[0049] Figure 1 shows a schematic structural diagram of a heat exchanger. The heat exchanger 100 in Figure 1 includes a first header 110, a second header 120, a plurality of parallel flat tubes 130, and a plurality of fins 140 extending through the flat tubes 130. Figure 2 is a cross-sectional view of the flat tubes 130 in Figure 1. Each flat tube 130 is provided with one or more channels 131. The first header 110 and the second header 120 are hollow structures. The ends of the plurality of flat tubes 130 are connected to the first header 110 and the second header 120, respectively, so that the ends of the plurality of channels in each header 130 are connected to the first header 110 and the second header 120, respectively.

[0050] Figure 3 is a schematic diagram of the fin 140 in Figure 1 . As shown in Figure 3 , the fin 140 is provided with multiple slots 141 spaced along the arrangement direction of the multiple flat tubes 130. The multiple flat tubes 130 are inserted into the slots 141 of the fin. The fins and the flat tubes can be fixedly connected by brazing or by expansion joints to achieve close contact between the fins and the flat tubes. The multiple fins on the outer circumference of the flat tubes can be arranged at equal intervals. A heat-conducting medium, such as a refrigerant, flows from the first manifold 110, passes through the multiple flat tubes 130, and then exits the second manifold 120. As the refrigerant flows, its heat is transferred from the surfaces of the flat tubes 130 to the surfaces of the fins 140.

[0051] The fins 140 are usually made of a metal material with good thermal conductivity, such as aluminum, and are usually thinner to increase the heat dissipation area of ​​the heat exchanger. The fins 140 may be provided with louvers 144 to increase air turbulence.

[0052] In some embodiments, referring to Figure 3 , the fin 140 has a first surface 142 and a second surface 143 relative to each other, and a protrusion 145 is provided on the first surface 142. The protrusion 145 is used to limit the distance between two adjacent fins. When two identical fins 140 are installed on the flat tube 130, the protrusion 145 of one of the fins can abut against the second surface of the other fin, thereby forming a gap between the two fins. At this time, the thickness of the gap between the two fins is the height of the protrusion 145.

[0053] When assembling the fins 140 and the flat tubes 130, the related art generally adopts a plug-in method. As an implementation method, multiple fins can be arranged at a preset spacing, and then multiple flat tubes can be sequentially inserted into the grooves of the fins; the flat tubes and the fins can be fixed together by brazing, or the flat tubes and the fins can be made to be in close contact with each other by expanding the tubes. In this manufacturing method, when the flat tubes are inserted into the grooves of the multiple fins, due to the large friction between the flat tubes and the fins, the fins may be deformed, thereby affecting the assembly effect. As another implementation method, multiple flat tubes can be arranged at preset intervals, and then the fins can be inserted one by one into the target assembly position on the flat tubes; in this method, the fins to be installed cannot interfere with the fins already installed on the flat tubes, so the spacing between the fins is restricted.

[0054] Therefore, how to improve assembly efficiency while ensuring assembly quality has become an urgent problem to be solved.

[0055] In view of the above problems, embodiments of the present application provide a heat exchanger processing device and method, a control method for the processing device, and a storage medium.

[0056] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0059] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0060] Figure 4 is a schematic structural diagram of a processing device provided in an embodiment of the present application. This processing device is used to process a heat exchanger. The heat exchanger includes multiple flat tubes and multiple fins. The multiple flat tubes are spaced apart along their thickness, and the multiple fins are spaced apart along the extension direction of the flat tubes. Each fin has multiple slots, and the multiple flat tubes pass through the multiple slots of each fin. The specific structure of the heat exchanger can be seen in Figures 1-3 and will not be repeated here.

[0061] The processing device 400 in FIG. 4 includes a platform portion 410 and a pushing member 420 .

[0062] The platform portion 410 is used to place a plurality of flat tubes 130 .

[0063] In some embodiments, a first fixing portion 411 and a second fixing portion 412 are provided on the platform portion 410 .

[0064] The first fixing portion and the second fixing portion are disposed at both ends of the platform portion 410 . Both ends of the flat tube 130 can be positioned and fixed by the first fixing portion 411 and the second fixing portion 412 , respectively.

