Description

Technical Field

[0001] This invention relates to the field of science education tools, specifically to an intelligent interconnected water chiller that integrates a laser. Background Technology

[0002] With the rapid development of laser technology, laser equipment is being used more and more widely in industrial manufacturing, materials processing, and medical fields. Among these applications, the laser itself, as the core component of laser equipment, has a crucial impact on the overall performance of the equipment due to its performance stability and lifespan. However, lasers generate a significant amount of heat during operation; if this heat is not dissipated effectively and promptly, it will severely affect the laser's performance stability and lifespan.

[0003] Traditional laser cooling methods typically employ either air cooling or water cooling. While air cooling is simple and easy to implement, its cooling efficiency is relatively low, making it difficult to meet the cooling requirements of high-power lasers. On the other hand, although water cooling offers higher cooling efficiency, it usually requires connecting the laser to an external water chiller via piping, which increases both system complexity and maintenance costs.

[0004] Furthermore, traditional laser cooling systems typically focus only on heat dissipation efficiency, neglecting the impact of ambient temperature and humidity on laser performance. In practical applications, ambient temperature and humidity are crucial factors affecting laser performance stability. Excessively high or low ambient temperatures and humidity can lead to decreased laser performance or even damage. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent interconnected water chiller with an integrated laser to address the deficiencies mentioned in the background section.

[0006] To achieve the above objectives, an intelligent interconnected water chiller integrating a laser is provided. The intelligent interconnected water chiller integrating a laser comprises:

[0008] A drawer-type laser generator is integrated into the cabinet space of the main body of the water chiller;

[0009] The water circulation system includes at least two low-temperature circulating water paths and one high-temperature circulating water path. The two low-temperature circulating water paths are used to cool the drawer-type laser generator and the water-cooled air conditioner, respectively, while the one high-temperature circulating water path is used to provide cooling for the machine tool cutting head.

[0010] The water-cooled air conditioner utilizes a low-temperature circulating water path in the water circulation system to achieve temperature control and dehumidification of the cabinet space.

[0011] A fan cooling system is installed inside the main body of the water chiller to assist in heat dissipation;

[0012] The central integrated control system is integrated into the main body of the water chiller and is intelligently interconnected with the water circulation system, water-cooled air conditioner, fan cooling system and drawer-type laser generator. It is used to monitor the working environment of the device and centrally schedule and control the water circulation system, water-cooled air conditioner and fan cooling system.

[0013] Furthermore, the central integrated control system supports RS485 communication and OPC UA standard network protocol, opens up internal monitoring data and control interfaces, and enables interconnection with the CNC system of the laser cutting machine. Through built-in sensors, it monitors ambient temperature and humidity in real time, adjusts water temperature according to season and time of day with adaptive algorithms, and adopts vibration and laser installation chamber water immersion detection technology.

[0014] Furthermore, the central integrated control system integrates intelligent temperature and humidity control functions, which automatically adjust in real time through an adaptive algorithm that employs a polynomial chaotic expansion model.

[0015] Furthermore, the polynomial chaotic expansion model is a probabilistic statistical method that maps the model output onto orthogonal random polynomial basis functions of random inputs, i.e. in, Let be an input to a random event in the space of possible outcomes; Let be a set of independent standard Gaussian random variables, corresponding to formula 1.1. and ; This is a set of multidimensional Hermitian polynomials, corresponding to formula 1.1. , usually referred to Uniform chaos; For deterministic constants, corresponding to formula 1.1 ; Obtain the general expression for a multidimensional Hermitian polynomial, i.e. in, For the reason A set of Gaussian random variables A random vector formed;

[0016] Equation (1.1) can also be expressed as in, respectively with One-to-one correspondence; the orthogonality of chaotic polynomials can be expressed as in, The Kronecker sign function; based on computational requirements, the polynomial chaotic expansion model requires truncation to... in, The coefficients of the truncated expansion depend on the dimension of the random variable. and the order of polynomial expansion , It can be represented as Equation (1.5) above is used to calculate the coefficients of the truncated polynomial chaotic expansion model. A truncation criterion is required to converge the optimization process; its error value must meet a threshold, which is defined as follows: in, It is an error The threshold is initially set to To achieve good convergence, the coefficient values ​​need to be calculated in each iteration of the optimization process.

[0017] Furthermore, the drawer-type laser generator is designed to be pluggable, allowing for replacement or maintenance of the laser generator without shutting down the entire water-cooled system.

[0018] Furthermore, the central integrated control system includes a detection module for monitoring the laser power, wavelength, and spot quality parameters of the laser, and can automatically adjust the working status of the water circulation system and the fan cooling system based on these parameters.

[0019] Furthermore, the water circulation system includes a multifunctional sensor for detecting water flow, water temperature, and water quality, and can automatically filter, heat, or cool the circulating water based on the detected data to ensure the stable operation of the drawer-type laser generator.

