Description

Cross-reference to related applications

[0001] This application claims the benefit of U.S. Provisional Patent Application Serial No. 63 / 734,697, filed December 16, 2024, pursuant to 35 USC §119(e), which is incorporated herein by reference in its entirety. Technical Field

[0002] This disclosure relates to cold plates, and more specifically to cold plates with airfoil-shaped fins for use in data center cooling systems. Background Technology

[0003] Buildings or facilities with numerous electronic devices consume significant amounts of electricity. These devices generate unwanted high temperatures during use, which must be removed to prevent malfunctions. In various buildings and facilities, particularly data centers, the increasing demand for computing power due to the introduction of generative artificial intelligence (AI) necessitates thermal systems that provide increased cooling density. A common method for cooling electronic devices or servers includes air cooling. For example, server racks are already cooled using air-based thermal management techniques. However, air cooling is insufficient for cooling next-generation servers.

[0004] Therefore, server cooling in data centers is shifting from air cooling to more efficient fluid cooling solutions. Fluid cooling, also known as liquid cooling, offers several benefits, including reduced energy costs, a smaller carbon footprint, increased power density, targeted cooling options, and significantly improved heat transfer, thus greatly enhancing energy efficiency. Furthermore, efficient cooling allows for more powerful server components, including higher processor clock speeds, thereby significantly increasing power density within servers and throughout the data center.

[0005] Liquid cooling systems include chip-level cold plate liquid cooling systems and immersion liquid cooling systems. Cold plate liquid cooling systems have metal chambers directly on the server chip and achieve direct cooling through the circulation of coolant. Direct-to-chip cooling integrates the cooling system directly into the computer chassis. Coolant is piped to cold plates located directly next to components such as the central processing unit (CPU), graphics processing unit (GPU), and memory cards. Small fluid channels transport the coolant to each plate, where it carries heat away from the components below. The warm liquid then circulates to a cooling unit or heat exchanger. After the warm liquid has been cooled, it is then circulated back to the cold plate.

[0006] Several factors influence the performance and suitability of cold-rolled steel plates, and different factors are important for different applications. Some important factors include production cost and ease of relatively large-scale production. Additionally, cold-rolled steel plate heat exchange structures typically utilize large heat transfer surface areas, usually in the form of fins, the geometry of which determines the performance of the cold-rolled steel plate. Traditional cold-rolled steel plate fins are square, triangular, or cylindrical in shape, but these blunt shapes often create flow separation zones, leading to a deterioration in the cold-rolled steel plate's performance. This is particularly detrimental in two-phase flows, where complete evaporation of the cooling fluid can occur on the rear surface of the fins, resulting in drying and effectively eliminating the fins' ability to transfer heat in that area. For example, Figure 1 An example internal structure 100 of a cold plate according to a conventional design is shown. This example illustrates the internal structure 100 of fins, each fin having a cross-sectional shape of a rectangular prism (e.g., a cuboid). Fins utilizing this shape, such as... Figure 2 As shown in Simulation 200, flow separation may occur on the downstream side of the fins, thereby reducing the liquid cooling efficiency during operation.

[0007] Therefore, a cooling solution is needed to improve heat transfer as fluid passes through a cold plate. Furthermore, a low-cost liquid-cooled cold plate is required that can make thermal contact with heat-generating components / devices while reducing energy costs when using high-power next-generation electronics. Summary of the Invention

[0044] It is known that data center equipment generates a significant amount of heat, which must be controlled in various ways to keep the equipment operational. While it is impractical to include an exhaustive list of the functions and types of equipment that may be found in the data centers of enterprises or other organizations, for the purposes of this disclosure, the term "data center equipment" or a similar term will be used to refer to any type of heat-generating component that one may find useful within the protected environment of an organization's data center or other facilities used to collect and install computer systems, electronic devices, or controllers. Such data center equipment typically includes, but is not limited to, computer systems, electronic devices, data storage systems, communication equipment, network equipment, information technology equipment, and their components and parts, such as, but not limited to, servers, chips, processors, motherboards, sound cards, graphics cards, storage devices, data storage devices, modems, and any other devices or components that are now or may be found useful in the art in the future.

[0045] As mentioned above, air-based cooling technologies are limited in their heat transfer capabilities, thus liquid cooling technologies may be necessary for thermal management of high-power, next-generation electronic devices. One such liquid cooling technology is a cold plate. A cold plate typically comprises a hollow plate, hollow channels, and / or similar structures with high thermal conductivity, through which a cooling fluid circulates. The cold plate is typically mounted directly to a heat-generating device, such as a CPU or GPU. The device heats the cold plate, which transfers heat to the cooling fluid. Typically, the fluid transfers heat to the outside of the adjacent electronic device / cold plate environment, reaching a separate heat dissipation unit. The fluid may remain in the same phase as it is heated in the cold plate (e.g., the fluid may enter the cold plate as a liquid and leave as a liquid), or the fluid may change phase as it is heated (e.g., from liquid to vapor). Flows that undergo a phase change through a cold plate are called two-phase flows, while flows that remain in a single state are called single-phase flows.

