Technical Field

[0002] In the field of UV curing lamp heat dissipation in printing presses, traditional heat dissipation methods mostly use single air cooling or liquid cooling.

[0003] When using air cooling alone, the airflow distribution is often uneven, leading to excessively high local temperatures in the UV curing lamp, which affects the curing effect and the lifespan of the equipment. When using liquid cooling alone, the heat exchanger has limited heat dissipation efficiency during the circulation process of the coolant, making it difficult to quickly transfer the heat in the coolant to the outside, causing the coolant temperature to gradually rise and making it unable to continuously and efficiently absorb the heat from the UV curing lamp.

[0004] Solving the technical problem of uneven airflow distribution and low heat exchanger efficiency, which leads to poor heat dissipation of UV curing lamps, is key to improving the performance of printing presses. Therefore, improvements are necessary. Utility Model Content

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] Reference Figures 1 to 4 As shown, a heat dissipation device for a UV curing lamp in a printing press according to the present invention includes a heat-conducting base 1, an air guide shroud 2, a liquid cooling pipe 3, a heat exchanger 4, and a cooling fan 5. The heat-conducting base 1 comes into contact with the UV curing lamp of the printing press to conduct heat from the UV curing lamp; it conducts heat through direct contact; it can effectively conduct away the heat generated by the UV curing lamp, providing a basis for subsequent heat dissipation.

[0023] The air guide shroud 2 is placed on top of the heat conduction base 1 to guide airflow to dissipate heat from the heat conduction base 1. The air guide shroud 2 is provided with an air inlet 21 for introducing gas and at least two air outlets 22 for dissipating gas. It can guide airflow to dissipate heat from the heat conduction base 1, increase the contact area between the airflow and the heat conduction base 1 and the heat dissipation range, and improve the heat dissipation efficiency.

[0024] The heat-conducting base 1 is provided with an air distribution section 11, and an air guide 12 is provided in the air distribution section 11 to guide the airflow entering the air inlet 21 to the two air outlets 22. By cooperating with the air distribution section 11 and the air guide 12, the airflow can be more evenly and reasonably distributed to different air outlets 22, further optimizing the heat dissipation effect of the heat-conducting base 1.

[0025] The liquid cooling pipe 3 passes through the air guide 12 and is connected to the heat exchanger 4. It is used to absorb the heat generated by the UV curing lamp through the circulating coolant and transfer it to the heat exchanger 4. It can absorb heat through the circulating coolant and quickly absorb the heat generated by the UV curing lamp and transfer the heat to the heat exchanger 4, thereby improving the heat transfer efficiency.

[0026] The heat exchanger 4 is located at the air inlet 21 and is used to transport coolant and circulate it in the liquid cooling pipe 3 and transfer the heat in the coolant to the outside air. The heat exchanger 4 is located in the gas flow path, which facilitates heat exchange between the incoming airflow and the heat exchanger 4. While transporting coolant and circulating it in the liquid cooling pipe 3, the heat in the coolant can be transferred to the outside air more efficiently, thus improving the efficiency of heat dissipation.

[0027] A cooling fan 5 is installed on the heat exchanger 4 to deliver gas for heat dissipation. By operating the cooling fan 5 to deliver gas through the heat exchanger 4, the heat dissipation effect of the heat exchanger 4 is enhanced, the heat exchange process between the heat exchanger 4 and the outside air is accelerated, and the heat exchanger 4 is ensured to continuously and effectively dissipate the heat in the coolant, thus maintaining the stable operation of the entire heat dissipation system.

[0028] The UV curing lamp generates a large amount of heat during operation. The heat-conducting base 1 comes into contact with the UV curing lamp, rapidly transferring the heat away. An air guide shroud 2 covers the top of the heat-conducting base 1, and outside air enters through the air inlet 21 of the shroud 2. Within the air distribution section 11 of the heat-conducting base 1, the air guide component 12 guides the airflow entering through the air inlet 21 to the air outlet 22 of the air guide shroud 2, providing air cooling for the heat-conducting base 1. Simultaneously, a liquid-cooling pipe 3 passes through the air guide component 12, where circulating coolant continuously absorbs the heat transferred from the UV curing lamp through the heat-conducting base 1 and flows to the heat exchanger 4 located at the air inlet 21. The heat exchanger 4 transfers the heat from the coolant to the incoming air, and the cooling fan 5 operates, delivering more air through the heat exchanger 4 to enhance the cooling effect. After cooling, the coolant returns to the liquid-cooling pipe 3 for continuous circulation, continuously cooling the UV curing lamp and ensuring stable equipment operation.

[0029] Reference Figure 2 As shown, the air guide 12 in this embodiment includes multiple first air guide plates 13 and multiple second air guide plates 14; Multiple first air guide plates 13 are spaced apart to form a first air guide channel 100, and multiple second air guide plates 14 are spaced apart to form a second air guide channel 200. The first air guide channel 100 and the second air guide channel 200 are connected. By connecting the first air guide channel 100 and the second air guide channel 200, effective gas flow can be achieved, which helps to improve the gas flow path and distribution.

[0030] Reference Figure 2As shown, in this embodiment, the first air guide plate 13 has first air equalization gaps 15 on both sides. These first air equalization gaps 15 prevent gas from being completely blocked by the first air guide plate 13 as it flows through, allowing it to pass through the gaps on both sides. By setting the first air equalization gaps 15, the gas can be distributed and flowed more evenly, avoiding excessive concentration of gas in local areas or the formation of flow dead zones, thereby improving the overall gas flow uniformity of the air guide component 12.

