Description

Technical Field

[0001] This utility model relates to the field of ultraviolet curing system technology, and in particular to a lamp box cooling mechanism for ultraviolet curing systems. Background Technology

[0002] Ultraviolet curing utilizes the photosensitivity of photoinitiators. Under ultraviolet light irradiation, photoinitiators form excited ecological molecules, which decompose into free radicals or ions, causing unsaturated organic matter to undergo chemical reactions such as polymerization, grafting, and cross-linking to achieve the purpose of curing. In order to extend the life of the lamp tubes inside the light box and reduce production costs, a cooling device needs to be installed inside the light box to dissipate heat from the lamp tubes.

[0003] Currently, most lamp box cooling mechanisms on the market transfer the heat from the lamp tube to the heat sink through a heat-conducting plate. Then, the heat sink is cooled by air cooling or water cooling, and the heat sink can continuously absorb the heat from the lamp tube, thereby achieving the effect of cooling the lamp tube. For example, a lamp box cooling device for a UV curing system disclosed in Chinese Patent Publication No. CN219377823U. However, since the maximum heat dissipation capacity of the lamp box cooling mechanism is fixed, when the lamp tube in the UV curing system is upgraded, it often cannot continue to be used due to the insufficient heat dissipation capacity of the lamp box cooling mechanism.

[0026] Example 1:

[0027] Reference Figure 1-7 A cooling mechanism for a UV curing system lamp box includes an air inlet box 1. An air inlet hole 2 is provided on the upper surface of the air inlet box 1. A fan 3 is fixedly connected to the top of the inner wall of the air inlet box 1. The air inlet hole 2 is aligned with the fan 3. The fan 3 allows air from outside the air inlet box 1 to quickly enter the air inlet box 1 through the air inlet hole 2. A first hollow cylinder 4 is fixedly connected to the bottom of the air inlet box 1. A partition column 5 is fixedly connected to the upper and lower sides of the inner wall of the first hollow cylinder 4. Water-cooling structures 6 are fitted to the left and right sides of the partition column 5 and the inner wall of the first hollow cylinder 4. Multiple water-cooling structures 6 are separated by the partition column 5. A mounting plate 7 is fixedly connected to the back of the first hollow cylinder 4. A mounting hole 8 is provided inside the mounting plate 7. The front and rear sides of the mounting plate 7 and the inner wall of the mounting hole 8 are in contact with the surface of the water-cooling structure 6.

[0028] Straight air pipes 9 are fixedly connected to both the upper and lower sides of the first hollow cylinder 4. One end of the straight air pipe 9 is fixedly connected to a solenoid valve 10. The bottom of the first hollow cylinder 4 is fixedly connected to a second hollow cylinder 11. The opening and closing of the straight air pipe 9 is controlled by the solenoid valve 10. When the water-cooling structure 6 is fixed inside the first hollow cylinder 4, the air in the air intake box 1 can enter the second hollow cylinder 11 through the water-cooling structure 6 by opening the solenoid valve 10 at the corresponding position. When the water-cooling structure 6 is disassembled, the air in the air intake box 1 cannot be directly discharged from the first hollow cylinder 4 by closing the solenoid valve 10.

[0029] A hollow plate 12 is fixedly connected to the inner wall of the second hollow cylinder 11. A heat sink 13 is fixedly connected to the inner wall of the hollow plate 12. A partition plate 14 is fixedly connected to the inner wall of the hollow plate 12. A U-shaped air pipe 15 is fixedly connected to the right side of the second hollow cylinder 11. An air outlet 16 is opened on the left side of the second hollow cylinder 11. The two ends of the U-shaped air pipe 15 are respectively connected to the upper and lower sides of the partition plate 14. The air outlet 16 is located between the partition plate 14 and the hollow plate 12.

[0030] The second hollow cylinder 11 is divided into upper and lower parts by the partition plate 14. The air above and below the partition plate 14 is connected by the U-shaped air pipe 15. The air below the partition plate 14 is discharged through the air outlet 16. The air cooled by the water cooling structure 6 first enters the upper part of the partition plate 14, and then enters the lower part of the partition plate 14 through the U-shaped air pipe 15. The cooled air carries away the heat of the heat sink 13, so that the heat sink 13 can continuously absorb heat. Finally, the air is discharged through the air outlet 16 after passing through the heat sink 13.

[0031] The water-cooling structure 6 includes a fully enclosed box 61. The left and right sides of the partition column 5, the inner wall of the first hollow cylinder 4, and the front of the mounting plate 7 are all in contact with the surface of the fully enclosed box 61. Connection holes 62 are provided on the upper and lower sides of the fully enclosed box 61. The axis of the straight air pipe 9 coincides with the axis of the connection hole 62. A first nut 63 is fixedly connected to the back of the fully enclosed box 61. The surface of the first nut 63 is in contact with the inner wall of the mounting hole 8. A bolt 64 is threadedly connected to the inner wall of the first nut 63. The front of the bolt 64 is in contact with the back of the mounting plate 7. Through the cooperation of the bolt 64, the first nut 63, the mounting plate 7, and the mounting hole 8, the fully enclosed box 61 can be fixed inside the first hollow cylinder 4. Furthermore, each water-cooling structure 6 can be disassembled and assembled individually.

