[0001] The present invention relates to a power supply device module, and particularly to a power supply device module that is easy to assemble and replace.

Background Art

[0002] Currently, with the development of data centers, the power consumption of server hosts is increasing, and the power supply devices attached to server racks are also becoming more powerful.

[0003] However, as the power of the power supply device increases, the heat dissipation requirements for the power supply device also improve. To ensure good heat conduction efficiency, it is necessary to make the power supply device and the water cooling plate closer, but this close contact also causes inconvenience when attaching and detaching the power supply device.

[0004] Therefore, proposing a power supply device module that can effectively solve the above problems is one of the problems that need to be solved in the current industry.

[0014] In one or more embodiments of the present invention, a power supply module is a power supply module mounted in a server rack and comprises a first water-cooled plate, a power supply device, a first handle, a second water-cooled plate, and a second handle. The power supply device is provided on the first water-cooled plate. The first handle includes two first connecting arms and a first gripping portion. The two first connecting arms are connected to opposing sides of the power supply device. The first gripping portion connects the two first connecting arms. The second water-cooled plate is provided on the power supply device.

[0015] In one or more embodiments of the present invention, the power supply module further comprises a second handle including two second connecting arms connected to opposing sides of a second water cooling plate, and a second gripping portion connecting the two second connecting arms.

[0017] In one or more embodiments of the present invention, the power supply module further comprises an engaging member. The second water cooling plate includes a latch hole. The second frame has a lock hole. The engaging member is inserted into the latch hole and engages with the lock hole.

[0018] In one or more embodiments of the present invention, there is one first water cooling plate, and there are two second water cooling plates.

[0019] In one or more embodiments of the present invention, a power supply module provided in a server rack comprises a first water-cooled plate, a plurality of power supply devices, and a plurality of second water-cooled plates.

[0024] Several embodiments of the present invention are disclosed below with reference to the drawings. For clarity, many practical details are also described below. However, it should be understood that these practical details are not intended to limit the disclosure. In other words, in some embodiments of the disclosure, these practical details are not necessary. Also, for the sake of simplification of the drawings, certain conventional structures and elements are shown simply and schematically in the drawings.

[0025] To help readers more clearly understand the relationships and orientations between each element, the diagrams show the coordinate axes X as the first direction, Y as the second direction, and Z as the third direction. Furthermore, the first direction X, the second direction Y, and the third direction Z are orthogonal to each other.

[0026] Please refer to Figure 1, a perspective view showing a power supply module 10 according to one embodiment of the present invention. As shown in Figure 1, in this embodiment, the power supply module 10 comprises a water cooling plate 120 and a power supply device 110 that is detachably mounted on the water cooling plate 120. In this embodiment, the power supply module 10 further comprises a handle 130 including two connecting arms 131 and a gripping portion 132 connected to these two connecting arms 131. Specifically, the two connecting arms 131 are each connected to opposing sides of the power supply device 110, and the gripping portion 132 is provided between the two connecting arms 131 and positioned so that an operator can grip it. By applying external force to the gripping portion 132, the operator can move the connecting arms 131 connected to the power supply device 110 in conjunction, thereby completing the assembly and disassembly of the power supply device 110 above the water cooling plate 120.

[0027] As shown in Figure 1, in this embodiment, the handle 130 further includes a hook portion 133. The hook portion 133 extends from at least one of the two connecting arms 131 to the water cooling plate 120 and hooks onto the water cooling plate 120 on the side of the water cooling plate 120 away from the power supply device 110. That is, the water cooling plate 120 may be fitted or clamped between the connecting arms 131 and the hook portion 133, and the hook portion 133 may be provided on both connecting arms 131, or on only one of the connecting arms 131. In this embodiment, the hook portion 133 has a first extension portion 133a and a second extension portion 133b, the first extension portion 133a having one end connected to the connecting arm 131 and the other end connected to the second extension portion 133b. When the connecting arm 131 is positioned substantially parallel to the water cooling plate 120, the first extension 133a extends in the opposite direction to the third direction Z, the second extension 133b extends in the opposite direction to the second direction Y, and the length of the first extension 133a is equal to or slightly greater than the thickness of the water cooling plate 120, so that the water cooling plate 120 is fitted between the first extension 133a and the second extension 133b of the hook portion 133. In this embodiment, when the hook portion 133 hooks onto the other side of the water cooling plate 120 where the power supply device 110 is provided, the water cooling plate 120 is pressed by the second extension 133b, making tight contact with the power supply device 110, thereby achieving better fixation and heat dissipation.

