Mode for Carrying Out the Invention

[0033] One embodiment disclosed in this specification will be described in detail below, and an example thereof is shown in the drawings. The embodiments described with reference to the attached drawings below are exemplary and are for explaining the present application and should not be construed as a limitation of the present application.

[0034] As shown in FIG. 1, the processing apparatus 100 for a heat exchanger according to an embodiment of the present application includes a platform 1.

[0035] The platform 1 includes position regulating components 2. The position regulating components 2 protrude from the platform 1. There are a plurality of position regulating components 2. The plurality of position regulating components 2 are installed at intervals along a first direction (for example, the front-rear direction shown in FIG. 2), and the plurality of position regulating components 2 are installed at intervals along a second direction (for example, the left-right direction shown in FIG. 2).

[0036] The platform 1 includes a first platform 11, a second platform 12, and a third platform 13 provided along the second direction. The second platform 12 is located between the first platform 11 and the third platform 13. The first platform 11 and the third platform 13 are movable along the second direction, and the second platform 12 is movable along the first direction. The heat exchanger is a microchannel heat exchanger. The minimum distance between two adjacent position regulating components 2 in the first direction is greater than the thickness of the heat exchange tube 201 of the microchannel heat exchanger to be processed.

[0037] Specifically, as shown in FIG. 1, the platform 1 includes a first platform 11, a second platform 12, and a third platform 13 that are installed at intervals along the left - right direction. A position - regulating component 2 is provided on the platform 1. Here, on the first platform 11 and the third platform 13, a first position - regulating component 21 is installed. The first position - regulating component 21 is used to regulate the heat - exchange tube 201 so that the heat - exchange tube 201 is fixed to the platform 1. A second position - regulating component 22 is provided on the second platform 12. The second position - regulating component 22 is used to push the heat - exchange tube 201. The second platform 12 is movable along the front - rear direction, and the second platform 12 moves the second position - regulating component 22 so that the second position - regulating component 22 pushes the heat - exchange tube 201.

[0038] As shown in FIGS. 1 to 3, the processing device 100 for a heat exchanger according to an embodiment of the present application includes a platform 1.

[0039] The platform 1 includes a position - regulating component 2. The platform 1 includes a plurality of concave grooves (not shown). The concave grooves extend along a second direction, and the plurality of concave grooves are installed at intervals along a first direction.

[0040] The platform 1 includes a first platform 11, a second platform 12, and a third platform 13 provided along the second direction. The second platform 12 is located between the first platform 11 and the third platform 13. The first platform 11, the second platform 12, and the third platform 13 all include concave grooves. The first platform 11 and the third platform 13 are movable along the second direction, and the second platform 12 is movable along the first direction. The heat exchanger is a micro - channel heat exchanger, and the minimum dimension of the concave groove in the first direction is larger than the thickness of the heat - exchange tube 201 of the micro - channel heat exchanger to be processed.

[0041] Note that the heat exchange tube 201 can be installed in the concave groove. In this application, by fixing the heat exchange tube 201 to the platform 1 through the single use or combined action of the position regulating component 2 and the concave groove, the force received by the heat exchange tube 201 during movement is made more stable, and the stress concentration on the heat exchange tube 201 is effectively reduced. In some embodiments, the platform 1 further includes a concave groove (not shown), the concave groove extends along a second direction, a plurality of concave grooves are arranged at intervals along a first direction, the first platform 11 includes a concave groove, and / or the second platform 12 includes a concave groove.

[0042] Note that the concave groove can be installed on the first platform 11 and / or the second platform 12 and / or the third platform 13. Here, when the concave groove is provided on any of the first platform 11, the second platform 12, and the third platform 13, the processing device 100 of the heat exchanger in this application has the highest restricting effect on the heat exchange tube 201.

[0043] Note that a material with a relatively low surface hardness, such as a resin material, can be used on the surface of the position regulating component 2 that contacts the heat exchange tube 201, which can reduce the wear on the heat exchange tube 201. The surface where the concave groove and the heat exchange tube 201 may come into contact includes a material with a relatively low hardness, such as resin, which can protect the heat exchange tube 201.

