Description

Technical Field

[0001] The invention relates to the field of liquid crystal displays, and in particular to a liquid crystal display housing which is convenient for heat dissipation. Background Art

[0002] All existing LCD monitors are assembled with sealed boxes. When the LCD monitor is working, the heat of its internal electrical components is retained in the box for a long time, and its internal temperature rises, thereby affecting the normal operation of the LCD monitor. Therefore, most LCD monitors on the market are provided with heat dissipation holes to remove heat through the circulation of gas. However, due to the flow of air at the heat dissipation holes, the air rubs against the edges of the heat dissipation holes, resulting in static electricity generated and accumulated at the heat dissipation holes. The static electricity absorbs dust and impurities in the air, making the heat dissipation holes easily blocked by dust and impurities. If they are not cleaned for a long time, dust will adhere tightly to the heat dissipation holes, increasing the difficulty of cleaning later. Summary of the invention

[0003] In order to overcome the disadvantages that static electricity accumulates at the heat dissipation holes, which causes dust to easily block the heat dissipation holes and, if not cleaned for a long time, causes dust to tightly adhere to the heat dissipation holes, increasing the difficulty of subsequent cleaning, the present invention provides a liquid crystal display housing that is easy to dissipate heat.

[0008] Optionally, it also includes absorbent cotton strips; the lower part of the display housing body and the lower T-shaped plate are fixedly connected with two absorbent cotton strips; the two absorbent cotton strips block all the flow holes I.

[0009] Optionally, a guide plate is also included; two guide plates are fixedly connected to the lower part of the display housing body and the lower T-shaped plate; each guide plate is tilted and contacts with a water-absorbing cotton strip.

[0014] The beneficial effects are: 1. The present invention utilizes the ventilation holes for alternate air intake and exhaust, so that dust impurities accumulate on the dustproof net at the air intake position in the first half of the cycle, and become the exhaust position in the second half of the cycle, that is, the dust impurities on the dustproof net can be cleaned by backblowing, thereby realizing automatic cleaning of the dustproof net, effectively extending the service life of the LCD display housing, and allowing static electricity accumulated on the dustproof net to have time to be transferred through the grounding of the display housing body, so that static electricity will not accumulate on the dustproof net, resulting in the dust impurities on the dustproof net being adsorbed by static electricity and difficult to remove.

The hot chamber 1003 is connected; all the flow holes II 1002 are connected with the heat dissipation chamber 1003 above; a suction dual-purpose pump 5 is installed in the partition chamber 1004; both ends of the suction dual-purpose pump 5 are connected with a main pipe 6; each main pipe 6 is connected with a branch pipe I7; each branch pipe I7 is installed with a solenoid valve I7001; each branch pipe I7 is connected with a heat dissipation chamber 1003 above; each main pipe 6 is connected with a branch pipe II8; each branch pipe II8 is installed with a solenoid valve II8001; each branch pipe II8 is connected with a heat dissipation chamber 1003 below.

[0021] Each ventilation hole 2001 is provided with a chamfer to increase the opening area, thereby making the air flow smoother and reducing turbulence and static electricity generated by friction.

[0022] It also includes heat dissipation fins Ⅰ9; a plurality of heat dissipation fins Ⅰ9 are fixedly connected to the rear of the display housing body 1; all the heat dissipation fins Ⅰ9 are evenly distributed in the four heat dissipation cavities 1003.

[0023] It also includes heat dissipation fins II 10; a plurality of heat dissipation fins II 10 are fixedly connected to the front of the back plate 2; all the heat dissipation fins II 10 are evenly distributed in the four heat dissipation cavities 1003; the heat dissipation fins II 10 and the heat dissipation fins I9 are arranged at intervals.

[0024] It also includes absorbent cotton strips 11; the lower part of the display housing body 1 and the lower T-shaped plate 4 are fixedly connected to two absorbent cotton strips 11 distributed on the left and right; the two absorbent cotton strips 11 block all the flow holes Ⅰ1001.

