Abstract
Description
Technical Field
[0001] The utility model discloses a plane type LED exposure machine lamp tube air cooling structure, belonging to the field of plane type LED exposure machine heat dissipation equipment. Background Art
[0002] The flat LED exposure machine will output high energy and high density during operation. A large amount of heat is released during high energy and high density output, which causes the temperature of the LED exposure machine chip to rise. When the chip temperature is higher than 70 degrees Celsius, it will bring huge thermal attenuation. In order not to affect the working effect of the LED exposure machine, the LED exposure machine needs to be continuously cooled by a heat dissipation mechanism.
[0003] In current technology, an air cooling mechanism is installed inside a flat LED exposure machine, and a strong airflow passes through the inside of the chassis where the exposure machine chip is installed, so that the heat energy of the chip can be brought out with the airflow. However, a high-volume fan will cause a large pressure difference between the inside and outside of the LED exposure machine, causing the chip board to jump back and forth, thereby affecting the service life of the exposure machine. If a low-volume fan is used, the wind force in the latter part of the airflow is insufficient, resulting in uneven heat dissipation.
[0004] In summary, the utility model provides a flat LED exposure machine lamp tube air cooling structure to solve the above problems. Utility Model Content
[0005] In view of the deficiencies in the prior art, the utility model aims to provide an air-cooling structure for a flat LED exposure machine lamp tube to solve the problem of uneven heat dissipation caused by uneven wind transmission.
[0006] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a flat LED exposure machine lamp tube air cooling structure, including a fixed frame and an exposure light board, one side of the fixed frame is fixedly connected to a mounting frame, the exposure light board is fixedly connected to the front of the mounting frame, the front of the fixed frame is fixedly connected to a fixing plate, an air exhaust outlet is opened at the bottom of the mounting frame, one side of the fixed frame is connected to a first fan unit, and the side of the mounting frame away from the fixed frame is fixedly connected to a second fan unit.
[0007] Furthermore, a plurality of heat dissipation through holes are evenly provided on the front side of the installation frame and on the back side of the exposure light board, and each heat dissipation through hole is connected to the interior of the installation frame.
[0008] Furthermore, the first air unit includes a first hair dryer, which is fixedly connected to one side of a fixed frame, an air inlet of the first hair dryer is connected to a first air inlet pipe, an air outlet of the first hair dryer is connected to a first air outlet pipe, one end of the first air outlet pipe passes through one side of the fixed frame and extends to the interior of the fixed frame, a pipe surface of the first air outlet pipe away from the first hair dryer is evenly connected to three first convection pipes from top to bottom, and one end of each first convection pipe passes through the fixed frame and the mounting frame in sequence and extends to the interior of the mounting frame.
[0009] Furthermore, each first convection tube is fixedly connected to the fixing frame, and each first convection tube is in communication with the installation frame.
[0010] Furthermore, both ends of the first air outlet pipe are bent at right angles, the first convection pipe is in a flat square tube shape, and one end of the first air outlet pipe away from the first hair dryer is blocked.
[0011] Furthermore, the second air unit includes a second hair dryer, which is fixedly connected to one side of the mounting frame, the air inlet of the second hair dryer is connected to a second air inlet duct, the air outlet of the second hair dryer is connected to a second air outlet duct, and the pipe surface of the second air outlet duct is evenly connected to three second convection ducts from top to bottom, and each second convection duct passes through one side of the mounting frame and extends to the interior of the mounting frame.
[0012] Furthermore, each second convection tube is connected to the interior of the installation frame, the end of the second air outlet tube away from the second hair dryer is blocked, and the second convection tube is in a flat square tube shape.
[0013] Beneficial effects of the utility model:
[0014] By simultaneously starting the first hair dryer inside the first air unit and the second hair dryer inside the second air unit 7, and blowing cold air into the interior of the installation frame through the first convection duct and the second convection duct, since the air outlets of the first convection duct and the second convection duct are relatively installed, and since the first hair dryer and the second hair dryer are both low-volume fans, the wind pressure in the rear sections of the air outlets of the first convection duct and the second convection duct is insufficient, but since the rear sections of the airflows of the first convection duct and the second convection duct collide with each other, an air extraction effect is generated, and then air convection is generated, thereby achieving uniform delivery of cold air inside the installation frame and uniform heat dissipation of the exposure light board.
[0015] The strong convection generated by the extraction can be discharged from the extraction outlet, and the heat generated by the exposure light board during operation can be quickly taken out with the airflow. The low air volume delivery of the first blower and the second blower reduces the pressure difference between the inside and outside of the mounting frame, so that the exposure light board will not jump on the mounting frame due to wind force, effectively extending the service life of the exposure light board.
[0016] The first convection tube and the second convection tube are both in the shape of flat square tubes, and the airflow discharged from the first air outlet pipe and the second air outlet pipe can be evenly transported to the inside of the installation frame through the first convection tube and the second convection tube in the shape of flat square tubes to form uniform convection.

DETAILED DESCRIPTION
[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0026] See also Figure 1-6The utility model provides a technical solution: a flat LED exposure machine lamp tube air cooling structure, including a fixed frame 1 and an exposure lamp board 3, one side of the fixed frame 1 is fixedly connected with a mounting frame 2, the exposure lamp board 3 is fixedly connected to the front of the mounting frame 2, the front of the fixed frame 1 is fixedly connected with a fixing plate 4, an exhaust air outlet 5 is provided at the bottom of the mounting frame 2, one side of the fixed frame 1 is connected with a first fan unit 6, and a side of the mounting frame 2 away from the fixed frame 1 is fixedly connected with a second fan unit 7, the exhaust air generated by the convection blowing of the first fan unit 6 and the second fan unit 7 can be discharged through the exhaust air outlet 5, and the heat on the chip of the exposure lamp board 3 can be taken out with the airflow, so as to achieve the heat dissipation effect of the LED exposure machine, a plurality of heat dissipation through holes are evenly provided on the front of the mounting frame 2 and on the back of the exposure lamp board 3, and each heat dissipation through hole is connected with the interior of the mounting frame 2.
