Description

Technical Field

[0001] This invention relates to water-cooled cold plates. Background Technology

[0002] The background technology of this invention relates to cold plates for chipsets.

[0003] As a heat exchanger, the radiator that makes up the cold plate has materials and structures specifically designed for heat conduction and radiation, serving to absorb heat from the heat-generating system and release it to the surroundings. To achieve effective heat dissipation, the radiator is manufactured with a design that maximizes its surface area, thus having multiple fins.

[0004] Heat sinks need to release as much heat as possible through a large surface area, so they can be made of lightweight materials with high thermal conductivity. For this reason, aluminum alloys are most commonly used for heat sinks. Although copper has better thermal conductivity, its weight and cost are much higher than aluminum, so it is not widely used. Sometimes, the parts that directly contact the heat-generating components are made of copper, while the surrounding heatsink / fins are made of aluminum alloy.

[0005] In recent years, with industrial development, highly integrated circuits have been used in the limited space of electrical and electronic devices applied in various fields. This results in the residual energy after electrical energy consumption being converted into heat, generating a large amount of heat. This excessive heat generation can drastically reduce the performance of electrical and electronic equipment or cause malfunctions. Therefore, improving the performance of heat sinks used to dissipate heat to the outside has become an urgent technical challenge.

[0006] On the other hand, as prior art for manufacturing such heat sinks, Korean Patent Publication No. 10-2023-0120838 (hereinafter referred to as the prior art) discloses a technology for manufacturing heat sinks using a scraping process. This scraping process involves cutting the heat sink substrate with a cutting edge and then vertically elevating it to form fins. After each fin is shaped, a cover is placed over it. Inside the sealed interior, flow paths are formed through the gaps between the fins, through which coolant flows to cool the fins.

[0007] The technology disclosed in the aforementioned prior art has the following problems: a manufacturing apparatus can only produce one heat sink at a time, thus hindering mass production. Furthermore, it requires multiple subsequent processes such as molding and coating, leading to complex processes that increase the defect rate or reduce product quality. Additionally, the manufacturing process, which involves vertically standing the fins cut by a cutting edge, makes the fins more prone to bending or contact with adjacent fins, thus limiting their height. In heat sinks, fin height is a key factor in reducing thermal resistance (facilitating heat dissipation), meaning that the technology disclosed in the aforementioned prior art, with its limited fin height, also suffers from limited cooling performance.

[0008] In other words, based on currently available technology, it is impossible to produce multiple heat sinks. The production process consumes a lot of time and money, and due to multiple subsequent processes, there is a risk of product defects, and the heat dissipation performance is inevitably limited.

[0073] Hereinafter, embodiments of the cold plate will be described in detail with reference to the accompanying drawings. In order to clarify the features of the present invention, the following contents are omitted: contents of general techniques disclosed in the prior art and belonging to the art; descriptions of some well-known and obvious constituent elements; contents that can be understood by those skilled in the art even if the specific description is omitted; and related contents that can be fully predicted / derived based on the contents to be described below.

[0074] The cold plate according to the embodiment can be constructed as a water-cooled radiator.

[0075] The structure of the aforementioned cold plate 10 can be as follows: Figure 1 As shown.

[0076] like Figure 1As shown, the aforementioned cold plate 10 is formed in the shape of a plate or a bag and is disposed on the upper part of the object to be cooled 20.

[0077] The object to be cooled 20 may be an electronic circuit element, a semiconductor element, or a computing device such as a CPU or GPU.

[0078] The aforementioned cold plate 10 receives heat generated by the object to be cooled 20 on the upper part of the object to be cooled 20, and the received heat is cooled by a water-cooled radiator formed inside it.

[0079] The aforementioned cold plate 10 includes an inlet 4 formed on one side through which cooling water flows in, an outlet 5 formed on the same side through which cooling water flows out, and a cooling section 6 formed within an internal space through which cooling water flows to achieve heat exchange.

[0080] The aforementioned side can be the opposite side of the side that the object 20 to be cooled is in contact with.

[0081] For example, in Figure 1 In the case shown, the lower surface (-2X surface) of the cold plate 10 is in contact with the surface of the object to be cooled 20, and the upper surface (2X) of the cold plate 10 can become the aforementioned surface.

