[0046] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0047] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0048] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence.

Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0050] The technical solution of this embodiment will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and examples can be combined with each other.

[0051] According to embodiments of the present invention, such as Figures 1-5 As shown, a processing apparatus for a toothed radiator is proposed. The processing apparatus includes a scraper 4 and a forming assembly, wherein the scraper 4 is used to scrape out heat dissipation teeth 2 from the surface of the radiator substrate 3. Exemplarily, the scraper 4 travels along the length direction of the substrate 3 and scrapes out heat dissipation teeth 2 on the surface of the substrate 3, the length direction of the substrate 3 being referenced to... Figure 1The direction is shown by the X2 axis. The substrate 3 is made of a material with excellent thermal conductivity, such as copper, aluminum, or their alloys. The remaining portion of the substrate 3 after removing the heat dissipation teeth 2 in the thickness direction forms the substrate 1 of the heat sink, and the heat dissipation teeth 2 are integrally formed with the substrate 1. The molding assembly includes a first molding part 5 and a second molding part 6. The first molding part 5 has a first molding structure 51, and the second molding part 6 has a second molding structure 61 that mates with the first molding structure 51. The teeth, the first molding part 5, and the second molding part 6 are all made of a material with high hardness, such as stainless steel. After the scraper 4 removes the heat dissipation teeth 2 from the surface of the substrate 3, the first molding part 5 is used to mold the first surface of the heat dissipation teeth 2, and the first molding structure 51 forms a first pattern on the first surface of the heat dissipation teeth 2; the second molding part 6 is used to mold the second surface of the heat dissipation teeth 2 that is opposite to the first surface, and the second molding structure 61 forms a second pattern on the second surface of the heat dissipation teeth 2. Both the first and second patterns are three-dimensional patterns to increase the heat dissipation area of ​​the heat dissipation teeth 2.

[0052] like Figure 1 , Figure 4 and Figure 5 As shown, in the working state, the heat dissipation tooth 2 is located between the first pressing part 5 and the second pressing part 6. The first pressing part 5 and the second pressing part 6 are pressed together, and the first pressing structure 51 and the second pressing structure 61 are fitted together to form a preset pattern on the surface of the heat dissipation tooth 2. In this embodiment, the preset pattern can be formed only on the first surface or the second surface of the heat dissipation tooth 2, for example, a three-dimensional pattern with alternating concave and convex portions can be formed on the first surface or the second surface of the heat dissipation tooth. In this embodiment, the preset pattern can also be formed on both the first surface and the second surface of the heat dissipation tooth 2.

[0053] When preset patterns are formed on both the first and second surfaces of the heat dissipation denticle 2, the pattern corresponding to the preset pattern on the first surface is the first pattern, and the pattern corresponding to the preset pattern on the second surface is the second pattern. In one example, the preset pattern includes multiple recesses 2111 and multiple protrusions 2112, which are alternately arranged in the height direction of the heat dissipation denticle 2, with the height direction of the heat dissipation denticle 2 referring to... Figure 6 and Figure 7 The direction indicated by the Y1 axis. A preset angle is formed between the height direction of the heat dissipation teeth 2 and the substrate 3. This preset angle is greater than 0 degrees and less than 180 degrees; preferably, the preset angle is 90 degrees. It should be noted that after the scraper 4 scrapes the heat dissipation teeth 2 from the surface of the substrate 3, the pressing process of the first pressing part 5 and the second pressing part 6 on the heat dissipation teeth 2 can be performed before or after the heat dissipation teeth 2 are straightened. To ensure sufficient operating space and to guarantee the pressing effect, it is preferable to press the heat dissipation teeth 2 to form a preset pattern before the heat dissipation teeth 2 are straightened.

[0054] In other possible implementations, the preset pattern includes multiple recesses spaced apart, or multiple convexities spaced apart, or multiple irregularly arranged recesses and multiple convexities. The structure of the preset pattern can be flexibly determined based on various factors such as the heat dissipation performance requirements of the radiator and the difficulty of manufacturing processes.

