Description

Technical Field

[0001] The present invention relates to a device for suppressing the thermal wake flowing downward from a heat-generating component. Background Art

[0002] A thermal wake is a high-temperature and low-velocity region immediately following a heat-generating component (e.g., in an electronic system). The thermal wake is caused by turbulent vortical bubbles, which prevent thermal mixing and thus result in a high-temperature region. Different from some other problems related to cooling, the thermal wake cannot be solved by increasing the air flow rate in the electronic system. Instead, due to the nature of turbulence, an increased air flow velocity creates larger vortical bubbles, thus causing worse local hot spots and longer thermal tails of the thermal wake. Therefore, a large space is usually left behind a high-power component to avoid negative impacts on its downstream components from the thermal wake region behind the high-power component.

[0003] However, with the growth of performance requirements, high-density systems are becoming the mainstream in the market, thus giving priority to any available space, including the thermal wake region. Therefore, a solution is needed to suppress the local hot spots of the thermal wake. The present invention aims to solve these problems. Summary of the Invention

[0004] The terms of embodiments and similar terms (e.g., implementations, configurations, features, examples, and options) are intended to generally refer to all the subject matters of the present invention and the appended claims. Several statements containing these terms should be understood not to limit the subject matter described herein or the meaning or scope of the appended claims. The embodiments of the present invention covered herein are defined by the appended claims, rather than the summary of the invention. This summary of the invention is a high-level overview of various features of the present invention and introduces some concepts described in more detail in the following embodiment paragraphs. This summary of the invention is not intended to identify the key or essential features of the claimed subject matter, nor is it intended to be used independently to determine the scope of the claimed subject matter. The subject matter should be understood by referring to the appropriate parts of the complete specification of the present invention, any or all of the drawings, and each claim.

[0005] According to certain features of the present invention, a hot wake suppressor includes a spacing grid and a plurality of torsion plates. The spacing grid is defined by a plurality of longitudinal ribs and a plurality of transverse ribs that form a plurality of intersection points. The plurality of longitudinal ribs includes M longitudinal ribs. The plurality of transverse ribs includes N transverse ribs. The plurality of intersection points includes (M - 1)×(N - 1) intersection points. The spacing grid has an outer frame including two longitudinal ribs of the several longitudinal ribs and two transverse ribs of the several transverse ribs. The spacing grid contains a plurality of intersection points. The plurality of torsion plates extends from the spacing grid in a downward direction of a heat generating component. The plurality of torsion plates are periodically arranged on at least some of the plurality of longitudinal ribs and at least some of the plurality of transverse ribs. A subset of the plurality of torsion plates is arranged to break up a hot wake created by the heat generating component into a plurality of sub-vortices in the downward direction.

[0006] In some examples, the plurality of intersection points includes a first intersection point and a second intersection point. The first intersection point is between a first pair of adjacent torsion plates, and the second intersection point is between a second pair of adjacent torsion plates. The first pair of adjacent torsion plates extends from a longitudinal rib of the plurality of longitudinal ribs. The second pair of adjacent torsion plates extends from a first transverse rib of the plurality of transverse ribs. The second intersection point is adjacent to the first intersection point. In some such other examples, the first intersection point and the second intersection point are formed by the same longitudinal rib. In some such other examples, the first intersection point and the second intersection point are formed by the same transverse rib.

[0007] In some examples, a first torsion plate of the first pair of adjacent torsion plates extends from the longitudinal rib at an upward inclination angle, and a second torsion plate of the first pair of adjacent torsion plates extends from the longitudinal rib at a downward inclination angle. In some examples, a first torsion plate of the second pair of adjacent torsion plates extends from the transverse rib at a first angle, and a second torsion plate of the second pair of adjacent torsion plates extends from the transverse rib at a second angle.

[0008] In some examples, the plurality of intersection points further includes a third intersection point and a fourth intersection point. The third intersection point is between a third pair of adjacent torsion plates, and the fourth intersection point is between a fourth pair of adjacent torsion plates. The third pair of adjacent torsion plates extends from a second transverse rib of the plurality of transverse ribs. The third intersection point is adjacent to the first intersection point. The fourth pair of adjacent torsion plates extends from a third transverse rib of the plurality of transverse ribs. The fourth intersection point is also adjacent to the first intersection point.

[0009] In some examples, the plurality of longitudinal ribs are equally spaced. In some examples, two adjacent longitudinal ribs and two adjacent transverse ribs form four intersection points. In some such examples, the four intersection points define a rectangular opening, through which the formation of a sub-vortex is caused. In some such examples, the rectangular opening is square.

