Description

Technical Field

[0001] The present invention relates to the technical fields of power supply and heat dissipation, and in particular to a power supply device and a server system. Background Art

[0002] Power supply technology for servers, especially redundant power supply technology, has become increasingly mature. Server power supply issues have long been a key technical focus, and with the explosive growth of data volumes, high-density blade servers are becoming increasingly widespread. However, stable server operation depends not only on the reliability of the power supply system but also on its heat dissipation efficiency. This interplay between the two has become a major bottleneck restricting performance improvements.

[0003] In actual operating environments, high-density servers are usually deployed in centralized cabinets and equipped with cooling systems. For high-density servers, if the cooling effect in the cabinet is poor, it will have a serious impact on the server's operating performance. Currently, enhanced cooling systems usually have independent power supplies. During long-term operation, these independent power supplies are prone to failure. For example, the power supply effect of the power supply will be affected in high-temperature environments, resulting in unstable current and voltage. This makes it difficult for the cooling system to reach the rated power supply or power fluctuations occur, and the actual cooling effect cannot achieve the expected control target. On the other hand, the long-term operation of the power supply will generate additional heat sources in the server cabinet, which is extremely detrimental to the server's operating environment, making it difficult to effectively reduce the overall computer room temperature, further affecting the performance and stability of the server.

[0004] Therefore, there is an urgent need to develop a power supply device that can solve key technical problems such as the power supply being prone to failure during long-term operation and becoming an additional heat source, so as to meet the performance stability of electrical equipment and the temperature control of the working environment. Summary of the Invention

[0005] The present invention provides a power supply device and a server system to at least solve the technical problem in the related art that the power supply fails and generates heat during long-term operation, thereby causing unstable operation of power-consuming equipment such as servers due to overheating of the working environment.

[0006] The present invention provides a power supply device, comprising a sliding support seat, two power supply units and a drive assembly. The sliding support seat is arranged on a mounting platform; the two power supply units are slidably arranged on the sliding support seat, the two power supply units are connected side by side in the sliding direction, and are alternately in the power supply position by reciprocating sliding; the drive assembly comprises two heat dissipation substrates, respectively arranged on the two power supply units, the two heat dissipation substrates are provided with cavities and filled with thermal expansion medium, and also comprises two force-applying mechanisms, which are arranged on opposite sides of the two heat dissipation substrates and are connected to the corresponding cavities; wherein, when the temperature of the power supply unit working in the power supply position exceeds a threshold value, the adjacent thermal expansion medium expands, driving the force-applying mechanism to move the working power supply unit out of the power supply position, and the idle power supply unit moves into the power supply position, thereby realizing power supply switching.

[0007] The present invention also provides a server system, including a server cabinet, multiple servers, a basic heat dissipation component, a reinforced heat dissipation component, a base and the above-mentioned power supply device; multiple servers are arranged in the above-mentioned server cabinet; the basic heat dissipation component is arranged on the top of the above-mentioned server cabinet; the reinforced heat dissipation component is arranged on the side wall of the above-mentioned server cabinet; the base is spaced apart from the above-mentioned server cabinet; the above-mentioned power supply device is arranged on the above-mentioned base and is configured to supply power to the above-mentioned reinforced heat dissipation component.

[0008] The present invention utilizes the thermal expansion characteristics of a thermally expansive medium in combination with a combined arrangement of a force-applying mechanism to achieve automatic switching of the power supply state of the power supply unit based on its own operating temperature, effectively resolving the issue of reduced reliability of conventional power supply devices in high-temperature environments. Heat generated by the active power supply unit is transferred to the thermally expansive medium, causing its thermal expansion to drive the force-applying mechanism to move the active power supply unit and the idle working unit between the active position and the idle positions on either side, switching the power supply between the power supply units. This not only ensures continuous and stable power supply, but also reduces the continuous operating temperature of a single power supply unit through alternating operating modes, thereby improving the reliability and service life of the overall system while avoiding power interruptions during redundant power supply switching.

