Description

Technical Field

[0001] This utility model relates to the technical field of spectrometers, and in particular to an online spectrometer with multi-channel spectra. Background Technology

[0002] When traditional online spectrometers operate continuously for extended periods, the LED panel and optical components generate a significant amount of heat. Existing heat dissipation solutions often employ passive cooling or simple fan cooling, which suffers from low heat dissipation efficiency, internal circulation of hot air leading to "secondary heating," and easy dust intrusion affecting optical accuracy. These issues severely restrict the equipment's operational stability and measurement accuracy.

[0003] These defects are particularly prominent in industrial environments, causing equipment to frequently experience wavelength drift and light intensity attenuation due to overheating. This not only affects the reliability of test results but also significantly shortens the equipment's lifespan. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an online spectrometer with multi-channel spectroscopy, so as to solve the technical problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] An online spectrometer with multi-channel spectroscopy includes:

[0007] Housing, LED light panel, light guide assembly, and heat dissipation assembly;

[0008] One end of the outer casing is provided with a ventilation hole, and a heat dissipation component connected to the ventilation hole is installed inside;

[0009] The other end of the housing is provided with a fiber optic guide hole for connecting optical fibers;

[0010] The LED light panel is located inside the housing and corresponds to the heat dissipation component. Its light-emitting surface is fixedly connected to the light guide component through a bracket, and the bottom end of the bracket is fixedly connected to the bottom end of the housing.

[0011] Furthermore, the heat dissipation component includes:

[0012] The cooling fan is bolted to the inside of the ventilation hole. A heat-conducting fin is provided on one side of the cooling fan. The heat-conducting fin is an integrated frame structure and is fitted onto the back of the LED light panel. Thermally conductive material is filled between the heat-conducting fin and the back of the LED light panel.

[0013] Furthermore, air ducts are provided on both sides of the heat-conducting fins, with the top of the air ducts extending upwards through the outer shell, and the top of the two air ducts are jointly provided with an exhaust assembly.

[0014] Furthermore, the light guide component includes:

[0015] Multichannel spectral tubes and light guides;

[0016] The multi-channel spectral tube is tapered, with its large-diameter end fixed to the bracket by bolts, and its small-diameter end connected to the fiber optic guide hole by connecting tubes, with the axes on the same straight line.

[0017] The light guide plate is positioned directly in front of the LED light panel's emitting surface and is fixedly installed inside the bracket, aligned with the large-diameter end of the multi-channel spectral tube.

[0018] Furthermore, the exhaust assembly includes:

[0019] The top shell is fixedly connected to the upper openings of two air ducts on both sides of its bottom end. Two air duct fans are installed at the top of the top shell to exhaust the air inside the top shell.

[0020] Furthermore, a heat-conducting plate is provided on the opposite side of the two air ducts. The heat-conducting plate has mounting holes for installing light guide components, and the mounting holes are matched with the multi-channel spectral tube.

[0021] In summary, this utility model has at least one of the following beneficial technical effects:

[0022] 1. This online spectrometer with multi-channel spectroscopy uses air ducts as airflow guiding channels, which are respectively set on both sides of the heat-conducting fins. Its unique feature is that it can guide the hot airflow passing through the heat-conducting fins to the exhaust component at the top in an orderly manner, which can significantly improve the heat dissipation efficiency. In addition, the air ducts form a closed airflow channel, which eliminates the problem of hot air circulating and accumulating inside the equipment. This not only avoids the phenomenon of "secondary heating", but also effectively prevents external dust from entering the equipment through the heat dissipation channel, which significantly improves the adaptability and reliability of the equipment in complex industrial environments.

[0023] 2. This online spectrometer with multi-channel spectroscopy features hot air delivered by two air ducts that converges inside the top shell.

Detailed Implementation

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] Example:

[0032] Reference Figure 1 - Figure 4 The present invention discloses an online spectrometer with multi-channel spectroscopy, comprising:

[0033] 1. Housing; 2. LED light board; 3. Light guide assembly; and 4. Heat dissipation assembly.

