[0002] This application claims priority and benefits to Chinese patent application number 202410185883.1, filed on February 19, 2024, and priority and benefits to Chinese patent application number 202410693243.1, filed on May 30, 2024. The entire contents of the above-mentioned Chinese patent applications are hereby incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of heat exchange technology, and in particular, to a heat exchanger processing device and a heat exchanger processing method. Background Art

[0004] Heat exchangers are currently widely used in heat exchange systems. In related technologies, when assembling a heat exchanger, the heat exchange tubes need to be inserted into the fin holes to achieve the connection between the heat exchange tubes and the fins. However, due to the structural characteristics of the fins and heat exchange tubes, the thin fins are stacked together, while the heat exchange tubes are long. This can lead to problems such as tube tilting and jamming when inserting the heat exchange tubes, resulting in a very low yield rate for tube insertion. Summary of the Invention

[0005] The present application provides a heat exchanger processing device and a heat exchanger processing method, which improve the yield rate of heat exchange tubes penetrating into fins and improve the processing efficiency of the heat exchanger.

[0006] In one aspect, an embodiment of the present application provides a heat exchanger processing device, comprising:

[0007] a first receiving portion;

[0008] a second accommodating portion, wherein the width direction of the second accommodating portion is defined as a first direction, the length direction of the second accommodating portion is defined as a second direction, and the height direction of the second accommodating portion is defined as a third direction; the first accommodating portion is located on one side of the second accommodating portion along the second direction; there are a plurality of second accommodating portions, and the plurality of second accommodating portions are spaced apart along the first direction;

[0009] a limiting portion, at least a portion of which protrudes from the first accommodating portion in the third direction, the limiting portion comprising a first limiting member and a second limiting member, the first limiting member being located on one side of the first accommodating portion in the second direction, the second limiting member and the first limiting member being arranged opposite to each other along the second direction, the first limiting member comprising a plurality of first comb-tooth portions, a first groove being defined between two adjacent first comb-tooth portions, the second accommodating portion being closer to the first limiting member relative to the second limiting member, and the second accommodating portion and the first groove being arranged correspondingly in the second direction;

[0010] The pushing portion is at least partially located in the second accommodating portion, and the pushing portion is capable of moving along the second direction.

[0011] The first accommodating portion of the heat exchanger processing device is capable of accommodating fins, and the second accommodating portion is capable of accommodating heat exchange tubes. The limiting portion protrudes from the first accommodating portion in the third direction. The limiting portion includes a first limiting member and a second limiting member arranged opposite to each other in the second direction. The limiting portion can limit the fin in the second direction to reduce the position change of the fin during the insertion of the heat exchange tube. When the heat exchanger processing device is in operation, the pushing portion drives the heat exchange tubes located in the second accommodating portion to move along the second direction. The first accommodating portion is located on one side of the second accommodating portion along the second direction, pushing multiple heat exchange tubes into the first holes of the multiple fins. The second accommodating portion is adjacent to the first limiting member. When the heat exchange tubes located in the second accommodating portion move along the second direction, they first pass through the first groove of the first limiting member. The second accommodating portion and the first groove are arranged correspondingly in the second direction, so that the multiple heat exchange tubes can be aligned with the positions of the first holes of the fins to be inserted, thereby improving the position accuracy of the heat exchange tubes when inserting into the first holes of the fins, reducing the problems of the heat exchange tubes being stuck or tilted during the insertion process, thereby improving the yield rate of the heat exchange tubes inserting into the fins and improving the processing efficiency of the heat exchanger.

[0012] Another aspect of the present invention provides a heat exchanger processing method, including:

[0013] Placing a fin in the first receiving portion, wherein the fin includes a plurality of first holes, and the fin is in plurality, and the plurality of fins are spaced apart along a thickness direction of the fin;

[0014] Limiting the fin in the thickness direction of the fin;

[0015] Place the heat exchange tube into the second accommodating portion, wherein the length direction of the second accommodating portion is parallel to the thickness direction of the fin;

[0016] The heat exchange tube is driven to move along the thickness direction of the fin, and the heat exchange tube first passes through the first groove and then passes through the first holes of the plurality of fins. The first groove and the second accommodating portion are correspondingly arranged in the second direction, and the first groove and the first hole are correspondingly arranged in the second direction.

[0017] The heat exchanger processing method places the fin in the first accommodating part, limits the fin in the thickness direction of the fin, and places the heat exchange tube in the second accommodating part. The length direction of the second accommodating part is parallel to the thickness direction of the fin, and the heat exchange tube in the second accommodating part is driven to move along the thickness direction of the fin, so that multiple heat exchange tubes pass through the first holes of multiple fins. When the heat exchange tube moves along the thickness direction of the fin, it first passes through the first groove and then passes through the first hole of the fin. The first groove and the second accommodating part are correspondingly arranged, and the first groove and the first hole are correspondingly arranged, so that the heat exchange tube can be aligned with the position of the first hole of the fin to be penetrated, thereby improving the position accuracy of the heat exchange tube when penetrating the fin, reducing the problems of heat exchanger jamming and pushing when the heat exchange tube passes through the fin, improving the yield rate of heat exchange tube passing through the fin, and improving the processing efficiency of the heat exchanger.

[0041] A heat exchanger processing device according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0042] As shown in FIG. 1 to FIG. 15 , the heat exchanger processing device 100 according to the embodiment of the present invention includes: a first accommodating portion 11 , and the first accommodating portion 11 is used to place the fins 3 of the heat exchanger.

[0043] The first portion 22 includes a second accommodating portion 21. The width of the second accommodating portion 21 is defined as the first direction, the length of the second accommodating portion 21 is defined as the second direction, and the height of the second accommodating portion 21 is defined as the third direction. The first accommodating portion 11 is located on one side of the second accommodating portion 21 along the second direction. There are multiple second accommodating portions 21, and the multiple second accommodating portions 21 are arranged at intervals along the first direction. For ease of understanding, the first direction is the x-direction in the illustration, the second direction is the y-direction in the illustration, and the third direction is the z-direction in the illustration. The first, second, and third directions are substantially perpendicular. The width of the second accommodating portion 21 is the x-direction in the illustration, which is also the left-right direction in FIG. 3 , and the length of the second accommodating portion 21 is the y-direction in the illustration, which is also the up-down direction in FIG. 3 .

[0044] The limiting portion 12, at least a portion of the limiting portion 12 protrudes from the first accommodating portion 11 in the third direction, the limiting portion 12 includes a first limiting member 121 and a second limiting member 122, the first limiting member 121 is located on one side of the first accommodating portion 11 in the second direction, the second limiting member 122 and the first limiting member 121 are arranged opposite to each other along the second direction, the first limiting member 121 includes a plurality of first comb-tooth portions 1211, and a first groove 1212 is defined between two adjacent first comb-tooth portions 1211. The second accommodating portion 21 is closer to the first limiting member 121 relative to the second limiting member 122, and the second accommodating portion 21 and the first groove 1212 are arranged correspondingly in the second direction;

[0045] The pushing portion 24 , at least a portion of the pushing portion 24 is located in the second accommodation portion 21 , and the pushing portion 24 is capable of moving along the second direction.

