[0072] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0073] As shown in Figure 1, Embodiment 1 of the present invention provides a water-cooled heat dissipation device, comprising:

[0074] The radiator module 1 includes multiple branch pipes, a water inlet pipe 11, and a branch chamber 32, wherein the branch chamber 32 is connected to the multiple branch pipes and the water inlet pipe 11.

[0075] The water inlet and outlet module 3 includes an inlet chamber 311 and an outlet chamber. The plurality of diverter pipes are connected to the outlet chamber, and the inlet chamber 311 is connected to the outlet chamber.

[0076] Pump module 4 includes multiple impeller chambers and a manifold, wherein the multiple impeller chambers are connected and communicate with the outlet chamber of the inlet and outlet water module 3;

[0077] The cold liquid passes sequentially through the inlet chamber 311, the inlet pipe 11, the diversion chamber 32, the multiple diversion pipes, the outlet chamber, and the multiple impeller chambers before flowing into the confluence channel.

[0078] In this embodiment of the invention, the radiator module 1 consists of heat sinks and a fan, used to dissipate the heat absorbed by the coolant into the surrounding environment. The fan blows heat across the heat sinks, accelerating heat transfer and dissipation, thereby reducing the temperature of the coolant. The inlet / outlet water module 3 is an interface device connecting the radiator module 1 and the pump module 4, responsible for guiding the coolant into the radiator module 1 for heat dissipation and discharging the coolant after it has been cooled by the radiator module 1. The pump module 4 is used to circulate the coolant. The pump module 4 has two pump sets to provide power for the flow of the coolant, ensuring that the coolant can continuously circulate and dissipate heat. The inlet / outlet water module 3 and the pump module 4 form a dual-pump parallel module pump-discharge integrated structure, increasing the system flow rate and thus improving the heat dissipation performance. It also improves the overall system power, reduces the working pressure of the pump module, and thus increases its service life. The connection between the pump module and the inlet / outlet water module 3 and the radiator module 1 reduces the size of the cold head and makes the overall design aesthetically pleasing and integrated.

[0079] Preferably, the pump module 4 is integrally formed with the inlet / outlet water module 3.

[0080] As shown in Figures 1 to 9, the pump module 4 further includes multiple water-guiding impellers, which are correspondingly housed in multiple impeller cavities. The multiple water-guiding impellers drive the fluid in the outlet chamber to the multiple impeller cavities and then discharge it after converging through the confluence channel.

[0081] The multiple impeller cavities are configured in parallel;

[0082] The multiple water-drawing impellers may rotate in the same or different directions;

[0083] The plurality of impeller chambers include: a first impeller chamber 421 and a second impeller chamber 422, and a first water-drawing impeller 47 and a second water-drawing impeller 48 respectively housed in the first impeller chamber 421 and the second impeller chamber 422.

[0084] The first impeller cavity 421 and the second impeller cavity 422 are connected to the water outlet chamber;

[0085] The water outlet chamber is connected to the plurality of diversion pipes;

[0086] The pump module 4 includes a first impeller 47 that rotates clockwise and a second impeller 48 that rotates counterclockwise.

[0087] In this embodiment of the invention, multiple water-guiding impellers are placed in multiple impeller chambers to drive the fluid from the outlet chamber into the corresponding impeller chamber, and then discharge it after converging through the confluence channel. The kinetic energy generated by the rotation of the water-guiding impellers can cause the coolant to form a vortex in the impeller chamber, increasing the cooling effect. The multiple water-guiding impellers can rotate in the same direction or in different directions. By adjusting the rotation direction of the water-guiding impellers, the cooling effect can be further optimized, making the coolant form a more complex flow state in the impeller chamber, thereby improving the heat dissipation efficiency. The impeller chamber includes a first impeller chamber 421 and a second impeller chamber 422, and also includes a corresponding matching first impeller chamber 421. The first water-priming impeller 47 and the second water-priming impeller 48 ensure a stable flow of coolant within the impeller cavity and fully utilize the kinetic energy of the water-priming impellers to improve the cooling effect. Multiple branch pipes, including the inlet pipe 11 and the second pipe 13, are connected to the outlet chamber. Simultaneously, the outlet chamber is also connected to the first impeller cavity 421 and the second impeller cavity 422, ensuring smooth flow of coolant and effectively removing heat from the heat source. The first water-priming impeller 47 in the pump module 4 rotates clockwise, while the second water-priming impeller 48 rotates counterclockwise, increasing the flow path of coolant within the pump module and improving the cooling effect.

