Description

[Technical Field]

[0001] The present invention relates to a device for adjusting the amount of working fluid injected into a heat pipe, which adjusts the amount of working fluid contained inside the heat pipe to a set storage state. [Background technology]

[0002] Generally, a heat pipe is a heat transfer device manufactured by forming a vacuum inside a metal case, injecting a working fluid, and then evacuating the inside and sealing the vacuum.

[0003] When heat is applied to one side of a heat pipe, the working fluid inside evaporates, moves to the other side where heat is not applied, condenses, and then returns. In other words, a heat pipe is a heat transfer device that rapidly transfers heat using latent heat of evaporation.

[0004] In this case, the working fluid injection into the heat pipe will be explained. After injecting the working fluid into the heat pipe, the heat pipe is heated to expel vapor containing impurities, and the heat pipe is sealed to fill the heat pipe with a predetermined amount of working fluid.

[0005] However, in the conventional heat pipe, even if the working fluid is initially injected at a set amount, after heating, some of the working fluid is discharged in a vapor state, making it difficult to determine whether the working fluid is finally filled to the set amount inside the heat pipe.

[0006] The related technology regarding the injection of working fluid into a heat pipe is disclosed in Korean Patent Publication No. 10-0604234 (July 18, 2006). Summary of the Invention [Problem to be solved by the invention]

[0007] The present invention provides a device for adjusting the amount of working fluid injected into a heat pipe, which adjusts the amount of working fluid injected so that the working fluid is filled at a set constant level even after the heat pipe is heated. [Means for solving the problem]

[0008] The present invention provides a heat pipe working fluid injection amount adjusting device, which includes: a stationary frame that supports a heat pipe containing a working fluid in an upright state so that the heat pipe can move up and down; a heating unit that heats the heat pipe; a constant pressure support unit that is connected to the lower end of the heat pipe and supports the heat pipe under a predetermined pressure condition; and a position confirmation unit that is provided on the stationary frame and makes it possible to confirm the position of the heat pipe as it moves up and down.

[0009] The stationary frame may also include a pillar portion arranged parallel to the heat pipe and having the position confirmation portion provided thereon, and a connecting portion connected to the pillar portion and having upper and lower guide grooves that guide the heat pipe to move in the vertical direction.

[0010] The heating unit is also an induction heater.

[0011] The constant pressure support unit may include a support base that is arranged to be movable in the vertical direction and supports the lower end of the heat pipe, a pneumatic device equipped with a regulator to generate air pressure at a predetermined constant pressure, and an air pressure line that connects the pneumatic device and the support base and guides the air pressure generated by the pneumatic device to be supplied to the support base.

[0012] The support may include a support body having a support groove into which the lower end of the heat pipe is inserted, and an air pressure transmission plate connected to the support body and disposed inside the high-pressure line to transmit air pressure generated from the air pressure device to the support body.

[0013] The position confirmation portion is also a scale provided at a predetermined interval in the vertical direction of the stationary frame. [Effects of the Invention]

[0014] In the heat pipe working fluid injection amount adjusting device according to the present invention, a heat pipe containing working fluid is supported by a constant pressure support unit at a predetermined pressure state and is arranged upright on a stationary frame so as to be movable up and down. When the heating unit heats the heat pipe and the weight decreases due to evaporation of the working fluid, the position checking unit checks the rising position of the heat pipe to easily adjust the amount of working fluid injected into the heat pipe to a predetermined constant state.

DETAILED DESCRIPTION OF THE INVENTION

[0016] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, the terms and words used in the specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings, but should be interpreted as meanings and concepts that correspond to the technical ideas of the present invention, based on the principle that the inventor can appropriately define the concepts of terms in order to best describe his / her invention.

[0017] 1 and 2, a heat pipe working fluid injection amount adjusting device according to an embodiment of the present invention may include a stationary frame 100, a heating unit 200, a constant pressure support unit 300, and a position confirmation unit 400.

[0018] The stationary frame 100 supports the heat pipe 10, which contains a working fluid. More specifically, the stationary frame 100 supports the heat pipe 10 in an upright position so that the heat pipe 10 can move up and down. In this case, the heat pipe 10 supported by the stationary frame 100 has an open top, from which steam is discharged when heated by the heating unit 200. Here, the stationary frame 100 may include a column portion 110 and a connecting portion 120.

[0019] The pillars 110 are installed vertically on the bottom surface of the installation location so as to be parallel to the heat pipes 10. In this case, the length of the pillars 110 may be longer than the length of the heat pipes 10. A bottom plate (not shown) may be provided at the lower end of the pillars 110 so that the pillars 110 can be stably placed on the bottom surface of the installation location.

[0020] The connecting part 120 is a part that guides the heat pipe 10 to be movable in the vertical direction. The connecting part 120 is connected to one side of the pillar part 110 in a vertical position. The connecting part 120 may have an upper and lower guide groove 121 that penetrates in the vertical direction. The upper and lower guide groove 121 connects the heat pipe 10 to the connecting part 120 in an inserted state, so that the heat pipe 10 is arranged in the connecting part 120 to be movable in the vertical direction.

[0021] The heating unit 200 is a means for heating the heat pipe 10 disposed on the stationary frame 100. That is, the heating unit 200 heats the heat pipe 10 to expel impurities in the heat pipe 10 in a vapor state. It is preferable that the heating unit 200 uses an induction heater, but it is needless to say that the heating unit 200 is not limited to this.

