Description

Technical Field

[0001] This invention relates to the field of drug catalysis technology, and more specifically to a drug catalysis device. Background Technology

[0002] Photochemical reaction technology is widely used in drug synthesis, material modification, and fine chemicals. Its reaction efficiency and selectivity depend on the light intensity stability of the light source and the temperature control of the reaction system. In continuous flow photochemical devices, to obtain sufficient light intensity and ensure controllable reactions, the light source typically needs to operate continuously at high power. High-power light sources generate a large amount of heat during emission. If this heat cannot be dissipated effectively and promptly, it will cause the light source's operating temperature to rise, leading to light intensity attenuation, spectral drift, or even light source failure, severely affecting the stability and reproducibility of the photochemical reaction. Therefore, providing efficient and reliable heat dissipation for the light source is one of the key technologies for continuous flow photochemical equipment.

[0003] However, existing photochemical devices primarily employ water-cooling structures to cool the light source. This is achieved by incorporating coolant channels within the light source body, allowing the circulating coolant to remove heat. While water cooling effectively reduces the light source temperature, the continuous photochemical reaction system also includes transparent reaction tubing arranged around the light source. This tubing also generates significant heat upon absorbing light energy, leading to a rise in the reaction liquid temperature. Relying solely on water cooling of the light source cannot control the temperature of the reaction tubing, resulting in an uneven thermal field throughout the reaction system. This can cause fluctuations in reaction conditions, unstable conversion rates, or an increase in side reactions.

[0004] Therefore, existing photochemical drug catalysis devices still have shortcomings in overall thermal management, making it difficult to ensure that continuous photochemical reactions can be carried out under stable and efficient temperature and light intensity conditions. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a drug catalysis device that solves the technical problem of insufficient overall thermal management in existing photochemical drug catalysis devices.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This invention provides a drug catalysis device, comprising: a shell having a working chamber inside; a heat dissipation body disposed within the working chamber, the heat dissipation body having an axially formed air duct, and the heat dissipation body separating the air duct from the working chamber, and multiple liquid cooling pipes embedded within the heat dissipation body; a light source plate attached to the surface of the heat dissipation body facing away from the air duct; an air guide base disposed at the bottom of the heat dissipation body, the base having an air guide cavity connecting the air duct and the working chamber; a centrifugal fan installed at the air guide base for introducing airflow into the air duct; and a drug liquid pipe arranged within the working chamber, surrounding the light source plate, with a gap forming between the drug liquid pipe and the light source plate.

[0007] In some embodiments, the air guide base has multiple air guide ports, which connect the air guide cavity and the working cavity, and are evenly arranged around the light source panel.

[0008] In some embodiments, the drug catalytic device further includes a quartz cover disposed on one side of the air vent to isolate the working chamber from the light source panel.

[0009] In some embodiments, a sealing ring is provided at the connection between the quartz cover and the air guide base to seal and isolate the light source plate and the working chamber.

[0010] In some embodiments, the centrifugal fan further includes an air guide duct, which passes through the air guide base and extends axially along the air duct direction; a water collection tank and a drain outlet are provided on the side of the housing near the air guide base for discharging condensate inside the air duct.

[0011] In some embodiments, the drug catalytic device further includes a hood structure disposed at the top of the working chamber for guiding the exhaust airflow and blocking light leakage.

[0012] In some embodiments, the hood structure includes shielding members arranged at intervals along the axial direction of the heat dissipation body, the shielding members covering the top of the working cavity, and the shielding members having openings near the housing or the heat dissipation body to guide airflow out.

[0013] In some embodiments, the drug catalytic device further includes clamping guide rods, which are arranged in pairs in the working chamber and extend along the axial direction of the heat dissipation body for clamping and fixing the drug liquid tube.

[0014] In some embodiments, the drug catalytic device further includes a fixing ring plate, which is disposed on the top of the heat dissipation body and has an air outlet and a positioning hole. The air outlet is used to discharge airflow, and the positioning hole is used to insert a clamping guide rod.

[0015] In some embodiments, the drug catalytic device further includes a water-cooled radiator, which is connected to a liquid cooling pipe via an external pipeline, and the airflow generated by the centrifugal fan is cooled by the water-cooled radiator before entering the air duct.

