Description

Technical Field

[0001] The present application relates to the technical field of inkjet printers, and in particular to a heat dissipation and exhaust system for inkjet printers. Background Art

[0002] An inkjet printer usually has a host and a nozzle system. The host includes two compartments, the lower compartment has an ink supply system, and the upper compartment has an electronic system. The host is connected to the nozzle system through a conduit containing multiple pipes and wires. The ink supply system pumps ink to the nozzle system under pressure. The nozzle system controls a portion of the ink droplets to be non-charged and recycles them to the ink supply system through a negative pressure recovery tank for recycling. The nozzle system controls another portion of the ink droplets to have different charges, and passes them through a high-voltage electrostatic field to cause them to be deflected. The deflected ink dots fall on the surface of the object to form characters or patterns.

[0003] When the ink supply system recycles the ink returned by the printhead system, some ambient air will be brought into the ink supply system under the action of negative pressure. If this air cannot be discharged in time, it will seriously affect the stability and operation of the ink supply system, causing the ink recovery and normal ink supply functions to fail. Therefore, an exhaust port is set on the ink supply system to facilitate the timely discharge of the air brought in when the ink is recovered.

[0004] Inkjet printers generally work continuously for a long time without interruption. The electronic components of the electronic system and the electronic devices in the ink supply system will generate heat. If the large amount of heat generated by these components cannot be discharged in time, the long-term high temperature environment will shorten the service life of the electronic components and devices, easily cause failures and damage to the electronic system, and affect the operating stability and work efficiency of the inkjet printer.

[0005] In order to solve the heat dissipation and exhaust problems of inkjet printers, a forced air cooling solution with a fan and heat dissipation holes is usually used. When the electronic system compartment adopts forced air cooling for heat dissipation, although an air filter is installed at the air inlet, a lot of dust will still enter the electronic system compartment, affecting the heat dissipation effect of the electronic system. In addition, since moisture in the air will also be brought into the electronic system compartment, it will cause hazards such as condensation and electrical breakdown, which is very likely to cause circuit failures and affect the service life of the electronic system. When the ink supply system compartment adopts forced air cooling for heat dissipation and exhaust, when the exhaust outlet of the ink supply system compartment is close to the air inlet of the electronic system compartment, the hot air discharged from the ink supply system compartment may also enter the electronic system compartment, and these hot gases will also cause greater corrosion hazards to the electronic components in the electronic system.

[0006] Some existing improved heat dissipation and exhaust solutions are that the ambient air enters the electronic system compartment after passing through the air filter, and a high-speed fan is installed on the partition between the electronic system compartment and the ink supply system compartment. The fan is used to guide the hot air in the electronic system compartment to the ink supply system compartment, forming a positive pressure in the ink supply system compartment, and then the hot air and hot gas are discharged to the outside of the inkjet printer box through the ventilation holes on the bottom plate of the ink supply system compartment. This design can reduce the dust from entering the ink supply system compartment, which is conducive to eliminating the hidden danger of dust entering the ink supply system, while reducing a heat dissipation fan.

[0007] However, the above solution does not solve the hidden danger of dust and moisture entering the electronic system compartment, but also brings new problems: first, the fan guides the hot air from the high electronic system compartment to the low ink supply system compartment, and then discharges the hot air out of the main unit through the lower air outlet, which does not conform to the heat dissipation principle and increases the heat dissipation power consumption, affecting the service life of the heat dissipation fan. Second, because the first problem will increase the ambient temperature of the ink supply system compartment to a certain extent, which is not conducive to the heat dissipation of the electronic components on the ink supply system and reduces the service life of the inkjet printer, so this is not a good heat dissipation solution. Summary of the invention

[0030] The embodiment of the present application provides a heat dissipation and exhaust system for an inkjet printer, which can solve the problems in the related art that the heat dissipation of inkjet printers is poor, and dust and moisture can easily cause circuit failures, affect the operating stability of the inkjet printer, and reduce the service life of the inkjet printer.

[0031] See also Figure 1 , Figure 2 and Figure 4 As shown, the embodiment of the present application provides a heat dissipation and exhaust system for a printer, which is arranged on the main chassis 1 of the inkjet printer, and the main chassis 1 is a metal shell structure. An ink supply system compartment 10 and an electronic system compartment 20 for accommodating an ink supply system 3 are arranged in the main chassis 1 of the inkjet printer. The electronic system compartment 20 is located in the upper half of the main chassis 1, and the ink supply system compartment 10 is located in the lower part of the main chassis 1. The electronic system compartment 20 and the ink supply system compartment 10 are separated from each other by a partition 8.

