Abstract

This application provides a heat exchanger assembly device and assembly method. The heat exchanger assembly device includes a first component and a second component. The first component includes a support member with strip-shaped holes. The length direction of the strip-shaped holes extends along a first direction and penetrates the support member. There are multiple strip-shaped holes, which are spaced apart along a second direction. The second component includes a first pressing part, which is movable relative to the support member. The first direction is the width direction of the first component, and the second direction is the length direction of the first component. In this heat exchanger assembly device, the support member is used to support the fins of the heat exchanger, and the first pressing part is used to support the heat exchange tubes of the heat exchanger. By moving the support member and the first pressing part relative to each other, the heat exchange tubes of the heat exchanger pass through the strip-shaped holes of the support member, and the heat exchange tubes of the heat exchanger are pressed together with the fins of the heat exchanger. This reduces bending or deformation of the fins during assembly and improves the assembly effect between the fins and the heat exchange tubes.

Description

Technical Field

[0001] This application relates to the field of heat exchanger processing technology, specifically to a heat exchanger assembly equipment and assembly method. Background Technology

[0002] A horizontally inserted finned heat exchanger mainly consists of heat exchange tubes and thin, finned plates inserted into the heat exchange tubes. In related technologies, assembly equipment for horizontally inserted finned heat exchangers typically uses clamping assemblies to hold multiple fins together, and then presses the fins onto the heat exchange tubes. During the clamping and pressing process, the clamping assembly needs to have a certain clamping force to prevent the fins from detaching from it. However, because the fins are thin and made of soft material, the clamping assembly can easily cause the fins to bend or deform, affecting the assembly effect between the fins and the heat exchange tubes. Summary of the Invention

[0003] The first aspect of this application provides a heat exchanger assembly device that can reduce bending or deformation of fins during assembly, thereby improving the assembly effect of fins and heat exchange tubes.

[0004] The heat exchanger assembly equipment provided in the first aspect of this application includes: a first component and a second component. The first component includes a support member having a strip-shaped hole. The length direction of the strip-shaped hole extends along a first direction and penetrates the support member. There are multiple strip-shaped holes, and the multiple strip-shaped holes are arranged at intervals along a second direction. The second component includes a first pressing part, and the first pressing part and the support member are movable relative to each other. The first direction is the width direction of the first component, and the second direction is the length direction of the first component.

[0005] When the heat exchanger assembly equipment is in operation, the support member can be used to place the heat exchanger fins, and the first pressing part can be used to place the heat exchanger tubes. The relative movement of the support member and the first pressing part allows the heat exchanger tubes to pass through the slotted holes in the support member, thus pressing the heat exchanger tubes and fins together. This assembly method reduces bending or deformation of the fins during assembly, thereby improving the assembly effect between the fins and heat exchanger tubes.

[0006] A second aspect of this application provides a heat exchanger assembly method, which includes the following steps:

[0007] Multiple fins are arranged on the support component, and multiple heat exchange tubes are arranged on the first pressing part;

[0008] Move the support member and / or the first pressing part so that the heat exchange tube passes through the strip hole on the support member and enters the support member, and the heat exchange tube is at least partially inserted into the slot of the fin.

[0009] The heat exchanger assembly method arranges the heat exchanger fins on the support member and the heat exchanger tubes on the first pressing part. The heat exchanger tubes pass through the strip hole of the support member by the relative movement of the support member and the first pressing part, and the heat exchanger tubes and fins are pressed together. This assembly process reduces the bending or deformation of the fins during the assembly process, thereby improving the assembly effect of the fins and heat exchanger tubes.

[0024] like Figure 1-7 As shown, a first aspect of this application provides a heat exchanger assembly device, which includes a first component and a second component. The first component includes a support member 1, which has a strip-shaped hole 11. The length direction of the strip-shaped hole 11 is along a first direction (e.g., ...). Figure 1 The strip holes 11 extend and penetrate the support member 1 in the front-back direction shown, and there are multiple strip holes 11. The multiple strip holes 11 extend along the second direction (such as...) Figure 1 The components are arranged at intervals in the left-right direction (as shown). The first direction is the width direction of the first component, and the second direction is the length direction of the first component. For example, as shown... Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the first component includes a horizontally arranged support member 1. The support member 1 has multiple strip-shaped holes 11 extending along the width direction of the first component; in other words, the support member 1 has multiple strip-shaped holes 11 extending along the front-back direction. The strip-shaped holes 11 penetrate the support member 1 vertically. The multiple strip-shaped holes 11 are arranged at intervals along the length direction of the first component; in other words, the multiple strip-shaped holes 11 are arranged at intervals along the left-right direction.

