Description

Technical Field

[0001] This utility model relates to the field of water cooling technology, specifically to a water distribution device for water-cooled radio frequency lasers. Background Technology

[0002] During operation, water-cooled radio frequency lasers continuously generate heat in their circuit components (such as the radio frequency drive module) and optical components (such as the laser resonator). If the heat cannot be dissipated in a timely and uniform manner, it will cause fluctuations in the laser's operating temperature, which in turn will affect the stability of the laser output power, the beam quality, and even shorten the service life of the core components.

[0003] Currently, existing water distribution devices for water-cooled radio frequency lasers often have the following problems: First, the water distribution structure is unreasonable, often consisting of a one-to-two or asymmetrical one-to-many structure. Such a design makes it difficult to simultaneously meet the heat dissipation requirements of multiple circuit and optical components. Second, the water pipe diameters of the multiple water outlet interfaces are inconsistent, resulting in large differences in water flow rate in each branch, causing excessive heat dissipation in some areas and insufficient heat dissipation in others, resulting in poor heat dissipation uniformity.

[0022] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] like Figures 1-4The water distribution device shown is used in a water-cooled radio frequency laser. It includes a water distribution device body, on which are provided an inlet port 1, a first outlet port 2, a second outlet port 3, a third outlet port 4, a flow channel 6, and a sealing port 7. The inlet port 1 communicates with the flow channel 6. Two flow channels 6 are symmetrically arranged. The flow channels 6 are machined by CNC drilling, with identical inner diameters. The length deviation between the two flow channels 6 is ≤0.2mm to ensure balanced flow of the three water channels and to assist in pipe avoidance. The flow channel 6 communicates with the first outlet port 2, the second outlet port 3, the third outlet port 4, and the sealing port 7. The first outlet port 2 and the third outlet port 4 are symmetrically positioned, as are the second outlet port 3 and the third outlet port 4. The diameters of the first outlet port 2, the second outlet port 3, and the third outlet port 4 are the same. The inlet ports 1 are arranged in pairs and symmetrically. The inlet ports 1 are threaded interfaces with thread precision conforming to GB / T standards. According to the 197 standard, the water inlet interface 1 is used to connect to the external main water supply pipeline to realize water input. It is installed in conjunction with the sealing interface 7 through the sealing element to seal the internal flow channel.

[0024] The aforementioned water distribution device for water-cooled RF lasers is designed with an inlet 1 connected to a flow channel 6, which in turn connects to the first outlet 2, the second outlet 3, and the third outlet 4. The first and third outlets 2 and 3 are symmetrically positioned, forming a symmetrical one-to-three water distribution structure. The three outlets can be connected to the circuitry (e.g., RF driver board) and optical components (e.g., resonant cavity lenses, laser modules) of the water-cooled RF laser, respectively, enabling synchronous heat dissipation across multiple areas and meeting the complex heat dissipation requirements of the laser. Furthermore, the first, second, and third outlets 2 and 3 have the same diameter, and all three outlets are compatible with water pipes of the same specifications. The symmetrical arrangement of the flow channels 6 ensures consistent water flow resistance, guaranteeing a flow rate deviation of ≤5% for the three outlets. This effectively prevents localized overheating or insufficient heat dissipation, ensuring uniform heat dissipation and stable laser operating temperature.

[0025] like Figures 1-3 As shown in this embodiment, the water distribution device body is also provided with fixing holes 5, which are through holes. The tolerance of the un-filled holes of the water distribution device is designed according to positive tolerance, and the shaft tolerance is designed according to negative tolerance. All tolerances are taken according to the IT13 level of the GB / T1184 standard to ensure assembly accuracy and interface sealing. By setting standardized fixing holes 5 and assembly holes, and with the IT13 level tolerance design, the assembly accuracy is high and the interface sealing is good, which can effectively avoid the risk of water leakage. It solves the problems that the existing water distribution devices are mostly made of metal, which are heavy and easily corroded. Moreover, the assembly tolerance is not standardized, which can easily lead to interface leakage or assembly difficulties. A total of four fixing holes 5 are provided, which are used to connect with bolt fasteners to fix the water distribution device at the designated installation position of the water-cooled radio frequency laser.

[0026] like Figures 1-3 As shown, in this embodiment, two first water outlet ports 2 are symmetrically opened on the main body of the water distribution device; two second water outlet ports 3 are symmetrically opened on the main body of the water distribution device; and two third water outlet ports 4 are symmetrically opened on the main body of the water distribution device. Through symmetrical arrangement, a symmetrical one-to-three water distribution structure is formed. The three water outlets can be connected to the circuit part (such as the radio frequency driver board) and the optical part (such as the resonant cavity lens and the laser module) of the water-cooled radio frequency laser respectively, so as to realize multi-region synchronous heat dissipation and adapt to the complex heat dissipation requirements of the laser.

[0027] like Figure 1 As shown in this embodiment, the cross-section of the water distribution device body is a rounded rectangle; the water distribution device body is integrally injection molded, and the water distribution device body is injection molded from nylon (black) material, which combines lightweight (low single-piece weight), corrosion resistance (adaptable to coolant environment) and structural strength.

[0028] like Figures 1-3 As shown, in this embodiment, the water inlet 1, the first water outlet 2, the second water outlet 3, and the third water outlet 4 are in parallel positions; the sealing interface 7 is perpendicular to the water inlet 1; the water inlet 1 and the first water outlet 2 are located on one side of the water distribution device body, and the second water outlet 3 and the third water outlet 4 are located on the other side of the water distribution device body. The parallel positions of the water inlet 1, the first water outlet 2, the second water outlet 3, and the third water outlet 4 can satisfy the requirement that the coolant flows through the flow channel 6 and that the flow rate of the three water flows is balanced.

[0029] like Figures 1-3 As shown, in this embodiment, the diameter of the water inlet 1 is 10mm, and the diameters of the first water outlet 2, the second water outlet 3, and the third water outlet 4 are all 6mm. By controlling the diameter of the water inlet 1 to be larger than the diameters of the first water outlet 2, the second water outlet 3, and the third water outlet 4, the basic flow conditions of the coolant are met. At the same time, it also allows the three water outlets to be adapted to water pipes of the same specification, and the flow channels 6 are symmetrically arranged, with consistent water flow resistance, ensuring that the flow rate deviation of the three water outlets is ≤5%, effectively avoiding local overheating or insufficient heat dissipation, ensuring uniform heat dissipation, and ensuring stable laser operating temperature.

[0030] like Figures 1-3As shown, in this embodiment, the water distribution device is fixedly installed on the heat dissipation bracket of the water-cooled RF laser through the fixing hole 5 and the corresponding specification bolt fasteners, ensuring that the interface orientation is consistent with the water path. The water inlet 1 is connected to the external coolant supply pipe, and the first water outlet 2, the second water outlet 3, and the third water outlet 4 are respectively connected to the water cooling channel of the RF driver board, the water cooling jacket of the resonant cavity lens, and the water cooling cavity of the laser module through water pipes. The coolant circulation system is started, and the coolant enters the water distribution device body from the water inlet 1, and is evenly distributed to the first water outlet 2, the second water outlet 3, and the third water outlet 4 through the flow channel 6, respectively to dissipate heat from the circuit and optical parts. The temperature is monitored and displayed by the temperature sensor, and the temperature deviation of each heat dissipation area is ≤2℃, and the heat dissipation uniformity is significantly better than that of the existing device. The overall size and interface specifications of the water distribution device conform to the industry general standard and can be adapted to various models of water-cooled RF lasers without additional customization, thus reducing application costs.

[0031] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
