Description

Technical Field

[0001] This utility model relates to the field of power supply protection technology, and in particular to a water-cooling device and a composite protective enclosure. Background Technology

[0002] In power supply equipment, the power supply housing is a crucial component, and its performance directly affects the overall operating status and lifespan of the power supply. Currently, existing power supply housings typically need to meet multiple functional requirements.

[0003] First, in terms of protection, the power supply casing must be able to withstand external dust, moisture, vibration and impact, etc., to prevent these factors from damaging internal circuit boards and other components, and to ensure the normal operation of the power supply.

[0004] Second, shielding is also an important feature of the power supply housing. Since the internal circuit of the power supply generates electromagnetic signals when it is working, and external electromagnetic signals may also interfere with the internal circuit of the power supply, the power supply housing needs to have good shielding performance to isolate internal and external electromagnetic interference and ensure the stable operation of the power supply.

[0005] Third, as the power of the power supply continues to increase, the heat generated during its operation also increases significantly. Timely heat dissipation is crucial for the normal operation of the power supply.

[0006] However, in existing power supply housings, since the input and output ports are usually located on the same side, the power transmission path from the input terminal to the output terminal after the live and neutral wires are connected to the circuit board forms a U-shape. This longer path not only increases energy loss and reduces power supply efficiency, but also makes the power lines more susceptible to external electromagnetic interference due to the high-frequency signals in the secondary circuits on the input and output port sides. This increases circuit instability and affects the power supply's output performance and lifespan.

[0007] Therefore, optimizing the incoming line path and reducing line loss and instability while ensuring that the power supply casing has protection, shielding and heat dissipation functions has become an urgent technical problem to be solved. Utility Model Content

[0008] This utility model provides a water-cooling device and a composite protective enclosure, which solves the technical problems of existing power supply devices having poor anti-interference performance in harsh working environments, resulting in low stability and low working efficiency.

[0009] To solve the above technical problems, this utility model provides a water cooling device, comprising: A water-cooled plate with a cavity inside forming a water-cooled tank, the water-cooled tank being filled with coolant; The power connector has its main body recessed and embedded in the water-cooled plate, spatially isolated from the circuit components. One end is connected to an external device, and the other end is electrically connected to the power supply terminal of the circuit components. The water-cooled plate is located close to the side of the circuit assembly and in close contact with the power connector for heat exchange and heat dissipation. It also uses its own housing to separate the power connector from the circuit assembly and shield the electromagnetic interference generated by the power connector.

[0010] This basic design incorporates a water-cooled plate positioned close to the side of the circuit components. Replacing the power supply housing side plate with this water-cooled plate provides waterproofing and dustproofing while simultaneously offering liquid cooling, thus facilitating the miniaturization of the device and effectively improving its operating efficiency. Furthermore, the water-cooled plate is improved by recessing and embedding the power connectors within it. This not only simultaneously cools the power connectors but also isolates them from the circuit components through the housing, shielding them from electromagnetic interference generated by the power connectors. This provides a stable operating environment, improves circuit stability, and ultimately ensures the normal operation of the power supply unit.

[0011] In a further embodiment, the top and / or bottom of the water-cooled plate are provided with a wire groove, the wire groove is recessed inward to form a sunken strip groove, the strip groove extends radially and is parallel to the flow direction of the water-cooled groove, and both ends open inward to connect to the power connector; The depth of the groove is greater than the diameter of the power connector.

[0012] This design incorporates a recessed, strip-shaped groove to fully isolate the power connector from the circuit components, blocking the direct path of noise radiation and crosstalk. The depth of the groove is greater than the diameter of the power connector, completely concealing the power connector within the water-cooling plate while preventing liquid and foreign object intrusion, effectively protecting the power connector and circuit components from corrosion.

[0013] In a further embodiment, a fixing platform is constructed by protruding inward from the inner side of the cable tray. Several fixing holes are evenly distributed on the top surface of the fixing platform, and the height of the platform is flush with the water-cooled plate. The water-cooled plate is mounted on the power supply housing as a side plate through the fixing holes. The fixing platform, the power supply housing, and the inner wall of the water-cooled plate form a shielding cavity, which isolates the shielding cavity from the central area of ​​the cable tray, thereby performing electromagnetic isolation between the circuit components and the power connector.

[0014] This design features an inwardly protruding mounting platform inside the slot, which supports electromagnetic isolation between the circuit components and the power connectors, provides a stable mounting structure, and does not affect the installation space inside the power supply housing, thus avoiding interference with the installation of the circuit components.

[0015] In a further embodiment, the water-cooled plate includes a bottom cover, a top cover, and a seal. The outer side of the bottom cover is recessed inward to form a groove, and the inner side is close to the circuit assembly. The top cover is fitted onto the groove of the bottom cover by the seal to form the cavity of the water-cooled tank.

