Fuente: Wipo "BigData" The invention discloses a heat dissipation cabinet for big data analysis and processing and a heat dissipation method thereof, relates to the technical field of big data storage cabinets, and aims to solve the problem that an existing big data storage cabinet cannot be flexibly adjusted according to the gradient change of temperature. Six sliding mounting seats are arranged in the cabinet; storage disc integration frames are mounted at the upper ends of the sliding mounting seats; seven partition plates are arranged at the front ends in the storage disc integration frames; water cooling pipes are arranged in the partition plates; and the water cooling pipes are connected in series in a sealed mode. A temperature sensor is installed at the bottom of each storage disc integrated frame. A cooling cavity is formed in the upper end of the interior of the cabinet. Two air inlet fans are fixedly installed at the upper end of the cooling cavity and are communicated with the exterior of the cabinet. An evaporator is fixedly installed in the middle of the cooling cavity, and the evaporator communicates with the interior of the cabinet. An exhaust fan is installed at the lower end of the interior of the cabinet, and three cooling fans are fixedly installed at the rear end of the cabinet.