[0082] The aforementioned face can also be one of the faces with the largest area.

[0083] For example, in Figure 1 In the case shown, either the upper surface (2X) or the lower surface (-2X surface) can be one of the aforementioned surfaces.

[0084] As described above, the cold plate 10 forms the inlet 4 and the outlet 5 on one side, so that when the cooling water flows into the cooling section 6 through the inlet 4, the cooling water flows through the cooling section 6 and exchanges heat with the heat transferred from the object to be cooled 20. After the heat exchange, the cooling water flows out through the outlet 5, thereby achieving the cooling of the heat generated in the object to be cooled 20.

[0085] The structure of the cooling section 6 through which the cooling water flows can be as follows: Figure 2 As shown.

[0086] like Figure 2 As shown, the cooling section 6 includes a side flow path 7 formed along the inner side, a plurality of cooling fins 8 arranged at certain intervals in the area other than the side flow path 7, and a plurality of cooling flow paths 9 formed in each of the certain intervals.

[0087] That is, in the cooling section 6 described above, the plurality of cooling fins 8 can be arranged at certain intervals in the internal region, the plurality of cooling flow paths 9 are formed by the interval between each of the plurality of cooling fins 8, and the side flow paths 7 are formed in the side region other than the region where the plurality of cooling fins 8 are arranged.

[0088] Therefore, the cooling water can flow along the side flow path 7 and the plurality of cooling flow paths 9 inside the cooling section 6.

[0089] Therefore, when the cooling water flows through the plurality of cooling channels 9, that is, between the plurality of cooling fins 8, it comes into contact with the plurality of cooling fins 8, thereby cooling the heat generated from the plurality of cooling fins 8.

[0090] Thus, the cooling section 6 can be configured such that the side flow path 7 and the multiple cooling flow paths 9 are formed by the multiple cooling fins 8, so that the cooling water can circulate.

[0091] On the other hand, when the cooling section 6 is formed with the side flow path 7, the plurality of cooling fins 8 and the plurality of cooling flow paths 9, the cooling fins disposed at the uppermost and lowermost ends of the plurality of cooling fins 8 can be formed as partition fins 8' for dividing the area of ​​the side flow path 7 and the area where the plurality of cooling fins 8 are formed.

[0092] When the cooling section 6 is formed in this structure, the inlet 4 and the outlet 5 can be formed on the above-mentioned side according to the structure of the cooling section 6.

[0093] The aforementioned inlet 4 can be formed at a position corresponding to either the aforementioned side flow path 7 or the central part of the aforementioned cooling section 6.

[0094] That is, the inlet 4 can be formed at either the position corresponding to the area where the side flow path 7 is formed or the position corresponding to the central part of the cooling section 6 is formed on the surface.

[0095] The aforementioned inlet 4 can be formed on either one end or the central side of the aforementioned surface.

[0096] The outlet 5 can be formed at a position corresponding to the side flow path 7.

[0097] That is, the outlet 5 can be formed in the above-mentioned surface at a position corresponding to the area where the side flow path 7 is formed.

[0098] The aforementioned outlet 5 can be formed on one or more of the aforementioned end sides and the other end side.

[0099] The aforementioned inlet 4 and outlet 5 can be formed in different locations.

[0100] For example, if the inlet 4 is formed on one end side, the outlet 5 may be formed on the other end side. If the inlet 4 is formed on the central side, the outlet 5 may be formed on one or more of the one end side and the other end side.

[0101] The aforementioned cold plate 10, including the aforementioned cooling section 6, can be configured as a structure of multiple stacked plates.

[0102] That is, the above-mentioned cold plate 10 can be composed of the above-mentioned multiple plates.

[0103] The shapes of the plurality of plates constituting the cold plate 10 can be as follows: Figure 3 As shown.

[0104] like Figure 3 As shown in (a), (b), and (c), the aforementioned plurality of plates may include a first plate 1 formed in different shapes. Figure 3 (a) of the second board 2 ( Figure 3 (b) and the third board 3 ( Figure 3 (c)).

[0105] The first plate 1 mentioned above may not have holes.