[0022] The constant pressure support unit 300 supports the heat pipe 10 under a predetermined pressure condition. That is, the constant pressure support unit 300 supports the lower end of the heat pipe 10, which is arranged on the stationary frame 100 so as to be movable up and down, with air pressure at a predetermined constant pressure. When the volume of the working fluid contained in the heat pipe 10 decreases as the working fluid is heated through the heating unit 200, the constant pressure support unit 300 moves the heat pipe 10 upward by an amount equal to the decreased volume. The constant pressure support unit 300 is connected to the lower end of the heat pipe 10 so as to support the lower end of the heat pipe 10. Here, the constant pressure support unit 300 may include a support stand 310, an air pressure device 320, and an air pressure line 330.

[0023] The support stand 310 supports the lower end of the heat pipe 10 in a seated state. The support stand 310 may include a support body 311 and an air pressure transmission plate 312. A support groove 311a may be formed on the upper side of the support body 311 so that the lower end of the heat pipe 10 can be inserted therein. The air pressure transmission plate 312 is a plate that transmits air pressure generated through the air pressure device 320 and the air pressure line 330 to the support body 311. The air pressure transmission plate 312 is disposed inside the air pressure line 330, and more specifically, is disposed inside one end of the air pressure line 330 so as to be slidable in the vertical direction. A sealing member 312a may be provided on the outer surface of the air pressure transmission plate 312, i.e., the surface that contacts the inner surface of the air pressure line 330, to seal the space between the inner surface of the air pressure line 330 and the support body 311.

[0024] The pneumatic device 320 generates air pressure. The pneumatic device 320 is connected to an air pressure line 330 and supplies the generated air pressure to the air pressure line 330. The pneumatic device 320 may include a regulator 320a so that the air pressure is maintained at a predetermined constant pressure when the air pressure is generated.

[0025] The air pressure line 330 is a flow path that guides the air pressure generated by the air pressure device 320 to be supplied to the support 310. One end of the air pressure line 330 is connected to the air pressure transmission plate 312 of the support 310, and the other end of the air pressure line 330 is connected to the outlet of the air pressure device 320.

[0026] The position confirmation unit 400 allows an operator to confirm the vertical position of the heat pipe 10 due to its vertical movement, and more specifically, the position of the support base 310 of the constant pressure support unit 300 due to a change in the weight of the heat pipe 10. That is, the position confirmation unit 400 allows an operator to confirm the position of the heat pipe 10, i.e., the vertical position of the support body 311 of the support base 310, which is raised by the pressure of the constant pressure support unit 300 as the working fluid in the heat pipe 10 evaporates due to the heating of the heat pipe 10 by the heating unit 200. Here, the position confirmation unit 400 may be provided on the mounting frame 100, and more specifically, on the pillars 110 of the mounting frame 100. In this case, the position confirmation unit 400 is a scale provided at regular intervals in the vertical direction on the pillars 110 of the mounting frame 100, but is not limited thereto and may of course be a height measurement sensor.

[0027] The operation of adjusting the amount of working fluid injected into a heat pipe using the device for adjusting the amount of working fluid injected into a heat pipe according to the present embodiment will be described below.

[0028] First, the heat pipe 10 containing the working fluid is placed on the support base 310 of the constant pressure support part 300 and is arranged so as to be supported by the stationary frame 100 .

[0029] The air pressure device 320 of the constant pressure support unit 300 generates air pressure so that the heat pipe 10 is placed and supported on the support base 310 under a predetermined pressure condition. In this state, the heat pipe 10 is kept fixed at a constant position in the vertical direction.

[0030] Thereafter, the heat pipe 10 is heated by the heating unit 200 so that the working fluid is accommodated in the heat pipe 10 together with the impurities therein by a set amount.

[0031] As described above, the heating unit 200 heats the heat pipe 10 , and the weight of the heat pipe 10 is reduced through evaporation of impurities and working fluid, so that the heat pipe 10 rises due to the pressure applied by the constant pressure support unit 300 .

[0032] The position of the heat pipe 10 is confirmed by the position confirmation unit 400, and when the heat pipe 10 is moved to a certain position, the heating unit 200 stops heating the heat pipe 10.

[0033] Thereafter, when the upper end of the heat pipe 10 is sealed, the working fluid in the heat pipe 10 is completely contained in a precisely controlled manner at a set injection amount.

[0034] In this way, in one embodiment of the heat pipe working fluid injection amount adjustment device, the heat pipe 10 containing the working fluid is supported at a predetermined pressure by the constant pressure support unit 300 and is arranged upright on the stationary frame 100 so that it can move up and down. When the heating unit 200 heats the heat pipe 10 and the weight decreases due to evaporation of the working fluid, the position confirmation unit 400 confirms the rising position of the heat pipe 10, making it possible to easily adjust the amount of working fluid injected into the heat pipe 10 to a set constant state.

[0035] Although the present invention has been described with reference to the embodiments shown in the drawings, these are merely illustrative, and those skilled in the art will recognize that various modifications and equivalent embodiments are possible. Therefore, the true technical scope of protection of the present invention should be determined by the technical spirit of the claims.
