Description

Technical Field

[0001] This utility model relates to a heat dissipation structure, specifically a heat dissipation structure for a liquid crystal display. Background Technology

[0002] With the development of modern information technology, people's demand for large-screen multimedia information display and human-computer interaction is becoming increasingly strong. Due to the advantages of LCD monitors such as portability, low power consumption, bright colors, and fine pixels, they have become the preferred display screen for multimedia human-computer interaction.

[0003] However, LCD screens are currently susceptible to the effects of ambient temperature during use. In summer, when the weather or working environment is too hot, the heat between the screens cannot be dissipated naturally through heat dissipation alone, resulting in even higher temperatures and potentially causing the screen to go black. Utility Model Content

[0004] The purpose of this invention is to provide a heat dissipation structure for a liquid crystal display to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A heat dissipation structure for a liquid crystal display includes an air inlet pipe and an air outlet pipe disposed at heat dissipation holes at the top and bottom of the liquid crystal display. The air inlet pipe and the air outlet pipe are fixedly installed to the housing of the liquid crystal display and are connected by a connecting pipe. A first cooling fan is fixedly installed inside the air inlet pipe. An insertion port is provided on the connecting pipe, and a first heat-conducting fin is inserted into the insertion port. A second heat-conducting fin is provided on the outer side of the first heat-conducting fin, and a semiconductor cooling chip is sandwiched between the second heat-conducting fin and the first heat-conducting fin. A second cooling fan is fixedly installed on the second heat-conducting fin.

[0007] As a further embodiment of this utility model: the ports of the air inlet pipe and the air outlet pipe are both open, and a movable pipe adapted to them is slidably inserted into the ports of the air inlet pipe and the air outlet pipe. A sealing plate is fixedly connected to the end of the movable pipe, and the sealing plate is adapted to the ports of the air inlet pipe and the air outlet pipe.

[0008] As a further improvement of this utility model: an adjusting bolt is threaded through the sealing plate, the end of the adjusting bolt is rotatably connected to the cross, and the cross is fixedly connected to the corresponding air inlet pipe and air outlet pipe.

[0009] As a further improvement of this utility model: a dust filter and a breathable mesh are respectively embedded in the middle and end of the movable tube, and the breathable mesh corresponds to and is adapted to the connecting tube.

[0010] As a further embodiment of this utility model: the first heat-conducting fin and the second heat-conducting fin are fixedly installed to the connecting pipe by bolts. The fin of the first heat-conducting fin is arranged vertically along the connecting pipe, and the fin of the second heat-conducting fin is arranged horizontally perpendicular to the first heat-conducting fin.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses a semiconductor cooling chip to create a heat pump. A second cooling fan, in conjunction with a second heat-conducting fin, dissipates heat from the hot side of the semiconductor cooling chip, maintaining its working effect. Meanwhile, the first heat-conducting fin dissipates cold energy from the cold side of the semiconductor cooling chip. This, along with the first cooling fan, air inlet pipe, air outlet pipe, and connecting pipe, circulates the air inside the liquid crystal display. The first heat-conducting fin allows for heat exchange with the surrounding space, achieving active cooling. This ensures that the internal components of the liquid crystal display are cooled, and the entire display circulates cool air internally without contacting the outside environment, effectively avoiding the influence of ambient temperature.

[0013] 2. This utility model can adjust the position of the sealing plate and the movable tube by adjusting the rotation of the bolt, control the connection state of the connecting pipe with the air inlet pipe and the air outlet pipe, and control the open state of the ports of the air inlet pipe and the air outlet pipe. In this way, it can work with the first cooling fan to ventilate and dissipate heat to the LCD screen, which is convenient for ventilation and heat dissipation when the ambient temperature is low, and reduces energy consumption compared to active cooling.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-3 In this embodiment of the present invention, a heat dissipation structure for a liquid crystal display includes an air inlet pipe 2 and an air outlet pipe 3 disposed at the top and bottom heat dissipation holes of the liquid crystal display 1. The air inlet pipe 2 and the air outlet pipe 3 are both fixedly installed to the housing of the liquid crystal display 1. The air inlet pipe 2 and the air outlet pipe 3 are connected by a connecting pipe 4. A first cooling fan 5 is fixedly installed inside the air inlet pipe 2. An insertion port 6 is provided on the connecting pipe 4. A first heat-conducting fin 7 is inserted into the insertion port 6. A second heat-conducting fin 8 is provided on the outer side of the first heat-conducting fin 7. A semiconductor cooling chip 9 is sandwiched between the second heat-conducting fin 8 and the first heat-conducting fin 7. A second cooling fan 10 is fixedly installed on the second heat-conducting fin 8.

[0020] A heat pump is used by a thermoelectric cooler 9. The second cooling fan 10, in conjunction with the second heat-conducting fins 8, dissipates heat from the hot side of the thermoelectric cooler 9 to maintain its working effect. Meanwhile, the first heat-conducting fins 7 conduct cold energy from the cold side of the thermoelectric cooler 9. This, along with the first cooling fan 5, the air inlet pipe 2, the air outlet pipe 3, and the connecting pipe 4, circulates the air inside the liquid crystal display 1. The first heat-conducting fins 7 then contact the space for heat exchange, thereby achieving active cooling. This ensures that the liquid crystal display 1 is cooled internally, with the entire system circulating cool air without contact with the outside, effectively avoiding the influence of ambient temperature.

