Description

Channel cooling section heat dissipation device and use method Technical Field

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

[0002] The development of the display industry is driving technological advancements in the substrate glass industry. Current substrate glass technology primarily focuses on high-generation, high-throughput glass and other applications for OLED displays. The increase in throughput requires further improvements to the structural functionality of the equipment, posing technical challenges in some areas. The design of the channel cooling section requires consideration not only of the temperature gradient distribution of cross-sectional heat dissipation but also of the cooling section's heat dissipation structure and length. Currently, the cooling section length has reached 4 to 5 meters, and further increases in length raise concerns regarding manufacturing, processing, installation, and secure support.

[0003] The current heat dissipation solution can only be achieved by adjusting the thickness of the insulation bricks. In the current cooling section structure for outputs above 20t / d, the thickness of the external insulation bricks has been reduced to 8mm, and several areas have been directly removed, leaving limited room for further optimization. Therefore, a completely new heat dissipation structure is needed, which ensures that the internal structure remains unchanged while maximizing heat dissipation capacity within the limited space and ensuring structural stability and safety. The water-cooled plate solution occasionally used in other emergency situations in other areas of the channel is a localized rapid cooling method that requires high thermal shock resistance of the internal brick structure. The localized rapid cooling effect is too strong, significantly affecting the internal glass temperature, and is generally not suitable for large-scale use.

[0004] Summary of the Invention

[0005] Existing heat dissipation structures in the prior art require high thermal shock resistance from the internal brick structure. Furthermore, the localized quenching effect is too strong, significantly affecting the internal glass temperature, making existing heat dissipation structures unsuitable for large-scale use. The present invention provides a channel cooling section heat dissipation device and method of use that effectively improves the heat dissipation efficiency of the cooling section, achieves flexibility and controllability, and can be used over a large area.

[0039] The first object of the present invention is to provide a channel cooling section heat dissipation device, which includes side refractory bricks, top refractory bricks 2, bottom supporting refractory bricks 3 and heat dissipation fins.

[0040] As shown in FIG. 1 , the side refractory bricks include first side refractory bricks 11 and second side refractory bricks 12 .

[0041] The first side refractory bricks 11, the second side refractory bricks 12, the top refractory bricks 2, and the bottom refractory bricks 3 are assembled to form a U-shaped installation structure.

[0042] The first side refractory bricks 11, the second side refractory bricks 12, the top refractory bricks 2, and the bottom refractory bricks 3 are assembled by overlapping. After the splicing is completed, a cavity structure is formed inside to accommodate the platinum tube, which can prevent the occurrence of problems such as internal "red leakage".

[0043] As shown in FIG2 , the inner surfaces of the first side refractory bricks 11 and the second side refractory bricks 12 are arc-shaped, and heat dissipation gaps are formed on the outer surfaces of the first side refractory bricks 11 and the second side refractory bricks 12 .

[0044] As shown in Figure 3, the outer surfaces of the top refractory bricks 2 and bottom refractory bricks 3 are provided with heat dissipation gaps, which are distributed in a multi-piece pattern. The bottom refractory bricks 3 have the same outer profile as the top refractory bricks 2, but no heat sinks are installed in the heat dissipation gaps of the bottom refractory bricks 3, mainly considering the bottom for support.

[0045] As shown in Figure 4 , the top heat sink 4 is rectangular, while the first and second side heat sinks 51 and 52 are L-shaped.

[0047] The second object of the present invention is to provide a method for using the channel cooling section heat dissipation device:

[0048] The installation quantity of the first side refractory bricks 11, the second side refractory bricks 12, the top refractory bricks 2 and the bottom supporting refractory bricks 3 is calculated according to the heat dissipation efficiency converted from the required power; according to the installation quantity, the first side refractory bricks 11, the second side refractory bricks 12, the top refractory bricks 2 and the bottom supporting refractory bricks 3 are assembled to form a cavity structure; and the heat sink is installed in the heat dissipation gap on the first side refractory bricks 11, the second side refractory bricks 12 and the top refractory bricks 2.