[0025] The second component includes a first pressing part 2, and the first pressing part 2 and the support member 1 are movable relative to each other. For example, as Figure 1 , Figure 2 and Figure 5 As shown, the second component includes a horizontally arranged first pressing part 2, and a support member 1 that can be moved to a position that is spaced apart from the first pressing part 2 in the vertical direction, or the support member 1 is located above the first pressing part 2. The support member 1 and the first pressing part 2, or one of them, can move in the vertical direction so that the first pressing part 2 and the support member 1 can move relative to each other.

[0026] In use, the heat exchanger assembly equipment employs a support member 1 to arrange multiple fins 100 extending in the left-right direction, with the fins 100 spaced apart in the front-back direction. A first pressing part 2 is used to arrange multiple heat exchange tubes 200 extending in the front-back direction. The support member 1 moves to a position where it is spaced apart from the first pressing part 2 in the vertical direction. The multiple heat exchange tubes 200 are then aligned one-to-one with multiple slotted holes 11. The first pressing part 2 and the support member 1 then move relative to each other, causing the multiple heat exchange tubes 200 to pass through the slotted holes 11 one-to-one and be pressed into place with the fins 100. This assembly method reduces bending or deformation of the fins 100 during assembly, thereby improving the assembly effect between the fins 100 and the heat exchange tubes 200.

[0027] In some embodiments, the second component further includes a second pressing part 3, which is arranged at a distance from the first pressing part 2. The first pressing part 2 and the second pressing part 3 are capable of operating in a third direction (e.g., Figure 1 The support member 1 can move relative to the first pressing part 2 and be located between the first pressing part 2 and the second pressing part 3. The third direction is perpendicular to the first and second directions.

[0028] like Figures 1-4As shown, the second component further includes a horizontally arranged second pressing part 3, which is arranged vertically spaced from the first pressing part 2 and located above the first pressing part 2. Preferably, the second component also includes a first frame 9 and a second frame 10, with the first frame 9 located inside the second frame 10. The first pressing part 2 is located on top of the first frame 9, and the second pressing part 3 is located on top of the second frame 10 and inside the second frame 10, so that the second pressing part 3 is located above and facing the first pressing part 2. At least one of the first pressing part 2 and the second pressing part 3 is movable in the vertical direction, so that the first pressing part 2 and the second pressing part 3 can move relative to each other in the vertical direction.

[0029] The support member 1 can move between a first position and a second position relative to the first pressing part 2 and the second pressing part 3 in the front-back direction. In the first position, the support member 1 is located between the first pressing part 2 and the second pressing part 3. In the second position, the support member 1 is located outside the space between the first pressing part 2 and the second pressing part 3. In other words, the support member 1 and the space between the first pressing part 2 and the second pressing part 3 are spaced apart in the front-back direction. Figure 1 As shown.

[0030] When the heat exchanger assembly equipment is in use, the support member 1 is loaded at the second position; in other words, multiple fins 100 are placed on the support member 1 at the second position. Then, the support member 1 carries the multiple fins 100 to the first position, where the second pressing part 3 abuts against the top of the fins 100 to secure them to the support member 1 and prevent movement during pressing. Both the support member 1 and the second pressing part 3 move downwards, or the first pressing part 2 moves upwards, so that the multiple heat exchange tubes 200 carried by the first pressing part 2 pass through the slot 11 and are pressed into place with the fins 100.

[0031] It should be noted that the pressed-fit fins 100 and heat exchange tubes 200 can be unloaded from between the first pressing part 2 and the second pressing part 3 in a direction away from the second position, or they can be supported by the support member 1 and moved to the second position, and then unloaded from the second position. Preferably, unloading is performed between the first pressing part 2 and the second pressing part 3 in a direction away from the second position. This document does not specifically limit the unloading position and method.

