[0040] During operation, fiber lasers require a large amount of circulating cooling water to cool the internal optical and electrical modules. After the laser completes the light output test and the water supply is cut off, a large amount of residual circulating cooling water usually accumulates in the water pipes inside the laser. During the disassembly of water pipes and the machine's movement within the workshop, water will continuously leak onto the floor, causing water accumulation on the workshop floor and posing certain production safety hazards.

[0041] This utility model proposes a circulating water control cabinet to solve the above problems.

[0042] Please see Figures 1 to 2In one embodiment of this utility model, a circulating water control cabinet is proposed, mainly used in the circulating water cooling pipeline of laser 1. During use, due to its high-power characteristics, laser 1 typically generates a large amount of heat internally. To ensure the normal operation of laser 1, its cooling structure (including cooling water channels) generally needs to work in conjunction with a circulating water cooling structure to cool its internal optical and electrical modules. Therefore, when laser 1 is undergoing light emission testing, its internal cooling water channels are usually connected to the circulating water cooling structure. After the light emission test is completed, a large amount of residual circulating cooling water accumulates in the cooling water channels inside laser 1. When laser 1 is disconnected from the circulating water cooling structure, the residual cooling water in laser 1 will flow out, causing water accumulation on the workshop floor, posing a certain production and installation hazard. Considering the above problems, the circulating water control cabinet proposed in this embodiment can promote the discharge of cooling water from inside laser 1 after the laser 1 has completed testing, thereby ensuring that there is no water residue inside laser 1 after testing, thus improving the safety of the entire testing environment. Specifically, during actual testing, the water supply device 2 is connected to the laser 1 via a three-way valve 3 and a return water structure 4, thus achieving a circulating supply of cooling water. Specifically, the output end of the water supply device 2 introduces cooling water from one of the second connection ends of the three-way valve 3, and then flows into the cooling water channel inside the laser 1 through the other second connection end. During this process, both second connection ends are in a conductive state, while the air supply component 51 connected to the first connection end on the three-way valve is in a closed state. The cooling water entering the laser 1 flows back into the water supply device 2 from the two conductive return water connection ends on the first three-way valve 41, thereby achieving circulating cooling of the laser 1 during use. After the laser 1 completes its light emission test, the above structure is needed to facilitate the drainage of water from the internal cooling channels of the laser 1. Specifically, the three-way structure 3 and the first three-way valve 41 need to be adjusted to disconnect the two interconnected second connection ends in the three-way structure, and then connect the first connection end to one of the first connection ends connected to the laser 1. Simultaneously, the two return water connection ends in the first three-way valve 41 are disconnected from each other, and then the return water connection end connected to the laser 1 is connected to the discharge end. After the above adjustments are completed, the air supply component 51 will operate and blow air into the three-way structure at a certain pressure. This creates an airflow from the three-way structure 3 to the laser 1 and from the laser 1 to the drain pipe 52. This airflow facilitates the rapid drainage of residual cooling water inside the laser 1.In actual operation, a water storage structure is connected to the extreme end of the drain pipe 52 to collect the water discharged from the laser 1. After the water in the laser 1 is completely discharged, the laser 1 is disconnected from the second connection end and the return water connection end, thus effectively solving the problem of residual cooling water flowing out of the laser 1. Furthermore, to improve the ease of use of the entire device, the three-way structure 3 and the first three-way valve 41 can be configured as electrically controlled structures, thereby achieving automated control and greatly improving the convenience of using the entire device.

[0043] In this embodiment, the three-way structure 3 is configured to consist of a second three-way valve 31 and a connecting pipe 32. Specifically, the first connecting end and the two second connecting ends correspond to the three ports of the second three-way valve 31. During actual installation, the inlet pipe 321 and the outlet pipe 322 are respectively installed on the two second connecting ends. The other two ends of the inlet pipe 321 and the outlet pipe 322 are respectively connected to the laser 1 and the water supply device 2. When cooling the laser 1, the water supply device 2 introduces cooling water into the second three-way valve 31 through the inlet pipe 321, and then introduces the cooling water into the laser 1 through the outlet pipe 322. It is conceivable that, in addition to the three-way valve structure mentioned above, the three-way structural component 3 also includes the following embodiments. For example, when the production materials only meet the requirements of a single two-way valve structure, a three-way connector can be connected to one end of the two-way valve structure to form the three-way structural component 3 mentioned above. The two-way valve structure can also realize the opening and closing of the water supply passage and meet the above control process. The specific selection can be made according to the actual production materials.