[0010] According to certain features of the present invention, a hot wake suppression system includes a heating component and a hot wake suppressor located downstream of the heating component. The heating component produces a hot wake in a downward direction. The hot wake suppressor includes a spacing grid and a plurality of torsion plates that extend from the spacing grid at an angle. The spacing grid is defined by a plurality of longitudinal ribs and a plurality of transverse ribs that form a plurality of intersection points. The plurality of torsion plates are arranged periodically on the plurality of longitudinal ribs and the plurality of transverse ribs such that a subset of the plurality of torsion plates is arranged to break up the hot wake into a plurality of sub-vortices in the downward direction.

[0011] In some examples, the plurality of torsion plates extend from a side of the spacing grid facing away from the heating component. In some examples, the angle is proportional to a length of the hot wake. In some examples, a size of each torsion plate is proportional to a length of the hot wake.

[0012] In some examples, the hot wake suppression system is a computing system. In some such examples, the heating component is a memory module. In some examples, the hot wake suppressor is configured to localize an air flow from the heating component into a plurality of sub-vortices, thereby enhancing thermal mixing and reducing an impact of the hot wake. In some examples, adjacent torsion plates of the plurality of torsion plates extend from the spacing grid in different directions.

[0013] According to certain features of the present invention, a suppressor is disclosed below for suppressing a hot wake generated by a computing device in a downward direction. The suppressor includes a grid and a plurality of plates formed by the intersection of a plurality of longitudinal ribs and a plurality of transverse ribs, and the plurality of plates are attached to the grid and extend from the grid. Each plate is configured to be angled to direct the hot wake in the downward direction. A subset of the plurality of plates is configured to be angled in at least four different directions such that the subset of the plurality of plates is arranged to break up the hot wake into one or more sub-vortices in the downward direction.

[0067] The present invention relates to a hot wake suppressor, which has (i) a spacing grid defined by a plurality of longitudinal ribs and a plurality of transverse ribs, and (ii) a plurality of torsion plates extending from the spacing grid and being periodically arranged on the plurality of longitudinal ribs and the plurality of transverse ribs. The hot wake suppressor assists in suppressing local hot spots of a hot wake descending from a heat generating component by breaking up vortex bubbles and enhancing heat mixing.

[0068] Multiple embodiments are described with reference to the accompanying drawings, and like reference signs are used throughout the drawings to designate like or equivalent elements. The drawings are not drawn to scale, and the drawings are provided only to show the features and characteristics of the present invention.

In addition, not all of the shown actions or events are required to implement certain features and characteristics of the present invention.

[0070] Referring to Figure 1 , a top perspective view of a hot wake suppression system 100 is shown, depicting certain features of the present invention. The hot wake suppression system 100 includes a computing system 110 and a hot wake suppressor 130. The computing system 110 includes a motherboard 112, two dual in-line memory modules (DIMMs) 116 and 118, and a heat sink 114 (with a chipset). The dual in-line memory modules 116 and 118 are mounted on the motherboard 112, and the heat sink 114 is mounted between the dual in-line memory module 116 and the dual in-line memory module 118. In this example, the dual in-line memory modules 116 and 118 are the main heat-generating components of the system. The dual in-line memory modules 116 and 118 typically generate hot spots of hot wakes in the downstream direction of each immediate airflow direction 120. To reduce and / or suppress the hot wakes, the hot wake suppressor 130 is located downstream of the dual in-line memory module 116 and the dual in-line memory module 118.

[0071] Figure 2 A front perspective view of a hot wake suppressor 230 is shown, depicting certain features of the present invention. The hot wake suppressor 230 is associated with Figure 1is the same or similar to the shown hot wake suppressor 130, where like reference numerals denote like elements, except that the hot wake suppressor 230 includes fewer lateral ribs 236 than the hot wake suppressor 130. The hot wake suppressor 230 includes a spacing grid 232 defined by a plurality of longitudinal ribs 234 and a plurality of lateral ribs 236. The outer frame of the spacing grid 232 is formed by two outermost longitudinal ribs 234 and two outermost lateral ribs 236. Each longitudinal rib 234 extends from a first side 240 of the spacing grid 232 to an opposite second side 242. The distance between the first side 240 and the second side 242 defines a length D1 of the spacing grid 232. Each lateral rib 236 extends from a top 244 of the spacing grid 232 to a bottom 246. The distance between the top 244 and the bottom 246 defines a height D2 of the spacing grid 232. In this example, the plurality of longitudinal ribs 234 and the plurality of lateral ribs 236 are rigid and linear (e.g., straight), and thus the shape of the spacing grid 232 is rectangular.

