DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As described above, the present invention is a storage device (10) for preventing the organic compound for OLED (hereinafter, referred to as "content") from being quickly exhausted even in a high temperature and high vacuum state, A holder 200 in which the storage container 200 is installed and in which the cooling water flows to one side; a heating unit H installed at one side of the storage container 200; And a suction device (not shown) communicating with one side of the holder 100 and forming a vacuum inside the holder 100 and the storage container 200.

That is, the storage container 200 can be placed in a high-temperature environment by the heating unit H, while being put in a high-vacuum state by a suction device, thereby accurately simulating the actual deposition state of the OLED organic compound.

The suction device may include a suction pump and a suction pipe communicating with the suction pump, for example, for sucking air into a vacuum state, which is well known in the art. It is omitted.

The holder 100 includes a holder body 110 having a hollow shape and open on a lower side, the holder body 110 being installed on a storage container 200 whose upper side is opened and communicating with the storage container 200, A suction port 120 formed at one side of the holder 110 and communicating with the suction device to discharge air inside the holder body 110 and the storage container 200; And a cooling water channel 130 through which the cooling water flows.

That is, the holder body 110 has a hollow shape with the lower side opened, and the storage container 200 has a hollow shape with the upper side opened. At this time, the holder body 110 is installed on the storage container 200 to communicate with each other.

Meanwhile, the suction port 120 may be installed on one side of the holder main body 110 to communicate with a suction device (not shown). At this time, the air remaining in the holder main body 110 and the storage container 200 may be discharged through the suction port 120 so that the inside of the holder main body 110 and the storage container 200 may be evacuated.

As described above, the high-temperature storage apparatus 10 of the present invention may include a cooling water flow path 130 formed in the holder main body 110 for cooling the high-temperature storage apparatus 10 to cool the high temperature storage apparatus 10.

At this time, the cooling water channel 130 may be formed as a passage through which the cooling water can flow on the thickness surface of the holder body 110, as shown in FIG.

Since the holder body 110 and the storage container 200 are coupled to each other as described above and maintained in a vacuum state, they must be kept airtight. The holder flange 140 and the storage container flange 200F are formed on the surfaces of the holder body 110 and the storage container 200 that are in contact with each other, And a sealing part 115 mounted between the storage container side flange 200F and the storage container side flange 200F. The holder side flange 140 and the storage container side flange 200F may protrude outward as shown in FIG. 1, and the holder side flange 140 and the storage container side flange 200F And can be mutually fixed via fasteners (not shown) in contact with each other.

As is well known, bolts or the like can be used as the fastener, which is well known in the art, and therefore, detailed description and illustration are omitted.

Meanwhile, the sealing portion 115 is mounted between the holder side flange 140 and the storage container side flange 200F to maintain airtightness as described above, and an O-ring or the like can be used.

The storage container 200 may include a hollow storage container body 210 having a circular section as shown in FIG. Also, the holder body 110 has a circular cross-section, and has a hollow shape, so that the holder body 110 can be brought into contact with the storage container 200.

However, this is only an example for explaining the storage container 200 and the holder 100 of the present invention. As long as the contents are stored and mutually coupled to maintain the vacuum as described above, the storage container 200 And the holder 100 have different shapes, it goes without saying that they belong to the category of the present invention.

In addition, in the present invention, it is described that OLED organic compounds are stored in a high-temperature and high-vacuum state without disappearing as contents. However, the OLED organic compounds are only examples of the present invention, Liquid, gaseous, solid or sol or gel state, and the like).

The storage container 200 may be made of quartz so that the chemical can be stably stored, or a transparent material can be used for easy observation from the outside.

In the case of the heating unit H, the heating unit H may be a coil-shaped heater, and may be made of tungsten. However, the heating unit H is intended to heat the storage container 200 so that the contents are placed in a high-temperature environment. As long as the heating unit H achieves this object, All fall within the scope of the present invention.

2, the heating unit H includes a lower heating unit H1 installed on the lower side of the storage container 200 and a lower heating unit H1 disposed on the upper side of the storage container 200, And an upper heating unit H2 for heating the storage container 200 of the evaporated portion. The contents S1 stored in the storage container 200 may be evaporated by the heating section H and deposited on the inside of the upper portion of the storage container 200 as shown in Figure 2 ). If the thickness of the deposited contents S2 continues to increase, the inside of the storage container 200 is eventually blocked, so that the discharge of air for vacuum maintenance may be difficult as described above.

To prevent this, an upper heater (H2) may be provided for heating a portion where the content (S2) is deposited so that the deposited content (S2) is heated and melted and returned to a portion where the original content is stored And a lower heating unit H1 for heating the lower portion of the storage container 200 to heat the contents S1 stored in the lower portion of the storage container 200. [ At this time, power is continuously applied to the lower heating unit H1 in order to keep the contents at a high temperature at all times, while the upper heating unit H2 is heated only at a predetermined interval only when the contents are volatilized, .

