Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of flat tubes, and particularly to a manufacturing method of a flat tube assembly with joints. Background Art
[0002] Multiple flat tubes are connected in parallel through joints and are arranged in a heat exchanger. When the heated coolant enters the multiple flat tubes through the joints, the coolant transfers heat to the outside of the flat tubes through contact with the tube wall, thereby reducing the temperature of the coolant flowing through the flat tubes.
[0003] In the prior art, the connection with the joint is achieved by applying glue to the end of the flat tube. After long-term use, small pores will appear at the connection between the flat tube and the joint, resulting in leakage of the coolant. To strengthen the connection strength between the flat tube and the joint, the joint is welded to the end of the flat tube by welding. Since the flat tube is thin and prone to shrinkage at high temperatures, leakage of the coolant will also occur after the joint is welded to the end of the flat tube. Summary of the Invention

[0008] Welding fusion: Heat the two sealing sheaths to weld the second sealing portion to the first sealing portion, and weld the portion of the manifold joint member inserted into the insertion space to the inner wall of the insertion space, so as to connect the two manifold joint members to the two end portions of the pipe body member through the two sealing sheaths, thereby manufacturing a flat pipe assembly with joints.
[0009] According to an embodiment of the present invention, before the operation of sheath casting, the two end portions of the pipe body member are subjected to plasma treatment.
[0010] According to an embodiment of the present invention, the manifold joint member has an abutting step, and circumferentially extends at the end of the manifold joint member inserted into the insertion space to form the abutting step.
[0011] According to an embodiment of the present invention, the manifold joint member further has a plurality of joint support ribs, and the inner wall portions of the flow dividing space and the flow space of the manifold joint member extend away from the manifold joint member to form the joint support ribs.
[0012] According to an embodiment of the present invention, a plurality of partition plates are further formed in the pipe body member along the extending direction, and the plurality of partition plates are respectively located in the two connection channels and the flow channel.

[0014] According to an embodiment of the present invention, the method for manufacturing the flat pipe assembly with joints further includes the following steps:
[0015] Fabricate two pairs of plugging members, each of the plugging members having two plugging portions, the two plugging portions being respectively adapted to the channel ports of the connection channel separated by the partition plate and the channel ports of the flow channel separated by the partition plate. After fabricating the pipe member, arrange the two pairs of plugging members at the two end portions of the pipe member in a relative manner, and insert the two plugging portions of each plugging member into the channel ports of the connection channel and the flow channel respectively separated by the partition plate and close to the flow dividing plate. Furthermore, insert the plurality of removal support members of the two injection molding support members into the channel ports of the connection channel and the flow channel respectively separated by the partition plate and not inserted with the plugging portions. While keeping the removal support members in contact with the inner walls of the channel ports of the connection channel and the flow channel respectively separated by the partition plate and not inserted with the plugging portions, inject in a surrounding manner between the two end portions of the pipe member and the outer peripheries of the two injection molding support members respectively to form the sealing sheath.

That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of this element can be multiple. The term "a" should not be construed as limiting the quantity.
[0032] Refer to Figures 1 to 8, the manufacturing method of the flat tube assembly with joints according to a preferred embodiment of the present invention will be described in detail below, and the manufacturing method of the flat tube assembly with joints includes the following steps:
[0033] (1) Component manufacturing: Manufacture a tube body component 10 and two manifold joint components 20, and form two flow dividing plates 11 in the tube body component 10 along the extending direction to divide the tube body component 10 into two connection channels 101 and a flow turning channel 102 located between the two flow dividing plates 11. One end of each of the two flow dividing plates 11 has a first sealing portion 111, and the first sealing portions 111 of the two flow dividing plates 11 are respectively located at both ends of the tube body component 10. A flow dividing space 201 and a flow turning space 202 are formed in the manifold joint component 20, and a second sealing portion 21 is formed between the flow dividing space 201 and the flow turning space 202 in the manifold joint component 20. A liquid collecting space 203 for introducing coolant and a guiding channel 204 are further formed in the manifold joint component 20, and both ends of the guiding channel 204 are respectively communicated with the flow dividing space 201 and the liquid collecting space 203;
