Description

Technical Field

[0001] The utility model relates to the technical field of cabinet panels, in particular to a cabinet mesh panel with a high ventilation rate and a cabinet. Background Art

[0002] In data centers, communication base stations and other fields, cabinets, as important carriers of equipment, need to maintain good ventilation performance to ensure the normal operation and heat dissipation of internal equipment.

[0003] In order to achieve the ventilation performance of the cabinet, people generally set a plurality of ventilation holes on the cabinet plate. For example, Chinese patent document CN2012206335486 discloses a mesh plate for a network cabinet, which includes a mesh plate body, and the mesh plate body is evenly provided with a plurality of heat dissipation mesh holes, and the heat dissipation mesh holes are regular hexagons. It can be seen that the above cabinet plate improves the ventilation efficiency through the mesh design, but how to further improve the ventilation rate of the cabinet mesh has become a problem to be solved. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a cabinet mesh plate with a high ventilation rate, including a cabinet mesh plate body, on which heat dissipation mesh holes are evenly arranged and staggered, and the heat dissipation mesh holes include regular hexagonal holes and expansion holes outside the regular hexagonal holes. By arranging the expansion hole structure outside the regular hexagonal holes, the ventilation area of ​​each heat dissipation mesh hole is expanded without changing the arrangement of the regular hexagonal holes, that is, the overall ventilation area of ​​the cabinet mesh plate body is enlarged, thereby improving the ventilation rate.

[0005] In one embodiment, the expansion holes are holes outside the six corners of the regular hexagonal hole. By expanding the hexagonal hole outside the six corners of the regular hexagonal hole, the strength reduction between the heat dissipation mesh holes caused by the expansion holes is avoided, thereby ensuring the overall strength of the cabinet mesh plate body.

[0006] In one embodiment, the molded hole is formed by extending and intersecting half of two adjacent sides of a regular hexagonal hole.

[0007] In one embodiment, the angle of expansion of half of the two adjacent sides of the regular hexagonal hole is 0.3-0.6 degrees. Specifically, by fine-tuning the side of the regular hexagonal hole, the ventilation area of ​​each heat dissipation mesh hole is expanded without affecting the strength of the cabinet mesh plate body.

[0008] In one embodiment, the positions where the two adjacent sides of the regular hexagonal hole are extended and intersected are rounded. By setting the rounded corners, the mold and the tool can be better set, so that each connection is a smooth transition, the processing difficulty of the mold and the tool caused by the straight corner is reduced, and the service life of the mold and the tool can be increased.

[0009] The utility model also discloses a cabinet, which is composed of the cabinet mesh plate with high ventilation rate. The cabinet is prepared by using the cabinet mesh plate with high ventilation rate, thereby improving the ventilation rate of the cabinet as a whole. BRIEF DESCRIPTION OF THE DRAWINGS

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] Example 1

[0022] like Figure 1-4 As shown, the present embodiment discloses a cabinet mesh plate with a high ventilation rate, which includes a cabinet mesh plate body 1, and the cabinet mesh plate body 1 is evenly arranged with staggered heat dissipation mesh holes 2, and each of the heat dissipation mesh holes includes a regular hexagonal hole 3 and an expansion hole outside the regular hexagonal hole 3. Preferably, the expansion hole is a type hole 4 outside the regular hexagonal hole 3. Specifically, the type hole 4 is formed by the half of the adjacent two sides of the regular hexagonal hole 3 extending outwards and intersecting and enclosing. As for the angle of the outward expansion, it is between 0.3-0.6 degrees, preferably 0.475 degrees. At this time, one side of the regular hexagonal hole takes the center as a corner, and the angle A formed is 179.05 degrees. Furthermore, the position where the half of the adjacent two sides of the regular hexagonal hole 3 extend outwards and intersect is rounded, and the preferred fillet radius R is 0.2mm.

[0023] Alternatively, the molded hole 4 is an arrow hole formed outside the six corners of the regular hexagonal hole 3, and the head position of the arrow is chamfered.

[0024] Take the regular hexagonal hole with an inscribed circle diameter of 8 mm as an example to illustrate the expansion of ventilation area. Figure 5 As shown, in the prior art, the heat dissipation mesh hole is a regular hexagon, the inscribed circle diameter is 8 mm, and the ventilation area of ​​each heat dissipation mesh hole is 55.43 mm 2 , and in this application, if Figure 1 As shown, it is Figure 5 For reference processing, the inscribed circle of the heat dissipation mesh is 8mm. At this time, the ventilation area of ​​each heat dissipation mesh is 56.25mm 2 ,It can be seen that the heat dissipation and ventilation area of ​​the present application is larger than the hexagonal mesh of the prior art.

[0025] As for the processing and production, it is processed through a punching machine and subsequently processed through shearing machines, rolling machines and other settings.

[0026] Example 2

It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
