[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0023] For the convenience of explanation, only the parts related to the embodiment of the present utility model are shown.

[0024] Combination Figure 1-3 and Figure 6 As shown, the laser includes a pump device 1. The laser cooling assembly includes water-cooling plates respectively arranged on both sides of the pump device. One end of the water-cooling plate has a water inlet 22 and a water outlet 21. The water-cooling plate includes a rectangular plate 1 23 and a rectangular plate 24 connected to each other. The rectangular plate 2 is close to the pump assembly. The rectangular plate 1 has a water-cooling tube 1 25, and the water outlet is connected to one end of the water-cooling tube 1. The rectangular plate 2 has a water-cooling tube 26 with the same direction as the water-cooling tube 1, and the water inlet is connected to one end of the water-cooling tube 2. The side of the rectangular plate 1 is also provided with a channel 1 27 connected to the other end of the water-cooling tube 1, and the side of the rectangular plate 2 is also provided with a channel 2 28 connected to the other end of the water-cooling tube 2 and corresponding to the channel 1. The water-cooling tube 1 and the water-cooling tube 2 are curved, and the rectangular plate 1 and the water-cooling tube 2 are rectangular. Screw holes are opened correspondingly on the rectangular plate 1 and the rectangular plate 2, and the rectangular plate 1 and the rectangular plate 2 are fixed at the screw holes by fastening screws and fastening nut structures. The channel 1 and the channel 2 are connected by a rubber hose. A plurality of rubber strips 3 are arranged on the side of the water-cooling plate on one side of the pump device, and a plurality of locking boxes 45 corresponding to the rubber strips are arranged on the side of the water-cooling plate on the other side of the pump device. The locking box has a slot 41 for inserting the rubber strip, and a through hole 42 is formed on the slot. A driving member 43 is arranged in the locking box, and the driving member includes a connected servo motor and a reducer. A transmission gear 44 is connected to the output shaft of the driving member. The rubber strip has a serrated portion, and some serrations on the transmission gear pass through the through hole and can mesh with the serrated portion.

[0025] The pump device on the laser will generate a lot of heat during operation. The two water-cooling plates on the cooling assembly are respectively placed on the two sides of the pump device, and the rubber strip on the water-cooling plate on one side of the pump device is inserted into the locking box on the water-cooling plate on the other side of the pump device. The rubber strip cooperates with the slot in the locking groove, and the driving member in the locking box drives the transmission gear to rotate. Some of the serrations on the transmission gear also pass through the through hole on the slot and mesh with the serrations on the rubber strip, so that the transmission gear rotates while also locking the rubber strip, so that the water-cooling plates on both sides of the pump device achieve a stable connection with the pump device. The driving member drives the transmission gear to rotate in the opposite direction, and the transmission gear can drive the rubber strip to move away from the locking box. The rubber strip is flexible and will deform after being acted upon by the transmission gear to move it out of the locking box, thereby preventing the water-cooling plate connected to the rubber strip from hindering the rubber strip from moving out of the locking box. When the water-cooling plate is stably connected to both sides of the pump device, cooling water is passed from the water inlet on the rectangular plate 2 to the water-cooling tube 2. The water temperature in the water-cooling tube 2 increases from the water inlet to the channel 2. The cooling water enters the water-cooling tube 1 on the rectangular plate 1 through the channel 1 from the channel 2. The water temperature in the water-cooling tube 1 gradually decreases from the channel 1 to the water outlet. The water-cooling tube 1 and the water-cooling tube 2 are both curved and have the same direction. With this arrangement, after the heat exchange between the water-cooling tube 1 and the water-cooling tube 2, the water temperature between the two will be relatively uniform, so that the heat dissipation effect of the water-cooling plate on the pump device is also relatively uniform.

[0026] Combination Figure 4-5 As shown, the middle of rectangular plate 1 has a cavity, water-cooling tube 1 is arranged in the cavity, and heat sinks 53 are also arranged in the cavity on both sides of water-cooling tube 1. A grid-shaped heat dissipation rib 51 is formed on the side of the heat sink away from water-cooling tube 1. The heat sink also has an arc-shaped protruding groove 52 that matches the shape of water-cooling tube 1. A plurality of heat dissipation holes 231 are evenly spaced at the outer edge of rectangular plate 1. The structure of rectangular plate 2 is the same or similar to that of rectangular plate 1, and will not be repeated here. Heat sinks are arranged on both sides of water-cooling tube 1 and water-cooling tube 2, so as to achieve better heat dissipation of water-cooling tube 1 and water-cooling tube 2. The heat sink has a mesh heat dissipation rib, which expands the heat dissipation area of ​​the heat sink. The heat sink also has an arc-shaped protruding groove 1 or an arc-shaped protruding groove 2 that matches the shape of water-cooling tube 1 or water-cooling tube 2, which expands the heat absorption area of ​​the heat sink to absorb the heat in water-cooling tube 1 or water-cooling tube 2, thereby optimizing the heat dissipation effect of the heat sink, that is, optimizing the heat dissipation effect of the water-cooling plate on the pump device.

[0027] In summary: The utility model provides a laser cooling component, which is provided with water cooling plates on both sides of the pump device, and the sides of the water cooling plates are respectively provided with rubber strips and locking boxes, and the rubber strips and the locking boxes are locked by the mutual meshing of the serrated portion on the rubber strips and the transmission gear in the locking box, thereby conveniently realizing the stable connection between the water cooling plates on both sides of the pump device and the pump device, and also helping to improve the cooling effect of the water cooling plate on the pump device. The water cooling plate in the laser cooling component is composed of a rectangular plate 1 and a rectangular plate 2, and the cooling water flows to the water cooling tube 1 on the rectangular plate 1 through the water cooling tube 2 on the rectangular plate 2, and the cooling water in the water cooling tube 1 and the water cooling tube 2 exchange heat with each other, which helps to evenly dissipate the heat of the pump device. The laser cooling component is provided with heat dissipation plates on both sides of the water cooling tube 1 in the rectangular plate 1, which are used to assist the water cooling tube 1 in heat dissipation, and optimize the cooling effect of the water cooling plate on the pump device.