[0044] The gas supply component 51 specifically includes a gas supply device 511 and an air inlet pipe 512. The gas supply device 511 can be configured as an air compressor. One end of the air inlet pipe 512 is connected to the output end of the gas supply device 511. When the gas supply device 511 is working, it introduces high-pressure gas into the second three-way valve 31 through the air inlet pipe 512. In actual use, to prevent cooling water from flowing back into the air inlet pipe 512, a valve assembly 513 is provided on the air inlet pipe 512. Specifically, the valve assembly 513 includes a pilot-operated normally closed two-way valve 5131 and a one-way valve 5132. The one-way valve 5132 allows fluid to move unidirectionally from one end of the pilot-operated normally closed two-way valve 5131 towards the first connection end, thus effectively preventing the cooling water in the laser 1 and the water outlet pipe 322 from flowing back into the air inlet pipe 512. In actual use, the discharge control of high-pressure airflow can be achieved by controlling the energization and de-energization of the pilot-operated normally closed two-way valve 5131, thereby effectively improving the operational convenience of the entire circulating water control cabinet.

[0045] The first three-way valve 41 and the second three-way valve 31 can be configured as the aforementioned electrically controlled valves. Since this design uses a pneumatic output structure, they can be controlled by the air supply device 511, and both three-way valve structures can be configured as pneumatically controlled pneumatic three-way ball valves. In actual use, two connecting air pipes can be branched off from the air supply device 511 and connected to the air inlet structures of the two pneumatic three-way ball valves respectively. The air supply device 511 controls the switching of the internal conduction type of the first three-way valve 41 and the second three-way valve 31. In practice, a manifold 8 is connected to the output end of the air supply device 511. The manifold 8 includes two output ports. One port is connected to the first three-way valve 41 and the second three-way valve 31, controlling the switching of the valves through air supply. The other port is connected to the air inlet pipe 512, facilitating the drainage of residual water from the laser 1.

[0046] Additionally, it is conceivable that corresponding connecting pipes should also be provided at the two return water connection ends of the first three-way valve 41. Specifically, a return water inlet pipe 42 and a return water outlet pipe 43 are connected at the two return water connection ends, and the other ends of the return water inlet pipe 42 and the return water outlet pipe 43 are respectively connected to the laser 1 and the water supply device 2. The cooling water discharged from the internal cooling water channel of the laser 1 flows into the first three-way valve 41 through the return water inlet pipe 42 and into the water supply device 2 through the return water outlet pipe 43, thereby completing the water circulation.

[0047] The entire circulating water control cabinet also includes a housing 6, which supports the relevant piping structure and houses the corresponding valve structure. Specifically, the first three-way valve 41 and the second three-way valve 31 are both located within the housing 6, as are the pilot-operated normally closed two-way valve 5131 and the one-way valve 5132, both of which can be installed inside the housing 6. Furthermore, through holes 61 are provided on opposite side walls in the horizontal direction of the housing 6. Specifically, the inlet pipe 321 and the return water outlet pipe 43 extend outward from one of the through holes 61, while the outlet pipe 322 and the return water inlet pipe 42 extend outward from the other through hole 61. During installation, the extended ends of the corresponding pipes can be connected to the external structure, allowing the housing 6 to provide basic support for the corresponding piping structure.

[0048] To automate the entire device, a control structure is provided on the outer casing 6. This control structure controls the operation of the water supply device 2 and the air supply device 511. Specifically, the structure includes a control board 71, a power indicator light 72, a water switch 73, a drain switch 74, a rocker switch 75, and a power connector 76. The control board 71 processes relevant electrical signals, and the rocker switch 75 controls the operation of the power supply connection. The power indicator light 72 reflects the power-on status of the entire device. When cooling the laser 1, the water switch 73 controls the first three-way valve 41 and the second three-way valve 31 to achieve the aforementioned circulating water flow scheme. When the laser 1 is tested, the drain switch 74 controls the switching of the first three-way valve 41 and the second three-way valve 31 to operate, thereby draining the laser 1.

[0049] In addition, to facilitate the movement of the entire control cabinet structure, multiple casters 62 are provided at the bottom of the outer casing 6, which can facilitate the movement of the entire structure by relevant personnel during actual use.

[0050] This utility model also includes a laser cooling system, which includes a circulating water control cabinet. The specific structure of the circulating water control cabinet is as described in the above embodiments. Since the laser cooling system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