[0028] As shown in Figure 1, in this embodiment, the power supply module 10 further comprises two clamp members 140 provided on the water cooling plate 120, and the side of the power supply 110 away from the handle 130 is positioned to be sandwiched between the two clamp members 140. Specifically, the two clamp members 140 have an elastic deformation capability, and the distance between the two clamp members 140 is slightly smaller than the width D1 of the power supply 110. When an operator places the power supply unit 110 on the water cooling plate 120 and pushes the power supply unit 110 between the two clamp members 140 along the opposite direction of the second direction Y, the two clamp members 140 are pressed and expanded by the power supply unit 110, causing elastic deformation (i.e., the distance between the two clamp members 140 increases). However, when the power supply unit 110 is fixed between the two clamp members 140, the elastic potential energy accumulated by the elastic deformation is released, providing clamping forces on both sides of the power supply unit 110 in the first direction X and the opposite direction of the first direction X, respectively, and fixing the power supply unit 110 to the water cooling plate 120.

[0029] As shown in Figure 1, in this embodiment, the handle 130 further includes a protrusion 134 and two pivot points 135. The protrusion 134 is provided on at least one of the two connecting arms 131 and is positioned to press against the water cooling plate 120. That is, the protrusion 134 may also be provided on both connecting arms 131, or it may be provided on only one of the connecting arms 131 such that the protrusion 134 is located on the side of the connecting arm 131 that faces the water cooling plate 120. Specifically, the protrusion 134 has a pressing surface 134a, and the pressing surface 134a presses against the water cooling plate 120 to detach the power supply device 110 from the water cooling plate 120. In this embodiment, the two connecting arms 131 are each pivotally attached to the power supply device 110 around two pivot points 135. That is, the handle 130 rotates around the power supply device 110 around the two pivot points 135.

[0030] As shown in Figure 1, in this embodiment, when the hook portion 133 catches on the water cooling plate 120, the operator may apply external forces in the second direction Y and the third direction Z to the handle 130 by gripping the grip portion 132 of the handle 130. At this time, the connecting arm 131 rotates around the power supply device 110 with respect to the pivot point 135, moving from a position substantially parallel to the water cooling plate 120 (i.e., the second direction Y) to a position substantially perpendicular to the water cooling plate 120 (i.e., the third direction Z). In this embodiment, since at least one of the two pivot points 135 is provided between the hook portion 133 and the protrusion 134 (similar to a seesaw), as the connecting arm 131 moves continuously, the hook portion 133 detaches from the water cooling plate 120, and the protrusion 134 presses against the water cooling plate 120, separating the power supply device 110 from the water cooling plate 120.

[0031] As shown in Figure 1, in this embodiment, a first fin 111 is provided on the side of the power supply device 110 facing the water cooling plate 120, and a second fin 121 is provided on the side of the water cooling plate 120 facing the power supply device 110. The first fin 111 and the second fin 121 are arranged alternately with respect to each other to increase the contact area between the water cooling plate 120 and the power supply device 110, further improving the heat dissipation efficiency of the power supply device 110, allowing the thermal energy of the power supply device 110 to be conducted from the first fin 111 to the second fin 121, and finally absorbed by the coolant or refrigerant on the water cooling plate 120, carrying away the thermal energy. In this embodiment, the first fin 111 and the second fin 121 are integrally molded or manufactured by aluminum extrusion molding, but the present invention is not limited thereto. In some embodiments, the first fin 111 and the second fin 121 may be manufactured by metal 3D printing, die casting, forging, powder metallurgy, deep drawing, isothermal forging, or a combination thereof.

[0032] As shown in Figure 1, in this embodiment, the power supply module 10 further includes thermal grease 150 filled between the first fin 111 and the second fin 121. Specifically, the thermal grease 150 is uniformly applied to the boundary between the first fin 111 and the second fin 121, filling the minute gaps after the first fin 111 and the second fin 121 are alternately arranged, thereby improving the efficiency of heat conduction. In this embodiment, since the thermal grease 150 can form a strong adhesive layer after solidification, the pressing design of the protrusion 134 allows the operator to lift the power supply 110 through the handle 130 and simultaneously press the water cooling plate 120 through the pressing surface 134a of the protrusion 134, thereby losing the adhesive force of the thermal grease 150 and separating the power supply 110 and the water cooling plate 120.

