Description

Technical Field

[0001] The present invention relates to the technical field of display screen housing, and in particular to a display screen with distributed heat dissipation function. Background Technology

[0002] The display screen is a high-resolution screen. Because it has more pixels, each pixel has a corresponding light-emitting element or control circuit behind it, which leads to an increase in overall energy consumption and generates more heat. If the heat is not dissipated in time or the heat dissipation effect is not good, it may cause performance degradation or hardware damage.

[0003] Currently, it is more common to dissipate heat through a cooling fan. There are two main ways of dissipating heat. One is the exhaust mode, in which a cooling fan is placed inside the display housing, and then the hot air accumulated in the display is extracted. For example, the patent with the authorization announcement number CN214757543U discloses a display screen with a heat dissipation function, including a display housing, a display back shell is arranged at the rear end of the display housing, a display screen, a circuit board and a heat sink are arranged inside the display housing, a fan box, a fan controller and an intelligent controller are arranged at the rear end of the heat sink, an electric rotating shaft and fan blades are arranged inside the fan box, a ventilation hole is arranged at the front end of the fan box, and a switch is arranged at the right end of the display housing. The fan controller is used to control the fan to start to dissipate heat from the display screen. This method relies on the pressure difference between the inside and outside of the chassis and natural convection to inhale fresh air to supplement the extracted hot air, which may cause a certain positive pressure to form inside the chassis, slowing down the natural inflow speed of fresh cold air, which means that it takes a certain amount of time for the heat to be effectively diffused into the environment, that is, the heat dissipation method of the exhaust mode has the problem of slow heat dissipation speed.

[0004] The other is the intake mode, where the cooling fan is placed outside the display housing, and then cool air is blown directly to the display, which can directly take away the heat near the heat source, forming an effective heat exchange and accelerating local heat dissipation. It can be seen that this method can more directly cool the heat source quickly and improve the heat dissipation efficiency. However, although it solves the problem of slow heat dissipation in the exhaust mode, it is easy to dissipate the heat in the directly blown part, thus causing the problem of local heat dissipation, and there is a problem that the incoming gas is not easy to be discharged, causing the heat to easily accumulate inside the display housing and the display.

[0005] In order to quickly dissipate the heat of the display screen and dissipate the heat as a whole to prevent heat from accumulating inside the display screen, the present invention proposes a display screen with distributed heat dissipation function. SUMMARY OF THE INVENTION

[0006] In order to overcome the shortcomings of local heat dissipation and heat accumulation, the present invention provides a display screen with distributed heat dissipation function.

[0007] A display screen with a distributed heat dissipation function, comprising a base, the base is rotatably connected with a housing, the front side of the housing is fixedly connected with a display screen, at least one sliding plate is slidably connected to the back side of the housing in the front-rear direction, a fan is rotatably connected in the sliding plate, and a plurality of heat dissipation holes are opened on the upper, lower, left and right sides of the housing for discharging heat from the upper, lower, left and right sides of the housing. A guiding component for diffusing natural wind is fixedly connected in the housing;

[0008] The guiding component includes connecting plates symmetrically distributed along the left and right of the housing. The connecting plates are fixedly connected to one side of the housing close to the fan. A first guiding plate is fixedly connected between the symmetrically distributed connecting plates. The first guiding plate is fixedly connected with second guiding plates symmetrically distributed along the upper and lower of the first guiding plate.

[0009] In addition, particularly preferably, a filter screen is further included, and the filter screen is fixedly connected to the side of the sliding plate away from the display screen.

[0010] In addition, particularly preferably, the first guiding plate is provided with guiding grooves symmetrically distributed left and right for guiding natural wind to the left and right sides respectively. The second guiding plates symmetrically distributed up and down are both provided with guiding grooves. The guiding groove of the upper second guiding plate is used for guiding natural wind to the upper side, and the guiding groove of the lower second guiding plate is used for guiding natural wind to the lower side.

[0011] In addition, particularly preferably, a first rotating shaft is further included. The first rotating shaft is rotatably connected to the housing. A first motor is fixedly connected to one side of the housing close to the cover plate. The output shaft of the first motor is fixedly connected with the first rotating shaft, and the first rotating shaft is fixedly connected with the cover plate.

[0012] In addition, particularly preferably, connecting rods symmetrically distributed along the left and right sides of the cover plate are further included. One end of the connecting rod is rotatably connected with the cover plate. A slider is slidably connected to the sliding plate, and the slider is rotatably connected with the other end of the adjacent connecting rod.

[0013] In addition, particularly preferably, two second motors are further included. The second motors are fixedly connected to the inside of the housing. The output shafts of the second motors are fixedly connected with second rotating shafts. The second rotating shafts are rotatably connected with the housing. The second rotating shafts are fixedly connected with fan blades for accelerating the dissipation of heat.

