[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It will be appreciated that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some but not all structures related to the present application are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the art without making creative work are within the scope of protection of the present application.

[0024] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] See also Figures 1 to 3 , Figure 1 is a schematic diagram of the assembly structure of the water-cooled radiator provided in this application, Figure 2 yes Figure 1 Schematic diagram of the exploded structure of the water cooling radiator in the figure. Figure 3 yes Figure 1 Schematic diagram of the three-dimensional structure of the base in the present application. The present application provides a water-cooled radiator 100, which includes a base 10, a turbine 30 and a heat dissipation bottom cover 50. The base 10 is provided with a cavity 21 for the flow of coolant, and the cavity 21 includes a liquid inlet 211, a liquid outlet 213 and a central cavity 212. The liquid inlet 211 and the liquid outlet 213 are isolated from each other, and the central cavity 212 is connected to the liquid outlet 213. The turbine 30 is assembled in the base 10 and is rotatably connected to the base 10 to accelerate the flow of coolant. The heat dissipation bottom cover 50 covers the cavity 21, and the heat dissipation bottom cover 50 connects the liquid inlet 211 and the central cavity 212. Among them, the coolant entering the liquid inlet 211 enters the central cavity 212 through the heat dissipation bottom cover 50, and the turbine 30 arranged in the central cavity 212 is used to accelerate the flow of coolant to the liquid outlet 213 and discharge the water-cooled radiator 100.

[0026] Specifically, the heat dissipation bottom cover 50 contacts the heat source and conducts heat to absorb the heat generated by the heat source. The coolant in the base 10 contacts the heat dissipation bottom cover 50 to exchange heat with the heat dissipation bottom cover 50 and absorb the heat of the heat dissipation bottom cover 50. By setting a coolant that can flow in the cavity 21, the flowing coolant can be used to continuously take away the heat of the heat dissipation bottom cover 50 to improve the heat dissipation efficiency of the heat dissipation bottom cover 50. By setting a turbine 30 in the cavity 21 to accelerate the flow of the coolant, the heat dissipation efficiency of the heat dissipation bottom cover 50 can be further improved, and the heat dissipation efficiency of the heat source can be improved.

[0027] Alternatively, the heat source may be a computer's CPU (central processing unit). The CPU is located inside the computer and is one of the main devices of the electronic computer and a core component of the computer. As the computing and control core of the computer system, it is the final execution unit for information processing and program operation. As the processing power of the computer system increases, the CPU's computing speed becomes faster and faster, which will cause the CPU to generate more and more heat. When the heat generated by the CPU cannot be dissipated in time, it is not only prone to damage, but also affects the CPU's computing and processing capabilities, thereby reducing the performance of the computer.

[0028] Therefore, the heat dissipation bottom cover 50 of the water-cooled radiator 100 can be brought into contact with the CPU, so as to utilize the water-cooled radiator 100 to dissipate heat from the CPU, thereby enhancing the heat dissipation capacity of the CPU, avoiding damage to the CPU, and facilitating the improvement of the computer's operating performance. The heat dissipation bottom cover 50 can be brought into direct contact with the CPU to improve the heat conduction efficiency and facilitate the rapid diffusion of the heat generated by the CPU. Alternatively, the heat dissipation bottom cover 50 can also be brought into indirect contact with the CPU through other heat-conducting elements, which is not specifically limited in the embodiments of the present application.

[0029] It can be understood that in other embodiments, the heat source may also be electronic devices such as chips, circuit boards, speakers, etc., so that the water-cooled radiator 100 in this embodiment can be used to dissipate heat for the above-mentioned electronic devices.

[0030] The base 10 , the turbine 30 and the heat dissipation bottom cover 50 will be described in detail below one by one.

[0031] See also Figures 1 to 3 The base 10 includes a cavity bottom wall 11, an annular cavity side wall 12, a spiral wall 13, and a partition wall 14 arranged on the cavity bottom wall 11, wherein the annular cavity side wall 12 is annular, and the spiral wall 13 is spiral. That is, the orthographic projection of the annular cavity side wall 12 on the cavity bottom wall 11 is annular, and the orthographic projection of the spiral wall 13 on the cavity bottom wall 11 is spiral. For example, the orthographic projection of the annular cavity side wall 12 can be a circular ring, an elliptical ring, a rectangular ring, etc.

[0032] The first end of the spiral wall 13 is connected to the annular cavity side wall 12 to form a closed port, the second end of the spiral wall 13 spirally extends and is disposed adjacent to the annular cavity side wall 12, the second end of the spiral wall 13 is spaced from the annular cavity side wall 12 to form an opening, and the opening connects the central cavity 212 and the liquid outlet 213. The partition wall 14 is connected to the outer surface of the annular cavity side wall 12 and the spiral wall 13 to separate the liquid inlet 211 and the liquid outlet 213.

