But the water-cooling apparatus of spray head, feed pipe are located on water tank central axes, and water inlet pipe and outlet pipe are split in feed pipe two 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, will cause the trembling of nozzle, leads
It causes printer model surface to generate ripple, influences print quality.
