19” RACK MOUNT ENCLOSURES in 3U

The 3U sheet metal aluminum alloy chassis is a well-balanced and comprehensive solution, perfectly suited for high-value applications that demand a lightweight design, excellent thermal performance, and durability without sacrificing compatibility or reliability.

The core advantage of a 3U sheet metal aluminum alloy rackmount chassis is the synergy between its 3U form factor and aluminum alloy craftsmanship. This design tackles the key drawbacks of traditional steel enclosures—namely their weight, poor heat dissipation, and susceptibility to corrosion—without compromising on structural integrity or compatibility.

By leveraging a material that is significantly lighter than steel (30-50% less), the chassis reduces strain on racks, simplifies installation, and is ideal for weight-sensitive applications like wall-mounted or vehicle-mounted equipment. Its high thermal conductivity, which is 5-10 times better than steel, transforms the entire chassis into a passive heatsink, greatly improving cooling efficiency, especially in high-load scenarios like multi-drive servers.

Furthermore, the natural protective oxide film on aluminum provides superior corrosion and weather resistance, extending the lifespan of the equipment in harsh environments. The use of mature sheet metal processes ensures that despite being lightweight, the chassis remains structurally robust, able to withstand stacking and vibration.

In essence, the 3U sheet metal aluminum alloy chassis is a well-balanced solution for high-value applications that require lightweight design, excellent thermal performance, and durability without sacrificing compatibility or reliability.

Brushed and anodized finish

Application scope

data centers, enterprise IT, telecommunications, broadcast and professional AV, industrial control, security monitoring, and research/healthcare

Excellent Extrudability

6063-T5 aluminum is highly favored for its exceptional

This alloy forms a dense, natural oxide layer that provides outstanding corrosion resistance against atmospheric conditions, water, and many chemicals. This makes it a perfect choice for outdoor or high-moisture environments. The corrosion resistance can be further enhanced with anodizing, which also allows for a variety of colors and finishes.

Applications of Sheet Metal Enclosures

 

Sheet metal enclosures are primarily used to provide robust and durable protective casings for various electronic, mechanical, and electrical equipment. They play a critical role in numerous industries, including:

  • Electronics & Telecommunications: Used for casings of servers, networking devices, computers, and telecom base stations.

  • Industrial Automation: Serve as control cabinets and enclosures for industrial machinery and instruments, providing protection against harsh industrial environments.

  • Medical Devices: Offer enclosures that meet high standards for cleanliness and safety for diagnostic and monitoring equipment.

  • New Energy: Applied in devices like PV inverters, charging piles, and energy storage systems to withstand severe outdoor conditions.

  • Transportation & Security: Protect automotive electronics, railway signaling equipment, and security cameras.
