Description

Technical Field

[0001] This utility model relates to the field of chlorination reaction technology, and in particular to a light source structure and a chlorination reaction device. Background Technology

[0002] In today's technological development, light sources are used extensively, covering a wide range of fields from everyday lighting to industrial production and scientific research. As the performance requirements for light sources continue to increase, issues such as heat dissipation and light distribution are becoming increasingly prominent.

[0003] Taking the preparation process of ethylene chloride carbonate, an important electrolyte additive in lithium battery production, as an example, the stable operation of the light source plays a decisive role in the preparation of ethylene chloride carbonate by initiating a chlorination reaction using chlorine gas and ethylene carbonate as raw materials and ultraviolet light. Ethylene chloride carbonate has excellent properties and can not only be used as a lithium battery additive, but also as a necessary intermediate in the synthesis of vinylene carbonate and ethylene chloride carbonate, and it also plays an intermediate role in many fine chemical synthesis processes.

[0004] However, existing light sources on the market suffer from severe heat dissipation problems during prolonged use. Current cooling methods, such as lamp jacket heat exchange and jacketed tube heat exchange, have limited effectiveness and cannot meet the demands for efficient heat dissipation. This not only leads to unstable operation of the light source but also significantly shortens the lifespan of the light source equipment, thereby affecting production efficiency and product quality. Furthermore, in many applications requiring high uniformity of illumination, such as precision inspection lighting and chlorine light sources, existing light sources struggle to achieve uniform light distribution, resulting in numerous blind spots and failing to meet practical requirements.

[0005] Based on this, a novel light source structure and chlorination reaction device were developed in this invention to solve the above problems. Utility Model Content

[0006] One objective of this invention is to provide a light source structure in which the cooling water circuit is directly located inside the light source carrier. This allows for the rapid and effective absorption and removal of heat transferred from the light source components through the circuit board and substrate, greatly improving heat dissipation efficiency and preventing light decay, performance degradation, or even damage to the light source components due to overheating. This, in turn, extends the service life of the light source structure.

[0007] The present invention adopts the following technical solution: a light source structure, the light source structure including a light source carrier, the light source carrier being in the shape of a polygonal column, and having a cooling water channel formed inside;

[0008] Each outer surface of the light source carrier is equipped with a substrate, and a circuit board is mounted on the side of the substrate away from the cooling water channel; a light source component is mounted on the circuit board.

[0009] Further, the substrate is provided with a groove structure away from the side of the cooling water channel, and the groove structure is filled with heat-conducting silica gel.

[0010] Further, the substrate is an aluminum alloy substrate.

[0011] Further, the light source member is a lamp bead.

[0012] Further, the cooling water channel comprises a water inlet pipe located at the center of the light source carrier and a plurality of mutually independent water outlet pipes circumferentially surrounding the outside of the water inlet pipe; the water inlets of the water outlet pipes are respectively communicated with the water outlets of the water inlet pipe.

[0013] Further, the light source carrier is uniformly divided into a plurality of mutually independent carrier units along the circumferential direction thereof, and the water outlet pipes are formed in each carrier unit.

[0014] Further, a vacuum heat insulation layer is arranged between the water inlet pipe and the water outlet pipe.

[0015] Further, the water inlets of the water outlet pipes and the water outlets of the water inlet pipe are located at one end of the light source carrier, and the water outlets of the water outlet pipes and the water inlets of the water inlet pipe are located at the other end of the light source carrier.

[0016] Further, a quick connector is arranged at the water inlet of the water inlet pipe.

