Description
Technical field
The present invention relates to 3D printing associated machines field more particularly to a kind of inert gas coolings for 3D printing
Cooler.
Background technology
During metal 3D, the molding metal powder of laser printing be easy under the high temperature conditions with the oxygen in air
Oxidation reaction occurs, generates a large amount of flue dust, it is therefore desirable to be passed through the inert gases such as nitrogen or argon gas in closed molding room
Gas shield is carried out to metal laser printing shaping process, prevents metal powder high-temperature oxydation.But still have a small amount of flue dust production
Raw, these flue dust can be attached under the disturbance of thermal current on window mirror, or be diffused on laser formation face, and influence is directly connect
Laser emission goes out energy, and the quality of metal forming part is rung from face.If the protective gas with flue dust is directly sucked into
Outside type room, the waste of protective gas is not only caused, but also serious pollution is caused to environment.Therefore, indoor to being molded
Protective gas, which carries out circularly purifying recycling, can effectively reduce printing cost, while generate smaller pollution to environment, in gas
Into before filter device, it is necessary first to be cooled down to gas, can prevent high-temperature gas damage filtering dress
It sets, or even situations such as the filter core layer that ignites catches fire, the inert gas after in addition cooling down more can after coming back to printing container
Playing prevents metal powder high-temperature oxydation, ensures inert gas protective action.
Invention content
There is provided the invention aims to overcome the deficiencies in the prior art a kind of reasonable for structure, multiple-limb management design,
The inert gas for 3D printing that gas flow is big and cooling is efficient cools device.
In order to achieve the above objectives, present invention employs following technical solutions.
A kind of inert gas for 3D printing cools device, including cooling cylinder, air inlet, gas outlet, coolant liquid go out
Mouth, coolant inlet, connection flexible pipe, circulating pump, cooler bin, coolant liquid, heat sink, heat emission fan, positioning plate, location hole and cooling
Pipe, the front and back ends portion of the cooling cylinder is respectively arranged with air inlet and gas outlet；Cooling is installed on the side of the cooling cylinder
Liquid exports and coolant inlet；The cooling liquid outlet is connected after being connected with circulating pump, cooler bin successively by connection flexible pipe
It leads in coolant inlet；It is filled with coolant liquid in the cooler bin；The side of the cooler bin is equipped with heat sink；It is described to dissipate
Hot plate rear portion is installed with heat emission fan；The inside of the cooling cylinder is equipped with positioning plate；It is uniformly machined on the positioning plate
Location hole；Cooling tube is installed on the location hole；The quantity of the cooling tube is two or more.
As a further improvement on the present invention, the quantity of the positioning plate is two, and is separately mounted to the cooling cylinder
Inside at front and back ends position.
As a further improvement on the present invention, the coolant liquid uses anti-freeze cooling liquid.
Due to the application of the above technical scheme, the advantageous effects that the present invention has：Technical scheme of the present invention passes through
Using setting cooling liquid outlet and coolant inlet on cooling cylinder, and circulating pump, cooler bin, heat sink are connected with by hose
And heat emission fan, it is recycled between cooling liquid outlet and coolant inlet with coolant liquid may be implemented, and by continuous
Heat dissipation to cooler bin improves the advantageous effects of cooling efficiency；The technical program is used is arranged two inside cooling cylinder
Positioning plate, and intert on positioning plate and multiple cooling tubes are installed, in this way entrance will be split after air inlet entrance in gas
Each cooling tube, and coolant liquid is then filled in the space that cooling tube interlocks, have that gas flow is big, cooling contact area is big and
The advantageous effects of gas cooling good heat dissipation effect.