[0034] (2) Sheath casting: Insert a plurality of removable support members 31 of two injection molding support members 30 into both ends of the two connection channels 101 and both ends of the flow turning channel 102 respectively, and keep the removable support members 31 in contact with the inner walls of the connection channels 101 and the flow turning channel 102, and then inject in a surrounding manner between the two ends of the tube body component 10 and the outer circumferences of the two injection molding support members 30 respectively to form a sealing sheath 40;
[0035] (3) Inserting joints: Withdraw the plurality of removable support members 31 of the two injection molding support members 30 from the connection channels 101 and the flow turning channel 102 respectively, so as to form an insertion space 401 inside the end of the sealing sheath 40 away from the tube body component 10. At the same time, keep the two sealing sheaths 40 respectively connected to the outer circumferences of both ends of the tube body component 10, and insert the two manifold joint components 20 into the insertion space 401 in such a way that the second sealing portion 21 abuts against the first sealing portion 111, so that both ends of the two connection channels 101 are respectively communicated with the flow dividing space 201 of one of the manifold joint components 20 and the flow turning space 202 of the other manifold joint component 20, and both ends of the flow turning channel 102 are respectively communicated with the flow turning spaces 202 of the two manifold joint components 20;
[0036] (4)Welding fusion: Heat at the two sealing sheaths 40 to weld the second sealing portion 21 to the first sealing portion 111, and weld the portion of the current collector joint member 20 inserted into the insertion space 401 to the inner wall of the insertion space 401, so as to connect the two current collector joint members 20 to both ends of the pipe member 10 by the two sealing sheaths 40, thereby fabricating a flat pipe assembly with joints.
[0037] It is worth mentioning that when the sealing sheaths 40 are formed by injection molding in a surrounding manner on the outer circumferences between the two ends of the pipe member 10 and the two injection molding support members 30 respectively, since the plurality of removal support members 31 of the two injection molding support members 30 are respectively inserted into both ends of the two connection channels 101 and both ends of the flow channel 102, and the removal support members 31 are kept in contact with the inner walls of the connection channel 101 and the flow channel 102, the high temperature during injection molding will not cause heat shrinkage of the pipe member 10, thereby avoiding the collapse of the connection channel 101 and the flow channel 102 and resulting in pores in the pipe member 10, and preventing the coolant from flowing out through the pores.
[0038] Meanwhile, the setting of the sealing sheath 40 can seal the pores between the pipe member 10 and the current collector joint member 20, thereby enhancing the sealing performance of the connection between the pipe member 10 and the current collector joint member 20 through the sealing sheath 40 and preventing the coolant from leaking through the pores.
[0039] Among them, since the wall thickness of the pipe member 10 is relatively thin and it is easy to bend, the sealing sheath 40 is coated on the outer peripheral surface of the end of the pipe member 10 to support the end of the pipe member 10 through the sealing sheath 40, thereby reducing the probability of bending of the end of the pipe member 10. At the same time, compared with the way of directly connecting the end of the pipe member 10 to the current collector joint member 20, the strength of the overall connection between the pipe member 10 and the current collector joint member 20 can be enhanced through the sealing sheath 40.
[0040] When performing the welding fusion operation, since the sealing sheath 40 is coated on the outer peripheral surface of the end of the pipe member 10, through the coating of the sealing sheath 40, when heating at the two sealing sheaths 40, the outer wall of the end of the pipe member 10 can be pulled by the sealing sheath 40 to avoid heat shrinkage of the connection channel 101 and the flow channel 102.
[0041] It can be understood that the two current collector joint members 20 are respectively inserted into the insertion space 401 of the sealing sheath 40, and after being respectively connected to the two end portions of the pipe member 10 through the sealing sheath 40, the coolant in the liquid collection space 203 of one of the current collector joint members 20 will flow through the diversion channel 204 and the diversion space 201 of the current current collector joint member 20 in sequence, and after flowing into one of the connection channels 101, it will be guided by the flow-through space 202 of the other current collector joint member 20 to enter the flow-through channel 102 from one end of the flow-through channel 102, and flow back from the other end of the flow-through channel 102 into the flow-through space 202 of one of the current collector joint members 20, and after being guided by the flow-through space 202 of one of the current collector joint members 20, it will flow into the other connection channel 101, and after flowing through the diversion space 201 and the diversion channel 204 of the other current collector joint member 20 in sequence, it will enter the liquid collection space 203.
