Description

Technical Field

[0001] This utility model relates to the field of laser tube technology, specifically to an intelligent temperature-controlled water-cooling device for carbon dioxide laser tubes. Background Technology

[0002] The intelligent temperature-controlled CO2 laser tube water cooling device is a high-efficiency heat dissipation system designed specifically for CO2 laser tubes. It integrates advanced temperature sensing, intelligent control, and water circulation heat dissipation technology, aiming to precisely regulate the working temperature of the laser tube, ensure stable operation of the laser tube, and extend its service life. It is widely used in industrial fields such as laser cutting, engraving, and welding, as well as scientific research and experimental scenarios.

[0003] A search revealed a Chinese patent with publication number CN216085687U that discloses a water-cooling device for a carbon dioxide laser tube. This device cools the discharge tube by circulating cold air in a cold air pipe and cold water in a cold water pipe, thereby improving the cooling effect of the discharge tube and maintaining stable output power.

[0004] However, in the existing technology for heat dissipation of carbon dioxide laser tubes, simple air cooling or water cooling each has its limitations. Air cooling has a simple structure and low cost, but its heat dissipation efficiency is limited and it is difficult to meet the requirements of high-power laser tubes for long-term stable operation. Water cooling has a good heat dissipation effect, but there is a risk of water leakage, requirements for water quality, and the device is relatively complex. By combining air cooling and water cooling, the aim is to take advantage of each other's strengths and make up for their weaknesses, so as to achieve efficient heat dissipation, improve system stability, reduce costs and maintenance difficulty, and ensure that the laser tube can maintain a suitable operating temperature under various operating conditions. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] In view of the above-mentioned background technology, the existing technology has the disadvantages and defects of simple air cooling structure and low cost but limited heat dissipation efficiency, while water cooling has the risk of water leakage, requirements for water quality and relatively complex and expensive device.

[0006] The present invention discloses an intelligent temperature-controlled carbon dioxide laser tube water-cooling device, which includes a shell, a discharge tube disposed inside the shell, a support frame disposed between the two ends of the discharge tube and the shell, an air-cooling component disposed at one end of the shell, and a water-cooling component disposed at the other end of the shell.

[0007] Furthermore, the water-cooling assembly includes a cooling pipe, a water inlet, and a water outlet. The cooling pipe is spirally sleeved on the discharge pipe. The water inlet at one end of the cooling pipe is connected to an external water tank, and the water outlet at one end of the cooling pipe is connected to an external radiator.

[0008] Furthermore, the air-cooling component includes an exhaust fan, and multiple exhaust fans are provided, which are evenly distributed. A fixing component is provided between the exhaust fan and the outer casing.

[0009] Furthermore, the fastener includes a fixing bolt, which is installed on the housing. The exhaust fan has a mounting hole through which the fixing bolt passes. A threaded cap is provided on the fixing bolt, and the threaded cap is threadedly connected to the fixing bolt.

[0010] Furthermore, a filter screen is provided on the side of the outer casing away from the exhaust fan, and a limiting member is provided between the filter screen and the outer casing.

[0011] Furthermore, the limiting component includes a locking plate, and two locking plates are provided. One locking plate is fixedly installed on the outer shell, and the other outer shell is slidably installed on the outer shell. The locking plate slidably installed on the outer shell is provided with a limiting groove, and a limiting post is provided on one side of the limiting groove. The limiting post is fixedly connected to the outer shell through a guide plate, and the guide plate is slidably installed with the corresponding locking plate.

[0012] Furthermore, a heat dissipation fin is provided between the filter screen and the exhaust fan, and the heat dissipation fin is mounted on the outer casing.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model first utilizes the airflow generated by the exhaust fan to remove some of the heat from the surface of the discharge tube. This stage can handle the small amount of heat generated when the discharge tube is running under low load, reducing the pressure of subsequent cooling. After the primary cooling, the discharge tube still has a lot of heat accumulated. At this time, the cooling tube works, and the coolant flows in the cooling tube and is in close contact with the laser tube. Due to the high specific heat capacity of water, a large amount of heat is absorbed, further reducing the temperature of the laser tube. This achieves the combination of air cooling and water cooling, which not only achieves efficient heat dissipation, but also improves system stability, reduces costs and maintenance difficulty, and ensures that the laser tube can maintain a suitable working temperature under various operating conditions.

