Description

Technical Field

[0001] The present invention relates to an apparatus for promoting nucleus boiling to cool a component that generates heat within a computing system, and more specifically, to a nucleus boiling apparatus that provides two separate nucleus boiling point layers. Background Technology

[0002] Two-phase boiling heat transfer is a thermal solution for densely powered components within computing systems. The latent heat of the phase change readily dissipates a significant amount of heat while maintaining the component temperature at its saturation point. Figure 1 This illustrates a situation where a core-shaped boiling plate 100 is in contact with a component (not shown) generating heat within a computing system (not shown). Due to this excellent heat dissipation performance, boiling heat transfer plays a crucial role in future thermal solutions. However, excessive heat dissipation and uneven distribution create localized hot spots, causing bubbles to coalesce into a bubble film in a downstream region. This reduces boiling heat transfer and, in the worst case, can cause component burnout. Figure 1 The bubble membrane 101 is shown relative to the core boiling plate 100.

[0003] To prevent this problem, please refer to Figure 2 A reinforced nucleus boiling plate 200 is commonly used to generate bubbles more uniformly on the surface. This reinforced nucleus boiling plate 200 is typically made of a highly thermally conductive material (e.g., copper) and includes a surface treatment, such as coating with microparticles or stamped dimples 202, to enhance nucleus boiling. Figure 2 Display, with Figure 1 Compared to the original nucleus-shaped boiling plate 100, the enhanced nucleus-shaped boiling plate 200 successfully enables steam bubbles to form more uniformly over almost all of its surface areas. However, it does not completely prevent large-deformation steam bubbles 201 in the center from affecting the heat dissipation of the entire enhanced nucleus-shaped boiling plate 200.

[0004] The present invention aims to provide a nucleo boiling device that solves the above-mentioned problems and other needs. Summary of the Invention

[0048] Figure 3A Showing a side view of a nucleus boiling device 300 according to a feature of the invention. The nucleus boiling device 300 includes a first set of multiple pipes 302, a second set of multiple pipes 304, and a base 306.

[0049] The base 306 is configured to mount a heat-generating component 10 (e.g., a processor) within a computing system to provide immersion cooling for the component 10 in a liquid-cooled computing environment. The base 306 utilizes an upper surface 306a ( Figure 3C ), the following surface 306b ( Figure 3BThe base 306 is defined by a plurality of side surfaces 306c to 306f. The plurality of side surfaces 306c to 306f include a first side surface 306f and a second side surface 306d opposite to the first side surface 306f. The base 306 may be made of a metal or a metal alloy, such as copper or an aluminum alloy. The primary purpose of the base 306 is to keep the first set of plurality of conduits 302 and the second set of plurality of conduits 304 substantially close to or abutting against the component 10. The diamond-hashed region of the base 306 represents the area where the first set of plurality of conduits 302 and the second set of plurality of conduits 304 extend through the base 306 to contact the component 10. In one or more embodiments, this contact may constitute direct contact between the base 306 and / or the plurality of conduits 302 and the plurality of conduits 304 and the component 10. Alternatively, this contact may involve the base 306 and / or the plurality of conduits 302 and the plurality of conduits 304 partially or completely contacting a thermal interface material 318 between the base 306 and the component 10. The thermal interface material 318 may improve heat transfer between the base 306 and / or the plurality of conduits 302 and the plurality of conduits 304 and the component 10.

[0050] A first set of multiple conduits 302 extends from a first side surface 306f of the base 306. The first set of multiple conduits 302 includes a first flat region 308 and a first transition region 310. In the first transition region 310, the first set of multiple conduits 302 is relative to... Figure 3A The orientation shown extends away from the base 306 along a first inclined direction relative to the base 306. In the first flat area 308, a first group of multiple pipes 302 extend outward from the base 306 in a fan-shaped arrangement, as follows: Figure 3B as well as Figure 3C As shown and further described. In the first transition region 310, all pipes within the first group of multiple pipes 302 are generally parallel to each other.

[0051] Similar to the first set of multiple conduits 302, the second set of multiple conduits 304 extends from the second side surface 306d of the base 306, opposite to the first set of multiple conduits 302 and the first side surface 306f. The second set of multiple conduits 304 includes a second flat region 312 and a second transition region 314. In the second transition region 314, the second set of multiple conduits 304 is related to... Figure 3A The orientation shown extends away from the base 306 along a second inclined direction relative to the base 306. In the second flat area 312, the second group of multiple pipes 304 extend outward from the base 306 in a fan-shaped arrangement, as follows: Figure 3B as well as Figure 3C As shown and further described. In the second transition zone 314, all pipes within the second group of multiple pipes 304 are generally parallel to each other.

