Description

Closed gas and liquid internal circulation cooling system
Technical Field
The invention relates to the technical field of 3D printers, in particular to a closed gas and liquid internal circulation cooling system.
Background
3D printing is a novel rapid prototyping manufacturing technique. It is produced by multilayer superposition growth principle. The special structure obstacle that traditional machining can not realize can be overcome to it. The simplified production of any complex structural component can be realized. The existing 3D printing technology is divided into a hot melting plastic technology FDM; laser sintering molding technology; the light-cured liquid resin is cured in selective areas. The liquid resin selective area curing molding technology is further divided into: laser scanning imaging light curing technology (SLA); projector imaging illumination modeling (DLP); display screens image ultraviolet spectral light curing technology (LCD).
The LCD light curing principle is that the LCD imaging principle of the liquid crystal screen is utilized, and under the drive of a microcomputer and a display screen drive circuit, an image signal is provided by a computer program. Selective black and white areas appear on the liquid crystal screen, white is a light-transmitting area, and black is a light-shielding area.
Under the irradiation of a light source (generally high-frequency ultraviolet light with larger radiation energy), the obstruction of an image transparent area of the liquid crystal screen to the ultraviolet light is reduced, and the ultraviolet light can penetrate through the image transparent area; in a region where no image is displayed, ultraviolet rays are blocked. The ultraviolet light transmitted through the liquid crystal panel constitutes an ultraviolet image region.
A light-cured liquid resin groove is arranged on the surface of the liquid crystal screen, a transparent film is arranged at the bottom of the groove, ultraviolet light irradiates the liquid light-cured resin through the transparent film, the resin irradiated by the ultraviolet light is cured and reflected, and the irradiated liquid resin becomes a solid state. The opaque portion of the liquid crystal screen blocks ultraviolet light. The liquid light-curing resin of the shielded part is not irradiated by ultraviolet rays, and the part of the resin which is not irradiated still keeps liquid. The cured resin is the product molding part manufactured by our LCD photocuring 3D printer.
The LED ultraviolet light source array lamp beads are used as light sources of LCD photocuring 3D printer equipment, if the LED photocuring 3D printer equipment works in an open or semi-open environment, the LED photocuring 3D printer equipment is easily polluted by particles such as dust and the like, so that light spots are generated to influence the printing effect, in addition, if the light sources are selected to be closed, the luminous efficiency of the LEDs can only reach 30 percent due to the restriction of a packaging technology, a large amount of input electric energy is converted into heat, if the heat is not conducted out in time, junction temperature is increased, the luminous efficiency of a semiconductor is reduced, and therefore the aging of devices is accelerated, and even the devices are permanently disabled.
Therefore, there is a need to provide a closed gas and liquid internal circulation cooling system to overcome the above-mentioned drawbacks.
