Description
Technical field
The present invention relates to heat abstractor field, more particularly to a kind of DLP projector heat abstractor for 3D printing.
Background technology
With the development of science and technology, 3D printing is more and more applied to industry, biology, chemical industry, machinery, aviation etc.
Field.Digital optical processing technique (DLP) is one of 3D printing forming technique, and it is the door that 3D printing opens innovation, at present, city
Occur much solidifying the 3D printer of liquid photosensitive resin using Digital Light Processor (DLP) projecting apparatus on field.
DLP projector belongs to high-grade, precision and advanced optical, mechanical and electronic integration product, and internal component is very sensitive to temperature, in addition interior
The complexity of cage structure, its own requirement to temperature is harsher, and the radiating efficiency for improving projector is very crucial.For 3D
The DLP projector of printing, it is often necessary to worked long hours in the state of high brightness, radiating that more need be good.City at present
The DLP projector of main flow is all that the light conversion efficiency of optical system is poor, causes projector's temperature using 200W or so bulb on face
Height is spent, internal heat dissipating insufficient space small plus fuselage, radiator fan power limited, easily causes to overheat.
The content of the invention
A kind of simple in construction present invention aims at providing, manufacturing cost is low, and the practical DLP for 3D printing is thrown
Shadow machine heat abstractor.
Its concrete technical scheme is as follows：
A kind of DLP projector heat abstractor for 3D printing, including heat-conducting block, heat conducting cover plate, fin, the heat conducting cover plate
It is fixedly connected with projector shell, hole is provided with heat conducting cover plate and is fixed with heat-conducting block；Heat-conducting block be higher by heat conducting cover plate 0.1mm with
On, heat-conducting block is in close contact with projector shell, and heat-conducting block one side is placed at projector's heat producing light sources, for exporting heat；Lead
The another side of hot block is fixedly connected with heat sink, and radiating is formed by the heat-conducting block, heat conducting cover plate, the heat sink that set from inside to outside
Passage, transmits heat, and the screwed hole of position correspondence is provided with heat sink and heat conducting cover plate, for by clamping screw by its with
Projector shell connects.
Further, described heat conduction stock material is copper either aluminium or aluminium alloy or copper alloy.
Further, the filling heat-conducting silicone grease between the shell and heat-conducting block of projector, between heat-conducting block and fin.
Further, the heat-conducting block and heat conducting cover plate are using CNC processing or Laser Processing or mould processing.
Further, heat conducting cover plate, heat-conducting block, heat sink can be also made by being integrally formed.
The advantage of the invention is that：
1. being radiated using contact, make heat conduction cushion block to measure for the maximum mercury lamp of DLP projector heating, make full use of DLP to throw
Limited space inside shadow machine, device is simple, compact-sized.
2. apparatus of the present invention, which are DLP projector, has increased a heat dissipation paths newly, the original ventilation and heat of projector is not destroyed
Module, after device installation, the cooling system of a whole set of significant effect improvement is formed with original ventilation and heat module.
3. the appearance and size that different DLP projector improves heat conduction cushion block and cover plate can be directed to, can meet any to be used for 3D
The radiating of the DLP projector of printing.
4. the fin that the present apparatus uses is the conventional fin of in the market, ready-made specification or custom-made can be used, its
Its part is processed using aluminium alloy, and heat conduction is good, cheap.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the side view of the present invention.
Embodiment
Below by preferred embodiment shown with reference to the accompanying drawings, the present invention is explained in detail, but the invention is not restricted to
The embodiment.
Structure as shown in Figure 1 is as follows：
A kind of DLP projector heat abstractor for 3D printing, including heat-conducting block, heat conducting cover plate, fin, the heat conducting cover plate
It is fixedly connected with projector shell, hole is provided with heat conducting cover plate and is fixed with heat-conducting block；Heat-conducting block be higher by heat conducting cover plate 0.1mm with
On, heat-conducting block is in close contact with projector shell, and is arranged at projector's heat producing light sources, for transmitting heat；Heat-conducting block
Another side is fixedly connected with heat sink, and heat dissipation channel is formed by the heat-conducting block, heat conducting cover plate, the heat sink that set from inside to outside,
Transmit heat, the screwed hole of position correspondence be provided with heat sink and heat conducting cover plate, for by clamping screw by itself and projection
Machine cage connection.
Further, described heat conduction stock material is copper either aluminium or aluminium alloy or copper alloy.
Further, the filling heat-conducting silicone grease between the shell and heat-conducting block of projector, between heat-conducting block and fin.
Further, the heat-conducting block and heat conducting cover plate are using CNC processing or Laser Processing or mould processing.
Further, heat conducting cover plate, heat-conducting block, heat sink can be also made by being integrally formed.
The present invention makes its caused heat accelerate conduction by setting heat-conducting block near heat producing light sources；And it is projector
Increase heat dissipation channel, Shi Zhengtai projectors are internally formed three-dimensional cooling system.The parts such as heat-conducting block, cover plate, heat sink
Assembling form is not limited to be bolted after being processed into more parts, also part can be used to be processed into an entirety or completely processing
Into forms such as entirety.
Above embodiment is merely illustrative of the technical solution of the present invention and unrestricted, although with reference to example to this hair
