Outdoor rack ventilation heat abstractor

Technical Field

The invention relates to the technical field of outdoor cabinets, in particular to a ventilating and heat-dissipating device of an outdoor cabinet.

Background

An outdoor communication cabinet is a device for providing outdoor working environment and safety guarantee for wired or wireless communication equipment. Due to the wide range of outdoor communication equipment use, such equipment can be deployed quite often in harsher natural environments. Early communication devices were typically configured with a dedicated room. With the popularization of mobile communication, the number of outdoor communication equipment is increased rapidly, and a substitute for a civil engineering machine room, namely an outdoor cabinet, is provided for reducing cost. Communication equipment, power supply equipment, storage batteries, temperature control equipment, transmission equipment and other accessory equipment can be installed in the outdoor cabinets. Because the communication equipment works continuously for 7-24 hours, a large amount of heat is accumulated in the cabinet, so that the temperature in the cabinet rises sharply. When the temperature exceeds the upper limit of the working temperature of the communication equipment, certain components such as chips in the communication equipment can be permanently damaged or temporarily failed, so that the communication equipment can not work normally. Therefore, how to transfer heat in the cabinet becomes one of the key issues for reliable and continuous operation of the communication equipment.

Common heat dissipation methods include natural heat dissipation and active heat dissipation. Active heat dissipation methods include fan heat dissipation, industrial air conditioning and the like. The importance, the heat productivity and the heat dissipation cost of the communication equipment are comprehensively considered, and a fan heat dissipation mode with higher cost performance can be selected by a plurality of users. The fan radiating mode is that environment fresh air with relatively low external temperature is led into the cabinet through the fan, the working heat of the communication equipment is taken away by driving cold air, and hot air is discharged out of the cabinet, so that the purpose of reducing the internal temperature of the cabinet is achieved. Obviously, the air duct is an important channel for taking away heat, so a reasonable and smooth air duct is needed to be arranged in a fan heat dissipation mode, the wind resistance is smaller, and the heat dissipation efficiency is higher. Secondly, the fan is the heart of the whole heat dissipation system, when the fan breaks down, the maintainability is good, and the fan must be replaced quickly and conveniently in time.

Because the outdoor communication rack sets up in the open air, in comparatively abominable stormy weather, the rainwater receives wind-force to influence, will hit with certain contained angle of deviating from the plumb line and hit on outdoor rack and mounting platform, the condition of some drop splashes into the shutter can appear in some occasions, causes following problem: on the one hand drop of water gets into the easy potential safety hazard that forms in cabinet, and on the other hand is close to the dust screen of shutter and is stained with the water back, and dust, fibre etc. on the dust screen can combine with water to form the mud, block up the dust screen, both can cause the wind channel windage to rise, reduce the radiating efficiency, also can cause the change of dust screen or cleaning frequency to rise, have increaseed fortune dimension cost.

In addition, the lifting rings of many traditional cabinets are exposed outside, so that the lifting rings are not protected in rainy days, and connecting threads are easily corroded and rusted by rainwater.