[0055] The processing apparatus of this embodiment is provided with a first pressing part 5 and a second pressing part 6. After the scraper 4 scrapes out the heat dissipation teeth 2 from the surface of the substrate 3, the first pressing part 5 and the second pressing part 6 directly press and cooperate with the heat dissipation teeth 2, thereby forming a preset pattern on the surface of the heat dissipation teeth 2. This realizes the addition of the heat dissipation teeth 2 extrusion molding process to the heat dissipation teeth 2 processing, effectively reducing the processing difficulty of the heat dissipation teeth 2 with uneven surfaces and improving processing efficiency.

[0056] In some implementations, such as Figure 2 As shown, the top of the scraper 4 is provided with a supporting inclined surface 41. The supporting inclined surface 41 is used to support the heat dissipation teeth 2 during the process of the scraper 4 scraping out the heat dissipation teeth 2 from the surface of the substrate 3. The first pressing part 5 is disposed on the supporting inclined surface 41. The first pressing part 5 can be integrally formed with the supporting inclined surface 41, or it can be disposed independently of the supporting inclined surface 41, and can be disposed on the supporting inclined surface 41 by means of snap-fit, plug-in, connector connection, bonding or welding. In this embodiment, by disposing the first pressing part 5 on the supporting inclined surface 41, after the scraper 4 scrapes out the heat dissipation teeth 2 from the surface of the heat dissipation teeth 2, before straightening the heat dissipation teeth 2, the second pressing part 6 can be controlled to move directly to the first pressing part 5 and press and cooperate with the first pressing part 5, thereby reducing additional mold costs and saving the moving time of the first pressing part 5, reducing production costs and improving pressing efficiency.

[0057] In other possible ways, such as Figure 4 As shown, the first pressing part 5 is separately disposed from the scraper 4 to protect the scraper 4. In the working state, after the scraper 4 scrapes out the heat dissipation teeth 2 from the surface of the substrate 3 and returns to its initial position, the first pressing part 5 can be moved in a controlled manner between the scraper 4 and the heat dissipation teeth 2 and fits against the heat dissipation teeth 2. Specifically, the top of the scraper 4 is provided with a supporting inclined surface 41, and the angle between the supporting inclined surface 41 and the substrate 3 is A. The supporting inclined surface 41 is used to support the heat dissipation teeth 2 during the process of the scraper 4 scraping out the heat dissipation teeth 2 from the surface of the substrate 3. The first pressing part 5 includes a first pressing surface 501, and the angle between the first pressing surface 501 and the substrate 3 is B, satisfying A=B. After the scraper 4 scrapes out the heat dissipation teeth 2 from the surface of the substrate 3 and returns to its initial position, the angle between the heat dissipation teeth 2 and the substrate 3 is A. The first pressing part 5 can be controlled to move to the heat dissipation teeth 2 and fit against the first surface of the heat dissipation teeth 2.

[0058] In some implementations, such as Figure 2As shown, the first molding part 5 includes a first molding surface 501, which is used to fit against the first surface of the heat dissipation tooth 2. A first molding structure 51 is disposed on the first molding surface 501. The first molding structure 51 can be integrally formed with the first molding surface 501, or it can be disposed independently of the first molding surface 501 by means of snap-fit, plug-in, connector connection, bonding or welding.

[0059] In one example, the first forming structure 51 includes a plurality of first dies 511 and a plurality of first punches 512, the plurality of first dies 511 and the plurality of first punches 512 being alternately arranged in a first direction of the first forming surface 501. The first direction is, for example, the inclined direction of the first forming surface 501, i.e., referring to... Figure 2 The direction indicated by the Z2 axis. When the first forming part 5 is provided on the scraper 4, the first forming surface 501 is provided on the support slope 41 of the scraper 4, or the first forming surface 501 and the support slope 41 of the scraper 4 share a slope.

[0060] like Figure 3 As shown, the second molding part 6 includes a second molding surface 601, which is used to fit against the second surface of the heat dissipation tooth 2 that is opposite to the first surface. A second molding structure 61 is disposed on the second molding surface 601. The second molding structure 61 can be integrally formed with the second molding surface 601, or it can be disposed independently of the second molding surface 601 by means of snap-fit, plug-in, connector connection, bonding or welding.

[0061] In one example, the second forming structure 61 includes a plurality of second dies 611 and a plurality of second punches 612. The plurality of second dies 611 and the plurality of second punches 612 are alternately arranged in a first direction of the second forming surface 601. The first direction of the second forming surface 601 is, for example, the inclined direction of the second forming surface 601, i.e., referring to... Figure 3 The direction shown by the Z2 axis. In the extrusion fit between the first forming part 5 and the second forming part 6, the first die 511 and the second punch 612 are in a convex-concave fit, and the first punch 512 and the second die 611 are in a convex-concave fit.

