TECHNICAL FIELD

[0001] The utility model relates to the cooling technical field of server, more particularly to a spray type liquid cooling server. BACKGROUND

[0002] In actual server modification, the heat generating electronic devices in the server are usually connected with heat transfer devices to promote heat dissipation, due to the diversified characteristics of the structure and source of the electronic devices, which leads to the differences in the connection mode, appearance, etc. between the heat transfer devices and the electronic devices. When the spray liquid cooling system is used to cool the server, the spray mechanism usually sprays the cooling liquid from top to bottom towards the heat generating devices, and the structure of some electronic devices and heat transfer devices is difficult to contact the spray cooling liquid, and if the full immersion liquid cooling method is used, it will cause the waste of cooling liquid, and also increase the cost of server modification.

[0005] The box body is provided with an upward box body opening and a liquid outlet;

[0006] The spray plate covers the box body opening, and the surface of the spray plate towards the inside of the box body is provided with a plurality of spray units;

[0008] In the scheme, the spray plate sprays the low-temperature cooling liquid towards the opening of the liquid guide groove through the spraying unit, the cooling liquid gathered in the liquid guide groove is introduced into the inside of the shell through the first liquid inlet hole, the cooling liquid immerses the first heat transfer member and / or the first heat generating member in the inside of the shell, and the first heat generating member is directly or indirectly immersed for liquid immersion cooling, in the process, the cooling liquid heated after absorbing heat flows out of the shell through the first liquid outlet hole, and the low-temperature cooling liquid sprayed outside can continuously supplement the liquid into the shell through the liquid guide groove, so as to efficiently cool the first heat generating member. In addition, the other heat generating member units in the inside of the box are sprayed for liquid spray cooling by the cooling liquid sprayed by the spray plate, so that different heat generating member units in the inside of the server can be respectively sprayed for liquid spray cooling or immersed for liquid immersion cooling without changing the structure of the spray plate, the heat dissipation requirements of different heat generating members can be met, and the amount of cooling liquid can be significantly reduced relative to the complete immersion liquid cooling, so that the overall load of the server is prevented from being too large to cause harsh requirements on the bearing structure.

[0009] In some embodiments, the first liquid inlet hole is located higher than the first liquid outlet hole.

[0010] The scheme helps the cooling liquid to output the shell by means of its own gravity, and promotes the circulation and heat exchange between the cooling liquid in the inside of the shell and the externally sprayed cooling liquid.

[0011] In some embodiments, the first liquid inlet hole has a larger hole diameter than the first liquid outlet hole.

[0012] In the scheme, the cooling liquid gathered in the liquid guide groove flows into the shell through the first liquid inlet hole by means of its own gravity, and flows out of the shell through the first liquid outlet hole by means of its own gravity, and by simply adjusting the size of the hole diameter, the cooling liquid inlet flow rate of the shell can be made to be greater than the outlet flow rate, so that the cooling liquid can immerse the first heat transfer member and / or the first heat generating member in the inside of the shell.

[0013] In some embodiments, the shell is further provided with a connecting piece for fixedly connecting the box.

[0014] In some embodiments, the inside space of the liquid guide groove is a cone with a wide upper part and a narrow lower part.

[0015] The scheme can reduce the inside space of the liquid guide groove and improve the speed of gathering the cooling liquid in the liquid guide groove under the condition that the opening area of the groove is unchanged, so as to accelerate the rate of delivering the cooling liquid into the inside of the shell.

[0016] In some embodiments, the lowest part of the first liquid inlet hole is lower than the upper end surface of the liquid guide groove.

[0017] The scheme can ensure that the cooling liquid gathered in the liquid guide groove is input into the inside of the shell under the action of its own gravity.

[0018] In some embodiments, the first heat transfer member comprises a plurality of first fins in thermal conductive connection with the first heat generating member, each of the first fins has a length in the horizontal direction, and the plurality of first fins are arranged in gaps in the vertical direction.

[0019] The first liquid inlet hole and the first liquid outlet hole are respectively located on both sides of the length direction of the plurality of first fins.

