[0001] This application relates to the field of radiators, and in particular to a double-head riveted radiator, a processing apparatus for a double-head riveted radiator, and a processing method for a double-head riveted radiator. Background Technology

[0002] A radiator is a device used to help dissipate heat from equipment so that it can be used continuously in good condition.

[0003] The invention patent with authorization announcement number CN104661495B discloses an insert-type heat sink, comprising a substrate, heat sinks, a heat conduction layer, and sidewalls. The heat sinks are inserted into the substrate, the heat conduction layer is located inside the substrate, and the sidewalls are located on both sides of the heat sinks. The substrate has grooves, and fiber heat conduction tubes are installed in the grooves. The heat sinks are made of aluminum alloy, and the bottom of the heat sinks has a heat-absorbing base, which is inserted into the surface of the substrate after being rolled and formed. The substrate has a protective layer, which consists of a heat-resistant layer, a corrosion-resistant layer, and a wear-resistant layer from the inside out. The outermost wear-resistant layer of the substrate is a frosted layer.

[0004] Regarding the aforementioned technologies, the inventors believe that after prolonged use, the heat sink is installed on the substrate via a plug-in connection, which reduces the clamping force between the outer wall of the heat sink and the outer wall of the substrate, thereby reducing the connection stability between the heat sink and the substrate. Summary of the Invention

[0005] To improve the connection stability between the heat sink and the substrate, this application provides a double-head riveted heat sink, a processing apparatus for the double-head riveted heat sink, and a processing method for the same.

[0006] In the first aspect, the double-head riveted heat sink provided in this application adopts the following technical solution:

[0007] A double-headed riveted heat sink includes a first main board and multiple heat sinks. The outer wall of the first main board has multiple first insertion slots for accommodating the ends of the heat sinks. The outer wall of the first main board also has multiple first riveting extrusion slots. The inner wall of each of the first riveting extrusion slots has multiple heat dissipation slots. The multiple first riveting extrusion slots are located one-to-one between adjacent first insertion slots. When the ends of the multiple heat sinks are inserted into the multiple first insertion slots one-to-one, and the inner walls of the first riveting extrusion slots are deformed in a direction away from each other, the inner walls of the first insertion slots abut against the outer wall of the heat sinks to achieve fixation.

[0008] By adopting the above technical solution, workers embed the ends of multiple heat sinks one by one into multiple first insertion slots. The first riveting extrusion groove is located between adjacent first insertion slots, and the inner wall of the first riveting extrusion groove is squeezed. The inner wall of the first riveting extrusion groove is deformed under force, and the deformation of the inner wall of the first insertion slot is driven to press against the outer wall of the heat sink, thereby improving the connection stability between the first motherboard and the heat sink and increasing the service life of the double-headed riveting heat sink. At the same time, multiple heat dissipation grooves are opened on the inner wall of the first riveting extrusion groove, increasing the contact area between the first motherboard and the air, thereby improving the heat dissipation performance of the double-headed riveting heat sink.

[0009] Optionally, a second motherboard is also included. The outer wall of the second motherboard has a plurality of second insertion slots for accommodating the ends of heat sinks. The plurality of second insertion slots are oriented one-to-one towards the plurality of first insertion slots. The outer wall of the second motherboard has a plurality of second riveting and pressing grooves. The plurality of second riveting and pressing grooves are located one-to-one between adjacent second insertion slots. When the two ends of the plurality of heat sinks are embedded one-to-one into the plurality of second insertion slots and the plurality of first insertion slots, the outer wall of the heat sink abuts against the inner wall of the first insertion slot and the inner wall of the second insertion slot, thereby realizing the connection between the first motherboard, the second motherboard and the plurality of heat sinks.

[0010] By adopting the above technical solution, one end of each of the multiple heat sinks is embedded in a corresponding first insertion slot, thereby connecting the multiple heat sinks to the first motherboard. The other end of each of the multiple heat sinks is embedded in a corresponding second insertion slot, thereby connecting the multiple heat sinks, the first motherboard, and the second motherboard. The inner walls of the multiple first riveting grooves are compressed, causing them to deform under force and press against the outer wall of the heat sink, thus fixing the multiple heat sinks to the first motherboard. Then, the inner walls of the multiple second riveting grooves are compressed, causing them to deform under force and press against the outer wall of the heat sink, thus fixing the multiple heat sinks to the second motherboard. Both the first and second motherboards can accommodate heat-generating components, thereby increasing the installation area of ​​the double-headed riveted heat sink and making its structure more compact.

