Description

Technical Field

[0001] This utility model relates to the field of heat dissipation device technology, specifically a heat dissipation device for a 3D printer. Background Technology

[0002] A 3D printer, or rapid prototyping machine, is a technology that uses a digital model file as a basis and employs powdered metal or plastic and other bondable materials to construct objects layer by layer. After printing, the object tends to contain high temperatures, requiring cooling to ensure its stability. Therefore, a heat dissipation device is needed to dissipate heat and cool the object.

[0003] Authorization Announcement No. CN210309058U discloses a 3D printer heat dissipation device, including a printer, a heat dissipation box shell, and a top cover. The heat dissipation box shell is located below the printer, and the top cover is fixedly installed on the upper surface of the heat dissipation box shell. A complex array of support plates is fixedly installed vertically inside the heat dissipation box shell. The complex array of support plates is arranged in three rows and two columns. The two columns of support plates divide the interior of the heat dissipation box shell into three parts, namely a first suction chamber, a cooling chamber, and a second suction chamber. The beneficial effects are: hot air exhausted from the printer's heat dissipation vent is drawn into the heat dissipation box by a negative pressure fan. After being cooled by heat exchange with cooling water in the circulation pipe, it is discharged from the exhaust vent. The discharged cold air blows down the lower surface of the printer, drawing out the hot air and blowing cold air to cool the printer. A gap is left between the upper surface of the heat dissipation box and the lower part of the printer to facilitate air circulation and accelerate the heat exchange between hot and cold air.

[0004] However, the above-mentioned and other typical existing technologies still have certain problems in use:

[0005] 1. The heat dissipation device for the 3D printer in this patent does not take into account external impurities and particles during use. Due to the action of the fan, these impurities and particles will be blown into the device and then into the 3D printer, affecting the normal operation of the 3D printer.

[0006] 2. The heat dissipation device of this patented 3D printer only removes heat by increasing the airflow speed of the 3D printer base during use. However, this method is slow and inefficient for the 3D printer base. Utility Model Content

[0031] By setting up a dustproof component 1, the device can effectively prevent dust while also allowing the dustproof net 105 to be easily pulled out and replaced.

[0032] In this embodiment, reference is made to Figure 1 and Figure 3 As shown, the water flow heat dissipation assembly 2 includes a heat dissipation main block 201, a base window 202 is fixedly connected to the top of the heat dissipation main block 201, a water pump 203 is installed on the inner bottom wall of the heat dissipation main block 201, a condenser 204 is installed at the output end of the water pump 203, a serpentine tube 205 is connected to the output end of the condenser 204, and one end of the serpentine tube 205 is connected to the input end of the water pump 203.

[0033] Among them, by setting up the water flow heat dissipation component 2, heat is carried away by water to achieve the cooling of the printer base and avoid the occurrence of cooling dead zones.

[0034] In this embodiment, reference is made to Figure 1 and Figure 4 As shown, the air-cooled heat dissipation assembly 3 includes a main body block 301, a connection hole 305 on the top of the main body block 301, a support plate 304 fixedly connected to the inner bottom wall of the main body block 301, a fan mounting bracket 302 fixedly connected to the top of the support plate 304, a heat dissipation fan 303 installed on the inner surface wall of the fan mounting bracket 302, a connecting rod 308 slidably connected to the top of the main body block 301, a dust cover 306 fixedly connected to the top of the connecting rod 308, a handle 307 fixedly connected to the top of the dust cover 306, a replacement main frame 101 set on the outer surface wall of the main body block 301, the replacement main frame 101 fixedly connected to the main body block 301, a heat dissipation main block 201 set on the inner bottom wall of the main body block 301, the heat dissipation main block 201 fixedly connected to the main body block 301, and an iron clamping rod 102 set on the top of the adsorption magnet 103, the iron clamping rod 102 magnetically connected to the adsorption magnet 103.

Then, the water pump 203 will pump it into the condenser 204 for cooling and then re-inject it into the serpentine tube 205 for cooling.
