Outdoor communication cabinet is a chassis cabinet "> a kind of outdoor cabinet, which is directly exposed to the natural environment, such as those installed on the roadside, park, roof, mountain area and flat ground. Base station equipment, power supply equipment, storage battery, temperature control equipment, transmission equipment and other supporting equipment can be installed in the outdoor cabinet, or installation space and heat exchange capacity can be reserved for the above equipment, A cabinet that can provide reliable mechanical and environmental protection for the normal operation of internal equipment. Equipment providing outdoor physical working environment and safety system for wireless communication station or wired network station workstation. This cabinet cannot be operated by non professional personnel to prevent accidents or equipment damage.

戶外通信機(jī)柜的內(nèi)置設(shè)備很多，運(yùn)行時(shí)會(huì)產(chǎn)生大量的熱量，所以該種機(jī)柜的散熱性能必須很，才能保證各種設(shè)備的正常運(yùn)行。常用的散熱形式有兩種熱交換型和半導(dǎo)體型。

There are many built-in equipment in outdoor communication cabinet, which will generate a lot of heat during operation, so the heat dissipation performance of this kind of cabinet must be excellent to ensure the normal operation of various equipment. There are two common forms of heat dissipation: heat exchange type and semi conducting type.

熱交換型，采用熱交換器作為散熱設(shè)備的溫控元件，利用內(nèi)外完全隔離的風(fēng)道，通過(guò)相互隔絕的熱交換器芯傳遞熱量的散熱方式。熱交換器的選擇要根據(jù)戶外通信機(jī)柜內(nèi)部設(shè)備的發(fā)熱量來(lái)選擇。

The heat exchange type adopts the heat exchanger as the temperature control element of the heat dissipation equipment, and uses the completely isolated air duct inside and outside to transfer heat through the isolated heat exchanger core. The heat exchanger shall be selected according to the heating capacity of the equipment inside the outdoor communication cabinet.

半導(dǎo)體型，采用半導(dǎo)體設(shè)備對(duì)戶外機(jī)柜艙內(nèi)溫度進(jìn)行主動(dòng)制冷的一種方式，考慮室外惡劣條件應(yīng)用，半導(dǎo)體無(wú)壓縮機(jī)的制冷方式有利于提供制冷系統(tǒng)的可靠性。該類(lèi)恒溫戶外機(jī)柜在國(guó)內(nèi)聯(lián)通、移動(dòng)、電信運(yùn)營(yíng)商的集中采購(gòu)中應(yīng)用廣泛。

Semi conducting type is a way to actively cool the temperature in the outdoor cabinet cabin by using semiconductor equipment. Considering the application of outdoor harsh conditions, the refrigeration mode without semiconductor compressor is conducive to providing the reliability of the refrigeration system. This kind of thermostatic outdoor cabinet is widely used in the centralized procurement of domestic Unicom, China Mobile and telecom operators.