[0032] A radiator 65 and a water pump 66 are fixedly connected to the front of the fully enclosed box 61. The outlet end of the radiator 65 and the inlet end of the water pump 66 are both fixedly connected to a connecting pipe 67. The inlet end of the radiator 65 and the outlet end of the water pump 66 are both fixedly connected to a water cooling pipe 68. The water cooling pipe 68 passes through the fully enclosed box 61 and extends into the fully enclosed box 61. The water pump 66 causes the coolant to circulate between the radiator 65 and the water cooling pipe 68, and the radiator 65 cools the coolant. Then, the low-temperature coolant in the water cooling pipe 68 cools the air inside the fully enclosed box 61.

[0033] Example 2:

[0034] Reference Figure 1-8 A hollow heat-conducting column 17 is fixedly connected to the bottom of the heat sink 13. A solid heat-conducting column 18 is fitted into the inner wall of the hollow heat-conducting column 17. An air groove 24 is opened on the surface of the solid heat-conducting column 18. When the solid heat-conducting column 18 moves inside the hollow heat-conducting column 17, the air inside and outside the hollow heat-conducting column 17 can circulate through the air groove 24. A heat-conducting plate 19 is fixedly connected to the bottom of the solid heat-conducting column 18. When the heat-conducting plate 19 contacts the lamp tube, the heat of the lamp tube can be transferred to the heat sink 13 through the cooperation of the heat-conducting plate 19, the hollow heat-conducting column 17 and the solid heat-conducting column 18.

[0035] A U-shaped plate 20 is fixedly connected to the upper surface of the heat-conducting plate 19. A circular hole 21 is opened on the upper surface of the U-shaped plate 20. A threaded post 22 is fitted into the inner wall of the circular hole 21. A second nut 23 is threadedly connected to the surface of the threaded post 22. The upper surface and the inner wall of the U-shaped plate 20 are in contact with the surface of the second nut 23. There are two second nuts 23 on each threaded post 22. The U-shaped plate 20 is clamped by the second nuts 23 and fixed to the threaded post 22.

[0036] Meanwhile, by changing the position of the second nut 23 on the threaded post 22, the distance between the heat-conducting plate 19 and the hollow plate 12 can be changed. Furthermore, through the cooperation of the hollow heat-conducting post 17, the solid heat-conducting post 18, the heat-conducting plate 19, the U-shaped plate 20, the round hole 21, the threaded post 22, and the second nut 23, the distance between the heat-conducting plate 19 and the hollow plate 12 can be adjusted according to the position of the lamp tube in different ultraviolet curing systems, so that the lamp box cooling mechanism can be used in a variety of ultraviolet curing systems.

[0037] In this utility model, when the user uses the cooling mechanism of the lamp box, first adjust the distance between the heat-conducting plate 19 and the hollow plate 12 according to the position of the lamp tube in the ultraviolet curing system. During adjustment, first loosen the U-shaped plate 20 by rotating the second nut 23. Then, adjust the distance between the heat-conducting plate 19 and the hollow plate 12 to a suitable size, and clamp the U-shaped plate 20 by rotating the second nut 23. At this time, the distance between the heat-conducting plate 19 and the hollow plate 12 cannot be changed through the cooperation of the threaded post 22, the second nut 23 and the U-shaped plate 20.

[0038] Then, the cooling mechanism of the light box is fixed in a suitable position, and the heat conduction plate 19 is brought into contact with the lamp tube. At this time, the heat of the lamp tube is transferred to the heat sink 13 through the cooperation of the heat conduction plate 19, the hollow heat conduction column 17 and the solid heat conduction column 18. Then, the fan, radiator 65 and water pump 66 are turned on. At this time, the coolant is circulated between the radiator 65 and the water cooling pipe 68 by the water pump 66, and the coolant is cooled by the radiator 65. Then, the air in the fully enclosed box 61 is cooled by the low temperature coolant in the water cooling pipe 68.

[0039] At the same time, the low-temperature air inside the fully enclosed box 61 is blown into the second hollow cylinder 11 by the wind generated by the fan. Through the cooperation of the partition plate 14 and the U-shaped air pipe 15, the low-temperature air is blown onto the heat sink 13. At this time, the low-temperature air carries away the heat of the heat sink 13 and enables the heat sink 13 to continuously absorb the heat of the lamp tube. Finally, the air is discharged through the air outlet 16 after passing through the heat sink 13.

[0040] When it is necessary to reduce the heat dissipation capacity of the light box cooling mechanism, firstly, by rotating the bolt 64, the bolt 64 is unscrewed from the first nut 63, and the corresponding water-cooling structure 6 is removed from the first hollow cylinder 4. Then, the corresponding solenoid valve 10 is closed. At this time, the solenoid valve 10 prevents air from being discharged through the straight air pipe 9 from the parts where the water-cooling structure 6 is not installed. By reducing the number of water-cooling structures 6 in the first hollow cylinder 4, the heat dissipation capacity of the light box cooling mechanism is reduced.

[0041] When it is necessary to increase the heat dissipation capacity of the light box cooling mechanism, first insert the water-cooling structure 6 into the first hollow cylinder 4 and make the first nut 63 contact the mounting hole 8. Then, tighten the bolt 64 into the first nut 63. Through the cooperation of the first nut 63, bolt 64, mounting plate 7 and mounting hole 8, the water-cooling structure 6 is fixed in the first hollow cylinder 4. Finally, open the corresponding solenoid valve 10 to connect the air inlet box 1, the water-cooling structure 6 and the second hollow cylinder 11. By increasing the number of water-cooling structures 6 in the first hollow cylinder 4, the heat dissipation capacity of the light box cooling mechanism is increased.