[0011] Secondly, the double-head riveting radiator processing device provided in this application adopts the following technical solution:

[0012] A processing device for double-head riveted radiators includes an upper template and a lower template. The upper template is slidably connected to the lower template, and the sliding direction of the upper template is towards or away from the lower template. A fixing frame is slidably connected to the lower template, and the sliding direction of the fixing frame is towards or away from the lower template. Multiple blades are connected to the fixing frame. When the multiple blades are embedded into multiple first riveting extrusion grooves one by one, the upper template slides towards the lower template, driving the blades to slide towards the lower template and extruding the inner wall of the first riveting extrusion groove. The inner wall of the first riveting extrusion groove deforms under force, which in turn causes the inner wall of the first insertion groove to deform and press against the outer wall of the radiator to achieve fixation.

[0013] By adopting the above technical solution, the worker places the double-headed riveting heat sink on the lower template, and multiple blades are embedded one-to-one into multiple first riveting extrusion grooves. The upper template slides towards the lower template, driving the blades to slide towards the lower template and extruding the inner wall of the first riveting extrusion groove. The inner wall of the first riveting extrusion groove is deformed by force, which in turn causes the inner wall of the adjacent first insertion groove to deform towards the heat sink. The inner wall of the first insertion groove presses against the inner wall of the heat sink, thus fixing the first motherboard and multiple heat sinks. This eliminates the need for the worker to use tools to sequentially embed into the inner walls of multiple first riveting extrusion grooves for processing, thereby improving the processing efficiency of fixing the first motherboard and multiple heat sinks.

[0014] Optionally, the end of the blade facing the lower template is provided with multiple guide blocks. When the multiple guide blocks are embedded into the multiple heat dissipation grooves one by one, the outer wall of the guide block abuts against the inner wall of the heat dissipation groove and drives the inner wall of the heat dissipation groove to deform.

[0015] By adopting the above technical solution, when multiple blades are embedded into multiple first riveting extrusion grooves one by one, multiple guide blocks face multiple heat dissipation grooves one by one, the upper template slides towards the lower template, the outer walls of multiple guide blocks abut against the inner walls of multiple heat dissipation grooves one by one, and drive the inner walls of the heat dissipation grooves to deform, increasing the contact area between the inner walls of the heat dissipation grooves and the air, thereby improving the heat dissipation effect of the double-head riveting heat sink; at the same time, it drives the inner walls of adjacent first insertion grooves to press against the outer walls of the heat sinks, further improving the connection stability of the first motherboard and multiple heat sinks.

[0016] Optionally, a drawer plate is provided on the lower template. The top surface of the drawer plate is used for placing the double-headed riveting radiator. The drawer plate is slidably connected to the lower template. The sliding direction of the drawer plate is towards or away from the blade. When the double-headed riveting radiator is placed on the top surface of the drawer plate, the drawer plate slides towards the blade. Multiple blades are embedded one-to-one into multiple first riveting extrusion grooves.

[0017] By adopting the above technical solution, the worker places the double-headed riveted radiator on the top surface of the drawer panel, with multiple blades facing the multiple first riveting extrusion grooves one by one. The drawer panel slides towards the blades, and the multiple blades are embedded into the multiple first riveting extrusion grooves one by one. This eliminates the need for the worker to align the multiple first riveting extrusion grooves with the multiple blades and embed them, thereby improving the worker's processing efficiency for the double-headed riveted radiator.

[0018] Optionally, a connecting frame is provided on the outer wall of the drawer panel, and the outer wall of the connecting frame is provided with multiple positioning grooves for the blades to pass through. The multiple positioning grooves are aligned with the multiple blades. When the double-headed riveting radiator is placed on the top surface of the drawer panel and the drawer panel is driven to slide towards the blades, the blade ends are sequentially passed through the first riveting extrusion groove and the positioning groove.

[0019] By adopting the above technical solution, the workers place the double-headed riveting radiator on the top surface of the drawer panel. Multiple blades are aligned with multiple first riveting extrusion grooves, and the drawer panel is driven to slide towards the blades. The blade ends are inserted into the first riveting extrusion grooves and positioning grooves, so that the two ends of the blades are limited to the fixed frame and connecting frame. When the upper template slides towards the lower template, the blades are driven to press against the inner wall of the first riveting extrusion grooves. The blades are not prone to deviation, so that the blades are subjected to uniform force on the inner wall of the first riveting extrusion grooves, thereby improving the stability of the blades in processing the inner wall of the first riveting extrusion grooves.

