[0002] A water-cooled radiator mainly consists of a radiator, water pipes, a water pump, and a sufficient water source. The water pump delivers water to the radiator through the water pipes, where the water exchanges heat with the radiator. The water pump drives the water source to circulate, and the water carrying heat flows out, while new, cool water continues to absorb heat to cool the radiator.

[0003] Currently, the water flow rate of water-cooled radiators on the market is relatively slow, which prevents the water carrying heat from flowing out in time and prevents new low-temperature water from entering the radiator in time, resulting in low heat dissipation efficiency of water-cooled radiators. Utility Model Content

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Figure 1 This is a schematic diagram of the water pump structure of the water-cooled radiator in this utility model. Figure 2 This is an exploded view of the water pump in this utility model. Figure 3 This is a cross-sectional view of the water pump of this utility model. The water pump includes: a water pump housing 1 and a lower cover 2; the water pump housing 1 has a first receiving cavity 11 and a second receiving cavity 12, a first centrifugal pump 13 is disposed in the first receiving cavity 11, and a second centrifugal pump 14 is disposed in the second receiving cavity 12; the lower cover 2 is recessed on the side near the water pump housing 1 to form a flow channel 21, and a water outlet 22 is disposed on the lower cover 2; when the water pump housing 1 and the lower cover 2 are closed, the flow channel 21 connects the first receiving cavity 11 and the second receiving cavity 12, and the output end of the second centrifugal pump 14 faces the water outlet 22. In this embodiment, the flow channel 21 is used to connect the first receiving cavity 11 and the second receiving cavity 12. The first centrifugal pump 13 is used to pressurize the water flow in the first receiving cavity 11 and increase the flow rate of the water flow. The second centrifugal pump 14 is used to pressurize the water in the second receiving cavity 12 and spray it to the outside, so that the water flow has enough kinetic energy to enter the radiator, increase the flow rate of the water flow, and remove the heat in the radiator more quickly, thereby improving the heat dissipation effect of the water-cooled radiator.

[0029] Furthermore, a limiting boss 15 is provided between the first receiving cavity 11 and the second receiving cavity 12. The limiting boss 15 is recessed inward near the side wall of the second receiving cavity 12 to form an arc-shaped drainage portion. The limiting boss 15 is used to restrict the water flow in the first receiving cavity 11 from flowing into the second receiving cavity 12 from different directions, so that the water flow in the first receiving cavity 11 can only flow into the second receiving cavity 12 through the flow channel 21. This ensures that during use, the water flow from the first receiving cavity 11 directly flows into the second receiving cavity 12 through the flow channel 21. The drainage portion is used to guide the water flow located in the flow channel 21 into the second receiving cavity 12 and to the input end of the second centrifugal pump 14. This ensures that the resistance of the water flow is minimized when it flows in the pump, avoids energy loss during the flow, and ensures that the water flow has sufficient output pressure to enter the second centrifugal pump 14, which is beneficial for the second centrifugal pump 14 to have sufficient pressure output water flow.

[0030] Furthermore, the pump housing 1 is provided with a water inlet 16, which communicates with the first receiving cavity 11. The water inlet 16 and the first receiving cavity 11 are connected by a water inlet channel, and the end of the water inlet channel near the first receiving cavity 11 has a flow-guiding protrusion 161. The flow-guiding protrusion 161 is used to guide the water flow entering through the water inlet 16 to the input end of the first centrifugal pump 13 in the first receiving cavity 11, which can ensure that the resistance of the water flow is minimized when the water flows in the pump, which helps to reduce the energy loss of the water flow and improve the efficiency of the water flow; and the flow-guiding protrusion 161 ensures that the water flow follows a predetermined path, avoiding the generation of eddies and turbulence at the water inlet channel, which helps to maintain the stability and continuity of the water flow, thereby improving the overall efficiency of the pump.

[0031] Furthermore, the first centrifugal pump 13 and the second centrifugal pump 14 are connected in series within the pump housing 1. The series connection of the first centrifugal pump 13 and the second centrifugal pump 14 increases the pump's head. After the first centrifugal pump 13 ejects water at a certain pressure, the water flows into the second centrifugal pump 14, which further pressurizes the water flow. This allows the first centrifugal pump 13 and the second centrifugal pump 14 to provide a higher head, ensuring that the liquid can be smoothly delivered to the target location.

[0032] Furthermore, a baffle 17 is provided inside the first receiving cavity 11, and the baffle 17 is located at the connection between the first receiving cavity 11 and the flow channel 21. The baffle 17 is used to block the water flow in the first receiving cavity 11, preventing the water flow from directly entering the flow channel 21. This facilitates guiding the water flow into the first centrifugal pump 13 for pressurization, giving the water flow higher kinetic energy to flow into the flow channel. This helps guide the fluid flow within the receiving cavity, ensuring that the fluid can enter the flow channel 21 along a predetermined path and then enter the second receiving cavity 12 along the flow channel 21.