[0033] Refer to Figure 2, which shows a partial perspective view of the water cooling plate 120 in Figure 1 with the second fin 121 omitted. As shown in Figure 2, and referring to it in conjunction with Figure 1, in this embodiment the water cooling plate 120 includes a slide groove 122 and a ball 123, the slide groove 122 being provided on the side of the water cooling plate 120 facing the power supply device 110. Specifically, when multiple power supply devices 110 are provided on the water cooling plate 120, each surface of the water cooling plate 120 that contacts each power supply device 110 may have two slide grooves 122, each corresponding to opposite sides of a single power supply device 110, but the present invention is not limited thereto. In some embodiments, a single power supply device 110 may correspond to one slide groove 122 or any number of slide grooves 122 on the water cooling plate 120. In this embodiment, the ball 123 is provided so as to be rotatable within the slide groove 122, allowing the power supply device 110 to slide on the water cooling plate 120 via the ball 123, and the slide groove 122 can effectively hold the ball 123 within the slide groove 122 to prevent it from escaping.

[0034] Please refer to Figure 3, a perspective view showing a power supply module 20 according to another embodiment of the present invention. As shown in Figure 3, and referring to it in conjunction with Figure 1, in this embodiment the power supply module 20 differs from the power supply module 10 in that the pivot point 235 of its handle 230 is located on the side of the protrusion 234 away from the gripping portion 232. That is, when separating the power supply 210 and the water cooling plate 220, the operator may first grasp the gripping portion 232 of the handle 230 and apply external force to the handle 230 in the opposite direction of the second direction Y and the opposite direction of the third direction Z. In this case, the two connecting arms 231 rotate around the power supply 210 about the two pivot points 235 and move from a position substantially parallel to the water cooling plate 120 (i.e., the second direction Y) to a position substantially perpendicular to the water cooling plate 120 (i.e., the opposite direction of the third direction Z). The pressing surface 234a of the protrusion 234 continues to press against the water cooling plate 220 during the process of pushing down the handle 230 until the separation of the power supply device 210 and the water cooling plate 220 is complete. After separation, the operator may further pull the power supply device 210 away from the water cooling plate 220 by applying external forces in a second direction Y and a third direction Z to the handle 230.

[0035] Please refer to Figures 4 and 5. Figure 4 is a perspective view showing a power supply module 30 according to another embodiment of the present invention. Figure 5 is a rear perspective view showing the power supply module 30 of Figure 4 with the handle 330 in the open position. As shown in Figures 4 and 5, and referring in conjunction with Figure 1, in this embodiment the power supply module 30 similarly includes a water cooling plate 320 and a power supply device 310 provided on the water cooling plate 320, and similarly includes a handle 330 that can be gripped by an operator. In this embodiment the power supply module 30 differs from the power supply module 10 in that it presses the power supply device 310 directly against the water cooling plate 320 via the connecting arm 331 of the handle 330, rather than completing the fixation of the power supply device 310 and the water cooling plate 320 via its clamp member 140 or hook portion 133.

[0036] As shown in Figures 4 and 5, in this embodiment, the power supply device 310 includes two position regulating parts 312, and the handle 330 includes two connecting arms 331 and gripping parts 332 connected to the two connecting arms 331. The end of each connecting arm 331, away from the gripping parts 332, is fixed to the water cooling plate 320 via a fixing member 340. In other words, the handle 330 is pivotally attached to the water cooling plate 320 with the fixing member 340 as a fulcrum, and can be switched between a closed state (the state shown in Figure 4) and an open state (the state shown in Figure 5). When the handle 330 is in the closed state, the connecting arms 331 press the side of the position regulating part 312 away from the water cooling plate 320 in the opposite direction of the third direction Z via the pressing surface 331a. In other words, the position regulating portion 312 is a part that protrudes or extends outward from the power supply device 310, and is positioned to receive the downward pressure from the connecting arm 331 and fix the power supply device 310 to the water cooling plate 320.