[0106] In the second plate 2 mentioned above, flow path holes 2h can be formed in the area other than the side.

[0107] The aforementioned flow path hole 2h can be a hole that forms a flow path for the cooling water to flow along the first axis 1X when the first plate 1 to the third plate 3 are stacked.

[0108] The aforementioned flow path hole 2h can be a hole formed by the aforementioned plurality of cooling flow paths 9 when the aforementioned first plate 1 to the aforementioned third plate 3 are stacked to form the aforementioned cold plate 10.

[0109] That is, the second plate 2 mentioned above can be a plate that is equivalent to the plurality of cooling flow paths 9 in the cold plate 10 mentioned above.

[0110] The aforementioned third plate 3 may have through holes 3h formed at one or more of its ends and central portion.

[0111] The aforementioned through hole 3h can be a hole that forms a flow path for the cooling water to flow along the third axis 3X when the first plate 1 to the third plate 3 are stacked.

[0112] The aforementioned through hole 3h can be a hole formed by the aforementioned plurality of cooling fins 8 when the aforementioned first plate 1 to the aforementioned third plate 3 are stacked to form the aforementioned cold plate 10.

[0113] That is, the third plate 3 mentioned above can be a plate that is equivalent to the plurality of cooling fins 8 in the cold plate 10 mentioned above.

[0114] Preferably, the third plate 3 may have the through hole 3h formed at one end and at the other end.

[0115] The aforementioned first plate 1, second plate 2, and third plate 3 can be made of the same material.

[0116] The aforementioned first plate 1, the aforementioned second plate 2, and the aforementioned third plate 3 can be made of metal (Cu, Al, STS, tungsten, titanium) or non-metallic (plastic) materials.

[0117] Each of the aforementioned first sheet material 1, the aforementioned second sheet material 2, and the aforementioned third sheet material 3 can be processed through different procedures.

[0118] The first plate 1, the second plate 2, and the third plate 3 mentioned above can be processed to have the same length and width.

[0119] Therefore, when the first plate 1, the second plate 2, and the third plate 3 are stacked, they can be stacked into a shape with horizontal and vertical alignment.

[0120] Each of the aforementioned first plate 1, the aforementioned second plate 2, and the aforementioned third plate 3 can be formed to have a thickness within a reference thickness range.

[0121] The aforementioned reference thickness range can be, for example, 0.05 mm to 5 mm.

[0122] That is, each of the first plate 1, the second plate 2 and the third plate 3 can be formed to have a thickness of 0.05 mm to 5 mm.

[0123] Preferably, at least two of the first plate 1, the second plate 2, and the third plate 3 are formed to have the same thickness.

[0124] Therefore, at least two sheets can be produced from one material.

[0125] Preferably, among the first plate 1, the second plate 2, and the third plate 3, the first plate 1 may be formed with a different thickness than the second plate 2 and the third plate 3.

[0126] In this case, the first plate 1 can be formed to be thicker than the second plate 2 and the third plate 3.

[0127] Therefore, by stacking the first plate 1 to form the uppermost and lowermost ends of the cold plate 10, the frame of the cold plate 10 can be formed to be relatively thick.

[0128] The aforementioned cold plate 10 can be formed by stacking multiple of the aforementioned first plate 1, the aforementioned second plate 2, and the aforementioned third plate 3, each of which are processed into different shapes, in a certain order.

[0129] That is, such as Figure 3 As shown, multiple first plates 1, second plates 2, and third plates 3 of different shapes are processed respectively and stacked in a certain order to form the cold plate 10.

[0130] The stacked structure of the cold plate 10 formed by layering the first plate 1, the second plate 2, and the third plate 3 can be as follows: Figure 4 As shown.

[0131] like Figure 4 As shown, the first plate 1, the second plate 2, and the third plate 3 are stacked in a certain order to form the cold plate 10.

[0132] The aforementioned cold plate 10 can be stacked along the same vertical axis in a manner consistent with the sides of the first plate 1 to the third plate 31.

[0133] In the aforementioned cold plate 10, the first plate 1 to the third plate 31 can be stacked in such a way that the flow path holes 2h of the second plate 2 and the through holes 3h of the third plate 3 are located on the same vertical axis.

