Description

Technical Field

[0001] The utility model relates to the technical field of LCD liquid crystal modules, in particular to an LCD liquid crystal module with uniform heat dissipation. Background Art

[0002] With the rapid development of science and technology, liquid crystal display technology (LCD) has been widely used in various electronic devices, including smart meter display screens, U-shield screens, electric vehicle screens, small appliance screens, etc. However, with the improvement of equipment performance, the heat dissipation problem of LCD modules has become increasingly prominent. Good heat dissipation performance can not only ensure the stable operation of LCD modules, but also extend their service life. Therefore, how to reduce production costs while ensuring heat dissipation has always been a technical problem in the industry.

[0003] Traditional heat dissipation design of LCD liquid crystal modules usually adopts a large-area heat sink. Although the heat dissipation effect is good, the production cost is high. In addition, due to the limited contact area between the heat sink and the LCD liquid crystal module, the heat dissipation uniformity is also affected.

[0004] In recent years, the industry has begun to explore the use of new heat dissipation structures such as heat pipes and heat dissipation fins to improve heat dissipation uniformity and efficiency. However, these new heat dissipation structures are difficult to design and manufacture, and the production cost is also increased accordingly, which limits their application in low-cost LCD liquid crystal modules.

[0005] For example, the patent specification of an existing Chinese patent (publication number: CN218917860U) discloses an LCD liquid crystal module, including a module body, a wind hood is arranged on the rear side of the module body, a positioning tube is arranged in the middle of the outer side of the wind hood, a fan is arranged in the positioning tube, and an outer wall of the wind hood is provided with an air outlet pipe connected to the inner cavity and close to the outer periphery.

[0006] However, in the implementation of relevant technologies, it was found that the LCD liquid crystal module of the above design had the following problems: although the device realizes uniform heat dissipation of the LCD liquid crystal module by installing multiple heat dissipation fins in conjunction with parts such as fans, heat conducting rods and heat conducting plates, the cost of the heat dissipation fins is relatively high. The device not only uses multiple heat dissipation fins, but also installs multiple auxiliary parts. These parts greatly increase the production cost, which is not conducive to the subsequent market competition of the device.

[0007] In view of this, an LCD liquid crystal module with uniform heat dissipation is provided to overcome the above-mentioned defects. Utility Model Content

[0008] The utility model aims to solve the shortcomings in the prior art and proposes an LCD liquid crystal module with uniform heat dissipation.

[0009] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an LCD liquid crystal module with uniform heat dissipation, comprising a module body, a heat conduction plate is fixedly installed at the rear of the module body, a plurality of guide and heat dissipation strips are fixedly installed on the rear side of the heat conduction plate, a motor is fixedly installed at the middle position of the rear side of the heat conduction plate, a plurality of turbine blades are fixedly installed on the outer wall of the motor, and an air outlet plate is fixedly installed at the rear edge position of the heat conduction plate.

[0010] As a further description of the above technical solution: a sealing plate is fixedly connected to the inner wall of the air outlet plate, a circular air inlet compatible with the motor and turbine blades is opened in the middle position of the outer wall of the sealing plate, a dustproof plate is arranged on the rear side of the circular air inlet, and a limiting block is arranged on the rear side of the dustproof plate.

[0011] As a further description of the above technical solution: the shape of the guide heat dissipation strip is arc-shaped, and the specific material of the guide heat dissipation strip is copper. By setting the guide heat dissipation strip to be arc-shaped and setting its material to copper, the guide heat dissipation strip can introduce the heat of the heat conduction plate to a greater extent.

[0012] As a further description of the above technical solution: a first limit frame is fixedly installed on the rear outer wall of the sealing plate, and second limit frames are fixedly installed on both sides of the first limit frame. The dustproof plate is located in the middle of the first limit frame and the second limit frame. By setting the first limit frame and the second limit frame, the dustproof plate is limited and will not be easily displaced.

[0013] As a further description of the above technical solution: the number of the second limiting frames is two, and a slide groove is provided in the middle position of the outer wall of the two second limiting frames, and the slide groove is adapted to the limiting block.

