Description

Technical Field

[0001] The invention relates to the field of popular science teaching aids, and in particular to an intelligent interconnected water cooling machine with an integrated laser. Background Art

[0002] With the rapid development of laser technology, laser equipment is increasingly used in industrial manufacturing, material processing, medical and other fields. Among them, the laser is the core component of the laser equipment, and its performance stability and service life have a vital impact on the overall performance of the laser equipment. However, the laser generates a lot of heat during operation. If the heat cannot be dissipated in a timely and effective manner, it will seriously affect the performance stability and service life of the laser.

[0003] Traditional laser cooling methods mostly use air cooling or water cooling. Among them, although the air cooling method is simple and easy, the heat dissipation efficiency is low and it is difficult to meet the heat dissipation requirements of high-power lasers; and although the water cooling method has a high heat dissipation efficiency, it usually requires the laser to be connected to an external water cooler through a pipeline, which not only increases the complexity of the system, but also increases the maintenance cost of the system.

[0004] In addition, traditional laser cooling systems usually only focus on the cooling effect, while ignoring the impact of ambient temperature and humidity on laser performance. In practical applications, ambient temperature and humidity are one of the important factors affecting the stability of laser performance. If the ambient temperature and humidity are too high or too low, the laser performance will be degraded or even damaged. Summary of the invention

[0005] The object of the present invention is to provide an intelligent interconnected water chiller with an integrated laser to solve the defects mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, an intelligent interconnected water-cooling machine with integrated laser is provided, and an intelligent interconnected water-cooling machine with integrated laser comprises:

[0007] The main body of the water-cooling machine has an independent and closed cabinet space inside;

[0008] A drawer-type laser generator, which is integrated in the cabinet space of the water-cooling machine body;

[0009] A water circulation system, comprising at least two low-temperature circulating water circuits and one high-temperature circulating water circuit, wherein the two low-temperature circulating water circuits are used to cool the drawer-type laser generator and the water-cooled air conditioner respectively, and the one high-temperature circulating water circuit is used to provide cooling for the cutting head of the machine tool;

[0010] A water-cooled air conditioner, which uses a low-temperature circulating water circuit in the water circulation system to achieve temperature control and dehumidification of the cabinet space;

[0011] A fan heat dissipation system, which is arranged in the water cooler body and is used to assist in heat dissipation;

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

[0013] Furthermore, the central control system supports RS485 communication and OPC UA standard network protocol, opens the internal monitoring data and control interface of the device, realizes interconnection with the laser cutting machine numerical control system, monitors the ambient temperature and humidity in real time through built-in sensors, adjusts the water temperature by season and time period with the adaptive algorithm, and uses vibration and laser installation chamber water immersion detection technology.

[0014] Furthermore, the central control system integrates the function of intelligently controlling temperature and humidity, and automatically makes real-time adjustments through an adaptive algorithm, which adopts a polynomial chaos expansion model.

[0015] Furthermore, the polynomial chaos expansion model is a probabilistic statistical method that maps the model output onto an orthogonal random polynomial basis function of random input, that is,

[0016]

[0017] Among them, θ is an input of a random event in the possible outcome space; is a set of independent standard Gaussian random variables; is a set of multidimensional Hermitian polynomials, usually called P-order uniform chaos; L, is a deterministic constant; obtain the general expression of multidimensional Hermitian polynomials, that is,

[0018]

[0019] Among them, ξ is a group of P Gaussian random variables The random vector is:

[0020]

[0021] Among them, b i and ψ i [ξ(θ)] and L, and One-to-one correspondence; the orthogonality of chaotic polynomials can be expressed as

[0022]

[0023] Among them, δ ij is the Kronecker sign function; according to the computational requirements, the polynomial chaos expansion model requires truncation to

[0024]

[0025] Among them, N P is the coefficient of the truncated expansion, whose value depends on the dimension d of the random variable and the order P, N of the polynomial expansion P It can be expressed as

[0026]

[0027] The above formula (1.5) is used to calculate the coefficients of the truncated polynomial chaos expansion model, and the truncation criterion is required to converge the optimization process. The error value must meet the threshold, which is defined as

[0028]

[0029] Among them, T L is the error ε L The threshold is initially set to T L =0.001% to have good convergence; therefore, the coefficient value needs to be calculated in each iteration during the optimization process.

[0030] Furthermore, the drawer-type laser generator is designed to be pluggable, allowing the laser generator to be replaced or maintained without shutting down the entire water chiller system.