[0037] Refer to Figure 6, a perspective view of the through-hole 322 of the water-cooled plate 320 in Figure 4, where it is connected to the vacuum conduit 323. As shown in Figures 5 and 6, in this embodiment, the water-cooled plate 320 includes the through-hole 322 and the vacuum conduit 323 connected to the through-hole 322, the through-hole 322 connecting one side of the water-cooled plate 320 where the power supply device 310 is provided to the other side opposite to the one side. In this embodiment, when the handle 330 is in the open position, the connecting arm 331 no longer presses against the position regulating part 312. When an operator wants to separate the power supply device 310 from the water-cooled plate 320, gas can be injected into the through-hole 322 via the vacuum conduit 323, allowing the gas to enter the gap between the power supply device 310 and the water-cooled plate 320, thereby separating the power supply device 310 from the water-cooled plate 320. Conversely, when an operator attempts to fix the power supply unit 310 to the water cooling plate 320, the gas between the power supply unit 310 and the water cooling plate 320 can be discharged via the vacuum conduit 323, creating a near-vacuum state between the two and allowing for tighter contact.

[0038] Please refer to Figures 7 and 8. Figure 7 is a perspective view showing a power supply module 40 according to another embodiment of the present invention. Figure 8 is a localized enlarged view showing the power supply module 40 from a different viewpoint, by enlarging the area marked by the dashed circle A in Figure 7. As shown in Figures 7 and 8, in this embodiment, the power supply module 40 is mounted on a server rack (not shown) and comprises a first water-cooled plate 420, a power supply device 410 provided on the first water-cooled plate 420, and a second water-cooled plate 430 provided on the power supply device 410. The power supply module 40 further comprises a first handle 440 connected to the power supply device 410 and a second handle 450 connected to the second water-cooled plate 430. Specifically, the first handle 440 includes two first connecting arms 441 connected to opposing sides of the power supply device 410, and a first gripping portion 442 connecting the two first connecting arms 441. The second handle 450 includes two second connecting arms 451 connected to opposing sides of the second water-cooled plate 430, and a second gripping portion 452 connecting the two second connecting arms 451. In this embodiment, the power supply module 40 further comprises an outer frame 460 that can be mounted on a server rack, and an operator can grasp the first handle 440 of the power supply unit 410 and the second handle 450 of the second water-cooled plate 430, and the power supply unit 410 and the second water-cooled plate 430 can be attached to and detached from the outer frame 460 by modularization.

[0039] Please refer to Figure 9, a perspective view showing the state after the second water-cooling plate 430 of the power supply module 40 in Figure 7 has been detached from the outer frame 460. As shown in Figure 9, in this embodiment, when an operator attempts to separate the power supply 410 from the first water-cooling plate 420, it is first necessary to remove the second water-cooling plate 430 from the outer frame 460. Specifically, the second water-cooling plate 430 presses against the outer frame 460 via the pressing surface 451a of the second connecting arm 451 of the second handle 450, thereby separating the second water-cooling plate 430 from the power supply 410. In this embodiment, there is one first water-cooling plate 420 and two second water-cooling plates 430 in the outer frame 460, and the operator can remove the corresponding second water-cooling plate 430 depending on the location of the power supply 410 they are trying to remove, but the present invention is not limited thereto. In some embodiments, the second water cooling plate 430 may be a single, integrated design, or it may be more than two in number.

[0040] As shown in Figures 7 and 9, in this embodiment, the power supply device 410 presses the outer frame 460 via the pressing surface 441a of the first connecting arm 441 of the first handle 440, thereby separating the power supply device 410 from the first water cooling plate 420. After the second water cooling plate 430 is removed from above the power supply device 410, the power supply device 410 in this case cannot be removed directly from above because it is restricted by the outer frame 460. Therefore, the worker can first push the first gripping part 442 to separate the power supply device 410 from the first water cooling plate 420, and then pull out the power supply device 410 along the second direction Y.

[0041] Please refer to Figures 10 and 11. Figure 10 is a perspective view showing a power supply module 50 according to another embodiment of the present invention. Figure 11 is a close-up view showing the power supply module 50 in the area marked by the dashed circle B in Figure 10. As shown in Figures 10 and 11, in this embodiment, the power supply module 50 includes a first frame 540 and a second frame 550. The first frame 540 suitably supports the first water-cooled plate 420, and the second frame 550 suitably supports the second water-cooled plate 530. Specifically, the second frame 550 is mounted above the first frame 540, and the power supply device 410 is provided between the first water-cooled plate 420 and the second water-cooled plate 530. In this embodiment, the second frame 550 is provided with an engaging member 560, which is detachably fixed to the second frame 550 so as to suitably fix the second water cooling plate 530 and bring the second water cooling plate 530 into close contact with the power supply device 410.

