Description

Technical Field

[0001] This disclosure relates to the use of matrix cooling plates for thermal management systems and methods. Background Technology

[0002] Electrical and mechanical components generate heat during operation. Excessive heat can cause components to malfunction or stop operating correctly. Therefore, an effective heat transfer strategy is crucial for ensuring component reliability and effectiveness.

[0003] A typical cooling plate may include copper tubing formed by computer numerical control (CNC). This tubing can be pressed or flattened into the base plate to closely match its unique shape. Alternatively, the tubing can be epoxy-bonded or otherwise securely attached to the base plate. Further processing of the tubing is then possible. Adapters can be brazed to the copper tubing for user assembly.

[0004] The base plate may include an aluminum sheet that is machined to define multiple copper tube channels, mounting holes, and machined removal sections to reduce overall weight. Therefore, a given cooling plate can be shaped into a specific configuration to suit a particular application. However, once a cooling plate design is finalized, it may be difficult to adapt to heat transfer applications that differ from its original design. Summary of the Invention

[0005] According to one aspect of this disclosure, coolant flow is directed through a cooling plate comprising a plurality of parallel channels, wherein portions of the parallel channels are selectively connected to each other to create one or more parallel flow, serial flow, or obstruction flow regions within the cooling plate.

[0006] In some embodiments, each of the plurality of channels may be open to an end surface of the cooling plate. Selectively connecting portions of the parallel channels to each other may include applying a sealing plate to an end of the cooling plate that connects at least some of the parallel channels to each other.

[0007] In some embodiments, applying a sealing plate to the end of a cooling plate can connect a first subset of parallel channels to each other and a second subset of parallel channels to each other.

[0008] In some embodiments, selectively connecting portions of the parallel channels to each other may include machining a plurality of transverse channels in a cooling plate such that each transverse channel intersects with at least some of the parallel channels.

[0009] In some embodiments, the method may further include extruding a cooling plate to form a plurality of parallel channels before machining the plurality of transverse channels.

[0010] In some embodiments, at least one of the plurality of lateral channels may intersect only with a subset of the parallel channels.

[0011] In some embodiments, selectively connecting portions of the parallel channels to each other may include positioning the valve at a junction formed where one of the transverse channels intersects with one of the parallel channels.

[0012] In some embodiments, positioning the valve at the intersection may include positioning the valve in one of the following: (i) a first position in which the valve redirects coolant flow from the parallel channel to the transverse channel; (ii) a second position in which the valve allows coolant flow in the parallel channel and blocks coolant flow in the transverse channel; and (iii) a third position in which the valve blocks coolant flow in both the parallel channel and the transverse channel.

[0013] In some embodiments, the method may further include moving the valve from one of the first, second, and third positions to another of the first, second, and third positions to alter the coolant flow through the cooling plate.

[0014] In some embodiments, the method may further include adjusting the position of the valve to change the coolant flow through the cooling plate.

[0015] In some embodiments, the position of the valve can be automatically adjusted in response to the thermal conditions of the cooling plate.

[0016] According to another aspect of this disclosure, the cooling plate assembly may include a base plate defining an inlet channel, an outlet channel, a first intermediate channel, a second intermediate channel, and a transverse channel. The first and second intermediate channels may be respectively disposed between the inlet and outlet channels, and the transverse channel may be arranged to intersect the first intermediate channel to define a first intersection point and to intersect the second intermediate channel to define a second intersection point. The cooling plate assembly may also include a valve comprising at least one protrusion. Within the transverse channel, the valve may be movable between at least two of the following: (i) a first position, in which at least one protrusion is disposed relative to the first and second intersection points to redirect coolant flow from the first intermediate channel to the second intermediate channel; (ii) a second position, in which at least one protrusion is disposed relative to the first intersection point to guide coolant flow along the first intermediate channel past the first intersection point; and (iii) a third position, in which at least one protrusion is disposed relative to the first intersection point to isolate at least a segment of the first intermediate channel from the coolant flow.

[0017] In some embodiments, the valve may be movable within a lateral passage between any two of the first, second, and third positions.

[0018] In some embodiments, the valve may be a rotary valve that is rotatable within a lateral passage between a first position, a second position, and a third position.

[0019] In some embodiments, at least one protrusion of the valve may be positioned relative to the second intersection to guide coolant flow along the second intermediate channel through the second intersection when the valve is in the second position.

[0020] In some embodiments, at least one protrusion of the valve may be positioned relative to the second intersection point to isolate at least a segment of the second intermediate passage from the coolant flow when the valve is in the third position.

[0021] In some embodiments, the valve may include a first end and a second end, the second end being coupled to the first end via a connecting rod disposed in one of an inlet passage and an outlet passage. At least one protrusion may be provided on the second end.

[0022] In some embodiments, the transverse channel may be a first transverse channel, and the valve may be a first valve. The base plate may further define a second transverse channel spaced apart from the first transverse channel, the second transverse channel being arranged to intersect the first intermediate channel to define a third intersection point, and intersect the second intermediate channel to define a fourth intersection point. The cooling plate assembly may also include a second valve, the second valve including at least one protrusion. The second valve may be movable independently of the first valve. The second valve may be movable within the second transverse channel between at least two of the following: (i) a first position, in which at least one protrusion is positioned relative to the third and fourth intersection points to redirect coolant flow from the first intermediate channel to the second intermediate channel; (ii) a second position, in which at least one protrusion is positioned relative to the third intersection point to guide coolant flow along the third intermediate channel past the first intersection point; and (iii) a third position, in which at least one protrusion is positioned relative to the third intersection point to isolate at least a segment of the first intermediate channel from the coolant flow.

[0023] In some embodiments, the valve may be a first valve, and the base plate may further define a third intermediate channel and a fourth intermediate channel. The transverse channel may be arranged to also intersect the third intermediate channel to define a third intersection point, and to intersect the fourth intermediate channel to define a fourth intersection point. The cooling plate assembly may also include a second valve, the second valve including at least one protrusion. The second valve may abut against the first valve when the first valve and the second valve are disposed in the transverse channel. The second valve may be movable independently of the first valve. The second valve may be movable within the transverse channel between at least two of the following: (i) a first position, in which at least one protrusion is disposed relative to the third and fourth intersection points to redirect coolant flow from the third intermediate channel to the fourth intermediate channel; (ii) a second position, in which at least one protrusion is disposed relative to the third intersection point to guide coolant flow along the third intermediate channel past the third intersection point; and (iii) a third position, in which at least one protrusion is disposed relative to the third intersection point to isolate at least a segment of the third intermediate channel from the coolant flow.

[0024] In some embodiments, the inlet channel and the outlet channel may extend along opposite sides of the base plate. A first intermediate channel and a second intermediate channel may extend parallel to the inlet channel and the outlet channel. A transverse channel may be configured perpendicular to the inlet channel, the outlet channel, and the intermediate channels.

[0025] According to another aspect of this disclosure, the cooling plate assembly may include an extrusion base plate defining a plurality of extrusion channels. The plurality of extrusion channels may include: an inlet channel configured to deliver coolant to the base plate; an outlet channel configured to discharge coolant from the base plate; and at least two intermediate channels positioned between the inlet channel and the outlet channel. Transverse channels machined in the extrusion base plate may intersect the inlet channel, the at least two intermediate channels, and the outlet channel to connect and transfer coolant between the inlet channel, the at least two intermediate channels, and the outlet channel.

[0026] In some embodiments, the transverse channel may be a first milled transverse channel, and the base plate may also include a second milled transverse channel. Each of the first and second milled transverse channels may be arranged to intersect with an inlet channel, at least two intermediate channels, and an outlet channel. The first and second milled transverse channels may be arranged around opposite ends of the base plate.

[0027] In some embodiments, the cooling plate assembly may further include a first valve disposed in a first milling transverse channel and a second valve disposed in a second milling transverse channel.