[0020] This scheme can reduce the space occupied by the first fins in the horizontal direction, thereby reducing the size of the first heat generating device unit in the horizontal direction. In addition, the gaps formed between adjacent first fins can act as a cooling liquid flow channel. After the cooling liquid collected by the liquid guide groove is input into the housing through the first liquid inlet hole, the cooling liquid can fully absorb the heat of the first fins through the cooling liquid flow channel and flow out of the housing through the first liquid outlet hole, thereby achieving immersion liquid cooling of the first heat generating member and significantly improving the heat dissipation rate.

After the heat exchange, the cooling liquid with increased temperature flows out of the frame body upper opening or the gap between the lower end surface of the frame body and the upper surface of the heat conductive bottom plate. The spray unit sprays low-temperature cooling liquid to continuously supplement the internal space of the frame body, thereby forming a cooling liquid circulation in the frame body. In this way, the heat exchange level between the spray cooling liquid and the second heat transfer member can be significantly improved.

[0029] In some embodiments, the side part of the frame body is provided with a second liquid outlet hole for discharging the cooling liquid.

[0030] In some embodiments, the lower end surface of the frame body and the upper surface of the heat-conducting lower bottom plate are left with a liquid outlet gap for the cooling liquid to seep out.

[0032] The plurality of second fins are gap-provided along the thickness direction of the second fins, and the cooling liquid can pass between adjacent second fins.

[0033] In the scheme, the cooling liquid in the frame body can be in full contact with the second fins, and the spraying of the cooling liquid can be directly sprayed on the upper heat-conducting plate or the upper heat-conducting plate is immersed in the cooling liquid, thereby significantly improving the cooling rate of the second heat transfer member.

[0035] In the scheme, the liquid storage tray can buffer the cooling liquid of the box body, and by adjusting the liquid level in the liquid storage tray, the amount of cooling liquid in the box body can be controlled, which is helpful for adjusting the appropriate liquid cooling level according to the actual heat generating condition.

[0036] In some embodiments, the side part of the liquid storage tray is provided with an overflow gap.

[0037] In the scheme, the highest liquid level of the liquid storage tray is automatically adjusted through the overflow gap, which is convenient for automatic adjustment of the safety liquid level.

[0044] In addition, the other heat generating component units inside the box are sprayed by the cooling liquid sprayed by the spraying plate, so that the spraying liquid cooling or immersion liquid cooling of different heat generating component units inside the server can be realized without changing the structure of the spraying plate, the heat dissipation requirements of different heat generating components can be met, and the amount of cooling liquid can be significantly reduced relative to the complete immersion liquid cooling.

DETAILED DESCRIPTION

[0055] The drawings of the utility model are only used for example description, and cannot be understood as the limitation of the utility model. In order to better illustrate the following embodiments, some components of the drawings can be omitted, enlarged or reduced, and the size of the actual product is not represented; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings can be omitted.

[0056] Embodiment 1

[0057] As shown in Figures 1-5 , the embodiment provides a spray type liquid cooling server, which comprises:

[0058] The box 100 is provided with the upward box opening 110 and the liquid outlet 120;

[0059] The spray plate 200 covers the box opening 110, and the surface of the spray plate 200 towards the inside of the box is provided with a plurality of spray units, and in specific implementation, the spray units comprise the first spray unit 210 and the second spray unit 220, and the spray unit can be realized in the mode of a plurality of densely arranged spray holes;

[0060] The first heat generating unit 300 is arranged in the cabinet 100, and the first heat generating unit 300 comprises a shell 310, a first heat generating element 320, a first heat transfer element 330 and a liquid guide groove 340. The shell 310 is provided with a first liquid inlet hole 311 and a first liquid outlet hole 312. The first heat transfer element 330 and the first heat generating element 320 are both arranged in the shell 310 and are in thermal conduction connection. The liquid guide groove 340 is arranged on the outer surface of the shell 310, and the inside of the liquid guide groove 340 is in communication with the first liquid inlet hole 311. The liquid guide groove 340 is provided with a groove opening upward, and the first spraying unit 210 sprays the cooling liquid toward the groove opening. It should be noted that the shell 310 is made of a material with good thermal conductivity. It should be noted that in some embodiments, the server comprises a plurality of first heat generating units 300. At this time, referring to Figure 2 , a plurality of first spraying units 210 need to be arranged to spray the cooling liquid to the liquid guide groove 340 of each first heat generating unit 300.