[0134] In the aforementioned cold plate 10, the first plate 1 to the third plate 3 can be stacked in the following manner: a first layer of the first plate 1 with one or more stacked layers is arranged at the bottom and top ends, and a second layer of the second plate 2 with one or more stacked layers and a third layer of the third plate 3 with one or more stacked layers are alternately arranged between the bottom and top ends.

[0135] That is, in the above-mentioned cold plate 10, the first plate 1 to the third plate 3 can be stacked in such a way that the first layer is arranged at one or more of the bottom end and the top end, and the second layer and the third layer are arranged alternately between the bottom end and the top end.

[0136] Therefore, the aforementioned cold plate 10 can be configured as a multi-layer structure in which each of the aforementioned first layer, second layer and third layer is configured with a plurality of layers.

[0137] Among them, one or more of the first layers may be stacked with multiple of the first plates 1.

[0138] Furthermore, one or more of the aforementioned third layers may also contain multiple of the aforementioned third-layer plates 3.

[0139] Therefore, in the aforementioned cold plate 10, the thickness (height) of two or more of the aforementioned multiple layers is different from that of the other layers.

[0140] In the aforementioned cold plate 10, multiple first plates 11 may be stacked at one or more of the aforementioned lower end and the aforementioned upper end.

[0141] Therefore, in the aforementioned cold plate 10, one or more of the first layers can be formed to be thicker than the second and third layers.

[0142] In the aforementioned cold plate 10, multiple of the aforementioned second plates 2 may be stacked in one or more of the uppermost layer and the lowermost layer.

[0143] Therefore, in the aforementioned cold plate 10, one or more of the lowermost upper layer and the uppermost lower layer can be formed to be thicker than the other layers of the second layer and the third layer.

[0144] Each long side and a portion of each short side of the cold plate 10 formed by stacking the first plate 1 to the third plate 3 can be formed by stacking the first plate 1.

[0145] Furthermore, in the aforementioned cold plate 10, each of the plurality of cooling flow paths 9 and a portion of each of the aforementioned short side portions can be formed by laminating the aforementioned second plate 2.

[0146] Furthermore, in the aforementioned cold plate 10, each of the aforementioned plurality of cooling fins 8 and a portion of each of the aforementioned short side portions can be formed by laminating the aforementioned third plate 3.

[0147] In the aforementioned cold plate 10, by stacking the first plate 1 to the third plate 3 in this way, the upper and lower frames of the cold plate 10 can be formed by the stacked structure of the first plate 1, the cooling section 6 is formed by the stacked structure of the second plate 2 with the flow path holes 2h and the third plate 3 with the through holes 3h, and the side frame of the cold plate 10 is formed by the side of each of the first plate 1 to the third plate 3.

[0148] An example of the cold plate 10 formed by stacking the first plate 1 to the third plate 3 as described above can be shown as follows: Figure 5 as well as Figure 6 As shown.

[0149] like Figure 5 as well as Figure 6As shown, in the aforementioned cold plate 10, the aforementioned cooling section 6 is formed inside except for the outer frame, and the aforementioned cooling water flows in and out in the aforementioned cooling section 6.

[0150] In the cooling section 6, the side flow path 7 is formed along the inner side of the outer frame, and the plurality of cooling fins 8 are formed vertically between the surface that contacts the object to be cooled 20 and the surface that faces it. The plurality of cooling flow paths 9 are formed by the interval between each of the plurality of cooling fins 8.

[0151] One of the flow paths in the side flow path 7 described above can extend along the side.

[0152] That is, the above-mentioned side flow path 7 can be formed into a shape in which a flow path extends along the above-mentioned side.

[0153] The aforementioned side flow path 7 can be formed such that the flow paths of the left side end, right side end, upper side end, and lower side end are connected to form a flow path shape.

[0154] The left end and the right end are formed by the two ends of the flow path hole 2h of the second plate 2 and the through hole 3h of the third plate 3, and the upper end and the lower end can be formed by the flow path hole 2h of the second plate 2.

[0155] The aforementioned side flow path 7 can be configured to have a wider width than the aforementioned plurality of cooling flow paths 9.