[0032] In some embodiments, the second component includes a first drive mechanism 4, and the second pressing part 3 includes a pressing mechanism 31 and a gripping mechanism 32. The first drive mechanism 4 is connected to the pressing mechanism 31 and is capable of driving the pressing mechanism 31 to move in a third direction. The pressing mechanism 31 has a pressing surface 311 that can cover at least a portion of the support member 1. The gripping mechanism 32 is directly or indirectly connected to the pressing mechanism 31. The gripping mechanism 32 is capable of moving at least partially relative to the pressing mechanism 31 in a third direction, and the gripping mechanism 32 is capable of gripping and releasing the support member 1.

[0033] like Figures 1-3 As shown, a first drive mechanism 4 is provided on the top of the second frame 10. The first drive mechanism 4 is preferably, but not limited to, four. The first drive mechanism 4 is vertically arranged and can extend and retract in the vertical direction. The top of the first drive mechanism 4 is connected to the second frame 10, and the bottom is connected to the pressing mechanism 31 of the second pressing part 3, so as to drive the pressing mechanism 31 to move vertically relative to the second frame 10. The first drive mechanism 4 is preferably, but not limited to, a telescopic cylinder, a telescopic electric cylinder, etc.

[0034] The pressing mechanism 31 includes a horizontally arranged pressing plate 314 and a connecting frame 315. The pressing plate 314 is located at the bottom of the connecting frame 315. The top of the connecting frame 315 is connected to the bottom of the first drive mechanism 4. The bottom surface of the pressing plate 314 forms a pressing surface 311. The pressing surface 311 can cover all or part of the support member 1 so that it abuts against the top of multiple fins 100 on the support member 1 under the drive of the first drive mechanism 4, thereby fixing the position of the multiple fins 100 on the support member 1.

[0035] A frame guide rail 20 is provided between the connecting frame 315 and the second frame 10. The frame guide rail 20 is preferably, but not limited to, two sets arranged at intervals along the left and right direction. Each set of frame guide rails 20 includes two frame guide rails 20 arranged at intervals along the front and back direction. The frame guide rail 20 is located on the top of the second frame 10 and has an extension. The connecting frame 315 is connected to the frame guide rail 20 and can move along the frame guide rail 20. The frame guide rail 20 is used to guide the connecting frame 315 and the lower pressure plate 314 to move stably in the vertical direction.

[0036] The gripping mechanism 32 of the second pressing section 3 is connected to the connecting frame 315 and is at least partially movable vertically relative to the connecting frame 315 and the lower pressure plate 314. The bottom of the gripping mechanism 32 can move below the lower pressure plate 314 for gripping and releasing the support member 1. Specifically, the gripping mechanism 32 includes a lifting assembly 321 and a gripper assembly 322. The lifting assembly 321 extends vertically and is disposed on the connecting frame 315. The gripper assembly 322 is connected to the lifting assembly 321 and moves vertically under the drive of the lifting assembly 321. The bottom of the gripper assembly 322 can move below the lower pressure plate 314; in other words, the bottom of the gripper assembly 322 can move to a position below the lower pressure surface 311. The gripper assembly 322 is used to grip and release the support member 1.

[0037] The lifting assembly 321 is preferably, but not limited to, two sets arranged at intervals along the front-to-back direction. Each set of lifting assemblies 321 includes two lifting assemblies 321 arranged at intervals along the left-to-right direction. One set of lifting assemblies 321 is located at the front end of the connecting frame 315, and the other set of lifting assemblies 321 is located at the rear end of the connecting frame 315. The lower pressure plate 314 is located between the two sets of lifting assemblies 321. Each lifting assembly 321 is connected to a corresponding gripper assembly 322.

[0038] The lifting assembly 321 preferably includes, but is not limited to, a guide rail, gears, a rack, and a rotating motor. The rotating motor of the lifting assembly 321 is located on the connecting frame 315 and connected to the gear of the lifting assembly 321. The guide rail of the lifting assembly 321 is vertically arranged on the connecting frame 315 and connected to the gripper assembly 322. The gripper assembly 322 has a vertically arranged rack that meshes with the gear. It is understood that in other embodiments, the lifting assembly 321 may also be a telescopic cylinder, a telescopic electric cylinder, a guide rail, a ball screw, a linear module, etc. In addition, the gripper assembly 322 is preferably, but not limited to, a pneumatic gripper, an electric gripper, a robotic arm, etc.