[0015] 2. This utility model, by incorporating components such as a filter screen, a retaining plate, a guide plate, a limiting post, and heat dissipation fins, filters impurities in the air during operation, reducing the amount of dust and impurities entering the housing. The retaining plate, guide plate, and limiting post components work together to restrict the position of the filter screen. By driving the retaining plate to move and separate from the filter screen, the restriction on one end of the filter screen is released, allowing the filter screen to be disassembled. The heat dissipation fins increase the heat dissipation area, thereby improving the heat dissipation effect. Attached Figure Description

[0022] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0023] Please see Figure 1 , Figure 2 , Figure 4 The present invention relates to an intelligent temperature-controlled carbon dioxide laser tube water-cooling device, comprising a housing 1, a discharge tube 2 disposed inside the housing 1, a support frame 3 disposed between the two ends of the discharge tube 2 and the housing 1, an air-cooling component disposed at one end of the housing 1, and a water-cooling component disposed at the other end of the housing 1.

[0024] High-precision thermistor temperature sensors are installed on key parts of the discharge tube 2 surface and at the outlet of the water-cooling assembly to monitor temperature changes in real time and provide feedback to the controller. The sensor accuracy can reach ±0.5℃, ensuring accurate temperature monitoring. The controller, a microprocessor-based intelligent controller, receives the temperature sensor signals and automatically adjusts the rotation speed of the air-cooling assembly and the flow rate of the water-cooling pump according to the preset temperature threshold. When the temperature of discharge tube 2 rises to near the upper limit, the controller increases the intensity of air cooling and water cooling; when the temperature drops to the lower limit, it correspondingly reduces the heat dissipation to maintain temperature stability, thereby achieving intelligent control.

[0025] In this embodiment, the water cooling assembly includes a cooling pipe 4, a water inlet 5, and a water outlet 6. The cooling pipe 4 is spirally sleeved on the discharge pipe 2. The water inlet 5 at one end of the cooling pipe 4 is connected to an external water tank, and the water outlet 6 at one end of the cooling pipe 4 is connected to an external radiator.

[0026] like Figure 1 , Figure 2 As shown, the air-cooled assembly includes an exhaust fan 7, and multiple exhaust fans 7 are provided. The multiple exhaust fans 7 are evenly distributed, and a fixing component is provided between the exhaust fan 7 and the outer casing 1.

[0027] In this embodiment, the fixing component includes a fixing bolt 8, which is installed on the outer casing 1. The exhaust fan 7 is provided with a mounting hole 9, through which the fixing bolt 8 passes. A threaded cap 10 is provided on the fixing bolt 8, which is threadedly connected to the fixing bolt 8. By removing the threaded cap 10 from the fixing bolt 8, the fixing of the exhaust fan 7 is released, thereby enabling the exhaust fan 7 to be disassembled. The exhaust fan 7 can then be installed by reversing the operation.

[0028] See Figure 2 , Figure 3 As shown, a filter screen 12 is provided on the side of the outer casing 1 away from the exhaust fan 7. A limiting component is provided between the filter screen 12 and the outer casing 1. The filter screen 12 filters impurities in the air, thereby preventing impurities from entering the outer casing 1.

[0029] The limiting component includes a locking plate 13. Two locking plates 13 are provided. One locking plate 13 is fixedly installed on the outer shell 1, and the other outer shell 1 is slidably installed on the outer shell 1. The locking plate 13 slidably installed on the outer shell 1 is provided with a limiting groove 16. A limiting post 15 is provided on one side of the limiting groove 16. The limiting post 15 is fixedly connected to the outer shell 1 through a guide plate 14. The guide plate 14 is slidably installed with the corresponding locking plate 13. By driving the locking plate 13 to slide, the locking plate 13 is separated from the filter screen 12, thereby releasing the restriction on the filter screen 12. Then the filter screen 12 can be pulled out and replaced. After replacement, the locking plate 13 is moved in the direction until the limiting groove 16 on the locking plate 13 engages with the limiting post 15. The limiting post 15 restricts the position of the locking plate 13 and prevents the locking plate 13 from sliding.

[0030] A heat dissipation fin 11 is provided between the filter screen 12 and the exhaust fan 7. The heat dissipation fin 11 increases the heat dissipation area, thereby improving the heat dissipation effect. The heat dissipation fin 11 is installed on the outer casing 1.

[0031] The implementation principle is as follows: During the operation, the exhaust fan 7 is first controlled to work. The airflow generated by the exhaust fan 7 will remove some of the heat from the surface of the discharge tube 2. The cold air blows directly on the discharge tube 2, and the heat is quickly dissipated to the surrounding environment through heat conduction. This stage can deal with the small amount of heat generated when the discharge tube 2 is running under low load, and reduce the pressure of subsequent cooling. Then the water cooling system is started, and the coolant circulates in the cooling tube 4 that is in close contact with the laser tube. Due to the high specific heat capacity of water, a large amount of heat is absorbed, and the temperature of the laser tube is further reduced.

[0032] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
