What is the difference between the 2U chassis and the 4U chassis of the industrial control chassis and the server chassis? Today, Fanlong will come for you one by one!

1. Differences in parts in the chassis

The thickness of the 2U chassis is relatively small, while the 4U chassis is much thicker. Although the 2U chassis occupies a small amount of space, it has relatively high requirements for the power supply and the heat dissipation system of the chassis. The 4U chassis has a large space and many air holes, and the exhaust fans that can be installed are more random. The heat dissipation is much better than the relatively small 2U chassis. Too high temperature can easily affect the performance of the chassis. Therefore, the fan heat of the chassis is also an important reference condition when choosing industrial control chassis and server chassis. When you need to add more things to the case, only a 4U case can fit it.

2. The height difference of the chassis

Whether it is an industrial control chassis or a server chassis, they are all based on U, and U represents the height of the chassis. The standard height of 1U is 1.75 inches, which is 44.45 mm. There are usually 1U, 2U, 3U, 4U, 5U, 7U industrial control chassis and server chassis. The height of the 2U chassis and 4U chassis is 2U, which is 88.9 mm.

The size of the cabinets that house the industrial control cabinets and server cabinets also adopts this general industry standard. Usually 22U to 42U. The cabinet is also installed with a 1U height, detachable sliding bracket. Users can flexibly adjust the height according to the elevation of the industrial computer to store server chassis, industrial control chassis, and hub equipment.

3. the difference between appearance and hosting

Compared with the 4U chassis, the 2U chassis is much smaller and more attractive. At the same time, the 2U chassis occupies a relatively small space, so the cost of hosting is low, while the 4U chassis occupies a large space, so the hosting cost is higher. The tower type is more expensive, but its heat dissipation is good.

Therefore, when purchasing a 2U chassis and an industrial control chassis or a server chassis with a 4U chassis, you must comprehensively consider various factors and the additional costs that will be brought after the purchase. Choose the 2U or 4U chassis that suits you best.