[0028] In some embodiments, within the corresponding milled transverse channel, each of the first and second valves can be moved between at least two of the following: (i) a first position in which at least one protrusion of the valve is arranged to redirect coolant flow between at least two intermediate channels; (ii) a second position in which at least one protrusion is arranged to direct parallel coolant flow through the valve along at least two intermediate channels; and (iii) a third position in which at least one protrusion is arranged to isolate at least a segment of each of the at least two intermediate channels from the coolant flow.

[0029] In some embodiments, each of the at least two intermediate channels may be shaped such that the horizontal cross-sectional dimension of the intermediate channel is greater than the vertical cross-sectional dimension of the intermediate channel.

[0030] In some embodiments, the cooling plate assembly may further include a first valve disposed at a first intersection where the transverse channel intersects with a first intermediate channel of at least two intermediate channels, wherein the first intersection defines a boundary between a first segment and a second segment of the transverse channel. At the first intersection, the first valve is movable between at least two positions: (i) a first position in which a protrusion of the first valve is arranged to redirect coolant flow between the first intermediate channel and the first segment of the transverse channel; (ii) a second position in which a protrusion of the valve is arranged to redirect coolant flow between the first intermediate channel and a second segment of the transverse channel; and (iii) a third position in which a protrusion is arranged to allow coolant flow between the first segment and the second segment of the transverse channel.

[0031] In some embodiments, the first valve may also be configured to allow coolant flow between the first intermediate channel and either the first or second section of the transverse channel when the first valve is in the third position.

[0032] In some embodiments, the cooling plate assembly may further include a second valve disposed at a second intersection point where the transverse channel intersects with a second intermediate channel of at least two intermediate channels, wherein the second intersection point defines a boundary between a second segment and a third segment of the transverse channel. The second valve may be movable within the second intersection point between at least two of the following: (i) a first position in which a protrusion of the second valve is arranged to redirect coolant flow between the second intermediate channel and the second segment of the transverse channel; (ii) a second position in which a protrusion of the valve is arranged to redirect coolant flow between the second intermediate channel and the third segment of the transverse channel; and (iii) a third position in which a protrusion is arranged to allow coolant flow between the second and third segments of the transverse channel.

[0033] In some embodiments, the cooling plate assembly may further include a locking clip configured to engage the surface of the first valve to prevent movement of the first valve between a first position, a second position, and a third position. Attached Figure Description

[0060] While the concept of this disclosure is readily adaptable to various modifications and alternatives, specific embodiments of this disclosure have been illustrated by way of example in the accompanying drawings and will be described in detail herein. However, it should be understood that this disclosure is not intended to limit the concept to the specific forms disclosed, but rather to cover all modifications, equivalents, and alternatives consistent with this disclosure and the appended claims.

[0061] References to "an embodiment," "embodiment," "illustrative embodiment," etc., in this specification indicate that the described embodiment may include a particular feature, structure, or characteristic; however, each embodiment may or may not include that particular feature, structure, or characteristic. Furthermore, these phrases do not necessarily refer to the same embodiment. Additionally, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is believed that implementing that feature, structure, or characteristic in conjunction with other embodiments is within the knowledge of those skilled in the art, whether explicitly described or not.

[0062] In the accompanying drawings, some structural or methodological features may be shown in a specific arrangement and / or order. However, it should be understood that such a specific arrangement and / or order may not be necessary. Instead, in some embodiments, these features may be arranged in a different manner and / or order than those shown in the illustrative drawings. Furthermore, the inclusion of a structural or methodological feature in a particular figure does not imply that this feature is required in all embodiments, and in some embodiments, this feature may be omitted or may be combined with other features.

[0063] This disclosure relates to a thermal management system including a matrix cooling plate, wherein the coolant flow through the cooling plate can be easily configured (and reconfigured) for various applications. As an example, in some cases, the cooling plate flow pattern can be modified by controlling the flow direction and the flow exiting multiple transverse channels, which are drilled perpendicular to the intermediate coolant channels, wherein each transverse channel connects several intermediate channels together. In some embodiments, the transverse channels may be grooves or channels, the openings of which can be sealed by friction welding a sealing plate to the end of the extruder.

[0064] In some embodiments, the opening of the transverse channel can be configured to receive a replaceable plug, which allows flow in the inlet / outlet channel and establishes a serial flow path, such as the single flow path followed by coolant through the cooling plate region. Thus, the replaceable plug can separate the inlet or outlet channel from the parallel flow intermediate channel.

[0065] In some embodiments, the transverse channels can be configured to receive one or more diverter valves. These valves may be valves capable of moving (manually or automatically) between two or more positions, such that changing the valve position alters the flow pattern of the cooling plate. This modification method allows for real-time customization of the cooling plate. Valve features for controlling the flow pattern of the cooling plate include, but are not limited to, minimizing restrictions on flow through the inlet and outlet intermediate channels, allowing valve position adjustment from outside the cooling plate, creating an inlet for water to enter the internal intermediate channel, providing geometry for parallel flow on both sides of the valve, and providing parallel flow geometry on one side of the cooling plate while blocking flow on the other side. In some embodiments, the position of one or more valves can be automatically adjusted in response to the thermal conditions of the matrix cooling plate. As an example, the controller of the thermal management system can determine that different coolant flow patterns should be implemented in the matrix cooling plate and can reposition one or more valves to achieve different coolant flow patterns. These and other features will be described in more detail below with reference to the accompanying drawings of this disclosure.

[0066] Figure 1 An example thermal management system 100 is shown. The thermal management system includes a cooling plate assembly 102 for circulating coolant to remove heat from one or more components disposed adjacent to the cooling plate assembly 102. The cooling plate assembly 102 includes a base plate 104 defining an inlet channel 105 and an outlet channel 106. The inlet channel 105 and the outlet channel 106 extend longitudinally (along the y-axis) along opposite sides of the body of the base plate 104. In one example, the inlet channel 105 receives coolant through an inlet opening 112, while the outlet channel 106 discharges coolant through an outlet opening 114.

[0067] The base plate 104 defines a plurality of intermediate channels 108 disposed between the inlet channel 105 and the outlet channel 106 and arranged to circulate coolant to remove heat from one or more components disposed adjacent to the cooling plate assembly 102. In one example, the intermediate channels 108 extend parallel to each other and are parallel to the inlet channel 105 and the outlet channel 106 along the length of the base plate 104 (longitudinally, or along the y-axis). The intermediate channels 108 may be spaced apart from each other and spaced apart from the inlet channel 105 and the outlet channel 106 along the width of the base plate 104 (laterally, or along the x-axis). In this illustrative embodiment, the intermediate channels 108 are uniformly distributed over the entire area of ​​the base plate 104.

[0068] The intermediate channel 108 of the base plate 104 includes an opening 122 arranged to receive and discharge coolant. A sealing plate 110 may be connected to a first end 124 of the base plate 104, wherein the first end 124 of the base plate 104 is disposed opposite to a second end 126 of the base plate 104. Optionally, the sealing plate 110 may include a sealing plate inlet 116 and an outlet 118, which are aligned with a corresponding one of the inlets 112 and outlets 114 of the base plate 104. In other embodiments, the sealing plate 110 may extend to cover only the opening 122, without covering the inlet opening 112 and the outlet opening 114 of the base plate 104.

[0069] The cross-sectional shape of the intermediate channel 108 of a given cooling plate assembly 102 can be designed to suit the specific purpose of the cooling plate assembly 102. In some cases, a particular application of a given cooling plate assembly 102 can benefit from maximizing heat transfer efficiency by maximizing the surface area (i.e., the perimeter in two dimensions) of the cross-section of the intermediate channel 108 that is in direct contact with the coolant. Examples of such an intermediate channel 108 are shown in the illustrative embodiments.

[0070] The base plate 104 can be near-net-shape extrusion molding using parallel flow holes. In one example embodiment, such as Figure 1 , Figure 2A and Figure 2B In the illustrated embodiment, in addition to the inlet channel 105 and the outlet channel 106, the base plate 104 may also include 12 intermediate channels 108 (or slots). As further described below, the base plate 104 may also be formed (e.g., machined) to include one or more transverse channels connecting the intermediate channels 108 and / or the inlet channel 105 and the outlet channel 106. The transverse channels can connect several sets of parallel flow intermediate channels 108 together. Therefore, as discussed further below, depending on the arrangement of the transverse channels relative to one or more intermediate channels 108 of the base plate 104, a given cooling plate assembly 102 can be configured to provide a high-rate coolant flow or a high coolant residence time.