[0065] In some embodiments, a plurality of grooves are provided on both the first fixing portion 411 and the second fixing portion 412. The arrangement direction of the plurality of grooves is consistent with the width direction of the plurality of flat tubes 130. The width of each groove is close to the thickness of the flat tube 130. Thus, the flat tube 130 can be placed in the groove to position it in the width direction, thereby ensuring that the plurality of flat tubes 130 can be spaced apart along their thickness direction.

[0066] In some embodiments, the processing device further includes a frame portion 430 , which can be used to support the platform portion and other components in the processing device 400 .

[0067] As an implementation manner, the frame portion 430 may be a frame structure formed by welding metal square tubes as shown in FIG. 4 .

[0068] The pusher 420 includes a plurality of push plates 421 arranged along the extension direction of the flat tube 130. It should be noted that the embodiment of the present application does not specifically limit the number of the plurality of push plates. The term "plurality" herein may be two or more. As an example, the number of push plates 421 may be 10 as shown in the figure.

[0069] The pusher 420 can move relative to the platform portion 410. Specifically, the pusher 420 can perform periodic reciprocating pushing along the extension direction of the flat tube 130. Specifically, within the same pushing cycle, the pusher first moves along the first direction. At this time, the multiple push plates 421 on the pusher 420 can respectively push the multiple fin groups to move along the first direction; after completing the pushing, the pusher retreats to the side away from the first direction; the above-mentioned first direction is defined as the direction from the first end of the flat tube to the second end of the flat tube, or in other words, the first direction can be defined as the direction from the first fixing portion 411 on the platform portion 410 to the second fixing portion 412. The fin group described in the embodiment of the present application includes one or more fins. The fins mentioned here can be the fins 140 described above. The specific structure of the fins has been described in detail above and will not be repeated here.

[0070] In an embodiment of the present application, multiple push plates 421 are arranged on the pushing member 420, so that within the same pushing cycle, the multiple push plates can respectively push multiple fin groups to move. Compared with the prior art in which one pushing member can only push one fin group within one pushing cycle, the processing device can greatly improve the production and processing efficiency of the heat exchanger.

[0071] In some embodiments, as shown in FIG5 , FIG5 is a partial enlarged view of the pusher 420 in FIG4 , the push plate 421 includes a plurality of grooves 4211 , which are arranged at intervals and correspond to the plurality of grooves on the fins.

[0072] In some embodiments, as shown in FIG. 4 , the pushing member 420 includes a base plate 422 , and the plurality of pushing plates 421 are disposed on the base plate 422 .

[0073] In some embodiments, the plurality of push plates 421 are movably connected to the base plate 422. Specifically, each push plate 421 is detachably connected to the base plate 422, and the position of each push plate 421 on the base plate 422 can be adjusted as needed.

[0074] In some embodiments, in order to enable the pushing member 420 to achieve the reciprocating motion, a connecting structure 440 and a driving device (not shown in the figures) may be provided between the pushing member 420 and the frame portion 430 .

[0075] The connecting mechanism 440 may include a linear slide 441 and a slider 442. The linear slide 441 is fixed to the frame portion 430, and the slider 442 is connected to the pusher 420. A support 423 is further provided between the base plate 422 and the slider. The support 423 extends downward from the side of the base plate 422 and is connected to the slider 442. When the slider 442 moves on the linear slide 441, the pusher 420 can be moved along the first direction.

[0076] The drive device is connected to the pusher 420 and is used to drive the pusher 420 to perform reciprocating linear motion along the first direction. There are many ways to implement this drive device, such as a linear motor, a pneumatic cylinder, or a hydraulic cylinder. Alternatively, the drive device can be a rotary motor that utilizes the coordination of a rotary motor and a rack and pinion structure to achieve the reciprocating linear motion. The embodiments of this application do not limit the specific implementation of this drive device.

[0077] In some embodiments, the processing device further includes a loading mechanism, which is disposed at one end of the platform portion, and more specifically, at one end close to the first fixing portion 411 .

[0078] The loading mechanism is used to provide fin groups to be installed, and between adjacent pushing cycles, the fin groups to be installed are placed at loading positions of a plurality of flat tubes, where the loading positions are arranged at first ends of the flat tubes.