[0062] Preferably, each first die 511 and each first punch 512 are arranged along the second direction of the first forming surface 501, and each second die 611 and each second punch 612 are arranged along the second direction of the second forming surface 601. This allows a straight airflow path to be formed on the surface of the heat dissipation teeth 2, reducing the resistance of hot airflow on the surface of the heat dissipation teeth 2. The second direction of the first forming surface 501 is, for example, the width direction of the first forming surface 501, i.e., referring to... Figure 2The direction shown by the Y2 axis, the second direction of the second forming surface 601, for example, is the width direction of the second forming surface 601, i.e., referring to... Figure 3 The direction indicated by the Y2 axis. Exemplarily, the first die 511 includes either an arcuate concave surface or a serrated concave surface, and the first punch 512 includes either an arcuate convex surface or a serrated convex surface. Correspondingly, the second die 611 includes either an arcuate concave surface or a serrated concave surface, and the second punch 612 includes either an arcuate convex surface or a serrated convex surface. In this embodiment, the serrations are, for example, triangular teeth, trapezoidal teeth, or flat teeth.

[0063] In other possible ways, such as Figure 2 and Figure 5 As shown, the first forming part 5 includes a first forming surface 501, which is used to fit against the first surface of the heat dissipation tooth 2. The first forming structure 51 includes a plurality of first dies 511 and a plurality of first punches 512. The plurality of first dies 511 and the plurality of first punches 512 are alternately arranged in a first direction of the first forming surface 501. The first direction is, for example, the inclined direction of the first forming surface 501, i.e., referring to... Figure 2 The direction indicated by the Z2 axis. The first die 511 includes an arcuate concave surface, and the first punch 512 includes an arcuate convex surface. Each first die 511 and each first punch 512 is disposed along a second direction of the first forming surface 501, the second direction of the first forming surface 501 being, for example, the width direction of the first forming surface 501, i.e., referring to... Figure 2 The direction shown by the Y2 axis. The second forming structure 61 includes a plurality of pressure rollers 8. In the state of extrusion engagement between the first forming part 5 and the second forming part 6, the plurality of pressure rollers 8 engage with a plurality of first dies 511. The plurality of pressure rollers 8 are arranged along the first direction of the first forming surface 501, and the pressure rollers 8 rotate while being extruded and engaged with the corresponding first dies 511. The gap between adjacent pressure rollers 8 engages with the first punch 512, thereby forming recesses 2111 and protrusions 2112 alternately arranged along the inclined direction of the first forming surface 501 on the surface of the heat dissipation teeth 2.

[0064] In some implementations, such as Figure 1 and Figure 5As shown, the processing apparatus includes a support 7, which provides support force for the extrusion fit between the first molding section 5 and the second molding section 6. In one example, when the first molding section 5 is positioned on the scraper 4, the support 7 supports the scraper 4 in the extrusion fit between the first molding section 5 and the second molding section 6. The support 7, for example, includes two movable first support blocks located on opposite sides of the substrate 3. After the first molding section 5 is bonded to the first surface, the two first support blocks move to the lower surface of the scraper 4 to support the scraper 4, thereby increasing the mechanical properties of the scraper 4 during the molding process of the heat dissipation teeth 2 by the first molding section 5 and the second molding section 6. In another example, such as... Figure 4 As shown, when the first molding part 5 and the scraper 4 are separately and independently arranged, the support part 7 is used to support the first molding part 5 under the extrusion fit between the first molding part 5 and the second molding part 6. The support part 7 includes, for example, two movable second support top blocks that can be located on opposite sides of the substrate 3. After the first molding part 5 is attached to the first surface, the two second support top blocks will move to the lower surface of the first molding part 5 to support the first molding part 5, thereby increasing the mechanical properties of the first molding part 5 during the molding process of the first molding part 5 and the second molding part 6 for the heat dissipation teeth 2.