[0033] Specifically, the liquid inlet 211 is composed of the annular cavity side wall 12, the outer surface of the spiral wall 13, the first surface of the partition wall 14, and the cavity bottom wall 11; the central cavity 212 is composed of the cavity bottom wall 11 and the inner surface of the spiral wall 13; the liquid outlet 213 is composed of the cavity bottom wall 11, the outer surface of the spiral wall 13, the second surface of the partition wall 14, and the annular cavity side wall 12. The first surface and the second surface of the partition wall 14 are two surfaces arranged opposite to each other.

[0034] It can be understood that in another embodiment, the first end of the spiral wall 13 can also be connected to the annular cavity side wall 12 to form a closed port, the second end of the spiral wall 13 spirally extends and is arranged adjacent to the first end of the spiral wall 13, and the second end of the spiral wall 13 is spaced from the first end of the spiral wall 13 to form an opening, and the opening connects the central cavity 212 and the liquid outlet 213. The partition wall 14 is connected to the outer surface of the annular cavity side wall 12 and the spiral wall 13 to separate the liquid inlet 211 and the liquid outlet 213.

[0035] Furthermore, if Figure 3 As shown, the bottom wall 11 of the central cavity 212 is recessed in a direction away from the spiral wall 13 to form a first annular cavity 217 and a second annular cavity 218, and the first annular cavity 217 and the second annular cavity 218 are arranged around the center of the central cavity 212 at intervals to form a rotating shaft 15 and an annular boss 16 surrounding the rotating shaft 15 at the center of the central cavity 212. The turbine 30 is rotatably connected to the rotating shaft 15, the first annular cavity 217 is used to avoid the turbine 30, and the second annular cavity 218 is used to contain coolant.

[0036] Furthermore, if Figure 2 and Figure 3 As shown, a water inlet 214 and a water outlet 215 are provided on the base 10, the water inlet 214 is connected to the liquid inlet channel 211, the water outlet 215 is connected to the liquid outlet channel 213, and the water inlet 214 and the water outlet 215 are located on the same side of the base 10. The coolant flows in from the water inlet 214 and flows out from the water outlet 215. By arranging the water inlet 214 and the water outlet 215 on the same side of the base 10, not only can the structure of the base 10 be made more compact, but also it is convenient to connect the water inlet 214 and the water outlet 215 to the external pipeline.

[0037] Optionally, the water inlet 214 and the water outlet 215 are arranged at intervals and do not affect each other, so that the water inlet 214 and the water outlet 215 can be connected to different external pipes respectively. The cavity 21 also includes a thinning groove 216, which is arranged between the water inlet 214 and the water outlet 215. The thinning groove 216 deepens the transition space between the water inlet 214 and the liquid inlet channel 211, and also deepens the transition space between the water outlet 215 and the liquid outlet channel 213, and can save materials and reduce the weight of the base 10.

[0038] Furthermore, if Figure 2 and Figure 3 As shown, the base 10 is provided with a sealing groove 22, which is arranged around the periphery of the liquid inlet channel 211 and the liquid outlet channel 213. The water-cooled radiator 100 includes a sealing ring 70, which is arranged in the sealing groove 22 and elastically clamped between the base 10 and the heat dissipation bottom cover 50 to seal the gap between the base 10 and the heat dissipation bottom cover 50.

[0039] Furthermore, a positioning protrusion 18 is provided on the base 10, and the positioning protrusion 18 is provided at the periphery of the sealing groove 22. The heat dissipation bottom cover 50 abuts against the positioning protrusion 18 to play a positioning role.

[0040] Specifically, if Figure 3 As shown, the positioning protrusion 18 can be annular, and the annular positioning protrusion 18 is protruded around the periphery of the base 10 to form a positioning groove 19. At least part of the heat dissipation bottom cover 50 is accommodated in the positioning groove 19, so as to be positioned by the positioning protrusion 18. On the one hand, it is convenient to align and assemble the heat dissipation bottom cover 50 and the base 10, and on the other hand, it can also prevent the heat dissipation bottom cover 50 from shifting relative to the base 10 to affect the sealing of the water-cooled radiator 100 and avoid the risk of leakage.

[0041] It can be understood that at least two spaced positioning protrusions can be arranged around the periphery of the sealing groove, and positioning holes can be opened on the heat dissipation bottom cover at positions corresponding to the positioning protrusions. The positioning protrusions can be inserted into the positioning holes, so that the heat dissipation bottom cover can be positioned and limited by utilizing the mutual cooperation between the positioning protrusions and the positioning holes, so as to facilitate the alignment and assembly of the heat dissipation bottom cover and the base.

[0042] Furthermore, the base 10 is provided with a plurality of screw holes 23, which surround the periphery of the base 10 and are arranged on the periphery of the sealing groove 22. Screws are passed through the heat dissipation bottom cover 50 and matched with the screw holes 23, so as to fix the heat dissipation bottom cover 50 on the base 10.

