[0019] The present invention will now be described in detail with reference to the accompanying drawings.

[0020] like Figures 1 to 2 As shown, this utility model discloses a water-cooled module with high heat conduction efficiency, including a water-cooled plate 1, a water inlet 2, and a water outlet 3.

[0021] The water-cooled plate 1 has a heat exchange chamber 11 inside, which is provided with a first flow branching zone 12, a second flow branching zone 13, and a confluence zone 14. The heat exchange chamber 11 provides internal space for the flow of coolant and heat exchange. This allows the coolant to circulate inside the water-cooled plate 1 and achieve heat conduction with the water-cooled plate 1.

[0022] The inflow zone 14 is used to collect the coolant from the first diversion zone 12 and the second diversion zone 13; the flow of coolant is planned through the first diversion zone 12 and the second diversion zone 13. The coolant is diverted into the first diversion zone 12 and the second diversion zone 13 to increase the contact area between the coolant and the water-cooled plate 1, improve the heat exchange efficiency, and then collect in the inflow zone 14.

[0023] The coolant collection zone provides a centralized area for the diverted coolant to re-converge. This facilitates the unified discharge of coolant and ensures the integrity of the coolant circulation.

[0024] The inlet 2 is connected to the first diversion zone 12 and the second diversion zone 13 respectively, and is used to supply coolant to the first diversion zone 12 and the second diversion zone 13. The coolant is supplied to the first diversion zone 12 and the second diversion zone 13 through the inlet 2 to ensure that the coolant can enter the two diversion zones in a timely manner and ensure the continuous heat exchange.

[0025] The outlet 3 is connected to the inlet area 14 and is used to drain the coolant. The coolant that has completed heat exchange is drained through the outlet 3, and the coolant that has absorbed heat is discharged in a timely manner to maintain the continuous and efficient heat conduction capability of the water-cooled module.

[0026] When the water-cooled module is working, coolant flows into the heat exchange chamber 11 of the water-cooled plate 1 through the inlet 2. The coolant is precisely guided and quickly distributed to the first distribution zone 12 and the second distribution zone 13. In these two zones, the coolant comes into full contact with the water-cooled plate 1, efficiently exchanging heat and absorbing heat. Afterward, the coolant flows into the collection zone 14. The collection zone 14 provides a space for the coolant to converge, and after the coolant has gathered in the collection zone 14, it is discharged from the outlet 3 located in the collection zone 14. In this way, the coolant continuously circulates, continuously carrying heat out of the water-cooled plate 1, ensuring complete coolant circulation and continuous heat conduction within the water-cooled plate 1, effectively improving the heat transfer efficiency of the water-cooled module.

[0027] like Figure 1 As shown, the heat exchange cavity 11 in this embodiment is provided with a partition bar 4 and a flow divider 5; The partition bar 4 is longitudinally arranged within the water-cooled plate 1. The first diversion zone 12 is located on one side of the partition bar 4, and the second diversion zone 13 is located on the other side of the partition bar 4. This longitudinal arrangement creates a physical separation structure within the water-cooled plate 1. This divides the heat exchange chamber 11 into two relatively independent parts, providing a basis for the formation of the first diversion zone 12 and the second diversion zone 13. This facilitates the diversion and flow of coolant, increases the contact area between the coolant and the water-cooled plate 1, and improves heat exchange efficiency. Simultaneously, it allows the coolant to flow separately in the first diversion zone 12 and the second diversion zone 13, increasing the flow path of the coolant within the heat exchange chamber 11 and the contact time with the water-cooled plate 1, further enhancing the heat exchange effect.

[0028] The diverter block 5 is horizontally positioned on one side of the partition bar 4, and the confluence area 14 is located at the end of the diverter block 5 opposite to the partition bar 4. The horizontal arrangement of the diverter block 5 guides and collects the coolant, assisting in the flow of coolant within the heat exchange chamber 11 and ensuring smoother flow. The confluence area 14 provides a concentrated space for the diverted coolant to collect, facilitating the unified discharge of coolant that has completed heat exchange, ensuring the integrity of coolant circulation, and maintaining the continuity of heat conduction.

[0029] like Figure 1 As shown, the first diversion zone 12 of this embodiment is provided with a first flow channel 121 for conveying coolant; the first flow channel 121 provides a dedicated flow channel for coolant in the first diversion zone 12, so that coolant can flow in an orderly manner in the first diversion zone 12, and it is convenient to control the flow direction and flow rate of coolant.

[0030] The second diversion zone 13 is provided with a second flow channel 131 for conveying coolant; the second flow channel 131 constructs a specific flow path for the coolant in the second diversion zone 13, ensuring stable flow of coolant in the second diversion zone 13 and facilitating heat exchange.

[0031] The first flow channel 121, the second flow channel 131, and the inlet area 14 are all connected. A complete coolant circulation path is constructed, allowing the coolant in the first branch area 12 and the second branch area 13 to smoothly flow into the inlet area 14, realizing smooth circulation of coolant within the water-cooled module and improving heat transfer efficiency.