[0020] Optionally, the connecting frame is slidably connected to the drawer panel, and the sliding direction of the connecting frame is towards or away from the drawer panel. When the upper template slides towards the lower template, it drives the connecting frame to slide towards the lower template. The outer wall of the blade presses against the inner wall of the first riveting extrusion groove, and the inner wall of the first riveting extrusion groove deforms under force.

[0021] By adopting the above technical solution, when multiple blades are embedded into multiple first riveting extrusion grooves one by one, the two ends of the blades are limited to the fixed frame and the connecting frame. When the upper template slides towards the lower template, it drives the fixed frame and the connecting frame to slide towards the lower template, and drives the blades to press against the inner wall of the first riveting extrusion groove. The inner wall of the first riveting extrusion groove is deformed by force, which drives the inner wall of the first insertion groove to deform and press against the outer wall of the heat sink, thereby improving the pressing force between the heat sink and the first motherboard.

[0022] Optionally, a first elastic element is connected to the drawer panel, and the two ends of the first elastic element in the elastic direction are disposed on the drawer panel and the connecting frame. The first elastic element elastically drives the connecting frame to slide towards the upper template.

[0023] By adopting the above technical solution, when the blade finishes processing the inner wall of the first riveting extrusion groove, the upper template slides away from the lower template, so that the pressure of the upper template on the connecting frame disappears. The elastic force of the first elastic element drives the connecting frame to slide closer to the upper template, realizing the automatic reset of the connecting frame. There is no need for the operator to adjust the position of the connecting frame on the drawer plate, thereby speeding up the processing efficiency of the double-head riveted radiator.

[0024] Optionally, a second elastic element is provided on the lower template. The two ends of the second elastic element in the elastic direction are provided on the fixed frame and the lower template. The second elastic element elastically drives the fixed frame to slide towards the upper template.

[0025] By adopting the above technical solution, when the blade finishes processing the inner wall of the first riveting extrusion groove, the upper template slides away from the lower template, so that the pressure of the upper template on the fixed frame disappears. The elastic force of the second elastic element drives the fixed frame to slide closer to the upper template, realizing the automatic reset of the fixed frame. There is no need for the staff to adjust the position of the fixed frame on the drawer plate, thereby speeding up the processing efficiency of the double-head riveted radiator.

[0026] Thirdly, the processing method for a double-head riveted radiator provided in this application adopts the following technical solution:

[0027] A method for processing a double-head riveted radiator includes the following steps:

[0028] The first motherboard has multiple first insertion slots and multiple first riveting extrusion slots evenly spaced on it, with the multiple first riveting extrusion slots located between adjacent first insertion slots. The second motherboard has multiple second insertion slots and multiple second riveting extrusion slots evenly spaced on it, with the multiple second riveting extrusion slots located between adjacent second insertion slots.

[0029] Insertion plate, one end of multiple heat sinks is inserted into multiple first insertion slots in a corresponding manner, and the other end of multiple heat sinks is inserted into multiple second insertion slots in a corresponding manner.

[0030] The double-head riveted radiator is placed on the double-head riveted radiator processing device. The double-head riveted radiator processing device stamps the inner walls of the first riveting extrusion groove and the second riveting extrusion groove, driving the inner walls of the first insertion groove and the second insertion groove to press against the outer wall of the heat sink to achieve fixation.

[0031] By adopting the above technical solution, multiple heat sinks are embedded one-to-one into multiple first insertion slots at one end, and multiple heat sinks are embedded one-to-one into multiple second insertion slots at the other end, thereby connecting the first motherboard, the second motherboard, and the multiple heat sinks. Then, the double-headed riveting heat sink is placed on the double-headed riveting heat sink processing device, which presses the inner walls of multiple first riveting extrusion slots to force the inner walls of the first insertion slots to press against the outer walls of the heat sinks. Then, it presses the inner walls of multiple second riveting extrusion slots to force the inner walls of the first insertion slots to press against the outer walls of the heat sinks. This improves the firmness and stability of the first motherboard, the second motherboard, and the multiple heat sinks, and increases the service life of the double-headed riveting heat sink.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. The setting of the first riveting extrusion groove drives the inner wall of the first insertion groove to deform and press against the outer wall of the heat sink, thereby improving the connection stability between the first motherboard and the heat sink and increasing the service life of the double-head riveted heat sink;

