Outdoor cabinet with air channel structure

Abstract

The invention relates to an outdoor cabinet with an air channel structure, which comprises a cabinet body, and a fan mechanism and a top cover which are arranged on the cabinet body, wherein the cabinet body comprises a front door, a rear cover and two side walls; the front door and the rear cover are provided with a first air inlet and a second air inlet respectively; the inner side of the frontdoor and the inner side of the rear cover are provided with a front inner plate and a rear inner plate respectively; the front inner plate and the front door form a first air channel; a second air channel is formed between the rear inner plate and the rear cover; the lower end of the front inner plate is slantwise provided with a first fan mechanism; the lower end of the rear inner plate is slantwise provided with a second fan mechanism; the top cover is arranged on the upper end face of a top plate of the cabinet body, and a third air channel is formed between the top cover and the top plate; and the top plate is provided with a third fan mechanism. Compared with the prior art, the outdoor cabinet has the advantages that cold air outside the cabinet body is fully contacted with heat in the cabinet body, so the outdoor cabinet is smooth in ventilation and rapid in temperature reduction, reduces energy consumption and reduces noise.

Description

technical field [0001] The invention relates to an outdoor cabinet applied in the communication field, in particular to an outdoor cabinet with an air duct structure. Background technique [0002] As a substitute for computer room stations, outdoor cabinets are becoming more and more popular in the market. The existing outdoor cabinets generally include a cabinet body with a top plate on the top and a bottom plate on the bottom. There is no cooling equipment such as fans. Usually, there are Switches and other heat-prone equipment use the natural circulation system to cool down. During operation, the temperature of the heating layer can even be 35°C higher than the outside temperature. The heat generated by the power supply and other equipment cannot be quickly discharged to the outside. As a result, the operation stability of the functional modules in the cabinet is reduced, and the service life of the components is shortened. [0003] In order to improve the cooling effect...

[0002] As a substitute for computer room stations, outdoor cabinets are becoming more and more popular in the market. The existing outdoor cabinets generally include a cabinet body with a top plate on the top and a bottom plate on the bottom. There is no cooling equipment such as fans. Usually, there are Switches and other heat-prone equipment use the natural circulation system to cool down. During operation, the temperature of the heating layer can even be 35°C higher than the outside temperature. The heat generated by the power supply and other equipment cannot be quickly discharged to the outside, resulting in a decrease in the operational stability of the functional modules in the cabinet and a shortened service life of the components

[0003] In order to improve the cooling effect, it is realized by adding an air conditioner. Although this method has a better effect, the air conditioner occupies a large volume, and there are still disadvantages such as high cost, high energy consumption, and serious noise pollution.

[0004] In order to reduce costs and reduce installation space, outdoor cabinets generally use exhaust fans to exhaust air to achieve one-way circulation to cool down. Usually, exhaust fans are installed on the top of the cabinet to suck the hot air in the cabinet to the outside. , such as the Chinese utility model patent "Forced Ventilation Device for Outdoor Cabinets" (authorized announcement number: CN2831715Y) with the patent number ZL200520077074.1, and the Chinese utility model patent "Intelligent Outdoor Communication Cabinet" with the patent number ZL200720108881.4 ( Authorized announcement number: CN201063988Y), however, the general cabinet is relatively high, and the exhaust fan can only extract the hot air generated in the upper part of the cabinet, but cannot easily complete the suction for the hot air in the lower part of the cabinet, so for the modules in the lower part of the cabinet Or the hardware is not ideal for heat dissipation

In addition, due to the unreasonable layout of the fan mechanism, the air outlet of the fan produces a large wind resistance, which makes the exhaust air not smooth and affects the heat exchange efficiency of the cabinet.