[0039] When the heat exchanger assembly equipment is in use, the first drive mechanism 4 drives the lower pressure plate 314 and the connecting frame 315 to move downward, so that the lower pressure surface 311 presses against the top of the multiple fins 100. Then, the lifting assembly 321 drives the gripper assembly 322 to move downward and grab the support member 1 located in the first position, so that the lower pressure surface 311 and the support member 1 cooperate to clamp and fix the position of the multiple fins 100 on the support member 1.

[0040] The first drive mechanism 4 drives the pressing mechanism 31 and the gripping support 1 to move downwards; in other words, the first drive mechanism 4 drives the pressing mechanism 31 and the gripping support 1 to move towards the first pressing part 2. The multiple heat exchange tubes 200 supported by the first pressing part 2 pass through the strip hole 11 and are pressed into the fins 100. After pressing is completed, the gripper assembly 322 releases the support 1, and the assembled fins 100 and heat exchange tubes 200 are unloaded.

[0041] In some embodiments, the pressing mechanism 31 further includes a second driving mechanism 312 and a pressure plate 313. The second driving mechanism 312 is connected to the pressure plate 313, which is located on the side of the pressing surface 311 facing the first pressing part 2. The length direction of the pressure plate 313 extends along a second direction. There are at least two pressure plates 313, which are spaced apart along the first direction. The second driving mechanism 312 can drive at least a portion of the pressure plates 313 to move relative to each other along the first direction. The pressure plate 313 has a plurality of clearance grooves 3131, which are spaced apart along the length direction of the pressure plate 313.

[0042] like Figure 4 As shown, the pressing mechanism 31 also includes a second driving mechanism 312 and a pressure plate 313. The second driving mechanism 312 is installed on the top of the pressing plate 314. The pressure plate 313 is located on the lower side of the pressing surface 311 and is preferably a strip that extends in the left and right direction and is vertically arranged. The bottom surface of the pressure plate 313 is provided with a plurality of clearance grooves 3131 arranged at intervals in the left and right direction.

[0043] The lower pressure plate 314 has an elongated hole that extends in the front-back direction and passes through it in the vertical direction. The pressure plate 313 has an upwardly extending protrusion that passes through the elongated hole into the lower pressure plate 314 and is connected to the second drive mechanism 312, so that the second drive mechanism 312 can drive the pressure plate 313 to move relative to the lower pressure plate 314 in the front-back direction.

[0044] The pressure plate 313 preferably, but not limited to, has two protrusions spaced apart in the left-right direction. The two protrusions can be connected to the same second drive mechanism 312, or they can be connected to different second drive mechanisms 312, and the two second drive mechanisms 312 operate synchronously. Therefore, the pressure plate 313 moves under the drive of the second drive mechanism 312 connected to it. Multiple pressure plates 313 can all be stationary, all of them can move, or some can be stationary and some can move. The moving pressure plates 313 can also move in the same direction or in opposite directions.

[0045] The pressure plate 313 is configured to be at least two arranged at intervals along the front-back direction. The fins 100 supported by the support member 1 can be in the same group, or can be divided into two groups arranged in the left-right direction, or can be divided into three or more groups arranged in the left-right direction. Each group of fins 100 includes multiple fins 100 arranged at intervals. The distance between two adjacent groups of fins 100 is greater than the distance between two adjacent fins 100 in the same group.

[0046] After the gripper assembly 322 grasps the carrier 1, each of the two outermost fins 100 in each group of fins 100 is provided with a corresponding pressure plate 313 on its outer side in the front-rear direction. The two pressure plates 313 move closer to each other to abut against the outermost fins 100, thereby limiting the two outermost fins 100. During the pressing process of the fins 100 and the heat exchange tube 200, since the two outermost fins 100 are limited by the pressure plates 313, and the slots of the heat exchange tube 200 and the fins 100 are arranged in a one-to-one correspondence, the two pressure plates 313 cooperate with the heat exchange tube 200 to apply a pressing force to the multiple fins 100 in the group, so as to ensure the pressing effect. At the same time, it can avoid the problems of excessive pressing force on the fins 100 leading to deformation and adhesion, and insufficient pressing force on the fins 100 leading to falling off, which are common in related technologies. Multiple clearance slots 3131 are provided one-to-one with multiple heat exchange tubes 200 to prevent the heat exchange tubes 200 from interfering with the pressure plate 313 when inserted, which would cause damage or deformation to the heat exchange tubes 200.