[0065] According to an exemplary embodiment, a structural diagram of the toothed radiator obtained using the processing apparatus of this embodiment is shown below. Figure 6 and Figure 7 As shown, the toothed heat sink includes a substrate 1 and a plurality of heat dissipation teeth 2 fixed to the substrate 1. The plurality of heat dissipation teeth 2 are arranged parallel to each other and spaced apart along the extension direction of the substrate 1. Each heat dissipation tooth 2 includes at least one heat dissipation portion 21, and the heat dissipation portion 21 includes a first heat dissipation region 211. The first heat dissipation region 211 includes a plurality of recesses 2111 and a plurality of protrusions 2112. The plurality of recesses 2111 and the plurality of protrusions 2112 are alternately arranged in the height direction of the heat dissipation tooth 2, and each protrusion 2112 and each recess 2111 are arranged along the length direction of the heat dissipation tooth. The extension direction of the substrate 1 is referenced. Figure 6 and Figure 7 The direction shown by the X1 axis. The height direction of heat dissipation tooth 2 is referenced. Figure 6 and Figure 7 The direction shown by the Y1 axis is referenced to the length direction of the heat dissipation tooth 2. Figure 1 The direction indicated by the Z1 axis. The shovel-shaped radiator processed by the machining apparatus of this embodiment forms a straight airflow channel. This straight airflow channel effectively reduces the airflow resistance when hot air flows over the surface of the shovel-shaped radiator. The direction of the hot airflow is referenced... Figure 6 and Figure 7 The direction indicated by the black arrow in the middle.

[0066] Furthermore, such as Figure 6 and Figure 7As shown, the heat dissipation part 21 includes a second heat dissipation area 212. The first heat dissipation area 211 and the second heat dissipation area 212 are arranged along the height direction of the heat dissipation tooth 2. The second heat dissipation area 212 is close to the substrate 1 and connects the first heat dissipation area 211 to the substrate 1. The second heat dissipation area 212 is planar, which helps to improve the reliability of the connection between the first heat dissipation area 211 and the substrate 1, and at the same time solves the problem of internal stress or root damage caused by the non-straight roots of the heat dissipation tooth 2. By making the extension length of the first molding structure 51 along the first molding surface 501 in the first direction less than the height of the heat dissipation tooth 2, and the setting length of the second molding structure 61 along the inclined direction of the second molding surface 601 less than the height of the heat dissipation tooth 2, during the pressing and fitting process of the first molding part 5 and the second molding part 6, the area of ​​the heat dissipation tooth 2 near the substrate 3 will not be molded, thereby forming the second heat dissipation area 212.

[0067] Furthermore, such as Figure 7 As shown, the heat dissipation denticle includes multiple heat dissipation sections 21, which are arranged along the length of the heat dissipation denticle. Multiple first heat dissipation areas 211 corresponding to the multiple heat dissipation sections 21 are separately and independently arranged. In two adjacent heat dissipation sections 21, the protrusion 2112 of one heat dissipation section 21 corresponds to the concave portion 2111 of the other heat dissipation section 21. When hot air flows across the surface of the heat dissipation denticle 2, it first flows into the airflow passage formed by the concave portion 2111 of one heat dissipation section 21, and then into the airflow passage formed by the protrusion 2112 of the other heat dissipation section 21. The direction of the hot airflow is referenced... Figure 7 The direction is indicated by the black arrow in the middle. This embodiment effectively breaks the boundary layer on the surface of the heat dissipation tooth 2 by dividing the airflow path into multiple segments, thereby improving the convective heat transfer efficiency.

[0068] In this embodiment, after the heat dissipation teeth 2 are scraped out on the surface of the substrate 3 by the scraper 4, the heat dissipation teeth 2 are cut into multiple small heat dissipation teeth arranged along their length by the cutting tool. Then, the first concave die 511 and the first convex die 512 are alternately arranged with two kinds of first pressing parts 5 in opposite order along the height direction of the heat dissipation teeth 2 and alternately cooperate with the first surface of the multiple small heat dissipation teeth. At the same time, the second concave die 611 and the second convex die 612 are alternately arranged with two kinds of second pressing parts 6 in opposite order along the height direction of the heat dissipation teeth 2 and alternately cooperate with the second surface of the multiple small heat dissipation teeth that is opposite to the first surface. Then, the first pressing parts 5 and the corresponding second pressing parts 6 are pressed together, thereby forming two different patterns on the surface of two adjacent small heat dissipation teeth.
