[0001] The utility model relates to the technical field of photochemical reactions, in particular to a photocatalytic glass plate type microreactor with an integrated light source and a heat dissipation unit thereof. Background Art

[0002] A photochemical microreactor is a miniature chemical reactor that combines microfluidics technology with the principles of photochemical reactions. It achieves precise control of chemical reactions by illuminating reactants within microchannels with a light source. It offers the following advantages: First, it is highly controllable, enabling precise regulation of reaction rates and progression; second, it is highly efficient, as its miniaturization increases the contact area between the reactants and the light source; third, it is highly reproducible, with high precision and consistency, enabling large-scale production of samples under identical conditions; and fourth, it is easy to operate, compact, and capable of completing reactions in a short time. Currently, photochemical microreactors are widely used in fields such as chemistry, biology, and medicine, including drug synthesis, organic synthesis, photochemical analysis, and biosensors.

[0003] Currently, there are many different types and styles of photocatalytic glass microreactors on the market, but they generally use a design that separates the light source from the glass reaction plate. This design makes the device inconvenient to disassemble and assemble, requiring users to disassemble and assemble the light source and reaction plate separately for each use or maintenance, which increases the complexity of operation. Moreover, since the light source and reaction plate are separated, the overall size of the device is large, which takes up laboratory space. At the same time, this separate design makes the operation and use process less simple, which may affect the efficiency and accuracy of the experiment. Utility Model Content

[0013] Preferably, a cooling fan is fixedly provided on the outside of the light board, and reactive light sources of different wavelengths are provided inside the light board.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the present invention provides a photocatalytic glass plate microreactor with an integrated light source and a heat dissipation unit, which has the following beneficial effects:

[0016] 1. A photocatalytic glass plate microreactor with an integrated light source and its heat dissipation unit is used in conjunction with a glass plate reactor structure and a jacketed heat dissipation plate structure. The reactor consists of two glass plate reactors and a jacketed heat dissipation plate in the middle. A jacketed heat dissipation plate is fixed between the two glass plate reactors. This sandwich design reduces the thickness of the entire device. At the same time, the light board is directly installed on both sides of the jacketed heat dissipation plate and fixed by a fixing clip. This design eliminates additional supporting structures and space, so that the light source and the reaction channel can fit tightly. The base and mounting groove enable the light board to be tightly fixed on both sides of the heat dissipation plate without the need for additional brackets or support devices, which further reduces the overall volume of the equipment. The compact structural design can also optimize the heat dissipation path. At the same time, it integrates multiple types of light source heat dissipation methods, and different implementation plans can be selected according to the reaction heat conditions and the light source heat conditions.

[0017] 2. A photocatalytic glass plate microreactor with an integrated light source and its heat dissipation unit is used in conjunction with a light plate structure and a glass plate reactor structure. The light plates in the reactor are installed on both sides of the reactor and directly irradiate the reaction channel. This close design reduces the propagation distance of light in the air or other media, thereby reducing light loss. At the same time, reaction light sources of different wavelengths are provided in the light plate, and the most suitable wavelength can be selected according to the needs of the reaction liquid, thereby improving the utilization efficiency of light. The spoiler baffles are not connected to the reaction channel, but their direction is inclined to the flow direction of the liquid in the reaction channel, which can evenly distribute the temperature in the reaction channel and improve the reaction efficiency. Moreover, the reaction heat exchange medium channel and the heat dissipation module in the jacketed heat dissipation plate can effectively control the temperature in the reactor and keep the reaction liquid within a suitable temperature range for reaction.

[0018] 3. The photocatalytic glass plate microreactor with an integrated light source and its heat dissipation unit is used in conjunction with a reaction channel structure and a reaction heat exchange medium channel structure. When a low-temperature heat exchange medium is introduced into the reaction heat exchange medium channel, the low-temperature heat exchange medium will reduce the temperature of the air in the through hole at the center of the spoiler column. The temperature reduction will cause the gas density to increase, thereby changing the pressure in the area. This pressure difference will cause the surrounding hotter air to flow to the low-temperature area to achieve pressure balance. The air flow speed on both sides of the jacketed heat dissipation plate is accelerated, thereby improving the heat transfer from the fluid in the reaction channel to the heat exchange medium. At the same time, since a spoiler baffle is provided in the reaction channel, the reaction liquid will be affected by the spoiler baffle when passing through the reaction channel. The design of the spoiler baffle enables the heat to be more evenly distributed in the reaction channel. Even if the flow direction of the liquid in the reaction channel is inclined, the spoiler baffle can help eliminate the temperature gradient and avoid local overheating or overcooling. At the same time, the presence of the spoiler baffle can also produce a certain disturbance on the liquid flow, enhance the mixing effect of the liquid, and make the photocatalytic reaction more complete. This liquid disturbance can increase the contact opportunity between the reactants and the catalyst, and further improve the reaction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figure 1 、 Figure 2 、 Figure 5 A photocatalytic glass plate microreactor with an integrated light source and heat dissipation unit includes a glass plate reactor 1, wherein a reaction channel 11 is provided within the glass plate reactor 1. The reaction channel 11 is used for the flow of the reaction liquid and the occurrence of the photocatalytic reaction. This ensures the effective progress of the reaction and controls the reaction conditions. The glass plate reactor 1 is composed of two pieces, and a jacketed heat sink 2 is fixedly provided between the two glass plate reactors 1. The jacketed heat sink 2 can effectively control the temperature inside the reactor, preventing overheating or overcooling, thereby improving the reaction efficiency and stability. The heat sink can also provide structural support, making the entire device more stable. A base 3 is assembled at the bottom of the jacketed heat sink 2. The upper end surfaces of the base 3 on both sides of the jacketed heat sink 2 are provided with mounting grooves 31. The design of the base 3 and the mounting grooves 31 allows the light board 4 to be firmly mounted on both sides of the heat sink, thus ensuring the stability and position accuracy of the light source and ensuring that the liquid in the reaction channel 11 is evenly illuminated. The mounting grooves 31 are equipped with a light board 4 that generates the reaction light source. The light board 4 is directed toward the glass plate reactor 1 to illuminate the reaction light source. The light board 4 directly illuminates the reaction channel 11, which can reduce the propagation distance of light in the air or other media, thereby reducing light loss and improving light utilization efficiency.