[0025] The working steps of this embodiment are: When the LCD is working normally, the electrical components on the circuit board and the display panel in the LCD will generate heat. At this time, the control starts the dual-purpose suction pump 5, and controls the opening of the left solenoid valve Ⅰ7001 and the right solenoid valve Ⅱ8001. The dual-purpose suction pump 5 extracts the air in the upper left heat dissipation cavity 1003 through the left main pipe 6 and the branch pipe Ⅰ7. The upper left heat dissipation cavity 1003 has a negative pressure, so the air in the LCD enters the upper left heat dissipation cavity 1003 through the left circulation hole Ⅱ1002, and the air in the lower left heat dissipation cavity 1003 is replenished into the LCD through the left circulation hole Ⅰ1001. At this time, the lower left heat dissipation cavity 1003 has a negative pressure, so the outside air enters the lower left heat dissipation cavity 1003 through the left ventilation hole 2001. Then the dual-purpose suction pump 5 pumps the air extracted from the upper left to the right main pipe 6 and the branch pipe Ⅰ7, and then discharges the air to the right. The air then continues to flow downward and is discharged to the outside air through the ventilation hole 2001 on the right, thus completing half of the heat dissipation process. The remaining half of the process is to control the closing of the left solenoid valve Ⅰ7001 and the right solenoid valve Ⅱ8001, open the right solenoid valve Ⅰ7001 and the left solenoid valve Ⅱ8001, and the suction dual-purpose pump 5 draws air through the right main pipe 6 and the branch pipe Ⅰ7. Finally, the air circulates in the LCD display for a circle and is discharged to the outside air from the ventilation hole 2001 on the left. At this point, the entire air-cooling heat dissipation process is completed, thereby realizing the heat dissipation of the electrical components and display panel inside the LCD display through different air intake paths, effectively avoiding air circulation through a single path, and the position of the electrical components is fixed, resulting in a good heat dissipation effect for the electrical components near the air inlet and a poor heat dissipation effect for the electrical components at the exhaust port.

[0026] Considering the method of cooling the LCD display through air circulation, it is necessary to draw air from the external environment into the LCD display, so there will be a situation where dust impurities in the air will also enter the LCD display. The dust impurities entering the LCD display will not only cause poor heat dissipation of the electrical components therein, but also cause poor contact of the electrical components. Therefore, under normal circumstances, a dustproof net 3 is set at the air inlet of the LCD display to intercept dust impurities in the air. At this time, it is also necessary to consider that during the air circulation process, the outside air is continuously sucked into the LCD display, so there is continuous air passing through the air inlet. When the air passes through the dustproof net 3, the static electricity generated by the friction between the air and the dustproof net 3, the static electricity accumulates, and also absorbs dust impurities, making the dust on the dustproof net 3 firmly adhered and difficult to clean, so that the dust impurities block the dustproof net 3, resulting in air circulation being affected, and further causing the heat dissipation of the LCD to be affected. At this time, the edge of the air exchange hole 2001 can be chamfered, such as Figure 3As shown, the area of ​​air intake and exhaust is increased to make the air flow smoother and reduce the static electricity generated by turbulence and friction. The outside air enters through the air exchange hole 2001 on the left and is discharged from the air exchange hole 2001 on the right, and then enters through the air exchange hole 2001 on the right and is discharged from the air exchange hole 2001 on the left in an alternating manner of air intake and exhaust. In the first half of the cycle, dust impurities accumulate at the dustproof net 3 at the air intake position, and become the exhaust position in the second half of the cycle, that is, the dust impurities at the dustproof net 3 can be cleaned by backblowing, thereby realizing automatic cleaning of the dustproof net 3 without manual disassembly and cleaning, effectively extending the service life of the housing of the liquid crystal display. In addition, the alternating manner of air intake and exhaust can also allow the static electricity accumulated at the dustproof net 3 to have time to be transferred to the ground through the display housing body 1, and will not accumulate on the dustproof net 3, resulting in the dust impurities on the dustproof net 3 being adsorbed by static electricity and difficult to remove.

[0027] It should also be considered that when the air circulates, the air enters from the lower part of the display housing body 1 and is then discharged from the upper part of the display housing body 1. Then, the hot air in the liquid crystal display enters the upper heat dissipation cavity 1003. Since the heat will accumulate at the upper part of the liquid crystal display, the temperature of the upper part of the liquid crystal display is higher than that of the lower part. At this time, heat dissipation fins I9 and heat dissipation fins II10 are arranged in the heat dissipation cavity 1003, and the hot air flows in an "S" shape between the heat dissipation fins I9 and the heat dissipation fins II10. Figure 4 As shown, at the same time, the heat from the upper part of the LCD is conducted to the corresponding heat sink fins I9 through the upper part of the display housing body 1, and the heat sink fins I9 then conduct the heat to the flowing hot air, and then the hot air conducts the heat to the heat sink fins II 10, and the heat sink fins II 10 then conduct the heat to the back plate 2, and the back plate 2 exchanges heat with the outside air to cooperate in cooling the LCD.

