Description
Technical Field
The utility model belongs to the technical field of the heat dissipation of 3D printer choke, concretely relates to semiconductor refrigeration piece radiator suitable for 3D printer choke is radiating.
Background
The throat of the FDM 3D printer is used for guiding consumables to enter a heating block and is connected with a nozzle, and the upper half section of the throat is usually connected with a radiator to isolate heat conduction; there are three main types of throats: the first one is a complete penetration type, and is used for directly inserting a far-end Teflon feeding pipe into a throat from the outside, penetrating the whole throat to the bottom and touching a nozzle; and the second method comprises the following steps: the feeding pipe is a non-complete penetration type, the far-end Teflon feeding pipe is connected to the upper end of the throat pipe, and the other section of Teflon pipe is used at the lower end of the throat pipe; and the third is that: the throat tube is a Teflon-free tubular throat tube, and is suitable for printing high-temperature consumables such as ABS, PETG and HIPS; in the printing process, the consumable is extruded into the throat pipe by the extruding mechanism or is pumped back from the throat pipe, the upper end of the throat pipe is provided with a radiator, and the lower end of the throat pipe is connected with the heating block and the nozzle; the throat pipe is made of metal materials, and the temperature of the inner wall of the throat pipe can be directly increased when the throat pipe is connected with the heating block, so that a radiator is required to be additionally arranged at the upper end of the throat pipe to isolate heat conduction. The heat dissipation mode of present choke all utilizes an aluminium system radiating block, and plus radiator fan dispels the heat to the choke, and this kind of heat dissipation mode has just led to present when printing low temperature consumptive material like PLA, TPU, can only use the first or the second to take the choke of teflon pipe, if uses the third kind not to take the choke of teflon pipe, will be owing to the heat dissipation is not enough, causes the consumptive material inflation in the choke, blocks up the choke, can't continue to print. So when your printer uses the throat of first or second kind, just can not print high temperature consumptive material such as ABS, PETG and HIPS for a long time, can cause the ageing of the teflon pipe in the throat. Therefore, if the low-temperature consumable material of the printer is replaced by the high-temperature consumable material, the non-Teflon tubular throat pipe needs to be replaced; when low-temperature consumables need to be printed, the throat pipe with the Teflon pipe needs to be replaced, which is very inconvenient.