[0017] Compared with the related art, the present application has the following advantages:

[0018] The working principle of the light source structure is as follows: the circuit board provides power supply and circuit control for the light source member, so that the light source member can emit light and realize the lighting function. However, the light source member generates a large amount of heat during work, and the heat is rapidly transmitted to the circuit board in close contact with the light source member. Since the circuit board has a certain heat conductivity, the heat is diffused on the circuit board. Then, part of the heat is consumed and taken away by the substrate, and the other part of the heat is conducted to the light source carrier through the substrate. At this time, the cooling water channel in the light source carrier starts to work, and the cooling liquid (such as water) circulates in the cooling water channel, and the cooling liquid continuously absorbs the heat conducted from the substrate and takes the heat away from the light source carrier in the circulation process, so as to realize efficient heat dissipation and ensure that the temperature of each component of the light source structure is maintained in a reasonable range.

[0019] Therefore, the cooling water path is directly arranged inside the light source carrier, which can quickly and effectively absorb and take away the heat transferred from the light source member through the circuit board and the substrate. Compared with the traditional natural heat dissipation or simple air-cooled heat dissipation mode, the liquid cooling mode greatly improves the heat dissipation efficiency, avoids the light decay, performance decline or even damage of the light source member due to overheating, and prolongs the service life of the light source structure.

[0020] Meanwhile, the whole light source structure adopts a modular design, and the light source carrier, the substrate, the circuit board and the light source member are relatively independent. In the installation process, each component can be assembled respectively, which reduces the installation difficulty and improves the production efficiency. When a component fails, it is also convenient to disassemble and replace, for example, only the corresponding circuit board needs to be removed from the substrate, and the damaged light source member can be replaced, without the need to disassemble the whole light source structure, thereby reducing the maintenance cost and time cost.

[0021] In addition, the polygonal column-shaped light source carrier enables the light source member to be distributed on multiple side surfaces to emit light from different angles, which is beneficial to realize more uniform light distribution and reduce light dead angles, and meets various application scenarios with high requirements on uniformity of illumination light.

[0022] Another purpose of the utility model is to provide a chlorination reaction device, the chlorination reaction device includes above-mentioned light source structure. BRIEF DESCRIPTION OF DRAWINGS

[0027] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] The following is in conjunction with the appendix Figs. 1-2 The present invention will be described in detail with specific embodiments:

[0029] like Figs. 1-2 As shown, this utility model provides a light source structure, which includes a light source carrier 1. The light source carrier 1 is in the shape of a polygonal prism, providing a solid and stable support frame for the entire light source structure. Simultaneously, a cooling water channel 2 is formed inside the light source carrier 1 for heat dissipation, ensuring that the light source operates in a stable temperature environment. In this embodiment, the light source carrier 1 is octagonal prism-shaped, providing uniform light from eight sides.

[0030] Each outer surface of the light source carrier 1 is equipped with a substrate 3, and a circuit board 4 is mounted on the side of the substrate 3 away from the cooling water channel 2; a light source element 5 is mounted on the circuit board 4. In this embodiment, the light source element 5 is an LED. Due to the high luminous efficiency of LEDs, their energy consumption is much lower than that of traditional lighting sources while achieving the same lighting effect, thus saving a significant amount of energy costs. At the same time, LEDs typically have a long lifespan, reaching tens of thousands of hours or even longer, which greatly reduces the frequency of light source replacement during use, reducing maintenance costs and the inconvenience caused by light source replacement.

[0031] The general working principle of the light source structure in this invention is as follows: Circuit board 4 provides power and circuit control for the light source component 5, enabling it to emit light and achieve the lighting function. However, the light source component 5 generates a large amount of heat during operation, which is rapidly transferred to the circuit board 4 in close contact with it. Due to the thermal conductivity of circuit board 4, the heat diffuses across it. Subsequently, some of the heat is consumed and carried away by substrate 3, while the remaining heat is conducted to the light source carrier 1 through substrate 3. At this time, the cooling water channel 2 inside the light source carrier 1 begins to function. Coolant (such as water) circulates in the cooling water channel 2, continuously absorbing the heat conducted from substrate 3 and carrying it away from the light source carrier 1 during the circulation process, achieving efficient heat dissipation and ensuring that the temperature of each component of the light source structure is maintained within a reasonable range.