[0046] The first accommodating portion 11 of the heat exchanger processing device 100 is used to place the fin 3, and at least part of the limiting portion 12 protrudes from the first accommodating portion 11 in the third direction. The limiting portion 12 includes a first limiting member 121 and a second limiting member 122. At least part of the first limiting member 121 protrudes from the first accommodating portion 11 in the third direction, and at least part of the second limiting member 122 protrudes from the first accommodating portion 11 in the third direction. The first limiting member 121 is located on one side of the first accommodating portion 11 in the second direction, and the second limiting member 122 and the first limiting member 121 are arranged relative to each other along the second direction. The second limiting member 122 can be located on the other side of the first accommodating portion 11 in the second direction. Therefore, the limiting portion 12 can limit the fin 3 placed on the first accommodating portion 11 in the second direction, thereby reducing the jamming and pushing problems caused by the change of the fin position during the process of the heat exchange tube 4 passing through the fin 3, and improving the finished product rate of the heat exchange tube 4 passing through the fin 3.

[0047] To better understand the heat exchanger processing device, the heat exchanger processing device 100 may include a first component 1 for placing the fins 3 and a second component 2 for initially placing the heat exchange tubes 4. The first component 1 includes a first receiving portion 11 and a limiting portion 12. The second component 2 includes a second receiving portion 21 and a pushing portion 24. The second component 2 is located on one side of the first component 1 in the second direction. The first component 1 and the second component 2 can be separate structures or an integrated structure. The heat exchanger processing device 100 may also include a base 10, which supports the heat exchanger processing device 100 and facilitates operation when processing the heat exchanger. The first receiving portion 11 and the second receiving portion 21 are located on the base 10.

[0048] The second component 2 of the heat exchanger processing apparatus 100 includes a second accommodating portion 21, which can accommodate a heat exchange tube 4. As shown in FIG5 , the length of the second accommodating portion 21 extends along the second direction. There are multiple second accommodating portions 21, which are spaced apart along the first direction, with one heat exchange tube 4 being accommodated in each second accommodating portion 21. Optionally, the second accommodating portion 21 may be a through-slot structure, with the length of the through-slot extending along the second direction.

[0049] The second component 2 of the heat exchanger processing device 100 also includes a pushing part 24, at least part of which is located in the second accommodating part 21, and the pushing part 24 can move along the second direction. The first accommodating part 11 is located on one side of the second accommodating part 21 along the second direction, so that the pushing part 24 can push the heat exchange tube 4 located in the second accommodating part 21 to move along the second direction, and push the heat exchange tube 4 into the first hole 31 of the multiple fins 3 located in the first accommodating part 11.

[0050] The first limiting member 121 includes a plurality of first comb-tooth portions 1211, and a first groove 1212 is provided between two adjacent first comb-tooth portions 1211. The second accommodating portion 21 and the first groove 1212 are correspondingly arranged in the second direction, that is, one second accommodating portion 21 and one first groove 1212 are correspondingly arranged in the second direction, and the second accommodating portion 21 is close to the first limiting member 121 relative to the second limiting member 122, so that when the heat exchange tube 4 passes through the plurality of fins 3, it first passes through the first groove 1212 of the first limiting member 121, and the heat exchange tube 4 located in the second accommodating portion 21 passes through the first groove 1212, the first groove 1212 is arranged corresponding to the first hole 31 of the fin 3, and then passes through the first holes 31 of the plurality of fins 3, so that the heat exchange tube 3 can be aligned with the position of the first holes 31 of the plurality of fins 3, thereby improving the position accuracy of the heat exchange tube 4 when passing through the first hole 31 of the fin 3.

[0051] The heat exchanger processing device 100 can be used to process a heat exchanger 200 as shown in FIG16 . As shown in FIG16 , the heat exchanger 200 includes a fin 3, which includes a plurality of first holes 31, which are spaced apart along the length direction of the fin 3. There are multiple fins 3, and the plurality of fins 3 are spaced apart along the thickness direction of the fin 3. The heat exchanger 200 also includes a heat exchange tube 4, which passes through the first holes 31 on the fin 3 and is connected to the fin 3. Since a heat exchange tube 4 of the heat exchanger needs to pass through multiple stacked fins 3, a slight deviation in the position of the heat exchange tube 4 or the position of the fin 3 during the process of the heat exchange tube 4 passing through the fin 3 may cause the heat exchange tube 4 to become stuck or tilted when passing through the fin 3, thereby affecting the yield rate of the heat exchange tube 4 passing through the fin 3 and the processing efficiency of the heat exchanger.

[0052] As shown in Figures 2 and 5, when the heat exchanger processing device 100 is in use, the fins 3 are placed in the first receiving portion 11 of the first component 1. When the fins 3 are placed on the first receiving portion 11, multiple fins 3 are arranged in the first receiving portion 11 along the second direction. The heat exchange tubes 4 are placed in the second receiving portion 21 of the second component 2, with one heat exchange tube 4 placed in each second receiving portion 21. When the heat exchange tubes 4 are placed in the second receiving portion 21, the length direction of the heat exchange tubes 4 extends along the second direction. The multiple heat exchange tubes 4 are arranged at intervals along the first direction. At least part of the pushing portion 24 is located in the second receiving portion 21. When the pushing portion 24 moves in the second direction, it drives the heat exchange tubes 4 in the second receiving portion 21 to move in the second direction, pushing the heat exchange tubes 4 into the first holes 31 of the multiple fins 3, completing the assembly of the heat exchange tubes 4 and the fins 3. For better understanding, as shown in Figure 2, the fins 3 and heat exchange tubes 4 are placed on the heat exchanger processing device 100.

[0053] The first accommodating portion 11 of the heat exchanger processing device 100 is used to place the fin 3, and the limiting portion 12 includes a first limiting member 121 and a second limiting member 122 arranged opposite to each other in the second direction, and the limiting portion 12 limits the fin 2 in the second direction, thereby reducing the problems of the heat exchange tube 4 being blocked and pushed due to position changes during the process of the heat exchange tube 4 passing through the fin 3. The second accommodating portion 21 is used to place the heat exchange tube 4. When the heat exchanger processing device is in working state, the pushing portion 24 drives the heat exchange tube 4 located in the second accommodating portion 21 to move along the second direction, and the first accommodating portion 11 is located on one side of the second accommodating portion 21 along the second direction. , push the heat exchange tube 4 into the first holes 31 of the multiple fins 3, and the second accommodating portion 21 is close to the first limiting member 121. When the heat exchange tube 4 in the second accommodating portion 21 moves along the second direction, it first passes through the first groove 1212 of the first limiting member 121. The second accommodating portion 21 and the first groove 1212 are correspondingly arranged in the second direction, so that the multiple heat exchange tubes 4 can be aligned with the positions of the first holes of the fins to be penetrated, thereby improving the position accuracy of the heat exchange tube 4 when penetrating the first holes 31 of the fin 3, reducing the problems of jamming and pushing of the heat exchange tube 4 during the penetration process, thereby improving the yield rate of the heat exchange tube penetrating the fin, and improving the processing efficiency of the heat exchanger.

