Description

[Technical Field]

[0001] The present invention relates to the technical field of substrate glass manufacturing, and more particularly to a channel cooling section heat dissipation device and method of use thereof. [Background technology]

[0002] The development of the display industry has driven technological advances in the substrate glass industry, with current substrate glass technology primarily focused on high-output glass for next-generation and other OLED displays. The increased output requires further improvements in the device's structural functionality, presenting certain technical challenges in some areas. The design of channel cooling sections not only requires consideration of heat dissipation due to cross-sectional temperature gradients, but also involves many issues regarding the design of the cooling section's heat dissipation structure and length. Currently, cooling section lengths have reached the 4-5m range, and further increases in length pose challenges in various aspects, including manufacturing, installation, and safety support. Summary of the Invention [Problem to be solved by the invention]

[0003] The current heat dissipation structure can only be achieved by adjusting the thickness of the insulation bricks. In the current cooling section structure for withdrawal volumes of 20 t / d or more, the thickness of the external insulation bricks has already been reduced to 8 mm, and insulation bricks have been directly removed in several areas, limiting the room for further optimization. Therefore, a new heat dissipation structure must be considered that maximizes heat dissipation capacity within the limited space while maintaining the internal structure and ensuring structural stability and safety. The water-cooled plate method, which is sometimes used in other areas of the channel in emergencies, is classified as a localized quenching method and is not generally used widely because it requires high thermal shock resistance for the internal brick structure and has a significant impact on the internal glass temperature due to the strong localized quenching effect.

[0004] The heat dissipation structures of conventional technology have the problem that they are difficult to use widely because they require high thermal shock resistance for the internal brick structure and the local rapid cooling effect is too strong, which has an excessive impact on the internal glass temperature. [Means for solving the problem]

[0005] The present invention discloses a heat dissipation device for a channel cooling section and a method for using the same, which aims to effectively improve the heat dissipation efficiency of the cooling section and realize a wide range of flexible and controllable uses.

[0006] In order to achieve the above object, the present invention employs the following technical means. The present invention discloses a channel cooling section heat dissipation device comprising side refractory bricks, an upper refractory brick (2), a bottom support refractory brick (3), and a heat sink, the side refractory bricks including the first side refractory brick (11) and the second side refractory brick (12), the first side refractory brick (11) and the second side refractory brick (12) being arranged opposite each other, the upper refractory brick (2) being connected to the upper sides of the first side refractory brick (11) and the second side refractory brick (12), and the bottom support refractory brick (3) being connected to the lower sides of the first side refractory brick (11) and the second side refractory brick (12), forming a cavity structure for passing a platinum tube after assembly, the first side refractory brick (11), the second side refractory brick (12), and the upper refractory brick (2) having a plurality of heat dissipation gaps arranged therein, and heat sinks being installed in these heat dissipation gaps.

[0007] Furthermore, the inner surfaces of the first side refractory brick (11) and the second side refractory brick (12) are curved.

[0008] Furthermore, the side refractory bricks, the top refractory bricks (2) and the bottom support refractory bricks (3) are made of α-alumina and have an Al2O3 content of 95% or more.

[0009] Further, the heat sink includes an upper heat sink (4), a first side heat sink (51) and a second side heat sink (52), the upper heat sink (4) being arranged in the heat dissipation gap of the upper refractory brick (2), the first side heat sink (51) being arranged in the heat dissipation gap of the first side refractory brick (11), and the second side heat sink (52) being arranged in the heat dissipation gap of the second side refractory brick (12).

[0010] Furthermore, the top heat sink (4), the first side heat sink (51) and the second side heat sink (52) are made of stainless steel.

[0011] Furthermore, the first side heat sink (51) and the second side heat sink (52) are L-shaped.

[0012] Furthermore, the upper heat sink (4) has a rectangular shape.

[0013] The present invention also discloses a method for using a channel cooling section heat dissipation device, the method including the steps of: estimating the number of first side refractory bricks (11), second side refractory bricks (12), upper refractory bricks (2), and bottom support refractory bricks (3) to be installed; assembling the first side refractory bricks (11), second side refractory bricks (12), upper refractory bricks (2), and bottom support refractory bricks (3) based on the installed numbers to form a cavity structure; and attaching a heat sink to the heat dissipation gaps of the first side refractory bricks (11), second side refractory bricks (12), and upper refractory bricks (2).

[0014] Furthermore, the estimation of the installation quantities of the first side refractory bricks (11), the second side refractory bricks (12), the upper refractory bricks (2) and the bottom support refractory bricks (3) includes estimating the installation quantities based on the heat dissipation efficiency converted based on the required output.

