TECHNICAL FIELD

[0001] The application relates to the technical field of display, in particular to a display with good heat dissipation effect. BACKGROUND

[0002] As a core device of information interaction, the display has been deeply integrated into multiple scenes such as office, entertainment, medical image diagnosis and industrial automation control. With the upgrading of chip process and the innovation of display technology, high-performance displays with 4K / 8K high resolution and 144Hz or more high refresh rate are popular, and the heat load generated by the internal electronic elements under high-frequency operation increases exponentially, and the heat dissipation efficiency directly restricts the stability and service life of the device.

[0003] The current mainstream heat dissipation scheme generally adopts a passive + active heat dissipation combination of a fixed back heat dissipation hole array combined with a local fan, but this structure has double technical bottlenecks: the fixed heat dissipation path makes it difficult for airflow to cover the whole domain of the circuit board with complex distribution of heat sources, and when heat is concentrated in key parts such as GPU and power module, targeted cooling cannot be achieved.

[0011] To facilitate the assembly of the guide rail, the present invention includes an improvement in which positioning plates are provided at both ends of the guide rail, and the positioning plates are fixed to the rear end of the display body by screws.

[0012] To improve the stability of the U-shaped bellows during movement, the present invention includes the following improvements: the cross-section of the cavity is rectangular, the crossbar is tightly fitted to the cavity, and the front end of the U-shaped bellows is tightly fitted to the rear end of the display body.

[0013] The inner side of the guide rail is provided with a guide groove, and a guide rod is fixedly installed in the guide groove.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a display with good heat dissipation, which has the following beneficial effects:

[0017] This invention achieves dynamic adjustment of the heat dissipation path through the linkage of a temperature sensor, a motor, and a cooling fan.

The air supply principle is the same as that of the first cooling fan, which enhances the heat exchange efficiency and forms a composite heat dissipation mode of "active air supply + passive heat dissipation", which significantly improves the heat dissipation efficiency compared with the traditional solution.

Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0028] Please refer to Figures 1-7 , a display with good heat dissipation effect, comprising a display body 1, a temperature sensor is arranged in the display body 1, and a fixed seat 6 is fixedly arranged at the rear end of the display body 1;

[0029] ​​The two guide rails 2 are symmetrically arranged on the rear end of the display body 1, and a plurality of air exchange holes 23 are arranged between the two guide rails 2; the rear end of the fixing seat 6 is provided with an air slot 7, and a motor 8 is fixedly arranged in the air slot 7; the motor 8 is provided with a motor controller; two positioning seats 13 are symmetrically arranged on the two sides of the fixing seat 6, and the positioning seats 13 are provided with cavities; the output end of the motor 8 is provided with a driving shaft 9 located in the fixing seat 6; a driven shaft 11 is rotatably arranged in the fixing seat 6; the middle part of the driven shaft 11 is provided with a driven bevel gear 12 engaged with the driving shaft 9; and the two ends of the driven shaft 11 are provided with threaded rods 14 inserted into the cavities.

[0030] The two U-shaped bellows are symmetrically arranged on the two sides of the fixing seat 6, the middle part of the U-shaped bellows is provided with a cross bar 17 inserted into the cavity, the cross bar 17 is provided with a threaded groove, the threaded rod 14 is inserted into the threaded groove and is screwed with the cross bar 17, one side of the U-shaped bellows is provided with a first cooling fan 19, the air outlet end of the first cooling fan 19 is provided with an air inlet pipe inserted into the U-shaped bellows, the lower end of the U-shaped bellows is provided with a plurality of first air outlets 24 communicated with the air exchange holes 23, and the rear end of the U-shaped bellows is further provided with a fan controller 18.

[0031] The two ends of the guide rail 2 are provided with positioning plates, and the positioning plates are fixed on the rear end of the display body 1 by screws.

[0032] The guide rail 2 is fixed on the rear end of the display body 1 by the positioning plates and the screws at the two ends, which is convenient and firm to install and convenient for later maintenance and disassembly.

[0033] The fixing seat 6 is provided with screw holes at four corners for installing a display support.

[0034] (I) Normal cooling operation:

[0035] When the display body 1 is working normally, the temperature sensor monitors the internal temperature in real time.

[0036] At this time, the motor 8 in the air slot 7 at the rear end of the fixing seat 6 is in standby state, and the U-shaped bellows is threadedly connected with the threaded rod 14 in the cavity of the positioning seat 13 through the cross bar 17, and remains stationary.

[0037] The front end of the U-shaped bellows is closely attached to the rear end of the display body 1, and the first air outlets 24 at the lower end of the U-shaped bellows are communicated with the air exchange holes 23 between the two guide rails 2 at the rear end of the display body 1.

[0038] At the same time, the first cooling fan 19 on one side of the U-shaped bellows may be in a low-speed running state under the regulation of the fan controller 18, external air is introduced into the U-shaped bellows through the air inlet pipe, and then is sent into the display body 1 through the first air outlets 24 and the air exchange holes 23, to form a basic cooling air flow.

[0039] The rear end of the guide rail 2 is fixedly provided with a heat dissipation fin 3, and the two ends of the U-shaped air bellow are provided with auxiliary heat dissipation boxes 20. The side of the auxiliary heat dissipation box 20 close to the heat dissipation fin 3 is provided with a second air outlet hole 21, and the side of the auxiliary heat dissipation box 20 away from the heat dissipation fin 3 is provided with a second heat dissipation fan 22. The air outlet end of the second heat dissipation fan 22 is in communication with the second air outlet hole 21.

