[0024] like Figure 1-5 As shown, a water-cooled laser power supply proposed by the utility model comprises a laser power supply body 1, a mounting frame 2 and a fixed bottom plate 3, wherein the mounting frame 2 is symmetrically welded to the bottom of both sides of the laser power supply body 1, the bottom of the laser power supply body 1 is an open structure, and the fixed bottom plate 3 is movably mounted on the bottom of the laser power supply body 1;

[0025] The inner cavity wall of the laser power source body 1 is provided with a heat pipe 4, and the heat pipe 4 is in an S-shaped structure. A cooling water tank 5 is installed on the end surface of the laser power source body 1. Both ends of the heat pipe 4 penetrate the cavity wall of the cooling water tank 5 and extend to the inner cavity of the cooling water tank 5. The side wall surface of the cooling water tank 5 is provided with a heat dissipation fin 10, and the inner wall of the heat dissipation fin 10 is provided with a groove 11.

[0026] It should be noted that the side wall of the laser power source body 1 can be connected to the fixed base plate 3 through the mounting frame 2 and the fixing bolts. The heat pipe 4 is in an S-shaped structure and is fixed to the inner wall surface of the laser power source body 1. The coolant in the inner cavity of the cooling water tank 5 is extracted by the circulating water pump 6 and the coolant is injected into the heat pipe 4. The other end of the heat pipe 4 is connected to the top of the cooling water tank 5, so that the coolant can be continuously circulated in the heat pipe 4. The heat generated when the laser power source body 1 is working is transferred to the coolant through the heat pipe 4. The heat in the inner cavity of the laser power source body 1 can be taken away by the circulation of the coolant, so as to realize the water-cooled heat dissipation of the laser power source body 1. By circulating the coolant, the heat can be gathered in the cooling water tank 5. The heat dissipation fins 10 can improve the heat dissipation effect of the coolant. At the same time, the inner cavity of the fin is provided with a groove 11, and the coolant can enter the groove 11, which can increase the contact area between the coolant and the heat dissipation fins 10, thereby improving the heat dissipation effect of the coolant.

[0027] In this embodiment, if Figure 4 As shown, the liquid inlet end of the heat pipe 4 is located at the bottom of the inner cavity of the cooling water tank 5, and the liquid outlet end of the heat pipe 4 is located at the top of the inner cavity of the cooling water tank 5. The liquid inlet end of the heat pipe 4 is connected to a circulating water pump 6, and the circulating water pump 6 is a submersible type.

[0028] It should be noted that the coolant can be extracted by the circulating water pump 6 and injected into the heat pipe 4 , and the other end of the heat pipe 4 re-injects the coolant into the cooling water tank 5 .

[0029] In this embodiment, if Figure 1 As shown, a liquid injection pipe 7 is connected to the top surface of the cooling water tank 5 , an end cap 8 is threadedly connected to the top of the liquid injection pipe 7 , and a liquid level observation window 9 is embedded on the end surface of the cooling water tank 5 .

[0030] It should be noted that the liquid level in the cooling water tank 5 can be observed through the liquid level observation window 9. When the coolant is consumed, the coolant can be replenished in time through the injection pipe 7, and the injection pipe 7 can be closed by the end cover 8.

[0031] In this embodiment, if Figure 1 and Figure 2 As shown, the top surface of the laser power source body 1 is conductively connected to an exhaust port 12, an exhaust fan 13 is installed on the top surface of the exhaust port 12, and the side wall of the laser power source body 1 is conductively connected to an air inlet 14, and a dustproof screen 15 is installed on the surface of the air inlet 14.

[0032] It should be noted that, by matching the exhaust fan 13 and the exhaust port 12, the heat in the inner cavity of the laser power supply body 1 can be extracted. After the hot air in the inner cavity of the laser power supply body 1 is extracted, the inner cavity pressure is reduced, and under the action of negative pressure, the outside air can be sucked into the inner cavity of the laser power supply body 1 through the air inlet 14 to achieve air circulation in the inner cavity of the laser power supply body 1, so as to enhance the heat dissipation effect of the laser power supply body 1, and the dustproof screen 15 can block dust in the air.

[0033] The working principle and use process of the utility model are as follows: the side wall of the laser power source body 1 can be connected to the fixed base plate 3 through the mounting frame 2 and the fixing bolts. The heat pipe 4 is in an S-shaped structure and is fixed to the inner wall surface of the laser power source body 1. The coolant in the inner cavity of the cooling water tank 5 is extracted by the circulating water pump 6, and the coolant is injected into the heat pipe 4. The other end of the heat pipe 4 is connected to the top of the cooling water tank 5, so that the coolant can be continuously circulated in the heat pipe 4. The heat generated by the laser power source body 1 when working is transferred to the coolant through the heat pipe 4. The heat in the inner cavity of the laser power source body 1 can be taken away by the circulation of the coolant. At the same time, the heat in the inner cavity of the laser power source body 1 can be extracted by the exhaust fan 13 and the exhaust port 12. After the hot air in the inner cavity of the laser power source body 1 is extracted, the pressure in the inner cavity is reduced, and under the effect of negative pressure Under this condition, the outside air can be sucked into the inner cavity of the laser power supply body 1 through the air inlet 14 to realize the air circulation of the inner cavity of the laser power supply body 1. At the same time, when the hot air is discharged through the exhaust port 12, the air flow rate on the surface of the heat pipe 4 at the exhaust port 12 can be increased, thereby further improving the heat dissipation effect of the laser power supply body 1. Through the circulation of the coolant, the heat can be gathered in the cooling water tank 5, and the heat dissipation fins 10 can improve the heat dissipation effect of the coolant. At the same time, a groove 11 is opened in the inner cavity of the fin, and the coolant can enter the groove 11, which can increase the contact area between the coolant and the heat dissipation fins 10, thereby improving the heat dissipation effect of the coolant. The liquid level height in the cooling water tank 5 can be penetrated through the liquid level observation window 9. When the coolant is lost, the coolant can be replenished in time through the injection pipe 7, and the injection pipe 7 can be closed through the end cover 8.
