Thus, semiconductor lasers provide a light source basis for direct semiconductor laser devices and high-performance high-power fiber lasers.

[0003] In order to obtain high-power output and meet good heat dissipation requirements at the same time, most of the water-cooled plates currently used in semiconductor laser tests are serpentine flow channel water-cooled plates with the same diameter of the inlet and outlet. There are also some water-cooled plates with a double-inlet and double-outlet flow channel structure to increase the contact area between the cooling water and the device to improve the heat dissipation capacity. With the increase in the power of semiconductor lasers, the traditional serpentine water-cooled plate has limited heat dissipation capacity when dissipating heat from the device. To further optimize the heat dissipation capacity, how to optimize the heat dissipation structure of the water-cooled plate and improve the heat dissipation capacity has become the focus of research. Therefore, an efficient heat-dissipating water-cooled plate is proposed to solve the above problems. Summary of the Invention

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0039] See also Figures 1-5 The present invention discloses a high-efficiency heat dissipation water cooling plate, comprising:

[0040] A plate body 1, wherein a flow channel 11 is provided in the plate body 1. The plate body 1 is a water-cooled plate, and the flow channel 11 provided inside the plate body takes away the heat generated by the components on the plate body, thereby achieving the purpose of cooling and heat dissipation;

[0041] The heat dissipation part 2 is arranged at the bottom of the plate body 1. Specifically, the heat dissipation part 2 is composed of a plurality of heat dissipation fins equidistantly arranged at the bottom of the plate body 1;

[0042] The air cooling part 3 is arranged at one side of the heat dissipation part 2 to improve the heat dissipation efficiency of the heat dissipation part 2. It should be noted that the heat dissipation fins are arranged perpendicular to the air cooling part 3. The airflow generated by the air cooling part 3 drives the airflow in the heat dissipation fins to flow, thereby achieving rapid heat dissipation and cooling;

[0043] A liquid supply portion 4, wherein the liquid supply portion 4 is disposed on the plate body 1 and communicated with the flow channel 11;

[0044] The liquid supply part 4 includes a liquid inlet pipe, an inner magnetic ring 41 is movably provided on the inner wall of the liquid inlet pipe, a driven blade 42 is provided inside the inner magnetic ring 41, an outer magnetic ring 43 corresponding to the inner magnetic ring 41 is sleeved on the outside of the liquid inlet pipe, and the outer magnetic ring 43 is transmission-connected with the air-cooling part 3 to drive the inner magnetic ring 41 to rotate through the driven blades 42 when the liquid flows inside the flow channel 11, thereby driving the outer magnetic ring 43 and the air-cooling part 3 to operate.

[0045] Through the above-mentioned structural arrangement, when the equipment is in use, the cooling medium in the internal flow channel 11 of the plate body 1 continuously circulates, taking away the heat on the plate body 1 to achieve the purpose of cooling. In order to further improve the heat dissipation efficiency, a heat dissipation part 2 is also provided on the plate body 1 to increase the contact area with the air through the heat dissipation fins to improve the heat dissipation efficiency. At the same time, an inner magnetic ring 41 and an outer magnetic ring 43 are provided on the liquid supply part 4, and the outer magnetic ring 43 is transmission-connected with the air cooling part 3. The present application realizes the operation of the external air cooling part 3 by the circulation of the cooling medium to achieve the purpose of synchronous heat dissipation and temperature reduction inside and outside, optimize the heat dissipation structure of the water-cooled plate, and improve the heat dissipation capacity.

[0046] It should be noted that a limiting rotation groove corresponding to the inner magnetic ring 41 is formed in the liquid supply part 4, and the inner magnetic ring 41 is rotatably arranged in the limiting rotation groove. It is easy to think that the inner magnetic ring 41 is fixedly connected to the driven blade 42, so that when the cooling medium passes through the driven blade 42, the inner magnetic ring 41 can be driven to rotate inside the liquid supply part 4.

[0047] In a further embodiment, a plurality of groups of magnets evenly distributed around the axis of the inner magnetic ring 41 are arranged on the inner magnetic ring 41;

[0048] Magnets corresponding to the magnetic induction blocks on the inner magnetic ring 41 are arranged in the outer magnetic ring 43;

[0049] The magnets arranged in the inner magnetic ring 41 and the outer magnetic ring 43 attract each other.

[0050] Through the above structural arrangement, the inner magnetic ring 41 and the outer magnetic ring 43 form a magnetic coupling, and the above structure can be used to drive the external air cooling part 3 to operate and cool down through the magnetic coupling when the cooling medium is running normally.

[0051] It should be further noted that the outer magnetic ring 43 is sleeved outside the liquid inlet pipe, and a connecting bearing is arranged between the liquid inlet pipe and the outer magnetic ring 43. The arrangement of the connecting bearing can effectively reduce the friction between the outer magnetic ring 43 and the liquid inlet pipe and improve the transmission efficiency.

[0052] Preferably, the air cooling part 3 includes a diversion housing 31 and a heat dissipation fan 32 arranged on the diversion housing 31;

[0053] A diversion part is arranged inside the diversion housing 31, the output end of the heat dissipation fan 32 is communicated with the diversion part, and the diversion part is used to disperse the air flow generated by the heat dissipation fan 32 to the heat dissipation part 2.

[0054] It is easy to think that a driven wheel is arranged at the input end of the heat dissipation fan 32;

[0055] A transmission belt 44 is connected between the outer magnetic ring 43 and the driven wheel;

[0056] A limiting groove corresponding to the transmission belt 44 is formed on the outer magnetic ring 43.

[0057] Through the above structural arrangement, during the circulation of the cooling medium in the flow channel 11, the inner magnetic ring 41 can be driven to rotate by the driven blade 42. Also, due to the magnetic connection between the inner magnetic ring 41 and the outer magnetic ring 43, the outer magnetic ring 43 can be driven to rotate synchronously. Then, the heat dissipation fan 32 is driven to rotate through the transmission belt 44, and the air inside the heat dissipation part 2 is driven to flow through the heat dissipation fan 32, improving the heat dissipation efficiency.

[0058] Such as Figures 2-3As shown, the flow channel 11 is a serpentine flow channel evenly distributed within the plate body 1.

[0059] Furthermore, it should be noted that a conical inlet is provided at the inlet end of the liquid inlet pipe to increase the flow rate of the cooling medium after it enters the flow channel 11.

[0060] Furthermore, it also includes a liquid supply part communicated with the liquid inlet pipe;

[0061] A temperature monitoring unit 12 is also provided on the plate body 1. The temperature monitoring unit 12 is used to detect the surface temperature of the plate body 1. A controller is provided in the liquid supply part, and the controller is used to adjust the flow rate of the cooling medium according to the feedback of the temperature monitoring unit 12.

[0062] Through the above structural settings, the device can control the internal flow rate of the plate body 1 according to the temperature of the cooling plate, improving the heat exchange efficiency. Correspondingly, when the internal flow rate of the plate body 1 is increased, the heat dissipation efficiency of the air-cooling part 3 at its bottom will also be further increased, effectively improving the heat dissipation efficiency of the device.

[0063] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, then such directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0064] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present invention, then such descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first", "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement it. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0065] In addition, "a plurality" means more than two.

[0066] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
