发明名称 HEATER FOR EXTRUDER
摘要 A heater for an extruder is provided to perform cooling by a heat radiating pin formed at an outer surface and a channel formed inside at the same time while tightly contacting a heating surface to a barrel. A heater(50) for an extruder includes a heat radiator(51), a plurality of heat radiating pins(52), and a plurality of channels(53). The cylinder type heat radiator surrounds the outer surface of a cylinder type barrel(10). The heat radiating pins are projected in a ring shape at certain intervals on the outer surface of the heat radiator. The channels are formed inside the heat radiator to introduce outside air. The heat radiator is connected to a power supply and radiates heat by the power supplied from the power supply, and the heat is transferred to heat a resin material in the barrel.