[0156] Therefore, the flow rate of the cooling water flowing along the side flow path 7 can be greater than that of the multiple cooling flow paths 9.

[0157] Therefore, the through hole 3h is formed to have a width wider than the aforementioned certain interval, and the second plate 2, which is equivalent to the upper layer above the lowermost end and the lower layer below the uppermost end, can be stacked with a thickness greater than the aforementioned certain interval.

[0158] The aforementioned cooling fins 8 can be formed to have a thickness of 0.1 mm to 2.0 mm.

[0159] That is, the third plate 3 mentioned above can be stacked in an amount equivalent to a thickness of 0.1 mm to 2.0 mm in the third layer.

[0160] In this case, preferably, the thickness of the third plate 3 can be formed to be from 0.1 mm to 2.0 mm, so that one of the third plates 3 is stacked in each of the third layers.

[0161] Furthermore, in this case, the thickness of the second plate 2 can also be formed to be 0.1 mm to 2.0 mm.

[0162] The aforementioned cooling fins 8 can be formed with a width of 1mm to 20mm.

[0163] The width of the plurality of cooling fins 8 can represent the height of the plurality of cooling fins 8 erected from one side to the other side.

[0164] On the other hand, when the width of the plurality of cooling fins 8 is as described above, preferably, the flow path hole 2h of the second plate 2 and the through hole 3h of the third plate 3 can also be formed to a width of 1mm to 20mm.

[0165] The aforementioned multiple cooling fins 8 can be arranged at the same intervals.

[0166] The aforementioned multiple cooling fins 8 can be arranged with intervals ranging from 0.1 mm to 5.0 mm.

[0167] That is, the above-mentioned multiple cooling flow paths 9 can be formed with an interval of 0.1mm to 5.0mm.

[0168] Therefore, the second sheet 2 described above can be stacked in a quantity with a thickness of 0.1 mm to 5.0 mm in the second layer.

[0169] Furthermore, in the cooling section 6, the cooling fins disposed at the uppermost and lowermost ends each form a partition 8' in the longitudinal direction, thereby separating the inner side F of the partition and the side flow path 7.

[0170] That is, the cooling fins disposed at the uppermost and lowermost ends of the plurality of cooling fins 8 are formed as partition fins 8' for dividing the region F in which the side flow path 7 and the plurality of cooling fins 8 are formed.

[0171] When the cooling section 6 is formed in this structure, the inlet 4 and outlet 5 are formed on the above-mentioned side, so that the cooling water can flow in and out.

[0172] When the cooling section 6 is formed in this way, the example of forming the inlet 4 and the outlet 5, and the flow of the cooling water based thereon, can be as follows: Figure 7 as well as Figure 8 As shown.

[0173] like Figure 7 As shown, in Figure 5 as well as Figure 6 In the cold plate 10 shown above, the inlet 4 and the outlet 5 can be formed at both ends of the above side respectively.

[0174] Thus, the inflow and outflow of cooling water are realized at the location corresponding to the area of ​​the side flow path 7, allowing the cooling water to flow inside the cooling section 6, such as... Figure 8 As shown.

[0175] In this case, the cooling water flows into one end of the cooling section 6 through the inlet 4, and flows to the other end of the cooling section 6 where the outlet 5 is formed through the side flow path 7 and the plurality of cooling flow paths 9 respectively, and then flows out through the outlet 5.

[0176] During the flow of the cooling water described above, heat exchange occurs between the cooling water and the multiple cooling fins 8 arranged on both sides of each of the multiple cooling flow paths 9, thereby enabling cooling of each of the multiple cooling fins 8.

[0177] Thus, in the aforementioned cold plate 10, the aforementioned cooling section 6 is configured as follows: Figure 5 as well as Figure 6 The structure shown allows the cooling water to circulate throughout the entire interior of the cooling section 6, thus achieving uniform cooling.

[0178] This increases the cooling range and efficiency of the aforementioned cold plate 10, thereby improving cooling performance.

[0179] On the other hand, the flow path structure of the cooling section 6 can be changed according to the shape of the third plate 3 in the aforementioned cold plate 10.