[0031] Reference Figure 2 As shown, a second gas equalization gap 16 is provided between the first gas guiding channel 100 and the second gas guiding channel 200 in this embodiment. The second gas equalization gap 16 prevents the gas flowing from the first gas guiding channel 100 from directly and centrally rushing into the second gas guiding channel 200, instead allowing it to transition and disperse through the gap. By providing the second gas equalization gap 16, the gas can be more evenly distributed as it flows from the first gas guiding channel 100 to the second gas guiding channel 200, avoiding airflow turbulence or excessively fast or slow local airflow speeds at the junction of the two channels, thereby improving the uniformity and stability of the gas guiding component 12.

[0032] Reference Figure 3 As shown, the heat exchanger 4 in this embodiment includes a heat sink 41, a microchannel cold plate 42, an external pipe 43, and a circulation pump 44.

[0033] The microchannel cold plate 42 is disposed inside the heat sink 41, and the input end of the microchannel cold plate 42 is connected to the upward return end of the liquid cooling pipe 3; allowing the high-temperature coolant flowing upward from the liquid cooling pipe 3 to enter the microchannel cold plate 42.

[0034] An external pipe 43 is located on the outside of the heat sink 41, and the input end of the external pipe 43 is connected to the output end of the microchannel cold plate 42, so that the external pipe 43 can receive the coolant after heat exchange by the microchannel cold plate 42.

[0035] The input end of the circulating pump 44 is connected to the output end of the external pipe 43, and the output end of the circulating pump 44 is connected to the drop delivery end of the liquid cooling pipe 3. This enables the circulating pump 44 to provide power for the flow of coolant, allowing the coolant to circulate between the external pipe 43 and the liquid cooling pipe 3.

[0036] In use, the high-temperature coolant flows upward through the liquid cooling pipe 3 back to the microchannel cold plate 42, where it exchanges heat with the heat sink 41 to achieve cooling. The cooled coolant then flows out through the external pipe 43 and is then powered by the circulation pump 44 to be transported back to the downward conveying end of the liquid cooling pipe 3, forming a complete coolant circulation loop. This effectively realizes the exchange and transfer of heat, improves heat exchange efficiency, and ensures the stable operation of the system.

[0037] Reference Figure 3 As shown, the microchannel cold plate 42 in this embodiment has two layers, which are arranged alternately. This alternate arrangement makes the flow path of the coolant more complex and dispersed as it flows through the two layers of microchannel cold plates 42, changing the conventional state of single-layer laminar flow of the coolant and increasing the contact area and contact time between the coolant and the microchannel cold plates 42. Through the structure of the two layers of microchannel cold plates 42, the heat exchange efficiency between the coolant and the microchannel cold plates 42 can be effectively enhanced, allowing heat to be more fully absorbed and dissipated by the microchannel cold plates 42, thereby improving the heat exchange performance of the entire heat exchanger 4 and enhancing the cooling effect on the heat-generating components.

[0038] Reference Figure 4 As shown, the cooling fan 5 in this embodiment is provided with an outer cover 51 for guiding airflow, and the outer cover 51 is positioned directly above the microchannel cold plate 42. The outer casing 51 is provided with an air inlet 511 and an air outlet 512, and the cooling fan 5 is located between the air inlet 511 and the air outlet 512. This gives the airflow a clear directionality. When the cooling fan 5 is running, it can draw in outside air from the air inlet 511 of the outer casing 51. After being accelerated by the cooling fan 5, the accelerated air is then directed to the microchannel cold plate 42 directly below through the air outlet 512.

[0039] By setting up an outer cover 51 with an air inlet 511 and an air outlet 512, and placing the cooling fan 5 between the air inlet 511 and the air outlet 512 and directly above the microchannel cold plate 42, the air can be effectively guided to flow in a directional manner, so that more air is concentrated and blown toward the microchannel cold plate 42, enhancing the convective heat transfer effect between the air and the microchannel cold plate 42, thereby improving the heat dissipation efficiency and removing the heat on the microchannel cold plate 42 more quickly.

[0040] Reference Figure 4 As shown, in this embodiment, a dust cover 513 is provided at the air inlet 511 of the outer cover 51 to prevent dust from entering the air inlet 511 of the outer cover 51. By providing a dust cover 513 at the air inlet 511 of the outer cover 51, dust is effectively prevented from entering the air inlet 511 of the outer cover 51, avoiding the accumulation of dust on components such as the cooling fan 5 and the microchannel cold plate 42, ensuring the normal operation of the cooling fan 5 and the good heat dissipation performance of the microchannel cold plate 42, extending the service life of the entire heat dissipation device, and improving the stability and reliability of the heat dissipation system.

[0041] Reference Figure 4As shown, the dust cover 513 in this embodiment has a dust-filtering protective mesh 514 inside. The protective mesh 514 has a dense mesh structure. When air carrying dust enters the air inlet 511 of the outer cover 51 through the dust cover 513, fine dust particles are intercepted by the mesh of the protective mesh 514, while air can pass through smoothly. This effectively reduces the amount of fine dust entering the interior of the outer cover 51, preventing fine dust from accumulating on components such as the cooling fan 5 and the microchannel cold plate 42, thereby better ensuring the normal operation of each component of the heat dissipation device and improving the overall performance and service life of the heat dissipation system.

[0042] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
