服務(wù)器機(jī)柜，用來(lái)組合安裝面板、插件、插箱、電子元件、器件和機(jī)械零件與部件，使其構(gòu)成一個(gè)整體的安裝箱。服務(wù)器機(jī)柜由框架和蓋板（門(mén)）組成，一般具有長(zhǎng)方體的外形，落地放置。它為電子設(shè)備正常工作提供相適應(yīng)的環(huán)境和安全防護(hù)。這是僅次于系統(tǒng)級(jí)的一級(jí)組裝。不具備封閉結(jié)構(gòu)的機(jī)柜稱為機(jī)架。服務(wù)器機(jī)柜具有良好的技術(shù)性能。機(jī)柜的結(jié)構(gòu)應(yīng)具有良好的剛度和強(qiáng)度以及良好的電磁隔離、接地、噪聲隔離、通風(fēng)散熱等性能。此外，服務(wù)器機(jī)柜應(yīng)具有抗振動(dòng)、抗沖擊、耐腐蝕、防塵、防水、防輻射等性能，以便保證設(shè)備穩(wěn)定可靠地工作。
機(jī)柜原本是美國(guó)軍方電子控制儀器的一種規(guī)格,其設(shè)定的目的在于統(tǒng)一儀器的外形尺寸和方便快速組裝抽換和維護(hù),最后隨著軍方技術(shù)轉(zhuǎn)移民間,此規(guī)格亦廣泛的被企業(yè)界所采用。
機(jī)柜的優(yōu)點(diǎn)在于提供機(jī)箱安全保護(hù)和擴(kuò)充的便利性,早期常用于工業(yè)控制機(jī)臺(tái),近幾年由于網(wǎng)絡(luò)的發(fā)展,網(wǎng)絡(luò)通訊設(shè)備也開(kāi)始大量使用;因此其產(chǎn)品的種類大致可區(qū)分成辦公室用和工業(yè)用產(chǎn)品兩大類。

Server cabinets are used to combine installation panels, plug-ins, boxes, electronic components, devices, and mechanical parts and components to form a whole box. The server cabinet consists of a frame and a cover plate(door), which generally has the shape of a cuboid and is placed on the ground. It provides suitable environment and safety protection for the normal operation of electronic equipment. This is a primary assembly second only to the system level. A cabinet that does not have a closed structure is called a rack. Server cabinet has good technical performance. The structure of the cabinet should have good stiffness and strength as well as good electromagnetic isolation, grounding, noise isolation, ventilation and heat dissipation. In addition, the server cabinet should have anti-vibration, anti-impact, anti-corrosion, anti-dust, waterproof, anti-radiation and other properties in order to ensure the stable and reliable operation of the equipment.
The cabinet was originally a specification of the electronic control instrument of the United States military. Its purpose was to unify the size of the instrument and facilitate the rapid assembly and replacement and maintenance. Finally, with the transfer of military technology, this specification was also widely adopted by the business community..
The advantage of the cabinet is that it provides the convenience of security protection and expansion of the chassis. It was often used in industrial control machines in the early days. In recent years, due to the development of the network, network communication equipment has also begun to be used extensively; Therefore, the types of products can be roughly divided into two categories: office and industrial products.
