Description

Technical Field

[0001] This utility model relates to the field of liquid cooling technology, and in particular to a power supply water cooling plate assembly and a power supply. Background Technology

[0002] Power supplies generate a significant amount of heat during operation. If this heat is not dissipated promptly, the internal temperature of the power supply will rise, affecting its performance and lifespan. High temperatures can lead to degraded performance of electronic components, aging of insulation materials, reduced mechanical strength, and even malfunctions and safety hazards. Therefore, efficient heat dissipation is crucial for the stable operation of a power supply.

[0003] Traditional heat dissipation technologies mainly include air cooling and liquid cooling. With the continuous increase in power supply power and power density, the heat dissipation capacity of air cooling has gradually reached its limit, making it difficult to meet the heat dissipation requirements of high power density power supplies. In addition, air cooling requires a large space to install heat sinks and fans, which is difficult to achieve in compact power supplies. Liquid cooling, on the other hand, has a specific heat capacity and thermal conductivity that are much higher than air, and can absorb and conduct heat more effectively. It can achieve efficient heat dissipation in a smaller space and is suitable for compact power supplies. Therefore, liquid cooling technology is generally used in power supplies to absorb the heat generated in the power supply and conduct it to external heat dissipation devices, and finally dissipate the heat to the external environment of the power supply.

[0004] In existing liquid-cooled power supplies, the inlet and outlet water ports are located on the same side as the power supply's electrical output terminals. This design poses a risk of leakage in practical applications, especially regarding the sealing rings of the inlet / outlet water adapters or the fit of the plug and socket. Specifically, rubber seals may fail to seal properly due to aging, wear, or improper installation, leading to coolant leakage. Furthermore, insufficient fit between the plug and socket can also cause coolant to seep out from the connection point. Leaking liquid from the inlet / outlet water adapters may drip into the power supply, system sockets, or circuit boards, causing electrical problems or contamination.

[0005] To meet the safety requirements of power supply use, the industry urgently needs to develop a power supply water-cooled plate assembly and power supply. Utility Model Content

In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail, in order to highlight the main points of this utility model.

[0047] Server power supplies are high-efficiency, high-reliability power devices specifically designed for servers to provide stable power to components such as the CPU, memory, hard drives, and fans. Server power supply design typically needs to meet requirements such as high power demands, redundancy, hot-swapping capabilities, and efficient heat dissipation to ensure stable server operation.

[0048] Liquid cooling utilizes the high thermal conductivity of liquids to rapidly remove heat, making it suitable for server power supplies. Specifically, server power supplies generate significant heat during operation. Liquid flows into the water channels of a water-cooling plate through the inlet connector, indirectly contacting the heat-generating elements via the plate. After absorbing heat, the liquid flows out through the outlet connector into a cooling tower or condenser to release the heat, effectively lowering the temperature and ensuring stable operation of the server power supply. Server power supplies typically have their inlet, outlet, and electrical output terminals located on the same side. Leakage can occur at the inlet and / or outlet connectors due to issues with rubber seals or the fit of the plug and socket. Leaks can drip into the power supply, sockets, or circuit boards, causing electrical problems or contamination.

[0049] The power supply water-cooled plate assembly of this utility model can solve the problem of electrical or pollution caused by leakage dripping into the power supply, socket or circuit board. It can effectively divert the leakage to the outside of the water-cooled plate assembly, improving the safety of the power supply.

[0050] In one embodiment of this utility model, a power supply water-cooled plate assembly is provided, specifically, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 by, Figure 5 as well as Figure 6 The power supply water-cooled plate assembly includes an inlet connector 23, an outlet connector 24, a first water-cooled plate 20, a water tray 26, and a second water-cooled plate. The first water-cooled plate 20 is fixed to a short side of the second water-cooled plate, forming an L-shaped structure. The short side of the first water-cooled plate 20 is fixedly connected to the short side of the second water-cooled plate, for example, the first water-cooled plate 20 is formed by bending downwards along the length of the second water-cooled plate. The first water-cooled plate 20 and the second water-cooled plate can be integrally formed from a profile. In some embodiments, the short side of the first water-cooled plate 20 and the short side of the second water-cooled plate are welded together using a welding process.

