Description

Technical Field

[0001] This utility model relates to the field of water cooling in 3D printing, and in particular to a 3D printing water cooling circulation auxiliary cooling structure. Background Technology

[0002] Currently, Chinese patent CN206170640U discloses a water-cooling auxiliary system for laminar flow plasma 3D printing equipment, relating to the field of 3D printing. It includes a control unit, a cooling water tank equipped with a circulating water pump, a solenoid valve, and a cooling circulation pipeline with a temperature detector at the water outlet. The inlet of the cooling circulation pipeline is connected to the outlet of the cooling water tank via the solenoid valve, and the outlet of the cooling circulation pipeline is connected to the inlet of the cooling water tank. A heat exchange device is installed in the cooling water tank. The circulating water pump, solenoid valve, temperature detector, and heat exchange device are all controlled by the control unit. This water-cooling auxiliary system for laminar flow plasma 3D printing equipment has a simple structure, high controllability, and can automatically control circulation and real-time cooling.

[0003] 3D printing, also known as additive manufacturing, is a technology that uses digital model files as a basis and employs powdered metals or plastics and other bondable materials to construct objects layer by layer. In contrast to traditional subtractive manufacturing, it can create objects with complex geometries that may be difficult or even impossible to process using traditional methods. However, most existing 3D printing water-cooled circulation-assisted cooling structures do not have pre-cooling features. The sudden entry of hot coolant into the cooling tank can create a large temperature gradient on the tank walls. This temperature difference can cause thermal stress within the cooling tank material. If the cooling tank is made of materials with a high coefficient of thermal expansion, such as plastics, repeated thermal stress can easily cause cracks or deformation. Furthermore, the entry of hot coolant into the cooling tank can lead to uneven temperature distribution within the tank, affecting the density distribution of the coolant. Utility Model Content

[0004] The main purpose of this invention is to provide a 3D printing water cooling circulation auxiliary cooling structure, which aims to solve the problem that most existing 3D printing water cooling circulation auxiliary cooling structures do not have a pre-cooling structure. When hot coolant suddenly enters the cooling tank, it will cause a large temperature gradient on the wall of the cooling tank. This temperature difference will cause thermal stress inside the cooling tank material. If the cooling tank is made of materials with a large coefficient of thermal expansion such as plastic, repeated thermal stress will easily cause it to crack or deform. Furthermore, the entry of hot coolant into the cooling tank can easily cause uneven temperature distribution inside the tank, affecting the density distribution of the coolant.

[0026] This invention provides a 3D printing water cooling circulation auxiliary cooling structure, which aims to solve the problem that most existing 3D printing water cooling circulation auxiliary cooling structures do not have a pre-cooling structure. When hot coolant suddenly enters the cooling tank, it will cause a large temperature gradient on the wall of the cooling tank. This temperature difference will cause thermal stress inside the cooling tank material. If the cooling tank is made of materials with a large coefficient of thermal expansion such as plastic, repeated thermal stress can easily cause cracks or deformation. Furthermore, the entry of hot coolant into the cooling tank can easily cause uneven temperature distribution inside the tank, affecting the density distribution of the coolant.

[0027] like Figure 1-5As shown in the figure, the present invention provides a 3D printing water cooling circulation auxiliary cooling structure, including a printer 1, a circulating cooling water tank 4 placed on the rear side of the printer 1, a pre-cooling mechanism 2 bolted to the top of the circulating cooling water tank 4, a heat dissipation component 3 bolted to the top of the pre-cooling mechanism 2, a fan box 5 provided on the top of the heat dissipation component 3, a fan assembly 6 provided on the inner wall of the fan box 5, a water inlet pipe 7 provided on the right side of the pre-cooling mechanism 2, and a water outlet pipe 8 provided on the front side of the circulating cooling water tank 4.

[0028] In the technical solution of this utility model, by setting up a printer 1, a circulating cooling water tank 4, a pre-cooling mechanism 2, a heat dissipation component 3, a blower box 5, a fan assembly 6, an inlet pipe 7, and an outlet pipe 8, the pre-cooling mechanism 2, installed on the top of the circulating cooling water tank 4, can initially cool the coolant entering the tank, effectively preventing hot coolant from directly entering the circulating cooling water tank 4, which could lead to problems such as excessively high coolant temperature, performance degradation, and accelerated evaporation. The heat dissipation component 3, in conjunction with the blower box 5 and the fan assembly 6, further enhances the heat dissipation effect, ensuring that the coolant temperature remains stable within a suitable range, which helps maintain good cooling performance. The inlet pipe 7 and the outlet pipe 8 facilitate the circulation of coolant within the system, thereby ensuring that the printer 1 can operate stably and efficiently during printing, reducing issues such as decreased print quality and equipment wear caused by temperature problems.

