Photocuring 3D printer base heat dissipation structure

Abstract

The invention discloses a photocuring 3D printer base heat dissipation structure. The structure comprises a supporting piece and a first cooling component, and the cooling component comprises a driving assembly, a plurality of first cooling fins and a plurality of second cooling fins; the driving assembly is used for driving the first cooling fins and the second cooling fins to move synchronously; the first cooling fins and the second cooling fins are arranged on the same side of the light-emitting source, the first cooling fins and the second cooling fins are arranged at intervals, and the first cooling fins are attached to the light-emitting source; when the temperature in the base is lower than or equal to the room temperature, a gap is formed between the second cooling fins and the light-emitting source; and when the temperature in the base is higher than the room temperature, the second cooling fins are attached to the light-emitting source. According to the photocuring 3D printer base heat dissipation structure, through the first cooling fins and the second cooling fins, the contact area of the light-emitting source and the cooling fins is increased, then the heat dissipation efficiency of the light-emitting source is improved, the time of the 3D printer in a high-temperature state is shortened, and then the service life of the 3D printer is prolonged.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of a printer base, in particular to a heat dissipation structure of a light-cured 3D printer base. Background technique [0002] In the era of rapid technological development, people have higher and higher requirements for speed. In order to meet people's requirements, 3D printers have come out; 3D printers are a kind of machine of rapid prototyping technology. Bondable materials such as powdered metal or plastics are used to construct objects by layer-by-layer printing. [0003] In related technologies, because the 3D printer can quickly produce objects, the light source of the 3D printer located in the base will generate heat and needs to be dissipated. Usually, multiple air outlets are opened on the base, and then fans are installed at the air outlets. The heat emitted by the light source is emitted through the air outlet. [0004] In view of the related technologies mentioned above,...

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that when the fan rotates to dissipate heat, because the high-speed operation of the 3D printer causes the temperature to rise in a short period of time, the heat dissipation efficiency of the fan rotation is low, which will cause the 3D printer to be in a high temperature state for a long time, shortening the temperature of the 3D printer. service life