[0051] The first water-cooled plate 20 is provided with an inlet and an outlet, and the inlet and outlet may be provided with internal threads. In some embodiments, the first water-cooled plate 20 may include a base plate and a cover plate fixedly connected together. The base plate of the first water-cooled plate is provided with an inlet and an outlet, and the cover plate of the first water-cooled plate is provided with openings corresponding to the inlet and outlet, so that the inlet connector and the outlet connector can be connected to the inlet and outlet through the corresponding openings.

[0052] The water inlet connector 23 connects to the water inlet on the first water-cooling plate 20, introducing liquid into the first water-cooling plate 20 through the water inlet connector 23. Specifically, the part of the water inlet connector 23 that connects to the water inlet has external threads, which engage with the internal threads of the water inlet to complete the connection between the water inlet connector 23 and the water inlet. A rubber sealing ring is provided between the water inlet connector 23 and the water inlet to prevent liquid leakage at the water inlet connector.

[0053] The water outlet connector 24 connects to the water outlet on the first water-cooling plate 20, and the liquid on the first water-cooling plate is drawn out through the water outlet connector 24. Specifically, the part of the water outlet connector 24 that connects to the water outlet has an external thread, which engages with the internal thread of the water outlet to complete the connection between the water outlet connector 24 and the water outlet. A rubber sealing ring is provided between the water outlet connector 24 and the water outlet to prevent liquid leakage at the water outlet connector.

[0054] It should be noted that the inlet and outlet connectors can be repositioned as needed, and there are no restrictions on their locations. Besides the threaded connection mentioned above, there are other connection methods between the inlet and outlet connectors and the inlet and outlet ports, respectively, which are not limited here.

[0055] In this embodiment, cold liquid is introduced into the first and second water-cooled plates through the water inlet connector, and then the heat-absorbing liquid, such as water, flows out to the external device through the water outlet connector, thereby achieving heat exchange and achieving a good heat dissipation effect.

[0056] The water tray 26 is located below the water inlet connector 23 and the water outlet connector 24 and is fixedly connected to the first water-cooling plate 20, and is used to receive the liquid leaking from the water inlet connector 23 or the water outlet connector 24.

[0057] In this embodiment, the water tray 26 has a base plate and two side walls. The two side walls are located at opposite ends of the upper surface of the base plate, making the cross-section of the water tray 26 U-shaped. The cross-section of the water tray 26 refers to the surface formed after the water tray 26 is cut parallel to the plane of the first water-cooling plate 20. The two side walls of the water tray 26 can prevent leaked liquid from dripping into the power supply or electrical output terminal from both sides of the water tray, effectively holding the liquid. The base plate and two side walls of the water tray 26 can be integrally formed from profiles.

[0058] In this embodiment, the water tray 26 and the first water-cooling plate 20 can be integrally formed from a profile. In some embodiments, the base plate of the water tray 26 and the first water-cooling plate 20 can be integrally formed from a profile. In some embodiments, the inner wall of the bottom plate of the water tray is welded to the outer surface of the first water-cooling plate using a welding process. In other embodiments, the inner wall of the bottom plate of the water tray is welded to the outer surface of the base plate of the first water-cooling plate using a welding process. The water tray 26 is used to receive liquid leaking from the water inlet connector 23 and / or the water outlet connector 24, preventing leaked liquid from dripping into the power supply or electrical output terminal below the water tray, thereby improving the safety of the power supply.

