[0002] 3D printers heat-melt metals, plastics and other materials and then superimpose them layer by layer. When working, it is necessary to complete the hot-melt operation of strip or powder materials in the nozzle, so that the nozzle has a high temperature, so that it is easy to Affecting the working safety of other mechanisms in the printer, it is necessary to use a cooling device to cool down the nozzle. The patent application number is CN202010483644.6, which discloses a cooling device for the nozzle of a 3D printer based on graphene interlayer heat exchange. Now Some 3D printing nozzle heat dissipation equipment basically has the advantages of stable operation and long service life, which can meet the needs of the 3D printer nozzle for cooling operations. However, for the existing 3D printing nozzle cooling equipment, on the one hand, in the heat dissipation During operation, when the heat dissipation rate is low, it is easy to cause the temperature in the nozzle to drop, which is not conducive to ensuring the hot-melt operation of printing materials and increasing energy consumption. When the heat dissipation rate is low, it is easy to cause the temperature inside the printer to be too high, which is not conducive to ensuring the machine body On the other hand, due to the small size of the print nozzle, the cooling water pipe is very thin when performing heat dissipation operations. When using cooling water for heat dissipation operations, fouling in the cooling pipe is prone to occur, resulting in Blockage is not conducive to ensuring long-term heat dissipation and reduces the service life of the nozzle. On the other hand, when cleaning the scaling in the pipeline, the nozzle needs to be disassembled to reduce the working efficiency of the nozzle, and the pipeline will fall off during work. The fouling of the dirt is easy to enter the radiator, causing the blockage of the radiator