[0015] Furthermore, when attaching the heat sinks to the heat dissipation gaps of the first side refractory brick (11), the second side refractory brick (12) and the upper refractory brick (2), the method includes distributing the heat sinks evenly in the heat dissipation gaps and increasing or decreasing the number of the heat sinks depending on the required heat conduction. [Effects of the Invention]

[0016] The channel cooling section heat dissipation device according to the present invention has the following beneficial effects. The present invention improves heat dissipation capacity by increasing the heat dissipation gap and expanding the heat dissipation area without changing the brick volume. Furthermore, the use of heat dissipation fins can further enhance the heat dissipation capacity. The number and arrangement of heat dissipation fins can be selected and combined according to process needs, meeting the adjustment requirements for different withdrawal volumes. This effectively improves the heat dissipation efficiency of the cooling section and achieves a flexible and controllable structure. The present invention improves the overall heat dissipation capacity without making major changes to the main structure of the cooling section. It also allows the distribution and stages of heat dissipation to be adjusted according to actual process needs. The designed removable side and top heat dissipation fin components allow the location and number of heat dissipation fins to be arranged and installed according to different withdrawal volume requirements and the purpose of process stage adjustment. The present invention adopts a method of joining the side refractory bricks, top refractory bricks, and bottom support refractory bricks, thereby reducing the thermal shock resistance requirements for the internal brick structure. This device employs heat dissipation fins, which can be added or removed according to operational needs, preventing excessive local quenching and minimizing the impact on the internal glass temperature. It also has a wide range of uses.

[0019] In order to facilitate those skilled in the art in understanding the technical solutions of the present invention, the following will clearly and completely describe the technical solutions of the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. It is clear that the described embodiments are only some of the embodiments of the present invention, and are not all of the embodiments. Based on the embodiments of the present invention, all other embodiments that can be obtained by those skilled in the art without creative work also fall within the scope of protection of the present invention.

[0020] It should be noted that when an element is said to be "mounted on another element," it means that it is directly mounted on the other element, or that there are other elements between them. Also, when an element is said to be "connected to another element," it means that it is directly connected to the other element, or that there are other elements between them. Terms such as "vertical," "horizontal," "left," and "right" used herein are for descriptive purposes only and do not represent the only examples.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art of the present invention. The terms used in the description of the present invention are used for the purpose of describing specific embodiments and are not intended to limit the present invention. In addition, the term "and / or" used herein includes any and all combinations of one or more of the associated items.

[0022] The first object of the present invention is to disclose a heat dissipation device for a channel cooling section (a channel cooling section heat dissipation device), which includes a side refractory brick, an upper refractory brick 2, a bottom support refractory brick 3, and a heat sink.

[0023] As shown in FIG. 1, the side refractory bricks include a first side refractory brick 11 and a second side refractory brick 12 .

[0024] A square-shaped mounting structure is formed by combining the first side refractory brick 11, the second side refractory brick 12, the top refractory brick 2, and the bottom refractory brick 3. The bottom refractory brick 3 is disposed on the lower side of the square-shaped structure, the top refractory brick 2 is disposed on the upper side of the square-shaped structure, and the first side refractory brick 11 and the second side refractory brick 12 are disposed between the top refractory brick 2 and the bottom refractory brick 3, facing each other.

[0025] The first side refractory brick 11, the second side refractory brick 12, the top refractory brick 2, and the bottom refractory brick 3 are stacked together to form a cavity inside the refractory bricks. This cavity is used to accommodate the platinum tube, preventing problems such as "red leaks" from occurring inside the refractory bricks.

[0026] As shown in FIG. 2, the inner surfaces of the first side refractory brick 11 and the second side refractory brick 12 are curved, and heat dissipation gaps are provided on the outer surfaces of the first side refractory brick 11 and the second side refractory brick 12.

[0027] As shown in Figure 3, heat dissipation gaps are provided on the outer surfaces of the top refractory bricks 2 and the bottom refractory bricks 3, and these heat dissipation gaps are distributed in multiple strips. The bottom refractory bricks 3 and the top refractory bricks 2 have similar external shapes, but no heat sink is installed in the heat dissipation gap of the bottom refractory bricks 3, as the bottom mainly functions as a support.

[0028] As shown in Fig. 4, the upper heat sink 4 is rectangular, and the first side heat sink 51 and the second side heat sink 52 are L-shaped. The first side heat sink 51 is placed in the heat dissipation gap of the first side refractory brick 11, the second side heat sink 52 is placed in the heat dissipation gap of the second side refractory brick 12, and the upper heat sink 4 is placed in the heat dissipation gap of the upper refractory brick 2. When these are attached, the structure shown in Fig. 5 is formed.

[0029] The upper heat sink 4, the first side heat sink 51 and the second side heat sink 52 are made of stainless steel.

[0030] The second object of the present invention is to disclose a method for using the heat dissipation device of the channel cooling section.