[0054] In some embodiments, the pushing portion 24 includes a first plate 25 and a first piece 26 , the first piece 26 can be movably connected to the first plate 25 , there are multiple first pieces 26 , and the multiple first pieces 26 are arranged at intervals along the first direction, and at least part of the first pieces 26 are located in the second accommodating portion 21 .

[0055] As shown in Figures 4 to 7, the pushing portion 24 includes a first plate 25 and a first piece 26. The length direction of the first plate 25 is parallel to the first direction. The first piece 26 can be movably connected to the first plate 25. Optionally, the first piece 26 and the first plate 25 can be connected by screws, by magnetic attraction, or by other movably connected methods, which are not limited here.

[0056] There are multiple first pieces 26, and the multiple first pieces 26 are arranged at intervals along the first direction. There are multiple first pieces 26, and optionally, the number of first pieces 26 can be consistent with the number of heat exchange tubes 4. One first piece 26 is located in one second accommodating portion 21, driving the displacement of one heat exchange tube 4. Multiple first pieces 26 are connected to the first plate 25. When the push portion 24 moves in the second direction, the multiple first pieces 26 also move simultaneously, driving the multiple heat exchange tubes 4 located in the second accommodating portion 21 to move simultaneously in the second direction. The first piece 26 and the first plate 25 are movably connected, making the heat exchanger processing device 100 more flexible. The same number of first pieces 26 can be matched according to the number of heat exchange tubes 4, thereby adapting to a variety of different heat exchangers and improving the applicability of the heat exchanger processing device.

[0057] When the heat exchanger processing device 100 is in use, the heat exchange tube 4 is placed in the second accommodating portion 21, and at least part of the first piece 26 is located in the second accommodating portion 21, so that it can contact the heat exchange tube 4. When the pushing portion 24 is driven to move in the second direction, the first piece 26 of the pushing portion 24 drives the heat exchange tube 4 to move in the second direction, pushing the heat exchange tube 4 into the first holes 31 of the multiple fins 3, thereby completing the assembly of the heat exchange tube 4 and the fins 3.

[0058] Optionally, the pushing portion 24 may be driven to move by a driving member, may be driven to move manually, or may be moved in other ways, which are not limited here.

[0059] In some embodiments, the first member 26 includes a protrusion 261 , at least a portion of the protrusion 261 protruding from the first plate 25 in the second direction.

[0060] Specifically, as shown in Figures 6 and 7, the first piece 26 includes a protrusion 261. The cross-sectional profile of the protrusion 261 can be similar to the cross-sectional profile of the heat exchange tube 4, and can better contact the heat exchange tube 4, thereby driving the heat exchange tube 4 to penetrate into the fin 3, and ensuring that the position of the heat exchange tube 4 will not shift during the process of penetrating the fin, thereby reducing the problems of jamming and tilting of the heat exchange tube 4 during the penetration process. Since the first plate 25 of the pushing portion 24 has a certain width in the second direction, when the first driving member 23 drives the pushing portion 24 to move in the second direction, when the pushing portion 24 moves to the second accommodating portion 21 close to the end of the first accommodating portion 11, the end of the heat exchange tube 4 cannot be pushed in further along the second direction. The protrusion 261 of the first member 26 is provided to protrude from the first plate 25 in the second direction, so that the end of the heat exchange tube 4 can be pushed in further along the second direction during the process of the heat exchange tube 4 penetrating into the fin 3, thereby completing the penetration of the heat exchange tube 4 into a plurality of fins 3 stacked along the second direction, thereby improving the processing efficiency of the heat exchanger processing device.

[0061] In some embodiments, the second component 2 further includes a first driving member 23 and a first screw rod 28 . The first screw rod 28 is connected to the first driving member 23 . The first screw rod 28 is connected to the pushing portion 24 . The first screw rod 28 is extended along the second direction.

[0062] Specifically, as shown in Figures 4-5, the second component 2 also includes a first driving member 23 and a first screw rod 28. The first screw rod 28 can be arranged on the base 10, and the first screw rod 28 is connected to the first driving member 23. The first screw rod 28 is connected to the pushing portion 24. Optionally, the first screw rod 28 is connected to the first plate 25 of the pushing portion 24. The first screw rod 28 is extended along the second direction. When the heat exchanger processing device 100 is in use, the first driving member 23 is started, and the first driving member 23 drives the pushing portion 24 to move along the extension direction of the first screw rod 28, that is, along the second direction, thereby driving the heat exchange tube 4 to move along the second direction and penetrate into the first hole of the fin 3, thereby improving the processing efficiency of the heat exchanger.

[0063] It is understandable that the first driving member 23 may be a motor, a cylinder, or other structures capable of achieving driving, which is not limited here.

[0064] In some embodiments, the second assembly 2 further includes a first drive member 23 and a first guide rail 29. As shown in Figures 4 and 5, the first guide rail 29 is disposed on the base 10 and is connected to the pusher 24. The first guide rail 29 is connected to the first drive member 23, and the first guide rail 29 extends along the second direction. When the heat exchanger processing device 100 is in use, the first drive member 23 is activated, and the first drive member 23 drives the pusher 24 to move along the extension direction of the first guide rail 29, i.e., along the second direction. This drives the heat exchange tube 4 to move along the second direction and penetrate into the first hole of the fin 3, thereby improving the processing efficiency of the heat exchanger.

[0065] In some embodiments, as shown in Figures 4 and 5, the second assembly 2 further includes a first driving member 23, a first screw rod 28, and a first guide rail 29. The first screw rod 28 is disposed on the base 10 and extends along the second direction. The first guide rail 29 is disposed on the base 10 and extends along the second direction. The pushing portion 24 is connected to both the first screw rod 28 and the first guide rail 29. When the heat exchanger processing device 100 is in use, the first driving member 23 is activated. The first driving member 23 drives the pushing portion 24 to move along the extension direction of the first screw rod 28 and the extension direction of the first guide rail 29 at the same time. This reduces the positional deviation of the heat exchange tube 4 when it is pushed in due to a slight deviation in the direction when the pushing portion 24 moves only along the extension direction of the first screw rod 28 or the first guide rail 29. This improves the accuracy of the movement of the heat exchange tube 4 along the second direction, further improves the yield rate of the heat exchange tube 4 inserted into the fin 3, and improves the processing efficiency of the heat exchanger.

[0066] In some embodiments, as shown in Figure 8, the heat exchanger processing device 100 also includes a first part 22, which is extended along the second direction. The extension direction of the first part 22 is consistent with the extension direction of the second accommodating part 21, and multiple second accommodating parts 21 are located in the first part 22. Therefore, multiple second accommodating parts 21 can be formed by integral processing of the first part 22, thereby improving the reliability of the second accommodating parts 21. Moreover, when multiple heat exchange tubes 4 are placed in the second accommodating parts 21, the positions of the multiple heat exchange tubes 4 are more accurate, thereby improving the accuracy of the position of the heat exchange tubes 4 during the process of penetrating the fins 3, and improving the reliability of the heat exchange tubes 4 when penetrating the multiple fins 3, thereby improving the reliability of the heat exchanger processing device 100.

[0067] It is understandable that the plurality of second accommodating portions 21 may also be formed by other means, such as by forming a plurality of second accommodating portions 21 by spacing a plurality of vertical plate-like structures, which is not limited here.

