Description

Technical Field

[0001] This application relates to the field of lamps, and more specifically, to a light box. Background Art

[0002] Light boxes (such as LED light boxes, infrared light boxes) are commonly used devices in the production process of photovoltaic cells. Generally, they include a box body, a heating lamp module installed on the box body, and a heat dissipation fan and a heat sink assembly installed inside the box body. Among them, the heat sink assembly is located between the heat dissipation fan and the heating lamp module, and the heat sink assembly is connected to the heating lamp module. The heat sink assembly is used to dissipate heat from the heating lamp module, and the heat dissipation fan blows air towards the middle area of the heat sink assembly to implement air-cooled cooling of the heat sink assembly.

[0003] The problem with existing light boxes is that when the heat dissipation fan blows air towards the middle area of the heat sink assembly, eddy currents or turbulences are likely to occur in the spaces on both sides of the heat dissipation fan, resulting in the cooling air flow blown by the heat dissipation fan being difficult to fully enter the heat sink assembly, ultimately affecting the heat dissipation performance of the light box. Utility Model Content

[0004] In order to solve the above technical problems, this application provides a light box, which adopts the following technical solutions:

[0005] A light box includes a box body, a heating lamp module, a heat dissipation fan, a heat sink assembly, a first wind baffle, and a second wind baffle, where:

[0006] The heating lamp module is arranged at the first side wall of the box body;

[0007] A fan installation opening is provided on the second side wall of the box body, and the heat dissipation fan is arranged at the fan installation opening. The second side wall of the box body is arranged opposite to the first side wall of the box body;

[0008] The heat sink assembly is located between the heat dissipation fan and the heating lamp module. The first surface of the heat sink assembly is connected to the heating lamp module. The heat dissipation fan is configured to blow air towards the middle area of the second surface of the heat sink assembly. The second surface of the heat sink assembly is arranged opposite to the first surface of the heat sink assembly;

[0009] A ventilation opening is provided on the box body. One of the ventilation opening and the fan installation opening serves as the air inlet of the light box, and the other serves as the air outlet of the light box. The air outlet communicates with the heat sink assembly;

[0010] The first wind baffle is arranged between the first side area of the second surface of the heat sink assembly and the second side wall of the box body;

[0011] The second wind baffle is arranged between the second side area of the second surface of the heat sink assembly and the second side wall of the box body.

[0012] In the light box provided by this application, a first wind baffle and a second wind baffle are respectively arranged in the spaces on both sides of the cooling fan. Therefore, when the cooling fan blows air at the middle area of the second surface of the heat sink assembly, no eddy current or turbulence will be generated in the spaces on both sides of the cooling fan, so that the cooling air flow blown out by the cooling fan can fully enter the heat sink assembly, improving the heat dissipation performance of the light box.

[0013] In some embodiments, the heat sink assembly includes several layers of heat sinks, and air outlet gaps are formed between adjacent heat sinks in the heat sink assembly. The air outlet gaps communicate with the ventilation openings and the fan mounting openings.

[0014] The air outlet gaps in the heat sink assembly enable the cooling air blown out by the cooling fan to flow in the heat sink assembly and finally be blown out through the ventilation openings or the fan mounting openings, so as to quickly take away the heat on the heat sink assembly and improve the heat dissipation effect.

[0015] In some embodiments, the second wind baffle is arranged in a mirror image of the first wind baffle. The first wind baffle includes a first baffle, a connecting plate and a second baffle, wherein: the first baffle covers the first side area of the second surface of the heat sink assembly; the connecting plate is arranged on the first side edge of the first baffle, and the connecting plate is fixedly connected to the third side wall of the box body; the second baffle is arranged on the second side edge of the first baffle, the first side edge is opposite to the second side edge, and the edge of the second baffle contacts the second side wall of the box body.

[0016] The first baffle, the connecting plate and the second baffle of the first wind baffle achieve the enclosure of the first side space of the cooling fan, so that the cooling air blown out by the cooling fan cannot enter the first side space of the cooling fan, further ensuring that no eddy current or turbulence will be generated in the first side space. Similarly, the first baffle, the connecting plate and the second baffle of the second wind baffle achieve the enclosure of the second side space of the cooling fan, so that the cooling air blown out by the cooling fan cannot enter the second side space of the cooling fan, further ensuring that no eddy current or turbulence will be generated in the second side space.