[0046] When designing cold plates, many factors influence their performance. This disclosure relates to internal structures that improve heat transfer and enhance capacity. The shape of these structures can significantly improve the performance of a cold plate for a given set of heat capacity and power requirements. Typically, the cold plate structure takes the form of internal fins in thermal communication with the cooling fluid, wherein the geometry, density, and arrangement of these fins determine the performance of the cold plate.

[0047] The internal fin structure of the cold plate described in this article can have a teardrop shape (e.g., an airfoil shape) such as that used for aircraft wings.

[0048] Note that, for the purposes of this disclosure, unless otherwise stated, the terms "airfoil," "airfoil shape," etc., include airfoil shapes with any degree of radian or no radian (i.e., zero radian). For example, having radian means that the airfoil bends (e.g., a U-shape, etc.) by a certain amount (e.g., 5 degrees), wherein the leading and trailing portions form an angle of non-zero angle (e.g., an angle measured between two tangents at two points along the arc of the airfoil's cross-sectional shape). "Airfoil" can include any suitable shape, such as a teardrop shape with a rounded nose (i.e., leading edge) and a tapering (i.e., pointed) tail (i.e., trailing edge). As shown in Figure 5A, airfoil shapes can be perfectly symmetrical and have zero radian. Figure 5B As shown, the airfoil shape may include some radians (e.g., non-zero radians, such as at least 40 degrees of radians). Figure 5B As shown, in contrast to a rounded leading edge, the shape of the fins can be relatively pointed / tapered at the leading edge.

[0049] The airfoil shape can include a thickness between approximately 20% and 40% of the chord length.

[0050] This shape prevents flow separation and dry areas behind each fin, thereby increasing heat transfer potential and reducing pressure drop across the cold plate. Compared to cylindrical or rectangular fins, airfoil-shaped fins can have, for example, ten times less flow resistance and double the heat transfer surface area for a given cross-section, while improving heat transfer capacity and cold plate power requirements.

[0051] The exemplary implementations presented herein can be applied to single-phase or two-phase cold plates, but are envisioned for exemplary use in two-phase cooling.

[0052] Air or other gases can be used as cooling media in cold plates. However, liquid cooling is typically used because liquids are denser than gases, allowing more thermal mass to be used to absorb heat from electronic devices. Furthermore, liquids have higher thermal conductivity, so heat can be transferred much faster than that transferred through gases. Additionally, liquids can absorb and transfer more heat than a comparable amount of gas.

[0053] Figure 3 A perspective view of a cold plate 300 according to one or more embodiments of the present disclosure is shown. Figure 4 One or more embodiments according to this disclosure are shown. Figure 3 The internal structure of the cold plate 300 is 400.

[0054] In some embodiments, the cold plate 300 includes a housing 302 or enclosure having one or more openings. For example, the openings may include an inlet 304 for receiving fluid and an outlet 306 for discharging fluid. The inlet 304 and outlet 306 may be formed on the top of the housing 302 as shown. However, the location of the inlet 304 and outlet 306 is not limited thereto. The inlet 304 and outlet 306 may be formed on the side or bottom of the housing 302; alternatively, one opening may be formed on the top and another on the side or bottom, and so on. The location of these openings may affect the flow pattern within the housing 302. Additionally, the shape of such openings may be configured to correspond to flow supply lines and flow discharge lines. In some embodiments, the flow pattern will tend to follow the supply and discharge lines, but certain structures within the housing 302 can alter the flow pattern.

[0055] The cold plate 300 may also include an internal structure 308. The internal structure 308 may be integrally formed with the housing 302 as a monolithic body. Alternatively, the housing 302 and the internal structure 308 may be formed separately and attached to each other. The internal structure 308, which is described in further detail below, may include fins that are in close contact with the top and bottom inner surfaces of the housing 302 (e.g., without gaps relative to the top and bottom inner surfaces of the housing 302).

[0056] Furthermore, the housing 302 and the internal structure 308 can be formed of the same material or different materials. For example, the housing 302 and the internal structure 308 can be formed of polymer-based materials, such as thermoplastic or thermosetting resins. However, other materials such as copper, aluminum, titanium, steel, gold, or even non-metallic materials such as graphite or ceramics can also be used.

[0057] The fins of the internal structure 308 can be arranged in any suitable configuration known in the art or disclosed herein. In some embodiments, the fins can be spaced apart from each other in a regular pattern (e.g., a grid and / or repeating pattern) as shown in the figures. In some embodiments, the fins can be arranged in an irregular pattern (e.g., non-repeating).

[0058] Figure 4 The internal structure 400 of a cold plate 300 according to one or more embodiments of the present disclosure is shown. Figure 3 The internal structure 308 and the corresponding internal structure 400 may include fins 402. The size and number of fins 402 may vary, and the fins may be arranged in rows and columns.