[0068] In some embodiments, the width of the second accommodating portion 21 is smaller than the height of the second accommodating portion 21, the width direction of the second accommodating portion 21 is parallel to the first direction, and the height direction of the second accommodating portion 21 is parallel to the third direction. Figure 8 is a cross-sectional schematic diagram of the second accommodating portion 21 in a plane perpendicular to the second direction (y direction), and the width of the second accommodating portion 21 is smaller than the height of the second accommodating portion 21.

[0069] When the heat exchange tube 4 of the heat exchanger 200 is a flat heat exchange tube 4, that is, when the heat exchange tube 4 is a flat tube, the heat exchange tube 4 has a width and a thickness, and the thickness of the heat exchange tube is smaller than the width of the heat exchange tube. When the flat heat exchange tube 4 is placed in the second accommodating portion 21 of the heat exchanger processing device 100, the heat exchange tube 4 is vertically placed in the second accommodating portion 21, and the length direction of the heat exchange tube 4 is parallel to the second direction. At this time, the thickness direction of the heat exchange tube 4 is parallel to the first direction (x direction), that is, parallel to the width direction of the second accommodating portion 21, and the width direction of the heat exchange tube 4 is parallel to the third direction (z direction), that is, parallel to the height direction of the second accommodating portion 21. The width of the second accommodating portion 21 is smaller than the height of the second accommodating portion 21, which is convenient for placing the flat heat exchange tube 4 into the second accommodating portion 21 and for inserting the heat exchange tube 4 into the first hole 31 of the fin 3. It can be understood that when the heat exchange tube 4 is a flat heat exchange tube 4, the cross-sectional profile of the heat exchange tube 4 is generally elliptical, and accordingly, the first hole 31 of the fin 3 is also generally elliptical, which facilitates the heat exchange tube 4 to penetrate the first hole 31 of the fin 3 and realize the connection between the heat exchange tube 4 and the fin 3.

[0070] In some embodiments, as shown in FIG8 , the second accommodating portion 21 includes an opening 211 , and the opening 211 is provided with an outward chamfer. The heat exchange tube 4 is placed into the second accommodating portion 21 from the opening 211 of the second accommodating portion 21 . The opening 211 of the second accommodating portion 21 is provided with an outward chamfer, which makes it easier to place the heat exchange tube 4 and reduces damage to the heat exchange tube 4 during placement and movement of the heat exchange tube 4 , thereby improving the reliability of the heat exchanger processing device 100 .

[0071] In some specific embodiments, the cross-sectional size of the second accommodating portion 21 can be slightly larger than the cross-sectional size of the heat exchange tube 4. The cross-sectional size of the second accommodating portion 21 refers to the cross-sectional size of the second accommodating portion 21 in the plane perpendicular to the second direction. The cross-sectional size of the heat exchange tube 4 refers to the cross-sectional size of the heat exchange tube 4 in the direction perpendicular to the length of the heat exchange tube, that is, the cross-sectional size perpendicular to the plane of the second direction. The cross-sectional size of the second accommodating portion 21 can be slightly larger than the cross-sectional size of the heat exchange tube 4, which is more convenient for placing the heat exchange tube 4 and reduces damage to the heat exchange tube when placing the heat exchange tube 4, thereby improving the reliability of the heat exchanger processing device.

[0072] Optionally, the cross-sectional size of the second accommodating portion 21 can be 107%-115% of the cross-sectional size of the heat exchange tube 4. When the cross-sectional size of the second accommodating portion 21 is smaller than 107% of the cross-sectional size of the heat exchange tube 4, in the process of the heat exchange tube 4 moving along the second direction to penetrate the fin 3, the friction between the heat exchange tube 4 and the second accommodating portion 21 is too large, which may damage the heat exchange tube 4. When the cross-sectional size of the second accommodating portion 21 is larger than 115% of the cross-sectional size of the heat exchange tube 4, the gap between the heat exchange tube 4 and the second accommodating portion 21 when the heat exchange tube 4 is placed in the second accommodating portion 21 is too large, and the heat exchange tube 4 may tilt or shift in the second accommodating portion 21. In particular, when the heat exchange tube 4 is a flat heat exchange tube 4, the tilt or shift of the position of the heat exchange tube 4 will cause the position of the heat exchange tube 4 to shift when it penetrates the fin 3, affecting the yield of the heat exchange tube 4 penetrating the fin 3. Therefore, the cross-sectional size of the second accommodating portion 21 is set within the range of 107%-115% of the cross-sectional size of the heat exchange tube 4, which can reduce the positional deviation of the heat exchange tube 4 when it is placed in the second accommodating portion 21, and reduce the friction during the movement of the heat exchange tube 4, thereby improving the yield rate of the heat exchange tube 4 penetrating the fin 3, improving the processing efficiency of the heat exchanger, and improving the reliability of the heat exchanger processing device.

[0073] In some embodiments, as shown in Figures 5 and 9, the second component 2 also includes a second plate 27, which is located at one end of the second accommodating portion 21 close to the first accommodating portion 11 in the second direction. The second plate 27 extends along the first direction, and the second plate 27 includes a second hole 271. The second hole 271 penetrates the second plate 27 along the second direction. There are multiple second holes 271, and the multiple second holes 271 are arranged at intervals along the first direction.

[0074] Specifically, as shown in Figures 9-11, the second plate 27 includes a first side surface 27a and a second side surface 27b arranged opposite to each other along the second direction. The second side surface 27b is closer to the first accommodating portion 11 relative to the first side surface 27a, and the flow cross-section of the second hole 271 on the second side surface 27b is smaller than the flow cross-section of the second hole 271 on the first side surface 27a.

[0075] When the heat exchanger processing device 100 is in use, the heat exchange tube 4 located in the second accommodating portion 21 starts to move along the second direction to prepare to penetrate the fin 3. Since the second plate 27 is located at the end of the second accommodating portion 21 close to the first accommodating portion 11 in the second direction, the heat exchange tube 4 must first pass through the second plate 27 and then move along the second direction to penetrate the fin 3. When the heat exchange tube 4 passes through the second plate 27, the heat exchange tube 4 first passes through the second hole 271 on the second plate 27. One heat exchange tube 4 passes through one second hole 271, and multiple heat exchange tubes 4 pass through multiple second holes 271 on the second plate 27 at the same time.

[0076] When the heat exchange tube 4 passes through the second hole 271 on the second plate 27 and starts to move in the second direction, the second side surface 27b of the second plate 27 is closer to the first accommodating portion 11 than the first side surface 27a. The heat exchange tube 4 first passes through the first side surface 27a of the second plate 27 and then through the second side surface 27b of the second plate 27. Since the flow cross section of the second hole 271 on the second side surface 27b is smaller than the flow cross section of the second hole 271 on the first side surface 27a, the heat exchange tube 4 first passes through the second hole 271 with a slightly larger flow cross section. When the heat exchange tube 4 is about to pass through the second hole 271 and come out, the heat exchange tube 4 The tube 4 then passes through the second hole 271 with a slightly smaller flow cross-section. Through the design of the second hole 271, the position of the heat exchange tube 4 passing through the second hole 271 is guided. Especially when the heat exchange tube 4 is a flat heat exchange tube, the position of the flat heat exchange tube 4 passing through the second hole 271 can be guided, so that the position of the heat exchange tube 4 to be passed through the fin 3 is more accurately aligned with the first hole 31 of the fin 3, which is more conducive to the heat exchange tube 4 passing through the fin 3, reducing the problems of jamming, pushing and tilting when the heat exchange tube 4 passes through the fin 3, thereby improving the yield of the heat exchange tube 4 passing through the fin 3.