[0060] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and are therefore not to be construed as limiting the present invention. The terms "mounted," "connected," and "connected" should be broadly construed, and may include, for example, fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. The terms "parallel," "perpendicular," and "equal" encompass the conditions described and conditions similar to the conditions described, provided that the range of the similar conditions is within an acceptable range of deviation, as determined by one of ordinary skill in the art taking into account the measurement in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes both absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism may be, for example, within 5°; "perpendicular" includes both absolute perpendicularity and approximate perpendicularity, where the acceptable deviation range for approximate perpendicularity may also be, for example, within 5°.

Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific circumstances.

[0062] The power supply of servers has always been a technical direction that people pay close attention to. The current power supply technology of servers, including redundant power supply, has become increasingly mature. However, servers are usually accompanied by cabinets and additional enhanced cooling systems. For high-density blade servers, if the cooling effect in the cabinet is not strong, this will have a significant impact on the operating performance of the server. Therefore, the internal cooling effect is equally important for servers, but it is often overlooked. Enhanced cooling systems usually have additional independent power supplies. However, due to the long-term operation of the cooling equipment, once the independent power supply of the cooling equipment fails, such as high temperature, it affects the actual power supply effect, resulting in unstable current and voltage, which in turn makes it difficult for the cooling fan to reach the actual power supply, or power fluctuations occur, resulting in fan speed and cooling effect weaker than the actual control desired cooling effect. In addition, the long-term operation of the additional power supply will also lead to additional heat sources in the server cabinet, which is not conducive to the server's operating environment and makes it difficult to reduce the overall temperature of the computer room.

[0063] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0064] Figure 1 A three-dimensional structural diagram of a power supply device provided in an embodiment of the present invention; Figure 2 This is a structural diagram of a heat dissipation substrate provided in an embodiment of the present invention.

[0065] An embodiment of the present invention provides a power supply device, such as Figure 1 and Figure 2 As shown, the power supply device includes: a sliding support base 1, two power supply units 2 and a driving assembly 3. The sliding support base 1 is set on the installation platform; the two power supply units 2 are slidingly set on the sliding support base 1, the two power supply units 2 are connected side by side in the sliding direction, and are alternately in the power supply position by reciprocating sliding; the driving assembly 3 includes two heat dissipation substrates 31 and two force-applying mechanisms 32, the two heat dissipation substrates 31 are respectively set on the two power supply units 2, the two heat dissipation substrates 31 are provided with cavities 311 and filled with thermal expansion medium, the two force-applying mechanisms 32 are set on the opposite sides of the two heat dissipation substrates 31, and are connected with the corresponding cavities 311; wherein, when the temperature of the power supply unit 2 working in the power supply position exceeds the threshold value, the adjacent thermal expansion medium will be expanded, and the driving force-applying mechanism 32 will drive the working power supply unit 2 to move out of the power supply position, and the idle power supply unit 2 to move into the power supply position, thereby realizing power supply switching.

[0066] According to the above-described configuration, a thermal expansion-driven mechanism enables automatic switching of power supply units 2 triggered by temperature changes. The heat generated by the operating power supply unit 2 causes the thermal expansion medium to expand, thereby driving the force-applying mechanism 32 to cause the two power supply units 2 to interchange in their power supply positions. This not only ensures continuous and stable power supply but also reduces the continuous operating temperature of a single power supply unit 2 through alternating operating modes. This mechanical, temperature-responsive switching method avoids the delays associated with traditional electronic switching circuits, enabling fast and reliable power switching. It also simplifies the system architecture and improves the reliability and service life of the overall power supply system.

[0067] According to an embodiment of the present invention, the heat dissipation substrate 31 is attached to a portion of the power supply unit 2 that is prone to heat generation, and a heat conductive member is provided between the heat dissipation substrate 31 and the power supply unit 2 to quickly conduct the heat generated by the heat generating portion during operation to the thermal expansion medium in the cavity 311 of the heat dissipation substrate 31.

[0068] Specifically, the heat sink 31 is tightly adhered to the surface of key heat-generating components, such as the power components, of the power supply unit 2 using highly thermally conductive silicone grease. A thermally conductive member, such as a copper thermal pad, is positioned between the two, acting as a highly efficient heat-conducting medium. This three-layer thermal structure (heat-generating surface of the power supply unit 2 - thermally conductive member - heat sink 31) enables rapid heat transfer, rapidly transferring the heat generated by the power supply unit 2 during operation to the thermally expanding medium within the cavity 311 of the heat sink 31.