[0032] Therefore, the cooling water path 2 is directly arranged inside the light source carrier 1, which can quickly and effectively absorb and take away the heat transferred from the light source 5 through the circuit board 4 and the base plate 3. Compared with the traditional natural heat dissipation or simple air-cooled heat dissipation mode, the liquid cooling mode greatly improves the heat dissipation efficiency, avoids the light decay, performance degradation or even damage of the light source 5 caused by overheating, and prolongs the service life of the light source structure.

[0033] At the same time, the whole light source structure adopts a modular design, and the light source carrier 1, the base plate 3, the circuit board 4 and the light source 5 are relatively independent. During installation, each component can be assembled separately, which reduces the installation difficulty and improves the production efficiency. When a component fails, it is also convenient to disassemble and replace, for example, only the corresponding circuit board 4 needs to be removed from the base plate 3, and the damaged light source 5 can be replaced without the need to disassemble the whole light source structure, which reduces the maintenance cost and time cost.

[0034] In addition, the polygonal column-shaped light source carrier 1 allows the light source 5 to be distributed on multiple sides to emit light from different angles, which is conducive to achieving more uniform light distribution and reducing light dead angles, and meets various application scenarios with high requirements for uniformity of illumination light.

[0035] Further, in some specific embodiments, the base plate 3 is provided with a groove structure 30 on the side away from the cooling water path 2, and the groove structure 30 is filled with heat-conducting silica gel 6. By filling the groove structure 30 with heat-conducting silica gel 6, the heat dissipation capacity of the base plate 3 is strengthened. The good heat-conducting performance allows the heat to be quickly conducted away from the base plate 3, avoiding the accumulation of heat on the light source 5, the base plate 3 and the circuit board 4, effectively reducing the working temperature of the light source 5 and the circuit board 4, helping to maintain the stable performance of the light source 5, reduce the problems such as light decay and shortened service life caused by overheating, and further prolong the overall service life of the light source structure.

[0036] In the embodiment, the base plate 3 is an aluminum alloy base plate. Aluminum alloy has good heat conductivity, which can quickly conduct the heat generated by the light source 5 during operation, and cooperates with the heat-conducting silica gel 6 to greatly improve the heat dissipation efficiency, help to maintain the stable working temperature of the light source structure, and reduce the problems such as performance degradation and shortened service life caused by overheating. At the same time, aluminum alloy has high strength and hardness, which can provide reliable support for the circuit board 4 and the light source 5, improve the stability and reliability of the whole light source structure. In addition, the price of aluminum alloy is relatively low, which can effectively control the material cost and reduce the production cost of the product under the premise of ensuring the performance of the light source structure.

[0037] Further, in some embodiments, the cooling water path 2 includes a water inlet pipe 20 located at the center of the light source carrier 1, and a plurality of water outlet pipes 21 which are independently arranged around the water inlet pipe 20; the water inlet of each water outlet pipe 21 is in communication with the water outlet of the water inlet pipe 20. In this embodiment, the light source carrier 1 is evenly divided into a plurality of carrier units 10 along the circumferential direction, and the water outlet pipe 21 is formed in each carrier unit 10, so that each unit can be cooled independently.

[0038] In operation, the cooling liquid enters the water inlet pipe 20, and then flows into the water outlet pipes 21 which are independently arranged around the water inlet pipe 20. The water outlet pipes 21 are distributed at different positions of the light source carrier 1, and the cooling liquid can absorb more heat from the light source carrier 1 when flowing in the water outlet pipes 21. The cooling liquid which has completed heat exchange flows out of the water outlet pipes 21, and then returns to the cooling device through an external circulation system to be cooled, and then re-enters the water inlet pipe 20, so as to realize continuous cooling of the light source carrier 1.