[0059] The second water-cooled plate includes a base plate 21 and a cover plate 22, with the base plate 21 and the cover plate 22 fixedly connected. A first flow channel 27 is formed in the upper surface of the base plate 21. The first end of the first flow channel 27 communicates with the water tray 26, and the second end of the first flow channel 27 communicates with a water nozzle connector 28 provided on the other short side 214 of the second water-cooled plate, for guiding the liquid to the outside of the power supply water-cooled plate assembly. The upper surface of the base plate 21 refers to the surface of the base plate 21 facing the cover plate 22. Specifically, the first flow channel 27 is milled in the upper surface of the base plate 21 by mechanical processes. A groove needs to be cut on the outer surface of the first water-cooled plate to connect the water tray 26 with the first end of the first flow channel 27, allowing the liquid on the water tray 26 to be guided to the first flow channel 27. An opening 281 is provided on the other short side 214 of the second water-cooled plate. The water nozzle connector 28 passes through the opening 281 and is welded to the second end of the first guide groove 27, thereby connecting the water nozzle connector 28 with the second end of the second guide groove 27. Liquid is placed on the water tray 26. The liquid is guided into the second guide groove 27 through the groove on the outer surface of the first water-cooled plate, and then discharged to the outside of the water-cooled plate assembly through the water nozzle connector. By eliminating the liquid leakage at the inlet and outlet connectors, liquid dripping into the power supply or electrical output terminal is prevented, thus improving the safety of power supply use.

[0060] Furthermore, the vertical distance between the first end of the first guide channel 27 and a long side 215 of the second water-cooled plate is greater than the vertical distance between the second end of the first guide channel 27 and the long side 215 of the second water-cooled plate. Specifically, when the long side 215 of the second water-cooled plate is placed vertically with its bottom edge perpendicular to the ground, the first end of the first guide channel 27 is higher than the second end of the first guide channel 27. This height difference helps to drain leaked liquid more quickly and effectively.

[0061] Furthermore, a second guide groove 261 is formed on the first water-cooling plate 20. The second guide groove 261 is located at the intersection of the upper surface of the bottom plate of the water tray 26 and the first water-cooling plate 20, and the second guide groove 261 is connected to the first guide groove 27. Specifically, the second guide groove 261 is formed on the surface of the first water-cooling plate 20 by mechanical process. One inner wall of the second guide groove 261 can be approximately flush with the upper surface of the water tray 26, or one inner wall of the second guide groove 261 can be lower than the upper surface of the water tray 26, so that the liquid received by the water tray 26 can be quickly guided into the second guide groove 261. In this embodiment, the length of the second guide groove 261 can be approximately the same as the length of the inner wall of the bottom plate of the water tray 26, so as to better guide the leaked liquid into the first guide groove 27.

[0062] Furthermore, the angle between the upper surface of the bottom plate of the water tray 26 and the first water-cooling plate 20 is less than 90°, allowing the liquid to flow directly into the inner wall of the water tray and preventing liquid from flowing out from the outer wall of the water tray 26, thus avoiding electrical and contamination problems. The outer wall of the water tray 26 is the side wall of the end of the water tray 26 furthest from the first water-cooling plate 20. In this embodiment, the upper surface of the bottom plate of the water tray 26 forms a certain angle with the horizontal plane; that is, the distance between the outer side of the upper surface of the bottom plate of the water tray 26 and the horizontal plane is greater than the distance between the inner side of the upper surface of the bottom plate of the water tray 26 and the horizontal plane. The outer side of the upper surface of the bottom plate of the water tray 26 is the side furthest from the first water-cooling plate 20, and the inner side of the upper surface of the bottom plate of the water tray 26 is the side connected to the first water-cooling plate 20. In this embodiment, the bottom plate of the water tray 26 has a uniform thickness, and the entire bottom plate of the water tray 26 forms a certain angle with the horizontal plane. In some embodiments, the thickness of the water tray 26 is uneven, with the side closer to the first water-cooling plate 20 being thinner than the side farther from the first water-cooling plate 20, and the lower surface of the bottom plate of the water tray 26 being parallel to the horizontal plane.

[0063] Furthermore, water channels are formed within the upper surface of the substrate 21, namely an inlet water channel 251 and an outlet water channel 252. The first end of the inlet water channel 251 (e.g., the first end of the channel) is connected to the water inlet on the first water-cooled plate 20, and the first end of the outlet water channel 252 (e.g., the second end of the channel) is connected to the water outlet on the first water-cooled plate 20. The tail ends of the inlet water channel 251 and the tail ends of the outlet water channel 252 are connected to form a U-shaped water channel, and the inlet water channel 251 and the outlet water channel 252 are separated by a partition. The inlet water channel 251 and the outlet water channel 252 are located between the first guide groove 27 and the other long side of the second water-cooled plate. When the second water-cooled plate is placed vertically with one long side 215 as the bottom edge, the inlet water channel 251 and the outlet water channel 252 are located above the first guide groove 27.

