Hard disk and server with it

Abstract

The invention discloses a hard disk and a server with the hard disk, wherein the hard disk comprises a shell, a disk core assembly, a shielding can and a control circuit board, wherein the disk core assembly is arranged in the shell; the shielding can covers the exterior of the shell and limits a sealed isolation cavity between the shell and the shielding can; and the control circuit board is arranged in the isolation cavity and is connected with the disk core assembly. According to the hard disk disclosed by the invention, due to the arrangement of the shielding can, the control circuit board can be isolated from outside air and prevents from being in direct contact with the outside air so that the corrosion and the pollution of the external environment in the control circuit board are avoided, the integral service life of the hard disk is prolonged, the capability of resisting the severe environment is improved, and meanwhile, the control circuit board is not damaged.

Description

technical field [0001] The invention relates to the technical field of data centers, in particular to a hard disk and a server with the same. Background technique [0002] With the rising cost of energy and people's emphasis on green environmental protection, the demand for energy saving in data centers is becoming more and more intense. Under the premise of ensuring the safety and high-performance operation of IT equipment in the data center computer room, increasing the working temperature of the data center and using outdoor natural wind to cool the IT equipment in the data center has become a new energy-saving direction. However, polluting particles, nitrides, and sulfur in the outdoor air substances will increase the corrosion of equipment. If you want to use outdoor fresh air directly, the IT equipment inside the data center must have a high ability to withstand harsh environments. As a vulnerable component with a high failure rate in IT equipment, hard disks are eas...

This method has high maintenance costs, and humidity adjustment also consumes water resources and energy

[0004] The control circuit board of the hard disk in the traditional server is installed on the lower surface of the casing. In order to facilitate heat dissipation, it is directly exposed to the outside air without any protective measures. After being exposed to the air for a long time, the control circuit The board will be corroded by nitrogen oxides, which will reduce the life of the control circuit board. At the same time, it is very prone to short circuit and there is a fire hazard.