[0014] As a further description of the above technical solution: a mounting block is fixedly installed on the rear outer wall of the sealing plate, a slidable slide rod is installed inside the mounting block, one end of the slide rod is fixedly connected to one side of the limit block, and the other end of the slide rod is fixedly connected to a pull tab, and a resistance spring is fixedly connected between the limit block and the mounting block. By setting the slide rod and fixing the resistance spring between the limit block and the mounting block, the limit block is initially pressed against the top of the dustproof plate by the elastic force of the resistance spring, thereby limiting the dustproof plate and preventing the dustproof plate from falling off the device.

[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model designs an LCD liquid crystal module with uniform heat dissipation. By setting a motor and turbine blades and cooperating with guide heat dissipation strips, the heat absorbed by the heat conduction plate can be evenly discharged to the greatest extent. Compared with the existing device, the device has a simple structure and low cost. While ensuring the heat dissipation effect, the cost expenditure of the device is reduced.

[0017] 2. The utility model designs an LCD liquid crystal module with uniform heat dissipation. By setting a dustproof plate, dust can be prevented from entering the interior of the device to increase the service life of the device. By setting a limit block, a sliding rod and a resistance spring, the dustproof plate can be easily disassembled and the dustproof plate is easier to clean. These settings increase the practicality of the device while maintaining the function of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Embodiment 1

[0025] Reference Figure 1-4 The utility model provides an LCD liquid crystal module with uniform heat dissipation: comprising a module body 1, a heat conducting plate 4 is fixedly installed at the rear of the module body 1, a plurality of flow-guiding heat dissipation strips 16 are fixedly installed at the rear side of the heat conducting plate 4, a motor 14 is fixedly installed at the middle position of the rear side of the heat conducting plate 4, a plurality of turbine blades 15 are fixedly installed on the outer wall of the motor 14, an air outlet plate 2 is fixedly installed at the rear edge position of the heat conducting plate 4, the flow-guiding heat dissipation strip 16 is in an arc shape, and the specific material of the flow-guiding heat dissipation strip 16 is copper. By setting the flow-guiding heat dissipation strip 16 in an arc shape and setting its material to copper, the flow-guiding heat dissipation strip 16 can introduce the heat of the heat conducting plate 4 to a greater extent.

[0026] During specific implementation, the module body 1 will generate heat when in use. After the module body 1 generates heat, the heat will be conducted to the back side of the module body 1 by the heat conduction plate 4. At this time, the motor 14 is started. After the motor 14 is started, it will drive multiple turbine blades 15 to rotate. After the turbine blades 15 rotate, air will be drawn in from the circular air inlet, and then the special shape of the turbine blades 15 will send more air to the side. Before the turbine blades 15 send out the air, multiple heat guide strips 16 have already transferred the heat on the surface of the heat conduction plate 4 to the heat guide strips 16 themselves to the greatest extent. After the turbine blades 15 push the air, the flowing air will take away the heat from the surface of the heat conduction plate 4 and the surface of the heat guide strips 16, and transmit it from the air outlet plate 2 to the outside of the device. In the process, most of the heat generated by the module body 1 is taken out, ensuring the quality and uniformity of heat dissipation.

[0027] By providing a motor 14 and turbine blades 15 in combination with the guide heat dissipation strips 16, the heat absorbed by the heat conducting plate 4 can be discharged evenly to the greatest extent. Compared with the existing devices, this device has a simple structure and low cost, which reduces the cost of the device while ensuring the heat dissipation effect.