[0044] As shown in FIGS. 13 to 15, the processing device 100 for the heat exchanger according to the embodiment of this application includes a second platform 12, and the second platform 12 includes a first component 121 and a plurality of second position regulating components 22.

[0045] The plurality of second position regulating components 22 are provided on the first component 121, and the plurality of second position regulating components 22 are arranged at intervals along the length direction of the first component 121.

[0046] The heat exchanger is a microchannel heat exchanger, and the microchannel heat exchanger includes a plurality of heat exchange tubes 201. During the operation of the second platform 12, one heat exchange tube 201 can be arranged between two second position regulating components 22 adjacent to each other in the length direction of the first component 121 (for example, the front-back direction shown in FIG. 1). The length direction of the first component 121 and the length direction of the heat exchange tube 201 (for example, the left-right direction shown in FIG. 1) form an angle, and the angle is not zero.

[0047] The distance between two second position regulating components 22 adjacent to each other in the length direction of the first component 121 is L1, the width of the second position regulating component 22 is B, and the condition B > 0.2L1 is satisfied.

[0048] The processing device 100 for the heat exchanger according to the embodiment of the present application includes at least one second platform 12, and the second platform 12 includes a first component 121 and a plurality of second position regulating components 22. Here, the first component 121 is substantially flat-plate-shaped, and the plurality of second position regulating components 22 are uniformly and spaced along the length direction of the first component 121 on the plane of the first component 121. The plurality of second position regulating components 22 can be inserted between adjacent heat exchange tubes 201 in a one-to-one correspondence. By moving the second platform 12, the plurality of second position regulating components 22 can move the heat exchange tubes 201. The processing device 100 for the heat exchanger according to the embodiment of the present application helps to reduce the pressing force during the processing of the heat exchange tubes 201, reduce stress concentration, increase the strength of the heat exchange tubes 201, and reduce the non-uniformity of the shape of the bending region. The fact that the shapes of the bending regions of the heat exchanger are consistent is advantageous for subsequent processing and helps to form a gap of a considerable size between adjacent heat exchange tubes 201 in the bending region.

[0049] As shown in FIGS. 13 to 16, a specific implementation process of the processing device 100 for the heat exchanger according to the embodiment of the present application is as follows.

[0050] The second platform 12 is moved upward from below the heat exchanger so that a plurality of second position restricting components 22 of the second platform 12 are sequentially inserted between adjacent heat exchange tubes 201. The second platform 12 extends in the front-rear direction, the heat exchange tubes 201 extend in the left-right direction, and the length direction of the second platform 12 is substantially orthogonal to the length direction of the heat exchange tubes 201.

[0051] When the second platform 12 is moved backward from the front in the front-rear direction, the second position restricting component 22 gradually comes into contact with the heat exchange tube 201, and the second position restricting component 22 gradually pushes a partial tube segment of the heat exchange tube 201 in the front-rear direction, moving the partial tube segment by a preset distance with respect to the remaining tube segments of the heat exchange tube 201.

[0052] In some embodiments, as shown in FIGS. 13 to 16, when the second platform 12 operates, the heat exchange tube 201 includes a first tube segment 2011, a second tube segment 2012, and a third tube segment 2013, and the first tube segment 2011 is located between the second tube segment 2012 and the third tube segment 2013 in the length direction of the heat exchange tube 201.

[0053] The heat exchanger further includes a first fin and a second fin. The first fin is connected to the second tube segment 2012, the second fin is connected to the third tube segment 2013, and the first tube segment 2011 is located between the first fin and the second fin in the length direction of the heat exchange tube 201.

[0054] The length of the first tube segment is A, the distance between two adjacent heat exchange tubes 201 in the length direction of the first component 121 is L2, and the conditions B≤0.7A and / or L1≤L2 are satisfied.