[0069] According to embodiments of the present invention, the thermal expansion heat transfer medium can be a variety of liquid media with high thermal expansion properties, including but not limited to: organic silicone oils, such as methyl silicone oil or phenyl silicone oil; liquid metal alloys, such as gallium-based alloys or indium-based alloys; mineral oils, such as white oil or transformer oil; and specially formulated synthetic esters. These media can be selected based on the temperature range and expansion property requirements of the specific application scenario. A combination of these media can also be used to achieve even better thermal response performance.

[0070] According to an embodiment of the present invention, the two heat dissipation substrates 31 are integrally formed, and two cavities 311 are formed inside at the installation position of the power supply unit 2. An insulation layer is provided between the two cavities 311 to prevent the thermal expansion media in the two cavities 311 from conducting heat to each other and affecting the driving effect.

[0071] Figure 3 A side view of a power supply device provided in an embodiment of the present invention.

[0072] In an illustrative embodiment, Figure 1 and Figure 3As shown, a wireless transmission module 21 is provided at the end of each power supply unit 2, and the power supply unit 2 is configured so that when the power supply unit 2 moves to the power supply position, the wireless transmission module 21 couples with the power receiving module of the power-consuming device to realize power supply.

[0073] Specifically, the power supply unit 2 achieves seamless power transmission during the switching process by coupling the wireless transmission module 21 with the power receiving module of the power-consuming device. When the temperature of the working power supply unit 2 exceeds a threshold, the thermal expansion medium expands and drives the force-applying mechanism 32, causing the currently working power supply unit 2 to move out of the power supply position along the sliding support base 1, while the idle power supply unit 2 is synchronously moved into the power supply position. During this switching process, the wireless transmission module at the end of the power supply unit 2 that has moved into the power supply position automatically aligns with the power receiving module of the power-consuming device, establishing a power connection through electromagnetic induction coupling, while the power supply unit 2 that has moved out of the power supply position disconnects the power supply connection.

[0074] According to the above-mentioned setting method, the combination of mechanical displacement and wireless power supply ensures the continuity of power transmission during the power supply switching process, avoiding the arc and voltage fluctuation problems that may be caused by traditional contact switching.

[0075] In an illustrative embodiment, Figure 1 and Figure 3 As shown, the sliding support base 1 includes a slide rail 11, two mounting bases 12, and a connecting plate 13. The two ends of the slide rail 11 are parallel to the mounting platform through the mounting bases 12, and the end of the connecting plate 13 is provided with a sliding portion 131 that cooperates with the slide rail 11; wherein, the two power supply units 2 are arranged side by side on the upper surface of the connecting plate 13.

[0076] According to the above-mentioned configuration, the sliding support base 1 realizes smooth and reliable reciprocating sliding switching of the power supply unit 2 through the coordinated design of the sliding rail 11 and the connecting plate 13 .

[0077] Specifically, the parallel slide rails 11 and the sliding portion 131 of the connecting plate 13 form a precise guiding fit, ensuring that the two power supply units 2 maintain precise linear motion trajectories during the switching process; the rigid fixed connection of the mounting seat 12 ensures the stability of the overall structure, so that the power supply unit 2 will not deviate or shake during repeated switching; the connecting plate 13 installs two power supply units 2 at the same time to ensure that the switching movement remains consistent.

[0078] According to an embodiment of the present invention, the connection plate 13 and the heat dissipation substrate 31 are integrally formed.

[0079] Figure 4 A cross-sectional view of a power supply device at a force-applying mechanism according to an embodiment of the present invention.

[0080] In an illustrative embodiment, Figure 1 andFigure 4 As shown, the force-applying mechanism 32 includes a piston cylinder 321, a sealing piston 322, and a guide channel 323. The piston cylinder 321 extends in a sliding direction; the sealing piston 322 is slidably disposed within the piston cylinder 321; and the guide channel 323 connects the cavity 311 of the heat dissipation substrate 31 with the inner cavity of the piston cylinder 321. The thermal expansion medium expands due to heat, passing through the guide channel 323 and driving the sealing piston 322 to move linearly along the piston cylinder 321.