[0061] In specific implementation, in order to facilitate assembly, the shell 310 comprises a base plate 313 and a cover 314. The first heat generating element 320 can be a GPU card in a flat plate shape. The GPU card is arranged on the base plate 313, the first heat transfer element 330 is in thermal conduction connection with the surface of the GPU card, and the cover 314 covers the base plate 313 to jointly form the hollow shell 310. The first liquid inlet hole 311 is arranged on the cover 314, and the liquid guide groove 340 is detachably arranged on the surface of the cover 314 or the base plate 313 near the liquid inlet hole. In order to ensure internal heat dissipation, the conventional GPU card shell 310 is provided with a hollow structure 315 penetrating the inside. Specifically, referring to Figure 5 , the hollow structure 315 is arranged on the cover 314. In addition, if the hollow structure 315 is used as the liquid outlet channel of the cooling liquid, the liquid outlet flow is too large, and it is difficult for the cooling liquid to fill the internal space of the shell 310. Therefore, the present embodiment is further provided with a baffle 350. The baffle 350 blocks the hollow structure 315, and the baffle 350 is provided with a through hole with a small hole diameter as the liquid outlet hole of the shell 310. The periphery of the baffle 350 is sealed to make the cooling liquid in the shell 310 flow out only through the liquid outlet hole, so that the liquid outlet flow is small, and the cooling liquid in the shell 310 can be immersed in the first heat transfer element 330 and / or the first heat generating element 320 by spraying the cooling liquid.

[0062] In actual use, the spray plate 200 sprays the low-temperature cooling liquid toward the opening of the liquid guide groove 340 through the first spray unit 210. The cooling liquid gathered in the liquid guide groove 340 is introduced into the shell 310 through the first liquid inlet hole 311, and the cooling liquid immerses the first heat transfer member 330 and / or the first heat generating member 320 in the shell 310, directly or indirectly immersing the first heat generating member 320 for liquid immersion cooling. In this process, the cooling liquid heated after absorbing heat flows out of the shell 310 through the first liquid outlet hole 312, and the low-temperature cooling liquid sprayed externally can continuously supplement the liquid into the shell 310 through the liquid guide groove 340, thereby efficiently cooling the first heat generating member. In addition, other heat generating member units in the box body 100 are sprayed by the cooling liquid sprayed by the spray plate 200 for spray liquid cooling. In this way, different heat generating member units in the server can be respectively sprayed and immersed for liquid cooling without changing the structure of the spray plate 200, which can meet the heat dissipation requirements of different heat generating members, and can significantly reduce the amount of cooling liquid required for complete immersion liquid cooling, prevent the overall load of the server from being too large, and cause harsh requirements on the load-bearing structure.

[0063] Reference Figure 5 The position of the first liquid inlet hole 311 is higher than that of the first liquid outlet hole 312. In actual implementation, after the spray cooling liquid is gathered in the liquid guide groove 340, the cooling liquid can basically only rely on its own gravity to circulate in the shell 310. Therefore, by setting the position of the first liquid inlet hole 311 to be higher than that of the first liquid outlet hole 312, a cooling liquid channel for the cooling liquid to flow from high to low can be constructed, and the circulation and heat exchange between the cooling liquid in the shell 310 and the spray cooling liquid can be promoted. It is easy to understand that as long as the liquid inlet flow rate of the first liquid inlet hole 311 is greater than the liquid outlet flow rate of the first liquid outlet hole 312, the cooling liquid can completely immerse the first heat transfer member 330, and the heat dissipation efficiency of the first heat transfer member 330 can be improved.

