Description

Technical Field

[0001] This utility model relates to the technical field of cooling devices, and more particularly to a cooling device and a laser device. Background Technology

[0002] With the development of technology, lasers are devices that convert electrical energy, chemical energy, or light energy into light energy. Utilizing the principle of stimulated emission, they generate highly concentrated, monochromatic, and directional beams. Cooling devices, as part of the laser equipment, are used to cool the laser.

When the ambient temperature fluctuates, the performance of the optical and electronic components inside the laser changes, leading to unstable laser output power, decreased beam quality, and directional deviation. The lack of a uniform constant temperature environment results in poor cooling performance from existing cooling devices. Utility Model Content

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0026] Please refer to the attached document. Figures 1-7 This application provides a cooling device 100, which is applied to a laser device and is used to perform fully enclosed constant temperature cooling of the laser.

[0027] Please refer to the attached document. Figures 1-7 In this embodiment, a cooling device 100 includes a plurality of cooling plates 10 arranged in different directions, interconnected, and forming a cooling box. Each cooling plate 10 has a receiving cavity 10a for accommodating a laser, which is then fixed to the inner side of the cooling plates 10. The cooling plates 10 are positioned in different directions relative to the laser.

[0028] Each cooling plate 10 is provided with a cooling channel 10b, and multiple cooling channels 10b are interconnected to form a closed loop. Each cooling plate 10 is provided with a first liquid inlet 10c and a first liquid outlet 10d, which are located at different positions on the cooling plate 10. Each cooling plate 10 forms a closed loop. The first liquid inlet 10c and the first liquid outlet 10d are connected to the closed loop. The closed loop is used for the flow of cooling medium, so that the cooling medium can flow into the closed loop through the first liquid inlet 10c. When the cooling medium needs to be discharged, the cooling medium in the closed loop is discharged to the external environment through the first liquid outlet 10d. At this time, multiple cooling plates 10 have cooling medium and provide overall cooling for the laser in the receiving cavity 10a, so as to achieve a fully enclosed constant temperature environment for the laser, effectively reduce the directional deviation of the laser caused by temperature fluctuations, and improve the cooling effect of the cooling device 100.

The cooling medium output from the output end of the first water chiller 20 flows along a closed-loop channel, so that the cooling medium output from the output end of the first water chiller 20 flows into the closed-loop channel through the first liquid inlet 10c. The cooling medium passes through multiple cooling plates 10 to cool the laser in the containment cavity 10a in an overall manner along different directions. This facilitates the cooling of each surface of the laser by multiple cooling plates 10, thereby achieving a fully enclosed constant temperature environment for the laser, effectively reducing the directional deviation of the laser caused by temperature fluctuations, and improving the cooling effect of the cooling device 100.

The first flow channel 12a connects the first liquid inlet 10c and the first liquid outlet 10d so that the cooling medium in the first liquid inlet 10c can flow through the first flow channel 12a to the first liquid outlet 10d, thereby facilitating the discharge of the cooling medium from the first liquid outlet 10d.

The upper cooling plate 15 is provided with a third flow channel 15a, so that the upper cooling plate 15 can store the cooling medium through the third flow channel 15a, thereby facilitating the cooling of the upper side wall of the laser by the upper cooling plate 15. The front cooling plate 11 is provided with a fourth flow channel 11a, so that the front cooling plate 11 can store the cooling medium through the fourth flow channel 11a, thereby facilitating the cooling of the front side wall of the laser by the front cooling plate 11.

[0034] The rear cooling plate 12 is also provided with a second liquid inlet 12b, which is located above or below the first liquid inlet 10c, so that the second liquid inlet 12b and the first liquid inlet 10c can be arranged separately. The second liquid inlet 12b is connected to the second flow channel 13a; the second flow channel 13a is connected to the third flow channel 15a in the upward direction; the second flow channel 13a is connected to the fourth flow channel 11a in the horizontal direction. At this time, the cooling medium input through the second liquid inlet 12b passes through the second flow channel 13a and flows to the third flow channel 15a and the fourth flow channel 11a at the same time, so that the cooling medium is arranged relative to the second flow channel 13a, the third flow channel 15a and the fourth flow channel 11a respectively.

[0036] The fourth flow channel 11a is connected to the fifth flow channel 14a in the horizontal direction; the fifth flow channel 14a is connected to the sixth flow channel 16a in the downward direction. At this time, the cooling medium input through the fourth flow channel 11a passes through the fifth flow channel 14a and flows to the sixth flow channel 16a at the same time, so as to realize that the cooling medium is arranged relative to the fifth flow channel 14a and the sixth flow channel 16a respectively.

[0037] Please refer to the attached document. Figure 1 and 6 In this embodiment of the application, the third flow channel 15a is provided with a plurality of first sub-flow channels 15b, which are arranged along the width direction of the upper cooling plate 15, and two adjacent first sub-flow channels 15b are in a connected state; the plurality of first sub-flow channels 15b extend along the length direction of the upper cooling plate 15; the plurality of first sub-flow channels 15b are arranged in an array, and by arranging a plurality of first sub-flow channels 15b, the arrangement range of the third flow channel 15a relative to the upper cooling plate 15 is increased, thereby improving the cooling range of the upper cooling plate 15.

[0038] Please refer to the attached document.

Figure 1 and 3 In this embodiment, the rear cooling plate 12 is provided with a through hole 12c, which connects to the receiving cavity 10a and exposes the third liquid inlet and the third liquid outlet of the laser, thereby preventing the rear cooling plate 12 from interfering with the third liquid inlet and the third liquid outlet of the laser. The third liquid inlet of the laser is connected to the external second water chiller, so that the cooling medium output by the external second water chiller can flow into the laser through the third liquid inlet of the laser. When the cooling medium in the laser needs to be discharged, the cooling medium in the laser is discharged to the external environment through the third liquid outlet.
