Fecha de publicación: 31/03/2020 Fuente: Wipo "BigData" The utility model discloses a heat dissipation device for a big data server. The radiator comprises a radiating frame, a heat conduction pipe and an exhaust pipe, the heat dissipation frame comprisesa copper bottom plate, a copper pipe, a supporting beam, a shell and a plurality of sets of evenly-arranged cooling fins. The cooling fins are divided into two parts and distributed on the two sides of the copper bottom plate. The four sets of copper pipes are symmetrically distributed on the two sides of the copper bottom plate, the centers of the copper pipes are fixedly welded to the copper bottom plate and integrated with the copper bottom plate, the two sides of the copper pipes are fixedly welded to the two sides of the cooling fins respectively and penetrate through the multiple sets ofcooling fins, the two sets of supporting beams are distributed on the two sides of the shell, and a draught fan is installed in the shell. According to the big data server heat dissipation device, through the arrangement of the asbestos plate and the two sets of air outlet holes, after air containing heat is blown into the heat conduction pipe, the air can be separated by the asbestos plate and discharged from the two sets of air outlet holes, so that the heat is discharged in two different directions around, and the heat dissipation effect is improved.