[0016] Compared with existing technologies, the drug catalysis device provided by this invention achieves dual cooling of the light source and the drug solution tube by constructing a heat dissipation system that combines water cooling and air cooling. This application incorporates liquid-cooled pipes inside the heat dissipation body, allowing the main heat from the back of the light source to be rapidly conducted away through the coolant, fundamentally improving the heat dissipation efficiency of the light source. Simultaneously, airflow from a fan is introduced into the air duct and acts on the outside of the heat dissipation body, forming a stable air-cooling channel. This enhances the heat dissipation of the light source while effectively cooling the outer wall of the drug solution tube surrounding the light source, thereby suppressing the temperature rise of the reaction liquid due to light absorption. Through the combined use of efficient water cooling and forced air convection, this application not only significantly reduces the operating temperature of the light source, making the light intensity more stable and its lifespan longer, but also makes the light-receiving environment of the drug solution tube more stable during the reaction process, making the reaction temperature more controllable and avoiding uneven reaction or increased side reactions caused by temperature fluctuations.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] To address the shortcomings in overall thermal management of existing photochemical drug catalysis devices, this invention provides a drug catalysis device capable of achieving efficient heat dissipation for the light source and the drug solution tube 60.

[0021] It should be noted that the drug catalytic device described in this invention is used for, but not limited to, photochemical drug catalysis. For ease of explanation, this invention will only use the application of the drug catalytic device in photochemical drug catalysis as an example. The principle of the drug catalytic device applied to other types of equipment is essentially the same as that applied to photochemical drug catalysis, and will not be described in detail here.

[0022] Please see Figures 1 to 3 , Figure 1 This is an overall schematic diagram of a drug catalytic device provided in an embodiment of the present invention. Figure 2 This is a side view of a drug catalytic device provided in an embodiment of the present invention. Figure 3 This is provided by the embodiments of the present invention. Figure 2 A cross-sectional view along the AA direction. The drug catalysis device includes a housing 10, a heat dissipation body 20, a light source plate 30, an air guide base 40, a centrifugal fan 50, and a drug liquid pipe 60. It aims to solve the problems of insufficient heat dissipation of the light source and difficulty in controlling the temperature of the reaction pipeline in existing photochemical drug catalysis equipment, thereby achieving a more stable and efficient photochemical catalytic reaction process.

[0023] The housing 10 forms an external support structure, and its interior defines a working cavity 11 for accommodating various functional components. A heat dissipation body 20 is arranged axially within the working cavity 11. An axially extending air duct 21 is provided inside the heat dissipation body 20. The structure of the heat dissipation body 20 effectively isolates the air duct 21 from the working cavity 11, allowing airflow to form an independent and controlled guiding path within the air duct 21. Furthermore, please refer to... Figure 4 , Figure 4 This is provided by the embodiments of the present invention. Figure 2 A cross-sectional view along the BB direction. Multiple liquid cooling pipes 22 are prefabricated inside the heat dissipation body 20. The liquid cooling pipes 22 are connected to the external coolant circulation system to supply circulating coolant to the heat dissipation body 20, so as to remove the heat generated by the light source during operation, thereby achieving efficient water cooling of the light source components.

[0024] The light source panel 30 is fixedly attached to the surface of the heat dissipation body 20 away from the air duct 21, so that the panel can face the working chamber 11 to emit illumination energy. At the same time, the back side is in close contact with the heat dissipation body 20 to achieve good heat conduction. The heat generated by the operation of the panel is quickly conducted away by the liquid cooling pipes 22 inside the heat dissipation body 20. In order to further improve the airflow organization and heat exchange efficiency, the air guide base 40 is set below the heat dissipation body 20. The base has an air guide cavity 41, which is connected to the air duct 21 of the heat dissipation body 20 and is connected to the airflow area of ​​the working chamber 11. This allows the airflow sent by the fan to enter the air guide cavity 41 through the air duct 21 and then flow upward along the circumference of the light source.

[0025] A centrifugal fan 50 is installed at the air guide base 40. By starting the fan, external air is drawn in and delivered at high pressure into the air duct 21, causing the cooling airflow to flow upwards along the air duct 21 and enter the working chamber 11, providing air cooling to the liquid medicine pipes 60 arranged around the heat dissipation body 20. The liquid medicine pipes 60 are located within the working chamber 11, arranged in a spiral or circumferential manner around the light source plate 30, ensuring uniform irradiation of the reaction liquid within the illumination area. A gap is provided between the liquid medicine pipes 60 and the light source plate 30, allowing the cooling airflow to flow fully within the gap area, further enhancing the cooling effect of the reaction pipeline and preventing the reaction liquid from overheating due to light energy absorption.