[0032] The electronic system compartment 20 is a fully enclosed compartment, and the entire rear wall of the electronic system compartment 20 is set as a radiator 5. The radiator 5 is provided with a first air guide channel 602 and a first air guide outlet 603 for exhausting the air in the ink supply system compartment 10 to the outside of the main chassis 1. The first air guide channel 602 and the first air guide outlet 603 on the radiator 5 are interconnected and completely isolated from the electronic system compartment 20. The first air guide channel 602 is located above the ink supply system compartment 10 and is connected to the inside of the ink supply system compartment 10. The first air guide outlet 603 is located above the first air guide channel 602, and the outlet direction of the first air guide outlet 603 is toward the outside of the main chassis 1.

[0033] The side of the radiator 5 facing the inside of the electronic system compartment 20 is provided with a plurality of internal heat absorbing ribs 51 for heat exchange with the air inside the electronic system compartment 20, and the side of the radiator 5 facing the outside of the electronic system compartment 20 is provided with a plurality of external heat dissipating ribs 53. The plurality of internal heat absorbing ribs 51 provided on the side of the radiator 5 facing the inside of the electronic system compartment 20 constitute the convection and radiation heat absorbing surface of the electronic system compartment 20; the plurality of external heat dissipating ribs 53 provided on the side of the radiator 5 facing the outside of the electronic system compartment 20 constitute the convection and radiation heat dissipating surface between the electronic system compartment 20 and the ambient air outside the main chassis 1.

[0034] In some alternative embodiments: See Figure 1 and Figure 2 As shown, the embodiment of the present application provides a heat dissipation and exhaust system for a printer, wherein a plurality of internal heat absorbing ribs 51 of the heat dissipation and exhaust system for the printer are arranged in a horizontal direction from top to bottom in sequence, and two adjacent internal heat absorbing ribs 51 form a guide channel, and an internal heat absorbing boss 52 is provided in the guide channel, and the internal heat absorbing boss 52 can not only change the flow direction of the airflow in the guide channel, but also increase the heat absorption area of ​​the radiator 5;

[0035] The plurality of external heat dissipating ribs 53 are arranged in sequence from left to right in a vertical direction. The external heat dissipating ribs 53 , the internal heat absorbing ribs 51 , the internal heat absorbing bosses 52 and the radiator 5 are an integrally cast structure of aluminum alloy.

[0036] In some optional embodiments: the side of the radiator 5 facing the electronic system compartment 20 is further provided with a cover plate 500 covering a plurality of internal heat absorbing ribs 51 and internal heat absorbing bosses 52, and the cover plate 500 is mounted and fixed on the radiator 5;

[0037] The cover plate 500 and the radiator 5 together form a second air guide channel 502. The cover plate 500 is provided with a second air guide inlet 501 and a second air guide outlet 503 which are in communication with the electronic system compartment 20. The second air guide inlet 501 and the second air guide outlet 503 are spaced apart from each other on the cover plate 500 to form a longer second air guide channel 502, thereby increasing the heat dissipation area of ​​the second air guide channel 502.

[0038] A second fan 7 is provided at the second air guide inlet 501 to guide the air circulation in the electronic system compartment 20 to flow into the second air guide channel 502;

[0039] A temperature switch (not shown) for detecting the ambient temperature in the electronic system compartment 20 is provided in the electronic system compartment 20 . The temperature switch directly controls the switching of the second fan 7 .

[0040] The embodiment of the present application sets a temperature threshold in the electronic system compartment 20. For example, when the temperature in the electronic system compartment 20 is higher than 38°C, the second fan 7 is started through the temperature switch, and when the temperature in the electronic system compartment 20 is lower than 30°C, the second fan 7 is stopped, so as to ensure that the electronic devices can operate at an appropriate temperature and reduce the power consumption of the equipment.

[0041] In some alternative embodiments: See Figure 1 and Figure 2 As shown, an embodiment of the present application provides a heat dissipation and exhaust system for an inkjet printer, wherein a first air guide channel 602 of the heat dissipation and exhaust system of the inkjet printer extends into the ink supply system compartment 10, and the first air guide channel 602 is provided with a first air guide inlet 601 communicated with the ink supply system compartment 10, and the first air guide inlet 601 is provided with a first fan 6 that discharges the air in the ink supply system compartment 10 to the outside of the main chassis 1.