[0081] According to the above arrangement, the switching action of the power supply unit 2 is controlled by the mechanical transmission design in which the piston is driven by the thermal expansion medium.

[0082] Specifically, when the operating temperature of the power supply unit 2 rises, the thermal expansion medium in the cavity 311 of the heat dissipation substrate 31 expands due to the heat. The expansion pressure is transmitted to the piston cylinder 321 through the guide channel 323, pushing the sealing piston 322 to produce a linear displacement. The linear motion of the sealing piston 322 is converted into a sliding driving force for the power supply unit 2 through mechanical connectors such as fixings, driving the two power supply units 2 to complete the movement and realize the switching of the power supply units 2 in the power supply position. This mechanical force-applying mechanism 32 has the characteristics of fast response, stable drive, and high reliability. It can achieve temperature-triggered automatic switching without the need for additional power supply or control circuit, and is suitable for long-term stable operation in harsh environments such as high temperature and high electromagnetic interference.

[0083] Figure 5 A three-dimensional structural diagram of a fixing mechanism provided in an embodiment of the present invention; Figure 6 A structural diagram of a power supply device showing a cross-section of the fixing mechanism provided in an embodiment of the present invention.

[0084] In an illustrative embodiment, Figure 1 、 Figures 3-6 As shown, the drive assembly 3 also includes a fixing mechanism 33, which includes a fixing seat 331, two guide sleeves 332, and two elastic members 333. The fixing seat 331 is arranged on the mounting platform, and the upper surface of the fixing seat 331 is slidably engaged with the lower surface of the connecting plate 13; the two guide sleeves 332 are symmetrically arranged on the fixing seat 331 and extend along the sliding direction, and the piston cylinder 321 is coaxially sleeved within the corresponding guide sleeve 332; the two elastic members 333 are respectively arranged between the two guide sleeves 332 and the corresponding sealing piston 322; wherein, the linear motion of the sealing piston 322 compresses the elastic member 333, and when the thermal expansion medium cools and contracts, the elastic member 333 applies a reset force to the sealing piston 322.

[0085] According to the above-mentioned setting method, the guide sleeve 332 provides precise axial guidance for the piston cylinder 321. In the process of the thermal expansion medium expanding and driving the sealing piston 322 to move linearly along the piston cylinder 321, it is necessary to overcome the elastic force of the elastic member 333 to do work, so that the piston cylinder 321 moves in the guide sleeve 332 along the direction of movement of the sealing piston 322, driving the heat dissipation substrate 31 and the working power supply unit 2 away from the power supply position, thereby realizing power supply switching.

[0086] Specifically, the elastic member 333 stores elastic potential energy during the movement of the sealing piston 322. When the temperature of the power supply unit 2 decreases and the thermal expansion medium contracts, the elastic member 333 releases its own elastic potential energy and the elastic potential energy stored during compression to push the sealing piston 322 back to its original position, preparing for the next switching action. Furthermore, the sliding fit between the fixing seat 331 and the connecting plate 13 further enhances the overall stability of the system, effectively preventing vibration and deviation during the switching process.

[0087] In an illustrative embodiment, Figure 5 and Figure 6 As shown, the fixing seat 331 includes a base 3311, a protection groove 3312 and a fixing portion 3313. The base 3311 is provided with a protection groove 3312 extending along the sliding direction; the fixing portion 3313 is provided in the middle of the protection groove 3312, and two guide sleeves 332 are symmetrically provided on both sides of the fixing portion 3313.

[0088] Specifically, the design of the protective groove 3312 extending along the sliding direction provides movement space and effective mechanical protection for the force-applying mechanism 32, while ensuring that the sliding trajectory of the connecting plate 13 is not disturbed. The layout of the fixing portion 3313 located in the middle of the protective groove provides a symmetrical support structure for the two guide sleeves 332, ensuring that the movement axis of the piston cylinder 321 is strictly parallel to the sliding direction of the power supply unit 2. This effectively prevents foreign matter from entering the gap between the moving parts, improving the reliability of the power supply device in harsh environments.

[0089] Figure 7 A side view of an adjustment mechanism provided in an embodiment of the present invention; Figure 8 A schematic diagram of the bottom of a connecting plate provided in an embodiment of the present invention.