[0017] In some embodiments, screw holes are provided on both the connecting plate and the corresponding third side wall, and the connecting plate is screwed to the third side wall through screws passing through the screw holes.

[0018] Ensure that the first wind baffle and the second wind baffle are firmly connected to the box body, and facilitate the disassembly and assembly of the first wind baffle and the second wind baffle.

[0019] In some embodiments, the edge of the second baffle is bent towards one side to form a fitting plate, and the plate surface of the fitting plate fits with the second side wall of the box body.

[0020] The second baffle is closely attached to the second side wall of the box body through the attaching plate, preventing gaps from being generated at the contact between the second baffle and the second side wall, and preventing the cooling air from leaking into the enclosed space formed by the first baffle, the connecting plate and the second baffle through the gaps.

[0021] In some embodiments, the third side and the fourth side of the first baffle are respectively attached to two opposite fourth side walls of the box body.

[0022] The third side and the fourth side of the first baffle are respectively attached to two opposite fourth side walls of the box body, preventing the cooling air from leaking into the enclosed space formed by the first baffle, the connecting plate and the second baffle from the third side and the fourth side of the first baffle.

[0023] In some embodiments, the heat sink assembly has a U-shaped structure, and the U-shaped opening of the heat sink assembly faces the cooling fan; the middle region of the second surface of the heat sink assembly is the region where the U-shaped opening is located; the first side region of the second surface of the heat sink assembly is the region of the second surface of the heat sink assembly on the first side of the U-shaped opening; the second side region of the second surface of the heat sink assembly is the region of the second surface of the heat sink assembly on the second side of the U-shaped opening.

[0024] Setting the heat sink assembly to a U-shaped structure and arranging the cooling fan at the U-shaped opening of the heat sink assembly and blowing air towards the U-shaped opening of the heat sink assembly can enable the cooling air to enter the heat sink assembly more fully, further improving the heat dissipation effect.

[0025] In some embodiments, a terminal installation hole is further formed in the second side wall of the box body, and the terminal installation hole is directly opposite to the first baffle of the first wind shield or the first baffle of the second wind shield; a wire passing hole is provided on the first baffle of the first wind shield or the first baffle of the second wind shield, or a wire passing channel is provided between the first baffle of the first wind shield or the first baffle of the second wind shield and the inner wall of the box body.

[0026] The shielding of the terminal installation hole is realized, preventing the cooling air blown out by the cooling fan from leaking out through the terminal installation hole, reducing the loss of the cooling air, and thus further improving the heat dissipation effect.

[0027] In some embodiments, the heating lamp module includes a mounting plate and a plurality of LED lamp beads, the mounting plate is mounted on the first side wall of the box body, and the plurality of LED lamp beads are arranged on the outer surface of the mounting plate.

[0045] In order to make the above objects, features and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0046] As Figures 1 to 3 shown, the light box in the embodiment of the present application includes a box body 1, a heating lamp module 2, a heat dissipation fan 3, a heat sink assembly 8, a first wind shield 4 and a second wind shield 9, wherein:

[0047] The heating lamp module 2 is arranged at the first side wall 11 of the box body 1,

[0048] A fan mounting opening 5 is provided on the second side wall 12 of the box body 1. The cooling fan 3 is arranged at the fan mounting opening 5. The second side wall 12 of the box body 1 is arranged opposite to the first side wall 11 of the box body 1. For example, the first side wall 11 is the lower wall of the box body 1, and the second side wall 12 is the upper wall of the box body 1.

[0049] The heat sink assembly 8 is located between the cooling fan 3 and the heating lamp module 2. The first surface of the heat sink assembly 8 is connected to the heating lamp module 2. The cooling fan 3 is configured to blow air on the middle area of the second surface of the heat sink assembly 8. The second surface of the heat sink assembly 8 is arranged opposite to the first surface of the heat sink assembly 8. For example, the first surface is the lower surface of the heat sink assembly 8, and the second surface is the upper surface of the heat sink assembly 8.