[0052] To achieve improved immersion cooling, the distance between the second flat region 312 of the second set of multiple conduits 304 and the upper surface of the base 306 is greater than the distance between the first flat region 308 of the first set of multiple conduits 302 and the upper surface of the base 306. The second flat region 312 is located above the first flat region 308 on the base 306 to minimize the impact of bubble formation in one region on the other. Bubbles formed in one region can pass above or below the other region to reduce their impact on the opposite region. More specifically, the nucleus boiling device 300 can be positioned on component 10, which is located within a cooling liquid flow indicated by arrow 20 within a computing system. The first set of multiple conduits 302 can constitute the upstream region of the nucleus boiling device 300 within the fluid flow 20. The second set of multiple conduits 304 can constitute the downstream region of the nucleus boiling device 300 within the fluid flow 20. Therefore, the first group of multiple pipes 302 and the second group of multiple pipes 304 are arranged in a staggered manner, wherein the downstream region (e.g., the second group of multiple pipes 304) is higher than the upstream region (e.g., the first group of multiple pipes 302) relative to the base 306. The effect is that bubble formation in the upstream region affects bubble formation in the downstream region, and thus affects cooling, less than when the two regions are at the same level. With this design, the two flat regions where most boiling occurs become more efficient. Furthermore, the total boiling area can also be increased. Therefore, compared to existing core-shaped boiling plates 100 and 200 (respectively in…),… Figure 1 , Figure 2 (In China), the nucleus boiling device 300 can significantly improve heat transfer.

[0053] In one or more embodiments, in the first flat region 308, the surface of the first set of plurality of pipes 302 may include one or more of the aforementioned features that enhance nucleus boiling, such as microparticles or stamping recesses 320. Similarly, in one or more embodiments, in the second flat region 312, the surface of the second set of plurality of pipes 304 may include one or more of the aforementioned features that enhance nucleus boiling, such as microparticles or stamping recesses 320.

[0054] In one or more embodiments, a first group of multiple pipes 302 can be connected to a second group of multiple pipes 304 via a base 306, such that each pipe of the first group of multiple pipes 302 is connected to a corresponding pipe of the second group of multiple pipes 304 to form a single pipe. In one or more embodiments, a thermal interface material (e.g., material 318) may be present between the base 306 and the component 10.

[0055] In one or more embodiments, the first group of multiple conduits 302 may be arranged in a single layer, such as Figure 3AAs shown. In one or more embodiments, the second group of multiple conduits 304 may be arranged in a single layer, such as... Figure 3A As shown. Ideally, the first set of multiple conduits 302 and the second set of multiple conduits 304 are arranged in a single layer, with no other conduit above or below to improve nucleation. However, in one or more embodiments, the first set of multiple conduits 302 and the second set of multiple conduits 304 may be arranged in more than one layer.

[0056] The first group of multiple conduits 302 and the second group of multiple conduits 304 may include any number of conduits, depending on the amount of heat to be dissipated, the size of the base 306, etc. In one or more embodiments, the first group of multiple conduits 302 and the second group of multiple conduits 304 may each include eight conduits, such as... Figure 3B as well as Figure 3C show.

[0057] In one or more embodiments, in the first transition region 310, the first set of multiple conduits 302 are inclined relative to the base 306 in a first tilting direction at a first angle θ1. In the second transition region 314, the second set of multiple conduits 304 are inclined relative to the base 306 in a second tilting direction at a second angle θ2. In one or more embodiments, the second angle θ2 may be greater than the first angle θ1, such that the second set of multiple conduits 304 may extend to a higher horizontal plane or plane relative to the base 306 above the first set of multiple conduits 302, beyond the first set of multiple conduits 302 by a short distance.

[0058] According to the features of the present invention, Figure 3B A bottom view of the nucleo-boiling device 300 is shown. Figure 3C Showing a top view of the nucleus boiling apparatus 300. For convenience, Figures 3B to 3C The described embodiment is an example where each of the first set of multiple pipes 302 is connected to a corresponding pipe of the second set of multiple pipes 304 to form a single pipe spanning the nucleus boiling device 300. Therefore, the nucleus boiling device 300 includes eight pipes 316a to 316h. Furthermore, portions of the pipes 316a to 316h within the first flat region 308 and the second flat region 312 described above are shown fan-shaped or dispersed. This fan-shaped arrangement of the pipes 316a to 316h provides greater spacing between them, such that the nucleation effect of one pipe (e.g., 316a) on the nucleation of an adjacent pipe (e.g., 316b) is smaller compared to the case where the pipes 316a to 316h are not fan-shaped.

