Bu en önemli işlevidir. It can effectively resist the invasion of outdoor wind, rain, dust, ice and snow, salt spray (coastal areas) and insects and ants, and prevent internal equipment from being damaged by moisture, dust accumulation or corrosion.
The sturdy box and reliable locks provide a physical barrier to prevent theft and damage for expensive built-in equipment, and can also prevent unauthorized personnel from misoperating.
Electronic equipment generates a lot of heat when running, and the outdoor ambient temperature varies greatly (the temperature inside the cabinet may be extremely high under the sun in summer and extremely low in winter). The outdoor cabinet maintains the temperature inside the cabinet within the range required for normal operation of the equipment through the built-in temperature control system (such as air conditioning, heat exchanger, fan, etc.), preventing the equipment from restarting or being damaged due to overheating or overcooling.
It integrates previously dispersed equipment (such as network equipment, transmission equipment, power supplies, batteries, etc.) into a unified, compact space and provides standardized mounting holes (such as 19-inch racks), making the equipment layout orderly and the cable management standardized, making maintenance and troubleshooting easier.
Genellikle IP65 veya IP55 koruma seviyesi benimsenir. IP65 means complete dustproof and can prevent low-pressure water spray from all directions, which means that even in strong winds and rainstorms, water and dust cannot enter the cabinet, and the reliability is extremely high.
The cabinet body is usually made of high-quality cold-rolled steel plate (with anti-rust treatment), stainless steel (such as 304/316) or glass fiber reinforced polyester (FRP). Bu malzemeler güçlü korozyon direncine, yaşlanma karşıtı ve ultraviyole direncine sahiptir ve uzun süreli rüzgar ve güneş ışığına dayanabilir.
Yaygın sıcaklık kontrol yöntemleri şunları içerir:
Endüstriyel klima: Güçlü soğutma kapasitesi, yüksek ısı üretimine sahip veya aşırı sıcak alanlar için uygundur.
Heat exchanger: heats away heat through internal and external circulation isolation, which can effectively prevent dust from entering and has a high energy efficiency ratio.
Fan filter: heats away heat through forced ventilation, which is low cost, but the filter needs to be replaced regularly to prevent dust accumulation.
Built-in lightning arresters, power distribution units (PDUs) and circuit breakers provide stable and safe power supply for the equipment and can effectively deal with the threat of outdoor lightning surges.
Before selecting, you must clarify the specific environment of the installation site (such as maximum/minimum temperature, rainfall, wind and sand conditions, whether it is coastal) and the number, size, total power consumption and heat generation of the equipment to be installed. Uygun koruma seviyesi, malzeme, boyut ve sıcaklık kontrol çözümünün seçilmesinin temeli budur.
Kabin güvenilir bir şekilde topraklanmalıdır. Good grounding is not only a requirement for the safe operation of the equipment, but also a key measure to prevent lightning strikes and ensure personnel safety.
Kablo girişini planlayın: Kablolar genellikle kabinin altından girer. Use waterproof connectors or cable glands to seal the cable entry to prevent water and insects from entering here and destroying the sealing of the entire cabinet.
During installation, sufficient space should be reserved around the ventilation openings of the cabinet (especially the heat exchanger and air conditioner fins) to avoid being close to the wall or piled with debris. Aksi takdirde ısı dağıtma etkisi ciddi şekilde etkilenecek ve sıcaklık kontrol sisteminin arızalanmasına neden olacaktır.
Yüksek kaliteli dolaplar bile düzenli bakım gerektirir. Buna aşağıdakiler dahildir: Sızdırmazlık şeritlerinin eskidiğini ve çatladığını kontrol etmek. Klima/ısı eşanjörü filtresinin ve ısı dağıtım kanatçıklarının temizlenmesi. Kilit ve menteşelerin esnek ve güvenilir olup olmadığının kontrol edilmesi. İçeride yoğuşma veya nem olup olmadığı kontrol ediliyor.
Biz esas olarak ağ dolabı, şarj arabası ve diğer altyapılar üretimiyle uğraşan bir şirketiz.