[0090] In an illustrative embodiment, Figure 3 、 Figure 7 and Figure 8As shown, the drive assembly 3 also includes a limiting mechanism 34, which includes an elastic sheet 341. The two ends of the elastic sheet 341 are arranged in the fixing seat 331, and the middle part is bent to form a snap-fitting protrusion 3411 protruding from the upper surface of the fixing seat 331; two limiting holes 132 are set at the bottom of the connecting plate 13, and the two limiting holes 132 correspond to the positions of the two power supply units 2; wherein, the snap-fitting protrusion 3411 and the limiting hole 132 form a detachable snap-fitting fit, and when the driving force applied to the connecting plate 13 exceeds a preset threshold, the snap-fitting protrusion 3411 disengages from the limiting hole 132.

[0091] According to an embodiment of the present invention, the limiting mechanism 34 is disposed in the middle of the fixing seat 331 , and the two limiting holes 132 are respectively disposed on the connecting plate 13 directly below the power supply unit 2 .

[0092] According to the above-mentioned configuration, the working position of the power supply unit 2 is accurately positioned and reliably maintained through the snap-fit ​​design between the elastic piece 341 and the limiting hole 132 .

[0093] Specifically, the elastic piece 341 is fixed at both ends, and its upwardly curved center forms a latching protrusion 3411, which forms a stable latching connection with the retaining hole 132 of the connecting plate 13 under normal conditions. This ensures that the power supply unit 2 is accurately locked in the working position and prevents accidental displacement due to vibration or external forces. When the driving force generated by the linear motion of the sealing piston 322 compressing the elastic member 333 exceeds the latching force threshold, the latching protrusion 3411 can be disengaged from the retaining hole 132, allowing the connecting plate 13 to slide smoothly and complete the switching action. This mechanical positioning mechanism has the characteristics of simple structure, high positioning accuracy, and no need for external energy.

[0094] According to an embodiment of the present invention, the elastic piece 341 is constructed as an overall V-shaped symmetrical structure, specifically comprising a pair of symmetrically arranged elastic segments, the bottom ends of which are securely mounted in the mounting grooves of the fixing seat 331 via fixed ends, and an arcuate transition segment connecting the top ends of the two elastic segments, forming an overall structure with a hemispherical engaging protrusion 3411. When the horizontal driving force applied to the connecting plate 13 exceeds a set threshold, the engaging protrusion 3411 and the contact surface of the limiting hole 132 undergo relative displacement.

[0095] Specifically, the engaging protrusion 3411 is subjected to an oblique force from the edge of the retaining hole 132, which is broken down into vertical and horizontal components. The vertical force causes the elastic segments on both sides to simultaneously bend inward, while the horizontal force forces the engaging protrusion 3411 to slide out along the sidewalls of the retaining hole 132. During this process, the symmetry of the V-shaped structure ensures that the elastic segments on both sides deform synchronously, avoiding unilateral stress concentration. Once the position switch is completed, the restoring force of the elastic segments pushes the engaging protrusion 3411 out, engaging with the other retaining hole 132 and forming a new retaining position.

[0096] In one exemplary embodiment, the limiting hole 132 is configured as a tapered flared opening. Specifically, the inclined surface design of the tapered flared opening allows the engaging protrusion 3411 to gradually slide out along the smooth guide surface during disengagement, effectively reducing disengagement resistance. Furthermore, the tapered structure provides a progressive contact pressure distribution for the engaging protrusion 3411, avoiding sudden stress concentration. This ensures both positioning accuracy in the engaged state and smooth movement during switching, thereby enhancing the smoothness and reliability of the engaging protrusion 3411 during disengagement.

[0097] In an illustrative embodiment, Figure 7 As shown, the limiting mechanism 34 also includes an adjustment mechanism 342, which includes a bidirectional screw 3421, a knob 3422, and two movable blocks 3423. The bidirectional screw 3421 is rotatably disposed within the fixed seat 331. One end of the bidirectional screw 3421 extends outside the fixed seat 331 and is provided with the knob 3422. The two movable blocks 3423 are disposed at opposite ends of the elastic sheet 341 and are threadedly connected to the threaded sections of the bidirectional screw 3421 that are symmetrically disposed in opposite directions. The bidirectional screw 3421 drives the two movable blocks 3423 to move toward or away from each other, adjusting the curvature of the elastic sheet 341 to change the clamping force threshold of the clamping protrusion 3411.