[0032] The top of the jacket heat sink 2 is also equipped with a fixing clamp 5, which can firmly fix the lamp board 4 on both sides of the heat sink to prevent the lamp board 4 from shifting during operation, thereby ensuring the continuity and stability of the reaction. The fixing clamp 5 clamps and fixes the lamp board 4 on both sides of the jacket heat sink 2.

[0033] See also Figure 1 、 Figure 2 、 Figure 5 , Figure 8 The jacketed heat sink 2 is provided with a reaction heat exchange medium channel 21, which allows the passage of a cooling medium to regulate the reactor temperature. By controlling the temperature of the heat exchange medium, the reaction liquid in the reactor can be kept within a suitable temperature range, improving reaction efficiency and stability. The reaction heat exchange medium channel 21 is connected to a heat dissipation module 6, which is used to control the reactor temperature. The photocatalytic reaction typically releases heat, and excessively high temperatures can affect reaction efficiency and stability. The heat dissipation module 6 removes excess heat using the cooling medium, maintaining the reaction liquid within a suitable temperature range and thus improving reaction efficiency and stability. The heat dissipation module 6 is fixedly mounted on the top of the jacketed heat sink 2. Several spoiler columns 22 are also provided within the reaction heat exchange medium channel 21. These spoiler columns 22 enhance fluid convection, further improving heat exchange efficiency. Through convection, the cooling medium is more evenly distributed throughout the heat exchange channel, effectively removing heat generated during the reaction. The spoiler columns 22 have through-holes extending through both ends of the jacketed heat sink 2 and are not connected to the reaction heat exchange medium channel 21.

[0034] See also Figure 1 、 Figure 2 、 Figure 5 and Figure 9 The cross-section of the reaction channel 11 is in the shape of a U-shaped tube. This design can increase the residence time of the reaction liquid in the reaction channel 11, thereby ensuring that the reaction is fully carried out. The U-shaped tube shape can also optimize the angle of light illumination and improve the efficiency of light utilization. The glass plate reactor 1 is provided with a plurality of straight groove-shaped spoiler baffles 12. The provision of the spoiler baffles 12 helps to evenly distribute the temperature in the reaction channel 11 and avoid local overheating or supercooling. The spoiler baffles 12 can promote the disturbance of the liquid, so that the reactants and catalysts are in contact more fully, thereby improving the reaction efficiency. In addition, the design of the spoiler baffles 12 being inclined in the direction of the reaction channel 11 can eliminate the temperature gradient and ensure that the temperature in the entire reaction channel 11 is uniform. The spoiler baffles 12 are hollow plates. The spoiler baffles 12 are not connected to the reaction channel 11. The spoiler baffles 12 pass through the glass plate reactor 1. The through-design allows heat to be transferred more evenly. Through these spoiler baffles 12, heat can be quickly conducted from the glass plate to the reaction liquid, thereby eliminating the temperature gradient and avoiding local overheating or supercooling. The plurality of baffles 12 are arranged at an angle to the direction of liquid flow within the reaction channel 11. This design helps enhance the agitation of the liquid, allowing for better mixing of the liquid during flow. The inclined baffles 12 increase the contact area of the liquid, improving the efficiency of heat and mass transfer, and thus enhancing overall reaction efficiency.