[0071] Figure 2A Figure 200-A illustrates an example of the coolant flow pattern in cooling plate 102a. The inlet channel 105, outlet channel 106, and intermediate channel 108 of cooling plate 102a are interconnected by a plurality of transverse channels 214 arranged around each of the first end 124 and the second end 126 of base plate 104. In a lateral direction perpendicular to the inlet channel 105 and outlet channel 106 and perpendicular to the intermediate channel 108, the transverse channels 214 extend along a portion of the width (x-axis) of base plate 104.

[0072] exist Figure 2AIn the illustrative embodiment, coolant enters (202) an inlet channel 105 near a first end 124 of the base plate 104. After entering the base plate 104, coolant flow 204 flows from the first end 124 to the second end 126 of the base plate 104. Coolant then enters a first transverse channel 214a near the second end 126 of the base plate 104. The first transverse channel 214a connects the inlet channel 105 and a first subset of intermediate channels 108. In this example, coolant simultaneously or approximately simultaneously enters each intermediate channel of the first subset of intermediate channels 108 via the first transverse channel 214a.

[0073] The first transverse channel 214a guides the coolant flow from the second end 126 (206) to the second transverse channel 214b located at the first end 124 of the base plate 104. The second transverse channel 214b connects the first subset and the second subset of intermediate channels 108. After entering the second transverse channel 214b, the coolant flowing through each intermediate channel 108 in the first subset is guided to the second subset of intermediate channels 108. In this example, the coolant enters each of the second subset of intermediate channels 108 simultaneously or approximately simultaneously via the second transverse channel 214b.

[0074] The second transverse channel 214b guides the coolant flow from the first end 124 208 to the third transverse channel 214c located at the second end 126 of the base plate 104. The third transverse channel 214c connects the second subset of the intermediate channel 108 to the outlet channel 106 of the base plate 104. The third transverse channel 214c guides the coolant flowing through each of the second subsets of the intermediate channel 108 210 to the outlet channel 106 for coolant discharge 212.

[0075] Therefore, the example arrangement of Figure 200-A includes three transverse channels 214 that interconnect the inlet channel 105 and the outlet channel 106 via a central channel 108 to create a four-way cooling plate 102a, wherein two channels have six parallel flow streams. The exemplary arrangement of Figure 200-A can be considered a “high flow” arrangement.

[0076] Figure 2B Example Figure 200-B illustrates the coolant flow pattern in cooling plate 102b. The inlet channel 105, outlet channel 106, and intermediate channel 108 of cooling plate 102b are interconnected by a plurality of transverse channels 236 arranged around each of the first end 124 and the second end 126 of base plate 104. In a lateral direction perpendicular to the inlet channel 105 and outlet channel 106 and perpendicular to the intermediate channel 108, the transverse channels 236 extend along a portion of the width (x-axis) of base plate 104.

[0077] exist Figure 2BIn the illustrative embodiment, coolant enters (220) the base plate 104 at an inlet channel 105 near the first end 124 and exits (234) the base plate 104 at an outlet channel 106 near the first end 124. Upon entering the base plate 104, the coolant flows (222) along the inlet channel 105 to a first transverse channel 236a, which connects the inlet channel 105 and a first subset of the intermediate channel 108. The first subset of the intermediate channel 108 guides (224) coolant to the second subset of the intermediate channel 108 via a second transverse channel 236b connecting the first subset and the second subset of the intermediate channel 108. Similarly, the second subset of the intermediate channel 108 guides (226) coolant from the second subset to the third subset of the intermediate channel 108 via a third transverse channel 236c. Furthermore, the third subset of intermediate channel 108 directs coolant (228) to the fourth subset of intermediate channel 108 via the fourth transverse channel 236d. The fifth transverse channel 236e receives (230) coolant from each of the fourth subsets of intermediate channel 108 and then directs the flow 232 to the outlet channel 106, where the coolant exits 234 from the base plate 104.

[0078] Therefore, the example arrangement of Figure 200-B includes five transverse channels 236, which connect the inlet channel 105 and the outlet channel 106 via intermediate channels 108 to create a six-way cooling plate 102b. When applied to a twelve-intermediate-channel base plate 104, the arrangement of Figure 200-B includes four subsets of intermediate channels 108 with parallel flow, where each subset includes three intermediate channels 108. The larger number of subsets of intermediate channels 108 and transverse channels 236 increases the amount of time (also referred to as “residence time”) that the coolant spends within the cooling plate 102b. Residence time can be measured, for example, as the time interval between, for example, the first time when the coolant enters the cooling plate 102b at 220 and the second time when the coolant leaves the cooling plate 102b at 234. Therefore, the residence time of the coolant in the example arrangement of Figure 200-B can be greater than the residence time of the coolant in the example arrangement of Figure 200-A.

[0079] Figure 3 A plug 300 configured to regulate coolant flow in a cooling plate assembly 102 is shown. The plug 300 may include a first end (head) 302 and a second end 304 connected to each other by a connecting rod (shaft) 306. In one example, the connecting rod 306 may extend longitudinally from the center of the inner side 308 of the second end 304 to the center of the inner side 310 of the first end 302. As shown, as an example, in Figure 4 In this configuration, the plug 300 can be configured to be disposed within the transverse channel 402 of the base plate 104 to guide the flow of coolant.

[0080] The outer side 312 of the first end portion 302 is disposed opposite to the inner side 310 of the first end portion 302 and includes a drive groove 314. The drive groove 314 is configured to receive a portion of a tool, such as the tip of a screwdriver, during insertion of the plug 300 into the lateral channel. In one example embodiment, the first end portion 302 defines a sealing groove 316 disposed around the body 320 of the first end portion 302 and extending between the inner side 310 and the outer side 312. The sealing groove 316 may be configured to receive a seal 318.

[0081] Figure 4 An example arrangement 400 for a cooling plate assembly 102 is shown, including a transverse channel 402. In the illustrative embodiment, the transverse channel 402 extends laterally about a first end 124 along the width (x-axis) of the base plate 104 relative to the inlet channel 105, the outlet channel 106, and the intermediate channel 108. Figure 4 As shown, the transverse channel 402 extends all the way to the first side 404 of the base plate 104 to define an opening 406 therein. Although Figure 4 The transverse channel 402 shown extends from the first side 404 of the base plate 104, but the design is not limited thereto. (See at least...) Figure 7A and Figure 8A As described, the transverse channel 402 of the base plate 104 may extend between one or more of a first side 404 and a second side (not shown) of the base plate 104, with the second side disposed opposite to the first side 404. The transverse channel 402 may intersect any number of inlet channels 105 and outlet channels 106 and intermediate channels 108 (e.g., the transverse channel 402 may intersect only one of the inlet channels 105 and outlet channels 106, and only a subset of the intermediate channels 108).

[0082] The transverse channel 402 can be configured to receive the plug 300. In one example embodiment, the first end 302 of the plug 300 (with or without a seal 318) can be sized to seal the transverse channel opening 406 around a first side 404 of the base plate 104 to prevent fluid flow therethrough. The second end 304 of the plug 300 can be sized to seal a first transverse channel portion 407 of the transverse channel 402, which extends between the inner wall 409 of the inlet channel 105 and the outer wall 411 of the intermediate channel 108 adjacent to the inlet channel 105. Figure 4 In the illustrated embodiment shown, the body 320 of the first end 302 is sized such that the outer side 312 of the first end 302 is flush with the first side 404 of the base plate 104, and the inner surface 310 of the first end 302 is flush with the outer wall 413 of the inlet channel 105.