[0033] Furthermore, the baffle 17 has a flow hole 171 located below the output end of the first centrifugal pump 13. The flow hole 171 connects the first receiving cavity 11 and the flow channel 21, allowing water in the first receiving cavity 11 to enter the flow channel 21 through the flow hole 171. The flow hole 171 restricts the water flow rate, achieving precise control of flow rate and pressure. Moreover, the flow hole 171 promotes uniform fluid distribution and flow, helping to reduce turbulence and eddies near the baffle 17 and improving the overall efficiency of the system.

[0034] Furthermore, a fixing part 18 is provided on the water pump housing 1, which surrounds the first centrifugal pump 13 and the second centrifugal pump 14; the fixing part 18 has a limiting plate located in the middle area of ​​the fixing part 18. The fixing part 18 is used to limit the position of the first centrifugal pump 13 and the second centrifugal pump 14, preventing the first centrifugal pump 13 and the second centrifugal pump 14 from shaking and shifting their positions during use, which could cause the output ends of the first centrifugal pump 13 and the second centrifugal pump 14 to shift and collide with the water pump housing 1, resulting in damage. This helps to fix the working position of the first centrifugal pump 13 and the second centrifugal pump 14, reduces the risk of shaking of the first centrifugal pump 13 and the second centrifugal pump 14, and extends the service life of the first centrifugal pump 13 and the second centrifugal pump 14.

[0035] Furthermore, the first centrifugal pump 13 includes a first rotor 131, a first rotating shaft 132, and a first impeller 133. The first rotor 131 is connected to the first rotating shaft 132, and the first rotating shaft 132 is connected to the first impeller 133. A first winding group is arranged around the first rotor 131. The first rotor 131 is driven to rotate by the magnetic field generated by the first winding group, which drives the first rotating shaft 132 to rotate, and in turn drives the first impeller 133 to rotate. When the first winding assembly is energized, it generates a magnetic field. The first rotor 131, influenced by this magnetic field, begins to rotate, driving the first shaft 132 to rotate. The rotation of the first shaft 132 then drives the first impeller 133 to rotate. The rotation of the first impeller 133 creates a low-pressure zone at its center. Under the influence of atmospheric pressure or liquid surface pressure difference, water is continuously drawn into the center of the impeller. The water, under the high-speed rotation of the impeller, is subjected to centrifugal force and thrown from the center to the outer edge of the impeller, gaining kinetic and static pressure energy, thereby increasing the water pressure. This increases the pressure of the water flowing towards the second centrifugal pump 14. Similarly, the structure of the second centrifugal pump 14 is the same as that of the first centrifugal pump 13, and their working principle is the same. After the second centrifugal pump 14 draws in water, it rotates its impeller, causing the water to be sprayed from the outlet 22 into the water-cooled radiator, increasing the water flow velocity and carrying away heat from the radiator more quickly, thus improving the heat dissipation effect of the water-cooled radiator.

[0036] Furthermore, the outlet 22 is a Y-shaped outlet 22. The Y-shaped outlet 22 design helps reduce fluid resistance during outflow, allowing the fluid to flow out more smoothly and increasing flow rate and velocity. The Y-shaped bifurcated structure ensures that the fluid is evenly distributed in two or more directions during outflow, contributing to a more uniform heat dissipation effect.

[0037] Furthermore, a sealing strip 19 is provided on the side of the water pump housing 1 near the lower cover 2, and the sealing strip 19 is located around the first receiving cavity 11 and the second receiving cavity 12. When the water pump housing 1 and the lower cover 2 are closed, the sealing strip 19 is subjected to the pressure of the water pump housing 1 and the lower cover 2, causing the sealing strip 19 to deform and adhere to the water pump housing 1 and the lower cover 2. The sealing strip 19 is used to seal the first receiving cavity 11 and the second receiving cavity 12, preventing moisture in the first receiving cavity 11 and the second receiving cavity 12 from flowing out from the gap between the water pump housing 1 and the lower cover 2 during use, which would affect the pressurization and liquid delivery capacity of the water pump of the water-cooled radiator, and help maintain the working stability of the water pump.

[0038] In summary, this utility model improves the heat dissipation effect of a water-cooled radiator by installing a first centrifugal pump and a second centrifugal pump inside the water pump housing. The first centrifugal pump pressurizes the water flow, and the second centrifugal pump draws in the water flow and sprays it into the water-cooled radiator. This increases the flow rate of the water, removes heat from the radiator more quickly, and improves the heat dissipation effect of the water-cooled radiator.

[0039] Furthermore, the water pump of the water-cooled radiator provided in the embodiments of this utility model has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