[0042] As shown in Figures 10 and 11, in this embodiment, the engaging member 560 is similar to a T-shaped latch structure and can engage with the latch hole 531 in the second water cooling plate 530 and the lock hole 550a in the second frame 550. In this embodiment, the engaging member 560 includes an engaging portion 561, a connecting portion 562 and a protruding portion 563, the connecting portion 562 connects the engaging portion 561 and the protruding portion 563, and the engaging portion 561 is inserted into the latch hole 531 as the axis from which the connecting portion 562 rotates. When attempting to fix the second water-cooled plate 530 to the second frame 550, the worker moves the connecting portion 562 into the locking hole 550a. Because the volume of the protruding portion 563 is larger than the size of the hole in the locking hole 550a, the protruding portion 563 is blocked by the second frame 550, restricting the movement of the second water-cooled plate 530 in the third direction Z, thereby enhancing the fixing effect that brings the second water-cooled plate 530 into close contact with the power supply device 410. In this embodiment, the engaging members 560 may fix each of the four corners of the second water-cooled plate 530 so that an even force is applied to the second water-cooled plate 530, but the present invention is not limited thereto. In some embodiments, the engaging members 560 may fix at least one of the four corners of the second water-cooled plate 530, or may be provided on all four sides of the second water-cooled plate 530 so as to engage with the locking hole 550a in the second frame 550.

[0043] As shown in Figures 10 and 11, in this embodiment, the second frame 550 is provided with at least one leaf spring 570, and the leaf spring 570 is located between the second water-cooled plate 530 and the second frame 550. When the engaging member 560 engages the second water-cooled plate 530 and the second frame 550 (for example, the state shown in Figure 11), the leaf spring 570 is pressed by the second water-cooled plate 530 and stores elastic energy. Furthermore, when an operator attempts to separate the second water-cooled plate 530 from the second frame 550, the operator can loosen the engaging member 560 and pull out the connecting portion 562 of the engaging member 560 from the lock hole 550a, thereby detaching it. This prevents the protruding portion 563 from being blocked by the second frame 550, releasing the elastic energy stored in the leaf spring 570. At this time, the second water-cooled plate 530 is pressed by the leaf spring 570 and moves away from the second frame 550 in the third direction Z, allowing the operator to easily insert and remove the power supply device 410.

[0044] Please refer to Figures 12, 13, and 14. Figure 12 is a perspective view showing a power supply module 60 according to another embodiment of the present invention. Figure 13 is an exploded view showing the power supply module 60 of Figure 12. Figure 14 is a localized enlargement view showing the power supply module 60 enlarged in the area marked by the dashed circle C in Figure 13. As shown in Figures 12 to 14, in this embodiment, the second water cooling plate 630 of the power supply module 60 includes a latch hole 631, and the second handle 640 of the second water cooling plate 630 is inserted into and fixed in the latch hole 631. Specifically, the second handle 640 has an engaging portion 641 and a gripping portion 642, and the engaging portion 641 of the second handle 640 is inserted into the latch hole 631 as the axis of the second handle 640. In other words, the operator can raise and lower the second handle 640 by holding the gripping portion 642 with their hand. In this embodiment, the power supply module 60 further includes a stopper piece 680 that can restrict the rotation of the second handle 640. Specifically, when the gripping portion 642 of the second handle 640 rotates to the lower edge of the stopper piece 680, the gripping portion 642 can be fitted into the stopper groove 681 of the stopper piece 680. At this time, the second handle 640 moves in conjunction with the second water cooling plate 630 to bring it into close contact with the power supply device 610, thereby increasing the heat dissipation effect of the power supply module 60.

[0045] As shown in Figures 12 to 14, in this embodiment, the power supply module 60 further comprises a roller 670. When an operator pulls out the power supply 610 or inserts it into the outer frame 660 along the second direction Y or the opposite direction of the second direction Y, the roller 670 contacts one side of the power supply 610 facing the first water cooling plate 420 by rolling in place, thereby making it easier to insert and remove the power supply 610. Specifically, fitting grooves 661 are provided on both opposing sides of the outer frame 660, and fitting portions 671 that fit into the fitting grooves 661 are provided on both opposing sides of the roller 670. The roller 670 can be fixed to the bottom side of the outer frame 660 near the stopper piece 680 via the fitting grooves 661. In this embodiment, the roller 670 is adjacent to the first water cooling plate 420 and rotates with the fitting portion 671 as its axis.

