Description

TECHNICAL FIELD

[0001] The present application relates to the field of heat dissipation devices, in particular to a display intelligent heat dissipation device and method. BACKGROUND

[0002] The liquid crystal display is a flat and thin display device composed of a certain number of color or black and white pixels. When the liquid crystal display is used, it will generate a high heat, and therefore needs to be cooled. Due to work requirements, some liquid crystal displays need to be wall-mounted on the wall.

[0003] Due to the small distance between the back of the display and the wall, the back of the display lacks sufficient space for heat dissipation and cooling. If only the existing cooling method, i.e. the natural cooling method of setting a heat dissipation groove, is used, although a certain cooling can be achieved, the natural cooling cannot meet the demand in the case of accelerated temperature rise of the display due to long-time use, and the service life of the display will be shortened over time. Therefore, for the heat dissipation demand of the display in this environment, a display intelligent heat dissipation device and method are proposed. SUMMARY

[0019] Further, a plurality of metal parts are arranged on said limiting shell, said metal parts are in contact with the display to realize heat conduction, and a dust screen is arranged outside said heat sink of said heat dissipation fan.

Since one end of the hinge shaft is larger and the other end is smaller, the connection between the first connecting rod and the second connecting rod is in a relatively fixed state under the action of the thrust. Therefore, the first connecting rod and the second connecting rod form a linkage state. As long as other switching plates have closing actions, the linkage of multiple switching plates can be realized, and the purpose of synchronously closing the heat dissipation grooves of the switching assembly can be achieved, and the reliability is higher.

DETAILED DESCRIPTION

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0040] detection unit, the detection unit is used to detect the temperature of display;

[0041] control unit, for selectively controlling air cooling unit 2 work according to the detection result of the detection unit.

[0042] Further, the air cooling unit 2 includes:

[0043] The heat dissipation groove 21 is arranged on the heat dissipation shell 1, and at least two groups of the heat dissipation groove 21 are arranged on the heat dissipation shell 1 in a diagonal manner; one of the heat dissipation grooves 21 is provided with a heat dissipation fan 22, one of the heat dissipation fans 22 is used for guiding air outwards, and the other heat dissipation fan 22 is used for guiding air inwards.

[0044] The other heat dissipation grooves 21 are provided with a switching assembly 23, and the switching assembly 23 is used for closing the corresponding heat dissipation groove 21 when the two heat dissipation fans 22 work simultaneously.

[0045] The display is provided with a heat dissipation module, a detection unit in the heat dissipation module is used for detecting the temperature of the display in real time, and once the detected temperature reaches a set temperature, it indicates that the display is in a state of poor heat dissipation effect; therefore, the air cooling unit 2 is controlled to work, and the display is actively air cooled, so that the air circulation is accelerated to achieve the effect of rapid heat dissipation and cooling.

[0046] The air cooling unit 2 works as follows: in a normal state, the switching assembly 23 is in a static contraction state, so that all the heat dissipation grooves 21 are kept in an open state, thereby realizing natural cooling; when the temperature of the display rapidly rises to a first set temperature, one of the heat dissipation fans 22 is started to accelerate the air outflow or inflow, thereby accelerating the air replacement speed and achieving rapid heat dissipation; if the temperature of the display gradually decreases to a normal range, the heat dissipation fan 22 is stopped, and natural heat dissipation is realized; if the temperature continues to rise, when the temperature reaches a second set temperature, it indicates that the heat dissipation effect is still insufficient, so that two heat dissipation fans 22 are simultaneously started to accelerate the air inflow and outflow, thereby further improving the heat dissipation effect; in order to prevent other heat dissipation grooves 21 from affecting the flow rate of the air flow, the switching assembly 23 is used to close the other heat dissipation grooves 21, so that only the heat dissipation grooves 21 for accelerating the air inflow and the heat dissipation grooves 21 for accelerating the air outflow are left, thereby realizing the optimal working state of the two heat dissipation fans 22 and further improving the heat dissipation and cooling effect of the display.

[0047] Further, the switching assembly 23 comprises a sliding groove 231 arranged on one side of the heat dissipation groove 21, a sliding block 233 connected to the sliding groove 231 through a memory alloy spring 232, and a switching plate 234 connected to the sliding block 233; two adjacent switching plates 234 are connected through a linkage assembly 24.

