[0029] The following further describes the present utility model in detail with reference to the accompanying drawings:
[0030] See Figure 1 , the embodiments of the present utility model disclose a waterproof structure for the air outlet of a cabinet, including a cabinet. A waterproof louver 3 is arranged between the middle cabinet door 1 and the system fan 5 in the cabinet. The waterproof louver 3 is in the shape of a cross-shaped louver structure and is fixedly installed on a louver mounting member 6 inside the cabinet door 1; a waterproof film structure 4 is arranged between the waterproof louver 3 and the system fan 5. A drain groove is arranged at the bottom of the cabinet, and a drain hole is arranged in the drain groove. The louver angle of the waterproof louver is α, and the optimal waterproof angle under different water volumes can be simulated by adjusting the angle. The material is aluminum profile, and it is installed inside the cabinet mounting member through plastic parts on both sides. When the outdoor water volume is too large, the cross-shaped louvers cannot isolate the water source, and most of the water flows down along the outside of the louvers and flows out of the cabinet through the bottom drain hole. A small amount of water reaches the waterproof film structure 4 and is isolated through collision and sputtering. A sealing strip 2 is arranged on the contact surface between the cabinet door 1 and the cabinet body; a plurality of ventilation holes are arranged on the cabinet door 1, and the ventilation holes are strip-shaped holes or round holes. The density of the ventilation holes is determined according to the heat dissipation and ventilation requirements of the cabinet. The smaller the hole density, the more beneficial it is to improve the waterproof performance. On the basis of the traditional waterproof louver of the cabinet waterproof structure, a waterproof film structure is added to isolate the sputtered water mist that is easily overlooked at the air outlet outside the cabinet, which can effectively improve the reliability of the system fan in the cabinet and reduce the corrosion risk of the components in the cabinet. And the structure is light and convenient for installation, and can be added on the original structure to meet different requirements in different station environments.
[0031] See Figure 2, the waterproof membrane structure 4 includes a mounting frame 401, a screen 403 is installed in the mounting frame 401, and a waterproof and breathable membrane 401 is arranged on the screen 403. The screen 403 is made of stainless steel. The mesh number of the screen 403 is greater than or equal to 10 meshes, which is mainly used to support the waterproof membrane 401. The mounting frame 401 is fixedly connected to the cabinet louver mounting part 6 by spot welding or snap connection. The waterproof membrane structure includes a screen fixed in the mounting frame, and a waterproof and breathable membrane is supported on the screen. The waterproof and breathable membrane has a microscopic microporous structure, and the pore diameter is less than one ten-thousandth of the water droplet, which can effectively prevent water penetration and protect the internal equipment from moisture. And it has good air permeability. The micropore diameter is larger than the water vapor molecule, allowing air and water vapor to pass through smoothly, which helps with heat dissipation and prevents fogging. It also has good corrosion resistance, high temperature resistance and low temperature resistance, can resist the erosion of chemical substances, and protect the internal equipment and components from damage. It can maintain stable performance in high temperature and low temperature environments and will not deform or fail due to temperature changes. The waterproof and breathable membrane is soft and smooth, easy to install, and will not affect the appearance and use effect of the equipment. It can adapt to various climate conditions, including high temperature, low temperature, humidity, dryness and other environments. The microporous channel structure effectively blocks dust and protects the cleanliness inside the equipment. It has extremely strong chemical inertness and can resist ultraviolet radiation.
[0032] The working principle of the present utility model is as follows:
[0033] For the cabinet door of the present utility model, from the outside to the inside, there is a first level: openings are made on the cabinet door 1, which also has a certain waterproof function. The shape is formed by stamping strip holes or small round holes. The opening density here depends on the heat dissipation and ventilation requirements of the cabinet. The smaller the hole density, the more beneficial it is to improve the waterproof performance; the second level is provided with waterproof louvers 3. The louver angle α can simulate the best waterproof angle under different water volumes by adjusting the angle. The material is aluminum profile, and it is in a cross shape structure. It is installed in the cabinet louver mounting part 6 through plastic parts on both sides. When the outdoor water volume is too large, the cross-shaped louvers cannot isolate the water source. Most of the water flows down along the outside of the louvers and flows out of the cabinet through the bottom drain holes. A small amount of water enters the fan side of the internal system of the cabinet through collision and sputtering. Here, it reaches the design point of the present utility model: reaching the screen 403, with a mesh number of 10 meshes and above, mainly functioning to support the waterproof and breathable membrane 402. It has a porous structure, allows water vapor to seep out, reduces condensation, effectively waterproofs and repels oil, and can also reduce the generation of salt crystals to achieve waterproofing at the air outlet. This part of the component is installed and fixed behind the louver mounting part 6 by spot welding or snap connection, that is, in front of the system fan 5, which is the last step of the entire waterproofing. It effectively prevents the fan from being splashed by water mist and corroded by salt stains at the cabinet air outlet, achieving the effect of waterproofing at the cabinet air outlet.
[0034] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