[0026] In this embodiment, a synergistic heat dissipation system combining water cooling and air cooling is constructed. By arranging liquid-cooled pipes 22 within the heat dissipation body 20, circulating coolant directly removes the main heat generated during the light source's operation, resulting in significant and rapid thermal conduction cooling of the back of the light source. Simultaneously, a centrifugal fan 50 directs airflow into the air duct 21, acting on the heat dissipation body 20 to form a stable cooling airflow field, further enhancing the heat dissipation effect. Utilizing the efficient thermal conductivity of water cooling and the forced convection capability of air cooling, the heat dissipation body 20 consistently provides efficient heat dissipation during the operation of the light source, significantly improving overall heat dissipation efficiency and reducing the temperature rise of the light source. Simultaneously, as the air-cooled airflow rises in the working chamber 11, it cools the outer wall of the surrounding drug solution pipes 60, controlling the temperature rise of the reaction liquid caused by illumination. Therefore, this solution not only simultaneously improves the heat dissipation capacity of the light source but also achieves synchronous temperature control of the drug solution pipes 60, effectively improving the overall thermal management performance of the photochemical catalysis device and making the photochemical reaction environment more stable.

[0027] In one embodiment, please refer to Figure 4 and Figure 5 , Figure 4 This is provided by the embodiments of the present invention. Figure 2 Cross-sectional view along the BB direction. Figure 5 This is provided by the embodiments of the present invention. Figure 3A magnified view of a portion of area A. The air guide base 40 is equipped with multiple air guide ports 42 for guiding airflow into the working chamber 11. Each air guide port 42 is connected to an air guide cavity 41 inside the air guide base 40, allowing airflow from the air duct 21 into the air guide cavity 41 to enter the working chamber 11 through multiple channels. To achieve a more uniform distribution of cooling airflow upon entering the working chamber 11, the multiple air guide ports 42 are spaced apart along the circumferential direction of the light source panel 30 and are evenly distributed in a ring around the light source panel 30. This arrangement not only avoids uneven cooling caused by airflow concentration in one direction but also allows cooling airflow to simultaneously flow into the working chamber 11 from multiple directions.

[0028] After the airflow enters the working chamber 11, each air guide 42 forms multiple independent air inlet paths in the circumferential direction, causing the air entering the working chamber 11 to form a surrounding cooling airflow band around the light source plate 30, making the air cooling heat dissipation more uniform and avoiding heat dissipation deviation caused by unilateral air cooling. Subsequently, the airflow flows upward along the gap between the light source plate 30 and the liquid tube 60, gradually converging to form an overall rising cooling airflow field, cooling the light source and the liquid tube 60.

[0029] In this embodiment, the surrounding airflow structure introduces airflow from multiple directions to form a continuous and stable circulating layer, further enhancing the heat dissipation capacity of the light source and the liquid tube 60. Simultaneously, the uniform distribution of the air vents 42 ensures good uniformity of the airflow entering the working chamber 11, helping to stabilize the heat exchange conditions between the light source and the liquid tube 60, thereby making temperature control more reliable.

[0030] In one embodiment, please refer to Figure 3 , Figure 3 This is provided by the embodiments of the present invention. Figure 2 A cross-sectional view along the AA direction. The drug catalysis device also includes a quartz cover 31 for protecting the light source plate 30 and improving heat dissipation reliability. The quartz cover 31 is positioned between the drug liquid pipe 60 and the light source plate 30, located on one side of the air vent 42, covering the outer surface of the light source plate 30, so that the light source plate 30 is completely in an independent and enclosed light source cavity, thereby directly isolating the airflow in the working cavity 11 from the light source plate 30. As a material with high light transmittance, high temperature resistance and good chemical stability, the quartz cover 31 allows light energy to be smoothly transmitted to the drug liquid pipe 60, and can withstand large temperature differences without deformation or failure.

[0031] Because the air-cooling system of this device continuously supplies outside air to the working chamber 11 during operation, the airflow temperature is usually lower than the actual operating temperature of the light source board 30. This humid, cold air easily forms condensation on the surface of the light source board 30, potentially leading to short circuits, damp solder joints, and corrosion. In this embodiment, a sealed connection is established between the quartz cover 31 and the air guide base 40, preventing the airflow in the working chamber 11 from directly contacting the light source board 30. This places the light source board 30 in a relatively enclosed area without direct airflow, allowing the heat from the light source board 30 to be primarily dissipated through the heat dissipation body 20 on its back and the internal liquid cooling pipes 22. This fundamentally avoids the direct impact of humid, cold airflow on the board surface. This structural design provides a more stable heat dissipation environment for the light source board 30, preventing condensation formation and reducing temperature fluctuations on the surface caused by airflow disturbances. This significantly improves the stability of the light source's intensity and its operational reliability.

