What is the difference between the 2U chassis and the 4U chassis of the industrial control chassis and the server chassis?

1. The height difference of the chassis

Whether it is an industrial control chassis or a server chassis, they are all based on U as the enterprise, and U means the chassis is highly standardized. The standard height of 1U is 1.75 inches, which is 44.45mm. There are generally 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 88.9mm.

The specifications of the cabinets for industrial control cabinets and server cabinets are also the industry standard for this kind of generality. Generally it is 22U to 42U. The cabinet is also installed with a 1U height, detachable drag fixing bracket. Customers can flexibly adjust the height according to the design elevation of the industrial computer to store server cases, industrial control cases, and hub devices.

2. Differences in parts in the case

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 switching power supply and the heat pipe cooling system of the chassis. The 4U chassis has a large space and many air holes, and the exhaust fan that can be installed is more casual. The heat dissipation performance of the heat pipe is much better than that of the 2U chassis with relatively narrow space.

The temperature is too high, it is very easy to harm the characteristics of the chassis, so in the selection of industrial control chassis and server chassis, the fan heat of the chassis is also a very important reference standard. When a large amount of items must be placed in the case, only a 4U case can be placed.

3. The difference between appearance and drag pipe

The 2U chassis is relatively more compact and more beautiful than the 4U chassis. In addition, the 2U chassis occupies a small space, so the cost of towing is low, while the 4U chassis occupies a large space, so the cost of towing is higher. The vertical type is more expensive, but its heat pipe has good heat dissipation.

Therefore, in the case of purchasing 2U chassis and 4U chassis industrial control chassis or server chassis, it is necessary to comprehensively consider the factors at all levels and the additional costs that will be incurred after the purchase. Choose the most suitable 2U chassis or 4U chassis.