[0079] The pusher 420 is configured such that, during two consecutive pushing cycles, any two adjacent pusher plates from the plurality of pusher plates sequentially push the same fin assembly along the first direction. This is described in detail below with reference to FIG6 , which illustrates the steps of assembling a heat sink using the processing device during the first and second consecutive pushing cycles.

[0080] In step S610 , as shown in FIG6( a ), before the first pushing cycle, the loading mechanism places the first fin group at the loading position (ie, the first position point L1 in the figure).

[0081] In step S620 , as shown in FIG6( b ), the pusher 420 moves along the first direction, and the first push plate 421A pushes the first fin assembly 510A to the second position L2 .

[0082] In step S630, as shown in FIG6(c), after pushing the first fin group to the second position point L2, the pushing member retreats to the initial position in a direction away from the first direction, and the loading mechanism places the second fin group at the first position point L1.

[0083] In step S640, as shown in Figure 6(d), the pushing member 420 moves in the first direction again. At this time, the first push plate 421A pushes the second fin group from the first position point L1 to the second position point L2, and the second push plate 421B pushes the first fin group at the second position point L2 to the third position point L3.

[0084] In the process shown in FIG. 6( a )-( d ), in two adjacent pushing cycles, the first fin group moves forward under the action of the first push plate 421A and the second push plate 421B, respectively.

[0085] After completing the pushing shown in Figure 6(d), the pushing member 420 returns to the initial position again and repeats the above-mentioned loading-pushing process until the first fin group 510A is pushed to the target installation position, which is close to the second end of the flat tube.

[0086] In multiple pushing cycles before pushing the first fin group 510A to the target installation position, the distance that the pushing member moves along the first direction and retreats away from the first direction is the first distance, and the distance between any two adjacent push plates in the multiple push plates is also the first distance, so that each fin group is pushed forward the first distance in the same pushing cycle.

[0087] After the first fin group is pushed to the target installation position, the status of the pushing member and the heat sink is shown in FIG7 ; it should be noted that FIG6 and FIG7 are both described using the example that the pushing member includes 10 push plates.

[0088] When the push plate is in its initial position, the position on the flat tube corresponding to each push plate is from the first position point L1 to the tenth position point L10, the target position of the first fin group is the eleventh position point L11, and the distance between adjacent positions is the first distance D1 mentioned above. At this time, there are fin groups at the second position point L2 to the eleventh position point L11. After this, if the pushing is still carried out in the manner described above, when the pushing member pushes multiple fin groups forward, the second fin group at the tenth position point L10 will come into contact with the first fin group that has been pushed into place. At this time, the distance the pushing member moves forward is the difference between the first distance D1 and the thickness d of the fin group. In this case, the distance pushed by the remaining fin groups is also D1-d, and these fin groups will not be able to reach the preset position points in this pushing cycle.

[0089] Therefore, after the first fin group is pushed to the target installation position, it is necessary to adjust the subsequent multiple pushing cycles so that each fin group can be pushed to the corresponding target position. The embodiment of the present application provides two methods, which are described below.

[0090] Method 1

[0091] In this embodiment, the pushing member maintains the same motion pattern in each cycle. That is, in the same pushing cycle, the pushing member first moves a first distance in a first direction, and then retreats the first distance to a side away from the first direction after completing the pushing.

[0092] During multiple pushing cycles after the radiator reaches the state shown in FIG7 , the fin group at the farthest end may interfere with the fin group that has already been pushed into place. Therefore, as an implementation provided by an embodiment of the present application, the pushing distance of the fin group at the farthest end can be adjusted.

[0093] Specifically, in the first pushing cycle among multiple pushing cycles after the first fin group is pushed to the target installation position, the distance the first target fin group corresponding to the target push plate is pushed is set to D2, and the distances the multiple fin groups other than the first target fin group are pushed are still the first distance D1.

[0094] In the second pushing cycle adjacent to the first pushing cycle, the above-mentioned first target fin group is pushed to its corresponding target position. At this time, the pushing distance of the second target fin group corresponding to the target push plate is adjusted, and the pushed distance of the second target fin group is set to the third distance D3. The third distance D3 is smaller than the second distance D2. The pushed distances of the remaining fin groups except the second target fin group are still the first distance D1.

