Description

Technical Field

[0001] The utility model relates to the technical field of light box cooling devices, in particular to a light box cooling device and a UV light box. Background Art

[0002] Ultraviolet curing utilizes the photosensitivity of photoinitiators to form excited ecological molecules under ultraviolet light, decompose them into free radicals or ions, and cause unsaturated organic matter to undergo chemical reactions such as polymerization, contact, and cross-linking to achieve the purpose of curing. In order to extend the life of the lamp in the light box and reduce production costs, a cooling device needs to be installed inside the light box to cool the lamp.

[0003] For example, the patent with publication number CN219377823U provides a light box cooling device for ultraviolet curing system, including a box, an ultraviolet lamp body is arranged inside the box, a heat conducting plate is arranged on the top of the ultraviolet lamp body, a heat sink is arranged on the top of the heat conducting plate, a cooling chamber is arranged on the top of the box, a radiator is arranged on the outside of the cooling chamber, and a water pump is arranged on the top of the radiator. In the light box cooling device for ultraviolet curing system, heat is generated during the operation of the ultraviolet lamp body. When the heat conducting plate introduces the heat into the cooling chamber through the heat sink, the radiator is used to cool it. Since the water inlet end of the water pump is connected to the radiator through a water pipe, when the water pump is started, the cooling medium in the radiator, the water pump and the water pipe is immediately circulated, and the flowing cooling medium has excellent thermal conductivity. The cooling medium in the water pipe is cooled by the fan in the radiator, and the cooling medium in the water pipe is recycled after being cooled, so it is convenient for practical use. In the above scheme, the heat on the ultraviolet lamp body is transferred by a heat conducting plate, so that the heat on the ultraviolet lamp body cannot be quickly and directly diffused into the air for cooling.

[0004] For example, CN216591364U proposes a cooling device for a darkroom light box, which uses an exhaust fan to draw indoor cold air to the light box to reduce the overall temperature of the light box. However, in the actual process of this patent, when the cooling device is operated in an environment with relatively high ambient temperature, such as in summer, the indoor temperature is high. The exhaust fan is used to directly blow the indoor air into the light box, which cannot effectively cool the lamp tube in the light box, and the cooling effect is not good, thereby failing to effectively extend the life of the lamp tube in the light box.

The heat dissipation speed of the UV lamp is improved. At the same time, the air in the body is in a flowing state; so that the UV lamp is constantly cooled in the studio, thereby extending the service life of the UV lamp; compared with only using an exhaust fan to directly enter and exit the indoor air in the light box, the present application can effectively avoid the influence of external environmental changes on the operating state of the UV lamp.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] Example 1, please refer to Figure 1-2 As shown, the utility model relates to a light box cooling device, including a body 01 for installing a UV lamp. An air inlet pipe and an air exhaust pipe 07 are arranged on the top of the body 01, and a circulating cooling component is arranged between the air inlet pipe and the air exhaust pipe 07. A cover plate 02 is arranged at the bottom of the body 01. An installation chamber 11 is arranged in the body 01. A cover plate 02 is arranged at the opening of the installation chamber 11, one side of the cover plate 02 is connected to the body 01 through a hinge 03, so that the cover plate 02 can rotate around the hinge 03, and the other side of the cover plate 02 is connected to the body 01 through a lock 04. The cover plate 02 is buckled with the body 01 through the lock 04. A light-transmitting plate 17 is installed on the cover plate 02, and the light-transmitting plate 17 is made of quartz glass, because the transmittance of quartz glass to ultraviolet rays is usually between 80% and 90%. The ultraviolet rays generated by the UV lamp installed in the body 01 are irradiated on the workpiece through the light-transmitting plate 17.

[0025] A sealing strip is provided on the cover plate 02, and a sealing groove adapted to the sealing strip is provided on the body 01. When the cover plate 02 is in a buckled state with the body 01, the external air and dust in the air enter the body 01 through the cooperation of the sealing strip and the sealing groove.

[0026] The cover plate 02 is provided with a receiving chamber, and a square hole 15 is provided on the bottom surface of the receiving chamber. The light-transmitting plate 17 is fixed on the bottom surface of the receiving chamber by a fixing member 16 to cover the square hole 15. The area of ​​the light-transmitting plate 17 is larger than the area of ​​the square hole 15. The receiving chamber design prevents the lampshade 08 and the UV lamp in the body 01 from interfering when the cover plate 02 is buckled with the body 01. At the same time, the light-transmitting plate 17 is installed in the receiving chamber. It prevents the light-transmitting plate 17 from being scratched by external objects during transportation or placement, and plays a protective role in preventing the light-transmitting plate 17 from being scratched by external objects during transportation or placement.

[0027] The fixing member 16 includes an integrally formed connecting section and a clamping section, the connecting section is provided with a mounting hole, and a clamping groove 18 adapted to the light-transmitting plate 17 is provided between the connecting section and the clamping section. During installation, the fastener passes through the mounting hole and is threadedly connected to the bottom surface of the accommodating chamber; thereby fixing the light-transmitting plate 17 in the clamping groove 18.

