[0026] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, such as... Figures 1 to 5 The system includes a water-cooled base 1, with a laser array 4 mounted on the top of the base 1 via bolts 5. A water outlet pipe 2 and a water return pipe 3 are installed at the bottom of the base 1. A cooling plate 17 is installed between the water outlet pipe 2 and the water return pipe 3. The cooling plate 17 is installed inside a cooling pool 18, and heat sinks 14 are installed on the outside of the cooling plate 17. The cooling pool 18 has an evaporation zone. The water-cooled base 1 in this invention cools the laser array. The cooling plate 17 is installed inside the cooling pool 18, allowing the cooling pool 18 to cool the cooling plate 17. The heat sinks 14 increase the contact area with the coolant in the cooling pool 18, better protecting the laser array 4 from heat loss and preventing the coolant temperature inside the water-cooled base 1 from rising, thus ensuring good heat dissipation.
[0027] A water pump 16 is installed at the outer end of the water outlet pipe 2. A cooling plate 17 is installed at the other end of the water pump 16 through the dispersion pipe 12. When the water pump 16 is working, the coolant in the water-cooled base 1 enters the cooling plate 17 from the dispersion pipe 12.
[0028] The outer end of the return water pipe 3 is installed at the other end of the cooling plate 17 through the collecting pipe 13. The collecting pipe 13 is used for the coolant in the cooling plate 17 to enter the water-cooled base 1.
[0029] The water-cooled base 1 has connection holes 15 on both sides of the cooling plate 17. The connection holes 15 are used to connect the dispersion pipe 12 and the collection pipe 13.
[0030] The laser array 4 has a square opening at one end. The top and bottom of the square opening are respectively equipped with a laser negative electrode 6 and a laser positive electrode 7. The laser negative electrode 6 is used to connect to the negative terminal of the power supply, and the laser positive electrode 7 is used to connect to the positive terminal of the power supply.
[0031] The negative terminal 8 and the positive terminal 9 of a thermistor are installed on the side of the square opening. The negative terminal 8 and the positive terminal 9 of the thermistor are used to connect to the positive and negative terminals of the power supply, respectively.
[0032] A thermistor 10 and multiple laser units 11 are installed in the middle of the laser array 4. The thermistor 10 is used to stabilize the circuit, and the laser units 11 are used to emit lasers.
[0033] The implementation principle of a high-power, highly integrated water-cooled laser according to an embodiment of this application is as follows: When the high-power, highly integrated water-cooled laser is in use, the laser array 4 is working, and the heat is conducted to the water-cooled base 1. The water pump 16 is working, and the coolant in the water-cooled base 1 enters the dispersion pipe 12 from the outlet pipe 2. After dispersion, it enters the cooling plate 17. The coolant in the cooling pool 18 evaporates, realizing the heat dissipation of the cooling plate 17. The coolant in the cooling plate 17 is entered from the collection pipe 13 into the return water pipe 3 and flows back to the water-cooled base 1, continuously circulating to complete the heat dissipation of the laser array 4.
[0034] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