[0028] Taking into account the environmental differences in different regions and the differences in different seasons, the moisture in the air is significantly different. Therefore, it is not enough to just dustproof the ventilation hole 2001. It is also necessary to waterproof it to prevent external moisture from entering the LCD display, causing a short circuit in the LCD display, so that the electrical components are burned, and even spontaneous combustion and explosion occur. Therefore, an absorbent cotton strip 11 is added at the position of the circulation hole Ⅰ1001 to remove water and filter the air entering the LCD display. When exhausting through the heat dissipation cavity 1003 below, the absorbent cotton strip 11 is blocked at the position of the circulation hole Ⅰ1001, effectively reducing the hot air discharged through the branch pipe Ⅱ8 from flowing back to the inside of the LCD through the circulation hole Ⅰ1001 when moving downward, thereby reducing the heat dissipation effect of the LCD display.

[0029] Second embodiment On the basis of the first embodiment, according to Figure 1-Figure 2and Figure 6-Figure 9 As shown, it also includes a guide plate 12; the lower part of the display housing body 1 and the lower T-shaped plate 4 are fixedly connected to two guide plates 12 distributed left and right; each guide plate 12 is tilted and contacts with a water-absorbing cotton strip 11.

[0030] The longitudinal section of the absorbent cotton strip 11 is triangular, and the guide plate 12 is inclined to increase the contact area between the absorbent cotton strip 11 and the air and absorb sufficient moisture in the air.

[0031] It also includes a heat conducting sheet 13; a plurality of heat conducting sheets 13 are arranged on the side of each guide plate 12 facing the absorbent cotton strip 11; each absorbent cotton strip 11 is plugged into and matched with the corresponding heat conducting sheet 13; a plurality of exhaust holes 1201 are horizontally opened on the upper part of each guide plate 12; the display housing body 1, the upper part of the guide plate 12 and the upper part of the absorbent cotton strip 11 form a cavity with a triangular longitudinal section, and the exhaust holes 1201 are located at the position of the triangular cavity.

[0032] The longitudinal section of the heat conducting sheet 13 is triangular and consistent with the longitudinal section shape of the absorbent cotton strip 11 , and is used to conduct heat to the absorbent cotton strip 11 more fully and evaporate the water in the absorbent cotton strip 11 .

[0033] It also includes a sealing film 14; a plurality of sealing films 14 equidistantly distributed are fixedly connected to one side of the lower part of the display housing body 1 away from the back plate 2; each sealing film 14 corresponds to a flow hole Ⅰ1001; the sealing film 14 is fixed at the top and movable at the bottom; the sealing film 14 is used to block the corresponding flow hole Ⅰ1001.

[0034] The working steps of this embodiment are: It can be seen from the above embodiment that the function of the absorbent cotton strip 11 is to absorb moisture in the air. Therefore, after the absorbent cotton strip 11 absorbs a certain amount of moisture, the water absorption performance of the absorbent cotton strip 11 decreases, and it is unable to effectively absorb and filter the moisture in the air. Therefore, the guide plate 12 and the heat conductive plate 13 are added at this time. The hot air discharged from the branch pipe II 8 moves downward and passes through the inclined guide plate 12. The hot air heats the guide plate 12. The guide plate 12 transmits the heat to the absorbent cotton strip 11 through the heat conductive plate 13, thereby heating the absorbent cotton strip 11, and then the moisture in the absorbent cotton strip 11 is evaporated, and then the evaporated water vapor gathers upward in the triangular cavity above the absorbent cotton strip 11, and this space is also provided with an exhaust hole 1201. Figure 8As shown, the exhaust hole 1201 is opened horizontally. When the downwardly flowing air passes through the guide plate 12, the flow direction of the air is changed and the air flows along the surface of the guide plate 12. Therefore, the flow speed of the air on the side of the guide plate 12 away from the absorbent cotton strip 11 is greater than the flow speed on the side of the guide plate 12 close to the absorbent cotton strip 11. Therefore, according to the Bernoulli principle, the fluid has a low pressure at a location with a high flow rate. Therefore, the water vapor in the triangular cavity above the absorbent cotton strip 11 is pressed out from the exhaust hole 1201, and moves with the hot air on the surface of the guide plate 12, and finally flows out from the ventilation hole 2001 is discharged into the air, thereby realizing heat recovery and utilization, and also automatically dehydrates the absorbent cotton strip 11. There is no need for manual participation in replacing or dehydrating the absorbent cotton strip 11, which effectively increases the service life of the liquid crystal display. At the same time, in order to prevent the water vapor evaporated from the absorbent cotton strip 11 from entering the interior of the liquid crystal display through the circulation hole Ⅰ1001, a one-way opening sealing film 14 is provided at the position of the circulation hole Ⅰ1001. Only when the suction dual-purpose pump 5 starts to pump air, the lower part of the sealing film 14 rises, and air can enter the liquid crystal display through the circulation hole Ⅰ1001.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
