濟(jì)南機(jī)箱機(jī)柜作為各類電子設(shè)備、儀器的承載裝置，其散熱性能直接影響內(nèi)部設(shè)備的穩(wěn)定運(yùn)行。在濟(jì)南的工業(yè)環(huán)境與機(jī)房場(chǎng)景中，機(jī)箱機(jī)柜需應(yīng)對(duì)設(shè)備長時(shí)間運(yùn)行產(chǎn)生的熱量積聚，通過科學(xué)的設(shè)計(jì)與配置，構(gòu)建多維度的散熱體系。

　　As a load-bearing device for various electronic equipment and instruments, the heat dissipation performance of Jinan chassis cabinets directly affects the stable operation of internal equipment. In the industrial environment and computer room scenarios of Jinan, chassis cabinets need to deal with the heat accumulation generated by long-term operation of equipment. Through scientific design and configuration, a multi-dimensional heat dissipation system is constructed.

　　結(jié)構(gòu)設(shè)計(jì)是散熱的基礎(chǔ)保障。濟(jì)南機(jī)箱機(jī)柜多采用鏤空通風(fēng)結(jié)構(gòu)，在柜體頂部、底部及側(cè)面設(shè)置密集的散熱孔，形成自然對(duì)流

　　Structural design is the fundamental guarantee for heat dissipation. Jinan computer cabinets often adopt hollow ventilation structures, with dense heat dissipation holes set at the top, bottom, and sides of the cabinet to form natural convection

　　通道，熱空氣通過頂部出風(fēng)口排出，冷空氣從底部或側(cè)面進(jìn)風(fēng)口補(bǔ)充，利用空氣密度差實(shí)現(xiàn)基礎(chǔ)散熱。部分機(jī)柜采用分層式內(nèi)部架構(gòu)，將發(fā)熱量大的設(shè)備與散熱需求低的設(shè)備分區(qū)放置，減少熱量相互干擾；柜體內(nèi)部預(yù)留充足的走線空間，避免線纜纏繞阻礙空氣流通，確保散熱通道暢通，就像濟(jì)南老巷中的通風(fēng)設(shè)計(jì)，通過合理布局讓空氣自然流動(dòng)。

　　Channel, hot air is discharged through the top air outlet, and cold air is replenished through the bottom or side air inlet, utilizing the difference in air density to achieve basic heat dissipation. Some cabinets adopt a layered internal architecture, placing devices with high heat generation and devices with low heat dissipation requirements in separate zones to reduce heat interference with each other; Adequate wiring space is reserved inside the cabinet to avoid cable entanglement obstructing air circulation and ensure smooth heat dissipation channels, just like the ventilation design in Jinan's old alleys, which allows natural air flow through reasonable layout.

　　主動(dòng)散熱組件的配置增強(qiáng)了散熱效率。針對(duì)高功率設(shè)備的機(jī)柜，會(huì)安裝軸流風(fēng)扇或離心風(fēng)扇，風(fēng)扇通常分布在機(jī)柜頂部或背部，通過強(qiáng)制排風(fēng)加快內(nèi)部熱空氣與外部冷空氣的交換速度。部分機(jī)柜配備溫控風(fēng)扇系統(tǒng)，當(dāng)內(nèi)部溫度達(dá)到設(shè)定閾值時(shí)，風(fēng)扇自動(dòng)啟動(dòng)并調(diào)節(jié)轉(zhuǎn)速，溫度降低后自動(dòng)停止，既保證散熱效果，又避免能源浪費(fèi)。在濟(jì)南夏季高溫環(huán)境下，這種主動(dòng)散熱方式能有效應(yīng)對(duì)設(shè)備集中產(chǎn)生的大量熱量，防止因溫度過高導(dǎo)致停機(jī)。

　　The configuration of active heat dissipation components enhances heat dissipation efficiency. For high-power equipment cabinets, axial flow fans or centrifugal fans are installed, which are usually distributed on the top or back of the cabinet to accelerate the exchange speed between internal hot air and external cold air through forced exhaust. Some cabinets are equipped with temperature controlled fan systems. When the internal temperature reaches the set threshold, the fan automatically starts and adjusts the speed. When the temperature drops, it automatically stops, ensuring heat dissipation and avoiding energy waste. In the high temperature environment of Jinan in summer, this active heat dissipation method can effectively cope with the large amount of heat generated by equipment concentration and prevent shutdown due to high temperature.

　　材質(zhì)選擇對(duì)散熱性能有重要影響。濟(jì)南機(jī)箱機(jī)柜多選用導(dǎo)熱性良好的合金材料，如冷軋鋼板，通過柜體自身的熱傳導(dǎo)將內(nèi)部熱量散發(fā)到外部環(huán)境。部分機(jī)柜表面采用鍍鋅或噴塑處理，不僅增強(qiáng)防腐能力，還能通過涂層的輻射散熱作用輔助降溫。對(duì)于特殊場(chǎng)景的機(jī)柜，會(huì)在內(nèi)部加裝導(dǎo)熱墊片或散熱鰭片，將設(shè)備產(chǎn)生的熱量快速傳導(dǎo)柜體，再通過柜體與外界的接觸面積擴(kuò)大散熱范圍，提升整體散熱效率。

　　The selection of materials has a significant impact on heat dissipation performance. Jinan computer cabinets often use alloy materials with good thermal conductivity, such as high-quality cold-rolled steel plates, to dissipate internal heat to the external environment through the heat conduction of the cabinet itself. Part of the cabinet surfaces are treated with galvanizing or spray coating, which not only enhances the anti-corrosion ability, but also assists in cooling through the radiation heat dissipation effect of the coating. For cabinets in special scenarios, thermal pads or heat dissipation fins will be installed inside to quickly transfer the heat generated by the equipment to the cabinet, and then expand the heat dissipation range through the contact area between the cabinet and the outside world, improving the overall heat dissipation efficiency.

　　環(huán)境適配設(shè)計(jì)進(jìn)一步強(qiáng)化散熱效果。在濟(jì)南潮濕或多塵的環(huán)境中，機(jī)柜的散熱系統(tǒng)會(huì)搭配防塵網(wǎng)和防潮裝置，在保證通風(fēng)的同時(shí)，防止灰塵堵塞散熱孔或濕氣影響設(shè)備。部分戶外機(jī)柜采用防雨防曬結(jié)構(gòu)，頂部設(shè)計(jì)傾斜角度的防雨檐，側(cè)面通風(fēng)口加裝百葉窗式防護(hù)罩，既避免雨水進(jìn)入，又不影響空氣流通，確保在濟(jì)南復(fù)雜的戶外環(huán)境中仍能穩(wěn)定散熱。此外，機(jī)柜的安裝位置也會(huì)考慮環(huán)境因素，如避開陽光直射區(qū)域、靠近通風(fēng)良好的空間，與散熱設(shè)計(jì)形成協(xié)同作用。

　　Environmental adaptation design further enhances the heat dissipation effect. In the humid or dusty environment of Jinan, the cooling system of the cabinet will be equipped with dust-proof nets and moisture-proof devices to ensure ventilation while preventing dust from blocking the cooling holes or moisture from affecting the equipment. Some outdoor cabinets adopt a rainproof and sun proof structure, with a sloping rainproof eave on the top and louvered protective covers installed on the side ventilation openings to prevent rainwater from entering and not affect air circulation, ensuring stable heat dissipation in the complex outdoor environment of Jinan. In addition, the installation location of the cabinet will also consider environmental factors, such as avoiding areas with direct sunlight, being close to well ventilated spaces, and forming a synergistic effect with heat dissipation design.
