Description

Technical Field

[0001] The present application relates to the technical field of fin processing, and more specifically, to a fin processing technology and a processing device. Background Art

[0002] The water-cooled plate includes two sealed shells, which enclose an internal flow channel, and fins are arranged in the internal flow channel. When used, the water-cooled plate is generally used in conjunction with several electronic components to be cooled. Since the design heights of various electronic components are different, the required shell is not flat, resulting in height differences at different positions of the internal flow channel, and different fin heights are required. In the prior art, multiple fins of different heights are generally used, and each fin is positioned and installed at different positions of the internal flow channel through positioning protrusions provided on the shell.

[0003] However, the positioning protrusion can only ensure the positioning accuracy between the fin and the shell, and it is difficult to ensure the precise positioning of adjacent fins.

[0004] Therefore, for those skilled in the art, it is urgent to solve the problem that fins of different heights are difficult to position relative to each other. Summary of the invention

[0005] In view of this, the present application provides a fin processing technology, which performs two stamping processes on the workpiece, not only forming a first fin with a first height, but also forming a second fin with a second height, so that the fin heights of different areas in the processed fin product are different, ensuring that the fin product meets the different requirements for fin heights at various locations in the internal flow channel of the water-cooled plate. There is no need to configure multiple fin products of different heights as in the prior art to be respectively assembled into the internal flow channel of the water-cooled plate, and there is no need to position the fin products of different heights relative to each other, which fundamentally solves the problem of difficulty in positioning multiple fin products of different heights relative to each other in the prior art. The present application also provides a processing device, which makes the fin heights of different areas in the fin product different, meeting the different requirements for fin heights at different locations in the internal flow channel of the water-cooled plate. There is no need to position and assemble multiple fin products of different heights in the water-cooled plate as in the prior art, avoiding the problem of difficulty in positioning fins of different heights relative to each other.

[0006] To achieve the above purpose, one embodiment of the present application provides the following technical solution:

[0007] A fin processing technology, characterized by comprising:

[0008] Providing workpieces to be processed;

[0009] Forming the first fin: using a first stamping die to stamp the workpiece to be processed to form a plurality of fin units arranged side by side; the fin unit comprises a first convex portion and a second convex portion arranged alternately; the fin unit comprises a bottom plate and a top plate, and the distance from the bottom plate to the top plate is a first height;

[0010] Forming the second fin: using a second stamping die to stamp out part of the first protrusion and / or the second protrusion to form a first sub-protrusion and / or a second sub-protrusion; the distance from the top of the first sub-protrusion or the second sub-protrusion to the bottom plate of the fin unit is a second height, and the first height is greater than the second height.

[0011] This processing technology performs two stamping processes on the workpiece, not only forming a first fin with a first height, but also forming a second fin with a second height, so that the fin heights of different areas of the processed fin product are different, meeting the different requirements for fin heights at different positions in the internal flow channel of the water-cooled plate. In the prior art, multiple fin products of different heights are used for positioning and installation to meet the different requirements for fin heights at different positions in the internal flow channel of the water-cooled plate. It is difficult to position multiple fins of different heights relative to each other. However, this solution does not require the assembly of multiple fin products of different heights into the internal flow channel of the water-cooled plate, and does not require the positioning of different fin products relative to each other, thereby solving the problem of the difficulty of positioning multiple fins of different heights relative to each other in the prior art.

[0012] One embodiment of the present application provides the following technical solution:

[0013] A processing device for processing a fin, comprising: a first stamping die and a second stamping die arranged in sequence along a first direction; the processing device also comprises a first lower die matched with the first stamping die and a second lower die matched with the second stamping die;

[0014] In the height direction, the length of the first stamping die is greater than the length of the second stamping die, the first stamping die and the first lower die cooperate to stamp out a first fin having a first height for the workpiece to be processed, and the second stamping die and the second lower die cooperate to stamp out a second fin having a second height;

[0015] The processing equipment also includes a conveying device, which can drive the workpiece to be processed to move along the transmission direction.

[0016] The processing equipment provided in the present application makes the fin heights of different areas in the fin product different, thereby meeting the different requirements for fin heights at different positions in the internal flow channel of the water-cooling plate. There is no need to position and assemble multiple fin products of different heights in the water-cooling plate as in the prior art, thus avoiding the problem of difficulty in positioning fins of different heights relative to each other.

