Server and chassis thereof
A server includes a chassis and a plurality of hard disk drive modules. The chassis includes a body, a partition, a cover plate, and at least one sound deadening structure. The body includes an opening and an accommodating space. The partition is disposed at the opening. The partition includes a first side surface, a second side surface opposite to the first side surface, and at least one flow channel. The first side surface faces the accommodating space, and the flow channel penetrates the first and the second side surfaces. The cover plate is disposed at the opening. The cover plate includes a plurality of ventilation holes. The sound deadening structure is disposed between the second side surface of the partition and the cover plate. The sound deadening structure includes a sound absorbing element and a reflecting element. The hard disk drive modules are accommodated in the accommodating space.