[0072] The spacing grid 232 includes a plurality of intersection points formed by the plurality of longitudinal ribs 234 and the plurality of lateral ribs 236. For example, the longitudinal rib 234a (i.e., the second longitudinal rib counted from the top 244 of the spacing grid 232) and the lateral rib 236a (i.e., the eighth lateral rib counted from the first side 240 to the second side 242 of the spacing grid 232) intersect at the intersection point 238a. Except for the outermost ribs, two adjacent longitudinal ribs 234 and two adjacent lateral ribs 236 form four intersection points that define a rectangular opening (or cell). In this example, the plurality of longitudinal ribs 234 are equally spaced, and the plurality of lateral ribs 236 are equally spaced; thus, the rectangular openings are square. Generally, smaller openings can better reduce and / or suppress the hot wake. However, it is more difficult to fabricate a hot wake suppressor with smaller openings. In this example, for a hot wake suppressor behind a dual in-line memory module (e.g., 8x DDR-5), an opening with a length or width of 2 mm to 5 mm is preferred.

[0073] For the hot wake suppressor of the present invention (e.g., the hot wake suppressor 130 or 230), if the plurality of longitudinal ribs include a number M of longitudinal ribs, and the plurality of lateral ribs include a number N of lateral ribs, then the plurality of intersection points include a number (M - 1)×(N - 1) of intersection points. In the example of the hot wake suppressor 230, there are five (5) longitudinal ribs 234 and sixteen (16) lateral ribs; thus the hot wake suppressor 230 includes (5 - 1)×(16 - 1) = 60 intersection points.

[0074] Referring to Figure 3 , a front perspective view showing the hot wake suppressor 130. The hot wake suppressor 130 is the same as Figure 2is the same as or similar to the shown hot wake suppressor 230, where like reference numerals denote like elements, except that the hot wake suppressor 230 includes fewer transverse ribs 236 than the hot wake suppressor 130. As Figure 3 shown, the longitudinal rib 334a (i.e., the second longitudinal rib counted from the top 344 of the spacing grid 332) and the transverse rib 336a (i.e., the seventh transverse rib counted from the first side 340 to the second side 342 of the spacing grid 332) intersect at the intersection point 338a. For the hot wake suppressor 130, there are five (5) longitudinal ribs and eighteen (18) transverse ribs; thus, the hot wake suppressor 130 includes (5 - 1)×(18 - 1) = 68 intersection points.

[0075] Referring Figure 4 , a rear perspective view of the hot wake suppressor 130 is shown. Figure 4 The shown hot wake suppressor 130 is the same as or similar to the Figure 3 shown hot wake suppressor 130, where like reference numerals denote like elements. The hot wake suppressor 130 further includes a plurality of twisted plates that extend downwardly from the spacing grid 332 in the air flow direction 120. The plurality of twisted plates are arranged periodically on the plurality of longitudinal ribs and the plurality of transverse ribs.

[0076] The enlarged view shows a pair of twisted plates 450a and 450b adjacent to the intersection point 338a. Specifically, the twisted plates 450a and 450b extend from the longitudinal rib 334a, and the twisted plates 450a and 450b are located on opposite sides of the transverse rib 336a. The twisted plates 450a and 450b extend from the spacing grid 332 in different directions. In this example, the twisted plate 450a extends from the longitudinal rib 334a at an upward inclination (i.e., toward the air flow direction 120 and the top 344). The twisted plate 450b extends from the longitudinal rib 334a at a downward inclination (i.e., toward the air flow direction 120 and the bottom 346).

[0077] Three intersection points, the intersection point 338b, the intersection point 338c, and the intersection point 338d are adjacent to the intersection point 338a. Both the intersection points 338b and 338c are formed on the same longitudinal rib 334a as the intersection point 338a. The intersection point 338d is formed on the same transverse rib 336a as the intersection point 338a. The three intersection points 338b, 338c, and 338d are each located between a corresponding pair of twisted plates that extend from a transverse rib on opposite sides of a longitudinal rib (instead of extending from a longitudinal rib on opposite sides of a transverse rib, as in the case of the intersection point 338a). A first twisted plate of each corresponding pair of twisted plates extends from the transverse rib at a first angle (i.e., toward the air flow direction 120 and the first side 340). A second twisted plate of each corresponding pair of twisted plates extends from the transverse rib at a second angle (i.e., toward the air flow direction 120 and the second side 342).