[0098] Specifically, rotating knob 3422 rotates bidirectional screw 3421, causing the two movable blocks 3423 to move synchronously in opposite directions. By varying the degree of pressure on both ends of elastic sheet 341, the bending deformation is precisely adjusted, thereby varying the latching force threshold of latching protrusion 3411. This mechanical adjustment mechanism offers high precision and excellent stability. The forward and reverse thread design of bidirectional screw 3421 ensures symmetrical movement of the two movable blocks 3423, evenly applying force to elastic sheet 341. The adjustment process requires no disassembly of any components; latching force can be adjusted simply by turning an external knob, meeting the requirements of various operating conditions.

[0099] Furthermore, adjustment mechanism 342 precisely adjusts the relay engagement threshold of elastic sheet 341 by rotating knob 3422, depending on the actual operating temperature of power supply unit 2. When power supply unit 2 operates at a higher temperature, the relay engagement threshold can be appropriately lowered, allowing the thermally expansive medium to more easily trigger a switching action at the set temperature. Conversely, at lower temperatures, the relay engagement force can be increased to prevent erroneous switching. This mechanical adjustment mechanism precisely adjusts the curvature of elastic sheet 341 to the temperature characteristics of power supply unit 2.

[0101] The embodiment of the present invention also provides a server system, such as Figures 9-11 As shown, it includes a server cabinet 4, multiple servers 5, a reinforced heat dissipation component 6, a base 7 and a power supply device. Multiple servers 5 are arranged in the server cabinet 4; the reinforced heat dissipation component 6 is arranged on the side wall of the server cabinet 4; the base 7 is spaced apart from the server cabinet 4; the power supply device is arranged on the base 7 and is configured to supply power to the reinforced heat dissipation component 6.

[0102] According to the above-mentioned setting method, the power supply device is independently set on the base 7 and maintains a reasonable distance from the server cabinet 4, which not only ensures the heat dissipation conditions of the power supply device itself, but also avoids the temperature rise problem inside the cabinet caused by the traditional built-in power supply method; the power supply device provides a stable and reliable power supply for the enhanced heat dissipation component 6 through an optimized thermal expansion driven switching mechanism. When the working power supply unit 2 is detected to have an abnormal temperature, it can quickly and automatically switch to the restricted power supply unit 2 to ensure the continuous and stable operation of the heat dissipation system.

[0103] In an illustrative embodiment, Figure 9 and Figure 10 As shown, multiple servers 5 are arranged horizontally in the server cabinet 4 at intervals along the vertical direction, and a heat dissipation duct is formed between two adjacent servers 5; the enhanced heat dissipation component 6 includes multiple heat dissipation fan groups 61, which are arranged at intervals facing the heat dissipation duct.

[0104] Specifically, multiple servers 5 are arranged vertically and spaced apart, creating a uniform cooling duct between adjacent servers 5. The cooling fan group 61 of the reinforced heat dissipation assembly 6 is positioned directly opposite the cooling duct, creating a directional airflow path. This layout design allows cooling air to penetrate the heat-generating areas of the servers 5 along the shortest path. At the same air volume, cooling efficiency is improved compared to a traditional, cluttered layout. The spacing of the cooling fan group 61 ensures uniform airflow distribution while preventing interference between fans.

[0105] According to an embodiment of the present invention, Figure 11 As shown, the server system further includes a main power supply module 9 for supplying power to the enhanced heat dissipation assembly 6 , wherein the power supply device is specifically used to supply power to the heat dissipation fan group 61 .

[0106] Specifically, the main power supply module 9 serves as the main power supply, responsible for providing basic power supply for the entire enhanced heat dissipation assembly 6, including power supply for core components such as the control system and monitoring unit; and the power supply device specifically provides working power for the cooling fan group 61, and through its unique dual power supply unit automatic switching mechanism, it ensures that the fan system obtains continuous and stable dedicated power.