[0046] Please refer to Figure 15, a localized enlargement view showing the power supply module 60, enlarged in the area marked by the dashed circle D in Figure 13. As shown in Figure 15, and referring in conjunction with Figures 12 and 13, in this embodiment the power supply module 60 further comprises a rail 662. The rail 662 connects opposing sides of the outer frame 660 and is provided in a position close to the second water-cooled plate 630 of the outer frame 660. Specifically, a screw 632 is provided on the side of the second water-cooled plate 630 closer to the outer frame 660, and the screw 632 can pass through the rail 662 to fix the second water-cooled plate 630 to the outer frame 660. In this embodiment, the rail 662 has an upper end 662a closer to the second frame 650 and a lower end 662b further away from the second frame 650. When the second handle 640 of the second water cooling plate 630 is pressed down, the screws 632 of the second water cooling plate 630 move from the upper end 662a to the lower end 662b of the rail 662 and are fixed within the lower end 662b. This allows the second water cooling plate 630 to be brought into close contact with the power supply device 610, thereby enhancing the fixing effect on the sides of the second water cooling plate 630.

[0047] Furthermore, as shown in Figure 15, and referring in conjunction with Figures 10 and 11, in this embodiment the power supply module 60 further comprises a leaf spring 570. The leaf spring 570 was described in detail in the embodiment of the power supply module 50 described above, and will not be described again here. In this embodiment the leaf spring 570 is provided on the second frame 650 and is located between the second frame 650 and the second water cooling plate 630.

[0048] Please refer to Figure 16, which shows a rear perspective view of the power supply unit 610 positioned on the first water cooling plate 420 in the power supply unit module 60 in Figure 13. As shown in Figure 16, and referring to it in conjunction with Figure 13, in this embodiment, a roller 611 is provided on the rear side of the power supply unit 610 (i.e., the side away from the first handle 620). Specifically, the roller 611 is provided on the lower edge of the power supply unit 610 that contacts the first water cooling plate 420, and the roller 611 makes it easier to slide the power supply unit 610 on the first water cooling plate 420, enabling insertion and removal of the power supply unit 610. In this embodiment, there are two rollers 611, but the present invention is not limited to this.

[0049] Please refer to Figure 17, a perspective view showing a power supply module 70 according to another embodiment of the present invention. As shown in Figure 17, in this embodiment, the power supply module 70 is mountable on a server rack (not shown). The power supply module 70 comprises a first water-cooled plate 420 and a power supply unit 710, the power supply unit 710 being provided on the first water-cooled plate 420. In this embodiment, the power supply module 70 further comprises a second water-cooled plate 730, the second water-cooled plate 730 being provided correspondingly on the power supply unit 710. That is, the power supply unit 710 is located between the first water-cooled plate 420 and the second water-cooled plate 730. In this embodiment, the power supply module 70 further includes an outer frame 760 that can be mounted on a server rack. Specifically, the power supply unit 710, the first water-cooled plate 420, and the second water-cooled plate 730 are modularized and attached to the outer frame 760, and the outer frame 760 can be installed in a server rack. In this embodiment, the number of second water-cooled plates 730 corresponds to the number of power supply units 710, but the present invention is not limited thereto. In some embodiments, a single second water-cooled plate 730 may be provided on two or more power supply units 710, or multiple second water-cooled plates 730 may all be provided on a single power supply unit 710.

[0050] Please refer to Figure 18, which is an exploded view showing the power supply unit 710 of the power supply module 70 shown in Figure 17. As shown in Figures 17 and 18, in this embodiment, the power supply unit 710 includes a case 711, the case 711 having a bottom plate 711a, a first side plate 711b, and a second side plate 711c, the first side plate 711b and the second side plate 711c being located on opposite sides of the bottom plate 711a. Specifically, the first side plate 711b is in contact with the first water cooling plate 420, and the second water cooling plate 730 is in contact with the corresponding second side plate 711c of the power supply unit 710. In other words, the power supply unit 710 is in contact with the first water cooling plate 420 on the side where the first side plate 711b is located, and with the second water cooling plate 730 on the side where the second side plate 711c is located. In this embodiment, the power supply device 710 further includes a main circuit board c1 and at least one sub-circuit board c2, the main circuit board c1 being fixed to a bottom plate 711a, and the sub-circuit board c2 being positioned on the side of the main circuit board c1 and in close contact with the first side plate 711b, but the present invention is not limited thereto. In some embodiments, the sub-circuit board c2 may be in close contact with the second side plate 711c, or in close contact with both the first side plate 711b and the second side plate 711c.

