Description
Technical field
The utility model relates to a kind of radiator, especially a kind of 3D printer head radiator.
Background technology
3D printer is also known as three-dimensional printer, and it is a kind of based on mathematical model file, uses special wax material, powdery metal or plastics etc. can jointing material, manufactures three-dimensional object by the jointing material printed from level to level.Shower nozzle need be heated to certain high temperature melt to print silk material and print by 3D printer when printing, and prints silk material easy expansion crystallographic blocking conveying pipeline after being warming up to certain high temperature.Therefore one radiator need be set on printing head to prevent line temperature too high.Traditional 3d printer radiator adopts the shaping scheme of time processing, materials are that aluminium alloy or brass material radiating efficiency are high, but have that temperature ramp is fast, a surperficial problem such as rough of metal inner surface, cause problems such as increasing into thread resistance, temperature ramp is too fast in pipe fitting, temperature ramp still expanded by heating crystallization can cause plug wire to a timing printed material.
Utility model content
The purpose of this utility model is to improve the problem of existing 3D printer head radiator heat-dissipation poor effect in background technology.
In order to overcome the above problems, the utility model provides a kind of 3D printer head radiator, comprise columniform copper shell and built-in pipe fitting, described copper shell is installed with multi-layer heat dissipation sheet, described built-in pipe fitting comprises copper cored screw and heat insulation pipe fitting, described copper housing center is located in described copper cored screw, described copper cored screw is located in described heat insulation pipe fitting, on the outer wall that described copper cored screw and described copper shell are fitted, even spread has one deck heat conductive silica gel, and described heat insulation pipe fitting is the extraordinary teflon pipe of self-lubricating.
Described fin is copper disk, and described multi-layer heat dissipation sheet is evenly arranged on described copper shell.
The beneficial effects of the utility model are: adopt the heat radiation of multi-layer heat dissipation sheet, considerably increase the area of dissipation of radiator, increase heat conductive silica gel, can accelerate heat transfer, improve radiating efficiency, thus prevent conveying pipe fitting internal thread material temperature from spending high blocking conveying pipeline.Adopt self-lubricating extraordinary Teflon material simultaneously, reduce the resistance of silk material and pipe fitting inner wall, make printing consumables smooth pass through inner chamber.Teflon material also has resistant to elevated temperatures feature, therefore can resist thermal shock and reduce climbing of temperature in pipe fitting, prevent the material temperature from spending high blocking conveying pipeline further.The mode that in the utility model adopts, thermal resistance is dispelled the heat outward, improves the radiating efficiency of radiator greatly.
Accompanying drawing explanation
Accompanying drawing 1 is the schematic diagram of a kind of 3D printer head radiator described in the utility model.
Accompanying drawing 2 is top views of a kind of 3D printer head radiator described in the utility model.
Marginal data: 1, copper shell; 11, fin; 2, copper cored screw; 3, heat insulation pipe fitting; 4, heat conductive silica gel.
Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of 3D printer head of the utility model radiator is described further.
As shown in Figure 1 and Figure 2, the 3D printer head radiator of the present embodiment, comprise columniform copper shell 1 and built-in pipe fitting, copper shell 1 is installed with multi-layer heat dissipation sheet 11, built-in pipe fitting comprises copper cored screw 2 and heat insulation pipe fitting 3, copper shell 1 center is located in copper cored screw 2, copper cored screw 2 is located in heat insulation pipe fitting 3, on the outer wall that copper cored screw 2 and copper shell 1 are fitted, even spread has one deck heat conductive silica gel 4, and heat insulation pipe fitting 3 is the extraordinary teflon pipe of self-lubricating.During use, copper cored screw 2 connects printing head, high temperature in printing head easily conducts to notice cored screw 2, high temperature conducts to heat conductive silica gel 4 through copper cored screw 2, heat conductive silica gel accelerated heat is conducted, by heat conduction to copper shell, the heat of copper shell, through the heat radiation of multi-layer heat dissipation sheet, reaches the effect of cooling.Design multi-layer heat dissipation sheet can increase area of dissipation, improves radiating efficiency, thus prevents conveying pipe fitting internal thread material temperature from spending high blocking conveying pipeline.During printing, silk material enters printing head through heat insulation pipe fitting, melts and spray in printing head.Heat insulation pipe fitting have employed the extraordinary Teflon material of self-lubricating, reduces into a resistance, make printing consumables smooth pass through inner chamber.Because Teflon material also has resistant to elevated temperatures feature, therefore can resist thermal shock and to slow down climbing of temperature in pipe fitting, prevent the material temperature from spending high blocking conveying pipeline further.
In the present embodiment, fin 11 is copper disk, and multi-layer heat dissipation sheet 11 is evenly arranged on copper shell 1.Heat sink design is disk, easily installs and not easily scratch.When fin is evenly arranged, radiating effect is best after tested.The 3D printer head radiator heat-dissipation excellent in efficiency of the present embodiment and to enter a resistance little.
The utility model is not limited to above embodiment and conversion.
