[0004] During long-term use, the water-cooled cold head is prone to liquid leakage. Once the cooling water leaks into the laser cavity, a series of problems will occur, such as internal corrosion of the laser, contamination of optical elements, short circuit of the circuit, and failure of thermal management.

Specific embodiments
[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0033] Please refer to Figures 1-8 , the present utility model provides a technical solution:
[0034] A constant temperature circulating cooling water pipeline system for artificial crystal production, including a cold head 1, a cold row 4 and a water pump 5 that are circularly connected through a water outlet pipe 2 and a water inlet pipe 3. Specifically, the water pump 5 works to drive the cooling water to flow through the water outlet pipe 2 and the water inlet pipe 3 to realize the circulating flow of the cooling water between the cold head 1 and the cold row 4. The cold row 4 cooperates with a fan to reduce the temperature of the cooling water. A clamping hole 12 for clamping the crystal 6 is formed on the cold head 1. The heat of the crystal 6 is transferred to the cold head 1 through the inner surface of the clamping hole 12, and then transferred to the cooling water circulating inside the cold head 1.
[0035] In the present invention, the cold head 1 includes chucks 11 symmetrically clamped on both sides of the crystal 6. The two chucks 11 clamp the crystal 6 from both sides to fix the crystal 6. The chuck 11 includes a heat conduction plate 111 in contact with the crystal 6 and a base body hermetically connected to the side of the heat conduction plate 111 away from the crystal 6. In this embodiment, the heat conduction plate 111 can be made of copper material with high thermal conductivity and good heat transfer effect, while the base body can be made of a material with lower thermal conductivity, so as to prevent the heat from the heated cooling water from escaping into the laser cavity later. A water cavity 114 and a buffer cavity 117 surrounding the water cavity 114 are formed between the base body and the heat conduction plate 111. The water cavity 114 and the buffer cavity 117 are relatively independent, that is, the water cavity 114 and the buffer cavity 117 are not connected to each other. The water outlet pipe 2 and the water inlet pipe 3 are both connected to the water cavity 114.
[0036] In the above solution, on the one hand, since the chuck 11 is assembled by the heat conduction plate 111 and the base body, the processing difficulty of the water cavity 114 and the buffer cavity 117 formed therebetween is small. On the other hand, since the water cavity 114 and the buffer cavity 117 are not connected to each other and the buffer cavity 117 surrounds the water cavity 114, even if the cooling water in the water cavity 114 leaks, the leaked cooling water will preferentially enter the inside of the buffer cavity 117 to prevent the leaked cooling water from polluting the laser cavity.
[0037] The base body includes an inner frame 112, an arched plate 113 and an outer frame 116, and the inner frame 112, the arched plate 113 and the outer frame 116 are integrally formed. One end of the inner frame 112 and one end of the outer frame 116 are both hermetically pressed against the side of the heat conduction plate 111 away from the crystal 6. The other end of the inner frame 112 and the other end of the outer frame 116 are both fixedly connected to the arched plate 113. The outer frame 116 surrounds the outside of the inner frame 112. The heat conduction plate 111, the inner frame 112 and the arched plate 113 surround to form the water cavity 114. The heat conduction plate 111, the inner frame 112 and the outer frame 116 surround to form the buffer cavity 117.
[0038] The heat conduction plate 111 in this embodiment includes a flat plate portion 1111 and a raised portion 1112 (or a concave portion) provided in the middle of the flat plate portion 1111. A half hole 121 forming a clamping hole 12 is formed at the raised portion 1112, and the two half holes 121 cooperate to form the clamping hole 12.
[0039] A first sealing gasket 115 is provided between one end of the inner frame 112 and the heat conduction plate 111 to realize the sealed connection between the inner frame 112 and the heat conduction plate 111. A second sealing gasket 118 is provided between one end of the outer frame 116 and the heat conduction plate 111 to realize the sealed connection between the outer frame 116 and the heat conduction plate 111.
[0040] Fastening blocks 14 are fixed on both seat bodies, and the two correspondingly arranged fastening blocks 14 are fixedly connected by bolts 13. Specifically, in this embodiment, four fastening blocks 14 are arranged on each seat body. The fastening blocks arranged on one seat body are fastening blocks 14a, and the fastening blocks arranged on the other seat body are fastening blocks 14b. One fastening block 14a and one fastening block 14b are arranged corresponding to each other vertically, and this fastening block 14a and fastening block 14b are fixedly connected by bolts 13. Further, in this embodiment, the four fastening blocks 14 on the same seat body have the function of defining the position of the heat conduction plate 111 hermetically connected to the seat body, specifically manifested as the four fastening blocks 14 surrounding the heat conduction plate 111 in the middle.
[0041] Positioning angle plates 15 are fixed on the heat conduction plate 111. Four positioning angle plates 15 are arranged in this embodiment. The positioning angle plates 15 are arranged at the corner positions of the buffer cavity 117 and are used to define the relative positions of the heat conduction plate 111 and the seat body.
[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