[0037] The embodiment of the present application discloses a fin processing technology, which performs two stamping processes on the workpiece, not only forming a first fin with a first height, but also forming a second fin with a second height, so that the fin heights of different areas in the processed fin product are different, ensuring that the fin product meets the different requirements for fin heights at various locations of the internal flow channel of the water-cooled plate, and there is no need to configure multiple fin products of different heights as in the prior art to be respectively assembled into the internal flow channel of the water-cooled plate, and there is no need to position the fin products of different heights relative to each other, thereby solving the problem of difficulty in positioning multiple fin products of different heights relative to each other in the prior art from the root. The embodiment of the present application also discloses a processing device, which makes the fin heights of different areas in the fin product different, meeting the different requirements for fin heights at different locations of the internal flow channel of the water-cooled plate, and there is no need to position and assemble multiple fin products of different heights in the water-cooled plate as in the prior art, thereby avoiding the problem of difficulty in positioning fins of different heights relative to each other.

[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] See also Figure 1-Figure 14 , the embodiment of the present application provides a fin processing process, including:

[0040] Provide a workpiece to be processed; the workpiece can be set to be flat, warped, or set to be a plate with protrusions, etc. This embodiment does not limit the shape and structure of the workpiece, but only needs to ensure that it can be formed into a fin after subsequent processing;

[0041] Forming the first fin 100: using the first stamping die 308 to stamp the workpiece to be processed to form a plurality of fin units 10 arranged side by side; the fin unit 10 includes a first convex portion 101 and a second convex portion 102 arranged alternately, and the fin unit 10 includes a bottom plate 104 and a top plate 103, and the distance from the bottom plate 104 of the fin unit 10 to the top plate 103 of the fin unit 10 is a first height h1;

[0042] Forming the second fin 200: Use the second stamping die 306 to stamp out part of the first protrusion 101 and / or the second protrusion 102 to form a first sub-protrusion 201 and / or a second sub-protrusion 202; the distance from the top of the first sub-protrusion 201 or the second sub-protrusion 202 to the bottom plate 104 of the fin unit 10 is the second height h2, and the first height h1 is greater than the second height h2.

[0043] In the step of forming the first fin 100, each fin unit 10 can be arranged to be spaced and arranged side by side, or in a plurality of adjacent fin units 10, some areas are spaced from each other and some areas are combined into one, which is not limited in this embodiment. The staggered arrangement of the first protrusion 101 and the second protrusion 102 in the fin unit 10 means that the first protrusion 101 protrudes from the second protrusion 102 along the first direction, and the second protrusion 102 protrudes from the first protrusion 101 in the opposite direction of the first direction. The fin unit 10 extends along the second direction, and the second direction is perpendicular to the first direction; along the second direction, the first protrusion 101 and the second protrusion 102 of the fin unit 10 are arranged alternately.

[0044] In the step of forming the first fin 100, the first stamping die 308 stamps the workpiece to be processed along the transmission direction of the workpiece to be processed or the first direction (the transmission direction of the workpiece to be processed is the same direction as the first direction), and punches out each fin unit 10 in sequence; the first top 112 of the first protrusion 101 and the second top 122 of the second protrusion 102 are coplanar, and the first tops 112 of all the first protrusions 101 and the second tops 122 of all the second protrusions 102 in each fin unit 10 form the above-mentioned top plate 103.

[0045] The first convex portion 101 includes a first window piece 111, a first top portion 112, and a second window piece 113 connected in sequence along a first direction; an end of the first window piece 111 away from the first top portion 112 and an end of the second window piece 113 away from the first top portion 112 are respectively connected to the bottom plate 104. The second convex portion 102 includes a third window piece 121, a second top portion 122, and a fourth window piece 123 connected in sequence along the first direction; an end of the third window piece 121 away from the second top portion 122 and an end of the fourth window piece 123 away from the second top portion 122 are respectively connected to the bottom plate 104.

[0046] In the above fin processing technology, when the first stamping die 308 is used to stamp the workpiece to be processed, the first lower die 314 is used to support the workpiece to be processed; when the second stamping die 306 is used to stamp part of the first convex portion 101 and / or the second convex portion 102, the second lower die 318 is used to support the part of the first convex portion 101 and / or the second convex portion 102. Specifically, the second stamping die 306 forms the first sub-convex portion 201 when stamping the first convex portion 101, and forms the second sub-convex portion 202 when stamping the second convex portion 102.

[0047] In some embodiments, after the step of forming the first fin 100 and before the step of forming the second fin 200, the process further includes: moving the formed first fin 100 along the transmission direction of the workpiece to be processed or the first direction to the second stamping die 306. When the fin processing technology provided by this embodiment is applied, the first stamping die 308 and the second stamping die 306 need to be arranged in sequence along the transmission direction (i.e., the first direction) of the workpiece to be processed.

[0048] In some embodiments, after the step of forming the first fin 100 and before the step of forming the second fin 200, the process further includes: rotating the first stamping die 308 and the second stamping die 306 to switch positions so that the second stamping die 306 is located above a portion of the first convex portion 101 and / or the second convex portion 102. When the fin processing technology provided in this embodiment is applied, the first stamping die 308 and the second stamping die 306 need to be respectively installed on the first rotating bracket, and the positions of the two stamping dies can be adjusted by rotating the first rotating bracket.