[0088] Referring to Figure 8, in Example 1, the first water-inlet impeller 47 rotates clockwise, and the second water-inlet impeller 48 rotates counterclockwise.

[0089] Preferably, the first water intake impeller 47 rotates clockwise and the second water intake impeller 48 rotates counterclockwise, driving the fluid direction upward. This helps to reduce the collision caused by the large difference in direction between the two fluids, as well as the flow resistance caused by the collision between the fluids and the guide plate 425. At the same time, the impeller structures of the first water intake impeller 47 and the second water intake impeller 48 are designed differently to ensure that both can draw coolant from the radiator side to the pump chamber using the centrifugal force of the pump.

[0090] As shown in Figures 1 to 9, the water outlet chamber includes a first water outlet chamber 313 and a second water outlet chamber 312;

[0091] The plurality of diversion pipes include a second pipe 13 and a third pipe 12;

[0092] The first water outlet chamber 313, the second pipe 13, and the first impeller chamber 421 are connected in sequence to form a liquid flow branch;

[0093] The second outlet chamber 312, the third row of pipes 12, and the second impeller chamber 422 are connected in sequence to form another liquid flow branch;

[0094] Two liquid flow branches converge at one point on one side of multiple impeller chambers via a confluence channel and are then discharged. On the other side, the liquid flow flows into the diversion chamber 32 through the inlet pipe and is diverted to the second pipe 13 and the third pipe 12. Driven by the first water inlet impeller 47 and the second water inlet impeller 48, the liquid flow through the diversion chamber 32 and the confluence channel is connected to form a parallel liquid flow circulation channel.

[0095] Similarly, multiple impeller cavities, namely: the first impeller cavity 421, the second impeller cavity 422, ... the (N-1)th impeller cavity, the Nth impeller cavity, are configured in parallel.

[0096] And the corresponding multiple water inlet pipes, namely, the second pipe 13, the third pipe 12, ... the (N-1)th pipe, the Nth pipe,

[0097] In the case of the first water outlet chamber 313, the second water outlet chamber 312, ... the N-1th water outlet chamber and the Nth water outlet chamber, parallel liquid flow circulation can also be achieved.

[0100] The inlet / outlet module 3 further includes a manifold chamber 314, the input end of which is connected to the manifold channel of the pump module 4, and is not connected to the outlet chamber and the inlet chamber 311 within the inlet / outlet module 3.

The output ends of the first water outlet chamber 313 and the second water outlet chamber 312 are connected to the input ends of the first impeller chamber 421 and the second impeller chamber 422, respectively. The input ends are matched and connected to the output ends of the second row of pipes 13 and the third row of pipes 12, respectively. The coolant enters the first water outlet chamber 313 and the second water outlet chamber 312 from the output ends of the second row of pipes 13 and the third row of pipes 12, respectively, and then enters the first impeller chamber 421 and the second impeller chamber 422 to achieve a cooling effect. The water inlet and outlet module 3 also includes a manifold chamber 314. The input end of the manifold chamber 314 is connected to the manifold channel of the pump module 4. At the same time, the manifold chamber 314 is not connected to the water outlet chamber and the water inlet chamber, so that the coolant from the pump module 4 can be concentrated and introduced into the manifold chamber 314 through the manifold channel.

[0102] As shown in Figures 1 to 9, the water-cooled heat dissipation device also includes a water inlet nozzle 33 and a water outlet nozzle 34.

[0107] As shown in Figures 1 to 9, the plurality of diversion pipes are parallel to the inlet pipe 11 and pass through the first cover plate 35. The first cover plate 35 abuts against and covers one side of the inlet / outlet module 3.

The pump module 4 realizes the circulation of coolant, achieving a heat dissipation effect.

[0115] As shown in Figures 1 to 9, the output end of the water outlet chamber is provided with a first water inlet 315 and a second water inlet 316.

The coolant that has been cooled in the first outlet chamber 313 enters the pump module 4 through the first water inlet 411; the coolant that has been cooled in the second outlet chamber 312 enters the pump module 4 through the second water inlet 412; then the pump module 4 discharges the cooled coolant.
