Specifically, an embodiment of the axisymmetric vortex airflow generator of the cooling air duct of the fused deposition 3D printing nozzle of the present utility model includes four air outlets, wherein a first air outlet 1, a second air outlet 2, a third air outlet 3 and a fourth air outlet 4 of the four air outlets are disposed on the radiator. The characteristic designs of the four air outlets are the same, the air inlets of the four air outlets are the same in size and the air inlet quantity is the same, and the placement positions of the four air outlets are symmetrically opposite around the 3D printing spray head.
The cooling fan forms clockwise airflow vortex around the lower part of the spray head under the guidance of the four air outlets by the wind blown out from the air outlets by the radiator, thereby achieving the effect of cooling and radiating by omnidirectional vortex. Under the holding of the radiating effect of the omnidirectional vortex cooling, the fused deposition type 3D printer can successfully print an arm-spread structure with an included angle of 0-85 degrees with the vertical direction under the condition of no support, so that dead angle free radiation is realized, the structural reliability of a 3D printing model is enhanced, phenomena of wiredrawing, curling, thermal deformation, bridging sagging and the like are further reduced, and the success rate of 3D printing is improved.
The structure and the working principle of the axisymmetric vortex airflow generator of the cooling air duct of the fused deposition 3D printing nozzle are described below by taking the first air outlet 1 as an example.
In one embodiment of the axisymmetric vortex airflow generator of the cooling air duct of the fused deposition 3D printing nozzle, a guide vane 7 is arranged at the air outlet position of the first air outlet 1, and the guide vane 7 is horizontally arranged from top left to bottom right.
In this embodiment, one of the guide vanes has a certain guiding function on the air flow, and the other one of the guide vanes divides the air outlet into two parts.
Specifically, as shown in fig. 4, in this embodiment, the air guiding sheet 7 divides the first air outlet 1 into an upper air opening 5 and a lower air opening 6, in the horizontal direction, the air guiding sheet 7 is oriented from top left to bottom right, the air opening oriented in the same direction as the air guiding sheet 7 is the upper air opening 5, the air opening oriented at an acute angle to the air guiding sheet 7 is the lower air opening 6, and the air inlet of the upper air opening 5 is smaller than the air inlet of the lower air opening 6.
The opening of the upper air opening 5 is inclined from top left to bottom right, and is the same as the direction of the guide vane 7, and the opening of the lower air opening 6 is horizontal and forms an acute angle with the direction of the guide vane 7; in the vertical direction, the opening direction of the first air outlet 1 is inclined downwards by a certain angle.
In this embodiment, the lower air port of the first air outlet 1 is a straight air port, and forms a clockwise vortex heat dissipation air flow with the air flows of the second air outlet 2, the third air outlet 3 and the fourth air outlet 4.
Because 3D printer is in the printing process, the direction of movement of shower nozzle 8 is mostly clockwise (from down looking up), consequently the last wind gap 5 of first air outlet 1 is from upper left to right down oblique wind gap, and the lower wind gap of first air outlet 1 is the straight wind gap, and then forms clockwise swirl heat dissipation air current with the air current of other air outlets, is favorable to the air current to dispel the heat along the direction that the shower nozzle removed.
Further, in this embodiment, the tuyere length of the upper tuyere 5 is longer than the tuyere length of the lower tuyere 6. The longer uptake 5 is on the one hand to avoid premature escape of diagonal wind coming out of the uptake 5 and on the other hand to avoid interference with straight wind coming out of the other outlets.
Further, in the embodiment, in the horizontal direction, the inclined air port design of the air port 5 makes the air flows staggered, so that the heat dissipation effect is prevented from being reduced due to the opposite impact of the air flows; the straight air port design of the lower air port 6 can prevent the air flow from interfering with the air flow of other air outlets while enabling the air flow from the lower air port 6 to integrate the air flow of the upper air port 5.
Further, as can be seen in fig. 5, the first air outlet 1 is inclined downward by about 15 ° in the vertical direction, so that the flow direction of the air flow is directed to the lower side of the shower head 8, which is beneficial to heat dissipation of the consumable extruded from the shower head 8.
Further, as can be seen in fig. 6, since the four air outlets are symmetrically opposed in four directions, the air flows from the four air outlets are merged with each other to form a swirl air flow around the shower head 8. In fig. 7, it can be seen that, under the condition that the heat dissipation effect of the omnidirectional vortex cooling is maintained, the 3D printer can successfully print the arm-spread structure with the included angle of 0-85 ° with the vertical direction under the unsupported condition, thereby realizing dead-angle-free heat dissipation and enhancing the structural reliability of the 3D printing model. Meanwhile, phenomena such as wiredrawing, curling, thermal deformation, bridging sagging and the like are reduced, and the success rate of 3D printing is improved.
The axisymmetric vortex airflow generator of the cooling air duct of the fused deposition 3D printing spray head has the beneficial effects that: according to the technical scheme, the air-conditioning system comprises four air outlets, wherein a first air outlet, a second air outlet, a third air outlet and a fourth air outlet in the four air outlets are arranged on the radiator, and the cooling fan blows out air from the air outlets through the radiator, and forms clockwise airflow vortex around the lower part of the spray head under the guidance of the four air outlets, so that the omnidirectional vortex cooling and heat dissipation effects are achieved. Under the holding of the radiating effect of the omnidirectional vortex cooling, the fused deposition type 3D printer can successfully print an arm-spread structure with an included angle of 0-85 degrees with the vertical direction under the condition of no support, so that dead angle free radiation is realized, the structural reliability of a 3D printing model is enhanced, phenomena of wiredrawing, curling, thermal deformation, bridging sagging and the like are further reduced, and the success rate of 3D printing is improved.
The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the specification and drawings of the present utility model or direct/indirect application in other related technical fields are included in the scope of the present utility model.
