戶外通信機(jī)柜是機(jī)箱機(jī)柜">戶外機(jī)箱機(jī)柜的一種,它直接暴露在自然環(huán)境中,如公路邊、公園、樓頂、山區(qū)、平地安裝的機(jī)柜,戶外機(jī)箱機(jī)柜內(nèi)可安裝基站設(shè)備、電源設(shè)備、蓄電池、溫控設(shè)備、傳輸設(shè)備及其他配套設(shè)備或?yàn)橐陨显O(shè)備預(yù)留安裝空間及換熱容量,能為內(nèi)部設(shè)備正常運(yùn)行提供可靠的機(jī)械和環(huán)境保護(hù)的機(jī)柜。為無線通信站點(diǎn)或有線網(wǎng)絡(luò)站點(diǎn)工作站提供戶外物理工作環(huán)境和系統(tǒng)的設(shè)備。這種機(jī)柜非權(quán)限人員是不能操作的以防發(fā)生意外或設(shè)備損毀的事故。
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。該類恒溫戶外機(jī)柜在國內(nèi)聯(lián)通、移動(dòng)、電信運(yùn)營(yíng)商的集中采購中應(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.