[0028] Embodiment 2

[0029] Reference Figure 1-4 The utility model provides an LCD liquid crystal module with uniform heat dissipation: a sealing plate 3 is fixedly connected to the inner wall of the air outlet plate 2, a circular air inlet matched with the motor 14 and the turbine blade 15 is opened in the middle position of the outer wall of the sealing plate 3, a dustproof plate 8 is arranged on the rear side of the circular air inlet, a limiting block 9 is arranged on the rear side of the dustproof plate 8, a first limiting frame 5 is fixedly installed on the outer wall of the rear side of the sealing plate 3, and second limiting frames 6 are fixedly installed on both sides of the first limiting frame 5, and the dustproof plate 8 is located in the middle of the first limiting frame 5 and the second limiting frame 6. By setting the first limiting frame 5 and the second limiting frame 6, the dustproof plate 8 is limited and will not be easily displaced, and the number of the second limiting frames 6 is two , a slide groove 12 is provided in the middle position of the outer wall of the two second limit frames 6, and the slide groove 12 is adapted to the limit block 9. A mounting block 7 is fixedly installed on the outer wall of the rear side of the sealing plate 3, and a slidable slide rod 10 is installed inside the mounting block 7. One end of the slide rod 10 is fixedly connected to one side of the limit block 9, and the other end of the slide rod 10 is fixedly connected to a pull tab 11. A resistance spring 13 is fixedly connected between the limit block 9 and the mounting block 7. By setting the slide rod 10 and fixing the resistance spring 13 between the limit block 9 and the mounting block 7, the limit block 9 is initially resisted by the elastic force of the resistance spring 13 above the dustproof plate 8, thereby limiting the dustproof plate 8 and preventing the dustproof plate 8 from falling out of the device.

[0030] In specific implementation, on the basis of the above-mentioned embodiment 1, dust may be driven into the device during the use of the motor 14 and the turbine blades 15, and the dust can be filtered by setting the dustproof plate 8 to prevent dust from entering the interior of the device. The dustproof plate 8 needs to be cleaned after being used for a long time. During cleaning, the pull tab 11 can be pulled, and the pull tab 11 will drive the slide bar 10 to move after being pulled, and the other end of the slide bar 10 is fixedly connected to the limit block 9, so the limit block 9 will also be driven to move. After both limit blocks 9 are driven to move, the one-way limit on the dustproof plate 8 will disappear, and the dustproof plate 8 can be easily taken out at this time, and it can be cleaned or replaced.

[0031] By setting up the dustproof plate 8, dust can be prevented from entering the interior of the device, thereby increasing the service life of the device. By setting up the limit block 9, the slide rod 10 and the resistance spring 13, the dustproof plate 8 can be easily disassembled, making the dustproof plate 8 easier to clean. These settings increase the practicality of the device while maintaining the function of the device.

[0032] Working principle:

[0033] When the utility model is used, the module body 1 will generate heat. After the module body 1 generates heat, the heat will be conducted to the back side of the module body 1 by the heat conduction plate 4. At this time, the motor 14 is started. After the motor 14 is started, it will drive multiple turbine blades 15 to rotate. After the turbine blades 15 rotate, air will be drawn in from the circular air inlet, and then the special shape of the turbine blades 15 will send more air to the side. Before the turbine blades 15 send out the air, multiple guide and heat dissipation strips 16 have already transferred the heat on the surface of the heat conduction plate 4 to the guide and heat dissipation strips 16 themselves to the greatest extent. After the turbine blades 15 push the air, the flowing air will take away the heat from the surface of the heat conduction plate 4 and the surface of the guide and heat dissipation strips 16, and transmit it from the air outlet plate 2 to the outside of the device. In the process, most of the heat generated by the module body 1 is taken out, ensuring the quality and uniformity of heat dissipation.

[0034] By providing a motor 14 and turbine blades 15 in combination with the guide heat dissipation strips 16, the heat absorbed by the heat conducting plate 4 can be discharged evenly to the greatest extent. Compared with the existing devices, this device has a simple structure and low cost, which reduces the cost of the device while ensuring the heat dissipation effect.

[0035] During the use of the motor 14 and the turbine blades 15, dust may be driven into the device. By setting up the dustproof plate 8, dust can be filtered to prevent dust from entering the interior of the device. The dustproof plate 8 needs to be cleaned after being used for a long time. During cleaning, the pull tab 11 can be pulled. When the pull tab 11 is pulled, the slide bar 10 will be driven to move, and the other end of the slide bar 10 is fixedly connected to the limit block 9, so the limit block 9 will also be driven to move. After the two limit blocks 9 are driven to move, the one-way limit on the dustproof plate 8 will disappear. At this time, the dustproof plate 8 can be easily taken out and cleaned or replaced.

[0036] By setting up the dustproof plate 8, dust can be prevented from entering the interior of the device, thereby increasing the service life of the device. By setting up the limit block 9, the slide rod 10 and the resistance spring 13, the dustproof plate 8 can be easily disassembled, making the dustproof plate 8 easier to clean. These settings increase the practicality of the device while maintaining the function of the device.