[0039] As can be seen from the above, the plurality of water outlet pipes 21 are independently arranged around the cooling water path 2, so that the cooling liquid can contact the light source carrier 1 more comprehensively, the heat dissipation area is increased, and the heat dissipation efficiency is effectively improved. Compared with a single cooling pipe, this design can quickly remove the heat of the light source carrier 1, avoid local overheating, and ensure that the light source 5 and the circuit board 4 are always at an appropriate working temperature.

[0040] At the same time, the cooling liquid is distributed from the central water inlet pipe 20 to each water outlet pipe 21, which ensures the uniformity of cooling of each part of the light source carrier 1, so that the temperature distribution of the light source carrier 1 is more uniform, which helps to maintain the light stability of the light source 5, reduces the problem of inconsistent light decay caused by temperature difference, and prolongs the overall service life of the light source.

[0041] In addition, the water outlet pipes 21 are independent of each other, so that when one of the water outlet pipes 21 fails (such as blockage, damage, etc.), it will not affect the normal work of other water outlet pipes 21, and maintenance personnel can repair or replace the failed pipe alone, which reduces the maintenance difficulty and cost, and improves the maintainability of the entire light source structure.

[0042] Further, in some specific embodiments, a vacuum insulation layer 7 is arranged between the water inlet pipe 20 and the water outlet pipe 21. The cooling liquid in the water inlet pipe 20 has a lower temperature, while the cooling liquid in the water outlet pipe 21 has a higher temperature after absorbing the heat of the light source carrier 1. The vacuum insulation layer 7 can effectively prevent heat conduction between the water inlet pipe 20 and the water outlet pipe 21, avoid the low-temperature water inlet being heated by the high-temperature water outlet, and ensure that the cooling liquid can maintain a lower temperature before entering the light source carrier 1, thereby improving the cooling efficiency and enabling the cooling system to more effectively remove the heat generated by the light source.

[0043] Further, in some more specific embodiments, the water inlet of the water outlet pipe 21 and the water outlet of the water inlet pipe 20 are located at one end of the light source carrier 1, and the water outlet of the water outlet pipe 21 and the water inlet of the water inlet pipe 20 are located at the other end of the light source carrier 1, so that the cooling liquid forms a U-shaped cooling loop in the water inlet pipe 20 and the water outlet pipe 21. The U-shaped cooling loop makes the flow path of the cooling liquid in the light source carrier 1 longer, and the contact time of the cooling liquid with the light source carrier 1 increases. This means that the cooling liquid has more time to absorb the heat generated by the light source, and can more fully exchange heat, thereby more effectively reducing the temperature of the light source carrier 1, improving the cooling effect, and helping to maintain the high performance and stability of the light source. At the same time, the longer flow path enables the cooling liquid to better promote the diffusion of heat in the light source carrier 1 during the flow process. When the cooling liquid flows in the U-shaped loop, it drives the surrounding heat to be evenly distributed, avoiding the accumulation of heat in a local area, making the temperature distribution of the light source carrier 1 more uniform, and further improving the uniformity and effect of cooling.

[0044] Further, a quick connector is arranged at the water inlet of the water inlet pipe 20. The quick connector can realize quick connection between the water inlet pipe 20 and an external cooling liquid supply device, without the need for using complex tools and tedious installation steps, greatly saving installation time and improving work efficiency. In the present embodiment, the quick connector has a size of a quarter interface, which is highly versatile.

[0045] The utility model discloses a light source structure on the basis of the above, still provides a chlorination reaction device, the chlorination reaction device includes above-mentioned light source structure. Because the chlorination reaction device at least contains all the technical schemes of the light source structure, at least has all the advantages of the light source structure, here no longer elaborates.

[0046] The above describes the utility model with the help of specific embodiments, but it should be understood that the specific description here should not be understood as limiting the essence and scope of the utility model, and various modifications of the above embodiments made by ordinary skilled persons in the art after reading the specification all belong to the scope protected by the utility model.
