Connect, circular hole is provided with the middle of aluminium radiator；The air outlet socket airstream deflector of turbofan, constitutes cooler, the left air-out of airstream deflector
Mouth and the region of right air outlet alignment pointed cone lower end.
This kind of 3D printer shower nozzle, has the positive effect that compared with prior art：Because consumptive material has a softening
Point temperature, such as PLA（PLA）The softening temperature of consumptive material will ensure the temperature in feed device wire feed chamber in consumption at 60 DEG C
Below material softening point temperature；Thermal source during 3D printer shower nozzle normal work is from two aspects：One is head body（Aluminium is heated
Block）The up heat transfer of temperature, two is to produce heat when wire feeding motor runs in feed device；Conduit, trunnion are inserted in using trunnion
Head body can be prevented（Aluminium heat block）Heat it is up；Aluminium radiator is connected by aluminum strip with feed device, by axle stream wind
Fan air is flowed on aluminium radiator so that in the feed device that dissipates wire feeding motor heat, while being opened in the middle of aluminium radiator
There is one to return greatly, air is flowed by the circular hole against the wire feeding gear in feed device and U-shaped bearing, so as to take away feeding
In device wire feed chamber, the shell louvre for absorbing the air permeable feed device of heat is outwards discharged；The left air-out of airstream deflector
The forming and hardening that spins is accelerated in mouth and the region of right air outlet alignment pointed cone lower end, cooling；Therefore say, this kind of 3D printer shower nozzle ratio
Like product, its radiating sets more reasonable.