[0028] A hollow lampshade 08 is fixedly installed in the body 01, and the edge of the lampshade 08 is fixedly connected to the body 01 by fasteners. The opening of the lampshade 08 is in the same direction as and coincides with the opening of the installation chamber 11 in the body 01. Two fixing plates are fixedly installed on the top of the lampshade 08 by welding or fasteners, and the side surfaces of the lampshade 08 that are perpendicular to the fixing plates abut against the body. The fixing plates are respectively a left fixing plate 09 and a right fixing plate 10. A left air inlet chamber 12 is formed between the left outer surface of the left fixing plate 09 and the lampshade 08 and the left side wall of the installation chamber 11, a right air inlet chamber 13 is formed between the right outer surface of the right fixing plate 10 and the lampshade 08 and the right side wall of the installation chamber 11, and an air outlet chamber 14 is formed between the top surface of the lampshade 08, the left fixing plate 09, the right fixing plate 10 and the top wall of the installation chamber 11, so that the air outlet chamber 14 is located between the lampshade 08 and the top of the installation chamber 11 and directly above the lampshade 08. The two air inlet chambers formed by the left air inlet chamber 12 and the right air inlet chamber 13 are located on both sides of the lampshade 08. Through holes penetrating the air inlet chamber and the air outlet chamber 14 are provided on the left fixing plate 09 and the right fixing plate 10. Since the waveguide cover on the UV lamp is installed in the lampshade 08, the lamp tube is installed in the waveguide cover, the lamp holder of the UV lamp is fixedly installed on both sides of the lampshade 08 and is located in the air inlet chamber, and the starter, photoresistor, magnetron, filament transformer, RF microwave shielding net and other structures on the UV lamp are installed on the top surface of the lampshade 08 so that they are located in the air outlet chamber 14. When the UV lamp is working, the heat generated by the starter, photoresistor, magnetron, filament transformer, RF microwave shielding net and other structures diffuses into the air in the air outlet chamber 14, and the air in the air outlet chamber 14 is discharged from the exhaust pipe 07, and then the pure cooling air obtained through cooling and air treatment returns to the air inlet chamber through the air inlet pipe. The air inlet chamber and the air outlet chamber 14 are connected by a through-hole pipe. Thus, the air in the body 01 circulates. At the same time, only the lamp tube and waveguide cover of the UV lamp are fixed in the lampshade 08, and the other structures of the UV lamp are installed in the air inlet chamber or the air outlet chamber 14, so that the UV lamp is cooled at the moment of the studio, thereby extending the service life of the UV lamp. At the same time, reduce the impact of external environmental changes on the operating status of the UV lamp.

[0029] Two air inlet pipes are arranged on the top of the body 01, and the two air inlet pipes are respectively the left air inlet pipe 05 and the right air inlet pipe 06. An exhaust pipe 07 is arranged between the left air inlet pipe 05 and the right air inlet pipe 06. The left air inlet pipe 05 is connected to the left air inlet chamber 12, and the right air inlet pipe 06 is connected to the right air inlet chamber 13. The circulating cooling component includes a cooling device connected to the exhaust pipe 07, and the cooling device is composed of a turbine fan and an evaporator, which realizes the flow of air and the cooling of the air at the same time. The air outlet of the cooling device is connected to the air handler, and the air handler is provided with a primary filter, a medium filter, and a high efficiency filter. According to different application scenarios, one of the filters, a combination of any two filters, or three filters can be selected at the same time. It is not limited here. The air handler is connected to the left air inlet pipe 05 and the right air inlet pipe 06 respectively. The air in the air outlet chamber 14 enters the cooling device through the exhaust pipe 07 under the action of the cooling device to cool the air. The cooled air is processed by the air processing unit, and then enters the air inlet chamber through the left air inlet pipe 05 and the right air inlet pipe 06. Since the air inlet chamber and the air outlet chamber 14 are connected through, the air inlet chamber flows into the air outlet chamber 14 to form a circulating flow.

[0030] Example 2, please refer to Figure 3 As shown, the difference between this embodiment and the above-mentioned embodiment 1 is that the through holes on the left fixing plate 09 and the right fixing plate 10 are set on both sides of the lampshade 08, so that the air inlet chamber and the lampshade 08 are connected through. At the same time, a connecting hole connected to the air outlet chamber 14 is set on the top of the lampshade 08. When the cold air enters the air inlet chamber from the air inlet pipe, it first enters the lampshade 08, and then flows into the air chamber 14 through the connecting hole on the top of the lampshade 08 and is discharged through the exhaust pipe 07. In this way, the air in the body 01 circulates, and the air circulation method adopted enables all parts of the UV lamp to be cooled at the same time during the operation of the UV lamp. The air is processed by the air processor and then returns to the body 01 again, thereby ensuring the cleanliness of the air in the body 01 and preventing the scattering of ultraviolet rays in the body 01.

[0031] Example 3, please refer to Figure 4As shown, the difference between this embodiment and the above-mentioned embodiment 1 is that four fixing plates are fixedly installed on the top of the lampshade 08, and an air inlet chamber 19 connected to the air inlet pipe is formed between the side of the lampshade and the side wall of the installation chamber 11 in the body. An air outlet chamber 14 connected to the exhaust pipe is formed between the four fixing plates. At the same time, the through holes on the fixing plate 09 are set on both sides of the lampshade 08, so that the air inlet chamber and the inside of the lampshade 08 are connected. At the same time, a connecting hole connected to the air outlet chamber 14 is set on the top of the lampshade 08. When the cold air enters the air inlet chamber from the air inlet pipe, it first enters the lampshade 08, and then flows into the air chamber 14 through the connecting hole on the top of the lampshade 08 and is discharged through the exhaust pipe 07. Thus, the air in the body 01 circulates, and the air circulation mode adopted enables all the components of the UV lamp to be cooled at the same time during the operation of the UV lamp. The air is processed by the air processor and then returns to the body 01, thereby ensuring the cleanliness of the air in the body 01 and preventing the scattering of ultraviolet rays in the body 01.