[0032] Further, please refer to Figure 5 , Figure 5 This is provided by the embodiments of the present invention. Figure 3 A partial enlarged view of area A in the middle. In some embodiments, a sealing ring 43 is provided at the connection position between the quartz cover 31 and the air guide base 40. The sealing ring 43 is used to circumferentially seal the connection area between the opening 72 end of the quartz cover 31 and the air guide base 40, structurally sealing the light source cavity where the light source lamp board 30 is located, so that the light source cavity is completely isolated from the external working cavity 11. By setting the sealing ring 43, the airflow will not seep into the interior of the quartz cover 31 after the air guide base 40 enters the working cavity 11, thereby ensuring that the cooling airflow in the working cavity 11 always flows on the outside of the quartz cover 31, while the cavity where the light source lamp board 30 is located maintains a stable environment that is static and free from airflow interference.

[0033] In addition, the sealing ring 43 forms a reliable sealing interface between the quartz cover 31 and the air guide base 40, which can absorb minor tolerance errors at the connection, improve the installation stability of the quartz cover 31, and prevent loosening and air leakage caused by vibration or thermal expansion and contraction during long-term operation.

[0034] This sealed structure allows the light source panel 30 to remain in a dry working environment for extended periods, reducing the risk of electrical short circuits, pad corrosion, or optical component contamination caused by moisture, effectively improving the reliability and lifespan of the light source system. Simultaneously, this sealed design also helps maintain the cleanliness of the light source cavity, resulting in more stable light source output and further enhancing the overall reaction stability of the photochemical catalytic device.

[0035] In one embodiment, please refer to Figure 3 and Figure 6 , Figure 3 This is provided by the embodiments of the present invention. Figure 2Cross-sectional view along the AA direction. Figure 6 This is a partial structural schematic diagram of a drug catalytic device provided in an embodiment of the present invention. The centrifugal fan 50 also includes a guide duct 51 for extending the airflow path. The guide duct 51 passes through the guide base 40 and extends axially along the air duct 21 of the heat dissipation body 20, allowing the airflow output by the fan to directly enter the top of the air duct 21. To prevent condensate retention in the air duct 21, this embodiment provides a water collection tank 13 and a drain outlet 14 connected to the water collection tank 13 on the side of the housing 10 near the guide base 40. The water tank collects condensate falling from the air duct 21, while the drain outlet 14 discharges the collected condensate to the outside of the device, thereby ensuring that the inside of the air duct 21 remains dry and preventing condensate from affecting the lower structure or electrical components of the fan.

[0036] In this embodiment, the air duct 51 extends into the air duct 21. The extended air duct 51 guides the airflow output by the fan to the upper region of the air duct 21, so that the airflow rises along the direction of the air duct 51 to the top of the air duct 21 after entering the air duct 21. Since the top of the air duct 21 is closed, the airflow cannot continue to flow upward after reaching the top, so it flows downward along the inner wall of the air duct 21 and enters the air guide cavity 41. During this reciprocating flow process, the condensate formed on the inner wall of the air duct 21 is washed away by the airflow and carried away from the wall surface, and then slides down the air duct 21 into the water collection tank 13 on the housing 10, and finally discharged through the drain outlet 14, realizing the automatic cleaning of the condensate in the air duct 21.

[0037] Secondly, by extending the airflow path within the air duct 21, the airflow can fully contact the inner wall of the heat dissipation body 20 over a longer transmission distance, thereby achieving a more efficient heat exchange effect. This extended path structure can significantly improve the air-cooling efficiency, ensuring that the airflow passing through the air duct 21 fully absorbs the heat from the outside of the heat dissipation body 20 before entering the working chamber 11, further enhancing the air-cooling effect of the light source.

[0038] In some embodiments, please refer to Figure 3 , Figure 3 This is provided by the embodiments of the present invention. Figure 2 A cross-sectional view along the AA direction. The drug catalysis device also includes a hood structure 70 disposed on the top of the working chamber 11. The hood structure 70 covers the upper outlet area of ​​the working chamber 11 and is used to collect, guide, and organize the exhaust airflow rising from inside the working chamber 11, so that the airflow can be smoothly discharged to the outside of the device along a predetermined path. At the same time, the hood structure 70 forms an effective shielding area around the airflow passage, which can block the high-intensity light emitted by the light source panel 30 from diffusing to the outside of the device along the exhaust path, thereby avoiding leakage or interference from ultraviolet light or other strong light to the surrounding environment and improving the safety of device operation.