[0016] This solution features a water-cooled plate with a bottom cover, a top cover, and seals. The seals ensure the sealing stability of the liquid cooling system. The separate bottom and top covers simplify the production process and reduce equipment costs. The flow channel design is flexible and efficient, the overall structure is strong, and the sealing reliability is excellent. It also provides the possibility of detachable fault inspection, which facilitates the installation and maintenance of power connectors (such as live and neutral wires) and improves the maintenance convenience of the power supply unit.

[0017] In a further embodiment, the bottom of the water-cooling tank is provided with at least one guide block; the guide block extends radially along the bottom cover and is parallel to the water-cooling tank, and divides the cavity of the water-cooling tank into at least two liquid flow channels.

[0018] This solution uses guide blocks to divide the water-cooling tank into at least two liquid flow channels. By physically dividing the flow channels, the coolant is forced to flow through all areas of the entire heat dissipation surface to optimize the flow field distribution and thus maximize heat dissipation performance.

[0019] In a further embodiment, an inlet is installed at one end of the back of the bottom cover and an outlet is installed at the other end; liquid flow holes are formed through the bottom of both ends of the water cooling tank, which are connected to the inlet and the outlet; the inlet and the outlet are connected to the water cooling tank through the liquid flow holes.

[0020] In a further embodiment, the upper part of the groove edge of the water-cooling tank is recessed inward to form an L-shaped stepped structure, and the L-shaped stepped structure is sealed and fitted with the face cover by the sealing element.

[0021] This design incorporates an L-shaped stepped structure to assist in the closing of the bottom and top covers, thereby improving the stability of the closing mechanism.

[0022] In a further embodiment, the bottom cover is made of metal material, and several fixing holes are evenly distributed on its side.

[0023] This solution uses a metal base cover to isolate internal and external electromagnetic interference, reduce the impact of electromagnetic interference generated by power connectors on other components, and improve the overall shielding performance of the power supply in conjunction with the overall shielding function of the housing.

[0024] In a further embodiment, the seal includes a sealing strip.

[0025] This utility model also provides a composite protective chassis, including a power supply housing and a water-cooling device as described above. The water-cooling device includes at least one set of water-cooling plates. The water-cooling plates are encapsulated on the power supply housing as side plates and form a shielding cavity with the power supply housing. Circuit components are installed in the shielding cavity. The top and / or bottom of the water-cooling plates are recessed and embedded with power connectors, so that the power connectors are spatially isolated from the circuit components, shielding the electromagnetic interference generated by the power connectors, and performing heat dissipation through heat exchange with the circuit components and the power connectors.

[0026] The composite protective enclosure designed in this basic scheme uses a water-cooled plate as a side plate encapsulated on the power supply housing, forming a shielded cavity with the power supply housing. The circuit components are installed inside the shielded cavity, giving it both good protection and water-cooling functions. It can provide reliable protection and effective heat dissipation for the internal circuit components, effectively improving the device's anti-interference performance and stability, ensuring the normal operation of the power supply in various environments, and thus ensuring the power supply's working efficiency.

The embodiments are given for illustrative purposes only and should not be construed as limiting the utility model. The accompanying drawings are for reference and illustration only and do not constitute a limitation on the scope of patent protection of this utility model, because many changes can be made to this utility model without departing from the spirit and scope of this utility model.

[0029] This utility model provides a water cooling device, such as... Figure 1 As shown, in this embodiment, it includes: A water-cooled plate A has a cavity inside to form a water-cooled tank 4, which is filled with coolant. Power connector B, the main body of which is recessed and embedded in the water-cooled plate A, is spatially isolated from the circuit assembly D. One end is connected to an external device, and the other end is electrically connected to the power supply terminal of the circuit assembly D. The water-cooled plate A is close to the side of the circuit assembly D and in close contact with the power connector B for heat exchange and heat dissipation. It also uses its own shell to separate the power connector B from the circuit assembly D and shield the electromagnetic interference generated by the power connector B.

[0030] The power connector B includes a neutral wire and a live wire. The circuit component D (e.g., the EMC board) can be placed at a remote location, optimizing the internal layout of the power supply, facilitating the installation and maintenance of internal components, and also allowing the EMC board to better perform its electromagnetic compatibility performance.

[0031] In this embodiment, the top and / or bottom of the water-cooled plate A are provided with a wire groove 5. The wire groove 5 is recessed inward to form a sunken strip groove. The strip groove extends radially and is parallel to the flow direction of the water-cooled groove 4. Both ends open inward to connect to the power connector B. The depth of the groove 5 is greater than the diameter of the power connector B.

