[0049] Figure 1 Shows a schematic structural diagram of a heat exchanger, Figure 1The heat exchanger 100 therein includes a first header 110, a second header 120, a plurality of flat tubes 130 arranged in parallel, and a plurality of fins 140 disposed on the flat tubes 130. Figure 2 is Figure 1 a cross-sectional view of the flat tube 130 therein. One or more channels 131 are provided in each flat tube 130. The first header 110 and the second header 120 are of a hollow structure. The two ends of the plurality of flat tubes 130 are respectively communicated with the first header 110 and the second header 120, so that the two ends of the plurality of channels in each header 130 are respectively communicated with the first header 110 and the second header 120.

[0050] Figure 3 is Figure 1 a schematic diagram of the fin 140 therein. As Figure 3 shown, a plurality of grooves 141 are provided on the fin 140 at intervals along the arrangement direction of the plurality of flat tubes 130. The plurality of flat tubes 130 are inserted into the grooves 141 of the fin, and the fin and the flat tube can be fixedly connected by brazing or the like, or the fin and the flat tube can be brought into close contact by an expansion joint method. The plurality of fins on the outer peripheral surface of the flat tube can be arranged at equal intervals. A heat-conducting medium such as a refrigerant flows in from the first header 110 and flows out of the second header 120 after passing through the plurality of flat tubes 130; during the flow of the refrigerant, its heat is conducted from the surface of the flat tube 130 to the surface of the fin 140.

[0051] The fin 140 is usually made of a metal material with good thermal conductivity such as aluminum. And, in order to increase the heat dissipation area of the heat exchanger, the fin is usually set to be relatively thin. Louvers 144 for increasing air disturbance can be provided on the fin 140.

[0052] In some embodiments, continue to refer to Figure 3 , the fin 140 has opposite first surface 142 and second surface 143. A protrusion 145 is provided on the first surface 142, and the protrusion 145 is used to define the distance between two adjacent fins; when two identical fins 140 are installed on the flat tube 130, the protrusion 145 of one fin can abut against the second surface of the other fin, so as to form 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 fin 140 and the flat tube 130, the related art usually adopts the plug-in method. As an implementation, multiple fins can be arranged at a preset spacing, and then multiple flat tubes are sequentially inserted into the slots of the fins; then the flat tubes and each fin are fixed together by brazing, or the flat tubes and each fin can be made to be in close contact by expanding the tubes. In this manufacturing method, when inserting the flat tubes into the slots of multiple fins, due to the large friction force between the flat tubes and the fins, the problem of fin deformation may occur, thereby affecting the assembly effect. As another implementation, multiple flat tubes can also be arranged at a preset interval first, and then the fins are inserted one by one into the target assembly positions on the flat tubes; in this method, the fins to be installed cannot interfere with the fins that have already been installed on the flat tubes, so the spacing of the fins is restricted.

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

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

[0060] Figure 4 FIG. is a schematic structural diagram of a processing device provided by an embodiment of the present application. The processing device is used for processing a heat exchanger, and the heat exchanger includes a plurality of flat tubes and a plurality of fins. The plurality of flat tubes are arranged at intervals along their thickness directions, and the plurality of fins are arranged at intervals along the extending direction of the flat tubes. Each fin has a plurality of grooves, and the plurality of flat tubes respectively pass through the plurality of grooves of each fin. For the specific structure of the heat exchanger, reference can be made to Figures 1 - 3 , which will not be elaborated here.

[0061] Figure 4 The processing device 400 in

[0062] includes: a platform part 410 and a pusher 420.

[0063] Among them, the platform part 410 is used to place a plurality of flat tubes 130.

[0064] In some embodiments, a first fixing part 411 and a second fixing part 412 are provided on the platform part 410.

[0065] The first fixing part and the second fixing part are arranged at both ends of the platform part 410, and both ends of the flat tube 130 can be positioned and fixed through the first fixing part 411 and the second fixing part 412 respectively.

[0066] In some embodiments, a plurality of grooves are provided on both the first fixing part 411 and the second fixing part 412. The arrangement direction of the plurality of grooves is consistent with the width direction of the plurality of flat tubes 130, and the width of each groove is close to the thickness of the flat tube 130, so that the flat tube 130 can be placed in the groove to position it in the width direction, so as to ensure that the plurality of flat tubes 130 can be arranged at intervals along their thickness directions.