[0035] See also Figure 1 、 Figure 2 、 Figure 5The fixing clip 5 and the mounting slot 31 are both provided with fixing holes, and the top and bottom of the lamp panel 4 are both provided with positioning holes, which match the fixing holes and are fixed by bolts. This design ensures the stability and accurate positioning of the lamp panel 4. Bolt fixation can prevent the lamp panel 4 from loosening or shifting during operation, ensuring that the light source always accurately illuminates the reaction channel 11, ensuring the efficiency and consistency of the photocatalytic reaction. The matching design of the positioning holes and the fixing holes makes the installation and removal of the lamp panel 4 simple and convenient, which is conducive to the maintenance and replacement of the light source of the equipment, and improves the operability and flexibility of the equipment. Please refer to Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 The heat dissipation module 6 uses a compressor refrigeration structure, a semiconductor refrigeration structure, or a coolant system. The heat dissipation requirements may vary under different reaction processes and environmental conditions. Compressor refrigeration, semiconductor refrigeration, and coolant systems each have their own advantages and disadvantages. The most suitable heat dissipation method can be selected according to the specific situation. Figure 10 A cooling fan 41 is fixedly provided on the outside of the lamp board 4, and the bottom of the cooling fan 41 is a cooling fin. The cooling fins can increase the heat exchange efficiency and heat exchange area of the cooling fan. The lamp board 4 will generate a lot of heat during operation, and the cooling fan 41 can quickly take away the heat to prevent the lamp board 4 from overheating, thereby extending the service life of the light source and maintaining a stable light output. Reaction light sources of different wavelengths are arranged in the lamp board 4. Photocatalytic reactions have specific requirements for light wavelengths, and different reactions may require light sources of different wavelengths. By arranging light sources of different wavelengths in the lamp board 4, the lighting conditions can be flexibly adjusted to meet the needs of different reactions and improve the utilization efficiency of light energy and the reaction efficiency.

[0036] Working principle: When using the utility model to react, the reaction liquid is introduced into the reaction channel 11, and the light panels 4 on both sides are activated. At the same time, the light panels 4 are adjusted to illuminate the light source with a wavelength corresponding to the reaction of the reaction liquid. At this time, the reaction liquid in the reaction channel 11 is irradiated and reacts. During the reaction, the heat dissipation module 6 on the top of the jacket heat dissipation plate 2 will start to cool the jacket heat dissipation plate 2, so that the reaction liquid in the reaction process maintains a suitable temperature. At the same time, the heat dissipation fan 41 installed on the light panel 4 will start to assist in heat dissipation. The heat dissipation module 6 is replaced to meet the temperature range required by different reactions. The reactor consists of two glass plate reactors 1 and a jacket heat dissipation plate 2 in the middle. A jacket heat dissipation plate 2 is fixedly arranged between the two glass plate reactors 1. This sandwich design reduces the thickness of the entire device. At the same time, the light panels 4 are directly mounted on both sides of the jacket heat dissipation plate 2 and fixed by fixing clamps 5. This design eliminates additional support structures and space, allowing the light source and reaction channel 11 to fit tightly. Furthermore, the base 3 and mounting slots 31 allow the light panel 4 to be tightly fixed to both sides of the heat sink without the need for additional brackets or supports, further reducing the overall size of the device. The compact design also optimizes the heat dissipation path and integrates multiple light source cooling methods, allowing different implementation options to be selected based on the heat generated by the reaction and light sources.

[0037] The lamp panels 4 in this reactor are installed on both sides of the reactor and directly illuminate the reaction channel 11. This close design reduces the propagation distance of light in the air or other media, thereby reducing light loss. At the same time, reaction light sources of different wavelengths are provided in the lamp panel 4, and the most suitable wavelength can be selected according to the needs of the reaction liquid, thereby improving the utilization efficiency of light. In addition, the spoiler baffles 12 are not connected to the reaction channel 11, but their direction is inclined to the direction of liquid flow in the reaction channel 11, which can evenly distribute the temperature in the reaction channel 11 and improve the reaction efficiency. Moreover, the reaction heat exchange medium channel 21 and the heat dissipation module 6 in the jacketed heat sink 2 can effectively control the temperature in the reactor and keep the reaction liquid reacting within a suitable temperature range.

[0038] When a low-temperature heat exchange medium is introduced into the reaction heat exchange medium channel 21, it lowers the temperature of the air in the central through-hole of the spoiler column 22. This temperature drop increases the gas density, causing the pressure in that area to change. This pressure difference forces the surrounding, warmer air to flow toward the lower-temperature area to achieve pressure equilibrium. This air flow is known as convection, which improves the efficiency of heat transfer. This convection increases the air flow rate within the jacketed heat sink 2, thereby increasing the efficiency of heat transfer from the fluid in the reaction channel 11 to the heat exchange medium. Furthermore, since the spoiler baffle 12 is provided within the reaction channel 11, the reaction liquid is affected by the spoiler baffle 12 as it passes through the reaction channel 11. The design of the spoiler baffle 12 ensures a more even distribution of heat within the reaction channel 11. Even if the liquid flow direction within the reaction channel 11 is tilted, the spoiler baffle 12 helps eliminate temperature gradients and prevent localized overheating or overcooling. Furthermore, the presence of the spoiler baffle 12 can create a certain disturbance in the liquid flow, enhancing the mixing effect and ensuring a more complete photocatalytic reaction. This liquid disturbance can increase the contact opportunity between reactants and catalysts, further improving reaction efficiency.
