Rapidly assembled and disassembled hard disk rack with heat dissipation function
PendingCN119541569Aquick releasequick changeReducing temperature influence on carrierCarrier casesMechanical engineeringPhysics
The invention relates to the technical field of quickly-disassembled hard disk racks with a heat dissipation function, and discloses a quickly-disassembled hard disk rack with a heat dissipation function, which comprises a hard disk box, and a plurality of placing cavities and an air guide cavity positioned on the right side of the plurality of placing cavities are formed in the hard disk box; a hard disk frame located on the inner side of the containing cavity is slidably connected to the interior of the hard disk box, a hard disk body is arranged in the hard disk frame, a quick release mechanism connected with the hard disk frame in a clamped mode is arranged in the hard disk box, an electromagnet is arranged on the rear side wall of an inner cavity of the containing cavity, and an air guide mechanism located on the inner side of the air guide cavity is arranged in the hard disk box. The quick disassembly and assembly hard disk frame with the heat dissipation function has the advantages of being good in heat dissipation effect and the like, and the problem that the heat dissipation effect of an existing heat dissipation structure is not ideal due to the fact that the heat dissipation structure of the existing hard disk frame is mostly located on one face of an independent support of a hard disk, and heat of the hard disk is mostly generated on the upper face and the lower face with large areas of the hard disk is solved.