[0047] Preferably, four pressure plates 313 are arranged at intervals. When the fins 100 supported by the support member 1 are in the same group, the two pressure plates 313 in the middle are stationary, and the pressure plates 313 at both ends move relative to each other to apply a clamping force to the fins 100. When the fins 100 supported by the support member 1 are divided into two groups, the left group of fins 100 is located between the two left pressure plates 313, and the right group of fins 100 is located between the two right pressure plates 313, so that they are respectively clamped by the corresponding two pressure plates 313. Therefore, heat exchangers with various arrangements of fins 100 can be press-fitted, such as heat exchangers with a middle section that does not contain fins.

[0048] The second drive mechanism 312 is preferably, but not limited to, a gear rack driven by a rotary motor, wherein the rack extends in the front-to-back direction and is connected to the protrusion. It is understood that in other embodiments, the second drive mechanism 312 may also be a telescopic cylinder, a telescopic electric cylinder, a guide rail and ball screw, a linear module, etc.

[0049] In some embodiments, the first component further includes a third drive mechanism 5 and a first table 6, the first table 6 being able to support the support member 1, the third drive mechanism 5 being connected to the first table 6 and being able to drive the first table 6 to move relative to the first pressing part 2.

[0050] like Figure 1 , Figure 2 and Figure 5 As shown, the first component also includes a third drive mechanism 5 and a first platform 6. The first platform 6 is horizontally arranged and disposed on the second frame 10, and the first platform 6 can move in the front-back direction relative to the second frame 10. The third drive mechanism 5 is connected between the second frame 10 and the first platform 6 to drive the first platform 6 to move in the front-back direction. The support member 1 is supported on the first platform 6.

[0051] Preferably, both ends of the first platform 6 are connected to slide rails provided on the second frame 10 and extending in the front-back direction. At least one end of the first platform 6 in the left-right direction is provided with a third drive mechanism 5. The third drive mechanism 5 is preferably a gear and rack driven by a rotary motor. The rotary motor and gear are provided on the first platform 6, and the rack extends in the front-back direction and is provided on the second frame 10. It is understood that in other embodiments, the third drive mechanism 5 can also be a telescopic cylinder, a telescopic electric cylinder, a guide rail and a ball screw, a linear module, etc. The first platform 6 is used to support the support member 1 and, driven by the third drive mechanism 5, drives the support member 1 to move smoothly in the front-back direction so as to enter and exit the space between the first pressing part 2 and the second pressing part 3.

[0052] In some embodiments, the first component further includes at least two inserts 7, which are spaced apart along a second direction on the first platform 6. When the support member 1 is located on the first platform 6, the inserts 7 can pass through the strip hole 11 and be located within the support member 1. Figure 1 , Figure 2 and Figure 5 As shown, the first tabletop 6 is provided with at least two inserts 7 that are vertically arranged and extend in the front-back direction, preferably but not limited to three, and the three inserts 7 are arranged at intervals in the left-right direction.

[0053] When the support member 1 is located on the first platform 6, the three inserts 7 pass through the strip hole 11 of the support member 1, and the top of the insert 7 is higher than the support member 1. The fins 100 are inserted into the three inserts 7 in the left and right directions. Multiple fins 100 are arranged at intervals in the front and back directions on the three inserts 7. At this time, the position of multiple fins 100 can be limited when the inserts 7 are used to feed the fins 100.

[0054] When the heat exchanger assembly equipment is in use, the first drive mechanism 4 drives the lower pressure plate 314 and the connecting frame 315 to move downward, so that the lower pressure surface 311 presses against the top of multiple fins 100. Then, the lifting assembly 321 drives the gripper assembly 322 to move downward and grab the support member 1 located in the first position. After the gripper assembly 322 grabs the support member 1, the lifting assembly 321 drives the gripper assembly 322 to move upward, and when the gripped support member 1 moves upward, the support member 1 disengages from the first table 6 and supports multiple fins 100. At this time, the lower pressure surface 311 cooperates with the support member 1 to limit the position of multiple fins 100 and prevent the fins 100 from moving inside the support member 1 after disengaging from the insert 7.

[0055] In some embodiments, the support member 1 includes a base plate 12 and a side plate 13, the side plate 13 being disposed on opposite sides of the base plate 12, the strip hole 11 being located on the base plate 12, and the two ends of the strip hole 11 extending to the side plate 13 on both sides of the base plate 12 respectively.