[0034] One end of the outer casing 1 is provided with a ventilation hole 5, and a heat dissipation component 4 communicating with the ventilation hole 5 is provided inside;

[0035] The other end of the outer casing 1 is provided with an optical fiber guide hole 6 for connecting optical fibers;

[0036] The LED light panel 2 is located inside the housing 1, corresponding to the heat dissipation component 4. Its light-emitting surface is fixedly connected to the light guide component 3 through the bracket 7. The bottom end of the bracket 7 is fixedly connected to the bottom end inside the housing 1.

[0037] In this embodiment, when the optical system is working, the LED light board 2 and the light guide component 3 will continuously generate a large amount of heat. If this heat is not dissipated in time, it will lead to overheating, wavelength drift, or even damage to the device. To change this situation, the following technical solution is proposed in this embodiment to achieve efficient cooling:

[0038] Firstly, the LED light panel 2 serves as the main heat source, and the heat it generates is quickly captured by the integrated heat-conducting fins 42 tightly fitted on the back side. The heat-conducting material filling the space between the heat-conducting fins 42 and the LED light panel 2 ensures that the heat can be conducted to the fin array with extremely low loss.

[0039] Meanwhile, the heat generated by the light guide component 3 during operation is absorbed by the heat-conducting plate 44 arranged around it. The mounting holes 45 inside the heat-conducting plate 44 are tightly connected with the multi-channel spectral tube 31 to ensure effective heat transfer.

[0040] By setting the cooling fan 41, cooled external air is drawn in from the ventilation hole 5 at one end of the housing 1. The airflow blows across the surface of the heat-conducting fins, carrying away the heat on the fins. The heat-conducting fins 42 guide the flowing air to both sides, allowing the air to enter the interior of the air duct 43 and exhaust the air from the housing 1. Since the heat-conducting plate 44 is connected to the air duct 43, the airflow inside the air duct 43 can carry away the heat on the heat-conducting plate 44, thus achieving the purpose of cooling and heat dissipation for the LED main heat source and the light guide component 3.

[0041] The airflow carrying heat enters the air duct 43 and is transported upward to the exhaust assembly 8 at the top. The hot air is actively discharged from the equipment by the air guide fan 82 at the top of the exhaust assembly 8, realizing the circulation and discharge of heat during equipment operation. The airflow trajectory is a closed design, which effectively prevents the hot air from circulating and accumulating in the chassis, avoids secondary heating, and prevents dust from flowing back through the exhaust port, thus enhancing the environmental adaptability and reliability of the equipment.

[0042] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the heat dissipation component 4 includes:

[0043] The cooling fan 41 is installed inside the ventilation hole 5 by bolts. A heat-conducting fin 42 is provided on one side of the cooling fan 41. The heat-conducting fin 42 is an integrated frame structure and is sleeved on the back side of the LED light panel 2. The space between the heat-conducting fin 42 and the back side of the LED light panel 2 is filled with heat-conducting material.

[0044] In this embodiment, after the cooling fan 41 is started, it draws in cooling air from the ventilation hole 5 to form a directional airflow. At the same time, the large amount of heat generated by the LED light board 2 during operation is quickly captured by the heat-conducting fins 42 on its back side. The heat-conducting fins 42 adopt an integrated frame structure and are seamlessly attached to the back side of the LED light board 2 through the filling heat-conducting material, establishing an efficient heat conduction path. When the airflow passes over the surface of the heat-conducting fins 42, the accumulated heat is instantly carried away by forced convection. The integrated frame structure provides a larger heat dissipation surface area. Combined with forced air cooling, the heat dissipation efficiency is significantly improved, ensuring that the LED light board 2 operates at the optimal temperature, avoiding wavelength drift and light decay problems caused by overheating, and extending the service life of the light board 2.

[0045] In a further preferred embodiment of this utility model, such as Figure 4 As shown, air ducts 43 are provided on both sides of the heat-conducting fins 42, and the top of the air ducts 43 extends upward through the outer shell 1. The top of the two air ducts 43 are provided with an exhaust assembly 8.

