High-density distributed storage server

The utility model relates to the technical field of servers, in particular to a high-density distributed storage server which comprises an external mechanism, an internal mechanism is fixedly mountedin the external mechanism, and a cover sealing mechanism is fixedly mounted at the top of the external mechanism. The external mechanism comprises a main cabinet, an air inlet hole, a first threaded hole, an integrated mainboard module, a main power supply module, a cooling fan group and a second threaded hole, the air inlet hole is formed in the bottom of the main cabinet, and the first threadedhole is formed in the main cabinet. According to the high-density distributed storage server, the heat dissipation holes are formed in the top of the cover plate and correspond to the air inlet holes,so that ventilation is smooth, the heat dissipation efficiency is improved, high-temperature damage to equipment is avoided, cold air directly blows the magnetic disk module, the mainboard module andthe power module through th
