Printing head spiral water-cooling heat dissipation device of 3D printer

Abstract

The invention provides a printing head spiral water-cooling heat dissipation device of a 3D printer. The structure of the device comprises an upper fixing table, a lower fixing table, a water-cooling sleeve, a water inlet pipe, a water outlet pipe, adapters, a water tank and a water pump, wherein a printing head is sleeved with the water-cooling sleeve, the water-cooling sleeve is fixed through the upper fixing table and the lower fixing table vertically, a square spiral channel is formed in the water-cooling sleeve, a water inlet and a water outlet are formed in the water-cooling sleeve, the water inlet is formed in the lower portion, the water outlet is formed in the upper portion, and a connecting water pipe and the water-cooling sleeve are connected through the button type adapter. The water tank and the water pump are arranged beside the water-cooling sleeve and the printing head, the water tank is arranged on the upper portion, the water pump is arranged on the lower portion, the water tank and the water pump are fixed through the upper fixing table and the lower fixing table, the water pump is provided with a water outlet which is connected with a water pipe through the adapter to supply water to the water-cooling sleeve, the water pump is provided with an on-off key and up and down keys, the up and down keys can adjust the water circulation rate of the water pump so as to control the printing head temperature of the printer, and a water inlet is formed in the upper portion of the water tank and connected with a pipeline through the adapter to receive water from the water-cooling sleeve so as to achieve waterway circulation. With the printing head spiral water-cooling heat dissipation device of the 3D printer, the problem that vibration generated by operation of a cooling fan in an air cooling heat dissipation device can seriously affect the forming quality of the 3D printer is solved.

Description

technical field [0001] The invention relates to the field of 3D printers, in particular to a spiral water-cooled heat dissipation device for a nozzle of a 3D printer. Background technique [0002] As one of the core components of the 3D printer, the nozzle of the 3D printer largely determines the quality of the molding. The smoothness of the filament flowing out of the extrusion nozzle and the temperature of the filament directly affect the accuracy of the 3D printing model. However, if the temperature of the nozzle is too high, other parts will be dissolved and burned, and when the printing is completed, it needs to be cooled quickly. Therefore, a heat sink is required to control the temperature of the nozzle within a certain range. At this stage, a cooling fan is usually installed at the print head, that is, air cooling is used to dissipate heat from the print head. However, during the printing process, the vibration generated by the operation of the cooling fan will ser...