[0049] This application can effectively improve the overall heat dissipation capacity of the cooling section while ensuring that the main structure of the cooling section does not undergo major changes, and can distribute and select the heat dissipation level according to actual process needs.

[0050] The following is described using specific embodiments:

[0051] Example

[0052] The refractory brick structure is shown in Figure 1. After assembly, it is divided into three parts: side refractory bricks, top refractory bricks 2 and bottom support refractory bricks 3. After assembly, an internal cooling platinum flat tube cavity structure is formed to accommodate the platinum tube.

[0053] The side refractory bricks, top refractory bricks 2 and bottom supporting refractory bricks 3 are spliced ​​using an overlapping scheme. The materials of the side refractory bricks, top refractory bricks 2 and bottom supporting refractory bricks 3 are all α-alumina bricks, of which the Al2O3 content must be ≥95%.

[0054] The side refractory bricks, the top refractory bricks 2 and the bottom supporting refractory bricks 3 are all arranged with heat dissipation structures, which adopt a multi-piece distribution. The thickness of a single refractory heat sink is 10mm, the heat dissipation gap is 15mm, and the depth of the heat sink is generally 25mm. The number of heat sinks is related to the length of the refractory bricks. Different numbers of heat sinks are distributed at different root lengths. According to the current structural size, the heat dissipation area of ​​the heat sink is increased by nearly 2 to 3 times by only using the refractory structure for heat dissipation.

[0055] The side refractory bricks are shown in Figure 2. The internal curved surface is designed synchronously with the side surface structure of the cooling flat tube, and a certain buffer space for fillers is reserved. The diameter is controlled between 220mm and 240mm. The outer contour is a rectangular structure with a cross-sectional width of 100mm to 150mm and a height of 300mm to 330mm. The length is consistent with the length of a single module of the internal heater, which is between 300mm and 450mm.

[0056] The top refractory bricks are shown in Figure 3. The interior is a flat structure or a curved surface structure is adopted considering the upper arch scheme of the cooling flat tube, so that the distance between the inner surface and the platinum tube body is maintained in a fixed range of 15mm to 20mm, which is used for filling space for fillers. The outer contour is a rectangular structure with a cross-sectional width of 400mm to 600mm, a thickness of 50mm, and a length consistent with the length of a single module of the internal heater, which is between 300mm and 450mm.

[0057] The heat sinks are shown in Figure 4 and are mainly divided into two categories, namely top heat sinks 4 and side heat sinks, both of which are 8 mm thick; the top heat sink 4 is in the shape of a rectangular sheet structure, and its width is about 10 mm smaller than both ends of the top refractory brick 2, which is convenient for installation and disassembly, and the insertion depth is 25 mm, which is consistent with the heat dissipation gap depth on the refractory brick; the side heat sink is in the shape of an "L" with the upper and lower inverted sides, and its width and insertion depth are the same as those of the top heat sink 4.

[0058] The multi-piece assembly adjustable heat dissipation structure is compatible with the use of simple mechanical assembly for installation and removal. The clearance with the installation slot width is 2mm, and the number of heat sinks to be installed needs to be calculated based on the heat dissipation efficiency converted from the required power. The corresponding temperature in this area is around 400°C, and the thermal conductivity of the corresponding heat sink is 20W / (m·K), while the thermal conductivity of refractory bricks is 2.5W / (m·K). According to calculations, according to the standard lead-out rate, 30% of the heat sinks are evenly distributed to meet the requirements. For every 50kg / h increase in lead-out rate, the number of heat sinks needs to be increased by 10% until it reaches 100% of the full load. During this process, the number of heat sinks can also be reduced accordingly as the lead-out rate decreases.

[0059] Many embodiments and applications beyond the examples provided will be apparent to those skilled in the art upon reading the foregoing description. Therefore, the scope of the present teachings should be determined not with reference to the foregoing description, but rather with reference to the preceding claims, along with the full scope of equivalents to which such claims are entitled.