[0051] Please refer to Figures 19 and 20. Figure 19 is a rear perspective view showing the power supply module 70 shown in Figure 17 with the outer frames 760 on both sides omitted. Figure 20 is a plan side view showing the power supply module 70 in Figure 19. As shown in Figures 19 and 20, and in conjunction with Figures 17 and 18, in this embodiment the second water cooling plate 730 has a front end 730a and a rear end 730b. Specifically the second water cooling plate 730 includes a second handle 740 for gripping and pressing the power supply unit 710, and the second handle 740 is located at the front end 730a of the second water cooling plate 730. In this embodiment the front end 730a of the second water cooling plate 730 is detachably fixed to the corresponding power supply unit 710 via a locking mechanism 780. Specifically, the power supply device 710 includes a first handle 720, and the locking mechanism 780 sequentially passes through the second handle 740 of the second water-cooled plate 730 and locks onto the first handle 720, allowing the second water-cooled plate 730 to be brought into close contact with the power supply device 710. In another embodiment, the locking mechanism 780 is removably fixed to the outer frame 760 and sequentially passes through the second handle 740 of the second water-cooled plate 730 and locks onto the outer frame 760. In other words, by loosening the locking mechanism 780, the operator can release the lock between the front end 730a of the second water-cooled plate 730 and the power supply device 710 or the outer frame 760.

[0052] Furthermore, as shown in Figures 19 and 20, and also referring to Figures 17 and 18, in this embodiment, the end 730b of the second water-cooled plate 730 is pivotally attached to the outer frame 760 via a pivot mechanism 790. Specifically, the pivot mechanism 790 includes a pivot 791 whose axial direction R is parallel to the outer surface s of the second side plate 711c. In other words, the second water-cooled plate 730 is rotatable about the pivot 791 of the pivot mechanism 790, and even after the front end 730a of the second water-cooled plate 730 is unlocked, its end 730b remains pivotally attached to the outer frame 760 via the pivot mechanism 790, and the opening and closing angle of the second water-cooled plate 730 can be adjusted about the pivot 791, so that the operator can easily insert and remove the power supply device 710. In this embodiment, the power supply device module 70 further includes a leaf spring 770 fixed to the first water-cooled plate 420. Specifically, the leaf spring 770 is located on the side where the pivot mechanism 790 is situated, and strongly presses against the side of the first side plate 711b of the power supply device 710 that is away from the first water cooling plate 420, pushing the first side plate 711b downwards and bringing it into closer contact with the first water cooling plate 420, thereby achieving a better heat dissipation effect.

[0053] As will be clear from the detailed description of the specific embodiments of this invention, in the power supply device module of this invention, a protrusion provided on the connecting arm allows the water cooling plate to be pressed simultaneously when the handle is pushed down or pulled up, thereby separating the power supply device and the water cooling plate. The hook portion of the handle and the clamp member on the water cooling plate allow the power supply device to be fixed to the water cooling plate and to be in close contact with the water cooling plate. The position regulating portion of the power supply device allows the position regulating portion to be pressed simultaneously when the handle is pushed down, thereby completing the fixing of the power supply device. The engaging member and the leaf spring provided on the frame allow the water cooling plate to be brought into close contact with the power supply device, and after the lock of the engaging member is released, the water cooling plate can be separated from the power supply device and the frame. The locking mechanism and the pivot mechanism allow the front end of the water cooling plate to be fixed to the power supply device or the outer frame, the end of the water cooling plate to be pivotally attached to the outer frame, and the pivot of the pivot mechanism to be rotated around the axis.

[0054] Although the present invention has been disclosed in the embodiments described above, these embodiments are not intended to limit the present invention, and any person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and the scope of protection of the present invention should be based on the claims for registration of the utility model that are attached thereto.
