Abstract
Description
Technical Field
[0001] This utility model relates to the field of display technology, and specifically to a backlit heat dissipation display. Background Technology
[0002] The main reason for monitor heat dissipation is that monitors generate heat during operation. If this heat is not dissipated in time, it can lead to overheating, affecting its performance and lifespan. When a monitor is working, its internal electronic components, such as the power supply and driver chips, generate heat. If this heat is not dissipated in time, the component temperature will rise, affecting its normal operation. Backlight heat: The backlight in an LCD monitor also generates heat during operation. The backlight generates a significant amount of heat, and if not effectively dissipated, it may shorten its lifespan. Circuit board heat: The circuit boards in a monitor also generate heat when current flows through them. Excessive circuit board temperature will affect its stability and reliability.
[0003] Current monitor cooling typically involves an internal cooling fan and numerous ventilation holes. The fan accelerates airflow within the monitor, quickly transferring heat to the outside. However, this design easily leads to dust accumulation both inside and within the ventilation holes. This accumulated dust is difficult to clean, ultimately causing heat to accumulate in the dust, or the ventilation holes to become blocked, preventing effective heat dissipation. Utility Model Content
[0004] In view of the fact that dust easily accumulates in the heat dissipation holes of current backlit heat dissipation displays and is difficult to clean, thus affecting heat dissipation, this application provides a backlit heat dissipation display to solve the above problems.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] This application discloses a backlit heat dissipation display, including a display body. A heat dissipation backplate structure is provided on the back of the display body. The heat dissipation backplate structure includes a first heat dissipation cover and a second heat dissipation cover. The second heat dissipation cover is nested outside the first heat dissipation cover and can move along the inner and outer sides of the first heat dissipation cover. A first heat dissipation protrusion is fixed on the outer side of the first heat dissipation cover. The first heat dissipation protrusion has a first heat dissipation hole that penetrates the first heat dissipation cover. A second heat dissipation protrusion is fixed on the inner side of the second heat dissipation cover. The second heat dissipation protrusion has a second heat dissipation hole that penetrates the second heat dissipation cover. The second heat dissipation protrusion is nested outside the first heat dissipation protrusion. The second heat dissipation protrusion moves along the first heat dissipation protrusion to clean the dust on the inner side of the second heat dissipation protrusion.
[0007] Optionally, the first and second heat dissipation protrusions are arranged in m rows respectively. The form is in the form of n columns, where the number of m columns is greater than 12 and the number of n columns is greater than 10.

[0013] Technical effects:
[0014] This utility model provides a backlit heat dissipation display, which separates the heat dissipation backplate structure of the back of the display into a first heat dissipation cover and a second heat dissipation cover, and the heat dissipation holes on the first heat dissipation cover and the second heat dissipation cover are respectively designated as first heat dissipation holes and second heat dissipation holes. When it is necessary to dissipate dust from the heat dissipation holes, the second heat dissipation protrusion moves along the first heat dissipation protrusion, and the second heat dissipation protrusion can push out all the dust accumulated in the holes of the first heat dissipation protrusion, so as to facilitate and quickly clean the dust accumulated in the heat dissipation holes on the back of the display, thereby achieving efficient heat dissipation.

However, it will be apparent to those skilled in the art that the present application may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid obscuring the description of the present application with unnecessary detail.
[0021] It should be understood that, when used in this application specification and the appended claims, the term "comprising" indicates the presence of the described features, integrals, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or a collection thereof.
