The invention provides a cooling device for a
laser 3D printer. The cooling device comprises a 3D printer body, a lifting table, a
laser head, a middle partition conduction mechanism, a
heat transfer circulation flow part, a
backflow supply part and an
air cooling module. The lifting table is arranged in the 3D printer body, the
laser head is arranged on the lifting table, the middle partition conduction mechanism is arranged on the lifting table and the laser head, and the
heat transfer circulating flow part is arranged on the 3D printer body, the lifting table and the middle partition conduction mechanism. The
backflow supply part is arranged on the
heat transfer circulation part, and the
air cooling module is arranged on the 3D printer body; according to the cooling device for the laser 3D printer, a heating source is accurately, effectively and stably cooled for a long time in an efficient heat dissipation mode,
heat transmission is fundamentally reduced, an
air cooling module is used for assisting with traditional air cooling heat dissipation, it is guaranteed that the excellent
cooling effect is obtained under the combined action of double measures, and the
cooling effect is improved. The temperature in the 3D printer body is practically and effectively controlled within a reasonable range, and stable work and high-quality printing of the 3D printer body are ensured.