[0180] For example, by processing the third plate 3 into different shapes, the region F in which the plurality of cooling fins 8 are formed can be divided into multiple regions, thereby increasing the flow path of the cooling water.

[0181] Another example of the aforementioned third board material 3 can be as follows: Figure 9 As shown.

[0182] like Figure 9 As shown, another example 3' (hereinafter referred to as another plate) of the third plate 3 can also form the through hole 3h in the central part.

[0183] That is, the other plate 3' can be formed in the shape of the through hole 3h in the central part, based on the shape of the through hole 3h formed at one end and the other end.

[0184] When this other plate 3' is stacked, each of the plurality of cooling fins 8 can be divided into two regions with respect to the central axis through the through hole 3h formed in the central part.

[0185] Therefore, additional flow paths can be formed along the central axis of the segment.

[0186] This further layering, as... Figure 9 The example of the cold plate 10 formed by the other sheet 3' shown above can be as follows: Figure 10 as well as Figure 11 As shown.

[0187] like Figure 10 as well as Figure 11 As shown, in the cold plate 10 formed from the other plate 3', the region F in which the plurality of cooling fins 8 are formed can be divided into two regions: a first region F1 and a second region F2.

[0188] The cooling section 6 may also include a central flow path 9', through which the central axis of the cooling fins disposed between the uppermost and lowermost ends 8' of the plurality of cooling fins 8 passes, thereby forming the central flow path 9' along the central axis.

[0189] That is, in the cooling section 6, through the through hole 3h formed in the central part of the other plate 3', a central flow path 9' can be formed along the central axis of the cooling fins arranged between the uppermost and lowermost ends 8' of the plurality of cooling fins 8.

[0190] Therefore, the cooling section 6 further forms a central flow path 9' between the first region F1 and the second region F2, through which the cooling water can flow via the side flow path 7, the plurality of cooling flow paths 9 and the central flow path 9'.

[0191] The aforementioned central flow path 9' can be configured to have a wider width than the aforementioned plurality of cooling flow paths 9.

[0192] Therefore, the flow rate of the cooling water flowing along the central flow path 9' can be greater than that of the multiple cooling flow paths 9.

[0193] Therefore, the through hole 3h formed in the central part can be formed to be wider than the aforementioned fixed interval.

[0194] When the cooling section 6 is formed in this way, the example of forming the inlet 4 and the outlet 5, and the flow of the cooling water based thereon, can be as follows: Figure 12 as well as Figure 13 As shown.

[0195] like Figure 12 As shown, Figure 10 as well as Figure 11 In the cold plate 10 shown above, the inlet 4 can be formed on the central side of the above-mentioned side, and the outlets 5a and 5b can be formed at both ends of the above-mentioned side respectively.

[0196] Thus, the cooling water flows in at the location corresponding to the central flow path 9' region and flows out at the location corresponding to the side flow path 7 region, allowing the cooling water to flow inside the cooling section 6. Figure 13 As shown.

[0197] In the aforementioned cooling section 6, when the cooling water flows in, the cooling water is diverted to each of the plurality of cooling flow paths 9 after passing through the central flow path 9', and then can flow to the side flow path 7.

[0198] In this case, the cooling water flows into the central side of the cooling section 6 through the inlet 4, flows through the central flow path 9' and each of the plurality of cooling flow paths 9, flows to both ends of the cooling section 6 where the outlets 5a and 5b are formed, and then flows out through each of the outlets 5a and 5b.

[0199] Therefore, the cooling water can flow from the central side of the cooling section 6 through the central flow path 9' and each of the plurality of cooling flow paths 9 to the side flow path 7.

[0200] In particular, by directing the cooling water into the central side, which is concentrating the heat transferred from the object to be cooled 20 and thus has a relatively higher temperature than the side, not only can the high-temperature central side be effectively cooled, but the temperature within the cold plate 10 can also be balanced (balanced cooling / balanced heat dissipation).

[0201] And, as Figure 10 as well as Figure 11 As shown, when the cooling section 6 is formed, another example of forming the inlet 4 and the outlet 5 is given, and the flow of the cooling water based thereon can be as follows: Figure 14 as well as Figure 15 As shown.

