Multi-stage refrigeration data center machine room

The utility model relates to the technical field of data storage, in particular to a multi-stage refrigeration data center machine room which comprises a machine room body, a condensation box is fixedly connected to the center of the bottom end of the machine room body, a plurality of supporting columns are fixedly connected to the edge of the bottom end of the machine room body, and a containing cabin is formed in the machine room body. And the front end of the placing cabin extends out of the machine room main body, and a movable door matched with the placing cabin is movably mounted at the front end of the machine room main body. Air circulation in the containing cabin can be accelerated, the temperature in the containing cabin can be rapidly reduced, condensate water in the cavity can absorb heat of air entering the S-shaped condensation pipe, the flowing distance of hot air in the cavity can be increased through the S-shaped condensation pipe, meanwhile, the contact area of the hot air and the condensate