[0043] Furthermore, if Figure 4 As shown, Figure 4 yes Figure 3 A schematic diagram of the three-dimensional structure of the base in another perspective. A stud 17 is protruding from the side of the base 10 away from the cavity 21, and a screw hole 23 is formed on the stud 17. By providing the stud 17 on the side of the base 10 away from the cavity 21 and forming the screw hole 23 on the stud 17, on the one hand, the screwing length of the screw and the screw hole 23 can be increased, and the connection strength between the heat dissipation bottom cover 50 and the base 10 can be enhanced. On the other hand, the thickness of the base 10 can be reduced, thereby saving materials and helping to reduce the weight of the base 10.

[0044] See also Figures 1 to 5 , Figure 5 It is a schematic structural diagram of a heat dissipation bottom cover in one embodiment of the present application.

[0045] A plurality of liquid-through grooves 52 are provided on a surface of the heat dissipation bottom cover 50 facing the cavity 21, that is, a plurality of liquid-through grooves 52 are provided on the surface of the heat dissipation bottom cover 50 facing the base 10, and the plurality of liquid-through grooves 52 are arranged in a fan-shaped array, one end of the plurality of liquid-through grooves 52 gathers toward the central area of ​​the heat dissipation bottom cover 50, and the other end of the plurality of liquid-through grooves 52 is radially close to the periphery of the heat dissipation bottom cover 50.

[0046] The heat dissipation bottom cover 50 is arranged in an axisymmetric manner. The heat dissipation bottom cover 50 can be circular, oval, square, racetrack-shaped, etc. A plurality of liquid passages 52 are arranged on one side of the symmetry axis of the heat dissipation bottom cover 50 to play a role in directional liquid pouring.

The side of the heat dissipation bottom cover 50 without the liquid through grooves 52 is correspondingly abutted with the side of the base 10 provided with the liquid outlet 213, so as to separate the liquid inlet 211 and the liquid outlet 213 from each other, so that the coolant must pass through the transition of the central cavity 212 before entering the liquid outlet 213. On the one hand, the coolant can be accelerated by the turbine 30 provided in the central cavity 212, and on the other hand, it can also prevent the coolant from being directly discharged from the liquid outlet 213 after entering the liquid inlet 211, so as to improve the utilization rate of the coolant.

[0048] Furthermore, if Figure 5 As shown, the heat dissipation bottom cover 50 is further provided with a transition groove 54, which is located in the central area of ​​the heat dissipation bottom cover 50 and is connected to the plurality of liquid passage grooves 52. The transition groove 54 is a transition groove opening for machining the liquid passage grooves 52. During the machining of the liquid passage grooves 52, the tool first enters the transition groove 54, and then one by one, machines a plurality of liquid passage grooves 52 that are connected to the transition groove 54. In addition, since the transition groove 54 connects the plurality of liquid passage grooves 52, the flow of the coolant can be made more stable, and the uneven distribution of the coolant in each liquid passage groove 52 can be avoided to affect the running stability of the turbine 30.

[0049] Optionally, the depth of the transition groove 54 can be set greater than the depth of the liquid through groove 52. On the one hand, it can facilitate the entry and exit of the tool, and on the other hand, it can also facilitate the coolant in the liquid through groove 52 to naturally flow into the transition groove 54 under the action of potential energy.

[0050] Alternatively, if Figure 5As shown, the heat dissipation bottom cover 50 can be set to a runway shape, the transition groove 54 can be set to a circle, and the width of the liquid passage 52 can be set to gradually increase in the direction away from the transition groove 54 to gradually reduce the flow resistance of the coolant and increase the circulation volume of the coolant.

[0051] Specifically, the liquid-passing groove 52 includes a first groove surface 521 , a second groove surface 524 and a third groove surface 526 which are connected in sequence. In a direction away from the transition groove 54 , the distance between the first groove surface 521 and the third groove surface 526 gradually increases.

[0052] Optionally, the second groove surface 524 may be configured to be arc-shaped and smoothly connected to the first groove surface 521 and the third groove surface 526 , respectively, so as to reduce the flow resistance of the coolant.

[0053] Furthermore, a plurality of countersunk holes 56 are provided on the surface of the heat dissipation bottom cover 50 away from the liquid passage groove 52. The plurality of countersunk holes 56 are arranged at intervals around the periphery of the heat dissipation bottom cover 50. Fasteners such as screws are arranged in the countersunk holes 56 to connect the heat dissipation bottom cover 50 to the base 10. By providing the countersunk holes 56 for accommodating the fasteners on the surface of the heat dissipation bottom cover 50, the surface of the heat dissipation bottom cover 50 away from the base 10 can be made flat, which is convenient for contact with electronic devices for heat conduction.

[0054] Optionally, the heat dissipation bottom cover 50 may be made of metal or alloy materials such as copper or aluminum to improve heat conduction efficiency.