[0056] like Figure 6 As shown, the support component 1 includes a base plate 12 and side plates 13. The base plate 12 is horizontally arranged, and both the front and rear ends of the base plate 12 are provided with upwardly extending side plates 13. The height of the strip-shaped hole 11 is lower than the height of the side plates 13. The strip-shaped hole 11 penetrates the base plate 12 and the side plates 13 at both ends in the front-rear direction. In other words, the strip-shaped hole 11 extends from the lower part of the front side plate 13 through the base plate 12 to the lower part of the rear side plate 13. The top of the two side plates 13 is used to be gripped by the gripper assembly 322. The lower part of the side plates 13 is provided with the strip-shaped hole 11 to ensure that the position of the heat exchange tube 200 is limited during the pressing process, so as to ensure that the heat exchange tube 200 and the fins 100 are accurately pressed together.

[0057] In some embodiments, the second component further includes a fourth drive mechanism 8, and the first pressing part 2 includes a comb tooth frame 21. The fourth drive mechanism 8 is directly or indirectly connected to the comb tooth frame 21, and the fourth drive mechanism 8 is capable of driving the comb tooth frame 21 to move in a third direction. The comb tooth frame 21 includes a first comb tooth plate 211 and a fifth drive mechanism 212. The fifth drive mechanism 212 is connected to the first comb tooth plate 211, and the fifth drive mechanism 212 is capable of driving the first comb tooth plate 211 to move in a third direction.

[0058] like Figure 5 As shown, a fourth drive mechanism 8 is provided on the top of the first frame 9. The fourth drive mechanism 8 is preferably, but not limited to, four. These four fourth drive mechanisms 8 are connected to the comb frame 21 of the first pressing part 2 to drive the comb frame 21 to move vertically relative to the first frame 9. The comb frame 21 supports multiple heat exchange tubes 200 extending in the front-to-back direction and spaced apart in the left-to-right direction, so that they move towards the second pressing part 3 under the drive of the fourth drive mechanisms 8, thereby pressing the fins 100 and the heat exchange tubes 200 together. The fourth drive mechanism 8 is preferably, but not limited to, a telescopic electric cylinder, a telescopic pneumatic cylinder, etc.

[0059] The comb frame 21 includes a base, a first comb plate 211 and a fifth drive mechanism 212. The first comb plate 211 extends in the left-right direction and is located on the top of the base. The fifth drive mechanism 212 is connected between the base and the first comb plate 211 to drive the first comb plate 211 to move in the vertical direction relative to the base.

[0060] When feeding the heat exchange tubes 200, the fifth drive mechanism 212 drives the first comb plate 211 to rise. The fed heat exchange tubes 200 need to pass through the teeth of the first comb plate 211 to define the positions of multiple heat exchange tubes 200, thereby ensuring precise pressing of the heat exchange tubes 200 and fins 100. When pressing the fins 100 and heat exchange tubes 200 together, the fifth drive mechanism 212 drives the first comb plate 211 to descend to avoid interference between the fins 100 and the first comb plate 211, which could affect the assembly effect and damage the fins 100. The fifth drive mechanism 212 is preferably, but not limited to, a telescopic electric cylinder, a telescopic pneumatic cylinder, etc.

[0061] In some embodiments, the comb frame 21 further includes at least two second comb plates 213, which are located on both sides of the first comb plate 211 along the width direction, and the second comb plates 213 are movable relative to the first comb plate 211.

[0062] like Figure 5 As shown, the comb frame 21 also includes a second comb plate 213, which extends in the left-right direction and is located on the top of the base. The second comb plate 213 is preferably, but not limited to, two arranged at intervals in the front-back direction. The first comb plate 211 is located between the second comb plates 213 and moves between a position flush with the first comb plate 211 and a position lower than the first comb plate 211 under the drive of the fifth drive mechanism 212.

[0063] The heat exchange tube 200 is simultaneously inserted into the grooves of two second comb plates 213 to fix the heat exchange tube 200. Preferably, both ends of the heat exchange tube 200 are respectively inserted into the grooves of the corresponding second comb plates 213. The first comb plate 211 is used to define the position of the middle part of the heat exchange tube 200. Furthermore, the second comb plate 213 can move relative to the base in the front-back direction to accommodate heat exchange tubes 200 of various lengths.