[0067] As an implementation manner, the frame part 430 may be Figure 4 the frame structure formed by welding metal square tubes shown in

[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, and the plurality mentioned here may be two or more than two; as an example, the number of the 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, in 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 fixed portion 411 on the platform portion 410 to the second fixed portion 412. The fin group 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 the embodiment of the present application, a plurality of push plates 421 are arranged on the pushing member 420, so that within the same pushing cycle, the plurality of push plates can respectively push a plurality of fin groups to move. Compared with the prior art in which a 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, Figure 5 As shown, Figure 5 yes Figure 4 The pusher 420 is a partially enlarged view of the pusher 421, wherein the pusher plate 421 includes a plurality of grooves 4211, which are arranged at intervals and are arranged correspondingly to the plurality of grooves on the fin.

[0072] In some embodiments, Figure 4 As shown, 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, a 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 also 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 figure) may be provided between the pushing member 420 and the frame portion 430 .

[0075] The connection mechanism 440 may include a linear slide rail 441 and a slider 442, wherein the linear slide rail 441 is fixed on 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, and 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 rail 441, the pusher 420 can be moved along the first direction.

[0076] The driving 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 the driving device, for example, it can be a linear motor, a cylinder, a hydraulic cylinder, or the driving device can also be a rotary motor, and the rotary motor and the gear rack structure are used to achieve the above reciprocating linear motion. The specific implementation method of the driving device is not limited in the embodiment of the present application.

[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, the loading mechanism is disposed at one end close to the first fixing portion 411 .

[0078] The feeding mechanism is used to provide the fin group to be installed, and between adjacent pushing cycles, the fin group to be installed is placed at a feeding position of a plurality of flat tubes, and the feeding position is arranged at the first end of the flat tube.

[0079] The pusher 420 is configured such that, in two consecutive pushing cycles, any two adjacent push plates among the plurality of push plates push the same fin group to move along the first direction in sequence. Figure 6 A detailed description is given. Figure 6 The steps of assembling a heat sink using the processing device in adjacent first pushing cycles and second pushing cycles are shown.

[0080] In step S610, Figure 6 As shown in (a), before the first pushing cycle, the loading mechanism places the first fin group at the loading position (i.e., the first position point L1 in the figure).

[0081] In step S620, if Figure 6 As shown in (b), the push member 420 moves along the first direction, and the first push plate 421A pushes the first fin set 510A to the second position point L2.

[0082] In step S630, if Figure 6 As shown in (c), after the first fin group is pushed to the second position point L2, the pusher retreats to the initial position in a direction away from the first direction. At this time, the loading mechanism places the second fin group at the first position point L1.

[0083] In step S640, as Figure 6 (d) shows, the pusher 420 moves in the first direction again. At this time, the first push plate 431A pushes the second fin group from the first position point L1 to the second position point L2, and at the same time, the second push plate 431B pushes the first fin group at the second position point L2 to the third position point L3.

[0084] During Figure 6 the process shown in (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 Figure 6 the pushing shown in (d), the pusher 420 returns to the initial position again and repeats the above feeding-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] Before pushing the first fin group 510A to the target installation position in multiple pushing cycles, the distances that the pusher moves in the first direction and retreats away from the first direction are both the first distance, and the distance between any two adjacent push plates among the multiple push plates is also the first distance, so that each fin group is pushed forward by the first distance within the same pushing cycle.

[0087] After pushing the first fin group to the target installation position, the states of the pusher and the radiator are as Figure 7 shown; it should be noted that Figure 6 and Figure 7 are both illustrated by taking the pusher as an example with 10 push plates included.

[0088] When the push plate is in the initial position, the positions on the flat tube corresponding to each push plate are the first position point L1 - the tenth position point L10, the target position of the first fin group is the eleventh position point L11, and the distance between adjacent position points is the above first distance D1. At this time, fin groups exist at the second position point L2 - the eleventh position point L11. After that, if the pushing is still carried out in the way described above, when the pusher pushes multiple fin groups forward, the second fin group at the tenth position point L10 will contact the first fin group that has been pushed in place. At this time, the distance that the pusher moves forward is the difference between the first distance D1 and the thickness d of the fin group. In this case, the distances that the other fin groups are pushed are also D1 - d, and these fin groups will not 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 respectively.

[0090] Method 1

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

[0092] At the radiator Figure 7 In the multiple pushing cycles after the state shown, the fin group at the farthest end will interfere with the fin group that has been pushed into place. Therefore, as an implementation method provided by the embodiment of the present application, the distance that the fin group at the farthest end is pushed 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 pushed distance of the first target fin group corresponding to the target push plate is set to D2, and the pushed distances of multiple fin groups other than the first target fin group 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 pushing 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 pushing 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 among 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 scheme will be described in more detail below 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 example of the pusher having 10 push plates as mentioned above, in the 10th push cycle, the radiator reaches Figure 7 In the state shown, the first fin group is pushed to the eleventh position point 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. To avoid interference with the first fin group, in the 11th pushing cycle, the distance that the second fin group is pushed forward is set to D2 = D1 - d - f; where d is the thickness of the fin group and f is the gap width between adjacent fin groups; the distances that the other fin groups are pushed are still D1.