[0020] Furthermore, the fan cooling system includes multiple fans with adjustable speed and direction, which can automatically adjust the fan operating parameters according to the operating temperature of the laser generator and the ambient temperature to achieve a cooling effect.

[0021] Furthermore, the water-cooled air conditioner also includes sensors for detecting temperature and humidity inside the cabinet, as well as a control module that automatically adjusts the air conditioner's operating status based on the data from these sensors, ensuring that the environment inside the cabinet is maintained in the state required by the laser generator.

[0022] Furthermore, the high and low temperature water interface in the water circulation system is at least two low temperature circulating water paths and one high temperature circulating water path. The two low temperature circulating water paths are transported through the internal pipelines of the device, while the high temperature circulating water will be output through the external interface. At the same time, the main body of the water chiller is provided with a water inlet, an optical fiber outlet, and a high temperature water interface for the high and low temperature water interfaces.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] A separate, enclosed cabinet space is created between the fan cooling system and the water circulation system to house the drawer-type laser generator. This saves floor space compared to conventional layouts. The low-temperature circulating water circuit, originally located externally, is now located inside the water chiller, minimizing the length of the circulating water pipes, improving cooling efficiency, and extending the laser's lifespan. Additionally, a separate low-temperature water circuit is designed to work in conjunction with a water-cooled air conditioning system, adding an air conditioner to the cabinet housing the drawer-type laser generator for temperature control and dehumidification. The entire unit features a central integrated control system that monitors the operating environment and centrally manages the fan cooling system, water circulation system, and air conditioning system to achieve safety and energy efficiency. Furthermore, adhering to standard network communication protocols and fieldbus technology, the unit's internal data and control interfaces are open to enable intelligent interconnection with machine tools.

[0029] Please see Figure 1-3 This invention provides a technical solution: an intelligent interconnected water chiller integrating a laser, comprising:

[0030] Water chiller main body 1: Provides an independent and enclosed cabinet space to protect the internal equipment from the influence of the external environment, while ensuring that the equipment does not affect each other.

[0031] Drawer-type laser generator 4: The laser generator is integrated within the cabinet space to produce high-energy laser beams. During operation, the laser generator generates a large amount of heat, requiring an effective cooling system to maintain its stable operation.

[0032] Water circulation system 5: The system includes at least two low-temperature circulating water paths and one high-temperature circulating water path; Low-temperature circulating water path: The two low-temperature circulating water paths are used to cool the drawer-type laser generator 4 and the water-cooled air conditioner 3 respectively; The low-temperature circulating water absorbs heat to reduce the temperature of the laser generator and the cabinet space; High-temperature circulating water path: One high-temperature circulating water path is used to provide cooling for the machine tool cutting head to ensure that the machine tool will not be damaged by overheating during the cutting process.

[0033] Water-cooled air conditioner 3: It operates by using one low-temperature circulating water path in the water circulation system 5; it lowers the temperature of the cabinet space and controls the humidity through low-temperature circulating water, providing a suitable working environment for the laser generator and other equipment.

[0034] Fan cooling system 6: Located inside the main body 1 of the water chiller, it is used to assist in heat dissipation. When the cooling effect of the water circulation system is insufficient to meet the heat dissipation requirements, the fan cooling system will be activated to carry away the heat through airflow, further reducing the temperature of the cabinet space.

[0035] Central Integrated Control System 2: Integrated into the main body 1 of the water chiller, it is the core of the intelligent interconnected water chiller; it is intelligently interconnected with the water circulation system 5, water-cooled air conditioner 3, fan cooling system 6, and drawer-type laser generator 4; it monitors parameters such as ambient temperature, humidity, water flow, and water temperature in real time through built-in sensors; based on the monitoring data, it centrally schedules and controls the working status of the water circulation system 5, water-cooled air conditioner 3, and fan cooling system 6 to ensure that the laser generator and other equipment operate in the best working environment.

[0036] The central integrated control system supports RS485 communication and OPC UA standard network protocol, opening up internal monitoring data and control interfaces. Based on the priorities set by the integrator, it interconnects with the CNC system of the laser cutting machine and supports other intelligent integration solutions. Through built-in sensors, it monitors ambient temperature and humidity in real time, and uses adaptive algorithms to adjust water temperature according to season and time of day, improving laser output stability and lifespan. Simultaneously, it reduces energy consumption of the pressurized water circulation system, achieving energy conservation and emission reduction. Its unique vibration detection technology for the water-cooled unit and water immersion detection technology for the laser installation chamber enhances laser safety and lifespan.

[0037] The central integrated control system 2 integrates intelligent temperature and humidity control functions, and automatically adjusts them in real time through an adaptive algorithm, which adopts a polynomial chaotic expansion model.