[0050] A ventilation opening 7 is provided on the box body 1. One of the ventilation opening 7 and the fan mounting opening 5 serves as the air inlet of the light box, and the other serves as the air outlet of the light box. The air outlet communicates with the heat sink assembly 8.

[0051] The first wind shield 4 is arranged between the first side area (such as the right side area) of the second surface of the heat sink assembly 8 and the second side wall 12 of the box body 1.

[0052] The second wind shield 9 is arranged between the second side area (such as the left side area) of the second surface of the heat sink assembly 8 and the second side wall 12 of the box body 1.

[0053] During the operation of the light box, the heat sink assembly 8 realizes the heat dissipation of the heating lamp module 2. At the same time, the cooling fan 3 blows air on the middle area of the second surface of the heat sink assembly 8 to implement air cooling of the heat sink assembly 8. Since the first wind shield 4 and the second wind shield 9 are respectively arranged in the spaces on both sides of the cooling fan 3, when the cooling fan 3 blows air on the middle area of the second surface of the heat sink assembly 8, no eddy current or turbulence will be generated in the spaces on both sides of the cooling fan 3, so that the cooling air flow blown out by the cooling fan 3 can fully enter the heat sink assembly 8, finally improving the heat dissipation performance of the light box.

[0054] Optionally, the heat sink assembly 8 includes several layers of heat sinks. An air outlet gap is formed between adjacent heat sinks within the heat sink assembly 8, and the air outlet gap communicates with the ventilation opening 7 and the fan mounting opening 5. Specifically, the plate surfaces of the heat sinks are perpendicular to the first side wall 11 and the second side wall 12 of the box body 1 respectively. To ensure the heat dissipation effect, ventilation openings 7 are provided on two opposite third side walls 13 in the box body 1. The two third side walls 13 are vertically arranged between the first side wall 11 and the second side wall 12, and both ends of the air outlet gap communicate with the two ventilation openings 7 respectively. In this way, the cooling air blown out by the cooling fan 3 can flow in the internal gap of the heat sink assembly 8 and finally be blown out through the ventilation opening 7 or the fan mounting opening 5. When the cooling air flows in the heat sink assembly 8, it can quickly take away the heat on the heat sink assembly 8, thereby further improving the heat dissipation effect.

[0055] As Figure 3 shown, optionally, the second wind shield 9 is arranged in a mirror image of the first wind shield 4. As Figure 4 shown, taking the first wind shield 4 as an example, it includes a first baffle 41, a connecting plate 42 and a second baffle 43, where: the first baffle 41 covers the first side area of the second surface of the heat sink assembly 8. The connecting plate 42 is arranged on the first side edge of the first baffle 41, and the connecting plate 42 is fixedly connected to the third side wall 13 of the box body 1. The second baffle 43 is arranged on the second side edge of the first baffle 41, the first side edge and the second side edge are opposite, and the edge of the second baffle 43 contacts the second side wall 12 of the box body 1.

[0056] It can be seen that the first baffle 41, the connecting plate 42 and the second baffle 43 of the first wind shield 4 achieve the enclosure of the first side space of the cooling fan 3, so that the cooling air blown out by the cooling fan 3 cannot enter the first side space of the cooling fan 3, further ensuring that no eddy current or turbulence is generated in the first side space of the cooling fan 3. Similarly, the second wind shield 9 achieves the enclosure of the second side space of the cooling fan 3, so that the cooling air blown out by the cooling fan 3 cannot enter the second side space of the cooling fan 3, further ensuring that no eddy current or turbulence is generated in the second side space of the cooling fan 3.

[0057] As Figure 4 shown, optionally, screw holes are provided on both the connecting plate 42 and the corresponding third side wall 13 of the box body 1, and the connecting plate 42 is screwed to the third side wall 13 through screws passing through the screw holes. In this way, it can be ensured that the first wind shield 4 is firmly connected to the box body 1 and facilitates the disassembly and assembly of the first wind shield 4.

