heat pipe is vacuumized and larger error is caused, it is ensured that vacuum
Degree is required；3rd, using pressure differential, the automatic accurate injection of liquid is realized；4th, apparatus of the present invention simple structure, with low cost, operation
Reliable, vacuum and reservoir quantity are accurate.