[0027] See also Figure 2 , Figure 3 , Figure 4 and Figure 6 The first air unit 6 includes a first blower 61, which is connected to an external power supply and is provided with a power control switch. The first blower 61 is fixedly connected to one side of the fixed frame 1, and the air inlet of the first blower 61 is connected to a first air inlet pipe 62, and the air outlet of the first blower 61 is connected to a first air outlet pipe 63. One end of the first air outlet pipe 63 passes through one side of the fixed frame 1 and extends to the interior of the fixed frame 1. The first air outlet pipe 63 is far away from the first blower 61. The tube surface is evenly connected with three first convection pipes 64 from top to bottom, and one end of each first convection pipe 64 passes through the fixed frame 1 and the installation frame 2 in turn and extends to the interior of the installation frame 2. Each first convection pipe 64 is fixedly connected to the fixed frame 1, and each first convection pipe 64 is connected to the installation frame 2. Both ends of the first air outlet pipe 63 are bent at right angles, and the first convection pipe 64 is in a flat square tube shape. The end of the first air outlet pipe 63 away from the first blower 61 is blocked.
[0028] See also Figure 2-5The second air unit 7 includes a second air blower 71, which is fixedly connected to one side of the installation frame 2. The second air blower 71 is connected to an external power supply and is provided with a power control switch. The air inlet of the second air blower 71 is connected to a second air inlet pipe 72, and the air outlet of the second air blower 71 is connected to a second air outlet pipe 73. The pipe surface of the second air outlet pipe 73 is evenly connected to three second convection pipes 74 from top to bottom. Each second convection pipe 74 runs through one side of the installation frame 2 and extends to the inside of the installation frame 2. The first air blower 61 and the second air blower 71 are both low air volume fans, and the first convection pipe 64 and the second convection pipe 73 are connected to each other. The air outlets of the convection tube 74 are installed relative to each other. When the first hair dryer 61 and the second hair dryer 71 are started at the same time, air can be discharged simultaneously through the first convection tube 64 and the second convection tube 74 and the wind force can be relatively transmitted. Since the first hair dryer 61 and the second hair dryer 71 are both low-volume fans, the wind pressure in the rear section of the air outlet of the first convection tube 64 and the second convection tube 74 is insufficient. However, since the rear sections of the airflow of the first convection tube 64 and the second convection tube 74 collide with each other, an air extraction effect is generated, and then air convection is generated, thereby realizing uniform transmission of cold air flow inside the installation frame 2 and uniform heat dissipation of the exposure light board 3.
[0029] See also Figure 2-5 Each second convection tube 74 is connected to the interior of the mounting frame 2, and the end of the second air outlet duct 73 away from the second blower 71 is blocked. The second convection tube 74 is in the shape of a flat square tube. The airflow discharged from the first air outlet duct 63 and the second air outlet duct 73 can be evenly transported to the interior of the mounting frame 2 through the flat square tube-shaped first convection tube 64 and the second convection tube 74, and a uniform convection is formed to produce a wind extraction effect, so that the airflow can be discharged through the through holes on the mounting frame 2 and the exposure lamp board 3 is evenly cooled. The low air volume delivery of the first blower 61 and the second blower 71 reduces the pressure difference between the inside and outside of the mounting frame 2, so that the exposure lamp board 3 will not jump on the mounting frame 2 due to wind force, effectively extending the service life of the exposure lamp board 3.
[0030] Specific implementation method: By simultaneously starting the first blower 61 inside the first blower unit 6 and the second blower 71 inside the second blower unit 7, the first blower 61 draws external air through the first air inlet pipe 62, and evenly delivers the airflow to the three first convection pipes 64 through the first air outlet pipe 63, and the cold air is delivered to the inside of the installation frame 2 through the three first convection pipes 64, the second blower 71 draws external air through the second air inlet pipe 72, and evenly delivers the airflow to the three second convection pipes 74 through the second air outlet pipe 73, and the cold air is delivered to the inside of the installation frame 2 through the three first convection pipes 64. The convection duct 74 evenly transports the cold air to the interior of the installation frame 2. Since the air outlets of the first convection duct 64 and the second convection duct 74 are relatively installed, and since the first blower 61 and the second blower 71 are both low-volume fans, the wind pressure in the rear section of the air outlet of the first convection duct 64 and the second convection duct 74 is insufficient. However, since the rear sections of the airflows of the first convection duct 64 and the second convection duct 74 collide with each other, an air extraction effect is generated, and then air convection is generated, thereby achieving uniform transportation of the cold air flow inside the installation frame 2 and uniform heat dissipation of the exposure light board 3.
[0031] The strong convection generated by the extraction can be discharged from the extraction outlet 5, and the heat generated by the exposure lamp board 3 during operation can be quickly taken out with the airflow. The low air volume delivery of the first blower 61 and the second blower 71 reduces the internal and external pressure difference of the mounting frame 2, so that the exposure lamp board 3 will not jump on the mounting frame 2 due to wind force, thereby effectively extending the service life of the exposure lamp board 3.
[0032] The first convection tube 64 and the second convection tube 74 are both in the shape of flat square tubes. The airflow discharged from the first air outlet duct 63 and the second air outlet duct 73 can be uniformly transported to the interior of the installation frame 2 through the first convection tube 64 and the second convection tube 74 in the shape of flat square tubes to form uniform convection.
[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
