Abstract
Description
Technical Field
[0001] This utility model belongs to the field of data center technology, and in particular relates to an immersion cooling box. Background Technology
[0002] In recent years, with the improvement of GPU computing speed and the continuous development of microelectronics technology, chip power consumption and heat generation have become increasingly large. The immersion cooling technology commonly used in current technology is mainly a type of immersion cooling, which means immersing electronic devices in an immersion cooling chamber. However, since the flow inside the immersion cooling chamber relies on the change in the cold and hot density of the coolant itself to form a flow, the local flow rate is relatively slow.
[0003] Meanwhile, when the GPU generates heat, the coolant vaporizes on its surface, creating a gas film that affects the flow of liquid and carries away the heat from the GPU.
[0004] Therefore, there is an urgent need to provide an immersion cooling enclosure to solve the problem of insufficient heat exchange efficiency caused by the formation of air film in existing two-phase liquid-cooled server enclosures.
[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content
[0006] This disclosure provides at least one immersion cooling enclosure, including: an enclosure body, the interior of which is provided with a plurality of GPU storage slots;
[0007] A cooling assembly, disposed within the housing, is used to introduce coolant into the housing; wherein
[0008] The cooling nozzles of the cooling component correspond to each GPU storage location, so that the coolant is sprayed onto the corresponding GPU storage location;
[0009] The top of the box body is provided with an exhaust pipe to discharge the steam formed after the coolant inside the box body evaporates.
[0010] In one alternative embodiment, the box body includes: a cover and a receiving groove;
[0011] The GPU storage location is disposed within the receiving slot; and
[0012] The depth of the receiving slot is greater than the height of the GPU.
[0013] In one alternative embodiment, the cooling assembly includes: an inlet pipe and a spray plate;
[0014] The inlet plate is installed on the top of the receiving tank; wherein
[0015] The inlet pipe is embedded in the bottom frame of the tank body, and the outlet of the inlet pipe is connected to the inlet of the spray plate; and
[0016] The cooling nozzles are located in the concave surface of the middle part of the spray plate.
[0017] In one optional embodiment, the spray plate includes: a plate body;
[0018] The plate body is provided with cooling channels, which are connected to the liquid inlet and the central concave surface to introduce coolant into the central concave surface.
[0019] In one optional implementation, the GPU storage bits are arranged in an N×M pattern; wherein
[0020] N represents N rows, and M represents M columns.
[0021] In one optional implementation, when N and / or M are even numbers, the number of storage bits in the GPU is an even number; and
[0022] The number of cooling nozzles is even, and each nozzle corresponds to a storage location in the GPU.
[0023] In one optional implementation, when N and M are odd numbers, the number of storage bits in the GPU is odd; and
[0024] The number of cooling nozzles is odd, and each nozzle corresponds to a storage location in the GPU.
[0025] In one optional embodiment, the housing also includes a CPU storage location and a power supply storage location.
[0026] In one alternative implementation, the CPU storage location is located on one side of the GPU storage location, and the power storage location is located on the other side of the GPU storage location.

[0028] The beneficial effects of this utility model are that the immersion cooling enclosure has several GPU storage slots set inside the enclosure to place the GPUs to be used. Coolant is injected into the enclosure through the set cooling components, so that multiple GPUs are immersed in the coolant to achieve heat dissipation. At the same time, the cooling nozzles of the cooling components correspond to the positions of each GPU storage port, so that the coolant can be directly sprayed onto the corresponding GPU surface, thereby breaking through the air film on the GPU surface, so that the GPU surface can fully contact the coolant. The steam formed after the coolant evaporates inside the enclosure is discharged through the vent pipe opened on the enclosure body, realizing a two-phase cooling cycle and improving heat exchange efficiency.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0042] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the figures, the thickness of parts may be exaggerated or reduced for the purpose of effectively depicting the technical content.