[0078] Reference Figure 5 , a rear perspective view of the intersection 338a of the hot wake suppressor 130 is shown. The intersection 338a is located between the torsion plates 450a and 450b. Reference Figure 6 , showing Figure 5 a front side view 600A and a rear side view 600B of the intersection 338a. In some embodiments, the torsion plate 450a is inclined upward at an angle α (e.g., about 30 to 60 degrees). The torsion plate 450b is inclined downward at the angle α. In some embodiments, the angle α is proportional to the length of a hot wake generated by a heat generating component (the hot wake suppressor 130 ( Figure 1 ) is placed behind the heat generating component). The size of the spacing grid 332 ( Figure 3 ) and the angle α of the torsion plate can both be adjusted based on the encountered hot wake. For example, when the hot wake of the heat generating component is longer, the size of the torsion plate is larger and / or the angle α is larger.

[0079] The torsion plate 450a and the torsion plate 450b extend from the spacing grid 332 by a length L (e.g., about 2 mm to 8 mm). The torsion plates 450a and 450b each have a thickness T (e.g., about or less than 2 mm), and a width W (e.g., about half of the opening). Additionally or alternatively, in some embodiments, the size and / or scale of each torsion plate is proportional to the length of the hot wake generated by the heat generating component (the hot wake suppressor is placed behind the heat generating component). In some embodiments, the thickness T of each torsion plate is approximately 1 / 2 of the width W of the torsion plate. In some embodiments, the width W of each torsion plate is approximately 1 / 2 of the width of the opening. In some embodiments, the length L of each torsion plate is approximately 1 / 2 of the width of the opening. In some embodiments, the ratio of the width W to the length L of each torsion plate is approximately 1:1.

[0080] Reference Figure 7 , a top perspective view of the hot wake suppression system 100 is shown in accordance with certain features of the present invention. Figure 7 The hot wake suppression system 100 shown in Figure 1 is the same as or similar to the hot wake suppression system 100 shown in Figure 7 , where the same reference signs denote the same elements, except that Figure 3 an additional first section plane P1 and a second section plane P2 are additionally shown. The air flow direction 120 shows air flowing from the heat generating components (e.g., dual in-line memory modules 116 and 118) through the hot wake suppressor 130, traveling to the first section plane P1 (at the spacing grid 332 of the hot wake suppressor 130 (

[0081] When the hot wake flows through the hot wake suppressor 130, the spacing grid 332 ( Figures 3 to 4 ) localizes the hot wake into several small vortices. For example, Figure 8 illustrates the heat flow through four openings adjacent to the intersection point 338a in the first cutting plane P1 ( Figure 7 ). The heat flow is localized into several small vortices, as Figure 8 shown in the heat map illustration.

[0082] Figure 9 Illustrates the heat flow through the intersection point 338a in the second cutting plane P2 ( Figure 7 ) according to certain features of the present invention. As shown, the air is redirected into small vortices by the torsion plate, either counterclockwise or clockwise. In this example, there are two counterclockwise small vortices 960 and 962, and two clockwise small vortices 964 and 966. The small vortex 960 travels in the direction 970. The small vortex 962 travels in the direction 972. The small vortex 964 travels in the direction 974. The small vortex 966 travels in the direction 976. Thus, the air from each small vortex is mixed with the air from other small vortices. The temperature is then averaged to a lower value, thereby reducing and / or suppressing the hot spots of the hot wake. The enhanced thermal mixing between the vortices reduces the preheating temperature and / or the hot wake generated by the heat generating component.

[0083] Referring to Figure 10 , illustrates a heat map comparison between a computing system 110 without a hot wake suppressor and a computing system 110 with a hot wake suppressor (e.g., hot wake suppressor 130) according to certain features of the present invention. In this example, the hot wake suppressor 130 is placed approximately 30 mm away from the computing system 110. In this example of a computational fluid dynamics (CFD) study, a dual in-line memory module is used as an example heat generating component to demonstrate the performance of the hot wake suppressor 130. The computational fluid dynamics simulation results show that the hot wake suppressor 130 is effective in reducing the downstream temperature of the heat generating component (e.g., dual in-line memory module).

[0084] In a system without a hot wake suppressor, there is a long hot wake behind the dual in-line memory module (as shown by the upper circle in Figure 10 ), with a temperature as high as 65.6 °C and covering approximately 30 mm behind the dual in-line memory module. However, the overall downstream temperature averages only around 46.5 °C. Therefore, there is a hot spot of the air flow created by the hot wake. By placing the hot wake suppressor 130 behind the dual in-line memory module, the heat flow is dispersed into several small vortices, redirected, and mixed with other small vortices. Thus, the hot wake in this case (as shown in Figure 10is significantly shorter than the thermal wake of a system without a thermal wake suppressor, as shown by the lower circle). The hot spot of the thermal wake is also reduced by 6.1 °C to 59.5 °C. This reduction in the hot spot is highly beneficial for a high-density system (e.g., a server system) in order to reduce the preheating effect from an upstream component to a downstream component.