[0021] Both the inlet pipe 2 and the outlet pipe 3 have open ports. A movable pipe 11 adapted to the port of the inlet pipe 2 and the outlet pipe 3 is slidably inserted into the port of the inlet pipe 2 and the outlet pipe 3. A sealing plate 12 is fixedly connected to the end of the movable pipe 11 and is adapted to the port of the inlet pipe 2 and the outlet pipe 3.

[0022] An adjusting bolt 16 is threaded through the sealing plate 12. The end of the adjusting bolt 16 is rotatably connected to the cross 13, and the cross 13 is fixedly connected to the corresponding air inlet pipe 2 and air outlet pipe 3.

[0023] The middle and end of the movable tube 11 are respectively fitted with a dust filter 14 and a breathable mesh 15, and the breathable mesh 15 corresponds to and is adapted to the connecting tube 4.

[0024] The first heat-conducting fin 7 and the second heat-conducting fin 8 are fixedly installed to the connecting pipe 4 by bolts. The fins of the first heat-conducting fin 7 are vertically arranged along the connecting pipe 4, while the fins of the second heat-conducting fin 8 are horizontally arranged perpendicular to the first heat-conducting fin 7. The vertical arrangement of the first heat-conducting fin 7 forms a vertical channel within the connecting pipe 4, facilitating sufficient heat exchange with the air. The horizontal arrangement of the second heat-conducting fin 8 forms a horizontal ventilation channel. When the second cooling fan 10 blows air for heat dissipation, the air diffuses to both sides, avoiding being blocked by the outward-extending ends of the air inlet pipe 2 and the air outlet pipe 3, thus preventing the diffusion of hot air.

[0025] The first cooling fan 5, the semiconductor cooling chip 9, and the second cooling fan 10 are all externally connected to power supplies and switches.

[0026] By adjusting the rotation of the bolt 16, the position of the sealing plate 12 and the movable tube 11 can be adjusted, controlling the connection state between the connecting tube 4 and the air inlet tube 2 and the air outlet tube 3, and simultaneously controlling the open state of the ports of the air inlet tube 2 and the air outlet tube 3. This allows for ventilation and heat dissipation to the LCD display 1 in conjunction with the first cooling fan 5, thus facilitating ventilation and heat dissipation when the ambient temperature is low, reducing energy consumption compared to active cooling.

[0027] By adjusting the rotation of the adjusting bolt 16, the positions of the sealing plate 12 and the movable tube 11 can be adjusted. During the adjustment process, the outer wall of the dust filter 14 slides into contact with the inner edge of the port of the air inlet pipe 2, thereby achieving the effect of cleaning the surface of the dust filter 14.

[0028] A dust filter 14 is installed at the outer port of the active tube 11 to achieve the effect of dust prevention and isolation, and to prevent a large amount of dust from entering the interior of the LCD display 1 during ventilation and heat dissipation.

[0029] The working principle of this utility model is as follows:

[0030] In use, by rotating the adjusting bolt 16, the positions of the sealing plate 12 and the movable tube 11 can be adjusted so that the sealing plate 12 seals the ports of the air inlet pipe 2 and the air outlet pipe 3. At this time, the vent mesh 15 corresponds to the end of the connecting pipe 4, forming a connecting channel. This allows the air inlet pipe 2, the air outlet pipe 3, and the connecting pipe 4 to form an internal circulation with the interior of the LCD display 1. The semiconductor cooling chip 9 acts as a heat pump, and the second cooling fan 10, in conjunction with the second heat-conducting fin plate 8, dissipates heat from the hot surface of the semiconductor cooling chip 9, maintaining the working effect of the semiconductor cooling chip 9. The first heat-conducting fin plate 7 then conducts cold energy from the cold surface of the semiconductor cooling chip 9. This, in conjunction with the first cooling fan 5, the air inlet pipe 2, the air outlet pipe 3, and the connecting pipe 4, circulates the air inside the LCD display 1. The first heat-conducting fin plate 7 then contacts the space for heat exchange, thereby achieving active cooling. This allows the interior of the LCD display 1 to be cooled, and the overall cold air circulates internally without contacting the outside, effectively avoiding the influence of ambient temperature.

[0031] By adjusting the rotation of the adjusting bolt 16, the positions of the sealing plate 12 and the movable tube 11 can be adjusted, causing the ventilated mesh 15 to be misaligned with the connecting tube 4. Thus, the movable tube 11 closes the port of the connecting tube 4. At this time, the dust filter 14 extends out from the ports of the air inlet pipe 2 and the air outlet pipe 3. The sealing plate 12 loosens its seal on the air inlet pipe 2 and the air outlet pipe 3. At this time, the air inlet pipe 2 and the air outlet pipe 3 are connected to the outside through the movable tube 11 and the dust filter 14. This allows the first cooling fan 5 to work together to ventilate and cool the LCD display 1, which is convenient for ventilation and cooling when the ambient temperature is low, thus reducing energy consumption compared to active cooling.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
