Abstract
Description
Technical Field
[0001] This utility model relates to the field of display heat dissipation technology, specifically to a high-efficiency heat dissipation structure for displays. Background Technology
[0002] Monitor heat dissipation refers to the process of temperature control of a monitor to ensure that it can remain within a safe operating temperature range during long-term use. When a monitor is working, its internal electronic components, such as the LCD screen, backlight tubes, and circuit boards, generate heat. If this heat cannot be effectively dissipated, it will cause the monitor to overheat, which may lead to reduced performance, shortened lifespan, or even hardware damage.
[0003] Common heat dissipation methods for monitors mainly rely on air cooling. In this case, a fan needs to be installed inside the monitor. However, as monitors are made thinner and thinner, the space inside for device installation is limited. This results in smaller and fewer fans being needed, which often cannot meet the actual needs. Therefore, an external, high-efficiency heat dissipation structure needs to be designed to cool the monitor. Utility Model Content
[0004] The purpose of this invention is to provide a high-efficiency heat dissipation structure for displays, so as to solve the problems mentioned in the background art.

The display screen is fixed to the front end of the outer frame. An air inlet is provided on the upper rear side of the outer frame, and an air outlet is provided on the lower rear side of the outer frame. A connecting column is fixed at the air outlet. The bottom of the connecting column is fixed to the counterweight base. A through hole is provided in the connecting column at a position corresponding to the air outlet. The bottom of the through hole extends to the rear side of the counterweight base and a cooling fan is fixed thereon.
[0006] Preferably, a pair of fixed legs are fixed to the rear side of the lower end of the counterweight base, a telescopic support plate is installed on the front side of the lower end of the counterweight base, and a telescopic component is provided inside the counterweight base at a position corresponding to the telescopic support plate.
[0007] Preferably, the telescopic assembly includes a threaded rod and a telescopic groove. The telescopic groove is formed on the upper end of the counterweight base and is aligned with the telescopic support plate. The upper end of the telescopic support plate is slidably connected to the telescopic groove. The threaded rod is rotatably connected to the telescopic groove. The bottom of the threaded rod is threadedly connected to the telescopic support plate. The upper end of the threaded rod extends out of the upper end of the counterweight base and is fixed with a knob.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-4 This utility model provides a technical solution: including an outer frame 1, a display screen 2, and a counterweight base 4. The display screen 2 is fixed to the front end of the outer frame 1. An air inlet 13 is provided on the upper rear side of the outer frame 1, and an air outlet 14 is provided on the lower rear side of the outer frame 1. A connecting column 3 is fixed at the air outlet 14. The bottom of the connecting column 3 is fixed to the counterweight base 4. A through hole 31 is provided in the connecting column 3 at a position corresponding to the air outlet 14. The bottom of the through hole 31 extends to the rear side of the counterweight base 4 and a cooling fan 32 is fixed thereon. A heat-conducting plate 11 is installed and fixed on the back of the display screen 2. A heat sink 12 is fixed on the heat-conducting plate 11. An opening slot 48 is provided on the rear side of the counterweight base 4 at a position corresponding to the cooling fan 32. Dustproof plates 5 are fixed in both the opening slot 48 and the air inlet 13. A temperature sensor is fixed inside the outer frame 1.
[0019] A pair of fixed feet 41 are fixed to the rear side of the lower end of the counterweight base 4. A telescopic support plate 42 is installed on the front side of the lower end of the counterweight base 4. A telescopic component is provided inside the counterweight base 4 and at a position corresponding to the telescopic support plate 42. The telescopic component includes a threaded rod 44 and a telescopic groove 43. The telescopic groove 43 is opened at the upper end of the counterweight base 4 and is aligned with the telescopic support plate 42. The upper end of the telescopic support plate 42 is slidably connected to the telescopic groove 43. The threaded rod 44 is rotatably connected to the telescopic groove 43. The bottom of the threaded rod 44 is threadedly connected to the telescopic support plate 42. The upper end of the threaded rod 44 extends out of the upper end of the counterweight base 4 and is fixed with a knob 45. A limit block 46 is fixed on the outer side of the telescopic support plate 42 and inside the counterweight base 4. A limit groove 47 is opened on the side wall of the telescopic groove 43 at a position corresponding to the limit block 46. The limit block 46 is slidably connected to the limit groove 47.
[0020] Working principle: First, connect the entire device to an external power source. Driven by the cooling fan 32, the gas inside the outer frame 1 can be discharged through the perforation 31, and air can be drawn in through the air inlet 13, creating a stable gas flow inside the outer frame 1. Under these conditions, the heat-conducting plate 11 absorbs the heat generated by the display screen 2 and transfers it to the heat sink 12, until the air inside the outer frame 1 is heated. Through the above air circulation, the hot air inside the outer frame 1 can be discharged. Since the cooling fan 32 is not installed inside the outer casing, a larger power or more cooling fans 32 can be added according to the specifications of the display. To save on the problem of the display screen 2 not being able to adjust its tilt angle due to the fixed connection at both ends of the connecting column 3, the telescopic support plate 42 can be extended and retracted to change the support height of the front end of the counterweight base 4, thereby achieving overall support tilt angle adjustment. During operation, simply turn the knob 45, which will drive the threaded rod 44 to rotate, which will drive the telescopic support plate 42 to extend and retract. The operation is simple and convenient.