[0077] Optionally, the second hole 271 includes at least a portion of an oblique line segment or at least a portion of an arcuate segment in a cross section perpendicular to the first direction, wherein the oblique line segment or the arcuate segment is closer to the first side 27a than the second side 27b. Specifically, as shown in FIG10 , in a cross section perpendicular to the first direction, the second hole 271 includes a portion of an arcuate segment, wherein the arcuate segment is closer to the first side 27a than the second side 27b. As shown in FIG11 , in a cross section perpendicular to the first direction, the second hole 271 includes a portion of an oblique line segment, wherein the oblique line segment is closer to the first side 27a than the second side 27b. As a result, the flow cross section of the second hole 271 in the second side 27b is smaller than the flow cross section of the second hole 271 in the first side 27a, thereby correcting the position of the heat exchange tube 4, so that the position of the heat exchange tube 4 to be inserted into the fin 3 is more accurately aligned with the first hole 31 of the fin 3, further facilitating the heat exchange tube 4 to penetrate the fin 3 and improving the yield rate of the heat exchange tube 4 penetrating the fin 3.

[0078] It can be understood that in order to make the flow cross-section of the second hole 271 on the second side 27b smaller than the flow cross-section of the second hole 271 on the first side 27a, in the cross-section perpendicular to the first direction, the second hole 271 is not limited to including an oblique segment or an arc segment, and can also be other structures, which is not limited here.

[0079] In some embodiments, the second hole 271 includes a straight line segment in a cross section perpendicular to the first direction, the straight line segment extends along the second direction, and the straight line segment is closer to the second side surface 27 b relative to the first side surface 27 a.

[0080] Specifically, as shown in Figures 10 and 11, on the cross-section perpendicular to the first direction, the second hole 271 includes a partial straight segment, and the straight segment is closer to the second side surface 27b than the first side surface 27a. The heat exchange tube 4 guided through the second hole 271 is provided with a straight segment on the side close to the second side surface 27b. This is to allow the heat exchange tube 4 after guidance to better maintain position stability, so that the heat exchange tube 4 after guidance can be more accurately aligned with the first hole 31 of the fin 3, thereby reducing problems such as heat exchange tube jamming and pushing due to position offset when the heat exchange tube 4 penetrates the fin 3, further improving the yield rate of the heat exchange tube penetrating the fin, and improving the processing efficiency of the heat exchanger.

[0081] In some embodiments, the second limiting member 122 includes a second comb-tooth portion (not shown in the figure), and the second comb-tooth portion and the first comb-tooth portion 1211 are correspondingly arranged along the second direction.

[0082] Specifically, as shown in Figures 13 and 14, the first limiting member 121 includes a first comb tooth portion 1211, and the second limiting member 122 includes a second comb tooth portion. The structure of the second limiting member 122 is substantially the same as that of the first limiting member 121. The first groove 1212 between adjacent comb tooth portions of the first comb tooth portion is used for the insertion of the heat exchange tube 4. There is a second groove between adjacent comb tooth portions of the second comb tooth portion, and the second groove is used for the insertion of the heat exchange tube 4. The first limiting member 121 is closer to the second accommodating portion 21 than the second limiting member 122, and the first comb-tooth portion 1211 is closer to the second plate 27 than the second comb-tooth portion. The setting of the first groove 1212 of the first limiting member 121 can make the heat exchange tube 4 align with the position of the first hole 31 of the fin 3 to be inserted, and can also support the heat exchange tube 4 passing through the fin 3. The second groove of the second limiting member 122 can support the heat exchange tube 4 after passing through the fin 3, which is beneficial to make the position of the heat exchange tube 4 more accurate when the heat exchange tube 4 passes through the fin 3, thereby improving the finished product rate of the heat exchange tube 4 passing through the fin 3. The first comb-tooth portion 1211 and the second comb-tooth portion are correspondingly arranged along the second direction, and the first groove 1212 between the two adjacent first comb-tooth portions 1211 and the second groove between the two adjacent second comb-tooth portions are used to place the same heat exchange tube 4, which supports the heat exchange tube 4 in the process of penetrating the fin 3, is beneficial for making the position of the heat exchange tube 4 more accurate when the heat exchange tube 4 penetrates the fin 3, and improves the finished product rate of the heat exchange tube 4 penetrating the fin 3.

[0083] In some embodiments, as shown in Figures 3 and 12, the second stopper 122 is movable along the second direction, allowing the heat exchanger processing device 100 to adapt to fin structures of different sizes, thereby improving the applicability of the heat exchanger processing device. When the structure of the heat exchanger 200 is different, the structure of the fins 3 is different, and the position of the fins 3 on the first accommodating portion 11 is different. Therefore, multiple fins 3 can be placed on the first accommodating portion 11 near the first stopper 121. The position of the second stopper 122 is then adjusted according to the placement of different fins, so that the first stopper 121 and the second stopper 122 can limit the fins placed in the first accommodating portion 11 in the second direction.

[0084] It is understood that the first stopper 121 can also be configured to be movable along the second direction to improve the applicability of the heat exchanger processing device, and this is not limited here. Optionally, the first stopper 121 and the second stopper 122 can be plate-shaped structures or other structures that can serve as a limiter. The structures of the first stopper 121 and the second stopper 122 are not limited here.

[0085] In some embodiments, the first limit member 121 is movable along a third direction, and / or the second limit member 122 is movable along a third direction, the third direction being the z direction in FIG1 . After the heat exchange tube 4 passes through a plurality of fins 3, the heat exchange tube 4 will extend a certain distance beyond the fins in the second direction, and the heat exchange tube 4 needs to be installed with headers at both ends of the length direction of the heat exchange tube. At this time, the first limit member 121 can be moved along the third direction, and / or the second limit member 122 can be moved along the third direction to reduce interference with the first limit member 121 and / or the second limit member 122, making it more convenient to subsequently install the header, thereby making the heat exchanger processing device 100 more convenient to operate.

[0086] Specifically, the first stopper 121 moves downward along the third direction, as shown in Figure 13 . At this point, the first comb-tooth portion 1211 also moves downward along the third direction. At this point, the heat exchange tube 4 no longer contacts the first stopper 121. Consequently, the first stopper 121 does not interfere with the heat exchanger manufacturing process, allowing the header to be installed at the end of the heat exchange tube 4. Similarly, the second stopper 122 can move downward along the third direction. At this point, the other end of the heat exchange tube 4 in the longitudinal direction no longer contacts the second stopper 122. Consequently, the second stopper 122 does not interfere with the heat exchanger manufacturing process, allowing the header to be installed at the other end of the heat exchange tube 4.

