The device for realizing the method is also disclosed.
Description
Technical field
The present invention relates to a kind of method of removing and device of not concretive gas inside heat pipe, relate in particular to a kind of heat pipe in degassing procedure, utilize pressure differential to reach the method for eliminating not concretive gas and the device that described method is directly used.
Background technology
Because characteristics such as heat pipe has that heat-transfer capability is strong, heat transfer rate is fast, pyroconductivity is high, in light weight, no mobile component, simple in structure and purposes are many are so can conduct heat and not consume electric power in a large number, the radiating requirements of very suitable electronic product.In addition, known heat pipe inwall all is provided with capillary structure (wick structure), described capillary structure can be has capillary mesh grid etc., utilizes the capillarity of capillary structure, can make things convenient for the transmission of working fluid (working fluid) in the heat pipe.
Prior art is when making heat pipe, the vapor stream that sprays with the heating method of displacing is driven the not concretive gas (non-condensing gas) in the heat pipe out of, it is aqueous working fluid that described method is used for normal temperature, and is applicable to the less water of operating personnel's danger coefficient, dichlorodifluoromethan (freon 113), ethanol (ethanol) or the like.Described method is injecting in the heat pipe more than the working fluid of enclosed volume slightly, the exhaust outlet of temporary transient locking heat pipe upper end, and opposite heat tube heating, make steam pressure as working fluids such as water at 0.11～0.4Mpa, greater than the saturation pressure of working fluid, then, the heat pipe exhaust outlet that will temporarily lock again is open, make the inside and outside pressure balance of heat pipe, working fluid begins the exhaust outlet ejection steam from heat pipe.Flickering is a kind ofly to evaporate into the physical phenomenon (the rapid gasification of saturation water) of gas phase by liquid phase moment, and the gas during this flickering makes working fluid and is dissolved in described fluid separates, and the vapor stream of ejection is driven the not concretive gas in the heat pipe out of.After discharging suitable steam, the exhaust outlet of sealing heat pipe can fully be discharged not concretive gas in the described heat pipe; And the amount of working fluid of enclosing is the poor of the working fluid of excessive inclosure in advance and Fluid Volume that steam is driven out of, and this must obtain the amount of displacing in advance according to heat time heating time, temperature and heat pipe shape.
In described method, utilize the exhaust outlet of the temporary transient locking of heat pipe to come the closed steam fluid earlier, to the steam pressure of working fluid enough after, again the exhaust outlet of described temporary transient locking is decontroled, not concretive gas is driven out of by steam, but the action of locking, open row gas port so repeatedly can make sealing part harden because of excessive machining, and the quality that consequently influences heat pipe reaches thereafter to be used.
As from the foregoing, the known method that is applied to discharge not concretive gas inside heat pipe on reality is used, obviously has defective, can wait to be improved.
Because the defective that exists in the above-mentioned known technology, the inventor relies on and to be engaged in the sector experience for many years, concentrates on studies and cooperates actual utilization, in line with excelsior spirit, active research improvement proposes a kind of reasonable in design and effectively improve the present invention of above-mentioned defective finally.
Content of the present invention
Main purpose of the present invention, be to provide a kind of method of removing and device of not concretive gas inside heat pipe, it can make tube body of heat pipe in the exhaust process of carrying out not concretive gas, need not change its mouth of pipe bore and shape thereof, also can control the discharge rate of not concretive gas easily, thus the structural quality that can effectively improve the heat pipe amount of sealing up for safekeeping and seal.
In order to realize described purpose, the invention provides a kind of method of removing of not concretive gas inside heat pipe, its key step is as follows: reserve exhaust outlet a) at the inner working fluid of filling of the body of heat pipe, and in described body upper end; B) be pressed on the exhaust outlet of described body with cushion; C) to the heating of described body, to described body pressure inside greater than described cushion compress power the time, the steam of described body inside is pushed described cushion open and is discharged by exhaust outlet, discharges not concretive gas simultaneously; When d) working fluid for the treatment of described body inside arrives predetermined steam discharge rate or efflux time, seal the exhaust outlet of described body.
In order to realize described purpose, the invention provides a kind of device of removing of not concretive gas inside heat pipe, itself and a tube body of heat pipe cooperating comprise that at least one heating tool, seals a unit and a cushion.Wherein, described heating tool is used for to described body heating, and is provided with folder portion, with described body location; The described unit that seals then is located at described heating tool top, the peripheral side edge that promptly described body seals, and the enclosed mechanism that comprises the Sealing pliers mould and make the opening and closing mould for described Sealing pliers mould; Described cushion is pressed on described body and seals.The device of removing of forming a not concretive gas inside heat pipe thus.
The invention has the advantages that:
1, in degassing procedure, the exhaust outlet 101 of the body 10 of heat pipe 1 need not be out of shape (the temporary transient locking of known technology palpus exhaust outlet, and make its caliber size and alteration of form), so the discharge rate of not concretive gas is controlled easily, and it is utilize cushion 40 can be easy in degassing procedure the internal pressure of the body 10 of control heat pipe 1, and comparatively stable.
2, can utilize the simple described device of structure to cooperate and carry out, described device can cooperate the demand of the body 10 of different tube diameters after modular design.
3, sealing part is because of the not action of the temporary transient locking exhaust outlet 101 of opening and closing mould repeatedly, so the enclosuring structure of exhaust outlet 101 can not harden because of excessively processing.