[0055] It should be noted that B, A, L1, and L2 are It satisfies the conditions of B > 0.2L1 and B ≤ 0.7A, or B > 0.2L1 and L1 ≤ L2, or B > 0.2L1, B ≤ 0.7A and L1 ≤ L2. Here, because L1 ≤ L2, the interval between the second position regulating parts 22 and the interval between the adjacent heat exchange tubes 201 are substantially the same. When the second position regulating parts 22 are inserted between the adjacent heat exchange tubes 201, they will not cause damage or friction to the heat exchange tubes 201. At the same time, during processing, the heat exchange tubes 201 can move in their length direction, reducing excessive deformation of the heat exchange tubes 201 in the bending region, which is beneficial to improving the reliability of the heat exchange tubes 201.

[0056] In some embodiments, the width of the heat exchange tube 201 is Tw (not shown in the figure), the height of the second position regulating part 22 is H, and it satisfies the condition of H ≥ 0.25Tw. Thereby, the contact area between the second position regulating part 22 and the heat exchange tube 201 is effectively improved, the unit pressure received by the heat exchange tube 201 is reduced, the force received by the heat exchange tube 201 during translation becomes more stable, it is less likely for the heat exchange tube 201 to twist or slip, and at the same time, it is avoided that the second position regulating part 22 causes frictional damage to the heat exchange tube 201.

[0057] In some embodiments, as shown in FIGS. 13 to 16, the thickness of the heat exchange tube 201 is t, the tooth thickness of the second position regulating part 22 is T, and it satisfies the condition of T < L1 - t. Thereby, it becomes easier for the second position regulating part 22 to be inserted between the adjacent heat exchange tubes 201, and the probability of collision between the second position regulating part 22 and the heat exchange tube 201 is effectively reduced.

[0058] In some embodiments, as shown in FIGS. 19 to 21, the second position regulating part 22 includes a cylindrical part 31 and a frustum - shaped conical part 32, and the frustum - shaped conical part 32 is installed farther away from the first part 121 than the cylindrical part 31.

[0059] Specifically, as shown in FIGS. 19 to 20, the second position regulating component 22 is substantially cylindrical, and since the insertion end of the second position regulating component 22 has a frustum of a cone structure, when the second position regulating component 22 is inserted between adjacent heat exchange tubes 201, the friction between the frustum of a cone portion 32 of the second position regulating component 22 and the heat exchange tube 201 becomes smaller, and the damage to the heat exchange tube 201 caused by the friction of the second position regulating component 22 is effectively reduced.

[0060] In some embodiments, as shown in FIG. 21, the insertion end of the second position regulating component 22 is conical or frustum-shaped, whereby it becomes easier to insert the second position regulating component 22 between adjacent heat exchange tubes 201. The surface of the heat exchange tube 201 may be coated with a coating such as a hydrophilic coating or an anticorrosion coating. By making the insertion end of the second position regulating component 22 conical or frustum-shaped, damage to the surface coating of the heat exchange tube 201 can be reduced.

[0061] In some embodiments, as shown in FIGS. 22 to 23, the second position regulating component 22 includes a first portion 33 and a second portion 34 installed along its height direction. The second portion 34 is connected to the first component 121, the first portion 33 is installed farther from the first component 121 than the second portion 34, the thickness of the first portion 33 is T1, the thickness of the second portion 34 is T2, and the thickness of the second portion 34 is greater than the thickness of the first portion 33.

[0062] Note that T1 ≤ T, whereby the first portion 33 of the second position regulating component 22 can be normally inserted between adjacent heat exchange tubes 201.

[0063] The fact that the thickness of the second portion 34 is greater than the thickness of the first portion 33 is advantageous for enhancing the connection stability between the second position regulating component 22 and the first component 121.

[0064] In some embodiments, as shown in FIGS. 24 to 25, the cross-section of the second position regulating component 22 is elliptical, or the outer ring of the cross-section of the second position regulating component 22 includes an arc portion. Thereby, when the second position regulating component 22 and the heat exchange tube 201 slide relative to each other during the translation of the heat exchange tube 201, the contact between the second position regulating component 22 and the heat exchange tube 201 becomes smoother, reducing the frictional force between the second position regulating component 22 and the heat exchange tube 201, protecting the surface of the heat exchange tube 201, and being advantageous for enhancing the reliability of the heat exchange tube 201.