[0046] In this embodiment, the air duct 43 serves as an airflow guiding channel and is respectively disposed on both sides of the heat-conducting fins 42. Its unique feature is that it can guide the hot airflow passing through the heat-conducting fins 42 in an orderly manner to the exhaust assembly 8 at the top. More importantly, through the physical connection with the heat-conducting plate 44, the air duct 43 can also simultaneously carry away the heat absorbed by the heat-conducting plate 44 when the airflow passes through. Furthermore, the air duct 43 constructs a closed airflow channel, eliminating the problem of hot air circulating and accumulating inside the equipment. This not only avoids the phenomenon of "secondary heating" but also effectively prevents external dust from entering the equipment through the heat dissipation channel, significantly improving the adaptability and reliability of the equipment in complex industrial environments.

[0047] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the light guide component 3 includes:

[0048] Multichannel spectral tube 31 and light guide plate 32;

[0049] The multi-channel spectral tube 31 is tapered, and its large-diameter end is fixedly connected to the bracket 7 by bolts, while its small-diameter end is connected to the fiber optic guide hole 6 by connecting pipes, and the axes are located on the same straight line.

[0050] The light guide plate 32 is positioned directly in front of the light-emitting surface of the LED light panel 2 and is fixedly installed inside the bracket 7, aligned with the large-diameter end of the multi-channel spectral tube 31.

[0051] In this embodiment, the light guide assembly 3 consists of a light guide sheet 32 ​​and a multi-channel spectral tube 31. The light guide sheet 32 ​​is located in front of the LED light panel 2 and is responsible for homogenizing the original light emitted by the LED, eliminating hot spots and speckles, and ensuring uniform light distribution. The homogenized light enters the conical multi-channel spectral tube 31. The spectral tube efficiently focuses and transmits the light to the output end through its special conical structure. The conical multi-channel spectral tube 31 design realizes efficient light collection and transmission, greatly improving the light energy utilization rate.

[0052] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the exhaust assembly 8 includes:

[0053] The top shell 81 is fixedly connected to the upper openings of two air ducts 43 on both sides of its bottom end. Two air duct fans 82 are provided at the top of the top shell 81 to exhaust the air inside the top shell 81.

[0054] In this embodiment, the exhaust assembly 8 serves as the terminal of the heat dissipation system, consisting of a top shell 81 and an air guide fan 82. The hot air delivered by the two air guide ducts 43 gathers inside the top shell 81, and the active exhaust of the air guide fan 82 creates a stable negative pressure environment inside the equipment, which significantly enhances the airflow dynamics of the entire heat dissipation system. The air collection chamber design of the top shell 81 balances the airflow pressure of the air guide ducts 43 on both sides, ensuring the stable operation of the heat dissipation system.

[0055] In a further preferred embodiment of this utility model, such as Figure 4 As shown, a heat-conducting plate 44 is provided on one side of the two air ducts 43 facing each other. The heat-conducting plate 44 has a mounting hole 45 for installing the light guide component 3, and the mounting hole 45 cooperates with the multi-channel spectral tube 31.

[0056] In this embodiment, the mounting hole 45 is precisely machined inside the heat-conducting plate 44, and its size is closely matched with the shape of the multi-channel spectral tube 31, ensuring that the heat-conducting plate 44 and the spectral tube achieve the maximum contact area and establish an efficient heat conduction interface, so that the heat generated by the light guide component 3 during operation can be quickly conducted to the heat-conducting plate 44 and then carried away by the airflow flowing through the air duct 43.

[0057] The implementation principle of the above embodiment is as follows: When the system is working, the heat generated by the LED light board 2 is quickly captured by the integrated heat-conducting fins 42 that are tightly attached to its back side, while the heat generated by the light guide component 3 during operation is effectively absorbed by the heat-conducting plate 44 that is arranged around it; the cooling fan 41 draws in cooling air from the ventilation hole 5, and the airflow carries away the main heat when it flows over the surface of the heat-conducting fins 42, and carries away the heat of the auxiliary heat source through the air duct 43 connected to the heat-conducting plate 44; finally, all the airflow carrying heat flows in an orderly manner in the air duct 43 and is discharged in a concentrated manner through the top exhaust component 8, forming a fully enclosed and highly efficient heat dissipation cycle.

[0058] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