[0059] In one or more embodiments, the spacing between conduits 316a to 316h may be constant relative to the distance from the base 306. Alternatively, in one or more embodiments, the conduits in the first group of multiple conduits 302 in the first flat region 308, the second group of multiple conduits 304 in the second flat region 312, or both, may be spaced further apart. The distance relative to the base 306, and the distance relative to the center conduit (in... Figure 3B In the example shown, the central conduit is conduit 316d and 316e), or the spacing between conduits can be greater relative to the distance from both. Therefore, Figure 3B The distance D1 in the middle is less than Figure 3B The distance D2 is greater because pipes 316g and 316h are further from the center or midline of pipes 316a to 316h than pipes 316d and 316e, where pipes 316d and 316e roughly define the center or midline of pipes 316a to 316h. Again, this facilitates nucleation and reduces bubble binding in the outer pipes (e.g., 316a, 316b, 316g, and 316h).

[0060] As in Figure 3B as well as Figure 3C As further shown, in one or more embodiments, the cross-sectional areas of conduits 316a to 316h in the first flat region 308, the second flat region 312, or both, are greater than the cross-sectional areas of conduits 316a to 316h in the individual first transition region 310, the individual second transition region 314, or both. The larger cross-sectional areas of conduits 316a to 316h in the first flat region 308, the second flat region 312, or both provide additional surface area for nucleation.

[0061] Furthermore, in one or more embodiments, and in Figure 3B as well as Figure 3C The diagram further shows that the cross-sectional areas of conduits 316a to 316h in the first flat region 308, the second flat region 312, or both, increase relative to their distance from the base 306. This increased cross-sectional area of ​​conduits 316a to 316h relative to their distance from the base 306 provides additional surface area for nucleation.

[0062] In one or more embodiments, and as Figure 3B as well as Figure 3CAs shown, conduits 316a to 316h are sealed hollow metal conduits. In one or more embodiments, the sealed hollow metal conduits may include a fluid, such as a working fluid. When conduits 316a to 316h are in use, the working fluid may be selected to be in a liquid or gaseous state within the conduits. In one or more embodiments, conduits 316a to 316h may be solid.

[0063] In one or more embodiments, the combined width of the first group of multiple conduits 302, the combined width of the second group of multiple conduits 304, or both, may span a width less than that of the base 306. Alternatively, the combined width of the first group of multiple conduits 302, the combined width of the second group of multiple conduits 304, or both, may span a width approximately the same as that of the base 306.

[0064] Figure 4 as well as Figure 5 The computational fluid dynamics simulation results are displayed, showing the effect of the first set of staggered pipes 302 relative to the second set of staggered pipes 304 on the base 306 of the nucleus boiling device 300. For example... Figure 4 As shown, the void fraction is generated at the first set of multiple pipes 302, and then flows and concentrates above the base 306. However, relative to the liquid flow direction, the void fraction is below the base 306 and below the second set of multiple pipes 304 downstream of the first set of multiple pipes 302. Therefore, the interference of the nucleus boiling caused by the first set of multiple pipes 302 on the nucleus boiling caused by the second set of multiple pipes 304 is less than the interference of the nucleus boiling caused by the first set of multiple pipes 302 on the nucleus boiling caused by the second set of multiple pipes 304 if the multiple pipes 302 and the multiple pipes 304 were all on the same plane or horizontal plane above the base 306.

[0065] Reference Figure 5 The staggered multiple conduits 302 and 304 provide greater heat transfer capacity to transfer heat from component 10 to the surrounding fluid. Table 1 shows that, compared to an existing core-type boiling plate (e.g., Figure 2 The nucleosurfing device 300 provides better heat dissipation than a conventional nucleosurfing plate (e.g., plate 200). The nucleosurfing device 300 can reduce thermal resistance by up to 56%. Furthermore, compared to an existing nucleosurfing plate (e.g., plate 200), the nucleosurfing device 300 offers significantly better heat dissipation. Figure 2 The plate 200 and the nucleus boiling device 300 improve heat transfer capacity by up to 80%.