[0083] Coolant can enter inlet channel 105 408 through connector fitting 405, which is configured to connect cooling plate assembly 102 to one or more other components (not shown) of thermal management system 100, such as, but not limited to, coolant pumps, water pumps, heat exchangers, and cooling towers. When plug 300 is arranged within transverse channel 402, connecting rod 306 of plug 300 extends across the width (x-axis) of inlet channel 105 from outer wall 413 to inner wall 409. First end 302 of plug 300 prevents coolant from flowing between outer wall 413 of inlet channel 105 and a first side of base plate 104. Similarly, second end 304 of plug 300 prevents coolant from flowing between inner wall 409 of inlet channel 105 and outer wall 411 of intermediate channel 108 adjacent to inlet channel 105. Coolant can then pass through intermediate channel 108 410, 412, which has parallel flow. The second end 304 of the plug 300 prevents the flow of coolant from the intermediate channel 108 into the inlet channel 105. As discussed further below, additional components can be used to redirect the flow of coolant in the intermediate channel 108.

[0084] Figure 5 An isometric projection view 500 is shown for a valve 502 used to control the flow of coolant through a cooling plate assembly 102. While valve 502 is illustratively represented as a rotary valve, it is contemplated that valve 502 may alternatively be represented as a valve actuated by linear movement or a combination of rotary and linear movement. Valve 502 includes a first end 504 and a second end 506 connected to each other by a connecting rod 508. In this illustrative embodiment, the first end 504 of valve 502 is compared with a reference... Figure 3 and Figure 4 The first end 302 of the described plug 300 is substantially similar.

[0085] The second end 506 of valve 502 includes a protrusion in the form of an elongated ridge member 510 having a first ridge side 512 and a second ridge side 514, wherein the second ridge side 514 is disposed opposite to the first ridge side 512. Each of the first ridge side 512 and the second ridge side 514 defines a plurality of additional protrusions, such as blocking members 516 (516a, 516b, 516c) and / or parallel flow members 522.

[0086] exist Figure 5In the illustrative embodiment of the valve 502 shown, a first ridge side 512 of the second end 506 defines a first blocking member 516a and a second blocking member 516b. The first blocking member 516a surrounds a first end 518 of an elongated ridge member 510, and the second blocking member 516b surrounds a second end 520 of the elongated ridge member 510, wherein the second end 520 of the elongated ridge member 510 is disposed opposite to the first end 518 of the elongated ridge member 510. A second ridge side 514 defines a third blocking member 516c, which is disposed around the center of the second ridge side 514 of the elongated ridge member 510. Each blocking member 516 is exemplary formed as a semi-circular protrusion and has a flat side and an arcuate side, the flat side being connected to one of the first ridge side 512 and the second ridge side 514, and the arcuate side extending outward from the respective ridge side 512, 514. The blocking member 516 can be shaped such that when the valve 502 is disposed within the transverse channel 402 of the base plate 104, the blocking member 516 regulates the flow through the intermediate channel 108 and the transverse channel 402 by selectively completing a portion of the geometry of the intermediate channel 108 and / or the transverse channel 402. Those skilled in the art will understand that... Figure 5 The number and positioning of the blocking members 516 shown are merely exemplary, and other embodiments of the valve 502 may use other numbers and / or positioning of the blocking members 516.

[0087] exist Figure 5 In the illustrative embodiment of the valve 502 shown, a plurality of parallel flow members 522 extend along the bottom 524 (opposite to the top 526) of the elongated ridge member 510 in a manner perpendicular to the elongated ridge member 510. Therefore, each of the parallel flow members 522 and the elongated ridge member 510 defines a T-shaped cross-section (in... Figure 7C (This can be seen most clearly in the image). The parallel flow member 522 can be shaped such that when the valve 502 is disposed within the transverse channel 402 of the base plate 104, the parallel flow member 522 regulates the flow through the intermediate channel 108 and the transverse channel 402 by selectively completing a portion of the geometry of the intermediate channel 108 and / or the transverse channel 402. Those skilled in the art will understand that... Figure 5 The number and positioning of the parallel flow members 522 shown are merely exemplary, and other embodiments of the valve 502 may use other numbers and / or positioning of the parallel flow members 522.

[0088] Figure 6 yes Figure 5 A simplified diagram 600 shows the valve 502 positioned within the cooling plate assembly 102. The base plate 104 includes a transverse channel 602, as shown in the reference above. Figure 4Similar to the discussed lateral passage 402, lateral passage 602 extends laterally relative to the entrance passage 105 and the intermediate passages 108 (including intermediate passages 108a, 108b, 108c, 108d, 108e, 108f, 108g). Lateral passage 602 intersects with the entrance passage 105 and the intermediate passages 108 to define a series of intersections. Lateral passage 602 defines opening 606, and lateral passage 602 intersects with one side of the base plate 104 at opening 606. Figure 6 As shown, the transverse passage 602 is arranged to receive valve 502 such that the first end 504 of valve 502 seals opening 606 to prevent coolant from flowing through opening 606. A connecting rod 508, which engages with the first end 504 and the second end 506 of valve 502, extends across the width of inlet passage 105 to allow coolant to flow through inlet passage 105.

[0089] When valve 502 is Figure 6 When positioned in the transverse channel 602, each parallel flow member 522 is aligned with one of the intermediate channels 108a, 108b, 108c, 108d, 108e, 108f. Specifically, each parallel flow member 522 is positioned at the intersection of the transverse channel 602 and one of the intermediate channels 108a, 108b, 108c, 108d, 108e, 108f. When valve 502 is in position... Figure 6 When the valve 502 is positioned in the transverse channel 602, the first blocking member 516a of the valve 502 is positioned in the portion of the transverse channel 602 located between the inlet channel 105 and the intermediate channel 108a, the second blocking member 516b of the valve 502 is positioned in the portion of the transverse channel 602 located between the intermediate channels 108f and 108g, and the third blocking member 516c of the valve 502 is positioned in the portion of the transverse channel 602 located between the intermediate channels 108c and 108d. As described above, it should be understood that... Figure 6 The number and positioning of the intermediate channels 108, as well as the blocking members 516 and parallel flow members 522 shown, are illustrative only; other specific configurations may also be used. (As will be discussed below regarding...) Figures 7A to 7C , Figures 8A to 8C and Figures 11A to 11C In more detail, within the transverse channel 602, the valve 502 can rotate between several different orientations to selectively redirect the coolant flow in the base plate 104.

[0090] Figure 7AAn exemplary arrangement 700-A of multiple valves 502 (502a, 502b, 502c, 502d) is shown, these valves being positioned within a portion of a base plate 104 to control the flow of coolant through the base plate 104. Each valve in the 502 has a design similar to that referenced above. Figure 5 A similar structure is described. As mentioned above, the base plate 104 defines an inlet channel 105, an outlet channel 106, and a plurality of intermediate channels 108 between the inlet channel 105 and the outlet channel 106. Figure 7A In the illustrative embodiment, the base plate 104 is further defined to support the transverse channels 702, 704 (as referenced). Figure 4 and Figure 6 (The description of transverse channels 402 and 602 is similar). Valve 502a is located at one end of transverse channel 702, and valve 502c is located at the other end of transverse channel 702, such that the corresponding second ends of valves 502a and 502c abut against each other. Valve 502b is located at one end of transverse channel 704, and valve 502d is located at the other end of transverse channel 704, such that the corresponding second ends of valves 502b and 502d abut against each other.

[0091] exist Figures 7A to 7C In the middle, each valve in valve 502 is arranged in a first position, in which the parallel flow member 522 is oriented away from the intermediate channel 108. Figure 7B A bottom view 700-B (viewed from the bottom 742 of the base plate 104) shows a valve 502a positioned in the first location. The valve 502a includes a connecting rod 508 extending across the inlet passage 105 to allow unobstructed flow of coolant through the inlet passage 105. The connecting rod 508 connects a first end 504 and a second end 506. As discussed further below, an elongated ridge member 510, a first blocking member 516a and a second blocking member 516b disposed on the first ridge side 512, and a third blocking member 516c disposed on the second ridge side 514 redirect the coolant flow through the base plate 104.