[0065] In some embodiments, as shown in FIG. 15, the processing device 100 for the heat exchanger further includes a second assembly 8, the second assembly 8 includes a plurality of spacing portions 81, the plurality of spacing portions 81 are installed at intervals along the length direction of the first component 121, the plurality of spacing portions 81 are installed at intervals along the width direction of the first component 121, at least two spacing portions are located on one side in the width direction of the first component 121, and at least two spacing portions are located on the other side in the width direction of the first component 121.

[0066] Specifically, as shown in FIG. 15, the plurality of spacing portions 81 can be evenly divided into two groups on average. One group of spacing portions 81 is provided at the left end of the first tube segment 2011, and the other group of spacing portions 81 is provided at the right end of the first tube segment 2011. Here, the spacing portion 81 is fixed in the front-rear direction and the spacing portion 81 is movable in the left-right direction.

[0067] During the translation of the heat exchange tube 201, a partial tube segment of the first tube segment 2011 translates backward. In this case, the first tube segment 2011 moves the second tube segment 2012 and the third tube segment 2013, and the first tube segment 2011 has a pulling force backward on the second tube segment 2012 and the third tube segment 2013. Thereby, the plurality of spacing portions 81 are provided at the left end and the right end of the first tube segment 2011, effectively preventing the second tube segment 2012 and the third tube segment 2013 from having a tendency to move backward, and reducing the deformation of the heat exchange tube 201.

[0068] In some embodiments, as shown in FIG. 16, there are a plurality of second platforms 12, and the widths of the second position restricting components 22 of the plurality of second platforms 12 are sequentially B1, B2, B3... Bn, and the widths of the second position restricting components 22 of the plurality of second platforms 12 are equal.

[0069] It should be noted that a plurality of second platforms 12 are provided between the first pipe segments 2011 of adjacent heat exchange pipes 201. The plurality of second platforms 12 are all movable in the front-rear direction, and the displacements of the plurality of second platforms 12 are different. Thereby, the processing device 100 for the heat exchanger according to the embodiment of the present application makes the force received by the heat exchange pipe 201 more uniform by translating the heat exchange pipe 201 collectively with the plurality of second platforms 12, the translation process is more stable, and the subsequent bending of the heat exchange pipe 201 becomes easier.

[0070] In some embodiments, as shown in FIG. 16, the width of one second position restricting component 22 of one second platform 12 is B1, the width of one second position restricting component 22 of another second platform 12 is B2, and the width of one second position restricting component 22 of another second platform 12 is Width Bn, and the total value of B1, B2 and Bn is smaller than 0.7A.

[0072] As shown in FIGS. 6 to 8, the processing method of the heat exchanger according to the embodiment of the present application includes the following steps.

[0073] A plurality of heat exchange tubes 201 are arranged at intervals along a first direction (for example, the front-rear direction shown in FIG. 6), and the plurality of heat exchange tubes 201 are position-regulated by a position regulating device 3 to regulate the movement of the plurality of heat exchange tubes 201 in the first direction.

[0074] Along the first direction, at least one first tube segment 2011 of a heat exchange tube 201 is moved a preset distance in the first direction relative to other parts of this heat exchange tube, so that the length direction (for example, the left-right direction shown in FIG. 6) of the partial tube segment of the first tube segment 2011 forms an angle with the length direction of other parts of this heat exchange tube, and the first tube segment 2011 is one or more.

[0075] As the first tube segment 2011 of the heat exchange tube 201 moves in the first direction, the second tube segment 2012 and the third tube segment 2013 of this heat exchange tube located on both sides of the first tube segment 2011 move oppositely in a second direction (for example, the left-right direction shown in FIG. 6).

[0076] In some embodiments, as shown in FIGS. 6 to 7, a plurality of heat exchange tubes 201 are arranged at intervals along the front-rear direction, and there are two position regulating devices 3. One position regulating device 3 is clamped on the tube segment of the left side part of the heat exchange tube 201, and the other position regulating device 3 is clamped on the tube segment of the right side part of the heat exchange tube 201. The tube segment between the two position regulating devices 3 is the first tube segment 2011 of the heat exchange tube 201.

