Description

Technical Field

[0001] This utility model relates to the technical field of UV-LED curing system control cabinets, specifically to a UV-LED curing system control cabinet with a water-cooling device. Background Technology

[0002] Current UV curing system control cabinets house LED drivers. Since these drivers generate heat when operating, and UV-LED lighting systems for curing printing inks often require dozens of LED drivers, effective heat dissipation within the control cabinet is essential. Conventional control cabinets use fans installed through openings in the cabinet for air convection cooling. However, this method is highly susceptible to ambient temperature fluctuations; higher temperatures reduce cooling efficiency. Furthermore, the lack of a sealed enclosure allows dust to easily enter, making cleaning difficult and potentially damaging electrical components and wiring over time, thus shortening the overall lifespan of the control cabinet.

[0003] Therefore, this application is submitted. Utility Model Content

[0006] A control cabinet for a UV-LED light curing system with a water-cooling device is characterized in that it includes a surface cooler located inside the cabinet body and a chiller connected to the inlet and outlet water pipes of the surface cooler, respectively, wherein the chiller is located outside the cabinet body.

[0007] Furthermore, the back of the main body of the electrical cabinet is provided with an inlet pipe hole and an outlet pipe hole, and water pipes passing through the chiller are respectively installed in the inlet pipe hole and the outlet pipe hole, and the water pipes are respectively connected to the inlet pipe joint and the outlet pipe joint.

[0008] Furthermore, the internal piping of the surface cooler has a serpentine structure.

[0009] Furthermore, a fan is installed on the side of the surface cooler away from the water inlet pipe joint.

[0010] Furthermore, a backplate is provided on the side of the surface cooler, and the fan is detachably connected to the backplate by screws.

[0011] Furthermore, the number of fans is several.

[0012] Furthermore, an air guide plate is provided on one side of the fan adjacent to the front of the main body of the electrical cabinet.

[0013] Furthermore, the bottom of the air guide plate is provided with a connecting plate that is detachably connected to the bottom of the main body of the electrical cabinet by screws.

[0014] Furthermore, the horizontal angle between the bottom end of the air guide plate and the connecting plate is 120°~150°.

[0015] Furthermore, the interior of the main body of the electrical cabinet is equipped with LED driver power supply and control circuit components located above the surface cooler.

[0016] The beneficial effects of this utility model are:

[0017] This utility model features a surface cooler inside the main body of the electrical cabinet, which is connected to an external chiller.

[0026] Example 1

[0027] Embodiment 1 of this utility model is a control cabinet for a UV-LED light curing system with a water cooling device, including a surface cooler 4 located inside the cabinet body 1, and a chiller connected to the inlet pipe joint 40 and the outlet pipe joint 41 of the surface cooler 4 respectively. The chiller is located outside the cabinet body 1.

[0028] Reference Figures 1 to 4 This application incorporates a surface cooler 4 inside the main body 1 of the electrical cabinet. The surface cooler 4 has an inlet pipe connector 40 and an outlet pipe connector 41, which connect to the water pipes of an external chiller. The chiller's water pipes penetrate the back of the main body 1. Coolant from the chiller circulates through the water pipes and inlet connector into the internal piping of the surface cooler 4, then flows out through the outlet connector and water pipes. When the main body 1 operates, the hot air generated passes through the fins of the surface cooler 4, resulting in heat exchange at the fins and removing heat from the interior of the main body 1. This water-cooling method significantly improves heat dissipation compared to simply using a fan 5. The heat dissipation capacity is adjusted by changing the coolant temperature, and ambient temperature has little impact on its effectiveness. Furthermore, the main body 1 is a closed cabinet structure, preventing dust from entering the cabinet, keeping the interior clean, and protecting the control circuit components 2 and wiring.