[0107] In an illustrative embodiment, Figure 11 As shown, the enhanced heat dissipation assembly 6 further includes a wireless power receiving module 62 , which is disposed on a side of the server cabinet 4 close to the power supply device.

[0108] In detail, the enhanced heat dissipation assembly 6 further includes a power receiving bracket 63 extending from the bottom of the server cabinet 4 , and the wireless power receiving module 62 is disposed on the power receiving bracket 63 , wherein the wireless power receiving module 62 faces the power supply position.

[0109] Specifically, the layout of the power receiving bracket 63 extending from the bottom of the server cabinet 4 maintains an optimal operating distance between the wireless power receiving module 62 and the power supply unit 2 of the power supply device. When either power supply unit 2 moves to the power supply position, its wireless transmission module 21 automatically aligns with the wireless power receiving module 62, forming a highly efficient electromagnetic coupling. This contactless power supply solution eliminates the wiring difficulties associated with traditional cable connections and completely avoids power supply instability caused by loose or oxidized connectors.

[0110] In an illustrative embodiment, Figure 9 and Figure 10 As shown, the server system further includes a basic heat dissipation component 8 , which is disposed on the top of the server cabinet 4 .

[0111] The power supply device and server system provided by the embodiment of the present invention realizes temperature-triggered automatic switching of the power supply unit 2 through an innovative thermo-mechanical linkage design. The complete workflow is as follows:

[0112] Initial power supply phase: The server system boots up. The power supply unit 2, in its operating position, establishes a coupled power connection with the wireless power receiving module 62 of the enhanced heat dissipation assembly 6 via the wireless transmission module 21, providing stable power to the cooling fan assembly 61. During this period, the idle power supply unit 2 is in standby mode, the thermal expansion medium within the heat dissipation substrate 31 remains at room temperature, and the elastic member 333 of the force-applying mechanism 32 is extended. The elastic piece 341 of the retaining mechanism 34, via its engaging protrusion 3411, forms a stable engagement with the retaining hole 132 of the connecting plate 13, ensuring that the power supply unit 2 is accurately positioned in the power supply position.

[0113] Temperature Response Phase: As power supply unit 2 continues operating, heat generated by the heat-generating components is conducted through the heat conductor to the cavity 311 of the heat dissipation substrate 31. The thermal expansion medium expands linearly upon heating, generating expansion pressure that is transmitted through guide channel 323 to the sealing piston 322 of the force-applying mechanism 32, pushing the sealing piston 322 to compress the elastic member 333. This process reflects the temperature changes of power supply unit 2 in real time, and the amount of medium expansion is positively correlated with the temperature increase.

[0114] Critical trigger stage: when the temperature of the working power supply unit 2 reaches the preset threshold value, typically 60℃, the pressure generated by the thermal expansion medium makes the driving force generated by the compression elastic member 333 of the force applying mechanism 32 exceed the clamping force threshold value of the limiting mechanism 34. At this time, the clamping protrusion 3411 of the elastic sheet 341 smoothly comes out of the limiting hole 132, indicating that the mechanical locking state of the connecting plate 13 is released, and the switching condition is completely met.

[0115] Switching execution stage: after the lock is released, the two power supply units 2 are driven by the force applying mechanism 32 to slide along the sliding support seat 1 synchronously. The wireless transmission module 21 of the working power supply unit 2 gradually moves out of the effective coupling range of the wireless power receiving module 62 with displacement, while the wireless transmission module 21 of the limited power supply unit 2 enters the power supply area and establishes connection. The whole switching process takes about 0.5-1 second, realizing seamless switching of power supply.

[0116] Stable running stage: after the switching is completed, the original working power supply unit 2 enters the cooling period, and the volume of the medium in the heat dissipation substrate 31 decreases due to the decrease of the temperature, so that the elastic member 333 pushes the sealing piston 322 to reset, and the force applying mechanism 32 returns to the initial state. The elastic sheet 341 of the limiting mechanism 34 reenters another limiting hole 132 under the preset pressure of the adjusting mechanism 342, maintaining the stable working state of the new power supply unit 2, until the temperature drops to the safety threshold value, usually below 45℃, and the switching condition is met again.