[0058] As Figure 4As shown, optionally, the edge of the second baffle 43 is bent towards one side to form a fitting plate 44, and the plate surface of the fitting plate 44 is attached to the second side wall 12 of the box body 1. The second baffle 43 is closely attached to the second side wall 12 of the box body 1 through the fitting plate 44, thereby preventing gaps from being generated at the contact between the second baffle 43 and the second side wall 12, and causing the cooling air to leak into the enclosed space surrounded by the first baffle 41, the connecting plate 42, and the second baffle 43 through the gaps.

[0059] Optionally, the third side and the fourth side of the first baffle 41 are respectively attached to two opposite fourth side walls 14 of the box body 1. In this way, it is possible to prevent the cooling air from leaking into the enclosed space surrounded by the first baffle 41, the connecting plate 42, and the second baffle 43 from the third side and the fourth side of the first baffle 41.

[0060] As Figure 3 shown, optionally, the heat sink assembly 8 has a U-shaped structure, and the U-shaped opening of the heat sink assembly 8 faces the cooling fan 3. The middle area of the second surface of the heat sink assembly 8 is the area where the U-shaped opening is located. The first side area of the second surface of the heat sink assembly 8 is the area of the second surface of the heat sink assembly 8 located on the first side of the U-shaped opening. The second side area of the second surface of the heat sink assembly 8 is the area of the second surface of the heat sink assembly 8 located on the second side of the U-shaped opening.

[0061] The heat sink assembly 8 is set to have a U-shaped structure, and the cooling fan 3 is arranged at the U-shaped opening of the heat sink assembly and blows air towards the U-shaped opening of the heat sink assembly 8, so that the cooling air can enter the heat sink assembly 8 more fully, thereby further improving the heat dissipation effect.

[0062] Optionally, the cooling fan 3 can be designed as 1, 2 or more according to the heat dissipation requirements.

[0063] As Figure 3 shown, optionally, a terminal installation hole 6 is further provided on the second side wall 12 of the box body 1, and the terminal installation hole 6 is directly opposite to the first baffle 41 of the first wind shield 4. A chamfer 411 is formed at the transition between the first side and the third side of the first baffle 41 of the first wind shield 4, and a wiring channel is formed between the chamfer 411 and the inner wall of the box body 1. Of course, a wiring hole penetrating the first baffle 41 can also be directly provided on the first baffle 41 of the first wind shield 4.

[0064] The cable passing through the terminal installation hole 6 into the box body 1 can be connected to the heating lamp module 2 through the wiring channel or the wiring hole to supply power to the heating lamp module 2 or implement signal interaction with the heating lamp module 2.

[0065] It can be seen that the first wind shield 4 shields the wiring terminal mounting holes 6, preventing the cooling air blown by the cooling fan 3 from leaking out through the wiring terminal mounting holes 6, thereby reducing the loss of cooling air and further improving the heat dissipation effect.

[0066] Of course, the wiring terminal mounting holes 6 can also be aligned with the first baffle of the second wind shield 9, and the second wind shield 9 shields the wiring terminal mounting holes 6.

[0067] As Figure 2 shown, optionally, the heating lamp module 2 includes a mounting plate 21 and a plurality of LED lamp beads 22. The mounting plate 21 is mounted on the first side wall 11 of the box body 1, and the plurality of LED lamp beads 22 are arranged on the outer surface of the mounting plate 21. The plurality of LED lamp beads 22 can irradiate the target object, so that the light box of the embodiment of the present application has functions such as illumination or heating.

[0068] Optionally, the heating lamp module 2 includes a mounting bracket and a plurality of infrared lamp tubes. The mounting bracket is mounted on the first side wall 11 of the box body 1, and the plurality of infrared lamp tubes are arranged side by side on the mounting bracket. The plurality of infrared lamp tubes can heat the target object, so that the light box of the embodiment of the present application has a heating function.

[0069] The above has described the present application in sufficient detail with a certain degree of particularity. Those of ordinary skill in the art should understand that the description in the embodiments is only exemplary, and all changes made without departing from the true spirit and scope of the present application should fall within the protection scope of the present application.