[0064] In this embodiment, the first water-cooled plate 20 needs to have an inlet groove and an outlet groove inside. The inlet groove connects the inlet channel to the inlet, and the outlet groove connects the outlet channel to the outlet.

[0065] Furthermore, the power supply water-cooled plate assembly also includes an upper cover plate 29, which is fixedly connected to one long side of the first water-cooled plate 20 and the other long side of the second water-cooled plate. In this embodiment, the upper cover plate 29, the first water-cooled plate 20, the water tray 26, and the base plate 21 of the water-cooled plate can be integrally formed from a profile. In some embodiments, the upper cover plate 29, the first water-cooled plate 20, and the base plate 21 of the water-cooled plate can be integrally formed from a profile. In other embodiments, the upper cover plate 29 is fixedly connected to one long side of the first water-cooled plate 20 and the other long side of the second water-cooled plate by welding or fasteners.

[0066] Furthermore, the second water-cooled plate has first grooves 211 and 212 on its long side 215 for accommodating the protrusion in the power supply lower housing assembly.

[0067] Furthermore, a second groove 213 is formed in the upper surface of the substrate 21, which is used to accommodate the cover plate 22. Specifically, the cover plate 22 is first placed in the second groove 213, and then the cover plate 22 is welded to the substrate 21 by a continuous welding process.

[0068] This application also provides a power supply, as detailed in the following reference. Figure 6 , Figure 7 , Figure 8 as well as Figure 9 The power supply includes a lower housing assembly 3; a power module 1 disposed on the base plate 3 of the lower housing assembly; and a power water-cooling plate assembly 2 as described above. The power water-cooling plate assembly is fixedly assembled to the lower housing assembly by fasteners. The structure of the power water-cooling plate assembly 2 has been described above and will not be repeated here.

[0069] The power supply lower housing assembly 3 includes a lower cover plate and adjacent long side plates and short side plates, which can be integrally formed from profiles. In some embodiments, the long side plates and short side plates can be mechanically fixedly connected to two adjacent sides of the lower cover plate, respectively.

[0070] Specifically, a power socket is provided on one short side of the power module 1, and an electrical output terminal is provided on the other short side of the power module 1. The power module 1 is placed on the lower cover plate, and the power water-cooling plate assembly is fixedly assembled with the power lower housing assembly using fasteners such as screws and bolts. That is, the long side 215 of the second water-cooling plate is fixedly connected to the long side of the lower cover plate using screws and other fasteners, and the upper cover plate is fixedly connected to the long side of the power lower housing assembly using fasteners. The long side is arranged opposite to the second water-cooling plate, while the short side plate is arranged opposite to the first water-cooling plate. A U-shaped groove is formed on the short side plate to accommodate the power socket on the power supply.

[0071] Furthermore, the width of the first water-cooled plate 21 is smaller than the width of the second water-cooled plate, so that the electrical output terminal of the power supply can extend out of the housing from the space between the first water-cooled plate and the lower cover plate, facilitating connection with external equipment.

[0072] Furthermore, two protrusions are provided on the long side of the lower cover plate, with the long side facing the long side plate. These two protrusions are accommodated in two first grooves 211 and 212 on the long side 215 of the second water-cooling plate, so that the power supply water-cooling plate assembly and the power supply lower housing assembly can be better assembled together.

[0073] In this embodiment, the leaking liquid from the inlet and outlet water connectors is diverted to the outside of the power supply water cooling plate assembly through the water tray, the first guide channel, and the water nozzle connector. This prevents the liquid from dripping into the power supply or the system socket and circuit board, which could cause electrical or pollution problems, and improves the safety of power supply use.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
