Description

Technical Field

[0001] The utility model relates to the technical field of printer heat dissipation, in particular to a heat dissipation mechanism for a flat printer. Background Art

[0002] The internal components of the printing equipment are relatively delicate and easily affected by high temperatures. When the ambient temperature is too high, the heat of the electronic components inside the printing equipment is difficult to dissipate, which can easily cause control board failures and affect life and printing performance. Generally, the printer's working environment temperature is maintained at 20-25°C and the relative humidity is maintained at 40%-70%, which is beneficial to the printer equipment system. In addition, if an inkjet printer is used, when the temperature is too high, it will accelerate the evaporation of ink near the print head, which is easy to cause blockage. When the temperature is too high, it often causes paper deformation, causing paper jams, jams, etc. At present, printing equipment is equipped with a special heat dissipation mechanism. However, in actual use scenarios, the heat dissipation mechanism generally has the following technical problems:

[0003] Most of the existing printer heat dissipation mechanisms achieve the purpose of heat dissipation by installing a cooling fan to discharge the internal high-temperature gas. However, no targeted improvement is made to the air humidity in the printer or print head area. In view of this, a heat dissipation mechanism for a flat printer that can both cool and dissipate heat and dehumidify is proposed. Utility Model Content

[0004] In order to solve the technical problem of heat dissipation of a printer nozzle, the utility model provides a heat dissipation mechanism for a flat printer.

[0005] The utility model is implemented by the following technical scheme: a heat dissipation mechanism for a flat printer, comprising a printer and a three-stage nozzle fixing device, the inner side of the three-stage nozzle fixing device is fixedly connected with a mounting plate, the upper side of the mounting plate is fixedly connected with a collecting platform, the upper side of the collecting platform is fixedly connected with a cooling water tank, the inner side of the cooling water tank is provided with a tapered threaded pipe, the printer is provided with a nozzle mounting mechanism for moving the three-stage nozzle fixing device, the collecting platform is provided with a gas collecting mechanism for facilitating the delivery of hot flow gas into the tapered threaded pipe, the upper side of the cooling water tank is provided with a gas pumping mechanism for extracting gas from the tapered threaded pipe, the lower end of the mounting plate is provided with a condensed water collecting mechanism for collecting liquid water after condensation of the gas, the outer side of the cooling water tank is provided with a heat sink mechanism for dissipating heat by increasing the contact area, and one side of the cooling water tank is provided with a liquid inlet pipe for adding coolant.

[0006] As a further improvement of the above solution, the nozzle installation mechanism includes a guide rail beam fixedly connected to the upper side of the printer, and the guide rail beam is slidably connected to the three-section nozzle fixing device.

[0007] As a further improvement of the above solution, the gas collecting mechanism includes an upper groove opened on the inner side of the collecting platform, and the upper end of the upper groove is connected to the lower end of the tapered threaded tube.

[0008] As a further improvement of the above scheme, the gas pumping mechanism includes an air collecting hood connected to the upper end of the cooling water tank, the inner side of the air collecting hood is fixedly connected to a docking bucket connected to the upper end of the conical threaded pipe, and the upper side of the air collecting hood is fixedly connected to a fan assembly.

[0009] As a further improvement of the above scheme, the condensate collection mechanism includes a fixing plate fixedly connected to the lower side of the mounting plate, and a water collecting funnel is fixedly connected to the lower end of the fixing plate. The maximum projection area of ​​the upper end of the water collecting funnel is larger than and completely covers the maximum projection area of ​​the lower end of the upper groove, and the lower end of the water collecting funnel is connected to a rubber tube.

[0010] As a further improvement of the above solution, the heat sink mechanism includes a plurality of heat sinks fixedly connected to the outside of the cooling water tank, and the plurality of heat sinks are in the shape of long plates and are evenly and symmetrically distributed.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model arranges a tapered threaded pipe inside the cooling water tank. When the hot air flow caused by the nozzle below flows through the tapered threaded pipe, it condenses into water when it is cold, which not only transfers heat to the coolant in the cooling water tank, but also removes moisture in the air to achieve a dehumidification effect. The heat sink added to the periphery of the cooling water tank can improve the heat dissipation performance of the cooling water tank.

[0013] 2. The utility model arranges a tapered threaded pipe inside the cooling water tank. Since the lower side of the cooling water tank is close to the heat source of the printer nozzle, the temperature of the lower side of the cooling water tank is relatively high. In addition, the contact area of ​​the lower end of the tapered threaded pipe in the cooling water tank is also relatively large, which increases the efficiency of heat diffusion in the air flow to the lower part of the cooling water tank, resulting in a higher temperature of the coolant in the area below the cooling water tank. According to the principle of thermal expansion and contraction, the coolant with a high temperature at the bottom flows upward, thereby forming a strong convection effect in the upper and lower directions of the entire cooling water tank, thereby increasing the heat absorption and heat dissipation capabilities of the entire device.