[0029] In some preferred embodiments, an inlet hole 10 and an outlet hole 11 are provided on the back of the main body 1 of the electrical cabinet. Water pipes passing through the chiller are respectively installed in the inlet hole 10 and the outlet hole 11, and these water pipes are connected to the inlet pipe connector 40 and the outlet pipe connector 41, respectively. The purpose of providing the inlet hole 10 and the outlet hole 11 is to improve the installation conditions for the water pipes in the chiller within the main body 1 of the electrical cabinet, and to connect the water pipes in the chiller with the inlet and outlet connectors of the surface cooler 4, making the chiller and the surface cooler 4 form a loop, ensuring the circulation of coolant within them. The chiller and its water pipes are existing technology. The specific specifications of the inlet connector, outlet connector, inlet hole 10, and outlet hole 11 can be set according to actual needs and are not listed here. Sealing rings can also be installed at the inlet hole 10 and the outlet hole 11 to prevent external dust from entering the interior of the main body 1 through the gap between the water pipes and the chiller during heat dissipation, keeping the interior clean.

[0030] Furthermore, to enhance the heat dissipation effect of the coolant inside the surface cooler 4, the internal piping of the surface cooler 4 has a serpentine structure. The size and specifications of the serpentine structure can be set according to the actual situation, and will not be elaborated here.

[0031] To enhance the flow of hot air within the surface cooler 4, a fan 5 is installed on the side of the surface cooler 4 away from the inlet pipe joint 40. A back plate 42 is provided on the side of the surface cooler 4, and the fan 5 is detachably connected to the back plate 42 via screws. The fan 5 is mainly installed in the back plate 42 on the side of the surface cooler 4 and is detachably connected via screws, allowing for easy inspection and replacement during maintenance. Since screws are a conventional fixing method, they will not be described in detail here.

[0032] In some preferred embodiments, the number of fans 5 is several. A guide vane 6 is provided on the side of each fan 5 adjacent to the front of the main body 1. The fans 5 and the guide vane 6 combine to form a circulating air duct inside the main body 1, allowing air to circulate within the main body 1 during operation. This guide vane 6 directs hot air into the interior of the surface cooler 4 for heat exchange, improving heat dissipation.

[0033] Furthermore, a connecting plate 60 is provided at the bottom of the air guide plate 6, which is detachably connected to the bottom of the electrical cabinet body 1 by screws. The air guide plate 6 is detachably connected to the bottom of the electrical cabinet body 1, which facilitates the assembly and disassembly of the air guide plate 6.

[0034] In addition, by setting the horizontal angle between the air guide plate 6 and the connecting plate 60, the bottom end of the air guide plate 6 and the horizontal angle between the connecting plate 60 are 120°~150°. Within this range, the air inside the main body of the electrical cabinet 1 can be effectively guided when the fan 5 is working, thereby improving the heat dissipation effect of hot air.

[0035] In some preferred embodiments, the interior of the main body 1 of the electrical cabinet houses an LED driver power supply 3 and control circuit components 2 located above the surface cooler 4. The LED driver power supply 3 and control circuit components 2 are existing technologies, and their specifications and quantity can be set according to actual conditions.

[0036] The working principle of this utility model is as follows: A chiller is installed externally and connected to the inlet pipe joint 40 and outlet pipe joint 41 of the surface cooler 4 via water pipes. The coolant is transported to the internal pipeline of the surface cooler 4, circulates once, and then returns to the chiller. At this time, the hot air generated inside the main body 1 of the electrical cabinet is formed into a circulating air duct inside the main body 1 by the action of the fan 5 and the air guide plate 6, thereby guiding the hot air into the surface cooler 4. When it comes into contact with the fins, heat exchange occurs, carrying away the heat inside the main body 1 of the electrical cabinet. The heat dissipation capacity is adjusted by changing the temperature of the coolant, and the ambient temperature has little impact on its heat dissipation effect. Moreover, the enclosed structure of the main body 1 of the electrical cabinet can prevent dust from entering the cabinet, keep the inside clean, protect the control circuit components 2 and wiring, and extend the service life of the main body 1 of the electrical cabinet.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present utility model and within the spirit and principles of the present utility model shall still fall within the protection scope of the present utility model.