[0041] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0042] This application discloses a double-headed riveted heat sink. (Refer to...) Figure 1 A dual-head riveted heat sink includes a first motherboard 1, a second motherboard 2, and multiple heat sinks 3. The outer wall of the first motherboard 1 is provided with multiple first insertion slots 11 spaced apart, and the outer wall of the second motherboard 2 is provided with multiple second insertion slots 21 spaced apart. The multiple second insertion slots 21 are aligned with the multiple first insertion slots 11. One end of each of the multiple heat sinks 3 is embedded in the multiple first insertion slots 11, and the other end of each of the multiple heat sinks 3 is embedded in the multiple second insertion slots 21, thereby realizing the connection between the first motherboard 1, the second motherboard 2, and the multiple heat sinks 3.

[0043] Reference Figure 1 The outer wall of the first motherboard 1 is provided with a plurality of first riveting extrusion grooves 12 spaced apart. The plurality of first riveting extrusion grooves 12 are located one-to-one between adjacent first insertion grooves 11. The inner wall of the first riveting extrusion groove 12 is extruded and deformed laterally toward the adjacent first insertion groove 11, thereby driving the inner wall of the first insertion groove 11 to deform and press against the outer wall of the heat sink 3, thereby fixing the first motherboard 1 and the plurality of heat sinks 3.

[0044] Reference Figure 1 The outer wall of the second motherboard 2 is provided with a plurality of second riveting extrusion grooves 22 spaced apart. The plurality of second riveting extrusion grooves 22 are located one-to-one between adjacent second insertion grooves 21, and the plurality of second riveting extrusion grooves 22 are connected one-to-one with a plurality of first riveting extrusion grooves 12. The inner wall of the second riveting extrusion groove 22 is extruded, and the inner wall of the second riveting extrusion groove 22 is laterally deformed in the direction closer to the adjacent second insertion groove 21, which drives the inner wall of the second insertion groove 21 to deform and press against the outer wall of the heat sink 3, thereby fixing the second motherboard 2 and the plurality of heat sinks 3.

[0045] Reference Figure 1The outer walls of the first motherboard 1 and the second motherboard 2, which are away from the heat sink 3, are used for the installation of heat-generating components. Multiple heat dissipation grooves 13 are evenly spaced on the inner walls of the multiple first riveting extrusion grooves 12, which increases the contact area between the first motherboard 1 and the air, thereby improving the heat dissipation performance of the double-headed riveting heat sink.

[0046] The implementation principle of a double-headed riveted heat sink according to an embodiment of this application is as follows: one end of each of the multiple heat sinks 3 is embedded into a plurality of first insertion slots 11, and the other end of each of the multiple heat sinks 3 is embedded into a plurality of second insertion slots 21, thereby connecting the first motherboard 1, the second motherboard 2, and the multiple heat sinks 3. The inner wall of the first riveting extrusion groove 12 is squeezed, and the inner wall of the first riveting extrusion groove 12 deforms laterally toward the adjacent first insertion slot 11, causing the inner wall of the first insertion slot 11 to deform and press against the outer wall of the heat sink 3, thereby fixing the first motherboard 1 and the multiple heat sinks 3. Then the inner wall of the second riveting extrusion groove 22 is squeezed, and the inner wall of the second riveting extrusion groove 22 deforms laterally toward the adjacent second insertion slot 21, causing the inner wall of the second insertion slot 21 to deform and press against the outer wall of the heat sink 3, thereby fixing the second motherboard 2 and the multiple heat sinks 3, improving the connection stability between the first motherboard 1, the second motherboard 2, and the multiple heat sinks 3, thereby increasing the service life of the double-headed riveted heat sink.

[0047] Meanwhile, multiple heat dissipation slots 13 are spaced apart on the inner wall of the first riveting extrusion slot 12, increasing the contact area between the first motherboard 1 and the air, thereby improving the heat dissipation performance of the double-headed riveting heat sink.