[0042] In some alternative embodiments: See Figure 1 , Figure 3 and Figure 4 As shown, the embodiment of the present application provides a heat dissipation and exhaust system for a printer, wherein a first air inlet 100 for introducing air into an ink supply system compartment 10 is provided at the bottom of a main chassis 1 of the printer, a diverter plate 4 is provided above the first air inlet 100, an ink supply system 3 is located above the diverter plate 4 and is parallel to the bottom of the main chassis 1, and an air filter 2 for filtering the air entering the ink supply system compartment 10 from the first air inlet 100 is provided between the diverter plate 4 and the first air inlet 100;

[0043] The splitter plate 4 is spaced apart from the bottom of the main chassis 1 to form a first air inlet splitter channel 101 , and the first air inlet splitter channel 101 directs the ambient air entering the ink supply system compartment 10 to flow upward from all around the ink supply system 3 .

[0044] The ink supply system compartment 10 is connected to the ambient air outside the main chassis 1 only through the low-positioned first air inlet 100 and the high-positioned first air guide outlet 603. The low-positioned cold air outside the main chassis 1 enters the ink supply system compartment 10 through the first air inlet 100, the air filter 2, and the first air inlet diversion channel 101. The cold air and the air exhausted by the ink supply system 3 and the heat dissipated during operation are guided by the first fan 6 into the first air guide inlet 601, flow along the first air guide channel 602, and are discharged from the first air guide outlet 603 to the outside of the main chassis 1. This process starts when the inkjet printer is turned on and ends when the inkjet printer is shut down.

[0045] above Figures 1 to 3 The arrows in the diagram indicate the direction of air flow.

[0046] In summary, the inkjet printer heat dissipation and exhaust system provided in the embodiment of the present application can completely prevent external dust and moisture from entering the electronic system compartment 20 because its electronic system compartment 20 is a fully enclosed compartment, thereby ensuring that the surface of the electronic components in the electronic system compartment 20 is dry and clean, and improving the working stability of the electronic components;

[0047] Since the entire rear wall of the electronic system compartment 20 is configured as a radiator 5, a plurality of internal heat absorbing ribs 51 and an internal heat absorbing boss 52 are arranged on the inner surface (i.e., the side facing the electronic system compartment 20) of the radiator 5 to form a second air guide channel 502 together with the cover plate 500, a second air guide inlet 501 and a second air guide outlet 503 are arranged on the cover plate 500, and a second fan 7 is arranged at the second air guide inlet 501, and the hot air in the electronic system compartment 20 is guided into the second air guide inlet 501 and the second air guide outlet 503 by the second fan 7. The air guide channel 502 transfers heat to the inner surface of the radiator 5, the inner heat absorbing ribs 51 and the inner heat absorbing boss 52 that are in contact with the hot air; since the multiple outer heat dissipation ribs 53 arranged on the side of the radiator 5 facing the outside of the electronic system compartment 20 constitute the convection and radiation heat dissipation surface between the electronic system compartment 20 and the external ambient air of the main chassis 1, the heat is transferred to the outer surface of the radiator 5 and the outer heat dissipation ribs 53 through the inner surface of the radiator 5, thereby dissipating the heat in the electronic system compartment 20 to the outside of the main chassis 1;

[0048] Since the radiator 5 is provided with a first air guiding channel 602 and a first air guiding outlet 603 which are interconnected and completely isolated from the electronic system compartment 20, a first air guiding inlet 601 is arranged below the first air guiding channel 602 and is connected to the inside of the ink supply system compartment 10, and a first fan 6 is arranged on the first air guiding inlet 601, so that the cold air at a low position outside the main chassis 1 enters the ink supply system compartment 10 through the first air inlet 100, the air filter 2, and the first air inlet diversion channel 101, and then the air exhausted by the ink supply system 3 and the heat dissipated during operation are guided by the first fan 6 into the first air guiding inlet 601, flow along the first air guiding channel 602, and are discharged to the outside of the main chassis 1 from the first air guiding outlet 603. This process also speeds up the removal of part of the heat transferred to the radiator 5 from the electronic system compartment 20, thereby achieving the optimization and enhancement of the heat dissipation of the electronic system compartment 20 while dissipating the heat of the ink supply system 3.