[0087] In some embodiments, as shown in Figures 3 and 12, the limiting portion 12 also includes a third limiting member 123 and a fourth limiting member 124. The third limiting member 123 and the fourth limiting member 124 are arranged relative to each other along the first direction. At least part of the third limiting member 123 protrudes from the first accommodating portion 11 in the third direction, and at least part of the fourth limiting member 124 protrudes from the first accommodating portion 11 in the third direction. The third limiting member 123 is extended along the second direction, and the fourth limiting member 124 is extended along the second direction. The third limiting member 123 and the fourth limiting member 124 can be limited in the first direction.

[0088] When the heat exchanger processing device 100 is in use, the fin 3 is located on the first accommodating portion 11, the third limiting member 123 and the fourth limiting member 124 can limit the fin 3 in the first direction, the first limiting member 121 and the second limiting member 122 can limit the fin 3 in the second direction, and the limiting portion 12 limits the fin 3 in both the first direction and the second direction, further reducing the problems of jamming and tilting of the heat exchange tube 4 during the process of the heat exchange tube 4 penetrating into the fin 3 along the second direction due to the force during the penetration process causing the position of the fin 3 to change, thereby improving the yield rate of the heat exchange tube 4 penetrating into the fin 3.

[0089] Optionally, the third limiting member 123 and the fourth limiting member 124 may be plate-shaped structures, or other structures capable of limiting the position. The structures of the third limiting member 123 and the fourth limiting member 124 are not limited herein.

[0090] In some embodiments, as shown in Figures 3 and 12 , the fourth stopper 124 is movable along the first direction, enabling the heat exchanger processing apparatus 100 to accommodate fins 3 of varying sizes, thereby improving the applicability of the heat exchanger processing apparatus. It is understood that the third stopper 123 may also be movable along the first direction to improve the applicability of the heat exchanger processing apparatus, without limitation herein.

[0091] Optionally, when the arranged multiple fins 3 are placed in the first accommodating portion 11, the fins 3 are initially positioned by the first limiting member 121 and the third limiting member 123 of the limiting portion 12, and the position of the second limiting member 122 in the second direction is adjusted according to the thickness of the multiple fins 3 in the second direction, so that the first limiting member 121 and the second limiting member 122 can limit the fins 3 in the second direction, and the position of the fourth limiting member 124 in the first direction is adjusted according to the length of the fins 3 in the first direction, so that the third limiting member 123 and the fourth limiting member 124 can limit the fins 3 in the first direction, thereby limiting the multiple fins 3 in the first and second directions, improving the applicability of the heat exchanger processing device, reducing the problems of jamming and pushing of the heat exchange tube 4 during the insertion of the fin 3 due to the change in the position of the fin 3, and improving the yield rate of the heat exchange tube 4 passing through the fin 3.

[0092] In some embodiments, the heat exchanger processing device 100 further includes a first guide rod 15 , and the cross-sectional size of the first guide rod 15 is 100%-101% of the cross-sectional size of the heat exchange tube 4 .

[0093] Specifically, after the fins 3 are placed in the first accommodating portion 11, the first guide rod 15 can be inserted into the first holes 31 of the multiple fins 3. The structure of the first guide rod 15 is shown in Figure 15. Optionally, a first guide rod 15 can be inserted at both ends of the fin 3 in the length direction. The first holes 31 of the fin 3 are used for inserting the heat exchange tube 4. The cross-sectional size of the first guide rod 15 is 100%-101% of the cross-sectional size of the heat exchange tube 4. Using the first guide rod 15 with a larger cross-sectional size to insert into the first hole 31 can make the first holes 31 of the multiple fins 3 more neatly arranged. When the heat exchange tube 4 inserts into the fin 3, it needs to pass through multiple stacked fins 3. The first holes 31 on the multiple fins 3 are more neatly arranged. When the heat exchange tube 4 inserts into the first hole 31, it is less likely to cause the heat exchange tube to be stuck or pushed askew, which is more conducive to the heat exchange tube 4 inserting into the fin 3. Therefore, the yield rate of the heat exchange tube 4 inserting into the fin 3 is improved, and the processing efficiency of the heat exchanger is improved.

[0094] After the first guide rod 15 is inserted into the plurality of fins 3 and shaped, the plurality of fins 3 are positioned in the first and second directions. After the fins are positioned, the first guide rod 15 can be removed to facilitate the subsequent insertion of the heat exchange tube 4 into the fin 3. It is understood that the cross-sectional dimensions of the heat exchange tube 4 refer to the cross-section of the heat exchange tube 4 perpendicular to the length of the heat exchange tube. The overall cross-sectional profile of the first guide rod 15 is substantially the same as the cross-sectional profile of the heat exchange tube 4. Optionally, as shown in FIG15 , to facilitate the insertion of the first guide rod 15 into the plurality of fins 3, one end of the first guide rod 15 can be a sharpened structure to facilitate insertion into the first holes 31 of the plurality of fins 3 during processing. The overall cross-sectional profile of the first guide rod 15 is still substantially the same as the cross-sectional profile of the heat exchange tube 4.

[0095] In some embodiments, as shown in FIG12 , the first assembly 1 further includes a second guide rail 13 and a second drive member 14. The second guide rail 13 is disposed on the first accommodating portion 11 and extends along a first direction. The second drive member 14 is connected to the second guide rail 13 and can drive the first accommodating portion 11 to move along the extension direction of the second guide rail 13, that is, along the first direction. When the heat exchanger processing device 100 is in use, the fin 3 is located on the first accommodating portion 11, and the first accommodating portion 11 is movable along the first direction. This allows the heat exchanger to be processed in the appropriate position, making the heat exchanger processing device 100 more convenient to operate. The second drive member 14 drives the first accommodating portion 11 to move, thereby improving the processing efficiency of the heat exchanger processing device.

[0096] It is understandable that the second driving member 14 can be a motor, a cylinder, or other structures capable of achieving driving, which is not limited here.

[0097] The present invention also provides a heat exchanger processing method, comprising the following steps:

[0098] The fin 3 is placed in the first receiving portion 11. The fin 3 includes a plurality of first holes 31. There are multiple fins 3, and the multiple fins 3 are spaced apart along the thickness direction of the fin.

[0099] Limiting the fin 3 in the thickness direction of the fin;

[0100] Place the heat exchange tube 4 into the second receiving portion 21 , with the length direction of the second receiving portion 21 parallel to the thickness direction of the fins;

[0101] The heat exchange tube 4 is driven to move along the thickness direction of the fin. The heat exchange tube 4 first passes through the first groove 1212 and then passes through the first holes 31 of multiple fins 3. The first groove 1212 and the second accommodating portion 21 are correspondingly arranged in the thickness direction of the fin. The first groove 1212 and the first hole 31 are correspondingly arranged in the thickness direction of the fin.

[0102] Optionally, a heat exchanger 200 can be processed using the heat exchanger processing apparatus 100. The heat exchanger 200 can be as shown in FIG16 . The heat exchanger 200 includes a fin 3 and a heat exchange tube 4. The fin 3 includes a plurality of first holes 31, which are spaced apart along the length direction of the fin 3. There are multiple fins 3, and the plurality of fins 3 are spaced apart along the thickness direction of the fin 3. The length direction of the fin 3 is consistent with the first direction in the figure, that is, the x-direction, and the thickness direction of the fin 3 is consistent with the second direction in the figure, that is, the y-direction.