[0029] Please refer to the following: Figure 4 The pre-cooling mechanism 2 includes a heat-conducting column 203, a heat-conducting plate 202, and a cooling box 201. The surface of the heat-conducting column 203 is bolted to the inner wall of the cooling box 201, the top of the heat-conducting column 203 is bolted to the bottom of the heat dissipation assembly 3, the bottom of the heat-conducting column 203 is bolted to the top of the heat-conducting plate 202, and the surface of the heat-conducting plate 202 is bolted to the inner wall of the cooling box 201. In this embodiment, by setting the heat-conducting column 203, the heat-conducting plate 202, and the cooling box 201, the heat-conducting column 203 can conduct heat to the heat dissipation assembly 3, while the heat-conducting plate 202 can guide the coolant to flow in the cooling box 201, which is conducive to heat transfer, effectively reduces the coolant temperature, provides pre-cooled coolant for subsequent cooling cycles, and avoids the adverse effects of high-temperature coolant on the entire cooling system.

[0030] For further information, please continue to refer to [link / reference]. Figure 3The heat dissipation assembly 3 includes a heat sink 301 and a heat dissipation plate 302. The bottom of the heat sink 301 is bolted to the top of the heat dissipation plate 302, the bottom of the heat dissipation plate 302 is bolted to the top of the cooling box 201, and the bottom of the heat dissipation plate 302 is bolted to the top of the heat-conducting column 203. The top of the air box 5 is in contact with the bottom of the heat dissipation plate 302. In this embodiment, by setting the heat sink 301 and the heat dissipation plate 302, the combination of the heat sink 301 and the heat dissipation plate 302 in the heat dissipation assembly 3 increases the heat dissipation area, which can more efficiently dissipate the heat transferred from the heat-conducting column 203. The connection relationship between the heat dissipation plate 302 and the heat-conducting column 203 ensures the continuity of heat transfer. The contact setting between the air box 5 and the heat dissipation plate 302 further enhances the heat dissipation effect, allowing the coolant to be better cooled in the pre-cooling mechanism 2.

Figure 2 A connecting component 9 is fixedly connected to the left side of the cooling box 201, and a valve 10 is provided on the surface of the connecting component 9. In this embodiment, by setting the connecting component 9 and the valve 10, the connection component 9 and the valve 10 facilitate the control of the connection between the cooling box 201 and other parts, and the flow rate of the coolant can be adjusted as needed.

[0032] Please refer to Figure 2 A connecting pipe 11 is fixedly connected to the left side of the connecting component 9, and the bottom of the connecting pipe 11 is fixedly connected to the top of the circulating cooling water tank 4. In this embodiment, by setting the connecting pipe 11, the connecting pipe 11 connects the connecting component 9 to the circulating cooling water tank 4, so that the coolant flows to the cooling water tank after being cooled by the pre-cooling mechanism 2, ensuring the integrity of the coolant circulation path.

[0033] Additionally, please refer to Figure 2 A support block 12 is bolted to the top of the cooling box 201. A support plate 13 is bolted to the side of the support block 12 closest to the air box 5. The side of the support plate 13 closest to the air box 5 is bolted to the support plate 13. In this embodiment, by setting the support block 12 and the support plate 13, the support block 12 and the support plate 13 provide a stable support structure for the air box 5, ensuring the stability of the air box 5 during operation, thereby ensuring that the fan assembly 6 can work normally and maintain a stable heat dissipation airflow.

[0034] Additionally, please refer to Figure 3 A protective frame 14 is bolted to the top of the bellows 5, and a protective net 15 is bolted to the inner wall of the protective frame 14. In this embodiment, by setting the protective frame 14 and the protective net 15, the protective frame 14 and the protective net 15 protect the bellows 5, prevent external objects from contacting the fan assembly 6, avoid foreign objects from entering the bellows 5 and damaging the fan or affecting its normal operation, and extend the service life of the fan assembly 6.

[0035] Additionally, please refer to Figure 5A limiting component 16 is bolted to the left side of the printer 1. The inner wall of the limiting component 16 engages with the surface of the water inlet pipe 7 and the surface of the water outlet pipe 8. In this embodiment, by setting the limiting component 16, the limiting component 16 limits the water inlet pipe 7 and the water outlet pipe 8, keeping the water pipes in a stable position near the printer 1 and preventing them from shaking randomly during use.