[0048] This application also discloses a processing apparatus for double-head riveting radiators. (Refer to...) Figure 2 A double-head riveting radiator processing device includes an upper template 4 and a lower template 5. Four columns 6 are welded and fixed on the top surface of the lower template 5. The four columns 6 are located at the four corners of the lower template 5. Four connecting holes 41 are opened on the top surface of the upper template 4. The four connecting holes 41 are located at the four corners of the upper template 4. The axes of the four connecting holes 41 are parallel to the axes of the columns 6. The four connecting holes 41 penetrate the outer wall of the upper template 4. The four columns 6 are oriented one-to-one with the four connecting holes 41. The columns 6 are slidably connected to the inner wall of the connecting holes 41.

[0049] Reference Figure 2 The outer wall of the column 6 is coaxially fitted with a sliding sleeve 7. The material of the sliding sleeve 7 can be rubber or silicone. In this embodiment, the material of the sliding sleeve 7 is rubber, which has a certain deformation capability. When the upper template 4 slides along the axis of the column 6 toward the direction closer to the lower template 5, the outer wall of the sliding sleeve 7 abuts against the outer wall of the upper template 4 and drives the upper template 4 to slide away from the lower template 5.

[0050] Reference Figure 3A fixing frame 8 is connected to the lower template 5. Two positioning rods 9 are welded and fixed to the outer wall of the lower template 5. The axes of the two positioning rods 9 are parallel to the axis of the column 6. The fixing frame 8 has two sliding holes facing the outer wall of the lower template 5. The axes of the sliding holes are parallel to the axes of the positioning rods 9. The two positioning rods 9 face the two sliding holes one-to-one.

The two second elastic elements 10 are sleeved on the outer wall of the positioning rod 9 in a one-to-one correspondence. The elastic force direction of the second elastic elements 10 is parallel to the axis of the positioning rod 9. The two ends of the elastic force direction of the second elastic elements 10 are used to abut against the outer wall of the fixing frame 8 and the outer wall of the lower template 5. The elastic force of the second elastic elements 10 drives the fixing frame 8 to slide away from the lower template 5.

[0052] Reference Figure 3 The mounting bracket 8 is connected to multiple blades 14. The outer wall of the mounting bracket 8 has multiple mounting slots 81. The multiple blades 14 are embedded into the mounting slots 81 one by one. The outer wall of the blades 14 abuts against the inner wall of the mounting slot 81, realizing the initial installation of the mounting bracket 8 and the multiple blades 14. The mounting bracket 8 is connected to two fixing bolts 15. The two fixing bolts 15 pass through the outer wall of the mounting bracket 8 and the multiple blades 14 in sequence, so that the blades 14 are not easy to shift in the inner wall of the mounting slot 81, thereby improving the connection stability of the multiple blades 14 and the mounting bracket 8.

[0053] Reference Figure 3 Multiple guide blocks 16 are welded and fixed at intervals on the outer wall of the lower template 5 facing the blade 14. The arrangement direction of the multiple guide blocks 16 is the same as the length direction of the blade 14.

[0054] Reference Figure 3 A drawer plate 17 is connected to the lower template 5. The drawer plate 17 includes an upper plate 171 and a lower plate 172. The upper plate 171 is welded and fixed to the end face of the lower plate 172. The top surface of the upper plate 171 facing the upper template 4 is used for placing the double-headed riveted radiator. The lower plate 172 is slidably connected to the lower template 5. The lower plate 172 drives the upper plate 171 to move closer to or away from the blade 14.

[0055] Reference Figure 1 and Figure 3When the double-headed riveting heat sink is placed on the top surface of the upper plate 171, multiple blades 14 are aligned with multiple first riveting extrusion grooves 12, and the lower plate 172 slides towards the blades 14, causing the double-headed riveting heat sink to slide towards the multiple blades 14. Multiple blades 14 are embedded into multiple first riveting extrusion grooves 12, and multiple guide blocks 16 are aligned with multiple heat sink grooves 13.

[0056] Reference Figure 3 The top surface of the lower template 5 is connected to two positioning plates 18. The two positioning plates 18 are located on both sides of the lower plate 172, and the outer walls of the two positioning plates 18 and the side walls of the lower plate 172 slide in contact with each other. The length direction of the positioning plates 18 and the sliding direction of the lower plate 172 are parallel to each other.

[0057] Reference Figure 3 The top surface of the lower plate 172 is connected to a connecting frame 19. Two guide rods 20 are welded and fixed to the top surface of the lower plate 172. The axes of the two guide rods 20 are parallel to the axis of the positioning rod 9. The connecting frame 19 has two sliding holes on the top surface of the lower plate 172. The axes of the sliding holes are parallel to the axes of the guide rods 20. The two guide rods 20 are slidably connected to the inner walls of the two sliding holes one by one.