[0022] Please see Figure 1-Figure 2Traditional backlit heat dissipation displays typically dissipate heat through ventilation holes and internal cooling fans. However, the ventilation holes can accumulate dust, which is difficult to clean and can easily become clogged, affecting heat dissipation. To address these issues, this application provides a backlit heat dissipation display, including a display body with an internal cooling fan. A heat dissipation backplate structure 1 is located on the back of the display body. The backplate structure 1 includes a first heat dissipation cover 2 and a second heat dissipation cover 3. The second heat dissipation cover 3 is nested outside the first heat dissipation cover 2 and can move along the inner and outer sides of the first heat dissipation cover 2. A first heat dissipation protrusion 4 is fixed to the outer side of the first heat dissipation cover 2, and a first heat dissipation hole 5 is formed on the first heat dissipation protrusion 4 and penetrates the first heat dissipation cover 2. A second heat dissipation protrusion 6 is fixed to the inner side of the second heat dissipation cover 3, and a second heat dissipation hole 7 is formed on the second heat dissipation protrusion 6 and penetrates the second heat dissipation cover 3. The second heat dissipation protrusion 6 is nested outside the first heat dissipation protrusion 4, and its movement along the first heat dissipation protrusion 4 allows for cleaning of dust from its inner side. It is worth mentioning that, by adopting the above technical solution, when the heat dissipation protrusions on the outside are blocked, the second heat dissipation cover 3 can be moved along the first heat dissipation cover 2, thereby driving the first heat dissipation protrusion 4 to move along the inner wall of the second heat dissipation protrusion 6, thereby pushing out all the dust in the second heat dissipation protrusion 6, and preventing the problem of low heat dissipation efficiency of the backlight display due to the accumulation of dust.
[0023] The first heat dissipation protrusion 4 and the second heat dissipation protrusion 6 are respectively arranged in m rows. The design uses n columns, where m is greater than 12 and n is greater than 10. This design enables heat dissipation through sufficient ventilation gaps while effectively blocking most of the dust in the air.
[0024] The first heat dissipation protrusion 4 and the second heat dissipation protrusion 6 are respectively arranged in a concentric circle arrangement from the inside to the outside, and the number of the first heat dissipation protrusion 4 or the second heat dissipation protrusion 6 on the innermost side is ≥1, and the number of the first heat dissipation protrusion 4 or the second heat dissipation protrusion 6 on the outermost side ranges from 16 to 32.
[0025] m rows of the first heat dissipation protrusion 4 and the second heat dissipation protrusion 6 The n columns can be arranged in square, rectangular, or parallelogram patterns.
[0026] The arrangement provided in the above embodiments is designed to protect against different arrangements of heat dissipation protrusions, including concentric circles, rectangles, squares, and parallelograms.
[0027] The first heat dissipation protrusion 4 and the second heat dissipation protrusion 6 have shapes including square grooves, round grooves and rhomboid grooves; the design of this embodiment is to protect the shape of the protrusions, including the form of square grooves, round grooves and rhomboid grooves.
[0028] The first heat dissipation protrusion 4 and the second heat dissipation protrusion 6 are made of materials including plastic and metal. This embodiment is designed to protect the materials of the protrusions, including both metal and plastic.
[0029] The row spacing of the first heat dissipation protrusions 4 is greater than the maximum distance between the two sides of the second heat dissipation protrusions. The second heat cover is nested outside the first heat dissipation cover 2. The second heat dissipation cover 3 can move up and down along the first heat dissipation cover 2 to completely cover the first heat dissipation protrusions 4 on the first heat dissipation cover 2, preventing dust from entering. This design is used when the computer does not need to be used for heat dissipation. Because the row spacing of the first heat dissipation protrusions 4 is greater than the maximum distance between the two sides of the second heat dissipation protrusions, the second heat dissipation cover 3 can move up or down along the first heat dissipation cover 2 to completely cover the first heat dissipation protrusions 4 with the baffles between the row spacing of the second heat dissipation protrusions 6, preventing dust from accumulating on the inner side of the first heat dissipation protrusions 4.
[0030] Unless otherwise specified, the equipment components involved in the above embodiments are all conventional equipment components, and the connection methods and control methods involved are all conventional connection methods and control methods unless otherwise specified.
[0031] The present invention has been described in detail above with reference to the embodiments. However, those skilled in the art will understand that, without departing from the spirit of the present invention, various specific parameters in the above embodiments can be changed to form multiple specific embodiments, all of which are common variations of the present invention, and will not be described in detail here.
