Specific embodiment
Invention is further explained with specific embodiment with reference to the accompanying drawings of the specification.
Referring to fig. 2, sodium heat pipe producing device of the invention includes sodium heat pipe 2 to be filled, and the sodium heat pipe 2 is by stainless
Cylindrical body made of steel seals hollow tube, and there is the first nickel tube section 10 and the second nickel tube section 11 to lead to tubular body on top.It is described
First nickel tube section 10 and the second nickel tube section 11 have the pipeline section for protruding into sodium inside heat pipe, wherein the first nickel tube section 10 protrudes into sodium heat pipe
Internal length of pipe section is longer than the length of pipe section that the second nickel tube section 11 protrudes into sodium inside heat pipe.
The outlet of first nickel tube section, the 10 upper end connection, 5 lower end of sodium valves, 5 upper end outlet of sodium valves are connected to sodium by vacuum tube
3 lower end of tank.
The upper end of the second nickel tube section 11 is connected to vacuum tank 8 by vacuum tube, and the vacuum tank 8 is connected by vacuum tube
It is connected to vacuum pump 1, the first vacuum valve 6, the vacuum tank 8 and vacuum pump 1 are set between the second nickel tube section 12 and vacuum tank 8
Between be provided with the second vacuum pump 7.The vacuum tank 8 has hollow volume, and the hollow volume is less than the volume of sodium heat pipe 2.
The vacuum tank 8 is contained in cold trap 9, is had gap between the vacuum tank 8 and cold trap 9, is used in the cold trap 9
In being passed through coolant liquid or cooling gas, cooled down with the outer wall for the vacuum tank 8.Its coolant liquid is preferably liquid nitrogen.
It will be understood by those skilled in the art that " connection " described herein be all by vacuum pipe to various components into
Row connection, and ensure the air-tightness of whole device.In order to improve automatization level, first, second vacuum valve can be used
The opening and closing of the vacuum valve of controllable type, valve body can be controlled by controller or industrial personal computer.
The sodium tank 3 includes the cylindrical body portion on top and the rounding tapering of lower part, and the vertex in rounding tapering is provided with sodium tank
Outlet, the sodium tank outlet are connect by vacuum pipe with sodium valves 5.It is filling do not start when, the sodium in the sodium tank 3 is in solid-state
And be set in the lower space in sodium tank (as shown in Fig. 2 shade), the top of solid-state sodium is vacuum.The tool of the present embodiment design
There is the sodium tank in the cylindrical body portion on top and the rounding tapering of lower part that there is advantage in filling sodium, this structure not only reduces liquid
The resistance of sodium flowing, and reduce sodium in the remnants of sodium top tank structure, ensure the weight of the sodium in sodium heat pipe.
In one embodiment, the production method that the present invention proposes a kind of sodium heat pipe, based on the above embodiment in system
Make device, comprising the following steps:
Step 1: closing sodium valves 5, open the first vacuum valve 6 and the second vacuum valve 7, vacuum pump 1 is opened, in sodium heat pipe 2
It is vacuumized.If obtaining preferable filling effect, the vacuum degree in whole device should be 10-4Below pa.
Step 2: closing the first vacuum valve 6, stay open the second vacuum valve 7, vacuum tank 8 is persistently vacuumized.It is right
Sodium tank 3 is heated, and heating temperature is on the fusing point of sodium, and preferably 120 DEG C, heating time regards the sodium amount in tank, keeps temperature
30 minutes are spent, liquid is molten into all with the sodium for ensureing all.It include simultaneously sodium valves to sodium heat pipe 2 to the pipeline between sodium tank 3
Valve body all heated.The mode that winding resistive heater can be used in above heating carries out, and using temperature measuring equipment to sodium
Tank and pipeline surface carry out temperature measurement, to control the power of heating.
Step 3: sodium valves 5 is opened, so that the liquid sodium in sodium tank 3 closes sodium valves 5 after flowing to sodium heat pipe 2, in the process
The heating to sodium tank 3 and 2 intermediate duct of sodium heat pipe is not stopped, the purpose for the arrangement is that Liquid Sodium is prevented to be condensate in sodium tank 3 and sodium
In 2 intermediate duct of heat pipe.When sodium flows in sodium heat pipe, it can hear that liquid sodium is flowed and dripped in pipeline in sodium heat pipe
Sound, after sound disappears, then kept for a period of time, the sodium to be detained in the sodium and pipeline in sodium tank flows into sodium heat pipe as far as possible
Sodium valves is turned off after in 2.Meanwhile liquid nitrogen is added into cold trap 9, vacuum tank 8 is cooled down, vacuum can also be further decreased
Vacuum degree in tank 8.
Step 4: the first vacuum valve 6 is opened, it is true in vacuum tank 8 since the second vacuum valve 7 is kept it turning in step 2
Reciprocal of duty cycle is higher than sodium heat pipe 2, therefore can generate wink to the pipeline section between the first nickel tube section 10 and sodium tank 3 when the first vacuum valve 6 of unlatching
Between swabbing action, flowed further in sodium heat pipe conducive to sodium remaining in sodium tank 3 and 2 intermediate duct of sodium heat pipe, simultaneously because
The temperature of vacuum tank 8 is substantially less than room temperature, and a small amount of Sodium vapour enters in vacuum tank 8 from the second nickel tube section 11 to be condensate in rapidly
On the inner wall of vacuum tank 8.It is protruded into since the length of pipe section that the first nickel tube section 10 protrudes into sodium inside heat pipe is longer than the second nickel tube section 11
The length of pipe section of sodium inside heat pipe, such setting also prevent Liquid Sodium and enter in the second nickel tube section from the first nickel tube section, into
One stepping enters subsequent pipeline section.
Step 5: close sodium valves 5, entire vacuum line outer wall cooled down, cooling purpose be allow it is remaining in pipeline
Liquid Sodium is all solidified as solid, avoids that Liquid Sodium being pumped into vacuum pump in subsequent vacuum.Cooling mode can
By the way of Temperature fall, air-cooled or liquid cooling.Vacuum pump 1 includes that sodium heat pipe persistently carries out to entire vacuum line during this
It vacuumizes, and keeps vacuum tank 8 to be in low-temperature condition, such as be not parked in cold trap and add liquid nitrogen.
Step 6: closing the first vacuum valve 6, pinch off and encapsulation process are carried out to the first and second nickel tube sections.
Although the detailed description and description of the specific embodiments of the present invention are given above, it should be noted that
We can carry out various equivalent changes and modification to above embodiment according to the concept of the present invention, and generated function is made
It, should all be within protection scope of the present invention when with the spirit still covered without departing from specification and attached drawing.The above, only
Presently preferred embodiments of the present invention is not intended to limit the invention, according to the technical essence of the invention to above embodiments institute
Any trickle amendment, equivalent replacement and the improvement made, all should be included in the scope of protection of the technical solution of the present invention.
