Problems solved by technology
However, if the temperature of the nozzle is too high, it will cause other parts to dissolve and burn. Therefore, a cooling device is required to control the temperature of the nozzle within a certain range. At this stage, a cooling fan is usually installed at the nozzle, but the cooling fan installed in this way can only Heat dissipation at one position of the nozzle, resulting in uneven heat dissipation, which affects the effect of heat dissipation

Description
technical field [0001] The invention relates to the technical field of 3D printers, in particular to a heat dissipation mechanism of a print head of a 3D printer. Background technique [0002] A 3D printer is a kind of additive manufacturing equipment. After melting the printing material, the required three-dimensional model can be produced by controlling the position and speed of the material through a microcomputer. As one of the core components of the 3D printer, the nozzle of the 3D printer determines the quality of the molding to a large extent. The smoothness of the filament flowing out of the extrusion nozzle and the temperature of the filament directly affect the accuracy of 3D printing. However, if the temperature of the nozzle is too high, it will cause other parts to dissolve and burn. Therefore, a cooling device is required to control the temperature of the nozzle within a certain range. At this stage, a cooling fan is usually installed at the nozzle, but the co...