[0039] The hood structure 70, connected to the top opening 72 of the working chamber 11, forms the final channel for airflow discharge, allowing the airflow after heat exchange with the light source and the liquid pipe 60 to concentrate and enter the interior of the hood. The inner cavity of the hood provides a relatively enclosed guiding space for the airflow, preventing turbulence or backflow at the outlet and maintaining the stability of the exhaust direction. In some embodiments, the inlet or interior of the hood structure 70 may have a tapered, expanded, or reversible guiding area to improve the uniformity of airflow discharge. However, the function of the hood structure 70 is not dependent on a specific shape; its core purpose is to ensure smooth airflow discharge and effective light shielding.

[0040] Furthermore, in some embodiments, the hood structure 70 includes a plurality of shielding members 71 spaced apart along the axial direction of the heat dissipation body 20. The shielding members 71 are disposed in the top region of the working cavity 11 and cover the above region in a layered or segmented manner, so that a shielding channel composed of multiple shielding members 71 is formed above the light source lamp panel 30, thereby effectively suppressing light leakage from the exhaust path while maintaining unobstructed ventilation.

[0041] Each shielding member 71 has an opening 72 on either the side near the housing 10 or the side near the heat dissipation body 20 for guiding airflow. The opening 72 communicates with the working chamber 11, allowing the airflow flowing upward along the working chamber 11 to pass sequentially through the gaps between the shielding members 71. As the airflow passes through the openings 72 of the shielding members 71 step by step, the flow direction of the gas is organized and guided by the shielding members 71, making the discharged airflow tend to be stable. At the same time, because a staggered light-shielding path is formed between the shielding members 71, the light emitted by the light source cannot directly leak out along the airflow channel, thereby enhancing the light shielding capability of the entire device.

[0042] In this embodiment, the relative misalignment or spacing between the shielding members 71 forms a multi-stage guiding region, which gradually reduces turbulence or impact as the exhaust airflow passes through each stage of opening 72, thereby improving exhaust efficiency. This structure not only achieves light blocking but also makes the exhaust path more uniform and stable, which is beneficial for maintaining the continuous heat exchange capacity of the air-cooled system.

[0043] In one embodiment, please refer to Figure 3 and Figure 7 , Figure 3 This is provided by the embodiments of the present invention. Figure 2 Cross-sectional view along the AA direction. Figure 7This is a partially exploded schematic diagram of a drug catalytic device according to an embodiment of the present invention. The drug catalytic device also includes clamping guide rods 12 for fixing the reaction pipeline (i.e., the drug solution pipe 60). The clamping guide rods 12 are arranged in pairs in the working chamber 11 and extend along the axial direction of the heat dissipation body 20, so that the two guide rods form a stable and continuous support structure in the axial direction. A clamping space for accommodating the drug solution pipe 60 is formed between each pair of clamping guide rods 12. The drug solution pipe 60 can be pressed into or embedded in the clamping space by a slight external force during assembly, thereby achieving reliable positioning and clamping of the drug solution pipe 60.

[0044] Because the clamping guide rod 12 extends axially along the heat dissipation body 20, its length can cover the main arrangement area of ​​the liquid tube 60 in the working chamber 11, ensuring that the liquid tube 60 maintains good straightness and tightness during long-distance installation, and preventing the liquid tube 60 from shifting, warping, or loosening due to light exposure, heat, or airflow disturbance. Simultaneously, the clamping guide rods 12 are arranged in pairs on both sides of the liquid tube 60, providing a uniform clamping force, allowing the liquid tube 60 to stably surround the light source plate 30, improving the positioning accuracy of the liquid tube 60 relative to the light source, thereby ensuring a uniform light path for the reaction liquid within the illuminated area.

[0045] Furthermore, multiple pairs of clamping guide rods 12 can be spaced upwards around the working chamber 11, allowing the liquid tubes 60 to be segmented and positioned in multiple directions, further improving the neatness and stability of the pipeline arrangement. This structure enables the liquid tubes 60 to be arranged around the outer periphery of the light source in a single layer, close fit, and regular manner, which is beneficial for the cooling airflow to form a uniform flow path on the outer surface of the liquid tubes 60, thereby enhancing the air cooling effect. At the same time, the clamping guide rods 12 can also avoid the light-blocking problem caused by the liquid tubes 60 squeezing or overlapping each other, ensuring the overall photochemical reaction efficiency of the device.