[0064] Reference Figure 5 In order to achieve immersion liquid cooling for the first heat generating member 320, the diameter of the first liquid inlet hole 311 is greater than that of the first liquid outlet hole 312. It is easy to understand that the cooling liquid gathered in the liquid guide groove 340 needs to flow into the shell 310 from the first liquid inlet hole 311 by its own gravity, and then flow out of the shell 310 from the first liquid outlet hole 312 by its own gravity. By simply adjusting the size of the hole diameter, the liquid inlet flow rate of the cooling liquid in the shell 310 can be greater than the liquid outlet flow rate, so that the cooling liquid can immerse the first heat transfer member 330 and / or the first heat generating member 320 in the shell 310.

[0065] Reference Figures 4-5, the inner space of the liquid guide groove 340 is a taper with the upper part wider and the lower part narrower, so that the inner space of the liquid guide groove 340 is reduced and the speed of the cooling liquid gathered in the liquid guide groove 340 is increased, thereby increasing the rate of the cooling liquid transported into the housing 310.

[0066] Referring to Figure 4 , in order to ensure that the cooling liquid can be smoothly guided into the housing 310, the lowest part of the first liquid inlet hole 311 is lower than the upper end surface of the liquid guide groove 340, so that the cooling liquid gathered in the liquid guide groove 340 can be input into the housing 310 under the action of its own gravity.

[0067] As shown in Figure 5 , the first heat transfer member 330 includes a plurality of first fins 331 in heat transfer connection with the first heat generating member 320, the first fins 331 each have a length in the horizontal direction, and the plurality of first fins 331 are arranged in gaps in the vertical direction; the first liquid inlet hole 311 and the first liquid outlet hole 312 are respectively arranged on the two sides of the length direction of the first fin 331.

[0068] In actual application, the arrangement of the first fin 331 can reduce the space occupied by it in the horizontal direction, thereby reducing the size of the first heat generating device unit 300 in the horizontal direction, in addition, the gap formed between adjacent first fins 331 can serve as a cooling liquid flow channel, after the cooling liquid collected by the liquid guide groove 340 is input into the housing 310 through the first liquid inlet hole 311, it can fully absorb the heat of the first fin 331 through the cooling liquid flow channel, and then flow out of the housing 310 through the first liquid outlet hole 312, thereby realizing immersion liquid cooling of the first heat generating member 320.

[0069] Referring to Figures 3-5 , the housing 310 further comprises a connecting member 360 for fixing the inner surface of the box 100. In specific implementation, the connecting member 360 is a handle strip fixed on the housing 310, referring to Figure 3 、 5 , the handle strip can be clamped on the baffle 350 and the cover member 314, at this time, the middle part of the handle strip has a through hole 361 for connecting the first liquid outlet hole 312 on the baffle 350 and the hollow structure 315 of the cover, and the lower part of the handle strip is provided with an embedding opening 362, by embedding the embedding opening 362 into the convex part matched with the bottom surface of the box 100, the first heat generating device unit 300 can be stably arranged in the box 100.

[0070] As shown in Figure 1 、 2As shown in Figures 6 and 7, a second heating element unit 400 is also provided inside the housing 100. The second heating element unit 400 includes a second heating element, a second heat transfer element, and a frame 410 that runs vertically through the housing. The second heating element is located on the inner bottom surface of the housing 100. The second heat transfer element includes a heat dissipation part 430 and a heat-conducting lower base plate 420 that are thermally connected. The heat dissipation part 430 is located on the upper surface of the heat-conducting lower base plate 420, and the lower surface of the heat-conducting lower base plate 420 is thermally connected to the upper surface of the second heating element. The lower end face of the frame 410 abuts against the upper surface of the heat-conducting lower base plate 420. The heat dissipation part 430 is provided in the internal space of the frame 410, and there is a gap between the inner surface of the frame 410 and the heat dissipation part 430. The second spray unit 220 sprays coolant in a spaced manner.

[0071] In specific implementations, the second heating element is a flat CPU, and the frame 410 is made of a material with good thermal conductivity. It should be noted that in some embodiments, the server includes multiple second heating element units 400; in this case, refer to... Figure 2 Multiple second spray units 220 need to be set up to spray coolant onto the openings 414 on the frame of each second heating device unit 400.

