[0002] A printer is one of the output devices of a computer, used to print the results of computer processing onto relevant media. The heating roller, pressure roller, motor and electronic components inside the printer generate a lot of heat when working, which causes the internal temperature of the printer to rise, thus affecting the print quality and the life of the device.
[0003] After prolonged use, the internal temperature of a printer rises. Users usually place a cooling fan next to it to dissipate heat. However, the cooling fan causes dust to swirl around the printer, and the heat dissipation effect is poor through the printer casing. Therefore, a heat dissipation device for printers is proposed to address these issues. Utility Model Content

[0028] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0029] Reference Figures 1 to 5 This application illustrates a heat dissipation device for a printer, comprising: a printer body 1 and a heat dissipation hole 2; the heat dissipation hole 2 is provided on one side of the printer body 1, and a heat dissipation component 3 is provided on the outside of the heat dissipation hole 2; the heat dissipation component 3 includes a fixing frame 31, a cooling fan 32, a dustproof mesh 33, a heat-conducting rod 34, and heat dissipation fins 35; the fixing frame 31 has ventilation holes on its surface and is attached to the outer surface of the printer body 1, the cooling fan 32 is installed inside the fixing frame 31, and the dustproof mesh 33 covers the outside of the fixing frame 31; one end of the heat-conducting rod 34 extends into the interior of the printer body 1 and contacts the core heat-generating component, and the other end is connected to the heat dissipation fins 35 to form a heat conduction path.
[0030] The dustproof mesh 33, covering the outside of the fixed frame 31, directly intercepts dust from entering the printer, solving the dust problem associated with traditional cooling fans. The heat-conducting rod 34 and the heat sink fins 35 form an active heat dissipation path from the inside to the outside, overcoming the limitations of the outer casing on heat dissipation efficiency. For example, the heat-conducting rod 34 can connect to high-temperature components such as the print head or circuit board, directly transferring heat to the external fins, where the cooling fan 32 accelerates airflow. The cooling fan 32 directs airflow through the ventilation holes of the fixed frame 31, reducing the surface temperature of the printer body; simultaneously, the heat sink fins 35 utilize air cooling to further release the heat transferred from the inside. This reduces dust intrusion, ensures the cleanliness of the printer's interior, and optimizes internal heat dissipation efficiency through heat conduction. Specifically, for example, during continuous printing, the temperature of the printing fuser unit in a laser printer can reach over 200°C; the heat-conducting rod can transfer this heat to the external heat sink fins, avoiding the problem of traditional external air cooling not reaching the interior.
[0031] Furthermore, the fixed frame 31 is connected to the printer body 1 via a disassembly assembly 6, which includes a support plate 61, a connecting plate 62, a rotating rod 63, and a hand-tightening bolt 64. Quick disassembly is achieved through the linkage of the rotating rod 63 and the hand-tightening bolt 64. The dustproof mesh 33 is detachably connected to the outside of the fixed frame 31 via Velcro 36.
[0032] The disassembly / assembly assembly 6 also includes a locking block 65 and a groove 66; both the rotating rod 63 and the connecting plate 62 have grooves 66 inside, and the locking block 65 is tightly fitted into the groove 66 on one side of the connecting plate 62. A hand-tightening bolt 64 is fixedly connected to one side of the locking block 65. The Velcro 36 facilitates maintenance, allows for flexible replacement of the dust filter 33, and allows users to periodically remove and clean the dust filter, preventing long-term dust accumulation and blockage of the ventilation holes. This can be done without tools.