[0014] In addition, particularly preferably, slope-shaped structures for blocking the reverse flow of air are arranged on both sides of the housing close to the fan blades.

[0015] In addition, particularly preferably, a guiding opening is opened on one side of the housing close to the lower fan blade.

[0016] In addition, it is particularly preferred that a hollow air guide frame is further included. The air guide frame is fixedly connected to one side of the housing close to the diversion port, and the air guide frame communicates with the diversion port. One side of the housing close to the air guide frame is fixedly connected with a heat-conducting copper plate for dissipating heat from the display screen. One side of the heat-conducting copper plate close to the air guide frame is located outside the housing. The hot air dissipated through the air guide frame exchanges heat in the air and is cooled into natural wind, which blows towards the heat-conducting copper plate to dissipate heat from the heat-conducting copper plate.

[0017] In addition, it is particularly preferred that the air guide frame is inclined, and the heat-conducting copper plate is parallel to the air guide frame, and the heat-conducting copper plate is located above the air guide frame.

[0018] The beneficial effects of the present invention are as follows:

[0019] The present invention dissipates heat in an intake mode through a fan. During the heat dissipation process, the natural wind is respectively guided to the upper and lower sides by the first diversion plates on the upper and lower sides, and the natural wind is respectively guided to the left and right sides by the second diversion plates on the left and right sides, so that the heat dissipation direction is more comprehensive. Moreover, through the heat dissipation holes on the upper, lower, left, and right sides, the heat dissipation is accelerated. In this way, while ensuring rapid heat dissipation, the problems of local heat dissipation and heat accumulation are avoided.

[0020] The present invention is shielded by a cover plate to prevent small flying insects, dust, etc. from entering the housing when not in use. Moreover, when the cover plate is closed, the cover plate drives the sliding plate to automatically move outwards through a connecting rod, realizing the automatic storage of the sliding plate and the fan. When the cover plate is opened, the fan is automatically pushed out to expand the heat dissipation range.

[0021] The present invention assists in heat dissipation through the diversion port and the heat-conducting copper plate. At the same time, the hot air flow dissipated through the diversion port is introduced into the air along the air guide frame, exchanges heat and is cooled into natural wind, which blows towards the heat-conducting copper plate to dissipate heat from the heat-conducting copper plate. In this way, the secondary application of the air flow is realized, further accelerating the heat dissipation of the display screen with a distributed heat dissipation function.

Detailed implementation manners

[0037] The above solutions are further described below in conjunction with specific embodiments. It should be understood that these embodiments are for illustrating the present application and not for limiting the scope of the present application. The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually those in conventional experiments.

[0038] Embodiment 1: A display screen with a distributed heat dissipation function, combined with the attached Figure 1 to the attached Figure 7 , including a base 101. The upper part of the base 101 is rotatably connected to a housing 102. The front side of the housing 102 is fixedly connected to a display screen 1021. Two sliding plates 103 are slidably connected to one side of the housing 102 away from the display screen 1021 in the front-back direction. A fan 104 for heat dissipation is rotatably connected inside the sliding plate 103. A filter screen 105 is fixedly connected to the rear side of the sliding plate 103. A plurality of heat dissipation holes 106 are opened on the upper, lower, left, and right sides of the housing 102 to discharge heat from the upper, lower, left, and right sides of the housing 102, avoiding heat accumulation inside. A connecting plate 203 symmetrically distributed along the left and right sides of the housing 102 is fixedly connected to one side of the housing 102 close to the fan 104. A first deflector plate 201 is fixedly connected between the symmetrically distributed connecting plates 203 on the left and right. The first deflector plate 201 is provided with deflection grooves distributed symmetrically left and right for guiding natural wind to the left and right sides respectively. A second deflector plate 202 symmetrically distributed along the upper and lower sides of the first deflector plate 201 is fixedly connected to the first deflector plate 201. The sliding plate 103 and the fan 104 are both located at the rear side of the first deflector plate 201, the second deflector plate 202, and the connecting plate 203, and there is enough space for the sliding plate 103 and the fan 104 to move at the rear side of the first deflector plate 201, the second deflector plate 202, and the connecting plate 203. The symmetrically distributed second deflector plates 202 on the upper and lower sides are both provided with deflection grooves. The deflection groove of the upper second deflector plate 202 is used to guide natural wind to the upper side, and the deflection groove of the lower second deflector plate 202 is used to guide natural wind to the lower side.

