[0029] The technical solutions in the embodiments of the present application will be apparently and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0030] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. EMBODIMENT

[0031] The embodiment of the present application discloses a flow-controllable water-cooled laser cooler. Referring to Figure 1 , Figure 2 and Figure 3 , comprising: a water cavity 1, including one water inlet channel 11 and two water outlet channels 12, the two water outlet channels 12 are arranged on one side of the water cavity 1, the water inlet channel 11 is arranged on the opposite side of the two water outlet channels 12, and the two water outlet channels 12 are in communication with the water inlet channel 11; two water outlet rotating screw holes 3 are arranged at the two water outlet channels 12 respectively, and are perpendicular to the water flow direction of the water outlet channel 12, and are penetrated from the water outlet channel 12 to the external environment; two water outlet adjusting valves 13 are installed in the two water outlet rotating screw holes 3 respectively, for controlling the water flow of the two water outlet channels 12 respectively, and the two water outlet adjusting valves 13 correspond to the two water outlet rotating screw holes 3 one by one; a gas decompression groove 2 is arranged at the two water outlet channels 12, and extends in the direction opposite to the external environment from the water outlet rotating screw hole 3, the gas decompression groove 2 is penetrated with the water outlet rotating screw hole 3, and is used for balancing the gas pressure and water pressure at the water outlet channel 12 in the adjusting process of the water outlet adjusting valve 13.

[0032] Based on the above structure, the two water outlet channels 12 respectively outlet water, and the two water outlet channels 12 are connected to the laser, so as to realize the effect of water cooling for the laser. By arranging the water outlet adjusting valve 13 at the water outlet channel 12, the opening and closing size of the two water outlet adjusting valves 13 can be adjusted, the water flow size at the water outlet channel 12 can be adjusted, and whether the water outlet channel 12 outlets water can be controlled based on the closing or opening of the water outlet adjusting valve 13, so as to realize the effect that only one side of the laser is cooled when the temperature of one side of the laser is too high.

[0033] Referring to Figure 3 , wherein Figure 3 is also Figure 1 a cross-sectional view at the dotted line. To ensure that the outlet water regulating valve 13 can block the outlet water channel 12 and can be fixed near the outlet water channel 12, the outlet water rotating screw hole 3 is arranged, which effectively ensures the control effect of the outlet water regulating valve 13.

[0034] Optionally, the gas pressure reduction groove 2 is arranged, that is, arranged on one side of the outlet water channel 12 and opposite to the outlet water regulating valve 13. When the outlet water regulating valve 13 is closed, the outlet water channel 12 is completely blocked, and the end of the outlet water regulating valve 13 also blocks the gas pressure reduction groove 2, so that a certain gas pressure is formed in the gas pressure reduction groove 2. When the gas pressure reduction groove 2 is opened again, the gas rises, and the liquid flows into the gas pressure reduction groove 2, thereby buffering the flow rate of the liquid and avoiding the impact of the liquid on the laser.

[0035] Optionally, by arranging the outlet water regulating valve 13 and the gas pressure reduction groove 2 at the outlet water channel 12, the flow rate of the water flow can be effectively controlled, thereby targetedly cooling the part position of the laser, improving the cooling effect of the laser, and buffering the water source to avoid impacting the laser.

[0036] Preferably, in the embodiment, the gas pressure reduction groove 2 is in a conical shape, the tip of the conical shape is away from the outlet water channel 12, and the circular face end of the conical shape is through the outlet water channel 12.

[0037] Referring to Figure 2 , based on the above structure, after the liquid enters the conical gas pressure reduction groove 2, the liquid is blocked by the inclined side wall, thereby achieving the buffering effect of the liquid. After the liquid is forced on the inclined side wall, the side wall simultaneously applies an inclined outward force to the liquid, so that the liquid entering the conical shape can be flushed out by the subsequent water source, and the subsequent water source enters the conical gas pressure reduction valve.

[0038] Optionally, if the gas pressure reduction valve is arranged as a rectangular recess hole, the liquid entering the gas pressure reduction valve may be affected by the vertical side wall and cannot flow outwards, thereby remaining in the place and forming a water film above, that is, the subsequent water source does not enter the gas pressure reduction valve for buffering, thereby causing the gas pressure reduction valve to lose the effect.