[0021] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0022] Example:

[0023] Please combine Figure 1-Figure 5 A heat dissipation mechanism for a flat printer in this embodiment includes a printer 1 and a three-stage nozzle fixing device 3. A mounting plate 10 is fixedly connected to the inner side of the three-stage nozzle fixing device 3. A collecting platform 9 is fixedly connected to the upper side of the mounting plate 10. The collecting platform 9 is mainly in direct contact with the hot gas flow below and has a certain height, which is convenient for opening an upper groove 14. The upper port of the upper groove 14 is located at an eccentric position, and the lower port is circular. A cooling water tank 4 is fixedly connected to the upper side of the collecting platform 9. A conical threaded pipe 16 is arranged on the inner side of the cooling water tank 4. The printer 1 is provided with a nozzle mounting mechanism for moving the three-stage nozzle fixing device 3, a gas collecting mechanism for conveniently delivering the hot flow gas into the tapered threaded tube 16 is provided on the collecting table 9, a gas pumping mechanism for extracting the gas in the tapered threaded tube 16 is provided on the upper side of the cooling water tank 4, a condensed water collecting mechanism for collecting liquid water after the gas is condensed is provided at the lower end of the mounting plate 10, a heat sink mechanism for dissipating heat by increasing the contact area is provided on the outer side of the cooling water tank 4, and a liquid inlet pipe 5 for adding coolant is provided on one side of the cooling water tank 4.

[0024] Please combine Figure 1As shown, the nozzle installation mechanism includes a guide rail beam 2 fixedly connected to the upper side of the printer 1, and the guide rail beam 2 is slidably connected to the three-stage nozzle fixing device 3. The product is a combination of steel and aluminum, which reduces the weight. The accuracy of the printing plane utilizes the strength difference between aluminum and steel, and the fixed opening adopts the minimum value of the inner diameter of the thread, which reduces the thread opening process, improves efficiency and reduces costs, and also ensures the installation accuracy of the product. The strength is guaranteed because it is a self-tapping method and is a tight fit. Parts with particularly high-intensity impact can be strengthened by lengthening screws and adding self-locking nuts.

[0025] Please combine Figure 3 As shown, the gas collection mechanism includes an upper groove 14 opened on the inner side of the collection platform 9, and the upper end of the upper groove 14 is connected to the lower end of the tapered threaded tube 16. The tapered threaded tube 16 adopts a copper tube structural component, wherein the copper tube is a traditional heat exchanger pipe material, has good thermal conductivity and strength, and is not easy to corrode. The copper tube has a long service life of more than ten years. At the same time, the copper tube surface is smooth and not easy to scale, which ensures the heat exchange efficiency. The tapered threaded tube 16 has a large heat dissipation area below the cooling water tank 4, resulting in a higher coolant temperature below the cooling water tank 4. The coolant can be pure water or other cooling media such as cooling oil. The water with a higher temperature flows upward due to thermal expansion and contraction, and eventually forms internal phenomena such as strong convection and eddy currents, which accelerates the heat exchange efficiency inside the coolant.

[0026] Please combine Figure 2 and Figure 3 As shown, the gas pumping mechanism includes an air collecting hood 7 connected to the upper end of the cooling water tank 4, the inner side of the air collecting hood 7 is fixedly connected to a docking bucket 15 connected to the upper end of a tapered threaded pipe 16, and the upper side of the air collecting hood 7 is fixedly connected to a fan assembly 6.

[0027] Please combine Figure 3 As shown, the condensate collection mechanism includes a fixing plate 11 fixedly connected to the lower side of the mounting plate 10, and a water collecting funnel 13 is fixedly connected to the lower end of the fixing plate 11. The maximum projection area of ​​the upper end of the water collecting funnel 13 is larger than and completely covers the maximum projection area of ​​the lower end of the upper groove 14, which can ensure that the condensate can fall into the water collecting funnel 13. The lower end of the water collecting funnel 13 is connected to a rubber tube 12.

[0028] Please combine Figure 1 and Figure 2 As shown, the heat sink mechanism includes a plurality of heat sinks 8 fixedly connected to the outside of the cooling water tank 4. The plurality of heat sinks 8 are in the shape of long plates and are evenly and symmetrically distributed.

[0029] The implementation principle of a heat dissipation mechanism for a flat printer in the embodiment of the present application is as follows: before use, the staff adds coolant to the cooling water tank 4 through the liquid inlet pipe 5, connects the rubber tube 12 to the wastewater collection box in the printer, starts the fan assembly 6, and the fan assembly 6 pushes the air to flow from the bottom to the top. Due to the heat generated by the circuit board at the printer nozzle, the space temperature and humidity of the airflow below the collection table 9 are relatively high. Under the action of the fan assembly 6, the airflow moves upward along the upper groove 14 and aligns with the lower end of the tapered threaded tube 16. The high-temperature airflow condenses into condensed water when it flows through the tapered threaded tube 16, flows out along the upper groove 14 at the lower end of the tapered threaded tube 16, and falls into the water collecting funnel 13. The condensed water collected in the water collecting funnel 13 flows out along the rubber tube 12. Part of the heat flow is discharged from the fan assembly 6, and the other part is diffused into the cooling water tank 4. The cooling water tank 4 dissipates heat through the outer heat sink 8. At the same time, the formation of condensed water achieves the effect of removing excess moisture in the air.

[0030] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