[0039] This is a display screen with distributed heat dissipation. Initially, the sliding plate 103 and the fan 104 are both housed inside the housing 102. When the display screen 1021 needs to be used, since the distance between the fan 104 and the display screen 1021 is relatively close at this time and the heat dissipation range is small, in order to expand the heat dissipation range, the sliding plate 103 needs to be slid to the side away from the display screen 1021, thereby driving the fan 104 to move to the side away from the display screen 1021. Subsequently, the fan 104 is started. The fan 104 guides natural wind into the interior of the housing 102. The heat dissipated by the display screen 1021 is exchanged with the incoming natural wind. The hot air inside the housing 102 is then dissipated into the air through the heat dissipation holes 106 on the upper, lower, left, and right sides. In this way, the effect of distributed heat dissipation for the display screen 1021 is achieved. The filter screen 105 can filter dust and avoid too much dust entering the interior of the housing 102. During the heat dissipation process, the first deflector plates 201 on the upper and lower sides respectively guide natural wind to the upper and lower sides, and the second deflector plates 202 on the left and right sides respectively guide natural wind to the left and right sides, making the heat dissipation orientation more comprehensive. Moreover, the heat dissipation holes 106 on the upper, lower, left, and right sides can accelerate the dissipation of heat. In this way, while ensuring rapid heat dissipation, the problems of local heat dissipation and heat accumulation are avoided.

[0040] Combined with Figure 8 To Attachment Figure 10 , further comprising a first rotating shaft 303, the first rotating shaft 303 is rotatably connected to the housing 102, a first motor 302 is fixedly connected to the side of the housing 102 close to the cover plate 301, the output shaft of the first motor 302 is fixedly connected to the first rotating shaft 303, the first rotating shaft 303 is fixedly connected to the cover plate 301, the cover plate 301 is rotatably connected to connecting rods 304 symmetrically distributed along the left and right sides of the cover plate 301, a slider 305 is slidably connected to the side of the sliding plate 103 close to the adjacent connecting rod 304 in the up and down direction, and the slider 305 is rotatably connected to the adjacent connecting rod 304.

[0041] In order to prevent tiny flying insects, dust, etc. from entering the housing 102 when not in use, it is necessary to block it with the cover 301. When in use, the first motor 302 is controlled to drive the first rotating shaft 303 to rotate, thereby driving the cover 301 to rotate, so that the cover 301 automatically opens, which does not affect the entry of natural wind. When the cover 301 is opened, the cover 301 drives the sliding plate 103 to move outward automatically through the connecting rod 304, without manually pushing the sliding plate 103 outward. When the use is completed, the first motor 302 is controlled to drive the first rotating shaft 303 to reverse, thereby driving the cover 301 to automatically close, and at the same time, the sliding plate 103 and the fan 104 are automatically stored in the housing 102 through the connecting rod 304.

[0042] Example 2: Based on Example 1, combined with the attached Figure 11 To Attachment Figure 13 , and also includes two upper and lower second motors 401, the second motors 401 are fixedly connected to the inside of the shell 102, and the upper and lower second motors 401 are respectively close to the heat dissipation holes 106 on the upper and lower sides, the output shaft of the second motor 401 is fixedly connected to the second shaft 402, the second shaft 402 is rotatably connected to the shell 102, and the second shaft 402 is fixedly connected to the fan blade 403, and the second motor 401 controls the rotation of the fan blade 403 through the second shaft 402 to accelerate the dissipation of heat, and the upper and lower sides of the shell 102 are provided with a retaining slope 404, and the retaining slope 404 is close to the adjacent fan blade 403, and is used to prevent the backflow of the airflow derived from the fan blade 403, and the side of the shell 102 close to the lower fan blade 403 is provided with a guide port 405 to assist in the dissipation of heat.

[0043] Combined with Figure 2 and attached Figure 14, further comprising an air guide frame 501 provided with a hollow structure. The air guide frame 501 is fixedly connected to one side of the outer shell 102 close to the diversion port 405. The air guide frame 501 communicates with the diversion port 405. One side of the outer shell 102 close to the air guide frame 501 is fixedly connected with a heat-conducting copper plate 502, and the heat-conducting copper plate 502 is used for dissipating heat from the display screen 1021. One side of the heat-conducting copper plate 502 close to the air guide frame 501 is located outside the outer shell 102. One side of the heat-conducting copper plate 502 far from the air guide frame 501 is fixedly connected to the second diversion plate 202 on the lower side, so that the internal heat can be quickly conducted to the heat-conducting copper plate 502 through the second diversion plate 202 on the lower side. The air guide frame 501 is inclined, and the heat-conducting copper plate 502 is parallel to the air guide frame 501. The heat-conducting copper plate 502 is located above the air guide frame 501. The hot air flow discharged through the diversion port 405 is introduced into the air along the air guide frame 501 for heat exchange to be cooled into natural wind and blown towards the heat-conducting copper plate 502 to dissipate heat from the heat-conducting copper plate 502. In this way, the secondary application of the air flow is realized, and the heat dissipation of the display screen with a distributed heat dissipation function is further accelerated.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
