Yang Hua cools down the consumptive material above nozzle using liquid circulation chamber, and between liquid circulation chamber and heat block
Heat insulation is set, heat effect of the heat block to liquid circulation chamber is prevented.Li Junmei etc. is using cooling circulating water water tank as cold
But the water-cooling apparatus of nozzle, feed pipe are located on water tank central axes, and water inlet pipe and outlet pipe are split in feed pipe both sides.On
The method of stating is all made of radiator liquid to cool down radiator, trunnion, but is the failure to consider the heat along gap between material silk and trunnion
The heat radiation problem of conduction and nozzle, while cooling liquid is directly injected into, flows out heat-dissipating cavity, can cause the trembling of nozzle, lead
It causes printer model surface to generate ripple, influences print quality.