[0031] The installation quantities of the first side refractory bricks 11, the second side refractory bricks 12, the upper refractory bricks 2, and the bottom support refractory bricks 3 are calculated according to the heat dissipation efficiency converted based on the required output. Based on the calculated installation quantities, the first side refractory bricks 11, the second side refractory bricks 12, the upper refractory bricks 2, and the bottom support refractory bricks 3 are assembled to form a cavity structure. Heat sinks are attached to the heat dissipation gaps between the first side refractory bricks 11, the second side refractory bricks 12, and the upper refractory bricks 2.

[0032] The present disclosure can effectively improve the overall heat dissipation capacity of the cooling section without making any major changes to the main structure of the cooling section, and can also distribute and adjust the heat dissipation amount according to actual process requirements.

[0033] A specific example will be described below.

[0034] (Example) As shown in Figure 1, after assembly, the refractory brick structure is divided into three parts: side refractory brick, upper refractory brick 2 and bottom support refractory brick 3. After assembly, an internal cavity structure for the cooling platinum flat tube is formed to accommodate the platinum tube.

[0035] The side firebricks, upper firebricks 2 and bottom support firebricks 3 are assembled using the overlapping method, and the side firebricks, upper firebricks 2 and bottom support firebricks 3 are all made of α-alumina bricks, with an Al2O3 content of 95% or more.

[0036] The side refractory bricks, top refractory bricks 2, and bottom support refractory bricks 3 each have a heat dissipation structure, which uses a multi-fin distributed structure. Each heat sink is 10mm thick, the heat dissipation gap is 15mm, and the fin depth is generally 25mm. The number of fins is related to the length of the refractory brick, with different numbers of heat sinks being arranged for different lengths. Based on the current structural dimensions, the heat dissipation area has been increased by approximately 2 to 3 times by using only the heat dissipation method of the heat sink structure.

[0037] As shown in Figure 2, the inner curve of the side refractory brick is designed to match the side structure of the cooling flat tube, ensuring a certain amount of buffer filling space. The diameter is controlled to 220mm to 240mm, the outer shape is a rectangular parallelepiped, the cross-sectional width is 100mm to 150mm, the height is 300mm to 330mm, and the length is consistent with the length of each module of the internal heater, ranging from 300mm to 450mm.

[0038] As shown in Figure 3, the upper refractory bricks have either a flat internal structure or a curved structure to accommodate the arched upper structure of the cooling flat tube. The distance between the internal surface and the platinum tube is kept within a fixed range of 15 to 20 mm, ensuring sufficient space for the filling material. The filling space used for filling the material has a rectangular external shape, with a cross-sectional width of 400 to 600 mm, a thickness of 50 mm, and a length of 300 to 450 mm, which corresponds to the length of each module of the internal heater.

[0039] As shown in Figure 4, the heat sinks are mainly divided into two types: top heat sink 4 and side heat sink, both of which are 8 mm thick. The top heat sink 4 has a rectangular sheet-like structure, and its width is approximately 10 mm smaller than both ends of the top refractory brick 2, making it easy to install and remove. Its insertion depth is 25 mm, which matches the depth of the heat dissipation gap on the refractory brick. The side heat sink is an upside-down "L" shape, and its width and insertion depth are the same as those of the top heat sink 4.

[0040] The suitable method for the adjustable multi-piece heat dissipation structure is to simply install and remove it mechanically. The matching gap between the mounting groove and the mounting hole is 2 mm. The number of pieces to be installed is calculated based on the required heat dissipation efficiency. The corresponding temperature in this area is approximately 400°C, the corresponding heat sink thermal conductivity is 20 W / (m·K), and the thermal conductivity of the firebrick is 2.5 W / (m·K). Based on the calculation, the requirement can be met by evenly distributing 30% of the heat sinks for a standard drawing volume. For every 50 kg / h increase in drawing volume, the number of heat sinks should be increased by 10%, up to a maximum of 100% load. If the drawing volume decreases during the process, the number of heat sinks can be reduced accordingly.

[0041] Those skilled in the art will recognize from reading the above description that many other embodiments and applications beyond those described above are possible. Accordingly, the scope of the present invention should not be determined by the above description, but should instead be determined by the appended claims, along with the full scope of equivalents to which such claims are entitled. For purposes of comprehensiveness, all publications and references (including patent applications and publications) are incorporated herein by reference. The omission of any aspect of the subject matter disclosed herein from the following claims is not intended as a disclaimer of that subject matter, nor should it be construed as an indication that the applicant does not regard that subject matter as part of the disclosed invention.

[0042] The above are only preferred embodiments of the present invention, and are not intended to limit the technical solutions of the present invention. Those skilled in the art may make simple modifications and substitutions to the technical solutions of the present invention without departing from the spirit and principle of the present invention, and these modifications and substitutions will fall within the scope of protection covered by the claims of the present invention.