[0103] When assembling the heat exchanger 200, the fin 3 is placed on the first accommodating portion 11 of the heat exchanger processing device 100. When the fin 3 is placed on the first accommodating portion 11, the length direction of the fin 3 extends along the first direction, and the multiple first holes on the fin 3 are arranged at intervals along the first direction. There are multiple fins 3, and the multiple fins 3 are arranged at intervals along the second direction.

[0104] The fins 3 are limited in the second direction by the limiting portion 12. Optionally, when the arranged multiple fins 3 are placed in the first accommodating portion 11, the fins 3 can be initially positioned by the first limiting member 121 of the limiting portion 12. According to the thickness of the multiple fins 3 in the second direction, the position of the second limiting member 122 in the second direction is adjusted so that the first limiting member 121 and the second limiting member 122 can limit the fins 3 in the second direction. The limiting portion 12 limits the fins 3 in the second direction, which can better ensure the position of the fins 3 when the heat exchange tube 4 passes through the fin 3, reduce the problems of the heat exchange tube 4 being stuck or tilted due to position changes during the process of passing the heat exchange tube 4 through the fin 3, improve the yield rate of the heat exchange tube 4 passing through the fin 3, and improve the processing efficiency of the heat exchanger.

[0105] Place the heat exchange tube 4 in the second receiving section 21, with the length of the second receiving section 21 parallel to the second direction. The second receiving section 21 extends in the second direction, with one heat exchange tube 4 placed in each second receiving section 21. Place multiple heat exchange tubes 4 in multiple second receiving sections 21, with the length of the second receiving sections 21 parallel to the second direction. The heat exchange tubes 4 in the second receiving sections 21 extend in the second direction. Place the heat exchange tubes 4 in the second receiving sections 21 and move them along the length of the second receiving sections 21, i.e., in the second direction, until they pass through the first holes 31 of the fins 3.

[0106] When the heat exchange tube 4 is driven to move along the second direction, the heat exchange tube 4 first passes through the first groove 1212 and then passes through the first holes 31 of the multiple fins 3. The first groove 1212 and the second accommodating portion 21 are correspondingly arranged in the thickness direction of the fin. Moreover, the first groove 1212 and the first hole 31 are correspondingly arranged in the thickness direction of the fin, so that the heat exchange tube 4 can be aligned with the position of the first hole 31 of the fin 3 to be penetrated through the first groove 1212, thereby improving the position accuracy of the heat exchange tube 4 when penetrating the fin 3, reducing the problems of jamming, pushing and tilting of the heat exchange tube 4 during the penetration process, thereby improving the yield rate of the heat exchange tube 4 penetrating the fin 3 and improving the processing efficiency of the heat exchanger.

[0107] The heat exchange tube 4 is driven to move in the second direction so as to pass through the first holes 31 of the multiple fins 3. The heat exchange tube 4 is driven to move in the second direction along the length of the heat exchange tube 4. When the multiple heat exchange tubes 4 are simultaneously moved in the second direction, they pass through the first holes 31 on the multiple fins 3 in sequence. After the same heat exchange tube 4 passes through the first holes 31 on the multiple fins 3 in the second direction, the assembly of the heat exchange tube 4 and the fins 3 is completed. FIG2 is a schematic diagram of the multiple heat exchange tubes 4 after they have passed through the fins 3.

[0108] The heat exchanger processing method places the fin 3 in the first accommodating portion 11, limits the fin 3 in the second direction, and places the heat exchange tube 4 in the second accommodating portion 21. The length direction of the second accommodating portion 21 is parallel to the second direction, and drives the heat exchange tube 2 located in the second accommodating portion 21 to move along the second direction, so that the heat exchange tube 2 passes through the first holes 31 of the multiple fins 3. When the heat exchange tube 2 moves along the second direction, it first passes through the first groove 1212 and then passes through the first holes 31 of the multiple fins 3. The first groove 1212 and the second accommodating portion 21 are correspondingly arranged in the second direction, and the first groove 1212 and the first hole 31 are correspondingly arranged in the second direction, so that the heat exchange tube 4 can be aligned with the position of the first hole 31 of the fin 3 to be penetrated, thereby improving the position accuracy of the heat exchange tube 4 when penetrating the fin 3, reducing the problems of heat exchanger jamming and pushing when the heat exchange tube 4 penetrates the fin 3, improving the yield rate of the heat exchange tube 4 penetrating the fin 3, and improving the processing efficiency of the heat exchanger.

[0109] Optionally, the first driving member 23 may be used to drive the heat exchange tube 4 to move in the second direction, pushing the heat exchange tube 4 into the first holes 31 of the plurality of fins 3 , thereby further improving the processing efficiency of the heat exchanger 200 .

[0110] In some embodiments, when the heat exchange tube 4 is driven to move along the second direction, the heat exchange tube 4 passes through the second plate 27. The second plate 27 is located at the end of the second accommodating portion 21 in the second direction, and the position of the heat exchange tube 4 is corrected. After correction, the heat exchange tube 4 moves along the second direction, passes through the first groove 1212, and then passes into the first holes 31 of the multiple fins 3.

[0111] Specifically, as shown in FIG2 , when the heat exchange tube 4 is driven to move in the second direction, the heat exchange tube 4 first passes through the second plate 27. The second plate 27 is located at the end of the second accommodating portion 21 close to the first accommodating portion 11 in the second direction. The second plate 27 includes a first side surface 27a and a second side surface 27b arranged opposite to each other in the second direction. The second side surface 27b is closer to the first accommodating portion 11 relative to the first side surface 27a. A plurality of second holes 271 are provided on the second plate 27. The flow cross-section of the second holes 271 on the second side surface 27b is smaller than the flow cross-section of the second holes 271 on the first side surface 27a. When the heat exchange tube 4 passes through the second holes 271, it first passes through the second plate 27. The first side surface 27a with a larger cross-section then passes through the second side surface 27b with a smaller flow cross-section on the second plate 27, so that the position of the inserted heat exchange tube 4 can be corrected. After correction, the positions of the multiple heat exchange tubes 4 are more precise and can be better aligned with the position 31 of the first hole of the fin 3. Then, the multiple heat exchange tubes 4 pass through the first groove 1212, so that the position of the heat exchange tube 4 to be inserted into the fin 3 is more accurately aligned with the first hole 31 of the fin 3, which is more conducive to the heat exchange tube 4 penetrating the fin 3 and reduces the problems of jamming, pushing and tilting when the heat exchange tube 4 penetrates the fin 3, thereby improving the yield of the heat exchange tube 4 penetrating the fin 3 and improving the processing efficiency of the heat exchanger 200.

[0112] It can be understood that when the heat exchange tube 4 is a flat heat exchange tube 4, the position of the flat heat exchange tube 4 is corrected before the heat exchange tube 4 is inserted into the fin 3. The positions of the multiple heat exchange tubes 4 after correction are more precise, and the position of the heat exchange tube 4 can be more accurately aligned with the first hole 31 of the fin 3, which is more conducive to the heat exchange tube 4 passing through the fin 3, and reduces the problems of jamming and pushing when the heat exchange tube 4 passes through the fin 3, thereby improving the yield of the heat exchange tube 4 passing through the fin 3.