[0092] Reference Figure 7A The connecting rod 508 of the first valve 502a allows coolant to flow through the inlet passage 105. While the first blocking member 516a of the first valve 502a prevents coolant from entering the first transverse passage 702 near the first ridge side 512, coolant flows into the first transverse passage 702 near the second ridge side 514 of the first valve 502a. The third blocking member 516c of the first valve 502a guides the coolant through a first subset of the intermediate passage 108 and towards the second transverse passage 704.

[0093] When the coolant reaches the second transverse channel 704, the first blocking member 516a of the second valve 502b guides the coolant along the first ridge side 512 of the second valve 502b and toward the second subset 108 of the intermediate channel. Then, the second blocking member 516b of the second valve 502b guides the coolant to flow through the second subset of the intermediate channel 108 and back toward the first transverse channel 702.

[0094] When the coolant returns to the first transverse channel 702, the third blocking member 516c of the first valve 502a guides the coolant along the second ridge side 514 of the first valve 502a, along the second ridge side 514 of the third valve 502c, and toward the third subset of the intermediate channel 108. Then, the third blocking member 516c of the third valve 502c guides the coolant to flow through the third subset of the intermediate channel 108 and return to the second transverse channel 704.

[0095] When the coolant returns to the second transverse channel 704, the second blocking member 516b of the fourth valve 502d guides the coolant along the first ridge side 512 of the fourth valve 502d and toward the fourth subset of the intermediate channel 108. Then, the first blocking member 516a of the fourth valve 502d guides the coolant through the fourth subset of the intermediate channel 108 and back to the first transverse channel 702.

[0096] After the coolant returns to the first transverse channel 702, the third blocking member 516c of the third valve 502c guides the coolant along the second ridge side 514 of the third valve 502c and toward the outlet channel 106. The connecting rod 508 of the third valve 502c allows the coolant to flow through the outlet channel 106. The third blocking member 516a of the first valve 502c prevents the coolant from re-entering the first transverse channel 702 along the first ridge side 512 of the third valve 502c.

[0097] Figure 7C Show along Figure 7B A cross-sectional view 700-C, taken along line 7C-7C, shows the cross-section of the first valve 502a. The intermediate channel 108 of the base plate 104 is defined between the first surface 748 and the second surface 740 of the bottom 742 of the base plate 104. (As shown...) Figure 7CAs shown, when the first valve 502a is in the first position, the top 526 of the elongated ridge member 510 abuts against the second surface 740 of the base plate 104, thereby blocking the flow of coolant 744, 746 through the intermediate channels 108. In other words, when the first valve 502a is in the first position, the elongated ridge member 510 prevents (or at least blocks) the flow of coolant from the first ridge side 512 to the second ridge side 514, and vice versa. However, when the first valve 502a is in the first position, coolant is allowed to flow along the first ridge side 512 between the intermediate channels 108 of the base plate 104, at least until the coolant encounters the first blocking member 516a or the second blocking member 516b. Similarly, when the first valve 502a is in the first position, coolant is allowed to flow along the second ridge side 514 between the intermediate channels 108 of the base plate 104, at least until the coolant encounters the third blocking member 516c.

[0098] Figure 8A An exemplary arrangement 800-A of multiple valves 502 (502a, 502b, 502c, 502d) is shown, which are disposed within a portion of a base plate 104 to control the flow of coolant through the base plate 104. Each valve in the 502 has the same characteristics as referenced above. Figure 5 A similar structure is described. As mentioned above, the base plate 104 defines an inlet channel 105, an outlet channel 106, and a plurality of intermediate channels 108 between the inlet channel 105 and the outlet channel 106. Figure 8A In the illustrative embodiment, the base plate 104 is further defined to support the transverse channels 702, 704 (as referenced). Figure 7A (The descriptions of transverse channels 702 and 704 are similar). Valve 502a is located at one end of transverse channel 702, and valve 502c is located at the other end of transverse channel 702, such that the corresponding second ends of valves 502a and 502c abut against each other. Valve 502b is located at one end of transverse channel 704, and valve 502d is located at the other end of transverse channel 704, such that the corresponding second ends of valves 502b and 502d abut against each other.

[0099] exist Figure 8A In arrangement 800-A, the second valve 502b and the fourth valve 502d are arranged in the first position, and their operation is the same as described above. Figure 7A The discussion was conducted in the same way. However, in Figure 8A In this configuration, the first valve 502a and the third valve 502c are arranged in different second positions (see also...). Figure 8B and Figure 8CFor example, by using the tip of a screwdriver inserted into the drive slot of the first end 504 of valve 502, each valve in valve 502 can rotate between multiple different positions (including a first position and a second position) in its respective lateral channels 702, 704. In some embodiments, the first end 504 of each valve 502 and / or the surrounding portion of the base plate 104 may contain markings indicating the position occupied by the respective valve 502.

[0100] When the first valve 502a and the third valve 502c are arranged in the second position, as follows: Figures 8A to 8C As shown, the parallel flow member 522 is disposed in the intermediate channel 108. From Figure 8B and Figure 8C It can be best understood that the orientation of the first valve 502a and the third valve 502c in the second position is relative to that of the first valve 502a and the third valve 502c in... Figure 7B and Figure 7C The orientation of the first position shown is opposite (e.g., rotated 180 degrees). Figure 8B A bottom view 800-B (viewed from the bottom 742 of the base plate 104) shows the valve 502a in the second position. When the valve 502a is in this second position, each of the parallel flow members 522a, 522b, 522c, 522d, 522e, 522f is located within the corresponding one of the intermediate channels 108a, 108b, 108c, 108d, 108e, 108f (see...). Figure 7A Each of the parallel flow components 522a, 522b, 522c, 522d, 522e, and 522f completes the geometry of the corresponding intermediate channels 108a, 108b, 108c, 108d, 108e, and 108f, thereby allowing coolant to flow through each intermediate channel 108, but preventing (or at least blocking) coolant from entering the transverse channel 702 where the first valve 502a is provided.

[0101] Figure 8C Show along Figure 8B The cross-sectional view 800-C, taken along line 8C-8C, shows the cross-section of the first valve 502a. As described above, the intermediate channel 108 of the base plate 104 is defined between the first surface 748 and the second surface 740 of the bottom 742 of the base plate 104. Figure 8CAs shown, when the first valve 502a is in the second position, the parallel flow member 522d completes the first surface 748, forming the top of the intermediate channel 108d, thereby allowing the coolant flow 802 to flow along the intermediate channel 108d. Additionally, the sides of the parallel flow member 522d prevent (or at least block) coolant from flowing from the intermediate channel 108d into the transverse channel 702. Each of the remaining parallel flow members 522a, 522b, 522c, 522e, and 522f of the first valve 502a functions in a similar manner relative to the remaining intermediate channels 108a, 108b, 108c, 108e, and 108f.

[0102] Reference Figure 8A When coolant flowing along intermediate channel 108a encounters first valve 502a arranged in the second position, the coolant passes through the parallel flow member 522a of first valve 502a and continues to flow along the next section of intermediate channel 108a to the second transverse channel 704. Similarly, when coolant flowing along intermediate channel 108b encounters first valve 502a arranged in the second position, the coolant passes through the parallel flow member 522b of first valve 502a and continues to flow along the next section of intermediate channel 108b to the second transverse channel 704. In the same manner, when coolant flowing along intermediate channel 108c encounters first valve 502a arranged in the second position, the coolant passes through the parallel flow member 522c of first valve 502a and continues to flow along the next section of intermediate channel 108c to the second transverse channel 704.

[0103] When the coolant reaches the second transverse channel 704 (from the intermediate channels 108a, 108b, 108c), the first blocking member 516a of the second valve 502b guides the coolant along the first ridge side 512 of the second valve 502b and toward the intermediate channels 108d, 108e, 108f. Then, the second blocking member 516b of the second valve 502b guides the coolant flow through each intermediate channel 108d, 108e, 108f and back to the first valve 502a.