[0039] Preferably, in the embodiment, the outlet water regulating valve 13 is provided with a thread, the thread is matched with the outlet water rotating screw hole 3, the outlet water regulating valve 13 is installed in the outlet water rotating screw hole 3, and moves in the direction close to or away from the outlet water channel 12.

[0040] Based on the above structure, the water outlet adjusting valve 13 is screwed with the water outlet rotating screw hole 3, so as to realize the rotation of the water outlet adjusting valve 13 in the up-down direction, i.e. in the direction of approaching or moving away from the water outlet channel 12. When the water outlet adjusting valve 13 rotates away from the water outlet channel 12, liquid can flow out through the water outlet channel 12.

[0041] The preferred embodiment further comprises a height reminder arranged inside the water cavity 1, located outside the water outlet rotating screw hole 3, and the height exceeds the diameter of the water outlet channel 12, for reminding the rotation height of the water outlet adjusting valve 13 exceeding the diameter of the water outlet channel 12.

[0042] Based on the above structure, in order to remind the staff that the rotation height of the water outlet adjusting valve 13 has exceeded the diameter of the water outlet channel 12 when rotating the water outlet adjusting valve 13, i.e. the water outlet channel 12 is completely opened, a height reminder is arranged, which will have a slight vibration feeling after the water outlet adjusting valve 13 is lifted, i.e. a "click" sound after rotating to a certain degree in the mechanism, thereby realizing the reminding of the staff on the opening state of the water outlet channel 12.

[0043] The preferred embodiment of the height reminder comprises a mounting hole 32 arranged outside the water outlet rotating screw hole 3 in a ring shape, and an elastic ring 33 with a circular cross-section arranged in the mounting hole 32, and the part close to the inner wall of the mounting hole 32 is fixed in the mounting hole 32, and the elastic ring 33 is made of elastic metal material.

[0044] Based on the above structure, the height reminder mainly adopts the arrangement of the mounting hole 32 at the height exceeding the diameter, and the elastic ring 33 is placed in the mounting hole 32. The mounting hole 32 is a groove dug on the surface of the water outlet rotating screw hole 3, and an elastic metal ring is placed in the groove. The water outlet adjusting valve 13 passes through the metal ring. During the upward rotation of the water outlet adjusting valve 13, until the lowermost end of the water outlet adjusting valve 13 reaches the elastic ring 33. At the moment when the water outlet adjusting valve 13 leaves the elastic ring 33, the expansion force of the elastic ring 33 disappears, causing the slight contraction of the elastic ring 33, which can cause a perceivable vibration and a "click" sound.

[0045] Optionally, the elastic ring 33 needs to be circular and slightly flexible, and the side closest to the water outlet adjusting valve 13 is equal to or slightly smaller than the diameter of the water outlet adjusting valve 13, so as to ensure that the water outlet adjusting valve 13 can be squeezed into the gap between the outer surface of the circular ring and the middle of the circular ring when rotating downward (when closing the water outlet channel 12).

[0046] The preferred embodiment further comprises a sealing gasket 15 arranged at the end of the water outlet adjusting valve 13 and located close to one end of the water outlet channel 12.

[0047] Reference Figure 4 Based on the above structure, in order to ensure that the water outlet channel 12 is completely sealed, a sealing gasket 15 is provided at the end of the water outlet regulating valve 13. The sealing gasket 15 is made of silicone material, which effectively seals the water outlet channel 12.

[0048] In this preferred embodiment, the water inlet rotating screw hole 31 is disposed at the water inlet channel 11 and is perpendicular to the water flow direction of the water inlet channel 11, extending from the water inlet channel 11 to the external environment; the water inlet regulating valve 14 is disposed at the water inlet channel 11 and is used to control the water inlet flow rate at the water inlet channel 11; the water inlet regulating valve 14 is matched with the water inlet rotating screw hole 31 and moves in the direction close to or away from the water inlet channel 11.

[0049] Based on the above structure, to ensure that the inlet regulating valve 14 can block the inlet channel 11 and can be fixed near the inlet channel 11, an inlet rotating screw hole 31 is provided. The inlet regulating valve 14 is screwed together with the inlet rotating screw hole 31, thereby realizing the rotation of the inlet regulating valve 14 to move left and right, that is, to move in the direction of approaching or moving away from the inlet channel 11. When the inlet regulating valve 14 rotates away from the inlet channel 11, the liquid can flow into the water chamber 1 through the inlet channel 11.