[0048] The switching plate 234 is opened in the normal state and is closed under the action of the linkage assembly 24 when the two heat dissipation fans 22 work simultaneously.

[0049] The application provides a specific structure of the switching assembly 23, in use, in the initial state, the memory alloy spring 232 is in the contraction state, thus driving each connected switching plate 234 to be in the staggered state with the heat dissipation groove 21, thus the heat dissipation groove 21 is unobstructed, natural heat dissipation is realized, but once the two heat dissipation fans 22 work simultaneously, it indicates that the heat dissipation requirement of the display is in the high level, thus the temperature reaches the second set temperature, the memory alloy spring 232 realizes the expansion deformation after being heated, pushes the switching plate 234 to cover the heat dissipation groove 21, only leaving a group of heat dissipation grooves 21 cooperating with the heat dissipation fan 22 to work, so as to maximize the working effect of the heat dissipation fan 22; and the above-mentioned closing of the other heat dissipation grooves 21 does not need to be driven by a special driving part, only needs the memory alloy spring 232 which realizes the automatic deformation by the temperature change, which is quick and convenient, and saves power and energy.

[0050] Further, the linkage assembly 24 includes a first connecting rod 241, a second connecting rod 242 and a hinge shaft 243, the hinge shaft 243 gradually decreases in diameter towards one end of the heat dissipation shell 1, the first connecting rod 241 and the second connecting rod 242 are both provided with hinge holes 244 and are commonly sleeved on the hinge shaft 243 to form a movable connection, the first connecting rod 241 and the second connecting rod 242 are respectively hinged on the corresponding switching plate 234, and one end of the first connecting rod 241 and the second connecting rod 242 is provided with a magnet 245; the heat dissipation shell 1 is provided with an electromagnetic strip 246 at the position corresponding to the linkage assembly 24, and the magnet 245 is electrically connected with the control unit.

[0051] The present application reduces the problem caused by too many times of contraction and expansion deformation of the memory alloy spring 232, and further increases the synchronous closing action of the linkage assembly 24 on the plurality of switching plates 234, thereby improving the success rate and stability of the switching assembly 23.

[0052] Further, the heat dissipation groove 21 is arranged obliquely downward, and the oblique angle is 30-60 degrees.

[0053] Through the above arrangement, the dust in the external environment is not easy to enter the heat dissipation groove 21, and the accumulation of dust for a long time is avoided as much as possible, and the situation of blocking the heat dissipation groove 21 in a serious state is avoided.

[0054] The four corners of the heat dissipation shell 1 are provided with limiting grooves 3, the limiting grooves 3 are slidably installed with limiting blocks 4, the limiting blocks 4 and the bottom walls of the limiting grooves 3 are provided with supporting springs 5, the two limiting blocks 4 are provided with telescopic assemblies 6, and the telescopic assemblies 6 are used to adjust the distance between the two limiting blocks 4.

[0055] Further, the telescopic assembly 6 includes two symmetrical transverse grooves 61, the transverse grooves 61 are slidably installed with sliding members 62, the sliding members 62 and the transverse grooves 61 are provided with automatic telescopic rods 64, the sliding members 62 are provided with limiting stop rods 63, and the upper and lower sides of the limiting stop rods 63 are in contact with the side surfaces of the two limiting blocks 4.

Specifically, by automatically extending the automatic telescopic rod 64, the connected sliding piece 62 is pushed to move, thereby driving the limiting stop lever 63 to move. When the limiting stop lever moves outward, the limiting block 4 slides outward under the action of the supporting spring 5, so that the mounting space of the heat dissipation shell 1 increases. When the limiting stop lever 63 moves inward, the limiting block 4 compresses the supporting spring 5 to slide inward, so that the mounting space of the heat dissipation shell 1 decreases. Through the above process, the purpose of synchronously reducing or increasing the mounting space of the heat dissipation shell 1 is achieved, which increases the adaptation specification and is more convenient. Meanwhile, the metal part 7 and the dust screen 8 are used to achieve the purposes of enhancing heat conduction and dust prevention effect.