[0032] In this embodiment, a recessed strip groove is provided to fully isolate the power connector B from the circuit assembly D, blocking the direct path of noise radiation and crosstalk through space. The depth of the groove 5 is greater than the diameter of the power connector B, completely concealing the power connector B within the water-cooled plate A, while preventing the intrusion of liquids and foreign objects, effectively protecting the power connector B and the circuit assembly D from corrosion.

[0033] In this embodiment, a fixing platform 6 is constructed by protruding inward from the inner side of the cable tray 5. The top surface of the fixing platform 6 has a plurality of fixing holes 61 evenly distributed, and its platform height is flush with that of the water-cooled plate A. The water-cooled plate A is mounted on the power supply housing B as a side plate through the fixing holes 61. The fixing platform 6, the power supply housing B, and the inner sidewall of the water-cooled plate A form a shielding cavity, thereby isolating the shielding cavity from the central area of ​​the cable tray 5 and performing electromagnetic isolation between the circuit assembly D and the power connector B.

[0034] In this embodiment, a fixing platform 6 is constructed by protruding inward from the inner side of the online slot 5. On the one hand, it supports the electromagnetic isolation between the circuit component D and the power connector B, and on the other hand, it provides a stable installation structure without affecting the installation space inside the power housing B, thus avoiding interference with the installation of the circuit component D.

[0035] In this embodiment, the water-cooled plate A includes a bottom cover 1, a top cover 2, and a sealing element 3. The outer side of the bottom cover 1 is recessed inward to form a groove, and the inner side is close to the circuit assembly D. The top cover 2 covers the groove of the bottom cover 1 through the sealing element 3 to form the cavity of the water-cooled tank 4.

[0036] In this embodiment, the bottom cover 1 is made of a metal material (such as copper or aluminum alloy), and a plurality of fixing holes 61 are evenly distributed on its side.

[0037] In this embodiment, the bottom cover 1 is made of metal material to isolate internal and external electromagnetic interference, reduce the impact of electromagnetic interference generated by the power connector B on other components, and improve the overall shielding performance of the power supply in conjunction with the overall shielding function of the housing.

[0038] The faceplate 2 can be made of high-strength alloy material (such as aluminum alloy) or metal material with good electrical conductivity (such as copper). A sealing element 3 is provided between the faceplate 2 and the bottom cover 1 to ensure that the protective and shielding performance of the water cooling tank 4 is not affected. The faceplate 2 is provided with a fixing device, such as screws or buckles (which can be set to be detachable as needed), to firmly fix the cover plate to the bottom cover 1.

[0039] This embodiment features a water-cooled plate A comprising a bottom cover 1, a top cover 2, and a sealing element 3. The sealing element 3 ensures the sealing stability of the liquid cooling heat dissipation. The separate bottom cover 1 and top cover 2 simplify the production process and reduce equipment costs. The flow channel design is flexible and efficient, the overall structure is strong, and the sealing reliability is excellent. At the same time, it provides the possibility of detachable fault inspection, which facilitates the installation and maintenance of power connectors B (such as live and neutral wires), and improves the maintenance convenience of the power supply device.

[0040] In this embodiment, the bottom of the water-cooled tank 4 is provided with at least one guide block 41; the guide block 41 extends radially along the bottom cover 1 and is parallel to the water-cooled tank 4, and divides the cavity of the water-cooled tank 4 into at least two liquid flow channels.

[0041] Alternatively, in other embodiments, guide block 41 may be provided as needed.

[0042] In this embodiment, a guide block 41 is set to divide the water-cooling tank 4 to form at least two liquid flow channels. By physically dividing the flow channels, the coolant is forced to flow through all areas of the entire heat dissipation surface to optimize the flow field distribution and thus maximize the heat dissipation performance.

[0043] In this embodiment, a water inlet 11 is installed at one end of the back of the bottom cover 1 and a water outlet 12 is installed at the other end; liquid flow holes 42 are formed through the bottom of both ends of the water cooling tank 4, which are connected to the water inlet 11 and the water outlet 12; the water inlet 11 and the water outlet 12 are connected to the water cooling tank 4 through the liquid flow holes 42.

[0044] In this embodiment, the upper part of the groove edge of the water-cooling tank 4 is recessed inward to form an L-shaped stepped structure, and the L-shaped stepped structure is sealed and fitted with the face cover 2 by the sealing member 3.

[0045] In this embodiment, an L-shaped stepped structure is used to assist in the closing of the bottom cover 1 and the top cover 2, thereby improving the stability of the closing.

[0046] In this embodiment, the sealing element 3 includes an injection-molded sealing strip.