[0104] When coolant flowing along intermediate channel 108d encounters first valve 502a arranged in the second position, the coolant passes through the parallel flow member 522d of first valve 502a and continues to flow along the next section of intermediate channel 108d. Similarly, when coolant flowing along intermediate channel 108e encounters first valve 502a arranged in the second position, the coolant passes through the parallel flow member 522e of first valve 502a and continues to flow along the next section of intermediate channel 108e. In the same manner, when coolant flowing along intermediate channel 108f encounters first valve 502a arranged in the second position, the coolant passes through the parallel flow member 522f of first valve 502a and continues to flow along the next section of intermediate channel 108f.

[0105] Figure 9 An example arrangement 900 of the cooling plate assembly 102 is shown, wherein eight valves 904a-904h are arranged in pairs in each of the four transverse channels 906a-906d of the base plate 902. Each of the eight valves 904a-904h can be moved between multiple positions (including the first and second positions described above) to configure the cooling plate assembly 102 for various applications. Although Figure 9 The illustrated device 900 has four transverse channels 906 and eight valves 904, but it is conceivable that any number of transverse channels and valves can be used. For example, in some embodiments, the base plate may include eight or sixteen transverse channels, configured to receive 16 or 32 valves, respectively.

[0106] Figure 10A and Figure 10B Two example flow paths 1000-A and 1000-B are shown for a cooling plate 1002 configured to cool component 1004. Using valves of the type described above, the cooling plate 1002 can be easily varied between flow paths 1000-A and 1000-B by changing the positions of certain valves. As discussed further below, varying the cooling plate 1002 between flow paths 1000-A and 1000-B can change the preheating area parameter, which indicates the area of ​​the coolant from inlet channel 1008 that travels within the cooling plate 1002 before reaching component 1004.

[0107] The cooling plate 1002 includes a first transverse channel 1006a, which extends along the x-axis around a first end 1012 of the cooling plate 1002 between the inlet channel 1008 and the outlet channel 1010. The cooling plate 1002 also includes a second transverse channel 1006b, which extends along the x-axis around a second end 1014 of the cooling plate 1002 between the inlet channel 1008 and the outlet channel 1010. The cooling plate 1002 also includes a third transverse channel 1006c and a fourth transverse channel 1006d, which are respectively located at intermediate positions between the first end 1012 and the second end 1014 of the cooling plate 1002, extending along the x-axis between the inlet channel 1008 and the outlet channel 1010. Similar to the cooling plate discussed above, this cooling plate includes multiple intermediate channels 1016. These intermediate channels 1016 extend parallel to the inlet channel 1008 and the outlet channel 1010, and intersect with the first transverse channel 1006a, the second transverse channel 1006b, the third transverse channel 1006c, and the fourth transverse channel 1006d. Each of the first transverse channel 1006a, the second transverse channel 1006b, the third transverse channel 1006c, and the fourth transverse channel 1006d is equipped with a pair of valves, whose operation is similar to that described above. Figures 5 to 8C The methods discussed are similar.

[0108] In order to achieve Figure 10A In the flow path 1000-A shown, the valves in the transverse channel 1006a and transverse channel 1006b are respectively oriented in the first position (refer to above). Figures 7A-7C (Description), while the valves in transverse channel 1006c and transverse channel 1006d are respectively oriented in the second position (refer to above). Figures 8A to 8C (Description). Therefore, the coolant is laterally redirected in the transverse channels 1006a, 1006b by the valves arranged in the first position. However, the coolant does not travel in the transverse channels 1006c, 1006d, but continues to flow along the corresponding intermediate channel 1016, as guided by the valves arranged in the second position. When traveling along flow path 1006-A, as... Figure 10A As shown, the coolant travels over approximately 85% of the total area of ​​the cooling plate 1002 and collects heat before reaching component 1004.

[0109] In order to achieve Figure 10B In the flow path 1000-B shown, the valves in the transverse channel 1006c and transverse channel 1006d are respectively redirected to the first position (see above). Figures 7A-7C(Description), while the valves in transverse channel 1006a and transverse channel 1006b remain oriented in the first position. Thus, in each of the transverse channels 1006a, 1006b, 1006c, and 1006d, at least a portion of the coolant is laterally redirected via the valves arranged in the first position. As the coolant travels along flow path 1006-B, as... Figure 10B As shown, before reaching component 1004, this portion of coolant travels through only about 20% of the total area of ​​cooling plate 1002 and collects heat. In some embodiments, as described above, valves in transverse channel 1006c and transverse channel 1006d are redirected by the user manually changing the flow path between flow paths 1000-A and 1000-B. In other embodiments, valves in transverse channels 1006c and 1006d are automatically redirected (e.g., via controllers and electric actuators) in response to thermal conditions of the matrix cooling plate.

[0110] See now Figure 11A and Figure 11B The figure shows a top view 1100-A and a side cross-sectional view 1100-B of a valve 502 located at a third position within the transverse channel 702 of the base plate 104. The structure of this valve 502 is similar to that described above. Figure 5 Similar to the description. When arranged in the third position, the first side 528 of each parallel flow member 522 of valve 502 is disposed in the intermediate channel 108 corresponding to that parallel flow member 522, while the second side 530 of each parallel flow member 522 of valve 502 is disposed outside the intermediate channel 108 corresponding to that parallel flow member 522 (in Figure 11B (Best visible in the cross-section). In this position, each parallel flow member in the parallel flow member 522 covers the portion of the corresponding intermediate channel 108 facing that parallel flow member 522. In this way, each parallel flow member in the parallel flow member 522 prevents (or at least blocks) the coolant flow 746 approaching the valve 502 from the first side from entering the transverse channel 702 or continuing along the intermediate channel 108 (when the valve is in...). Figure 11B (As shown in the third position). Simultaneously, the coolant flow 744 approaching valve 502 from the second side (opposite to the first side) is redirected from the intermediate channel 108 along the second ridge side 514 of valve 502 and along the transverse channel 702 (thus, when valve 502 is in the first or third position, Figure 7C and Figure 11B The coolant flow 744 shown operates in a similar manner.

[0111] See now Figure 11C The figure shows a side cross-sectional view 1100-C of a valve in a fourth position located within a transverse channel 702 of the base plate 104. (As can be seen by comparison...) Figures 11C-11BIt will be understood that the fourth position of valve 502 is a "mirror image" of the third position, which is flipped along the z-axis direction of the cooling plate assembly 102. When the valve is arranged in the fourth position, as... Figure 11C As shown, the second side 530 of each parallel flow member 522 of valve 502 is disposed in the intermediate channel 108 corresponding to that parallel flow member 522, while the first side 528 of each parallel flow member 522 of valve 502 is disposed outside the intermediate channel 108 corresponding to that parallel flow member 522. In this fourth position (similar to the third position), each parallel flow member 522 covers the portion of the corresponding intermediate channel 108 facing that parallel flow member 522. Thus, when valve 502 is in the fourth position, each parallel flow member 522 prevents (or at least blocks) the coolant flow 744 approaching valve 502 from the second side from entering the transverse channel 702 or continuing along the intermediate channel 108. At the same time, the coolant flow 746 approaching valve 502 from the first side is redirected from the intermediate channel 108 along the first ridge side 512 of valve 502 and along the transverse channel 702 (thus, when valve 502 is in the first or fourth position, Figure 7C and Figure 11C The coolant flow 746 shown operates in a similar manner.

[0112] Figures 12A to 12D Four exemplary flow paths 1200-A, 1200-B, 1200-C, and 1200-D are shown for use with the illustrative cooling plate 1002. (Refer to above) Figures 10A to 10B The structure of the illustrative cooling plate 1002 is described. Using valves of the type described above, the cooling plate 1002 can be easily varied between any flow paths in flow paths 1200-A, 1200-B, 1200-C, and 1200-D by changing the positions of certain valves. As described above, manual and automatic valve repositioning is conceivable to achieve various parallel flow, serial flow, and / or obstructed flow regions (and thus to achieve various flow paths 1200-A, 1200-B, 1200-C, and 1200-D).

