Description

Technical Field

[0001] This utility model relates to the field of radiator technology, specifically a novel rotating water cooling head. Background Technology

[0002] With the rapid development of electronic devices, high-power processors, new energy motor controllers, and industrial equipment, heat dissipation technology has become one of the core factors restricting equipment performance, reliability, and service life. Traditional liquid cooling systems typically use fixed water cooling heads, relying on water pumps to drive coolant through static water channels, achieving heat exchange through heat conduction and convection.

[0003] Current mainstream water cooling heads adopt a design paradigm that combines topology-optimized flow channels with enhanced heat transfer surfaces, and their thermodynamic performance is approaching the theoretical limit of fixed structures. Especially in asymmetric heat source scenarios such as high-power GPUs, the problem of uneven working fluid distribution caused by the fixed orientation of traditional water cooling heads becomes prominent: when there is an angle between the heat source distribution and the flow channel direction, the flow velocity in local areas can decrease by more than 35%, causing a significant hot spot effect. To solve this problem, the inventors have proposed a novel rotating water cooling head. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-4 As shown, this utility model discloses a novel rotating water cooling head, comprising a housing assembly, a rotating mechanism 20, a water pump mechanism, and a limiting assembly. The rotating mechanism 20 is disposed on the inner side wall of the housing assembly and is used to drive the water cooling head to rotate. The water pump mechanism is disposed on the inner side wall of the housing assembly. The limiting assembly is disposed on the inner side wall of the rotating mechanism 20 and is used to limit the rotating mechanism 20. The rotating mechanism 20 includes a drive motor 21, a rotating plate 23, and a rotating groove 22. The rotating plate 23 is disposed on the upper surface of the limiting assembly, the rotating groove 22 is formed on the inner side wall of the rotating plate 23, and the drive motor 21 is disposed on the inner side wall of the rotating plate 23.

[0020] Specifically, when the equipment is started, the drive motor 21 will drive the fan blades (not shown) to extend and retract up and down, which facilitates further adjustment of the position of the fan blades and improves practicality. The rotating slot 22 facilitates disassembly and assembly when the drive motor 21 is inspected.

[0021] It also includes a movable plate 201, which is located at one end of the limiting component to facilitate the movement of the limiting component and the rotating plate 23 respectively. The movable plate 201 extends inward and has a sliding groove 204 at one end. The movable plate 201 extends outward and has a drive motor 202, which is vertically mounted on the movable plate 201. The drive motor 202 extends outward and has a slider 203, which is located on the inner side wall of the sliding groove 204.

[0022] Specifically, the limiting rod 41 in the limiting assembly is driven by the transmission motor 202 of the moving plate 201, and reciprocates along the sliding groove 204 to dynamically adjust the radial position of the rotating plate 23. The slider 203 of the moving plate 201 cooperates with the sliding groove 204 to realize the synchronous movement of the limiting assembly and the rotating mechanism 20, ensuring the structural stability during the flow channel adjustment process.

[0023] When an angle is detected between the heat source distribution and the flow channel direction, the control system (not shown) drives the transmission motor 202 to operate, causing the slider 203 to move along the sliding groove 204 of the moving plate 201.

[0024] The displacement of slider 203 is transmitted to moving plate 201 via drive motor 202, and drive motor 21 synchronously adjusts the angle of rotating plate 23 so that the flow channel direction is aligned with the high temperature area of ​​heat source.

[0025] The water pump mechanism includes a water pump body 34, a motor 31, and a receiving cavity 32. The water pump body 34 is located on the upper surface of the limiting component, the receiving cavity 32 begins on the inner side wall of the water pump body 34, and the motor 31 is located on the inner side wall of the receiving cavity 32.

[0026] Specifically, the water pump body 34 is driven by the built-in motor 31 to generate the flow power of the coolant. The coolant enters the water pump housing 32 from the inlet pipe 35, and after being pressurized, it enters the internal flow channel of the water cooling head through the outlet pipe 36, forming a basic circulation loop.

[0027] The water pump body 34 extends outward to provide a connecting housing 33, which is located on the upper surface of the water pump body 34. The water pump body 34 extends outward to provide a water inlet pipe 35 for cooling, which is located on one side wall of the water pump body 34. The water pump body 34 has a water outlet pipe 36 corresponding to the water inlet pipe 35 on one side wall for assisting the water inlet pipe 35.

[0028] Specifically, the water pump body 34 forms a multi-layer flow channel with the connecting housing 33 and the outer shell 12. During the axial flow of the coolant, it is diverted through the slots 422 of the inner shell 421, forming three-dimensional turbulence to enhance heat transfer. During the adjustment of the rotating plate 23, the cross-sectional area of ​​the flow channel changes dynamically. Combined with the variable frequency speed regulation of the water pump, the flow velocity distribution of the coolant in the radial section is made uniform, eliminating the local flow velocity attenuation caused by the fixed flow channel in traditional cold heads (the 35% flow velocity loss mentioned in the original question).

[0029] The limiting assembly includes a limiting rod 41, which is located at one end of the rotating plate 23. Multiple limiting rods 41 are provided and spaced apart. The rotating plate 23 is located on the upper surface of the limiting rod 41, and the moving plate 201 is located at one end of the limiting rod 41.

[0030] Specifically, the limit rods 41 are arranged at intervals to form multiple limit intervals, limiting the maximum deflection angle of the rotating plate 23 (e.g., ±30°) and preventing excessive rotation from damaging the flow channel structure.

[0031] It also includes a mounting plate 401 and a placement groove 410. The mounting plate 401 is located at one end of the water pump body 34 to facilitate the limiting of the water pump body 34. The placement groove 410 is opened on the inner side wall of the housing assembly to limit the water pump mechanism. The water pump body 34 is located on the upper surface of the mounting plate 401.

[0032] Specifically, the mounting plate 401 and the slot 422 of the inner shell 421 provide double restraint for the water pump mechanism to prevent displacement caused by vibration or impact. The outer part 11 of the housing assembly and the outer shell 12 fix the water pump body 34 through the placement slot 410, and the spaced slots 422 of the inner shell 421 guide the coolant to be evenly distributed to each flow channel branch to avoid local pressure imbalance.

[0033] It also includes an inner shell 421, which is located on the upper surface of the mounting plate 401 and is used to limit the water pump mechanism. The inner shell 421 extends outward and is provided with slots 422, which are opened on the inner side wall of the inner shell 421. There are multiple slots 422 and they are spaced apart.

[0034] The housing assembly includes an outer part 11 and a housing 12. The housing 12 is disposed on the upper surface of the mounting plate 401, the outer part 11 is disposed at one end of the housing 12, and the placement groove 410 is located on the inner sidewall of the housing 12.

[0035] The rotating mechanism 20 drives the water cooling head to adjust its orientation in real time, so that the cooling channel and the heat source distribution direction are dynamically matched. This solves the problem of uneven working fluid distribution caused by the angle between the channel and the heat source in the fixed cooling head. The drive motor 202 drives the slider 203-sliding groove 204 mechanism to realize the coordinated displacement of the water pump body 34 and the rotating plate 23, which can dynamically adjust the volumetric flow rate and the cross-sectional area of ​​the channel.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