[0038] The polynomial chaotic expansion model is a probabilistic and statistical method that maps the model output onto orthogonal random polynomial basis functions of random inputs. in, Let be an input to a random event in the space of possible outcomes; Let be a set of independent standard Gaussian random variables, corresponding to formula 1.1. and ; This is a set of multidimensional Hermitian polynomials, corresponding to formula 1.1. , usually referred to Uniform chaos; For deterministic constants, corresponding to formula 1.1 ; Obtain the general expression for a multidimensional Hermitian polynomial, i.e. in, For the reason A set of Gaussian random variables A random vector formed;

[0039] Equation (1.1) can also be expressed as in, respectively with One-to-one correspondence; the orthogonality of chaotic polynomials can be expressed as in, The Kronecker sign function; based on computational requirements, the polynomial chaotic expansion model requires truncation to... in, The coefficients of the truncated expansion depend on the dimension of the random variable. and the order of polynomial expansion , It can be represented as Equation (1.5) above is used to calculate the coefficients of the truncated polynomial chaotic expansion model. A truncation criterion is required to converge the optimization process; its error value must meet a threshold, which is defined as follows: in, It is an error The threshold is initially set to To ensure good convergence, coefficient values ​​need to be calculated in each iteration of the optimization process. After the algorithm model is built, all relevant data fed back from the water chiller is continuously uploaded through the smart gateway. Abnormal data is analyzed and the algorithm model is further adjusted and optimized to confirm that the final controlled temperature and humidity fully meet the working requirements of the laser generator.

[0040] In addition, it is necessary to integrate vibration and water immersion sensors inside the laser cavity to monitor in real time whether there is water leakage or abnormal vibration inside the cavity, stop the machine in time, and support fault reporting function to avoid more serious damage.

[0041] The drawer-type laser generator 4 is designed to be pluggable, allowing for replacement or maintenance of the laser generator without shutting down the entire water-cooled system.

[0042] The drawer-type laser generator 4 generates a large amount of heat during operation, which is initially dissipated through the internal cooling system. Two low-temperature circulating water paths flow through the laser generator 4 and the water-cooled air conditioner 3 respectively, absorbing heat and returning to the cooling section of the water circulation system for further cooling. The cooled low-temperature circulating water is then reused to ensure that the laser generator 4 and the water-cooled air conditioner 3 always operate at a low temperature. The drawer-type laser generator 4 is designed to be pluggable, allowing it to be easily pulled out or inserted into the water chiller body 1. The laser generator can be easily replaced or maintained without shutting down the entire water chiller system. After replacement or maintenance, the new or repaired laser generator is inserted into the water chiller body 1, and the system can continue to operate normally.

[0043] The central integrated control system 2 includes a detection module for monitoring laser power, wavelength, and spot quality parameters to assess the laser's operating status. Based on these parameters, it automatically adjusts the operating status of the water circulation system 5 and the fan cooling system 6. According to the laser's operating status parameters obtained by the detection module, the central integrated control system 2 intelligently determines the laser's cooling requirements. If the laser's cooling requirements increase, the system automatically increases the flow rate of low-temperature circulating water in the water circulation system 5 to lower the laser generator's temperature. Simultaneously, the operating status of the fan cooling system 6 is adjusted accordingly to provide more effective auxiliary cooling.

[0044] The water circulation system 5 includes a multi-functional sensor for detecting water flow, water temperature and water quality, and can automatically filter, heat or cool the circulating water based on the detected data to ensure the stable operation of the drawer-type laser generator 4.

[0045] The fan cooling system 6 includes multiple fans with adjustable speed and direction, which can automatically adjust the operating parameters of the fans according to the operating temperature of the laser generator and the ambient temperature to achieve the cooling effect.

[0046] The water-cooled air conditioner 3 also includes sensors for detecting temperature and humidity inside the cabinet, as well as a control module that automatically adjusts the air conditioner's operating status based on the data from these sensors, ensuring that the environment inside the cabinet is maintained in the state required by the laser generator.

[0047] The high and low temperature water interface 9 in the water circulation system 5 is at least two low temperature circulating water paths and one high temperature circulating water path. The two low temperature circulating water paths are transported through the internal pipeline of the device, while the high temperature circulating water will be output through the external interface 10. At the same time, the water chiller body 1 is equipped with a water inlet 8, an optical fiber outlet 7 and a high temperature water interface of the high and low temperature water interface 9 on the outside of the shell, which greatly reduces the number of external cables.

[0048] The water inlet 8 is located outside the housing of the water chiller body 1 and is used to supply cooling water to the water circulation system 5. The location and size of the water inlet are reasonably designed to facilitate connection with the water source and ensure that the cooling water can smoothly enter the water circulation system.

[0049] The fiber optic outlet 7 is also located outside the housing of the water chiller body 1 and is used for the fiber optic connection of the laser. The location and fixing method of the fiber optic outlet ensures a stable connection of the laser and reliable signal transmission.

[0050] The high-temperature water interface of the high-low temperature water interface 9 is located outside the housing of the water chiller body 1 and is connected to the external interface 10. It is used to output high-temperature circulating water. The temperature, flow rate and pressure of the high-temperature circulating water are precisely controlled to ensure effective cooling and stable operation of the machine tool cutting head.