[0046] Furthermore, in some embodiments, the drug catalytic device further includes a fixing ring plate 80 for co-positioning the drug solution tube 60 and the upper exhaust path of the tissue. The fixing ring plate 80 is disposed in the top region of the heat dissipation body 20, and is connected or fixedly connected to the upper end of the heat dissipation body 20, so that the fixing ring plate 80 forms a functional structural platform above the working chamber 11. The fixing ring plate 80 has several air outlet holes 81 and positioning holes 82 circumferentially formed on it. The air outlet 81 is connected to the airflow channel in the working chamber 11, and is used to smoothly discharge the cooling airflow flowing upward along the working chamber 11 to the air cap structure 70 or the external environment; the positioning hole 82 is used to pass through the clamping guide rod 12, so that the clamping guide rod 12 is stably limited and supported on the fixed ring plate 80.

[0047] In this embodiment, by providing positioning holes 82 on the fixed ring plate 80, the upper end of the clamping guide rod 12 can be inserted and positioned with the fixed ring plate 80, so that the axial position of each guide rod in space is accurately maintained, thereby ensuring the structural stability of the clamping guide rods 12 arranged in pairs and extending along the axial direction of the heat dissipation body 20. The fixed ring plate 80, as the upper support point of the guide rod, can effectively prevent the guide rod from shifting due to airflow impact or device vibration during long-distance arrangement, so that the liquid tube 60 always maintains a regular and tight winding form during operation, which is conducive to maintaining the consistency of the light-receiving path of the liquid tube 60 and the continuity of the air-cooling path.

[0048] Furthermore, the air outlets 81 on the fixed ring plate 80 are arranged along the outer periphery of the light source plate 30, so that the airflow entering the working chamber 11 can be orderly discharged through the air outlets 81 of the fixed ring plate 80 after passing through the heat exchange area of ​​the light source plate 30 and the liquid pipe 60. The number and distribution of the air outlets 81 can be adjusted according to the heat dissipation requirements, so that the discharged airflow is evenly distributed in the circumferential direction. This not only avoids local airflow stagnation from affecting the heat dissipation effect, but also allows the cooling airflow to be fully diffused before being discharged, promoting the overall stability of the air-cooling system.

[0049] In one embodiment, the drug catalytic device further includes a water-cooled radiator 90, which is connected to a liquid cooling pipe via an external pipeline, and the airflow generated by the centrifugal fan 50 is cooled by the water-cooled radiator 90 before entering the air duct 21.

[0050] In one embodiment, the drug catalysis device further includes a water-cooled radiator 90 for providing a cold source to the liquid cooling system. The water-cooled radiator 90 is connected to the liquid cooling pipes inside the heat dissipation body 20 via external piping, so that the water-cooled radiator 90 and the liquid cooling pipes together form a closed coolant circulation loop. The water-cooled radiator 90 can cool the returning coolant, keeping it at a low temperature before entering the liquid cooling pipes, thereby improving the heat exchange capacity of the liquid cooling pipes when dissipating heat from the light source lamp panel 30, and allowing the high heat on the back of the light source to be carried away more quickly.

[0051] In addition to serving as the cold source for the liquid cooling circuit, the water-cooled radiator 90 further collaborates with the air-cooling system. In this embodiment, the airflow generated by the centrifugal fan 50 passes through the heat exchange area of ​​the water-cooled radiator 90 before entering the air duct 21, pre-cooling the airflow temperature before it enters the air duct 21. In this way, the temperature of the air used by the air-cooling system is reduced in the initial stage, thereby providing a stronger temperature difference drive when it subsequently flows through the air duct 21, the outside of the light source, and the periphery of the liquid pipe 60, improving the overall air-cooling efficiency.

[0052] In this embodiment, the water-cooled radiator 90 not only cools the circulating coolant but also cools the airflow entering the air duct 21, enabling water cooling and air cooling to work together at the source. This effectively improves the water cooling efficiency at the back of the light source and the air cooling intensity in the working cavity 11, allowing the light source to maintain a stable operating temperature even when operating at high power, further enhancing the stability and reliability of the photochemical reaction process.

[0053] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