[0050] Optionally, an inlet regulating valve 14 can be provided. When the device is not in use, the inlet regulating valve 14 can be closed to stop the heat dissipation device from working, effectively avoiding the problem of water waste caused by continuous water outflow.

[0051] In this preferred embodiment, the pagoda nozzle 4 is installed at the water inlet channel 11 and is shaped like a frustum. The end of the frustum with a smaller diameter is away from the water inlet channel 11, and the end of the pagoda nozzle 4 away from the water inlet channel 11 is connected to a water pipe. Two pagoda heads 5 are installed at the two water outlet channels 12 respectively, both of which are shaped like a frustum. The end of the frustum with a smaller diameter is away from the two water outlet channels 12, and the end of the pagoda head 5 away from the two water outlet channels 12 is connected to the water injection end of the laser.

[0052] Reference Figure 5 Based on the above structure, both the pagoda head 5 and the pagoda nozzle 4 are pagoda-shaped connectors, which are key components used to connect pipes in the piping system. They have a conical appearance, with one end larger and the other end smaller, similar to a mini pagoda.

[0053] Optionally, the pagoda head 5 and the pagoda nozzle 4 are fixed to the surface of the water cavity 1 with bolts. One end of the pagoda nozzle 4 is connected to a water source. The water source enters the water cavity 1 through the pagoda nozzle 4, and reaches the pagoda head 5 through the water outlet 12. The pagoda head 5 is connected to the laser, thereby enabling the water source to enter the laser for cooling.

[0054] Optionally, due to the taper structure of the tower head 5 and the tower mouth 4, one end of the tower mouth 4 can be connected to a water pipe of any diameter, and in the case of a larger diameter of the water pipe, the overlapping part between the tower mouth 4 and the water pipe is larger. Similarly, the tower head 5 can also adapt to the water cooling port of different lasers.

[0055] Preferably, in the embodiment, the first flexible clamping buckle 6 is provided in multiple numbers and uniformly distributed on the tower mouth 4 in a circular truncated cone shape, and the small-diameter end of the circular truncated cone shape is away from the water inlet hole 11. The first flexible clamping buckle 6 is made of flexible steel material. The second flexible clamping buckle 7 is provided in multiple numbers and uniformly distributed on the tower head 5 in a circular truncated cone shape, and the small-diameter end of the circular truncated cone shape is away from the water outlet hole 12. The second flexible clamping buckle 7 is made of flexible steel material.

[0056] Based on the above structure, in order to avoid the water pipe from falling off the tower mouth 4, multiple first flexible clamping buckles 6 are arranged on the tower mouth 4, and the first flexible clamping buckles 6 are also tapered structures, so that the tower mouth 4 has a stacked tower shape, which can effectively adapt to different water pipes. At the same time, the larger-diameter end of the first flexible clamping buckle 6 clamps the water pipe, thereby avoiding the water pipe from being washed off due to high water pressure.

[0057] Optionally, the tower mouth 4 is made of a steel pipe with a diameter of 15 mm or a steel pipe with a diameter of 16 mm, and the tower head 5 is made of a steel pipe with a diameter of 8 mm.

[0058] Preferably, in the embodiment, the fixed support 8 is connected to the water cavity 1 at one end and connected to the laser at the other end, and is used for fixing the water cavity 1 to the laser.

[0059] Based on the above structure, the fixed support 8 is arranged to fix the water cavity 1 to the laser, that is, one end of the fixed support 8 is inserted into the water cavity 1, and the other end is inserted into the corresponding aperture of the laser. Alternatively, the water cavity 1 can also be fixed to the bottom surface, and only the water cavity 1 needs to be fixed, which will not shake under the action of water pressure.

[0060] The implementation principle of the flow-controllable water-cooled laser heat dissipation device is that the water cavity 1 can divide the water in the tower mouth 4 (a steel pipe with a diameter of 15 mm or 16 mm) into two tower heads 5 (a steel pipe with a diameter of 8 mm). The water flow of the two tower heads 5 (a steel pipe with a diameter of 8 mm) is controlled by rotating the water outlet adjusting valve 13. When the water outlet hole 12 is completely blocked, there is no flow at the water outlet hole 12. When the water outlet hole 12 is opened, the water outlet hole 12 has water flow, and the flow increases with the increase of the circular hole cross-sectional area of the water outlet hole 12, effectively realizing the controllability of the water flow and improving the heat dissipation efficiency of the laser.

[0061] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