[0033] As an example, such as Figure 1 and Figure 5As shown, a heat dissipation device for a printer includes a printer body 1 for printing documents and heat dissipation holes 2. A heat dissipation hole 2 is provided on one side of the printer body 1 for dissipating heat from its internal components. A heat dissipation assembly 3 is provided outside the heat dissipation hole 2. The heat dissipation assembly 3 includes a fixing frame 31, a cooling fan 32, a dust filter 33, a heat-conducting rod 34, cooling fins 35, and Velcro 36. A fixing frame 31 with several ventilation holes on its surface is tightly fitted to the outside of the printer body 1. Several cooling fans 32 are installed inside the fixing frame 31. A disassembly assembly 6 is provided on one side of the fixing frame 31. The disassembly assembly 6 includes a support plate 61, a connecting plate 62, a rotating rod 63, a hand-tightening bolt 64, a locking block 65, and a groove 66. The fixing frame 31... Several connecting plates 62 are fixedly connected to the top of the printer body 1. A support plate 61 is fixedly connected to one side of the printer body 1. A rotating rod 63 is rotatably connected to one side of the printer body 1. Grooves 66 are provided in both the rotating rod 63 and the connecting plates 62. A locking block 65 is tightly fitted in the groove 66 on one side of the connecting plate 62. A hand-tightening bolt 64 is fixedly connected to one side of the locking block 65. The hand-tightening bolt 64 and the rotating rod 63 are threaded together. The cooling fan 32 accelerates the air circulation inside and outside the printer body 1. In conjunction with the heat-conducting rod 34 and the heat dissipation fins 35, it increases the heat dissipation effect inside the printer body 1 and avoids the situation of dust overflowing when the fan is placed directly next to the printer body 1.
[0034] A flexible dustproof net 33 is tightly fitted to the outside of the fixed frame 31. Both the dustproof net 33 and the fixed frame 31 have Velcro 36 embedded on one side for easy dustproofing of the fixed frame 31 and easy disassembly and assembly of the dustproof net 33. A heat dissipation fin 35 is fixedly connected to the top of the fixed frame 31. Several heat-conducting rods 34 pass through the heat dissipation fin 35. One end of the heat-conducting rod 34 is inserted into the printer body 1 to increase the heat dissipation effect inside the printer body 1. A dustproof cover 4 with a filter screen in the middle is fixedly connected to the rear side of the heat-conducting rod 34. A sealing ring 5 is fixedly connected to the outside of the heat-conducting rod 34 to facilitate dustproofing and sealing of one end of the heat-conducting rod 34. The support plate 61 is tightly fitted to the fixed frame 31. Several positioning posts 7 are fixedly connected to one side of the fixed frame 31 to provide a positioning effect when the fixed frame 31 is installed.
[0035] During operation, the device is powered by an external power source. When using the printer's cooling system, first place the printer body 1 in a suitable position. When the printer body 1 is in operation, the heat generated by its internal components rises upwards. Because several heat-conducting rods 34 are located on the rear side of the printer body 1, some heat flows from the heat-conducting rods 34 to the outside of the printer body 1. Simultaneously, the heat dissipation fins 35 on the outer side of the heat-conducting rods 34 effectively dissipate heat. Since one end of the heat-conducting rod 34 has a dust cover 4 with a filter in the middle, dust is prevented from entering the printer body 1 from one end of the heat-conducting rod 34. When the printer body 1 has been used for a long time and the heat-conducting rods 34 are insufficient to dissipate heat, the cooling fan 32 is activated. The airflow generated by the cooling fan 32 blows into the printer body 1 through the heat dissipation holes 2, effectively dissipating heat from the internal components. At the same time, because several ventilation holes are opened on the surface of the fixing frame 31, the airflow inside and outside the printer body 1 is accelerated. To improve ventilation and achieve heat dissipation, a dustproof net 33 is attached to the outside of the ventilation holes of the fixed frame 31. When the dustproof net 33 needs cleaning after prolonged use, the user needs to hold one end of the dustproof net 33 and tear it off. At this time, the Velcro 36 on one side of the dustproof net 33 is away from the Velcro 36 on the side of the fixed frame 31, so the dustproof net 33 can be cleaned. Then, the cleaned dustproof net 33 can be installed through the Velcro 36. When the cooling fan 32 needs maintenance or repair after prolonged use, the fixed frame 31 needs to be disassembled. The user holds one end of the hand-tightening bolt 64 and rotates it, causing the locking block 65 to rotate and move towards the rotating rod 63 until the locking block 65 is completely moved into the groove 66 opened on the inner side of the rotating rod 63. Then, the rotating rod 63 can be moved to one side until it is away from the connecting plate 62. Then, the fixed frame 31 is held and moved backward, causing the positioning column 7 to be removed from the printer body 1 until the fixed frame 31 is completely removed, so that the cooling fan 32 inside can be repaired or maintained.
