Description

Technical Field

[0001] The utility model relates to the technical field of chassis structures, in particular to an equipment chassis with a novel air inlet. Background Art

[0002] With the development of new energy technologies, the demand for related power supplies and energy storage products at home and abroad is constantly growing, and various new application scenarios have emerged: such as outdoor energy storage, mobile power products and household energy storage products. Most of the high-power products of this type of application inevitably use air-cooled cooling technology. Since the operating environment of these devices is worse than that of general electronic products, there are special design requirements on the air inlet of their casing.

[0003] When using metal materials for the housing, please refer to Figure 1 The existing technology is to punch holes of various shapes such as circles, rectangles, hexagons, etc. on the outer shell according to needs. The disadvantage of this type of shell design is that the inside of the product can be seen, and external debris can easily enter the interior of the product. In addition, due to process technology limitations, the size of a single hole in a chassis with high strength requirements cannot be made small enough to solve the problem of external debris entering the interior of the product. The commonly used solution is to add a shielding plate to the outer or inner surface of the chassis air inlet, but this undoubtedly increases the cost. The second is to adopt a design with a convex opening facing downward. Although this design can avoid the disadvantages of the first design and has a certain rainproof function, it has the disadvantage of no airflow in certain internal areas. For details, please refer to Figure 2 .

[0004] When using a plastic shell, the existing technology uses an inclined opening, such as a louver-like opening, or an inclined opening of other shapes. Their advantages are that the items inside the shell cannot be seen from the front and at a certain angle from top to bottom, which has a certain aesthetic appeal. At the same time, it can avoid the risk of most external debris falling directly into the interior and damaging the product. However, it also has the following disadvantages: First, the airflow also has an inclined angle with the shape of the opening, which will cause some areas inside the product to have no airflow passing through. If there are components that need to be cooled in this area, it will increase the difficulty of design. Second, the cost is higher than that of metal shells.

[0005] Therefore, it is urgent to provide a device chassis with a new air inlet to overcome the above-mentioned defects. Utility Model Content

[0006] The main purpose of the utility model is to provide an equipment chassis with a novel air inlet, which solves the problem of impurities easily entering the chassis and overcomes the defect of no cold air flow in specific areas of the product, and has the advantage of relatively low production cost.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] An equipment chassis with a new type of air inlet, comprising: a chassis main body with a wind wheel mechanism installed on one side, further comprising: a plurality of air inlet structures recessed and formed on a panel of the chassis main body opposite to the side where the wind wheel mechanism is installed;

[0009] Each of the air inlet structures includes: an air inlet hole formed on the panel, and a protruding baffle obliquely protruding on a surface of the panel facing the wind wheel mechanism, which acts with the air inlet hole to guide the air inlet duct to have an arc-shaped trend.

[0010] Preferably, the protruding baffle is in a U shape, and the protruding baffle faces the air inlet hole, and both sides of the protruding baffle and the air inlet hole respectively form an air inlet duct.

[0011] Preferably, each of the air inlet structures is in a rectangular body shape and regularly protrudes on a surface of the panel facing the wind wheel mechanism, and the air inlets are located on two side surfaces adjacent to the air inlet hole.

[0012] Preferably, the height values of the protruding baffle protruding from the panel are not equal.

[0013] Preferably, the height values of the protruding baffle protruding from the panel are equal.

[0014] Preferably, the protruding baffle includes: a first baffle, and second baffles arranged at both ends of the first baffle and enclosing an air inlet with the first baffle, and the air inlet is adjacent to the air inlet hole.

[0015] Preferably, the first baffle is in a shape of a reverse L, and the air inlet faces the inclined surface of the first baffle.

[0016] The beneficial effects of the present utility model are as follows: a plurality of the air inlet structures are recessed and formed on a panel opposite to the side where the wind wheel mechanism is installed, and each of the air inlet structures is designed as a non-linear air inlet duct design that guides the air inlet duct to have an arc-shaped trend, which overcomes the defect that dust and impurities are easily introduced in the prior art, and avoids the effect of the internal environment being visible. In addition, the design method of recessing and forming the air inlet structure also overcomes the defect that there is no air flow in a specific area in the air inlet structure design in the prior art. In addition, the design of this structure effectively reduces the production cost. Description of the Drawings

[0035] In a preferred embodiment, the chassis body 1 is square, and the wind wheel mechanism 2 and the plurality of air inlet structures 3 are respectively arranged on two opposite panels of the chassis body 1. Specifically, the wind wheel mechanism 2 can be a fan.

[0036] In a preferred embodiment, each of the air inlet structures 3 includes: an air inlet hole a1 formed on the panel, a protruding baffle a2 obliquely protruded on a surface of the panel facing the wind wheel mechanism 2, and acting with the air inlet hole a1 to guide the air inlet duct in an arc shape, the protruding baffle a2 is in a U-shape, and the protruding baffle a2 is directly opposite to the air inlet hole a1, and the two sides of the protruding baffle a2 and the air inlet hole a1 respectively form an air inlet duct, each of the air inlet structures 3 is in a rectangular shape and regularly protruded on a surface of the panel facing the wind wheel mechanism 2, and the air inlets are located on the two side surfaces adjacent to the air inlet, and the height value of each protruding baffle a2 protruding from the panel is equal, and its working effect can be seen in FIG.
