Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chip cooling, and particularly relates to a liquid cooling radiator device. Background Art
[0002] With the rapid development of computer technology, the performance of processors has been continuously improved, and their heat dissipation requirements have increased sharply accordingly. The traditional air-cooled heat dissipation system has poor heat dissipation effect when facing high-performance CPUs. Therefore, the liquid cooling heat dissipation technology is widely used in high-performance CPUs due to its excellent heat dissipation effect.
[0003] However, there are still many problems to be solved urgently in the current liquid cooling radiators on the market. Firstly, the heat dissipation efficiency is insufficient, which is mainly manifested in that the coolant cannot fully absorb the heat of the CPU, and the uneven distribution of the coolant affects the heat dissipation effect and the stable operation of the CPU. Secondly, there are defects in the design of the water-cooling pump head. The unreasonable layout of the inlet and outlet water ports is easy to cause water flow short circuit, further reducing the coolant circulation efficiency and the overall heat dissipation performance. At the same time, this design defect often leads to obvious noise generated by the radiator during high-speed operation, affecting the user experience. In addition, in order to improve the efficiency, some liquid cooling radiators adopt complex internal structures. Although the heat dissipation effect is improved to a certain extent, the manufacturing cost and maintenance difficulty are also significantly increased, which is not conducive to the large-scale application and long-term use of the products. These problems seriously restrict the popularization of the liquid cooling heat dissipation technology in high-performance computing devices, and there is an urgent need for an innovative design that can improve the heat dissipation efficiency, reduce the operating noise, and simplify the structure at the same time. Summary of the Utility Model

[0005] To achieve the above object, the utility model provides the following technical solutions.

[0024] The following further elaborates and explains the solution of the present utility model in conjunction with specific embodiments and the accompanying drawings. Specific embodiments
[0026] Please refer to Figures 1 to 4 , the present utility model provides a liquid-cooled radiator device, which includes a water-cooling pump head 1, a radiator 2 and a connecting pipe 3. The structure of the water-cooling pump head 1 includes a housing 11, a partition plate 12 disposed inside the housing 11, and a bottom plate 13 connected to the bottom of the housing 11. An inlet channel 14 and an outlet channel 15 are formed between the housing 11 and the pipe 3.
[0027] The peripheral side of the partition plate 12 is in close contact with the cavity wall of the housing 11, and divides the internal space of the housing 11 into an upper first hollow cavity and a lower second hollow cavity. The inlet channel 14 opens downward and directly communicates with the lower second hollow cavity through a first notch 121 provided on the partition plate 12. The opening of the outlet channel 15 communicates with the upper first hollow cavity.
[0028] In addition to the first notch 121, the partition plate 12 is also provided with a second notch 122 for communicating the first hollow cavity and the second hollow cavity. During operation, the flow path of the coolant is that the coolant enters the second hollow cavity from the inlet channel 14, fully contacts the bottom plate 13, then rises into the first hollow cavity through the second notch 122, and finally is discharged from the outlet channel 15. This structural design optimizes the flow path of the coolant and prolongs the residence time of the coolant in the water-cooling pump head. In addition, the separated design of the inlet and outlet channels effectively prevents the short circuit of the cold and hot flows and improves the overall heat dissipation efficiency.
[0029] In an embodiment of the present utility model, a fin array 131 is provided on the upper surface of the bottom plate 13. The fin array 131 is composed of a plurality of fins perpendicular to the surface of the bottom plate 13, and these fins are arranged in parallel to form a series of uniformly distributed heat dissipation units. The advantage of this structure is that the fin array 131 increases the contact area between the bottom plate 13 and the coolant and improves the heat transfer efficiency; in addition, the design of the fin array 131 can enhance the structural strength of the bottom plate 13 and improve the overall durability.
[0030] In an embodiment of the present utility model, a water distribution plate 16 and a sealing plate 17 are further added between the bottom plate 13 and the isolation plate 12. These two components are arranged in sequence from bottom to top, forming a composite water flow control system. Specifically, the bottom of the water distribution plate 16 abuts against the fin array 131 on the bottom plate 13, and the sealing plate 17 covers and seals above the water distribution plate 16. At least one first through hole 181 is provided on the water distribution plate 16, and at least one second through hole 191 is correspondingly provided on the sealing plate 17. The first through hole 181 and the second through hole 191 communicate with each other, forming a directional flow path for the coolant. The layered design of the water distribution plate 16 and the sealing plate 17 realizes the precise control of the coolant flow, ensuring that the liquid evenly flows through each part of the fin array 131 and avoiding local overheating phenomena.
[0031] In an embodiment of the present utility model, the design of the sealing plate 17 is further optimized, and its lower surface has an integrally formed concave structure. The function of this concave structure is to accommodate the water distribution plate 16, that is, the water distribution plate 16 is built into the concave structure. The precise fit between the concave structure and the water distribution plate 16 improves the structural stability of the entire assembly and reduces the possible shaking or displacement during use.
[0032] In an embodiment of the present utility model, the first through holes 181 on the water distribution plate 16 and the second through holes 191 on the sealing plate 17 correspond to each other and have the same shape. The design of through holes with the same shape is to enable the coolant to maintain a stable flow path when flowing through the water distribution plate 16 and the sealing plate 17, reducing the pressure loss that may be caused by the change in aperture. At the same time, the through holes with the same shape can also simplify the manufacturing process and facilitate production and processing.
[0033] In an embodiment of the present utility model, to further improve the structure of the water-cooled pump head 1, a receiving cavity 111 is provided on the upper surface of the housing 11, and an installation hole is provided at the center position of the receiving cavity 111. A stator assembly 4 and a rotor assembly 5 are added. Among them, the stator assembly 4 is fixedly installed in the installation hole on the upper surface of the housing 11. Installing the stator assembly 4 in the installation hole ensures its stable operation and provides a power source for the rotor assembly 5. By embedding the stator assembly 4 into the installation hole, the volume of the entire water-cooled pump head 1 can also be reduced, making the structure more compact.
[0034] In an embodiment of the present utility model, the rotor assembly 5 adopts a modular design, including a rotatable part 51 and an impeller part 52 that are detachably connected. The rotatable part 51 is arranged in the receiving cavity 111 on the upper surface of the housing 11, and the impeller part 52 is arranged in the first hollow cavity. The detachable structural design is convenient for installation and maintenance and extends the service life of the equipment. The impeller part 52 is arranged in the first hollow cavity and is in direct contact with the coolant, which can effectively promote the coolant circulation and is also beneficial for reducing vibration and noise.
[0035] In an embodiment of the present utility model, the impeller part 52 includes a disc-shaped main body, on which a plurality of spiral blades are arranged. The spiral blades extend in a curved shape from the central position of the impeller part 52 towards the periphery. Circular through-holes are provided between adjacent blades. The design of the circular through-holes can reduce the resistance of the blades to the liquid, and at the same time can also balance the pressure on both sides of the impeller, which helps to reduce the axial thrust of the impeller and extend the service life of the equipment.
[0036] In an embodiment of the present utility model, the design of the impeller part 52 is further optimized. Specifically, a circular through-hole is provided between every two adjacent spiral blades, and the number of circular through-holes is equal to the number of spiral blades. This one-to-one corresponding design ensures the symmetry and balance of the impeller structure.
[0037] In an embodiment of the present utility model, two fans 6 are arranged on the heat dissipation row 2.
[0038] The above has introduced in detail a liquid-cooled radiator device provided by the present utility model. Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea and method of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