[0077] Horizontally move the first tube segment 2011 of at least one heat exchange tube 201 in the front-rear direction, project the first tube segment 2011 in the front-rear direction with respect to other tube segments of the heat exchange tube 201, and when translating the first tube segment 2011, move the second tube segment 2012 and the third tube segment 13 of the heat exchange tube 201 in opposite directions, thereby reducing the concentration of the stress distribution on the heat exchange tube 201 and contributing to the improvement of reliability.

[0078] In some embodiments, as shown in FIG. 8, the method for processing the heat exchanger includes leveling the free-side end of the second tube segment 2012 in the first direction, leveling the free-side end of the third tube segment 2013 in the first direction, inserting the free-side end of the second tube segment 2012 into the first tube 41, and inserting the free-side end of the third tube segment 2013 into the second tube 42.

[0079] As shown in FIG. 8, the structures of the plurality of heat exchange tubes 201 are the same. By making the left ends of the plurality of heat exchange tubes 201 flush in the front-rear direction and also making the right ends of the plurality of heat exchange tubes 201 flush in the front-rear direction, when connecting the plurality of heat exchange tubes 201 to the first tube 41 and the second tube 42, the insertion depths of the heat exchange tubes 201 into the header are the same.

[0080] As shown in FIGS. 4 to 12, the method for processing the heat exchanger according to the embodiment of the present application includes the following steps.

[0081] In step 1, position-regulate the heat exchange tube 201 of a predetermined length in its thickness direction (for example, the front-rear direction shown in FIG. 9), and restrain or regulate the movement of the heat exchange tube 201 in the first direction (for example, the front-rear direction shown in FIG. 9).

[0082] In step 2, the first pipe segment 2011 of the heat exchange pipe 201 is moved along the first direction by a preset distance with respect to the first end (for example, the left end of the heat exchange pipe 201 in FIG. 9) and the second end (for example, the right end of the heat exchange pipe 201 in FIG. 9) in the length direction of the heat exchange pipe 201, so that a part of the length direction of the first pipe segment 2011 forms an angle with the length direction of other parts of the heat exchange pipe 201.

[0083] As the first pipe segment 2011 of the heat exchange pipe 201 moves in the first direction, the second pipe segment 2012 and the third pipe segment 2013 of the heat exchange pipe 201 located on both sides of the first pipe segment 2011 in the second direction (for example, the left-right direction shown in FIG. 9) move oppositely.

[0084] In step 3, a plurality of heat exchange pipes 201 of the same length after step 2 are installed at intervals along the first direction. The first ends in the length direction of the plurality of heat exchange pipes 201 are connected to the first pipe 41, the second ends in the length direction of the plurality of heat exchange pipes 201 are connected to the second pipe 42, and the first pipe segments 2011 of the plurality of heat exchange pipes 201 are flush with the length direction of the first pipe 41.

[0085] In some embodiments, as shown in FIGS. 6 to 12, a plurality of heat exchange pipes 201 are arranged at intervals along the front-rear direction. There are two position regulating devices 3. One position regulating device 3 is clamped by the pipe segment of the left side part of the heat exchange pipe 201, and the other position regulating device 3 is clamped by the pipe segment of the right side part of the heat exchange pipe 201. The partial pipe segment between the two position regulating devices 3 is the first pipe segment 2011 of the heat exchange pipe 201.

[0086] The first tube segment 2011 of the plurality of heat exchange tubes 201 is horizontally moved in the front-rear direction, the first tube segment 2011 is projected in the front-rear direction with respect to other tube segments of the heat exchange tube 201, and when the first tube segment 2011 is translated, the second tube segment 2012 and the third tube segment 13 of the heat exchange tube 201 are moved in opposite directions, thereby reducing the concentration of the stress distribution on the heat exchange tube 201 and contributing to the improvement of reliability. In some embodiments, as shown in FIG. 8, the method for processing the heat exchanger is a step of arranging the fins 5, arranging the fins 5 between the second tube segments 2012 of two adjacent heat exchange tubes 201 in the first direction, and arranging the fins 5 between the third tube segments 2013 of two adjacent heat exchange tubes 201 in the first direction.