[0095] The first pushing cycle and the second pushing cycle are any two adjacent pushing cycles in a plurality of pushing cycles after the first fin group is pushed to the target installation position, and the target push plate is the push plate close to one end of the target position.

[0096] The following describes this solution in more detail by taking the first pushing cycle, which is the first pushing cycle after the first fin group is pushed to the target installation position, as an example.

[0097] Still taking the above-mentioned pushing member with 10 pushing plates as an example, in the 10th pushing cycle, the radiator reaches the state shown in FIG. 7 , where the first fin group is pushed to the eleventh position L11 (ie, the target installation position corresponding to the first fin group).

[0098] At this time, the target push plate is the first push plate, and the first target fin group is the second fin group shown in the figure. In order to avoid interference with the first fin group, in the 11th pushing cycle, the distance the second fin group is pushed forward is set to D2 = D1-df; where d is the thickness of the fin group, and f is the gap width between adjacent fin groups; the distance the remaining fin groups are pushed is still D1.

[0099] After the 11th pushing cycle, the radiator reaches the state shown in FIG8 , and the second fin group moves forward from the tenth position point by a distance D2 , and the distance between the second fin group and the first fin group is f.

[0100] In the next pushing cycle (i.e., the 12th pushing cycle), as shown in Figure 9, the third fin group is the second target fin group. In this pushing cycle, the distance the third fin group is pushed forward is set to D3 = D1-2d-2f, and the distance the remaining fin groups are pushed is D1. The third fin group reaches its corresponding target position after moving a distance of D3, and the gap between it and the second fin group is f. At this time, the first fin group, the second fin group and the third fin group are all at their corresponding target positions.

[0101] According to the above technical solution, by adjusting the distance to which the farthest target fin group is pushed, interference between the fin group and the fin groups that have been pushed into place is avoided.

[0102] In a specific implementation, since the reciprocating distance of the pusher in each cycle is the same, the position of the target push plate can be adjusted to adjust the distance the farthest target fin group is pushed. During the pushing process, the target push plate moves for a period of idle travel before contacting the target fin group. This shortens the distance the target fin group is pushed while keeping the overall moving distance of the pusher unchanged.

[0103] In each pushing cycle after the first fin group is pushed to the target installation position, between adjacent pushing cycles, the distance between the target push plate and the adjacent push plates of the target push plate is shortened by a fourth distance, which is the sum of the thickness of the fin group and the gap width between adjacent fin groups.

[0104] Taking Figures 8 and 9 as an example, before the 11th pushing cycle, the 10th push plate is moved toward the 9th push plate by a fourth distance D4 = d + f. At this point, the second fin group is located at the tenth position point L10, and the distance between the 10th push plate and the tenth position point is D4. During the 11th pushing cycle, the 10th push plate moves the fourth distance D4 in the first direction and contacts the second fin group, pushing the second fin group forward. The distance moved by the second fin group is the difference between the first distance D1 and the fourth distance D4, that is, the distance moved forward by the second fin group from the tenth position point is D1 - df, and the distance between the second fin group and the first fin group is f. At the same time, the fin groups in the region all move the first distance D1. After the 11th pushing cycle, the third fin group moves to the tenth position point L10.

[0105] After the 11th pushing cycle, the position of the 10th push plate is adjusted again, moving it a fourth distance D4 closer to the 9th push plate. When the pusher is in its initial position, the distance between the 10th push plate and the tenth position point L10 is twice the fourth distance (i.e., 2d + 2f). In the 12th pushing cycle, the 10th push plate moves twice the fourth distance D4 (2d + 2f) in the first direction, then contacts the third fin group, pushing the third fin group to move. After the pusher has moved the first distance, the distance pushed by the third fin group is D1 - 2d - 2f, and the distance between the third fin group and the first fin group is now f.

[0106] After that, the distance between the farthest push plate and the adjacent push plate is continuously shortened between adjacent pushing cycles, so that when the pusher moves the same distance, the distance that the farthest target fin group is moved is gradually reduced.