[0099] After the 11th pushing cycle ends, the radiator reaches Figure 8 the state shown, and the second fin group moves forward a distance of D2 from the tenth position point, and the distance between it and the first fin group is f.

[0100] In the next pushing cycle (i.e., the 12th pushing cycle), as Figure 9 shown, the third fin group is the second target fin group. In this pushing cycle, the distance that the third fin group is pushed forward is set to D3 = D1 - 2d - 2f, and the distances that the other fin groups are pushed are D1. After the third fin group moves a distance of D3, it reaches its corresponding target position, 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 that the target fin group at the farthest end is pushed, the situation of interference between this fin group and the fin group that has been pushed in place is avoided.

[0102] In specific implementation, since the reciprocating movement distance of the pushing member in each cycle is the same. Therefore, in order to adjust the distance that the target fin group at the farthest end is pushed, the position of the target push plate can be adjusted; during pushing, the target push plate contacts the target fin group after moving a certain empty stroke, so that the distance that the target fin group is pushed can be shortened while the overall moving distance of the pushing member remains 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 plate of the target push plate is shortened by a fourth distance, and the fourth distance is the sum of the thickness of the fin group and the gap width between adjacent fin groups.

[0104] Also with Figure 8 and Figure 9For example, before the 11th push cycle, the 10th push plate is moved toward the 9th push plate by the fourth distance D4=d+f; at this time, 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; in the 11th push cycle, the 10th push plate moves the fourth distance D4 along the first direction and contacts the second fin group, and then pushes the second fin group forward, and 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 distances moved by the fin groups in the area are all the first distance D1, and after the 11th push 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, and it is moved the fourth distance D4 closer to the 9th push plate; when the pusher is in the 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 and then contacts the third fin group, and then pushes the third fin group to move; after the pusher moves 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 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 the target push plate and the adjacent push plate is shortened to less than or equal to the first distance threshold, an area at the farthest end of the flat tube is filled with the fin group; in this case, the push plate located at one end close to the target installation position among the multiple push plates needs to be removed; after removing the push plate, the farthest push plate is used as the new target push plate, and the above process is repeated until the adjacent area is filled. The above first distance threshold is the sum of the thickness of a single fin group and the gap width of adjacent fin groups.

[0108] Method 2

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

[0110] During the pushing cycle when the first fin group is pushed to the target installation position, the pusher retreats a fifth distance to a side away from the first direction after pushing the first fin group to the target installation position, and 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 pusher first moves the first distance along the first direction in 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 pushing member with 10 push plates 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 in 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 that each fin is pushed 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 push cycle, the status of the pusher and heat exchanger is as follows: Figure 10 As shown. 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. Each push plate will contact each fin group after moving a distance of d+f, and then push multiple fin groups to move respectively. Each fin group is pushed a distance of 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 completing the pushing, the pusher retreats the fifth distance D5. The state of the pusher and the heat exchanger after the 11th pushing cycle is as shown. Figure 11 shown.

[0116] In the 12th pushing cycle, the pushing member moves a first distance D1 in the first direction. Each push plate will contact each fin group after moving a distance of 2d + 2f, and then push multiple fins to move respectively. The distance that each fin group is pushed is D1 - 2d - 2f. The third fin group is pushed closer to the second fin group, and the distance between them is f. After the pushing is completed, the pushing member retracts a fifth distance D5 again. After the 12th pushing cycle, the states of the pushing member and the heat exchanger are as shown in Figure 12 shown

[0117] In each subsequent pushing cycle, the pushing member reciprocates between retraction and pushing in accordance with the above motion law. When one area among multiple areas on the flat tube is filled, for example, when the area between the tenth position point L10 and the eleventh position point L11 is filled, if feeding and pushing continue, there will be two fin groups existing simultaneously between the first position point L1 and the second position point L2, which will cause interference. In this case, it is necessary to reduce the feeding of the feeding structure once and perform feeding in a pushing cycle after this pushing cycle, so as to avoid interference between two fin groups in the same area.

[0118] It should be noted that the above 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.

[0119] As described above in combination with Figures 1 - 12 the device embodiments of the present application are introduced.