[0031] Furthermore, the central integrated control system includes a detection module for monitoring the laser power, wavelength and spot quality parameters of the laser operating status, and can automatically adjust the working status of the water circulation system and the fan cooling system according to these parameters.

[0032] 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 according to the detected data to ensure the stable operation of the drawer-type laser generator.

[0033] Furthermore, the fan cooling system includes a plurality of fans with adjustable wind speed and wind direction, and can automatically adjust the operating parameters of the fans according to the operating temperature of the laser generator and the ambient temperature to achieve a cooling effect.

[0034] Furthermore, the water-cooled air conditioner also includes sensors for detecting the temperature and humidity inside the cabinet, and a control module for automatically adjusting the operating state of the air conditioner according to the sensor data, to ensure that the environment inside the cabinet is maintained at the state required by the laser generator.

[0035] Furthermore, the high and low temperature water interfaces in the water circulation system are at least two low temperature circulating water circuits and one high temperature circulating water circuit. The two low temperature circulating water circuits are transported through internal pipelines of the device, while the high temperature circulating water will be output through an external interface. At the same time, a water inlet, an optical fiber outlet and a high temperature water interface of the high and low temperature water interfaces are arranged on the outside of the water chiller main body shell.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] An independent and closed cabinet space is created between the fan cooling system and the water circulation system to place the drawer-type laser generator, which can save floor space compared to the conventional layout. At the same time, the low-temperature circulating water circuit originally arranged outside is arranged inside the water cooler, and the circulating water pipe can be as short as possible, which improves the cooling efficiency and prolongs the service life of the laser. At the same time, we also designed a low-temperature water circuit, which is used in conjunction with the water-cooled air-conditioning system to add an air conditioner to the cabinet where the drawer-type laser generator is placed to achieve temperature control and dehumidification. The entire device is equipped with a central control system that can monitor the working environment of the device, centrally dispatch and control the fan cooling system, water circulation system, and air-conditioning system to achieve safety and energy saving. At the same time, according to the standard network communication protocol and field bus technology, the internal data and control interface of the device are opened to realize intelligent interconnection with machine tool equipment.

[0042] See also Figure 1-3 The present invention provides a technical solution: an intelligent interconnected water-cooling machine with integrated laser, comprising:

[0043] Water-cooled machine body 1: provides an independent and closed cabinet space to protect the internal equipment from the influence of the external environment and ensure that the equipment does not affect each other.

[0044] Drawer-type laser generator 4: The laser generator is integrated in the cabinet space and is used to generate a high-energy laser beam. During operation, the laser generator generates a lot of heat and requires an effective cooling system to maintain its stable operation.

[0046] Water-cooled air conditioner 3: Works by utilizing a low-temperature circulating water circuit in the water circulation system 5; lowers the temperature of the cabinet space through the low-temperature circulating water and controls the humidity, thereby providing a suitable working environment for the laser generator and other equipment.

[0047] The fan cooling system 6 is arranged in the water-cooled machine body 1 to assist in cooling. When the cooling effect of the water circulation system is not enough to meet the cooling demand, the fan cooling system will start to take away the heat through wind power, thereby further reducing the temperature of the cabinet space.

[0048] Central integrated control system 2: integrated in the water-cooled machine body 1, it is the core of the intelligent interconnected water-cooled machine; it is intelligently interconnected with the water circulation system 5, the water-cooled air conditioner 3, the fan cooling system 6 and the drawer-type laser generator 4; it monitors the ambient temperature, humidity, water flow, water temperature and other parameters in real time through the built-in sensors; based on the monitoring data, it centrally dispatches and controls the working status of the water circulation system 5, the water-cooled air conditioner 3 and the fan cooling system 6 to ensure that the laser generator and other equipment operate in the best working environment.

[0049] The central control system supports RS485 communication and OPC UA standard network protocol, opens the internal monitoring data and control interface of the device, realizes interconnection with the laser cutting machine CNC system according to the priority set by the integrator, and supports other intelligent integration solutions; through the built-in sensor, it monitors the ambient temperature and humidity in real time, and adjusts the water temperature by season and time period with the adaptive algorithm to improve the output stability and life of the laser. At the same time, it reduces the energy consumption of the pressurized water circulation system to achieve the effect of energy saving and emission reduction; the original water chiller device vibration and laser installation chamber water immersion detection technology improves the safety and life of the laser.

[0050] The central control system 2 integrates the intelligent temperature and humidity control function, and automatically makes real-time adjustments through an adaptive algorithm that uses a polynomial chaos expansion model.