[0058] Reference Figure 3 The lower plate 172 is connected to two first elastic elements 23. The first elastic elements 23 can be torsion springs or compression springs. In this embodiment, the first elastic element 23 is a compression spring with a certain deformation capability. The two first elastic elements 23 are connected to two guide rods 20 one by one. The elastic force direction of the first elastic element 23 is parallel to the axis of the guide rod 20. The two ends of the elastic force direction of the first elastic element 23 abut against the outer wall of the connecting frame 19 and the outer wall of the lower plate 172 one by one. The elastic force of the first elastic element 23 drives the connecting frame 19 to slide away from the lower plate 172.

[0059] Reference Figure 3 Two limiting posts 24 are welded and fixed to the top surface of the lower plate 172. The axes of the two limiting posts 24 are parallel to the axis of the guide rod 20. Two limiting holes are opened on the outer wall of the connecting frame 19. The axes of the two limiting holes are parallel to the axis of the guide rod 20. The limiting holes penetrate the outer wall of the connecting frame 19. The two guide rods 20 are slidably connected to the inner walls of the two limiting holes. The ends of the guide rods 20 away from the lower plate 172 are threaded with nuts. When the two guide rods 20 are threaded through the two limiting holes, the nuts are threaded to the ends of the guide rods 20. The connecting frame 19 slides up and down along the axis of the guide rods 20, making it difficult for the connecting frame 19 to detach from the guide rods 20, thereby improving the connection stability between the connecting frame 19 and the guide rods 20.

[0060] Reference Figure 3The outer wall of the connecting frame 19 has multiple positioning grooves 191, each corresponding to one of the multiple blades 14. The outer wall of the connecting frame 19 facing the upper plate 171 is used to abut against the outer wall of the double-headed riveted radiator. A handle 25 is connected to the outer wall of the lower plate 172 away from the blades 14. The handle 25 is fixed to the lower plate 172 by bolts. An abutment block 26 is welded to the end of the handle 25 facing the lower template 5. The end of the abutment block 26 away from the handle 25 protrudes from the bottom wall of the lower plate 172.

[0061] Reference Figure 1 and Figure 3 When the double-headed riveting radiator is placed on the upper plate 171, multiple blades 14 are aligned with multiple first riveting extrusion grooves 12, and multiple first riveting extrusion grooves 12 are aligned with multiple positioning grooves 191. The lower plate 172 slides towards the blades 14, causing the double-headed riveting radiator to slide towards the blades 14. The ends of the blades 14 away from the fixing frame 8 are sequentially connected to the first riveting extrusion grooves 12 and positioning grooves 191. The outer wall of the blades 14 away from the fixing frame 8 and the outer wall of the connecting frame 19 away from the fixing frame 8 are flush. At the same time, the outer wall of the abutment block 26 abuts against the side wall of the lower template 5 and limits the sliding of the lower plate 172 on the top surface of the lower template 5.

[0062] Reference Figure 3 and Figure 4 The upper template 4 is connected to the outer wall of the lower template 5 by two stamping blocks 27. The two stamping blocks 27 are fixed to the upper template 4 by bolts. When the lower plate 172 slides towards the blade 14 and abuts the outer wall of the abutting block 26 against the side wall of the lower template 5, the two stamping blocks 27 face the fixing frame 8 and the connecting frame 19 respectively.

[0063] Reference Figure 3 and Figure 4 Two pusher blocks 28 are connected to the outer wall of the upper template 4 facing the lower template 5. The two pusher blocks 28 are connected to the outer wall of the blade 14 with elastic blocks 29. The elastic blocks 29 facing the outer wall of the blade 14 are used to press the outer wall of the double-head riveted radiator. The material of the elastic blocks 29 can be rubber or cowhide. In this embodiment, the material of the elastic blocks 29 is cowhide, which has a certain deformation ability.

