Description

Technical Field

[0001] The utility model relates to the technical field of 3D printer nozzle bases, in particular to a heat dissipation base for a printer nozzle. Background Technique

[0002] When a 3D printer performs a printing operation, the printing nozzle heats up to melt and deposit the printing material to create a layered structure of a three-dimensional object. During this process, the heat generated by the nozzle is mainly used to heat the printing material to a suitable state to make it flowable.

[0003] Chinese Patent No. CN220784885U discloses a heat dissipation base for a 3D printer nozzle, including a mounting base. A printer nozzle is provided at the top of the mounting base. A cavity is formed in the inner wall of the mounting base, and ventilation plates are fixedly installed on the outer surfaces of the upper and lower ends of the cavity. A plurality of rod-shaped fan mounting seats are fixedly installed in the inner wall of the mounting base. One end of a circular plate is movably installed with a shaft rod, and a plurality of groups of fan blades are fixedly installed on the outer surface of the shaft rod. One end of the shaft rod is connected to a motor, and the motor is fixedly connected to another circular plate. By driving the motor, the shaft rod rotates, so that the fan blades can generate air flow. And through the action of the ventilation plates, the air flow can flow up and down, thereby performing a heat dissipation function. And through the action of the ventilation plates, the air flow can flow up and down inside the base, which can ensure that the heat is evenly distributed inside the base, avoid hot spot aggregation, and further improve the heat dissipation efficiency. However, the above patent uses an air-cooled heat dissipation method. But air cooling mainly relies on the flow of air to take away a certain amount of heat. When the temperature of the flowing air is relatively high, the phenomenon of low heat dissipation efficiency will occur, reducing the working efficiency of the device. Therefore, we propose a heat dissipation base for a printer nozzle to solve the above problems. Content of the Utility Model