[0113] In some embodiments, the heat exchanger processing method further includes the following steps: after placing the fins 3 in the first accommodating portion 11, inserting the first guide rod 15 into the first holes 31 of the plurality of fins 3 so that the plurality of fins 3 are aligned along the second direction, and the cross-sectional size of the first guide rod 15 is 100%-101% of the cross-sectional size of the heat exchange tube 4; limiting the fins in the first direction and the second direction; and removing the first guide rod 15.

[0114] Specifically, after the fins 3 are placed in the first accommodating portion 11, the first guide rod 15 is inserted into the first holes 31 of the multiple fins 3. Optionally, a first guide rod 15 can be inserted into each of the two ends of the fin 3 in the length direction. The cross-sectional size of the first guide rod 15 is 100%-101% of the cross-sectional size of the heat exchange tube 4. The first holes 31 of the fin 3 are used for inserting the heat exchange tube 4. Using a first guide rod 15 that is slightly larger than the cross-sectional size of the heat exchange tube 4 to insert into the first hole 31 can make the multiple fins 3 more neatly arranged along the thickness direction of the fin. When the heat exchange tube 4 inserts into the fin 3, it needs to pass through multiple stacked fins 3. The first holes 31 on the multiple fins 3 are more neatly arranged. When the heat exchange tube 4 inserts into the first hole 31, it is less likely to cause the heat exchange tube to be stuck or pushed sideways, which is more conducive to the heat exchange tube 4 inserting into the fin 3. As a result, the yield rate of the heat exchange tube 4 inserting into the fin 3 is further improved, and the processing efficiency of the heat exchanger is improved.

[0115] It can be understood that the cross-sectional size of the heat exchange tube 4 refers to the size of the heat exchange tube 4 in the cross section perpendicular to the length direction of the heat exchange tube. During the heat exchanger processing, the length direction of the heat exchange tube extends along the second direction, and the cross-sectional profile of the first guide rod 15 is substantially the same as the cross-sectional profile of the heat exchange tube 4.

[0116] After the multiple fins 3 are shaped by the first guide rod 15, the first holes 31 on the multiple fins 3 are arranged more neatly, and then the fins 3 are limited in the first direction and the second direction so that the positions of the fins 3 after being shaped by the first guide rod 15 remain neat. Then, before the heat exchange tube 4 is inserted into the fin 3, the first guide rod 15 is removed to facilitate the subsequent insertion of the heat exchange tube 4 into the first hole 31.

[0117] Optionally, the fins 3 can be initially positioned by the first limiting member 121 and the third limiting member 123 of the limiting portion 12. The position of the second limiting member 122 in the second direction can be adjusted according to the thickness of the plurality of fins 3 in the second direction, so that the first limiting member 121 and the second limiting member 122 can limit the fins 3 in the second direction. The position of the fourth limiting member 124 in the first direction can be adjusted according to the length of the fins 3 in the first direction, so that the third limiting member 123 and the fourth limiting member 124 can limit the fins 3 in the first direction, thereby limiting the plurality of fins 3 in the first and second directions. The limiting portion 12 limits the fins 3 in the first and second directions, which can better ensure the position of the fins 3 when the heat exchange tubes 4 pass through the fins 3, further reducing problems such as heat exchange tube jamming and tilting caused by position changes during the process of the heat exchange tubes 4 passing through the fins 3, improving the yield rate of the heat exchange tubes 4 passing through the fins 3, and improving the processing efficiency of the heat exchanger.

[0118] In some embodiments, after the fins 3 are limited, the following step is further included: driving the first accommodation portion 11 to move along the first direction from the installation area to the working area.

[0119] Specifically, as shown in Figure 3, area A1 in Figure 3 is the working area, and area A2 is the installation area. Area A1 and area A2 are located on the first component 1, and area A1 and area A2 are adjacent to each other in the first direction. The length direction of the first accommodating portion 11 of the heat exchanger processing device 100 extends along the first direction, that is, along the left and right direction in the figure. When assembling the heat exchanger 200, the fins 3 can be placed in the A2 area, and the position of the fins 3 can be limited to avoid inconvenience in operation when placing the fins 3 in the A1 area. The limited fins 3 can be moved to the A1 area along the first direction, that is, along the left and right direction in Figure 3, to facilitate the subsequent heat exchange tubes 4 placed in the second accommodating portion 21 to penetrate into the fins 3 located in the first accommodating portion 11. This arrangement makes operation more convenient, saves time, and improves the processing efficiency of the heat exchanger.

[0120] In some embodiments, after driving the heat exchange tube 4 to pass through the first holes 31 of the plurality of fins 3 , the following steps are also included: driving the first accommodation portion 11 to move from the working area to the installation area, and installing the headers 5 at both ends of the heat exchange tube 4 in the longitudinal direction.

[0121] Specifically, as shown in Figure 3, after driving the heat exchange tube 4 to pass through the first holes 31 of the multiple fins 3, the assembly of the heat exchange tube 4 and the fins 3 is completed. The headers 5 need to be installed at both ends of the heat exchange tube 4 in the length direction. At this time, the first accommodating portion 11 can be moved from area A1 to area A2 along the first direction, that is, along the left and right direction in Figure 3. The assembly of the headers 5 at both ends of the heat exchange tube 4 can be completed in area A2, making the operation more convenient and avoiding interference in the installation of the header 5 in area A1, which affects the installation of the header 5. Therefore, the operation is more convenient, time is saved, and the processing efficiency of the heat exchanger is improved.

[0122] In some embodiments, after the fins 3 are limited, the following steps are also included: driving the first accommodating portion 11 to move from the installation area to the operating area along the first direction; after driving the heat exchange tube 4 to pass through the first hole 31, the following steps are also included: driving the first accommodating portion 11 from the operating area to the installation area, and installing the collecting pipe 5 at both ends of the length direction of the heat exchange tube 4.

[0123] As shown in Figure 3, when assembling the heat exchanger, the fins 3 can be placed in the A2 area first and the fins 3 can be limited. After being limited, the fins 3 can be moved to the A1 area in the left and right directions, so that the heat exchange tubes 4 located in the second accommodating portion 21 can be inserted into the fins 3. After the heat exchange tubes 4 are inserted into the first holes 31 of the fins 3 in the A1 area, the first accommodating portion 11 can be moved from the A1 area to the A2 area in the left and right directions, and the assembly of the headers 5 at both ends of the heat exchange tubes 4 can be completed in the A2 area, which makes the operation more convenient, saves time, and improves the processing efficiency of the heat exchanger.

[0124] Optionally, the first component 1 also includes a second guide rail 13 and a second driving member 14. The second guide rail 13 is connected to the first accommodating portion 11. Driven by the second driving member 14, the first accommodating portion 11 moves along the extension direction of the second guide rail 13, that is, along the first direction, so that the first accommodating portion 11 can be moved from area A1 to area A2, or from area A2 to area A1, further improving the processing efficiency of the heat exchanger.