[0047] This embodiment of the invention features a water-cooled plate A positioned close to the side of the circuit assembly D. Replacing the side plate of the power supply housing B with the water-cooled plate A, it provides both waterproofing and dustproofing while simultaneously offering liquid cooling, thus facilitating the miniaturization of the device and effectively improving its operating efficiency. Furthermore, the improved water-cooled plate A incorporates a recessed and embedded power connector B. This not only allows for simultaneous heat dissipation of the power connector B but also isolates it from the circuit assembly D through its own housing, shielding it from electromagnetic interference generated by the power connector B. This provides a stable operating environment, improves circuit stability, and ultimately ensures the normal operation of the power supply device.

[0048] Example 2 This utility model embodiment also provides a composite protective chassis, including a power supply housing B and a water-cooling device as described above. The water-cooling device includes at least one set of water-cooling plates A. The water-cooling plates A are encapsulated on the power supply housing B as side plates (modularly installed through fixing holes 61) and form a shielding cavity with the power supply housing B. A circuit assembly D is installed in the shielding cavity. The top and / or bottom of the water-cooling plates A are recessed and embedded with a power connector B, so that the power connector B is spatially isolated from the circuit assembly D, shielding the electromagnetic interference generated by the power connector B, and performing heat dissipation through heat exchange with the circuit assembly D and the power connector B.

[0049] The power supply housing B is made of high-strength alloy material (such as aluminum alloy) or metal material with good conductivity (such as copper). Each connection part of the power supply housing B is equipped with sealing strips to achieve the purpose of dustproof, waterproof, vibration-proof and impact-proof.

[0050] Alternatively, in other embodiments, the inner wall of the power supply housing B is provided with an electromagnetic shielding coating, and the various components of the power supply housing B are electrically connected to form a complete shield to effectively isolate internal and external electromagnetic interference.

[0051] In this embodiment, the power supply housing B includes a rear cover, which has a water injection hole and an input interface and an output interface for installing wiring terminals; the water injection hole is connected to the water cooling tank 4.

[0052] In this embodiment, one or two sets of water-cooled plates A can be set up for heat dissipation as needed, for example: When only one set of water-cooled plates A is installed, the power supply housing B includes a front cover 7, a rear cover 8, an upper shell 9, a bottom shell 10, and side plates. To support liquid cooling circulation, water injection holes are provided on both the front cover 7 and the rear cover 8 (water-cooled pipes pass through the water injection holes and are connected to the external water-cooling system). Water enters through the front cover 7 and exits through the rear cover 8 (or water exits through the front cover 7 and enters through the rear cover 8). The water-cooled plates A are connected to the external water-cooling system through water-cooled pipes.

[0053] The water-cooled pipes are made of corrosion-resistant and thermally conductive materials, such as copper or stainless steel.

[0054] See Figure 5 , Figure 6 , Figure 7 When two sets of water-cooled plates A are installed, the power supply housing B includes a front cover 7, a rear cover 8, an upper shell 9, and a bottom shell 10. To support liquid cooling circulation, two water injection holes are provided on the rear cover 8, one for water inlet and one for water outlet, and connected to an external water cooling system through a water cooling pipe. At the same time, the two sets of water-cooled plates A are connected to each other through a water inlet 11 and a water outlet 12 on the bottom cover 1 (with a hose or connector in between).

[0055] In other embodiments, a mounting window may be provided in the front cover 7 as needed to mount the input / output terminals of the circuit assembly D.

[0056] Specifically: In the OCP power supply of the computing server, the front end of the power supply device is the input and output terminals that are connected to the computing server, and the rear end is equipped with water injection holes to assist the water cooling plate A for liquid cooling circulation.

[0057] At this time, the high-frequency noise generated by the primary and secondary circuits in the circuit component D of the power supply device and the electromagnetic interference generated by the power connector B (neutral wire and live wire) are isolated by the fixed platform 6 on the water-cooled plate A. The secondary circuit can then be placed in the rear area, close to its output terminal (the secondary circuit outputs power through the output copper busbar or output connector instead of through wires), thereby meeting the output requirements of high current (e.g., 200A or 400A) and high power (e.g., 12KW).

[0058] The composite protective enclosure provided in this embodiment of the utility model uses a water-cooled plate A as a side plate encapsulated on the power supply housing B, forming a shielded cavity with the power supply housing B. The circuit component D is installed inside the shielded cavity, which enables it to have both good protection and water-cooling heat dissipation functions. It can provide reliable protection and effective heat dissipation for the internal circuit component D, effectively improve the anti-interference performance and stability of the device, ensure the normal operation of the power supply in various environments, and thus ensure the working efficiency of the power supply.

[0059] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