[0202] like Figure 14 As shown, Figure 10 as well as Figure 11 In the cold plate 10 shown above, the inlet 4 can be formed on the central side of the above-mentioned side, and the outlet 5 can be formed at either end (the other end) of the above-mentioned side.

[0203] Thus, the cooling water flows in at the location corresponding to the central flow path 9' region and flows out at the location corresponding to the side flow path 7 region, allowing the cooling water to flow inside the cooling section 6. Figure 15 As shown.

[0204] In the aforementioned cooling section 6, when the cooling water flows in, the cooling water is diverted to each of the plurality of cooling flow paths 9 after passing through the central flow path 9', and then can flow to the side flow path 7.

[0205] In this case, the cooling water flows into the central side of the cooling section 6 through the inlet 4, flows through the central flow path 9', the plurality of cooling flow paths 9 and each of the side flow paths 7, flows to the other end of the cooling section 6 where the outlet 5 is formed, and then flows out through the outlet 5.

[0206] The aforementioned cold plate 10 can be combined (installed, equipped with) multiple components for use after the aforementioned inlet 4 and outlet 5 are formed, and can be installed on the object to be cooled 20.

[0207] Examples of the various configurations and combinations of the aforementioned cold plate 10 can be seen as follows: Figures 16 to 18 As shown.

[0208] like Figure 16 As shown, in the above-mentioned cold plate 10, each of the above-mentioned inlet 4 and the above-mentioned outlet 5 can be combined with an inlet connector 40 and an outlet connector 50 for the inflow and outflow of the cooling water.

[0209] Each of the aforementioned inlet connector 40 and outlet connector 50 is connected to a hose for supplying cooling water, through which the cooling water can be supplied.

[0210] like Figure 17 As shown, the support 30 can be attached to one side of the cold plate 10.

[0211] The aforementioned support 30 can act as a cover to protect the aforementioned side, and can also act as a heat conductor to transfer and dissipate heat emitted from the aforementioned side.

[0212] The aforementioned support 30 can be formed in a shape that covers at least two-thirds of the area of ​​the aforementioned side.

[0213] Furthermore, configuration slots 30a and 30b can be formed on the aforementioned bracket 30. When combined with the aforementioned side, each of the aforementioned inflow connector 40 and the aforementioned outflow connector 50 is configured in the configuration slots 30a and 30b.

[0214] The aforementioned cold plate 10 incorporates the aforementioned support 30, inflow connector 40, and outflow connector 50, thereby enabling it to... Figure 18 The shape shown is installed on the object 20 to be cooled.

[0215] On the other hand, in the layering, as Figure 3The first plate 1, the second plate 2, and the third plate 3 shown above are arranged in multiple layers and then cut, so that multiple cold plates 10 as described above can be manufactured in one process.

[0216] The process of manufacturing multiple cold plates 10 can be as follows: Figures 19 to 22 As shown.

[0217] The process of manufacturing the above-mentioned multiple cold plates 10 is as follows: Figure 19 As shown, multiple plates 11, 21, and 31 are formed by arranging each of the first plate 1, the second plate 2, and the third plate 3 in a plurality of arrangements, as follows: Figure 20 As shown, multiple sheets of material 11, 21, and 31 are stacked in a specific order as described above. Figure 21 As shown, after joining the laminate 100 consisting of the multiple plates 11, 21, and 31, as shown... Figure 22 As shown, the laminate 100 is cut according to the arrangement of the multiple plates 11, 21, 31, and each cut body 10 is processed to manufacture the multiple cold plates 10.

[0218] like Figure 19 As shown, each of the above-mentioned multiple boards 11, 21, and 31 can be a board in which each of the above-mentioned first board 1, the above-mentioned second board 2, and the above-mentioned third board 3 are arranged in multiple rows and multiple columns.

[0219] By stacking multiple of the aforementioned plates 11, 21, and 31 in a specific order, a quantity of the aforementioned cold plates 10 equivalent to the aforementioned arrangement units can be manufactured.

[0220] The aforementioned multiple panels 11, 21, and 31 can be stacked with their sides aligned.

