技术领域technical field
本发明涉及3D打印领域，具体涉及一种3D打印机喷头的冷却装置。The invention relates to the field of 3D printing, in particular to a cooling device for a nozzle of a 3D printer.
背景技术Background technique
3D打印机的喷头作为3D打印机的核心部件之一，很大程度上决定了成型的质量。挤出嘴流出丝料的流畅程度和出丝的温度直接影响了3D打印的精度。但如果喷头温度过高会导致其他部件溶解烧毁，因此需要冷却装置将喷头的温度控制在一定的范围内，现阶段，通常是在喷头处安装散热风扇，但是这种方法安装的散热风扇只能对喷头的一个位置进行散热，导致散热不均匀，影响到了散热的效果。As one of the core components of the 3D printer, the nozzle of the 3D printer largely determines the quality of the molding. 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, other parts will be dissolved and burned. 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 Dissipating heat at one position of the nozzle leads to uneven heat dissipation, which affects the effect of heat dissipation.
