Description

Technical Field

[0001] The utility model belongs to the technical field of lasers, and particularly relates to an air-cooled laser and a centralized heat dissipation laser system. Background Art

[0002] Traditional water-cooled lasers require dedicated cooling water circulation equipment, including chillers, water pipelines, and water circulation / processing systems, etc. This not only increases the equipment cost, but also the additional chiller equipment takes up more space, which may not be very friendly to work sites with limited space. The installation of water-cooled lasers is relatively complex and requires professional personnel to arrange the water pipelines and carry out waterproof treatment to prevent leakage. At the same time, the cooling water needs to be regularly inspected and replaced to prevent the growth of microorganisms, corrosion, or blockage of the pipelines, increasing the maintenance workload. Similarly, traditional water-cooled lasers also bring potential water leakage risks: water leakage may occur at the pipe joints or pump body aging. Minor water leakage may affect the environment and equipment safety, and in severe cases, it may even cause safety hazards such as electrical short circuits. The water cooling system is greatly affected by the ambient temperature. Especially in extremely cold conditions, the cooling water may freeze, and antifreeze needs to be added or other anti-freezing measures need to be taken. The air-cooled laser is more flexible in this regard.

[0003] Existing air-cooled lasers rely solely on fans for cooling, and their cooling efficiency cannot meet the requirements in some high-power laser processing scenarios. Therefore, an air-cooled laser that can efficiently cool down is needed. Summary of the Utility Model

[0043] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0044] This application provides an air-cooled laser and a centralized heat dissipation laser system, which will be described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of this application. And in the following embodiments, each embodiment is described with emphasis. For parts not detailed in a certain embodiment, reference may be made to the relevant descriptions of other embodiments.

[0045] See Figure 1 and Figure 2 , in an embodiment of the present application, the air-cooled laser includes: a housing 1; a plurality of heat dissipation fins 2 disposed inside the housing 1; a plurality of heat dissipation plates 3 disposed inside the housing 1; a plurality of heat dissipation fans 4 disposed on the housing 1; and a cold air pipe 5 wound inside the housing 1.

[0046] In this embodiment, the heat dissipation plates 3 and the heat dissipation fins 2 may be located near the pump source and the laser gain cavity for cooling the internal crystal; the heat dissipation plates 3 may be, but are not limited to, directly installed near or in direct contact with high-heat generating components inside the laser, such as close to the laser diode module, power module, etc.

[0047] In this embodiment, the heat dissipation plates 3 and the heat dissipation fins 2 may be located on the key path of the cold air pipe 5, and the cold air pipe 5 can directly take away the heat generated by the components.

[0048] See Figure 2 , in this embodiment, optionally, the plurality of heat dissipation plates 3 are spaced apart; the cold air pipe 5 passes through the gap between adjacent heat dissipation plates 3.

[0049] To meet different scenarios and requirements, common materials for heat sink 3 and heat sink fins 2 include 6061 and 6063 aluminum alloys, which are suitable for the heat dissipation needs of most low- and medium-power lasers, as well as cost-sensitive applications. Composite materials such as aluminum-based copper-clad graphene-reinforced materials are also used, which are suitable for high-end laser products that pursue extreme heat dissipation efficiency and lightweight design, especially portable devices or those with strict weight restrictions. Heat sink 3 can be designed with many thin lamellae, which greatly increase the surface area in contact with the air, thereby improving the efficiency of heat transfer from the laser's internal components to the air. The shape and layout of heat sink 3 help guide airflow, allowing air in the air duct to flow more efficiently through each heat sink, removing heat and ensuring that the temperature around the heat source does not rise too high. Through large-area contact, the heat sink can quickly disperse heat concentrated in the laser diode, crystal, or other high-heat-generating components, avoiding local overheating and protecting sensitive components.

[0050] Furthermore, a first heat dissipation fin 21 and a second heat dissipation fin 22 are respectively provided at both ends of the heat dissipation plate 3. A groove 211 is provided on the surface of the first heat dissipation fin 21; the groove 211 is used for embedding the cold air pipe 5.

[0051] See also Figure 1 and Figure 2 The inlet connector 51 and the outlet connector 52 of the cold air pipe 5 are both provided on the first end surface of the shell 1. The inlet connector 51 can be used to connect to a cold air source, and the outlet connector 52 can be used to connect to an exhaust pipe.

[0052] Optionally, a filter 53 is provided on the inlet and / or outlet of the cooling pipe 5. This can prevent external dust and impurities from entering the laser, reduce pollution, and protect precision components from damage. At the same time, it also ensures unimpeded airflow in the cooling pipe 5 and unaffected heat dissipation.

[0053] Furthermore, a plurality of first cooling fans 41 are provided on the first end surface, and a second cooling fan 42 is provided on the top surface of the housing 1. In some embodiments, the first cooling fans 41 and the second cooling fans 42 can exhaust air outwards.

[0054] Accordingly, see Figure 4 and Figure 5 An embodiment of the present application further provides a centralized heat dissipation laser system, comprising: a rack 100; the air-cooled laser 200 as described above, mounted on the rack 100; an electric control module box 300, mounted on the rack 100; a refrigeration compression device 400, which is connected to the inlet joint 51 of the cooling air pipe 5 of the air-cooled laser through a first cooling pipe 500, and supplies cold air to the electric control module box 300 through a second cooling pipe 600.

[0055] In this embodiment, the refrigeration compression device 400 can be implemented by existing technologies and can be purchased from the market.

[0056] Furthermore, the centralized heat dissipation laser system further includes an exhaust pipe 700; the outlet joint 52 of the cold air pipe 5 of the air-cooled laser is communicated with the exhaust pipe 700 through a cold air outlet pipe 521; the air outlet of the electronic control module box 300 is communicated with the exhaust pipe 700, and an exhaust fan 310 is arranged at the air outlet.

[0057] In this embodiment, the refrigeration compression device 400 can supply cold air to both the air-cooled laser 200 and the electronic control module box 300 at the same time, and can cool both of them at the same time. Among them, the process of cooling the air-cooled laser 200 is as described above; the process of cooling the electronic control module box 300 is that the cold air generated by the refrigeration compression device 400 enters the electronic control module box 300 through the second cold supply pipe 600, so that the heat generated during the long-term processing process is taken away by the refrigerated air. There is an exhaust fan 310 at the air outlet, which takes away the hot air, and the hot air is discharged through the exhaust pipe 700 together with the exhaust pipe of the air-cooled laser 200.

[0058] Optionally, an industrial personal computer 110 and a display 120 are further arranged on the frame 100.

[0059] In summary, the air-cooled laser and the centralized heat dissipation laser system of the present utility model effectively improve the continuous service life of the laser by air-cooling, and at the same time greatly improve the heat dissipation capacity of the machine; it solves the problems that under the influence of heat conduction and heat convection factors during long-term working conditions, the temperature of the circuit board rises, accelerating the aging of components and poor stability.