[0221] like Figure 20 As shown, the aforementioned multiple plates 11, 21, and 31 can be stacked in the following manner: a first row of plates 11 of the first plate 1 is arranged at the bottom and top, a second row of plates 21 of the second plate 2 and a third row of plates 31 of the third plate 3 are alternately arranged between the bottom and top.

[0222] Thus, the upper and lower frames of the laminate can be formed by the stacked structure of the first arrangement of plates 11, the internal flow path structure of the laminate 100 can be formed by the stacked structure of the second arrangement of plates 21 with flow path holes 2h and the third arrangement of plates 31 with through holes 3h, and the side frame of the laminate 100 can be formed by the side of each of the first arrangement of plates 11 to the third arrangement of plates 31.

[0223] Among them, one or more of the first row of plates 11 to the third row of plates 31 can be stacked in the stacked layers.

[0224] For example, multiple first-arranged plates 11 may be stacked at each of the lowermost and uppermost layers, or multiple second-arranged plates 21 may be stacked in one or more of the multiple layers in which the second-arranged plates 21 are arranged.

[0225] Therefore, the thickness (height) of one or more of the multiple layers of the aforementioned laminate 100 can be different from the other layers.

[0226] Before contact, the sides of the aforementioned stacked body 100 are aligned.

[0227] like Figure 21 As shown, in the above-mentioned laminate 100, the above-mentioned multiple plates 11, 21, 31 are aligned with the same vertical axis.

[0228] In the aforementioned laminate 100, the plurality of plates 11, 21, and 31 are joined together after being arranged so that each side has a planar shape.

[0229] In the aforementioned laminate 100, each of the plurality of plates 11, 21, and 31 can be joined in a manner that allows for diffusion bonding of the contact portions.

[0230] That is, each of the above-mentioned multiple cold plates 10 can be joined together by diffusion bonding of the above-mentioned first plate 1, the above-mentioned second plate 2 and the above-mentioned third plate 3.

[0231] The aforementioned diffusion bonding refers to a method of bonding two components by pressing them together under reasonable heating and pressurization conditions within a specified range and heating them to a temperature below their melting point, thereby utilizing the principle of atomic diffusion between the bonding surfaces to achieve a bonding method without defects such as pores.

[0232] In the aforementioned laminate 100, the overlapping portions of the multiple plates 11, 21, and 31 can also be joined by brazing.

[0233] In the aforementioned laminate 100, if the plurality of plates 11, 21, and 31 are made of non-metallic materials, the overlapping portions of the plurality of plates 11, 21, and 31 can also be joined by adhesive bonding or ultrasonic welding.

[0234] In the aforementioned laminate 100, except for the corner portions, the portions where the multiple plates 11, 21, and 31 are joined are cut, thereby dividing it into multiple cut bodies 10.

[0235] like Figure 22 As shown, the aforementioned laminate 100 can be cut along one or more of the first axis 1X corresponding to the length direction and the second axis 2X corresponding to the width direction, and along the third axis 3X corresponding to the height direction.

[0236] The above-mentioned stacked body 100 can be cut on the third axis 3X according to the above-mentioned arrangement units.

[0237] For example, if the above arrangement unit is 10 rows × 2 columns, it is possible to cut along the third axis 3X, which is equivalent to each of the 9 cutting rows between each of the above 10 rows and the 1 cutting column between each of the above 2 columns.

[0238] Therefore, the aforementioned laminate 100 can be divided into 20 of the aforementioned cut bodies 10.

[0239] Then, each of the aforementioned cutting bodies 10 is processed into a shape having the aforementioned inlet 4 and the aforementioned outlet 5. Afterwards, the aforementioned bracket 30, the aforementioned inlet connector 40 and the aforementioned outlet connector 50 are combined with each of the aforementioned plurality of cold plates 10, and the manufacturing of the aforementioned plurality of cold plates 10 can be completed.

[0240] Therefore, by stacking the above-mentioned multiple plates 11, 21, and 31, the above-mentioned multiple cold plates 10 can be manufactured in a single manufacturing process.

[0241] The embodiments of the cold plate have been described so far. It should be understood that various modifications can be made to the embodiments described without departing from the scope of the invention, and the scope of the invention is not limited to the described embodiments.
