Description

Technical Field

[0001] The utility model belongs to the technical field of display shells, and particularly relates to a display shell with multi-hole heat dissipation. Background Art

[0002] Computer monitors are one of the core output devices of modern computer systems, and their background technology covers multiple fields, including display technology, image processing, human-computer interaction, and hardware design. The electrical components in the monitor will generate heat after working, so it is necessary to open heat dissipation holes on the monitor casing to dissipate the heat generated by the electrical components.

[0003] For example, a Chinese patent with publication number CN216752557U discloses a high-efficiency heat dissipation device for a display, including a display housing and a screen, wherein the screen is fixedly connected to the front position of the display housing, a shell is fixed to the back of the display housing near the bottom, a heat dissipation hole A is provided on the back of the display housing, air inlet holes A are provided on both sides of the display housing parallel to the heat dissipation hole A, a heat conducting plate is fixed inside the display housing, the heat conducting plate is bonded to the back of the screen, ventilation holes are provided on the side and inside of the heat conducting plate, a connecting hole is provided on the back of the heat conducting plate at the position of the heat dissipation hole A, and the connecting hole and the ventilation hole are connected to each other.

[0004] The above-mentioned display casing is provided with heat dissipation holes A, heat dissipation holes B, heat dissipation fan A, and heat dissipation fan B, so that the internal heat is discharged to the outside of the casing, thereby achieving the effect of improving the heat dissipation efficiency. However, there are some defects in the multi-porous heat dissipation that need to be improved. In winter or when the ambient temperature is low, there is no need to use multi-porous heat dissipation holes. Since the heat dissipation holes at each position on the casing of the prior art are always open, too many heat dissipation holes will undoubtedly increase the probability of dust invading the inside of the display through the heat dissipation holes from the outside, causing potential damage to the internal precision circuit board. Therefore, a display casing is specially designed in which the number of heat dissipation holes opened can be adjusted according to the actual needs of the user and the usage scenarios.

[0030] Principle and advantages of use: When the ambient temperature is too low or only one heat dissipation position is needed, the second mesh plate 8 overlaps with the first mesh plate 7, and the shielding plate 9 shields one side of the groove 4. At this time, the number of heat dissipation positions can be reduced to prevent a large amount of dust from entering. When it is necessary to speed up the heat discharge in the display, the second mesh plate 8 is pushed by the handle 10, and the second mesh plate 8 drives the shielding plate 9 to slide into the installation frame 12. The block 132 is pushed and moves under the action of the spring 134. The guide block 135 slides in the guide groove 136, so that the block 132 moves stably without deviation. When the spring 134 makes the block 132 snap into the lower card hole 131, at this time, the second mesh plate 8 is located above the first mesh plate 7, and the porous positions are opened at the same time to facilitate heat dissipation of the display. When the second mesh plate 8 is located above the first mesh plate 7, the motor 61 is used to drive the screw rod 62 to rotate in the first slide groove 63, and one side of the frame of the exhaust fan 5 is threaded with the screw rod 62, and the other side of the frame of the exhaust fan 5 slides with the slide rod 65 in the second slide groove 64, so that the exhaust fan 5 can move up and down, which is convenient for heat to be discharged from the first mesh plate 7 and the second mesh plate 8 quickly, thereby improving the heat dissipation efficiency. At the same time, since the exhaust fan 5 blows outward, it can blow away dust in the air to prevent it from entering from the first mesh plate 7 and the second mesh plate 8.