[0064] The implementation principle of the double-head riveting radiator processing device in this application embodiment is as follows: The operator places the double-head riveting radiator on the upper plate 171, with multiple blades 14 facing the multiple first riveting extrusion grooves 12 one-to-one, and the multiple first riveting extrusion grooves 12 facing the multiple positioning grooves 191 one-to-one. The operator holds the handle 25 and drives the lower plate 172 to slide towards the blades 14. The outer wall of the abutment block 26 abuts against the side wall of the lower template 5. The blades 14 sequentially pass through the first riveting extrusion grooves 12 and the positioning grooves 191, and the end face of the blades 14 is flush with the side wall of the connecting frame 19. The connection between multiple blades 14 and the double-headed riveting heat sink is then achieved. The upper template 4 is then driven to slide towards the lower template 5, and the two stamping blocks 27 are pressed against the outer wall of the fixing frame 8 and the outer wall of the connecting frame 19 respectively. The stamping blocks 27 drive the fixing frame 8 and the connecting frame 19 to slide towards the lower template 5, thereby causing the blades 14 to press against the inner wall of the first riveting extrusion groove 12. The inner wall of the first riveting extrusion groove 12 is subjected to force and deforms laterally towards the adjacent first insertion groove 11, thereby driving the inner wall of the first riveting extrusion groove 12 to press against the outer wall of the heat sink 3, thus achieving the fixation of the first main board 1 and multiple heat sinks 3.

[0065] Then flip the double-headed riveted heat sink over and place it on the upper plate 171. Repeat the above steps to fix the second motherboard 2 and multiple heat sinks 3, improve the connection stability between the first motherboard 1, the second motherboard 2 and multiple heat sinks 3, and increase the service life of the double-headed riveted heat sink.

[0066] This application also discloses a method for processing a double-headed riveted radiator, including the following steps:

[0067] The first motherboard 1 is provided with a plurality of first insertion slots 11 and a plurality of first riveting extrusion slots 12 spaced apart by a milling machine. The plurality of first riveting extrusion slots 12 are located one-to-one between adjacent first insertion slots 11. A plurality of heat dissipation slots 13 are spaced apart on the inner wall of the first riveting extrusion slots 12.

[0068] The second motherboard 2 is provided with a plurality of second insertion slots 21 and a plurality of second riveting extrusion slots 22 spaced apart by a milling machine. The plurality of second riveting extrusion slots 22 are located one-to-one between adjacent second insertion slots 21, and the plurality of second insertion slots 21 face one-to-one toward the plurality of first insertion slots 11.

[0069] One end of each heat sink 3 is inserted into one of the first insertion slots 11, and the outer wall of the heat sink 3 abuts against the inner wall of the first insertion slot 11, thereby connecting the first motherboard 1 and the heat sink 3. The other end of each heat sink 3 is inserted into one of the second insertion slots 21, and the outer wall of the heat sink 3 abuts against the inner wall of the second insertion slot 21, thereby achieving the initial installation of the double-head riveted heat sink.

[0070] The double-head riveted heat sink is placed on the double-head riveted heat sink processing device. Multiple blades 14 are embedded into multiple first riveting extrusion grooves 12 in a corresponding manner. The upper template 4 slides towards the lower template 5. The blades 14 punch the inner wall of the first riveting extrusion groove 12. The inner wall of the first riveting extrusion groove 12 deforms towards the adjacent first insertion groove 11, causing the inner wall of the first insertion groove 11 to deform and press against the outer wall of the heat sink 3, thereby fixing the first motherboard 1 and multiple heat sinks 3.

[0071] Take out the double-headed riveting heat sink and flip it over to place it on the double-headed heat sink processing device. Multiple blades 14 are embedded into multiple second riveting extrusion grooves 22 one by one. The upper template 4 slides towards the lower template 5. The blades 14 press the inner wall of the second riveting extrusion groove 22. The inner wall of the second riveting extrusion groove 22 deforms towards the adjacent second insertion groove 21, driving the inner wall of the second insertion groove 21 to deform and press against the outer wall of the heat sink 3, thereby fixing the second motherboard 2 and multiple heat sinks 3.

[0072] The implementation principle of the double-head riveted heat sink processing method in this application embodiment is as follows: one end of multiple heat sinks 3 is embedded into multiple first insertion slots 11, and the other end of multiple heat sinks 3 is embedded into multiple second insertion slots 21. Then, the inner walls of multiple first riveting extrusion slots 12 and multiple second riveting extrusion slots 22 are punched by the double-head riveted heat sink processing device, so that the inner walls of the first insertion slots 11 and the second insertion slots 21 are pressed against the outer wall of the heat sink 3, thereby improving the connection stability of the first motherboard 1, the second motherboard 2 and the multiple heat sinks 3, and increasing the service life of the double-head riveted heat sink.

[0073] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