[0072] In practical use, the frame 410 is vertically open to form an upper opening 414 and a lower opening 415 on its upper and lower surfaces, respectively. The lower opening 415 abuts against the heat-conducting lower base plate 420. The coolant sprayed by the second spray unit 220 is introduced into the frame 410 through the upper opening 414. After the coolant collects in the frame 410, it partially or completely submerges the second heat transfer element. At the same time, the coolant can also directly contact the upper surface of the heat-conducting lower base plate 420 for liquid cooling heat exchange, thereby improving the heat exchange level between the coolant and the second heat transfer element. After heat exchange, the coolant with increased temperature overflows from the upper opening 414 or seeps out from the gap between the lower end of the frame and the upper surface of the heat-conducting lower base plate 420. Meanwhile, the low-temperature coolant sprayed by the second spray unit 220 can continuously replenish the internal space of the frame 410, thereby forming a coolant circulation.

[0073] refer to Figure 6 , 7 To reduce the internal space of the frame, the orthographic cross-section of the heat dissipation part 430 is cross-shaped, and the orthographic cross-section of the internal space of the frame 410 is rectangular. At this time, the inner surface of the frame 410 can be tightly fitted against the outer surface of the heat dissipation part 430, and the structural strength of the frame 410 is improved by the support of the heat dissipation part 430. Furthermore, several gaps are formed around the opening 414 on the frame and the heat dissipation part 430, and the coolant sprayed by the second spray unit 220 can be introduced into the interior of the frame 410 through the gaps. Thus, based on the relatively small internal space of the frame 410, the coolant can be fully immersed in the heat dissipation part 430.

[0074] refer to Figure 6 , 7 The heat dissipation part 430 is provided with an outer extension member 431 extending outward relative to the orthographic projection section of the heat dissipation part 430, and the lower end face of the frame 410 is provided with an inner extension member 416 extending inward. The inner extension member 416 and the outer extension member 431 are tightly fitted together.

[0075] In use, since the lower part of the frame 410 is close to the heat dissipation part 430, the structural strength of the frame 410 can be improved by the support of the heat dissipation part 430. Furthermore, in this embodiment, the internal space of the frame 410 only needs to be slightly larger than the heat dissipation part 430, promoting miniaturization, reducing the amount of coolant required, and effectively reducing the overall load on the second heat-generating device unit 400. (Continue to refer to...) Figure 7 The outer extension member 431 specifically includes a connector that extends outward from the orthographic projection section relative to the heat dissipation part 430. More specifically, the connector is a bolt that passes through the heat-conducting lower base plate. The second heat transfer element is fixed to the outer casing 100 or the second heating element by the bolt. The inner extension member 416 specifically includes an arc-shaped part that extends inward from the lower opening of the frame 200 and a structure connected thereto. More specifically, the arc-shaped part is used to avoid the bolt, so that the inner extension member 416 and the outer extension member 431 can be tightly fitted together.

[0076] like Figures 7-8 As shown, for ease of installation and removal, the frame 410 includes a detachably connected first shell 411 and a second shell 412. The first shell 411 and the second shell 412 cooperate to jointly enclose the heat dissipation section 430. Continuing to refer to the present invention, the first shell 411 and / or the second shell 412 are provided with inner extension members 416. Thus, when both the first shell 411 and the second shell 412 are provided with inner extension members 416, it is convenient for the inner extension members 416 of the first shell 411 and the inner extension members 416 of the second shell 412 to abut against the corresponding outer extension members 431 on the heat dissipation section 430, reducing installation difficulty and preventing the gap between the lower end face of the frame 410 and the heat-conducting lower base plate 420 from becoming too large, which helps the coolant to fill the interior of the frame 410. In a preferred embodiment, the connection between the first housing 411 and the second housing 412 is an interlocking fit and reinforced with a threaded connection, thereby improving the sealing of the connection and reducing coolant leakage.

[0077] like Figure 6 , 7 As shown, the side of the frame 410 is provided with a second outlet hole 413 for coolant discharge. In specific implementation, there are several second outlet holes 413. Preferably, the several second outlet holes 413 are respectively set at different heights to ensure that the coolant can be discharged from the frame 410 under its own gravity.

