Description

A high heat dissipation machine room cabinet

Technical Field

The invention relates to the technical field of cabinet heat dissipation, and in particular to a high heat dissipation machine room cabinet.

Background Art

The computer room cabinet, also known as the server cabinet, is used to combine installation panels, plug-ins, plug-in boxes, electronic components, devices and mechanical parts and components to form an integral installation box. The structure of the cabinet should have good rigidity and strength as well as good electromagnetic isolation, grounding, noise isolation, ventilation and heat dissipation properties. Efficient heat dissipation of the computer room cabinet can be achieved by ensuring that there is enough space around the cabinet, installing high-efficiency cooling fans inside the cabinet, and installing heat sinks or radiators on the equipment inside the cabinet, thereby ensuring the normal operation of the equipment and extending the service life of the equipment.

At present, high-heat dissipation computer room cabinets usually use the method of installing heat sinks or radiators to assist in heat dissipation. Heat sinks can increase the heat dissipation surface area and improve the heat dissipation efficiency. However, heat sinks are usually connected to the computer room cabinets by bolts, which is not convenient for quick installation and wastes time for installation. Secondly, after the heat sink is used for a long time, dust and impurities will stick to the surface, and it needs to be disassembled and cleaned to ensure that the surface is well ventilated. However, the disassembly and cleaning process is cumbersome and inconvenient to disassemble, and there is also the possibility of damaging other parts. Thirdly, cooling fans are usually installed inside the cabinet to promote air circulation and reduce the internal temperature of the equipment. However, the direction of the airflow driven by a single cooling fan has certain limitations, which can easily lead to poor local heat dissipation effect, and the airflow speed blown by the cooling fan remains unchanged, and the air flow efficiency is low.

Therefore, in order to facilitate the cleaning of the heat dissipation structure and improve the heat dissipation efficiency of the computer room cabinet, the present invention provides a high heat dissipation computer room cabinet.

Compared with the prior art, the present invention has the following advantages:

1. By arranging multiple heat sinks on the outer wall of the inner box of the cabinet, the surface area of the inner box of the cabinet in contact with the air is increased, which is convenient for accelerating heat dissipation. The quick installation component is then arranged to assist in the process of disassembling and assembling the heat sink.

At the same time, the second heat dissipation component is used to change the direction and speed of the wind flow, and the wind concentration channel changes the wind flow from dispersion to concentration. The wind flow alternates between the inner circle vents and the outer circle vents, which is convenient for changing the direction of the wind flow, reducing the wind flow blowing into dead corners, and more comprehensive heat dissipation, thereby achieving efficient heat dissipation of the computer room cabinet, ensuring the normal operation of the equipment and extending the service life of the equipment.

Through the cooperation of the first heat dissipation component 8 and the second heat dissipation component 9, the wind fanned out by the heat dissipation fan 89 enters the interior of the cabinet inner box 3 after passing through the concentrated air outlet channel 98. The concentrated air outlet channel 98 reduces the cross-sectional area of the air flow, so that the wind flow changes from dispersion to concentration, thereby accelerating the speed of the wind flow and the speed of taking away heat. The rotation of the inner ring baffle 96 and the outer ring baffle 97 causes the wind flow to circulate continuously from the inner ring to the outer ring and then from the outer ring to the inner ring, reducing the dead corners of the wind flow and preventing the occurrence of poor local heat dissipation efficiency.

The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