[0113] With regard to the above discussion Figure 10B similar, Figure 12A The flow path 1200-A of the cooling plate 1002 is shown, wherein all valves (located in each of the transverse channels 1006a, 1006b, 1006c, 1006d) are arranged in a first position (see above). Figures 7A to 7C(As described). When the valves provided in the transverse channels 1006a and 1006c are respectively arranged in the first position, a first coolant flow region 1212 of the cooling plate 1002 is defined between the transverse channels 1006a and 1006c. Similarly, when the valves provided in the transverse channels 1006c and 1006d are respectively arranged in the first position, a second coolant flow region 1214 of the cooling plate 1002 is defined between the transverse channels 1006c and 1006d. Likewise, when the valves provided in the transverse channels 1006b and 1006d are respectively arranged in the first position, a third coolant flow region 1216 of the cooling plate 1002 is defined between the transverse channels 1006b and 1006d. In one example, each of the coolant flow regions 1212, 1214, and 1216 provides a degree of independent thermal management for one or more components (not shown) located adjacent to the corresponding flow region. Therefore, the temperature of the coolant circulating in each of the flow regions 1212, 1214, and 1216 is largely unaffected by temperature changes in other flow regions.

[0114] Figure 12B Showing with Figure 12A The flow path 1200-B of the cooling plate 1002 is similar, but the valve in the transverse channel 1006d is arranged in a second position (see above). Figures 8A to 8C (As described). Thus, in flow path 1200-B, coolant flow is prevented (or largely blocked) along the transverse channel 1006d, but coolant flows along the intermediate channel 1008 between the through channels 1006b and 1006c. In fact, refer to... Figure 12A The discussed flow regions 1214 and 1216 are joined together to form a new, larger flow region 1218 defined between the transverse channels 1006b and 1006c. As described above, flow region 1218 can operate to a certain extent independently of flow region 1212, such that the temperature of the coolant circulating in each flow region 1212, 1218 is largely unaffected by temperature changes in the other flow region.

[0115] Figure 12C Showing with Figure 12A The flow path 1200-C of the cooling plate 1002 is similar, but the valve in the transverse channel 1006c is arranged in a second position (see above). Figure 8A -C as described. Thus, in flow path 1200-C, coolant flow is prevented (or largely blocked) along the transverse channel 1006c, but coolant flows along the intermediate channel 1008 between the through channels 1006a and 1006c. In fact, refer to... Figure 12AThe discussed flow regions 1212 and 1214 are joined together to form a new, larger flow region 1220 defined between the transverse channels 1006a and 1006d. As described above, flow region 1220 can operate to a certain extent independently of flow region 1216, such that the temperature of the coolant circulating in each flow region of flow regions 1216 and 1220 is largely unaffected by temperature changes in the other flow region.

[0116] Figure 12D Showing with Figure 12A The flow path 1200-D of the cooling plate 1002 is similar, but the valves in the transverse passages 1006c and 1006d are arranged in the second position (see above). Figure 8A -C as described). In this way, in flow path 1200-D, the flow of coolant along the transverse channels 1006c, 1006d is prevented (or largely blocked), but the coolant flows along the intermediate channel 1008 between the through channels 1006a and 1006b. In fact, refer to... Figure 12A The three flow regions 1212, 1214, and 1216 discussed are all joined together to form a new, larger flow region 1222 defined between the transverse channels 1006a and 1006b. In this way, flow path 1200-D is connected to the above-mentioned reference... Figure 10A The flow path 1000-A discussed is similar.

[0117] By moving one or more valves of the cooling plate 1002 to the above reference Figure 11A The third and / or fourth positions described in -C can form additional exemplary flow paths for the cooling plate 1002. As an example, refer to... Figure 12A and 12C The diagram shows that if the valve located in the transverse channel 1006d is arranged in... Figure 11C The fourth position shown (instead of) Figure 7A In the first position of -C), the valve located in the transverse channel 1006d will block the flow of coolant into the portion of the intermediate channel 1008 extending between the transverse channels 1006b and 1006d, thereby converting region 1216 into a "dry region" without coolant flow (while allowing flow regions 1212, 1214, and 1220 to operate as described above). See also... Figure 12A If the valve located in the transverse channel 1006d is arranged in Figures 11A to 11B The third position shown, while the valve arranged in the transverse channel 1006c is located in Figure 11CIn the fourth position shown, these valves will block the flow of coolant into the portion of the intermediate channel 1008 extending between the transverse channels 1006c and 1006d, thereby transforming region 1214 into a "dry region" without coolant flow (while allowing flow regions 1212 and 1216 to operate as described above). Those skilled in the art will understand that the above configuration is merely exemplary and illustrative in nature, and many other configurations and flow paths can be implemented using the matrix cooling plate of this disclosure.

[0118] Figures 13A to 13B Isometric views 1300-A and 1300-B, respectively, of another illustrative embodiment of valve 1302, are shown. Valve 1302 defines a body 1316 having, for example, a cylindrical shape. A drive groove 1318 defined in the proximal end 1304 of the body 1316 is configured to receive part of a hand tool (not shown), allowing valve 1302 to be reoriented relative to the base plate 1400 of the cooling plate assembly. The distal end portion 1306 of the body 1316 includes a plurality of protrusions, including a central ridge 1310, a first rim 1312a, and a second rim 1312b. A first recess 1308a and a second recess 1308b are defined in the distal end portion 1306 of the body 1316 and are located on either side of the central ridge 1310. Figures 13A to 13B In the illustrative embodiment, the first recess 1308a is defined between the central ridge 1310 and the first rim 1312a, while the second recess 1308b is defined by the central ridge 1310 and the second rim 1312b.

[0119] Figure 14 A cooling plate assembly including valve 1302 is shown, which controls the flow of coolant within a base plate 1400. The base plate 1400 defines a first intermediate channel 1402 and a second intermediate channel 1404 that extend longitudinally and are arranged adjacent to each other. In one example, the first intermediate channel 1402 extends parallel to the second intermediate channel 1404. In another example, the first intermediate channel 1402 and the second intermediate channel 1404 extend parallel to an outlet channel 1408 and / or an inlet channel (not shown), respectively, which is arranged to discharge or deliver coolant to the base plate 1400.

[0120] exist Figure 14In the illustrative embodiment, valve 1302 is received in a transverse channel 1406, which extends from the top surface 1410 of base plate 1400 toward the bottom of base plate 1400 (but does not reach or pass through the bottom of base plate 1400). The transverse channel 1406 intersects with a first intermediate channel 1402 and a second intermediate channel 1404 defined in base plate 1400. In one example, the transverse channel 1406 is a countersunk opening defining a boss 1414, which is arranged to receive a corresponding lip 1314 disposed around the circumference of the body 1316 of valve 1302. In this illustrative embodiment, the dimensions of the first recess 1308a and the second recess 1308b are respectively designed to correspond to the geometry of the first intermediate channel 1402 and the second intermediate channel 1404. The central ridge 1310 is dimensioned to span the region between the first intermediate channel 1402 and the second intermediate channel 1404. (See at least reference...) Figures 15A to 15C As described in further detail, valve 1302 can move between at least two positions to control the flow of coolant through the first intermediate channel 1402 and the second intermediate channel 1404 and between them.

[0121] Figures 15A to 15C A valve 1302 is shown that can move between multiple positions to control the coolant flow pattern within the base plate 1400. Figure 15A An example configuration 1500-A of the base plate 1400 is shown, including a valve 1302 disposed in a first position within a transverse channel 1406. In this first position, a first recess 1308a of the valve 1302 is longitudinally aligned with the first intermediate channel 1402, and a second recess 1308b of the valve 1302 is aligned with the second intermediate channel 1404. When the valve 1302 is in... Figure 15A In the first position shown, coolant is allowed to flow relatively unobstructed through the first intermediate channel 1402, and similarly, coolant is allowed to flow relatively unobstructed through the second intermediate channel 1404.