[0059] As shown, spaces / openings 404 and 406 may exist (e.g., regions without fins 402, such as regions defined by the absence of fins 402), which may correspond to and be aligned with the inlet 304 and outlet 306 of the housing 302, respectively, to allow fluid flow through the spaces / openings 404 and 406 undisturbed. For example, as shown, fewer or no fins 402 may be located near the opening.

[0060] Figure 5A shows a side view and a top view of the internal structure of a cold plate according to one or more embodiments of the present disclosure. Figure 5B The illustration shows an airfoil-shaped fin according to one or more embodiments of the present disclosure and representative streamlines of fluid flow along the fin surface.

[0061] As shown in Figure 5A and Figure 5B The cold plate shown, with its airfoil-shaped fins, can promote adhered flow (e.g., prevent separation flow) while reducing drag. For example, adhered flow can be characterized as a fluid streamline that remains in close proximity to the surface throughout the flow path, where the boundary layer remains adhered and does not separate. For instance, a first flow 502a flowing on one surface of the airfoil-shaped fin can continue its streamlined flow motion to adjacent aligned fins in the same row. Similarly, a second flow 504a can continue from one fin to another on the opposite side of the fin. Figure 5BThe fluid streamlines 502b and 504b also illustrate the attached flow. The airfoil streamlines are depicted along paths around the airfoil in the velocity tangential direction. The advantages of creating these airfoil patterns can be similar to those in other applications such as aircraft wings. Implementations can include continuously setting and aligning airfoil-shaped fins to create a variety of continuous airfoil streamline patterns, which can be related to, for example, those described above... Figure 2 The flow separation mentioned is contrasted with that formed by the conventional fins of the cold plate. A continuous airfoil streamline pattern can maintain laminar characteristics through multiple rows of fins, thereby reducing turbulent mixing losses. For example, the Reynolds number of the flow can be kept below the threshold to maintain laminar boundary layer adhesion along the fin surface.

[0062] Reference Figure 5B The internal structure of the fins can be configured with fluid streamlines 502b, 504b oriented in slightly alternating directions (e.g., curved in a first direction and curved in a second opposite / reversed direction). This can reflect (i.e., reorient) the streamlines 502b, 504b in a certain sense. For example, fins in adjacent rows can be staggered along the flow direction such that streamlines departing from the trailing edge of the fins in the first row are oriented toward the leading edge of the fins in the second row (e.g., exactly inside the leading edge). This can be repeated continuously back and forth along the flow direction using curved fins. Fins in two adjacent rows can include opposing concave surfaces to cause multiple reorientations (e.g., reflections).

[0063] Figure 6 , Figure 7A and Figure 7B This further supports the advantages of airfoil-shaped fins.

[0064] For example, Figure 6 A computational fluid dynamics (CFD) analysis 600 of the flow of a cold plate according to one or more embodiments of the present disclosure is shown. As illustrated, in the relatively high flow region 602, with Figure 2 Compared to the simulation 200, the flow showed reduced separation and improved cooling.

[0065] Figure 7A The illustration shows one or more embodiments corresponding to this disclosure. Figure 6 A magnified view of the flow streamlines from CFD analysis at 700°. Figure 7B It shows Figure 1 CFD analysis of the internal structure of a conventional cold plate 100 702.

[0066] In particular, Figure 7A and Figure 7BComparing embodiments of this disclosure (e.g., fins 708 with an airfoil shape) with conventional structures (e.g., rectangular fins 706), as shown, the dry region 704 of the conventional internal structure 100 (i.e., the region through which almost no liquid passes) can significantly reduce the amount of surface area available for heat transfer in the rectangular fins 706. In contrast, as... Figure 7A As shown, embodiments of this disclosure can increase the surface area of ​​fins 708 that can be used to provide cooling for cold plates and / or heated servers that require cooling.

[0067] Figure 8 A flowchart of a method 800 for manufacturing a cold plate according to one or more embodiments of the present disclosure is shown. The cold plate 300 is an exemplary carrier for performing method 800. However, method 800 is not necessarily limited to the foregoing embodiments, and unless otherwise stated, method 800 should be extended to any acceptable system or apparatus now or thereafter known to those skilled in the art.

[0068] Method 800 may include step 802 of forming the lower body of housing 302. (Return to reference) Figure 3 The housing 302 can have a cubic shape with six walls / body sections, such as an upper body, a lower body, and four side bodies. The lower body can have a flat rectangular shape.

[0069] Method 800 may include step 804 of continuously forming fins on a lower body. Here, the lower body, the fins, and the side bodies (e.g., the four outer sides) of the shell 302 may be integrally formed into a single body, such that the fins and the side bodies can be formed together. Continuous formation can be achieved through a layer-by-layer additive manufacturing process, in which each successive layer is bonded to the previous layer.

[0070] Method 800 may include step 806 of continuously forming the upper body of the shell.

[0071] The shell and fins can be formed together as a single unit or separately by any suitable method, such as injection molding or 3D printing. This simple manufacturing process enables cost reduction and time savings, and promotes environmentally friendly manufacturing processes by enabling material recycling and reuse, reducing water / coolant usage, and using biodegradable filaments.