[0049] In some embodiments, after the step of forming the first fin 100 and before the step of forming the second fin 200, the process further includes: removing the first stamping die 308 and replacing the second stamping die 306. When the stamping fin processing technology provided by this embodiment is applied, the first stamping die 308 and the second stamping die 306 need to be installed at the same position. The first stamping die 308 needs to be installed at the position during the process of forming the first fin 100, and the second stamping die 306 needs to be installed at the position during the process of forming the second fin 200.

[0050] In the step of forming the second fin 200, when stamping a portion of the first convex portion 101 and / or the second convex portion 102, the connection portion 131 between the first convex portion 101 and the adjacent second convex portion 102 is cut off. In this embodiment, the above-mentioned cutting off of the connection portion 131 between the first convex portion 101 and the adjacent second convex portion 102 is achieved by the first stamping die 308 and the first lower die 314 being combined.

[0051] In the fin processing technology, when performing the second stamping, the first stamping die 308 and the first lower die 314 are used to close the mold to first cut off the connecting portion 131 between the first protrusion 101 and the adjacent second protrusion 102, so as to avoid the first protrusion 101 and the adjacent second protrusion 102 and / or the second protrusion 102 and the adjacent first protrusion 101 pulling each other to cause wrinkles, thereby improving the forming effect of the first sub-protrusion 201 and / or the second sub-protrusion 202.

The cutting step can be performed using a cutter.

[0053] During the process of forming the second fin 200, the second stamping die 306 is used to stamp out part of the first protrusion 101 and / or the second protrusion 102, and the first sub-protrusion 201 and / or the second sub-protrusion 202 are stamped out in one piece, that is, the second stamping die 306 can perform a single stamping to form the first protrusion 101 and / or the second protrusion 102 to be stamped in a fin unit 10 into the first sub-protrusion 201 and / or the second sub-protrusion 202, respectively.

[0054] In some embodiments, the first sub-protrusion 201 includes a plurality of first high-level segments 2011 and a plurality of first low-level segments 2012, with first low-level segments 2012 disposed between adjacent first high-level segments 2011, and / or the second sub-protrusion 202 includes a plurality of second high-level segments 2021 and a plurality of second low-level segments 2022, with second low-level segments 2022 disposed between adjacent second high-level segments 2021.

The first high-level section 2011 includes a fifth window piece 211 and a third top 212 connected to each other; the first low-level section 2012 includes a first transition plate 213, a first connecting plate 214, and a second transition plate 215 connected in sequence; the third tops 212 of the two first high-level sections 2011 are coplanar and constitute the top of the first sub-convex portion 201; the fifth window piece 211 is connected to the bottom plate 104; the first transition plate 213 and the second transition plate 215 are respectively connected to the two third tops 212; and the first connecting plate 214 is located between the third top 212 and the bottom plate 104.

[0056] like Figure 5 As shown, the second sub-convex portion 202 includes two second high-level sections 2021 and a second low-level section 2022 located between the two second high-level sections 2021. The second high-level section 2021 includes a sixth window piece 221 and a fourth top 222 connected to each other; the second low-level section 2022 includes a third transition plate 223, a second connecting plate 224 and a fourth transition plate 225 connected in sequence; the fourth tops 222 of the two second high-level sections 2021 are coplanar and constitute the top of the second sub-convex portion 202; the sixth window piece 221 is connected to the bottom plate 104; the third transition plate 223 and the fourth transition plate 225 are respectively connected to the two fourth tops 222; and the second connecting plate 224 is located between the fourth top 222 and the bottom plate 104.

The first sub-protrusion 201 and the second sub-protrusion 202 may also be respectively configured to include only one low segment, the top of which is concave and concave toward the bottom plate 104. This embodiment does not limit the specific structural form of the first sub-protrusion 201 or the second sub-protrusion 202, and only needs to ensure that the distance from the top of the first sub-protrusion 201 or the second sub-protrusion 202 to the bottom plate 104 of the fin unit 10 is the second height h2.

[0058] The fin product processed by the above fin processing technology only has the first sub-protrusion 201 or only has the second sub-protrusion 202, and correspondingly, a plurality of first sub-protrusions 201 or a plurality of second sub-protrusions 202 are aligned along the first direction. Of course, the fin product processed by the above fin processing technology can also be configured to have both the first sub-protrusion 201 and the second sub-protrusion 202, wherein a plurality of first sub-protrusions 201 are aligned along the first direction, and a plurality of second sub-protrusions 202 are aligned along the first direction; the first sub-protrusions 201 and the second sub-protrusions 202 are staggered along the second direction, such as Figure 3 shown.