[0087] In addition, in the method for processing the heat exchanger according to the embodiments of the present application, the fins 5 may be attached between the adjacent heat exchange tubes 201 after the heat exchange tubes 201 are moved, or the heat exchange tubes 201 may be translated after the fins 5 are attached between the adjacent heat exchange tubes 201.

[0088] As shown in FIGS. 6 to 8, in a specific embodiment of the present application, the heat exchange tubes 201 are moved and the fins 5 are attached between the adjacent heat exchange tubes 201.

[0089] In some embodiments, as shown in FIGS. 9 to 12, one position restricting device 3 is clamped to the left ends of the plurality of heat exchange tubes 201, the other position restricting device 3 is clamped to the right ends of the plurality of heat exchange tubes 201, fins 5 are provided between the second tube segments 2012 of the adjacent heat exchange tubes 201, fins 5 are provided between the third tube segments 2013 of the adjacent heat exchange tubes 201, and fins 5 are not provided between the first tube segments 2011 of the adjacent heat exchange tubes 201.

[0090] In some embodiments, the method for processing the heat exchanger includes restricting the displacement of the heat exchange tube 201 by the support device 6. There are two support devices 6. One support device 6 is provided at the left end of the first tube segment 2011, abuts against the first tube segment 2011, and this one support device 6 is adjacent to the fin 5. The other support device 6 is provided at the right end of the first tube segment 2011, abuts against the first tube segment 2011, and this other support device 6 is adjacent to the fin 5. When the first segment 2011 translates in the front-rear direction, the support device 6 is fixed in the front-rear direction, and the support device 6 can move freely in the left-right direction. Therefore, when the first tube segment 2011 moves, the fin area of the heat exchange tube 201 cannot be moved, and the fin area of the heat exchange tube 201 will not be deformed by the first tube segment 2011. The surface quality of the heat exchanger in the embodiments of the present application is improved, which is beneficial to the improvement of the heat exchange performance.

[0091] Furthermore, a plurality of support shafts are provided on the support device 6. The support shafts abut against the heat exchange tube 201, and the support shafts are rotatable in their axial directions. Thereby, the frictional force between the heat exchange tube 201 and the support shafts during the movement of the heat exchange tube 201 is reduced.

[0092] In some embodiments, as shown in FIGS. 11 to 12, when moving the first tube segment 2011 along the first direction, a plurality of partial tube segments of the first tube segment 2011 are moved, and the moving distances of each partial tube segment in the first direction are different such that the length direction of the partial tube segment of the first tube segment 2011 and the length direction of other parts of the heat exchange tube 201 form an angle.

[0093] It should be noted that in the present application, the first tube segment 2011 can be pushed collectively by a plurality of pressing devices 7. Here, the plurality of pressing devices 7 are arranged at intervals in the left-right direction. In the present application, for a single pressing device 7, by pushing the first tube segment 2011 with a plurality of pressing devices 7, the unit pressure of the force point applied to the first tube segment 2011 is reduced, the force received by the first tube segment 2011 is made more reasonable, and it is avoided that the pressure becomes excessive and damages the first tube segment 2011.

[0095] Note that by pushing the first tube segments 2011 of the heat exchange tube 201 by a preset distance so that the first tube segments 2011 in the bending region of the heat exchange tube 201 are spaced apart from each other, the heat exchange efficiency of the heat exchange tube 201 can be improved, the cleaning of the bending region of the heat exchange tube 201 is facilitated, and the service life of the heat exchange tube 201 can be effectively extended.

[0096] Preferably, the translated first tube segments 2011 may be U-shaped or V-shaped.

Preferably, the left position regulating device 3 can clamp the left end portion of the heat exchange tube 201, and the right position regulating device 3 can clamp the right end portion of the heat exchange tube 201.