[0040] The heat dissipation fin 3 at the rear end of the guide rail 2 is in natural convection with air, thereby assisting in dissipating the heat of the display main body 1. The second heat dissipation fan 22 on the side of the auxiliary heat dissipation box 20 away from the heat dissipation fin 3 can be in standby or low-speed operation state, and the air outlet end thereof is in communication with the second air outlet hole 21 on the side close to the heat dissipation fin 3. However, at this time, the air flow is weak, and mainly relies on natural heat dissipation.

[0041] (Three) intelligent temperature control heat dissipation start:

[0042] When the temperature sensor detects that the temperature in the display main body 1 exceeds the rated value, the motor controller and the fan controller 18 are triggered by electric signal:

[0043] The motor 8 drives the U-shaped air bellow to move: after the motor 8 is started, the driving shaft 9 at the output end of the motor 8 drives the driving bevel gear 10 to rotate, the driven bevel gear 12 meshing with the driving bevel gear 10 rotates in turn, thereby driving the driven shaft 11 to rotate.

[0044] The two sides of the fixed seat 6 are inlaid with two bearings, the two ends of the driven shaft 11 penetrate through the bearings and are in rotating connection with the bearings, the output end of the motor 8 is provided with a driving shaft 9 inserted into the inside of the fixed seat 6, and the driving bevel gear 10 is fixed at the bottom end of the driving shaft 9.

[0045] The cross section of the cavity is rectangular, the cross bar 17 is closely attached to the cavity, and the front end of the U-shaped air bellow is closely attached to the rear end of the display main body 1.

[0046] The threaded rods 14 at the two ends of the driven shaft 11 rotate in the cavity of the positioning seat 13. Since the threaded groove in the cross bar 17 is in threaded connection with the threaded rod 14, and the cross bar 17 is closely attached to the cavity with a rectangular cross section (limiting the rotation of the cross bar 17), the rotation of the threaded rod 14 is converted into the linear movement of the cross bar 17 along the cavity, thereby pushing the U-shaped air bellow to move at the rear end of the display main body 1.

[0047] The inner side of the guide rail 2 is provided with a guide groove 4, the guide groove 4 is fixedly provided with a guide rod 5, the two ends of the U-shaped air bellow are provided with guide blocks 16 inserted into the inside of the guide groove 4 and in sliding fit with the guide groove 4, the guide blocks 16 are penetrated by the guide rod 5 and in sliding fit with the guide rod 5.

[0048] The guide blocks 16 are in sliding fit with the guide groove 4 and are penetrated by the guide rod 5, which ensures that the U-shaped air bellow is stable and free of shaking during movement, and avoids deviation.

[0049] The first cooling fan 19 runs at high speed, injects strong air flow into the U-shaped air box through the air inlet pipe, blows to the inside of the display main body 1 through the first air outlet hole 24 and the air exchange hole 23, and accelerates air circulation; at the same time, the second cooling fan 22 on the auxiliary cooling box 20 starts to blow external air to the cooling fins 3 through the second air outlet hole 21, enhancing the cooling efficiency of the cooling fins 3.

[0050] (Three) Dynamic global cooling process:

[0051] The U-shaped air box reciprocates or moves to a fixed point along the guide rail 2 under the drive of the motor 8:

[0052] Global uniform cooling: when the temperature distribution in the display main body 1 is relatively uniform, the motor 8 drives the U-shaped air box to move at different air exchange holes 23, and the first air outlet hole 24 is aligned with the air exchange hole 23 in different areas as the position of the U-shaped air box changes, so that the air flow covers the entire area inside the display main body 1, avoiding heat accumulation.

[0053] Precise point cooling: if a temperature sensor is installed at a high-temperature part (such as GPU, power module) in the display main body 1, when the temperature of the part exceeds the standard, the motor controller drives the U-shaped air box to move to the air exchange hole 23 behind the temperature sensor, so that the first air outlet hole 24 accurately aligns with the high-temperature area, achieving targeted cooling.

[0054] (Four) Cooling ends and resets:

[0055] When the temperature sensor detects that the temperature in the display main body 1 drops below the rated value, the motor controller turns off the motor 8, and the U-shaped air box stops moving; the fan controller 18 reduces the speed of the first cooling fan 19 and the second cooling fan 22 or puts them on standby, the system returns to the normal cooling mode, and each part returns to the initial state, preparing for the next temperature control cooling response.

[0056] The guide groove 4 on the inner side of the guide rail 2 cooperates with the guide rod 5, the guide block 16 at both ends of the U-shaped air box slides along the guide rod 5, ensuring that the U-shaped air box does not deviate when moving, ensuring the precise docking of the first air outlet hole 24 and the air exchange hole 23, avoiding air leakage and improving cooling efficiency.

[0057] The cavity closely fits the cross bar 17, reducing the shaking and wear during movement; the bearing supports the rotation of the driven shaft 11, reducing friction loss; the front end of the U-shaped air box closely fits the rear end of the display main body 1, avoiding dust accumulation affecting cooling, and prolonging the service life of each part.

[0058] The display heat dissipation structure can adjust the heat dissipation mode according to different use scenarios: in the office scenario, normal heat dissipation can meet the demand; in the game, industrial control and other high-performance load scenarios, intelligent temperature control heat dissipation is started, and the heat source is dynamically covered to ensure the stability of the display in high load operation, suitable for office, entertainment, industrial automation and other scenarios.
