Referring to fig. 1, according to the present application, by studying the structure of the existing metal 3D printing water-cooling platform 10 and the contact condition between the existing metal 3D printing water-cooling platform 10 and an ingot in the cooling process, it is found that the main reason that the heat dissipation capability of the existing metal 3D printing water-cooling platform 10 is insufficient is that an air gap is formed on the upper surface and the lower surface (interface 1 and interface 2) of the cooling plate 112, and the air gap seriously hinders the ingot from dissipating heat to the cooling water. As shown in fig. 2:
the interface 1 is an interface between the upper surface of the cooling plate 112 and the ingot, and the air gap formed on the interface 1 is mainly caused by the deformation and upward arching of the upper surface of the cooling plate 112 under the local high-temperature baking of the ingot. The printed cast ingot is separated from the cooling flat plate 112 in the process of printing the cast ingot and the cooling flat plate 112 and in the cooling process after the printing is finished, and an air gap of millimeter or even centimeter level is formed.
The interface 2 is an interface between the lower surface of the cooling plate 112 and the cooling water, and the main reason for forming the air gap on the interface 2 is that, in addition to the above-mentioned upward arching of the upper surface of the cooling plate 112, what is more critical is that the water level of the cooling water is low, and the cooling water cannot directly contact with the lower surface of the upper cooling plate.
Based on the above research and analysis, please refer to fig. 3, the present application provides a metal 3D printing cooling device 100, which includes a cooling platform 110 and a plurality of water-cooling tubes 120, wherein the plurality of water-cooling tubes 120 are arranged on an upper surface of the cooling platform 110 at intervals.

Further, in the present application, the metal 3D printing cooling device 100 further includes two water distributors 130, where the two water distributors 130 are connected to two ends of the plurality of water-cooled tubes 120, and the water distributors 130 are located outside two sides of the cooling platform 110; the water separator 130 can facilitate water feeding and water discharging for the plurality of water cooling pipes 120 at the same time, and the operation is more convenient. In this application, water separator 130 is detachably connected to a plurality of water cooling tubes 120. Because after the metal melt is printed, the water cooling tube 120 is wrapped on the lower portion of the metal melt, and the water cooling tube 120 cannot be directly taken out, the water separator 130 is detachably connected with the water cooling tube 120, so that the water cooling tube 120 and an ingot wrapped with the water cooling tube 120 can be taken down together, and then the lower portion of the ingot is cut.
In addition, it should be further noted that the water-cooling tube 120 in the present application is made of an aluminum alloy, and particularly, an aluminum alloy similar to a printed metal melt may be selected for preparation, after the ingot is cut, the portion of the ingot containing the water-cooling tube 120 may be directly remelted, and the ingot may be reused by adjusting the texture component.