[0032] like Figure 2 As shown, in this embodiment, the heat exchange cavity 11 penetrates the water-cooled plate 1, and the water-cooled plate 1 is provided with a front plug 6 and a rear plug 7. By the heat exchange cavity 11 penetrating the water-cooled plate 1, a continuous and through flow space is provided for the coolant inside the water-cooled plate 1, allowing the coolant to flow fully in the length direction of the water-cooled plate 1, thereby increasing the contact range with the water-cooled plate 1 and improving the possibility of heat exchange.

[0033] The front plug 6 is located at one end of the water-cooled plate 1 and is used to seal one end of the heat exchange chamber 11; the front plug 6 seals one end of the heat exchange chamber 11 to prevent coolant from leaking from that end; The rear plug 7 is located at the other end of the water-cooled plate 1 and is used to seal the other end of the heat exchange cavity 11. By sealing the other end of the heat exchange cavity 11 with the rear plug 7, the coolant is prevented from flowing out from the other end, thereby ensuring that the coolant can flow in the heat exchange cavity 11 along a predetermined path and improving the heat transfer efficiency.

[0034] like Figure 2 As shown, in this embodiment, a first sealing groove 15 is provided at one end of the water-cooled plate 1, and a front plug 6 is disposed in the first sealing groove 15. By embedding the front plug 6 into the first sealing groove 15, a sealing structure is formed by the tight fit between the front plug 6 and the first sealing groove 15. This effectively prevents coolant leakage from the connection between the water-cooled plate 1 and the front plug 6, ensuring that the coolant flows along a predetermined path within the heat exchange chamber 11, thereby improving the heat transfer efficiency of the water-cooled module.

[0035] like Figure 2 As shown, in this embodiment, a second sealing groove 16 is provided at the other end of the water-cooled plate 1, and the rear plug 7 is disposed in the second sealing groove 16. The tight fit between the rear plug 7 and the second sealing groove 16 forms a reliable sealing structure. This effectively prevents coolant leakage from the connection between the water-cooled plate 1 and the rear plug 7, ensuring that the coolant circulates within the heat exchange chamber 11 along a predetermined path, thereby improving the heat transfer efficiency of the water-cooled module.

[0036] In this embodiment, the flow divider 5 is connected to the inner wall of the heat exchange chamber 11 on both its upper and lower surfaces via friction stir welding. The high-speed rotating stirring head generates heat through friction with the workpiece during friction stir welding, bringing the material in the contact area to a thermoplastic state and achieving a strong metallurgical bond. This connection method ensures a tight and stable connection between the flow divider 5 and the inner wall of the heat exchange chamber 11, effectively preventing coolant leakage from the connection point during flow and ensuring that the coolant flows within the heat exchange chamber 11 along a predetermined path. This improves the heat transfer efficiency of the water-cooled module and enhances the overall stability and reliability of the water-cooled module structure.

[0037] like Figure 1 As shown, in this embodiment, both the inlet 2 and the outlet 3 include a connecting end 31 and a sleeve end 32. Connection end 31 is connected to water-cooled plate 1; Socket 32 ​​is used for connection to external devices.

[0038] The inlet 2 and outlet 3 are securely fixed to the water-cooled plate 1 by means of threaded connection or welding, so as to achieve communication with the heat exchange chamber 11 inside the water-cooled plate 1. This ensures that the coolant can smoothly enter the heat exchange chamber 11 of the water-cooled plate 1 from the outside (inlet 2) and exit from the heat exchange chamber 11 to the outside (outlet 3), thus ensuring the stability of the coolant circulation.

[0039] like Figure 1 As shown, the socket end 32 in this embodiment is provided with multiple anti-slip grooves 33. The anti-slip grooves 33 increase the surface roughness of the socket end 32, increasing the friction between the socket end 32 and the connection point (such as a pipe) when connected to external equipment. During the connection process, this effectively prevents the socket end 32 from loosening or slipping due to vibration, external forces, or other factors, ensuring the stability and sealing of the connection. This, in turn, ensures that coolant does not leak when entering or exiting the water-cooling plate 1, maintaining the stable and efficient operation of the water-cooling module and improving the reliability of heat transfer.

[0040] like Figure 1 As shown, protective strips 17 are provided on both sides of the water-cooled plate 1 in this embodiment. By adding a protective structure with a certain strength and toughness to the side of the water-cooled plate 1, the protective strips 17 form a physical wrap and support for the side of the water-cooled plate 1. When the water-cooled plate 1 is subjected to external forces such as collisions and scratches during installation, transportation or use, the protective strips 17 can first bear and disperse these external forces, avoiding direct damage to the side of the water-cooled plate 1, thereby protecting the internal structure of the water-cooled plate 1 from damage, maintaining the normal heat conduction function of the water-cooled plate 1, and extending the service life of the water-cooled plate 1.

[0041] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