[0043] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0044] See Figure 1 This disclosure provides at least one immersion cooling enclosure, comprising: an enclosure body 1 having a plurality of GPU storage slots 110 inside; a cooling assembly 2 disposed inside the enclosure body 1 for supplying coolant into the enclosure body 1; cooling nozzles 210 of the cooling assembly 2 corresponding to each GPU storage slot 110 so that coolant is sprayed onto the corresponding GPU storage slot 110; and an exhaust pipe 13 disposed on the top edge of the enclosure body 1 for discharging the steam formed after the coolant in the enclosure body 1 evaporates.
[0045] See appendix Figure 2 To be continued Figure 4In some embodiments, this immersion cooling enclosure uses several GPU storage slots 110 provided inside the enclosure body 1 to place the GPUs to be used. Cooling components 2 inject coolant into the enclosure body 1 so that multiple GPUs are immersed in the coolant to achieve heat dissipation. At the same time, the cooling nozzles 210 of the cooling components 2 correspond to the positions of each GPU storage port so that the coolant can be directly sprayed onto the corresponding GPU surface, thereby breaking through the air film on the GPU surface and allowing the GPU surface to fully contact the coolant. The steam formed after the coolant evaporates inside the enclosure body 1 is discharged through the vent pipes 13 opened on the enclosure body 1, realizing a two-phase cooling cycle and improving heat exchange efficiency.
[0046] In some embodiments, the housing body 1 includes a cover plate 12 and a receiving groove 11; a GPU storage position 110 is disposed in the receiving groove 11; and the depth of the receiving groove 11 is configured to be greater than the height of the GPU, so that the GPU can be completely submerged in the receiving groove 11 after being installed in the GPU storage position 110. Specifically, the spray plate in the cooling assembly 2 covers the top of the receiving groove 11, thereby covering the GPU in the receiving groove 11. Coolant is introduced into the spray plate through the inlet pipe 14 provided in the cooling assembly 2. Since the cover plate 12 of the housing body 1 covers the spray plate, the coolant will flow into the central concave surface 21 of the spray plate through the cooling channel 22. After the central concave surface 21 is filled with coolant, the coolant is sprayed out through the cooling nozzle 210 and sprayed onto the corresponding GPU surface.
[0047] As an optional embodiment, in order to make the coolant spray uniform and continuous, a nozzle can be provided in the cooling spray hole 210. When the liquid in the central concave surface 21 is filled to a level exceeding a preset pressure, the nozzle is opened and the liquid is sprayed outward.
[0048] See appendix Figure 5 and attached Figure 6 In some embodiments, the GPU storage locations 110 are arranged in an N×M pattern; where N represents N rows and M represents M columns. Specifically, the number of GPUs is preferably configured as 8, where N is 2 and M is 4, that is, the GPUs are arranged in a two-row, four-column pattern. Meanwhile, the number of cooling nozzles 210 is the same as the number of GPUs, and their arrangement corresponds one-to-one.
[0049] In some embodiments, the number of GPUs is preferably configured to be 11, where N is 2 and M is 5, that is, the GPUs are arranged in two rows and five columns, with one GPU placed on either side of each row to form an odd-numbered configuration. Meanwhile, the number of cooling nozzles 210 is the same as the number of GPUs, and their arrangement corresponds one-to-one.
[0050] In some embodiments, the housing 1 is further provided with a CPU storage position 111 and a power supply storage position 112. The CPU storage position 111 and the power supply storage position 112 are located on both sides of the GPU storage position. Since the CPU uses high voltage power supply and the GPU uses low voltage power supply, placing the power supply next to the GPU shortens the high voltage power supply line and provides power supply stability.
[0051] In summary, this immersion cooling enclosure uses several GPU storage slots 110 within the enclosure body 1 to house the GPUs to be used. Coolant is injected into the enclosure body 1 through the cooling assembly 2, allowing multiple GPUs to be immersed in the coolant for heat dissipation. Simultaneously, the cooling nozzles 210 of the cooling assembly 2 correspond to the positions of each GPU storage port, allowing the coolant to be directly sprayed onto the corresponding GPU surface. This breaks through the air film on the GPU surface, ensuring that the GPU surface can fully contact the coolant. The steam formed after the coolant evaporates inside the enclosure body 1 is discharged through the vent pipe on the enclosure body 1, achieving a two-phase cooling cycle and improving heat exchange efficiency.