[0107] In some embodiments, when the distance between a target push plate and an adjacent push plate is shortened to less than or equal to a first distance threshold, a region at the farthest end of the flat tube is completely filled with fins. In this case, the push plate located near the target installation location is removed from the plurality of push plates. After removing this push plate, the farthest push plate is used as the new target push plate, and the above process is repeated until the adjacent region is completely filled. The first distance threshold is the sum of the thickness of a single fin group and the gap width between adjacent fin groups.

[0108] Method 2

[0109] During multiple pushing cycles before a first fin group among the multiple fin groups is pushed to the target installation position, the pushing member first moves a first distance in the first direction within the same pushing cycle, and then retracts the first distance away from the first direction after completing the pushing, so that each fin group is pushed the first distance within the same pushing cycle. This step is the same as described above.

[0110] During the pushing cycle of the first fin group being pushed to the target installation position, after pushing the first fin group to the target installation position, the pushing member retreats a fifth distance to the side away from the first direction. The fifth distance is the sum of the first distance, the thickness of the fin group, and the gap width between adjacent fin groups.

[0111] In each pushing cycle after the first fin group is pushed to the target installation position, the pushing member first moves the first distance along the first direction within the same pushing cycle, and then retreats to the side away from the first direction by a fifth distance after completing the pushing.

[0112] Still taking the example of the 10 push plates on the pushing member mentioned in the previous article, in multiple pushing cycles (i.e., the 1st pushing cycle to the 9th pushing cycle) before the first fin group is pushed to the target installation position (i.e., the eleventh position point L11), the pushing member first moves a first distance along the first direction in the same pushing cycle, and then retreats a first distance to the side away from the first direction after completing the pushing. In these 9 pushing cycles, the distance pushed by each fin in the same pushing cycle is the first distance D1.

[0113] During the pushing cycle (i.e., the 10th pushing cycle) in which the first fin group is pushed to the target installation position, the pushing member moves a first distance to push the first fin group to the target installation position; thereafter, the pushing member retreats a fifth distance D5 to the side away from the first direction, and the fifth distance D5 is the sum of the first distance D1, the thickness d of the fin group, and the gap width f between adjacent fin groups, i.e., D5 = D1 + d + f.

[0114] In each subsequent pushing cycle, the pushing member first moves a first distance D1 along the first direction, and then retreats a fifth distance to a side away from the first direction after completing the pushing.

[0115] After the 10th pushing cycle, the state of the pusher and the heat exchanger is shown in Figure 10. The position of the pusher is offset by d+f from the initial position to the side away from the first direction; in the subsequent 11th pushing cycle, the loading mechanism loads the material at the first position point L1, and the pusher moves the first distance D1 along the first direction. After moving the distance d+f, each push plate will contact each fin group and then push multiple fin groups to move. The distance pushed by each fin group is D1-df. The second fin group is pushed close to the first fin group, and the distance between the second fin group and the first fin group is f. After the pushing is completed, the pusher retreats the fifth distance D5. The state of the pusher and the heat exchanger after the 11th pushing cycle is shown in Figure 11.

[0116] During the 12th pushing cycle, the pusher moves a first distance D1 in the first direction. Each push plate contacts each fin group after moving a distance of 2d + 2f. The pusher then pushes each of the fins separately, each fin group being pushed a distance D1 - 2d - 2f. The third fin group is pushed close to the second fin group, with the distance f between them. After the pushing cycle is complete, the pusher retreats again, a fifth distance D5. The state of the pusher and heat exchanger after the 12th pushing cycle is shown in Figure 12.

[0117] During each subsequent pushing cycle, the pusher follows the aforementioned motion pattern, performing a reciprocating motion of retraction and pushing. When one of the multiple areas on the flat tube is fully filled, for example, when the area between the tenth point L10 and the eleventh point L11 is fully filled, continuing to load and push will result in two fin groups being present between the first point L1 and the second point L2, which could interfere with each other. In this case, it is necessary to reduce the loading cycle of the loading mechanism and perform loading again in the next pushing cycle after the previous one to avoid interference between the two fin groups in the same area.

[0118] It should be noted that the first distance D1 is an integer multiple of the sum of the thickness d of the fin group and the gap f between adjacent fin groups.