[0122] Figure 15B An example configuration 1500-B of the base plate 1400 is shown, including a valve 1302 disposed in a second position within a transverse channel 1406. In this illustrative embodiment, the valve 1302 is rotated 90 degrees within the transverse channel 1406, changing from configuration 1500-A to configuration 1500-B. In the second position, a first recess 1308a extends and interconnects with adjacent portions of the first intermediate channel 1402 and the second intermediate channel 1404, while a second recess 1308b extends and interconnects with other adjacent portions of the first intermediate channel 1402 and the second intermediate channel 1404. When the valve 1302 is in... Figure 15BIn the second position shown, the first recess 1308a redirects coolant from the first intermediate channel 1402 to the second intermediate channel 1404 (or vice versa, depending on the flow direction). Similarly, when valve 1302 is in... Figure 15B In the second position shown, the second recess 1308b redirects the coolant from the second intermediate channel 1404 to the first intermediate channel 1402 (or vice versa, depending on the flow direction).

[0123] Figure 15C An example configuration 1500-C of the base plate 1400 is shown, including a valve 1302 disposed in a third position within a transverse channel 1406. In this illustrative embodiment, the valve 1302 is rotated 45 degrees within the transverse channel 1406, changing from configuration 1500-A or 1500-B to configuration 1500-C. Figure 15C In the third position shown, the first recess 1308a and the second recess 1308b are respectively diagonally (not parallel and not perpendicular) to the first intermediate channel 1402 and the second intermediate channel 1404, such that neither the first recess 1308a nor the second recess 1308b intersects with more than one segment of the first intermediate channel 1402 and the second intermediate channel 1404. Therefore, when the valve 1302 is in the third position, coolant flow is not allowed through the first recess 1308a and the second recess 1308b (or through the first intermediate channel 1402 and the second intermediate channel 1404).

[0124] Figures 16A to 16D A portion of another embodiment of the cooling plate 1602 according to this disclosure is shown. The cooling plate 1602 includes a base plate 1604 constructed similarly to the base plate (e.g., base plate 104) described above. Among other similar features, the base plate 1604 includes an inlet channel 1605, an outlet channel 1606, and a plurality of intermediate channels 1608 disposed between the inlet channel 1605 and the outlet channel 1606 and arranged to circulate coolant to remove heat from one or more components disposed adjacent to the cooling plate assembly 102. In this illustrative example, the intermediate channels 1608 extend parallel to each other and are parallel to the inlet channel 1605 and the outlet channel 1606 along the length of the base plate 1604 (longitudinally, or along the y-axis), and are spaced apart from each other and spaced apart from the inlet channel 1605 and the outlet channel 1606 along the width of the base plate 1604 (transversely, or along the x-axis).

[0125] Similar to the base plate discussed above, base plate 1604 also includes a transverse channel 1610, which intersects and connects at least some intermediate channels 1608 with and is connected to the inlet channel 1605 and outlet channel 1606. As described above, this transverse channel 1610 can be machined (e.g., milled) into an extruded base plate 1604, which includes intermediate channels 1608 as well as inlet channel 1605 and outlet channel 1606. Figure 16A In the illustrated embodiment, one transverse channel 1610 is arranged near the first end 1612 of the base plate 1604, while another transverse channel 1610 is arranged near the second end 1612 of the base plate 1604.

[0126] See now Figure 16B The figure shows a more detailed exploded view of the first end 1612 of the cooling plate 1602. The cooling plate 1602 also includes a plurality of valves 1620. Figure 16B Four such valves (1620a, 1620b, 1620c, and 1620d) were selected. Figures 16A to 16D In the illustrative embodiment, two valves 1620 are provided for each intermediate channel 1608 (one valve 1620 is located at the first end 1612 of the intermediate channel 1608, and the other valve 1620 is located at the second end 1614 of the intermediate channel 1608). For example... Figure 16B As shown, each intermediate channel 1608 has a generally cylindrical hole 1618 at each end 1612, 1614 for receiving a corresponding valve 1620. In this illustrative embodiment, the transverse channel 1610 intersects the cylindrical hole 1618 of each intermediate channel 1608 at one end 1612, 1614.

[0127] See Figures 16C to 16D Each valve 1620 has a generally cylindrical body 1622. A protrusion 1624 extends from the distal end 1626 of the body 1622. In this illustrative embodiment, the protrusion 1624 is formed as a cylindrical wall segment. The valve 1620 may include a washer 1628 located in a circumferential groove of the body 1622 and configured to seal a cylindrical bore 1618 of the base plate 1604 when the valve is disposed in the cylindrical bore 1618. The valve 1620 also includes a head 1630 connected to the proximal end of the body 1622 via a neck 1632. In this illustrative embodiment, the diameter of the neck 1632 is smaller than the diameters of the body 1622 and the head 1630, and includes one or more surfaces configured to engage a locking clip 1640 (see [link to documentation]). Figure 16B(This will be discussed further below). Additionally, in this illustrative embodiment, the head 1630 includes a drive groove 1634 configured to receive a portion of a tool, such as the tip of a screwdriver, when the valve 1620 is inserted into the cylindrical bore 1618 or when the cylindrical bore 1618 is adjusted (e.g., rotated).

[0128] See you again Figure 16B Each valve in valve 1620 can be independently adjusted (e.g., rotated) between multiple different positions to regulate the flow characteristics of cooling plate 1602. Figure 16B As shown, valve 1620a is arranged in a first position relative to cooling plate 1602. When valve 1620a is in this first position, protrusion 1624 faces the inlet passage 1605 of cooling plate 1602 and prevents coolant flow between the corresponding intermediate passage 1608 (on which valve 1620 is disposed) and a transverse passage 1610 extending away from the corresponding intermediate passage 1608 toward the inlet passage 1605. However, when in this first position, valve 1620 redirects coolant flow between the corresponding intermediate passage 1608 and the transverse passage 1610 extending away from the corresponding intermediate passage 1608 toward the outlet passage 1606.

[0129] Similarly, Figure 16B As shown, valve 1620d is arranged in a second position relative to cooling plate 1602. When valve 1620d is in this second position, protrusion 1624 faces the outlet channel 1606 of cooling plate 1602 and prevents coolant flow between the corresponding intermediate channel 1608 (where valve 1620 is disposed) and a transverse channel 1610 extending away from the corresponding intermediate channel 1608 toward the outlet channel 1606. However, when in the first position, valve 1620 redirects coolant flow between the corresponding intermediate channel 1608 and the transverse channel 1610 extending away from the corresponding intermediate channel 1608 toward the inlet channel 1605.

[0130] like Figure 16BAs illustrated by valves 1620b and 1620c, valve 1620 can also be moved to a third position. When valve 1620 is in this third position, protrusion 1624 faces the upper surface of base plate 104 and does not obstruct the flow of coolant to any section of transverse channel 1610. In this third position, valve 1620 allows relatively unobstructed coolant flow along transverse channel 1610, and also allows coolant flow between transverse channel 1610 and the corresponding intermediate channel 1608 (where valve 1620 is disposed). Each of the plurality of valves 1620 of cooling plate 1602 can be independently arranged in any of these (and other) positions, thereby providing cooling plate 1602 with a high degree of flexibility and customization for a variety of applications.

[0131] Figures 16A to 16B A locking clip 1640, which can be used with the cooling plate 1602, is also shown for holding each valve 1620 in one of a plurality of predetermined positions. The locking clip 1640 includes a plurality of teeth 1642 configured to be received in corresponding channels 1644 of the base plate 1604. Figure 16B In the illustrative embodiment shown, one such channel is provided between each pair of intermediate channels 1608 (specifically, between adjacent cylindrical holes 1618 of the intermediate channels 1608). When the teeth 1642 of the locking clip 1640 are received in the channel 1644 of the base plate 1604, each tooth 1642 engages at least one surface on the neck 1632 of the associated valve 1620, such that the interference fit between the at least one surface of the neck 1632 and the tooth 1642 prevents (or at least inhibits) the valve 1620 from rotating away from its current position. It is contemplated that any valve described in this disclosure could be provided with a similar position locking mechanism.