Also, as described above, it may include two heating units H1 and H2, but it may include a movable heating unit H3 and a transfer unit H4 as shown in FIG. That is, when one of the heating parts is raised and lowered to heat the original stored contents S1 and evaporation occurs by evaporation inside the upper part of the storage container 200 as described above, the heating part is raised to the deposited part, It is possible to heat the content S2 and then return to the original position to heat the original stored content S1. To this end, the mobile heating unit H3 and the transfer unit H4 may be included.

The transfer section H4 may be a hydraulic or pneumatic cylinder as is well known and the movable heating section H3 may be attached to the cylinder.

The storage container 200 may have a certain radius as shown in FIGS. 1 to 3, but the height of the contents S as shown in FIG. 4 is not limited to the evaporated portion (S2 of FIGS. 1 to 3) ) May be formed larger than the width of the peripheral portion. That is, as shown in the drawing, the width (diameter) of the portion 220 where the contents S is evaporated in the storage container 200 is smaller than the width (diameter) of the peripheral portion, that is, the lower portion 230 or the upper portion 210 Can be largely formed. This is because if the width of the deposited portion 220 is increased, the storage container 200 is not shut off due to a sufficiently large diameter even if the deposition thickness of the contents increases, so that high vacuum can be easily maintained.

1 to 4, a shutoff cap 300 installed at a position higher than the contents stored in the storage container 200 to block the inside of the storage container 200, And a temperature gauge 400 installed inside the cap 300 to support the shutoff cap 300.

As described above, the contents S stored in the storage container 200 may be evaporated and deposited (S2). To prevent this, the shutoff cap 300 is installed inside the storage container 200 so that the evaporated contents So that it does not rise.

On the other hand, as described above, since the contents (S2, see FIGS. 1 to 3, hereinafter the same) deposited by evaporation are melted and returned to the original position, the contents S2 pass through the shutoff cap 300 And the contents gathered in the central portion of the shutoff cap 300 should also be able to return to the original stored position.

For this, the shutoff cap 300 may use a deformation-type shutoff cap 310 as shown in FIG. The deformation-type shutoff cap 310 includes a cap body 311 having a disk shape and having a through-hole 311a through which the temperature measuring device 400 passes, and closely contacting the inner surface of the storage container 200, And a deformation part 312 protruding radially from the outer circumference of the main body 311 but formed in a plurality of circumferential directions and deforming in close contact with the inner surface of the storage container 200.

The deformed portion 312 is initially positioned on the same plane as the cap body 311 but when the cap body 311 is mounted inside the container 200, And may be deformed toward the upper side of the cap body 311 as shown in FIG. At this time, through the empty space generated between the deformation portion 312 and the interior of the storage container 200 or between the deformation portion 312 and the cap body 311 or between the deformation portions 312 adjacent to each other, The contents S2 that have been deposited by the deposition can be melted and returned to the original position. Of course, since the space inside the storage container 200 is almost blocked by the shutoff cap 310, most of the content rising due to evaporation can be blocked.

Meanwhile, as shown in FIG. 5, adjacent deformation portions 312 may be spaced apart from each other to form a space through which the deposited contents S2 can pass. The shape of the deformable part 312 may be a rectangular shape as shown in the figure, but it is only one embodiment for explaining the present invention. All of the deformed portions 312 are of a different shape, of course, all fall within the scope of the present invention.

Meanwhile, as shown in FIG. 6, the shutoff cap 300 may have a height higher than a peripheral portion thereof. This is because the contents S2 evaporated by the evaporation may melt and flow downward in the storage container 200 and some of the contents blocked by the shutoff cap 300 may be stored in the center of the shutoff cap 300 . The stored contents are formed so as to flow toward the periphery side and pass through the shutoff cap 300 as described above so as to be returned to the original position.

Meanwhile, the shutoff cap 300 may be a close-contact shutoff cap 320 as shown in FIG. The capping cap 320 includes a cap body 321 having a disk shape and having a through hole 321a through which the temperature measuring device 400 passes and closely contacting the inner surface of the storage container 200, And a plurality of flow grooves 322 formed in the outer periphery of the main body 311 in the radial direction but formed in the circumferential direction and forming a void space between the inner surface of the storage container 200 and the inner surface of the storage container 200.

That is, in the case of the close-contact type shut-off cap 320, a portion which is not in close contact with the inner side surface of the storage container 200, that is, a flow groove 322 is formed so that the above-described deposition contents S2 pass through the shut- Position.

Meanwhile, in the case of the contact-type shutoff cap 320, the height of the central portion of the cap body 321 may be higher than the peripheral portion.

As shown in the drawing, the flow grooves 322 may have a circular shape, but this is only one embodiment for explaining the present invention. As described above, the flow grooves 322 may be formed in the flow grooves 322, 322 are of different shapes, they are all within the scope of the present invention.

The shutoff cap 300 may be supported by a temperature sensor 400 as shown in FIG. 1. The temperature sensor 400 includes a storage container 200 and a holder 100 In the vertical direction. It is to be understood that the present invention is not limited to the above-described embodiment, and it is to be understood that even when the shape or installation position of the temperature measuring device 400 is changed as long as it can support the shutoff cap 300, Of course.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the same is by way of illustration and example only and is not to be construed as limiting the present invention. It is obvious that the modification or improvement is possible.

Further, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