[0064] In some embodiments, the comb frame 21 further includes at least one support base 214, which is located between the first comb plate 211 and at least one second comb plate 213. The support base 214 has a plurality of ribs 2141, which are spaced apart along the length of the support base 214.

[0065] like Figure 5 and Figure 7 As shown, the top of the base is also provided with several support seats 214 extending in the left-right direction. Preferably, each second comb plate 213 and the first comb plate 211 are provided with a support seat 214. The top surface of the support seat 214 is provided with a plurality of protruding ribs 2141 extending in the front-back direction. The plurality of protruding ribs 2141 are arranged at intervals in the left-right direction to support the heat exchange tubes 200 one by one. The height of the protruding ribs 2141 is greater than or equal to the thickness of the base plate 12, so that during the pressing process, they can extend through the strip hole 11 to the top of the base plate 12 or be flush with the top surface of the base plate 12, thereby pressing the heat exchange tubes 200 into the slots of the fins 100, so that the heat exchange tubes 200 are flush with or lower than the fins 100.

[0066] The second aspect of this application provides a heat exchanger assembly method. For example... Figures 1-7 As shown, the heat exchanger assembly method of this application embodiment includes the following steps:

[0067] Multiple fins 100 are arranged on the support member 1, and multiple heat exchange tubes 200 are arranged on the first pressing part 2. For example, Figure 2 and Figure 5 As shown, multiple fins 100 extending in the left-right direction are arranged at intervals in the front-back direction on the support member 1, and multiple heat exchange tubes 200 extending in the front-back direction are arranged at intervals in the left-right direction on the first pressing part 2.

[0068] The movable support 1 and / or the first pressing part 2 are moved such that the heat exchange tube 200 passes through the strip hole 11 on the support 1 and enters the support 1, with the heat exchange tube 200 at least partially inserted into the slot of the fin 100. For example, as Figure 2 As shown, either the drive support member 1 or the first pressing part 2 moves vertically so that the heat exchange tube 200 on the first pressing part 2 passes upward through the strip hole 11 of the support member 1 and is at least partially inserted into the slot of the fin 100 supported by the support member 1, so that the heat exchange tube 200 is pressed into the fin 100.

[0069] The heat exchanger assembly method of this application embodiment arranges the fins of the heat exchanger on the support member and arranges the heat exchange tubes of the heat exchanger on the first pressing part. By moving the support member and the first pressing part relative to each other, the heat exchange tubes of the heat exchanger pass through the strip hole of the support member and the heat exchange tubes of the heat exchanger are pressed together with the fins of the heat exchanger. Therefore, the heat exchanger assembly method of this application embodiment has excellent assembly effect.

[0070] In some embodiments, the heat exchanger assembly method of this application further includes the following steps:

[0071] The strip hole 11 of the support member 1 is passed through the insert 7 and placed on the first platform 6. The fins 100 are arranged on the support member 1 through the insert 7.

[0072] like Figure 2 and Figure 5 As shown, the support member 1 is placed on the first platform 6, and the insert 7 on the first platform 6 passes through the strip hole 11 and is higher than the support member 1. Then, the fins 100 are inserted into the three inserts 7 in the left-right direction, and the multiple fins 100 are arranged at intervals on the three inserts 7 in the front-back direction.

[0073] Move the first tabletop 6 between the first pressing part 2 and the second pressing part 3.

[0074] like Figure 1 and Figure 2 As shown, the first platform 6 is driven by the third drive mechanism 5 to move the first frame 9 in the front-back direction to between the first pressing part 2 and the second pressing part 3 arranged at intervals in the vertical direction.

[0075] Drive the second pressing part 3 so that the lower pressing surface 311 of the second pressing part 3 presses onto the fin 100, drive the gripping mechanism 32 of the second pressing part 3 to grip the carrier 1, move the second pressing part 3 so that the carrier 1 separates from the insert 7.

[0076] like Figures 1-4 As shown, the second pressing part 3 is driven by the first driving mechanism 4 to move downward at the top of the second frame 10 so that the lower pressing surface 311 of the lower pressing plate 314 presses against the multiple fins 100. The lifting assembly 321 drives the gripper assembly 322 to move downward so that the bottom of the gripper assembly 322 moves below the lower pressing plate 314 and the gripper assembly 322 grabs the support member 1. Then the lifting assembly 321 drives the gripper assembly 322 to move upward so that the support member 1 supports the multiple fins 100. The second pressing part 3 is then driven upward by the first driving mechanism 4 so that the support member 1 and the multiple fins 100 are separated from the insert 7.

