Description

Technical Field

[0001] The invention relates to the technical field of cooling devices, and in particular to a laser cooling device. Background Art

[0002] As a high-power, high-efficiency light source, lasers have been widely used in many fields, such as communications, medical treatment, material processing, scientific research, etc. However, lasers generate a lot of heat during operation, especially high-power lasers, which generate more significant heat. If this heat cannot be effectively dissipated, the temperature of the laser will rise, thereby affecting the performance and stability of the laser and even shortening its service life. Therefore, effective cooling of the laser becomes one of the key factors to ensure its normal operation. Laser cooling technologies mainly include air cooling, water cooling and liquid cooling. Air cooling is usually used for low-power lasers because its heat dissipation capacity is weak and cannot meet the needs of high-power lasers. Water cooling is a more common cooling method. Its advantage is that water has a large specific heat capacity and strong heat dissipation capacity. Summary of the invention

[0003] The purpose of the present invention is to solve the problem that various components of the cooling system may become loose due to vibration, external force or temperature change, resulting in reduced heat exchange effect or even damage to the equipment. This solution can effectively fix the cooling plate and other components by introducing locking devices and clamping devices to avoid uneven heat dissipation or equipment damage due to loosening or deformation. At the same time, this adjustable method can meet the problems of lasers of different models and sizes.

[0004] The present invention achieves the above-mentioned purpose through the following technical solutions: A laser cooling device, comprising a circulating cooling device, a locking device is arranged at the bottom of the circulating cooling device, a laser head is arranged inside the circulating cooling device, the circulating cooling device comprises a first cooling plate, a second cooling plate is arranged on one side of the first cooling plate, the first cooling plate comprises heat dissipation fins, a serpentine circulating cold and hot pipe is arranged through the inner side of the heat dissipation fins, a water inlet is arranged at a corner of the upper end of the first cooling plate and the second cooling plate, a water outlet is arranged at the oblique side opposite corner of the water inlet, a plurality of clamping devices are arranged at the upper ends of the first cooling plate and the second cooling plate, a guide tube is arranged between the first cooling plate and the second cooling plate To the connecting column, through the combined design of heat dissipation fins, serpentine hot and cold pipes and cooling plates, the heat exchange area and liquid contact area are increased, thereby significantly improving the heat transfer and dissipation efficiency. The locking device and clamping device ensure the stability of each part of the cooling system, avoiding the decline in heat dissipation effect or equipment damage caused by the loosening of the cooling system. Through the reasonable arrangement of the water inlet and outlet, the flow of the coolant is smoother, which can achieve uniform and efficient heat exchange and avoid local overheating problems. The first cooling plate is used in conjunction with the second cooling plate and is designed as a compact structure, which can effectively save space and simplify the assembly of the cooling system. It can also be tried on different lasers.

[0005] Furthermore, the clamping device includes a fixing block, positioning holes are provided on both sides of the bottom of the fixing block, guide columns are provided on both sides of the upper end of the fixing block, and locking bolts are connected through the middle of the fixing block and the pressing block. Through the joint design of the fixing block, the guide column, the pressing block and the locking bolts, the clamping device can firmly fix the cooling plate and other components, avoiding the decrease in heat exchange efficiency or equipment damage due to loosening or deformation. The design of the positioning holes and guide columns can ensure that the cooling plate and its related components are accurately aligned during the assembly process, avoiding unstable operation due to improper assembly. The fixing block is firmly connected to the pressing block through the locking bolts. The clamping device has enhanced vibration resistance and can maintain its stability during long-term operation of the equipment, avoiding the decrease in heat dissipation performance or component damage due to vibration.

[0006] Furthermore, the locking device includes a fixing part, a locking rack is fixedly connected to the upper end of the fixing part, a fixed locking hole is provided on the locking rack, the locking rack is movably connected to the snapping part through plugging and pulling, and through the meshing design of the locking rack and the snapping part, the locking device can provide extremely strong fixing force to ensure that each component remains stable during work and is not easy to loosen or fall off. The plug-in and pull-out design of the snapping part makes the entire locking process very convenient, especially when quick maintenance or component replacement is required, which can greatly improve work efficiency. The close fit between the snapping part and the locking rack helps to maintain the firmness of the connection during long-term use, and avoid loosening or wear due to long-term vibration or load.

[0007] Furthermore, the guide connection column, the fixing member and the locking rack are all fixedly connected to the first cooling plate, and the snap member is fixedly connected to the second cooling plate.

[0008] Furthermore, the locking rack is connected to the buckle piece by plugging and unplugging.

[0009] Furthermore, the positioning hole is fixedly connected to the first cooling plate and the second cooling plate through locking bolts.

[0010] Furthermore, the first cooling plate and the second cooling plate are both L-shaped and spliced, and the heat dissipation fins are all arranged on the side walls of the L-shape.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The combined design of heat dissipation fins, serpentine hot and cold pipes and cooling plates greatly increases the heat exchange area and liquid contact area, significantly improving the efficiency of heat transfer and dissipation. The heat dissipation fins increase the surface area, and the serpentine hot and cold pipes optimize the liquid flow path to ensure uniform and efficient heat exchange. This design can effectively prevent local overheating and improve the working stability and life of the laser; 2. The design of the locking device and the clamping device provides a firm fixation for each part of the cooling system, avoiding the cooling system from loosening and causing a decrease in heat dissipation or damage to the equipment. The clamping device ensures the precise alignment of the cooling plate and related components during the assembly process through components such as positioning holes, guide columns and locking bolts, enhances the anti-vibration ability, and contributes to the stability and reliability of the system in long-term operation; 3. The first cooling plate and the second cooling plate adopt an L-shaped splicing structure with a compact design, which not only saves space but also simplifies the assembly process of the cooling system. At the same time, the plug-in connection design of the locking rack and the buckle makes the entire locking process more convenient, especially when rapid maintenance or replacement of parts is required, which greatly improves work efficiency. In addition, the modular design of the cooling device enables it to be applied to different types of lasers and has good versatility.

[0012] 4. Through the rational arrangement of water inlets, outlets and guide posts, the coolant flows more smoothly, avoiding uneven flow and dead corners. The guide posts ensure that the coolant is evenly distributed throughout the system, avoiding local overheating and achieving efficient heat exchange. This optimized flow path not only improves cooling performance, but also ensures that the coolant can fully contact every part of the cooling plate, maximizing the overall cooling effect.