[0078] In some embodiments, referring to Figures 6 and 7, a coolant outlet gap is provided between the lower end face of the frame 410 and the upper surface of the heat-conducting lower base plate 420 for coolant to seep out. In this case, the second outlet hole 413 is not required. In specific implementation, the lower end face of the frame 410 abuts against the upper surface of the heat-conducting lower base plate 420, but the contact surface between the two is not sealed. Thus, there is a small coolant outlet gap between the lower end face of the frame 410 and the upper surface of the heat-conducting lower base plate 420. Under its own gravity, the coolant can seep out of the frame 410 through the outlet gap. Since the coolant seepage flow rate is small, it is easy to achieve a flow rate of sprayed coolant introduced into the frame 410 that is greater than the discharge flow rate. As a result, the coolant can fill the internal space of the frame 410, completely or partially immersing the heat dissipation part 430.

[0079] like Figures 6-7 As shown, the second heat transfer element includes an upper heat-conducting plate 432 and a plurality of second fins 433. The upper ends of the plurality of second fins 433 are all thermally connected to the lower surface of the upper heat-conducting plate 432, and the lower ends of the plurality of second fins 433 are all thermally connected to the lower heat-conducting base plate 420. The plurality of second fins 433 are spaced apart along their own thickness direction, and coolant can pass between adjacent second fins 433.

[0080] Specifically, refer to Figure 1 , 7 Several second fins 433 are encapsulated within a heat-conducting frame. The second fins 433 are arranged horizontally with gaps on the upper surface of the heat-conducting lower base plate 420. The frame 410 surrounds the second fins 433, thus forming a channel connecting the front and rear sides of the frame 410. In practical applications, spray-type liquid cooling can be achieved by spraying coolant towards the upper heat-conducting plate 432 through the second spray unit 220 or by setting other spray units. At the same time, the coolant sprayed by the second spray unit 220 towards the opening 414 on the frame also gathers inside the frame 410, thereby immersing the second fins 433 and the upper surface of the heat-conducting lower base plate 420 with liquid cooling. In this way, the two liquid cooling methods work together to improve the cooling rate of the second heat-generating component.

[0081] refer to Figures 1-2 The liquid-cooled server also includes a liquid storage tray 500, with the enclosure 100 placed inside the liquid storage tray 500. The liquid outlet 120 is connected to the interior of the liquid storage tray 500. In practice, the liquid storage tray 500 can buffer the coolant in the enclosure 100, and by adjusting the liquid level in the liquid storage tray 500, the amount of coolant in the enclosure 100 can be controlled, which helps to adjust the appropriate liquid cooling level according to the actual operating conditions of the heat-generating components.

[0082] refer to Figure 9To facilitate adjustment of the coolant level in the liquid-cooled server, an overflow notch 510 is provided on the side of the coolant reservoir 500. Thus, when the coolant level in the reservoir 500 is higher than the overflow notch 510, the coolant is automatically discharged from the reservoir 500, thereby achieving automatic adjustment of the coolant level. In practice, multiple overflow notches 510 can be provided.

[0083] refer to Figure 9 The lower part of the liquid storage tray 500 is provided with a drain port 520. It is easy to understand that the liquid level in the liquid storage tray 500 can be easily adjusted through the drain port 520 to meet the actual heat dissipation needs of the server. In addition, the flow of coolant in the liquid storage tray 500 and the housing 100 can be enhanced through the drain port 520, thereby improving the heat exchange rate.

[0084] refer to Figure 9 The liquid storage tray 500 includes a tray body 530 and a front sealing plate 540 and a rear sealing plate 550, which are detachably connected to the front and rear ends of the tray body 530, respectively. This facilitates the insertion of the container 100 into the liquid storage tray 500, and allows for easy maintenance by removing the front sealing plate 540 or the rear sealing plate 550 from either direction. In practice, the front sealing plate 540 and the rear sealing plate 550 can be connected to the tray body using screws or other methods, as long as the joints are properly sealed to prevent leakage.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the claims of this utility model should be included within the protection scope of the claims of this utility model.
