Description

Technical Field

[0001] This invention relates to the field of liquid pumps, and in particular to a liquid-cooled pump chamber flow channel structure and a liquid-cooled pump, which is mainly but not limited to liquid-cooled pumps for radiators. Background Technology

[0002] Current liquid-cooled heat sinks typically consist of a liquid radiator and a liquid cooling head. A liquid pump drives the liquid circulation within the radiator and cooling head. After absorbing heat on the cooling head, the liquid flows back to the radiator for dissipation, and then returns to the cooling head. The driving performance of the liquid pump directly affects the smoothness and flow rate of the liquid. In practical applications, it is necessary to increase the impeller speed and the overall size of the liquid pump to select a pump with larger operating performance parameters to improve the flow rate. This results in higher costs and energy consumption, and the larger size limits its application scenarios. Therefore, for applications with high size requirements and / or high power consumption requirements, traditional liquid pumps are limited in terms of liquid flow smoothness and flow rate, making it difficult to meet higher performance demands.

[0003] Therefore, the applicant has carefully researched a new technical solution to address the above problems. Summary of the Invention

[0004] In view of this, the present invention addresses the deficiencies of the prior art, and its main objective is to provide a liquid-cooled pump chamber flow channel structure and a liquid-cooled pump, which provides good flow guidance, better smoothness, and helps to improve the working efficiency of the liquid pump.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A liquid-cooled pump chamber flow channel structure includes a liquid pump mounting cavity, with a liquid inlet hole centrally located at the bottom of the liquid pump mounting cavity and a liquid outlet hole located on the circumferential side of the liquid pump mounting cavity; a liquid-blocking boss is protruding on one side of the inner circumferential sidewall of the liquid pump mounting cavity corresponding to the liquid outlet hole, and a flow-guiding groove is recessed on the other side corresponding to the liquid outlet hole; the liquid-blocking boss is arranged in a gradually thinning manner along the rotational circumference of the impeller, and the flow-guiding groove is arranged in a gradually deepening manner along the rotational circumference of the impeller.

[0007] As a preferred embodiment, the first end of the liquid-blocking boss is a concave arc surface. When the liquid rushes to the first end of the liquid-blocking boss, the concave arc surface forms a local swirling and stopping effect, causing the liquid to return to the liquid outlet.

[0008] As a preferred embodiment, the flow guide groove is arranged such that its area in the vertical direction gradually increases along the rotation circumference of the impeller.

[0009] As a preferred embodiment, the cross-section of the flow guiding groove is an arc-shaped groove, a V-shaped groove, or a rectangular groove.

[0010] As a preferred embodiment, the outer periphery of the liquid inlet is provided with an annular wall to form a pressurization chamber.

[0011] As a preferred embodiment, the starting end of the flow guiding groove maintains a distance from the end of the liquid-blocking boss.

[0012] A liquid-cooled pump includes a liquid pump mounting cavity and an impeller installed in the liquid pump mounting cavity. The liquid pump mounting cavity is any of the liquid pump mounting cavities described above. The impeller rotates in the up-down direction. When the impeller rotates, it drives the liquid flow along the liquid-blocking boss and the flow-guiding groove. The liquid flow flows out from the end of the flow-guiding groove and enters the liquid outlet hole, and then flows out from the liquid outlet hole.

[0013] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly involves providing a liquid-blocking boss on one side of the inner circumferential sidewall of the liquid pump mounting cavity corresponding to the liquid outlet hole, and a flow-guiding groove on the other side corresponding to the liquid outlet hole, which plays a good guiding role, improves smoothness, facilitates the increase of flow rate, and helps to improve the working efficiency of the liquid pump; and the first end of the liquid-blocking boss is a concave arc surface. When the liquid rushes to the first end of the liquid-blocking boss, the concave arc surface forms a local swirling stop effect, causing the liquid to return to the liquid outlet hole, ensuring the liquid output of the liquid outlet hole.

