Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0026] Example 1, combined with Figure 1 and Figure 2 To explain:

[0027] A heat dissipation device for an LED display screen includes: an LED display screen 1, a display screen mounting frame 2, a heat dissipation plate 3, a partition frame 4, a micro refrigeration compressor 5, a refrigeration main pipe 6, a Venturi hot and cold mixing pipe 7, and a cover plate 8. The LED display screen 1 is fixedly mounted on the display screen mounting frame 2, and the display screen mounting frame 2 supports the LED display screen 1.

[0028] The heat dissipation plate 3 is arranged on the lower side of the LED display screen 1 , and is used to absorb and transfer the heat emitted by the LED display screen 1 .

[0029] The partition frame 4 is arranged at the lower side of the heat dissipation plate 3 , and the partition frame 4 divides the lower side area of ​​the heat dissipation plate 3 into multiple cooling zones, thereby ensuring uniform heat dissipation.

[0030] The micro refrigeration compressor 5 is fixedly installed under the heat sink 3. The refrigeration end of the micro refrigeration compressor 5 is connected to the venturi hot and cold mixing tube 7 through the refrigeration main pipe 6. There are multiple groups of venturi hot and cold mixing tubes 7. The multiple groups of venturi hot and cold mixing tubes 7 are arranged in parallel. The venturi hot and cold mixing tubes 7 are arranged in the refrigeration zone. The micro refrigeration compressor 5 provides cold air. The cold air enters the refrigeration zone through the refrigeration main pipe 6 and the venturi hot and cold mixing tube 7 and mixes with the hot air in the refrigeration zone, thereby achieving a cooling effect.

[0031] The cover plate 8 is arranged on the lower side of the partition frame 4 and is fixedly connected to the display screen mounting frame 2. The cover plate 8 is used to prevent the cold air from overflowing and provide a certain protection effect.

[0032] The micro refrigeration compressor 5 is a prior art and will not be described in detail here.

[0033] By setting up a micro refrigeration compressor 5, cold air can be quickly generated to cool the heat sink 3, thereby achieving the effect of cooling the LED display screen 1. By setting up a partition frame 4, the cold air can enter evenly, ensuring that all areas of the heat sink 3 can dissipate heat. By setting up a Venturi hot and cold mixing tube 7, the heat dissipation efficiency can be improved. By utilizing the Venturi principle, the mixing of cold air and hot air can be accelerated in advance, and the overall cooling efficiency can be increased by one half. By setting up a cover plate 8, dust can be prevented from entering the heat dissipation area and cold air can be prevented from overflowing.

[0034] Example 2, based on Example 1, combined with Figure 3 and Figure 4 To explain:

[0035] The Venturi hot and cold mixing tube 7 includes: a first thick tube 71, a thin tube 72, a second thick tube 73 and an adsorption tube 74. The first thick tube 71 and the second thick tube 73 are connected by the thin tube 72. One side of the thin tube 72 is connected to the adsorption tube 74. The first thick tube 71 is connected to the refrigeration end of the micro refrigeration compressor 5.

[0036] With this arrangement, when cold air passes through the capillary tube 72, the flow rate becomes faster, thereby lowering the air pressure in the adsorption tube 74, and then causing the adsorption tube 74 to generate suction, so that the hot air in the refrigeration area can be sucked into the capillary tube, thereby achieving a cooling effect.

[0037] Each refrigeration zone is provided with a group of Venturi hot and cold mixing pipes 7. Such arrangement ensures uniform heat dissipation.

[0038] There are two groups of adsorption tubes 74, which are arranged on both sides of the thin tube 72. This arrangement increases the adsorption area and improves the heat dissipation effect.

[0039] The refrigeration zones are arranged in a parallel and uniform array, which facilitates production installation and commissioning.

[0040] The micro-refrigeration compressor 5 is arranged on the upper side of the heat sink 3, and the output end port of the venturi hot and cold mixing pipe 7 is downward. In this way, the suction end of the micro-refrigeration compressor 5 can absorb the hot air rising to the top.

[0041] There are two groups of micro refrigeration compressors 5, which are symmetrically arranged on both sides of the upper end of the heat sink 3. This arrangement improves the heat dissipation effect.

[0042] It also includes a flow equalizing plate 9, which is arranged between the suction ends of the two groups of micro-refrigeration compressors 5. This arrangement allows the rising hot air to diffuse to both sides along the flow equalizing plate 9, thereby facilitating the micro-refrigeration compressor 5 to inhale.

[0043] The working principle of the present invention: When the present invention is in use, the heat dissipation plate transfers the heat generated by the LED display screen 1 to the refrigeration zone, and the micro-refrigeration compressor 5 starts to generate cold air. The cold air enters the Venturi hot and cold mixing tube 7 along the refrigeration main pipe 6. When the cold air passes through the thin tube 72, due to the Venturi effect, the adsorption tube 74 will generate adsorption force, and the hot air outside the thin tube 72 will be sucked into the thin tube 72, so that the hot air and the cold air are mixed, thereby achieving the purpose of cooling the middle of the refrigeration zone. Then the cold air is dissipated from the bottom of the second thick tube 73, thereby achieving the purpose of cooling the bottom of the refrigeration zone. Since the hot air has a small density and will move upward, the suction end of the micro-refrigeration compressor 5 will suck the hot air at the top of the refrigeration zone, thereby achieving the purpose of cooling the top of the refrigeration zone. One refrigeration cycle can cool the entire refrigeration zone, thereby improving the refrigeration efficiency. The present invention has a reasonable structure, can quickly dissipate heat from the LED display screen, and has a high heat dissipation efficiency.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, all changes that come within the meaning and range of equivalents of the claims are intended to be embraced by the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