[0077] Move the first platform 6 to a preset position, drive the first pressing part 2 and / or the second pressing part 3 to move relative to each other, so that the heat exchange tube 200 is inserted into the fin 100.

[0078] like Figure 1 and Figure 2 As shown, the first platform 6 is driven to move along the front-back direction of the first frame 9 by the third drive mechanism 5, so that the first platform 6 moves to a preset position outside the space between the first pressing part 2 and the second pressing part 3. Then, the second pressing part 3 is driven to move downward by the first drive mechanism 4, and the comb frame 21 of the first pressing part 2 is driven to move upward by the fourth drive mechanism, so that the heat exchange tube 200 passes through the strip hole 11 and is inserted into the slot of the fin 100, thereby pressing the heat exchange tube 200 onto the fin 100.

[0079] It is understood that in other embodiments, the second pressing part 3 can be moved downward by the first driving mechanism 4 and the comb tooth frame 21 of the first pressing part 2 can be stationary, or the comb tooth frame 21 of the first pressing part 2 can be moved upward by the fourth driving mechanism and the second pressing part 3 can be stationary, so that the heat exchange tube 200 passes through the strip hole 11 and is inserted into the slot of the fin 100, thereby pressing the heat exchange tube 200 onto the fin 100.

[0080] In some embodiments, the steps further include the following steps before the heat exchange tube 200 is inserted into the fins 100.

[0081] The pressure plate 313 of the second pressing part 3 is moved so that it is located on both sides of the plurality of fins 100, and the pressure plate 313 is moved to clamp the plurality of fins 100. Alternatively, the pressure plate 313 of the second pressing part 3 is moved so that a portion of the pressure plate 313 is located on both sides of the plurality of fins 100 and another portion of the pressure plate 313 is located between the plurality of fins 100, and the pressure plate 313 is moved to clamp the fin 100 between two opposing pressure plates 313.

[0082] like Figure 4 As shown, the fins 100 supported by the carrier 1 can be in the same group or divided into two groups arranged in the left-right direction. After the gripper assembly 322 grasps the carrier 1, the outermost two fins 100 in each group of fins 100 in the front-rear direction are provided with corresponding pressure plates 313. The two pressure plates 313 are driven to move closer to each other to abut against the outermost fins 100, thereby limiting the two outermost fins 100 and clamping the multiple fins 100 in the same group.

[0083] In some embodiments, the heat exchange tube 200 is arranged in the first press-fit section 2, and the following steps are also included:

[0084] Adjust the distance between the two furthest second comb plates 213 of the first pressing part 2 so that the two ends of the heat exchange tube 200 are respectively located on the second comb plates 213 on both sides, drive the first comb plate 211 to move relative to the first pressing part 2, and arrange multiple heat exchange tubes 200 on the first comb plate 211 and the second comb plate 213.

[0085] like Figure 5 As shown, the second comb plate 213 at the foremost and / or rearmost end on the drive base moves in the front-back direction to adjust the distance between the foremost and rearmost second comb plates 213. The first comb plate 211 is driven to move upward and become flush with the second comb plate 213 by the fifth drive mechanism 212. Then, the heat exchange tube 200 is placed and its two ends are inserted into the tooth grooves of the foremost and rearmost second comb plates 213, respectively, and the middle part of the heat exchange tube 200 is inserted into the tooth groove of the first comb plate 211.

[0086] When the heat exchange tube 200 passes through the support member 1 and enters the support member 1, the first comb plate 211 is driven to move a preset distance toward the side away from the support member 1.

[0087] like Figure 5As shown, during the process of the first driving mechanism 4 driving the second pressing part 3 to move downward and the fourth driving mechanism driving the comb tooth frame 21 of the first pressing part 2 to move upward, so that the heat exchange tube 200 passes through the strip hole 11 and is inserted into the slot of the fin 100, the fifth driving mechanism 212 drives the first comb tooth plate 211 to move downward by a preset distance to avoid interference between the fin 100 and the first comb tooth plate 211.

[0088] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