[0032] Please refer to Figures 1 to 8 As shown, it illustrates the specific structure of a preferred embodiment of the present invention.

[0033] A liquid-cooled pump chamber flow channel structure includes a liquid pump mounting cavity 32, with a liquid inlet 321 centrally located at the bottom of the liquid pump mounting cavity 32 and a liquid outlet 322 located on the circumferential side of the liquid pump mounting cavity 32. A liquid-blocking boss 323 is protruding on one side of the inner circumferential sidewall of the liquid pump mounting cavity 32, corresponding to the liquid outlet 322, and a flow-guiding groove 324 is recessed on the other side corresponding to the liquid outlet 322. The impeller 41 of the liquid pump rotates in the front-back direction. The liquid-blocking boss 323 is arranged in a gradually thinning manner along the rotation circumference of the impeller 41, and the flow-guiding groove 324 is arranged in a gradually deepening manner along the rotation circumference of the impeller 41. At the same time, the area occupied by the flow-guiding groove 324 in the vertical direction along the rotation circumference of the impeller 41 gradually increases.

[0034] like Figures 1 to 3As shown, the end of the liquid-blocking protrusion 323 extends to the opposite side of the liquid outlet 322, while the starting end of the flow-guiding groove 324 maintains a distance from the end of the liquid-blocking protrusion 323. The liquid rotates along the liquid-blocking protrusion 323, and the liquid-containing space is gradually increased until it reaches its maximum in the area between the end of the liquid-blocking protrusion 323 and the starting end of the flow-guiding groove 324. Starting from the starting end of the flow-guiding groove 324, it is further recessed along the inner circumferential sidewall of the pump mounting cavity 32 within the maximum liquid-containing space. The liquid spirals out along the flow-guiding groove 324. Because the flow-guiding groove 324 is gradually increased in size and depth, it facilitates the rapid flow of liquid to the liquid outlet 322. Preferably, the first end of the liquid-blocking protrusion 323 is a concave arc surface. When the liquid rushes to the first end of the liquid-blocking protrusion 323, the concave arc surface forms a local swirling stop effect, causing the liquid to return to the liquid outlet hole, further ensuring the liquid output of the liquid outlet hole 322.

[0035] like Figure 4 As for Figure 6 As shown, the cross-section of the flow guide groove 324 can be an arc-shaped groove, a V-shaped groove, a rectangular groove, or other shapes, as long as it is recessed into the inner circumferential side wall of the liquid pump mounting cavity 32.

[0036] like Figure 7 and Figure 8 As shown, a liquid-cooled pump includes a liquid pump mounting cavity 3232 and an impeller 41 installed within the liquid pump mounting cavity 3232. The liquid pump mounting cavity 32 is the aforementioned liquid pump mounting cavity 32. The rotation axis of the impeller 41 is vertical. When the impeller 41 rotates, it drives the liquid flow along the liquid-blocking boss 323 and the flow-guiding groove 324. The liquid flow exits from the end of the flow-guiding groove 324 and enters the liquid outlet 322, and then flows out from the liquid outlet 322. Preferably, the outer periphery of the liquid inlet 321 is provided with an annular wall 325 to form a pressurization chamber 326.

[0037] The key design feature of this invention is that a liquid-blocking boss is provided on one side of the inner circumferential sidewall of the liquid pump mounting cavity 32 corresponding to the liquid outlet, and a flow-guiding groove is provided on the other side corresponding to the liquid outlet. This provides good flow guidance, better smoothness, and facilitates the improvement of flow rate, thereby improving the working efficiency of the liquid pump. Furthermore, the first end of the liquid-blocking boss is a concave arc surface. When the liquid rushes to the first end of the liquid-blocking boss, the concave arc surface forms a local swirling and stopping effect, causing the liquid to return to the liquid outlet and ensuring the liquid output of the liquid outlet.