[0051] The polynomial chaos expansion model is a probabilistic statistical method that maps the model output onto an orthogonal random polynomial basis function of random input, namely

[0052]

[0060]

[0061] Among them, N P is the coefficient of the truncated expansion, whose value depends on the dimension d of the random variable and the order P, N of the polynomial expansion P It can be expressed as

[0062]

[0063] The above formula (1.5) is used to calculate the coefficients of the truncated polynomial chaos expansion model, and the truncation criterion is required to converge the optimization process. The error value must meet the threshold, which is defined as

[0064]

[0065] Among them, T L is the error ε LThe threshold is initially set to T L =0.001% to have good convergence; therefore, the coefficient value needs to be calculated in each iteration during the optimization process.

[0066] After the algorithm model is built, all relevant data from the water chiller feedback is continuously uploaded through the intelligent gateway, abnormal data is analyzed, and the algorithm model is continuously adjusted and optimized to confirm that the final controlled temperature and humidity fully meet the working needs of the laser generator.

[0067] In addition, it is necessary to install vibration and water immersion sensors inside the cavity in combination with the laser to monitor in real time whether there is water leakage and abnormal vibration in the cavity, shut down the machine in time and support fault reporting function to avoid more serious damage.

[0068] The drawer-type laser generator 4 is designed to be pluggable, allowing the laser generator to be replaced or maintained without shutting down the entire water chiller system.

[0069] 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 circuits flow through the laser generator 4 and the water-cooled air conditioner 3 respectively, absorb heat and return to the cooling part of the water circulation system for cooling treatment; the cooled low-temperature circulating water is recycled again to ensure that the laser generator 4 and the water-cooled air conditioner 3 always operate at a lower temperature; the drawer-type laser generator 4 is designed to be pluggable, and can be pulled out or inserted from the water-cooled machine body 1 through simple operations; the laser generator can be easily replaced or maintained without shutting down the entire water-cooled machine system; after the replacement or maintenance is completed, the new or repaired laser generator is inserted into the water-cooled machine body 1, and the system can continue to work normally.

[0070] The central integrated control system 2 includes a detection module for monitoring the laser power, wavelength and spot quality parameters of the laser operating state, and can automatically adjust the working state of the water circulation system 5 and the fan cooling system 6 according to these parameters; according to the laser operating state parameters obtained by the detection module, the central integrated control system 2 can intelligently judge the heat dissipation demand of the laser; if the heat dissipation demand of the laser increases, the system will automatically increase the low-temperature circulating water flow in the water circulation system 5 to reduce the temperature of the laser generator. At the same time, the working state of the fan cooling system 6 will also be adjusted accordingly to provide more effective auxiliary heat dissipation.

[0071] The water circulation system 5 includes a multifunctional sensor for detecting water flow, water temperature and water quality, and can automatically filter, heat or cool the circulating water according to the detected data to ensure the stable operation of the drawer-type laser generator 4.

[0073] The water-cooled air conditioner 3 also includes sensors for detecting the temperature and humidity inside the cabinet, and a control module for automatically adjusting the operating state of the air conditioner according to the sensor data, to ensure that the environment inside the cabinet is maintained at the state required by the laser generator.

[0074] The high and low temperature water interface 9 in the water circulation system 5 is composed of at least two low temperature circulating water circuits and one high temperature circulating water circuit. The two low temperature circulating water circuits are transported through the internal pipelines of the device, and the high temperature circulating water will be output through the external interface 10. At the same time, the water inlet 8, the optical fiber outlet 7 and the high temperature water interface of the high and low temperature water interface 9 are arranged on the outside of the shell of the water chiller main body 1, which greatly reduces the number of external wiring.

[0075] The water inlet 8 is arranged outside the shell of the water chiller body 1, and is used to provide cooling water to the water circulation system 5. The position 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.

[0076] The optical fiber outlet 7 is also arranged outside the shell of the water-cooling machine body 1, and is used for the optical fiber connection of the laser. The position and fixing method of the optical fiber outlet ensure the stable connection of the laser and the reliability of signal transmission.

[0077] The high-temperature water interface of the high- and low-temperature water interface 9 is located outside the shell of the water-cooling machine body 1 and is connected to the external interface 10 for outputting high-temperature circulating water. The temperature, flow rate, pressure and other parameters of the high-temperature circulating water are precisely controlled to ensure effective cooling and stable operation of the machine tool cutting head.
