How to Correctly Choose the Size of 4U Server Chassis?

The 4U server chassis size is the server's width (48.26cm=19 inches) and height (multiplied by 4.445cm). It is the same size as a 1U server chassis. The rack industrial control cabinet also conforms to the size of the 19-inch industrial control cabinet, and the thickness is based on 4.445cm.

Basic concept of 4U server chassis size

1U is equal to 4.445cm, 2U is twice as much as 1U8.89cm, and then 4U is 17.78cm. The change of the chassis structure reflects the change of the hardware system of the personal computer from the side. The changes in functions reflect consumers' requirements for the comfort and humanization of personal computers.

There are generally 2 or more CPUs used in a 4U chassis, plus the internal use of SCSI disk arrays. So the internal heating of the server is very large. A high-quality server chassis must have good heat dissipation; heat dissipation is mainly reflected in the number and location of fans, the rationality of heat dissipation channels, and the choice of chassis materials.

Depending on the size of the game case, large-diameter fans are used to directly cool the CPU, memory, and disk. This forms a good heat dissipation channel. From front suction to rear exhaust (in and out), forming a good thermal cycle system. This promptly removes a large amount of heat from the chassis and ensures the stable operation of the server. "The case shell made of high-quality aluminum alloy or steel material has strong thermal conductivity and can effectively improve the heat dissipation environment.