[0042] It is worth mentioning that compared with the method of directly passing the coolant from one end to the other end inside the pipe member 10, when the coolant flows in the flat pipe assembly with joints in this solution, since after the coolant enters one of the connection channels 101, it can flow back into the flow-through channel 102 under the guidance of one of the flow-through spaces 202, and flow to the other connection channel 101 under the guidance of the flow-through space 202 of the other current collector joint member 20, thereby increasing the contact time of the coolant with the inner wall of the connection channel 101 and the inner wall of the flow-through channel 102, and improving the total amount of heat transferred from the coolant to the outside of the pipe member 10 by heat transfer when the coolant flows in the pipe member 10 of the same volume. At the same time, since the cross-sectional size of the coolant decreases when it flows in the connection channel 101 and the flow-through channel 102, the total cost of the coolant can be reduced.
[0043] Preferably, before the operation of pouring the sheath, the two end portions of the pipe member 10 are subjected to plasma treatment.
[0044] As an example, after the two end portions of the pipe member 10 are subjected to plasma treatment, rough textures will be formed on the outer periphery of the two end portions of the pipe member 10 to increase the frictional force of contact between the pipe member 10 and the sealing sheath 40, thereby enhancing the connection stability between the pipe member 10 and the sealing sheath 40, preventing the sealing sheath 40 from slipping off the end portion of the pipe member 10, so as to avoid generating a gap between the pipe member 10 and the sealing sheath 40.
[0045] Meanwhile, after the two ends of the pipe body member 10 are subjected to plasma treatment, rough textures will be formed on the surfaces of the two ends of the pipe body member 10 at the contact positions with the two current collecting joint members 20 respectively, so as to increase the frictional force at the contact between the pipe body member 10 and the current collecting joint members 20, thereby enhancing the stability of the connection between the pipe body member 10 and the current collecting joint members 20.
[0046] Preferably, the current collecting joint member 20 has an abutting step 22. The end of the current collecting joint member 20 inserted into the insertion space 401 extends circumferentially to form the abutting step 22, so that when the current collecting joint member 20 is inserted into the insertion space 401, the insertion depth of the current collecting joint member 20 is limited by the abutting step 22 against the surface of the sealing sheath 40, preventing the pipe body member 10 from being pushed by the current collecting joint member 20 and separated from the sealing sheath 40.
[0047] The current collecting joint member 20 further has a plurality of joint support ribs 23, and the inner wall parts of the flow dividing space 201 and the flow turning space 202 of the current collecting joint member 20 extend away from the current collecting joint member 20 to form the joint support ribs 23.
[0048] It is worth mentioning that during the process of heating the sealing sheath 40 and partially welding the current collecting joint member 20 to the inner wall of the insertion space 401, since the current collecting joint member 20 has a plurality of joint support ribs 23 located on the inner wall of the flow dividing space 201 and inside the flow turning space 202, the formation of the flow dividing space 201 and the flow turning space 202 is strengthened by the joint support ribs 23, preventing the flow dividing space 201 and the flow turning space 202 from shrinking due to heating of the current collecting joint member 20.
[0049] Preferably, the pipe body member 10, the current collecting joint member 20, and the sealing sheath 40 are all made of resin.
[0050] Preferably, the injection molding support member 30 is made of metal. After the sealing sheath 40 is injection molded around the outer circumferences between the two ends of the pipe body member 10 and the two injection molding support members 30 respectively, since the injection molding support member 30 is made of metal, adhesion between the sealing sheath 40 and the injection molding support member 30 can be prevented, thereby facilitating the removal of the plurality of dismounting support members 31 of the injection molding support member 30 from the connection channel 101 and the flow turning channel 102.
[0051] Preferably, a plurality of partition plates 12 are further formed in the tube body member 10 along the extending direction. The plurality of partition plates 12 are respectively located in the two connection channels 101 and the flow channel 102 to separate the connection channels 101 and the flow channel 102 through the partition plates 12 and reinforce the connection channels 101 and the flow channel 102 through the partition plates 12.
[0052] It is worth mentioning that after the coolant enters the connection channels 101 and the flow channel 102, the coolant can increase the total amount of heat transferred to the tube body member 10 per unit time by contacting the plurality of partition plates 12, thereby better cooling the coolant.
[0053] In this embodiment, further, the manufacturing method of the flat tube assembly with connectors further includes the following steps:
[0054] Manufacture two pairs of plugging members 50. Each plugging member 50 has two plugging parts 51. The two plugging parts 51 are respectively adapted to the channel ports of the connection channel 101 separated by the partition plate 12 and the channel ports of the flow channel 102 separated by the partition plate 12. After the tube body member 10 is manufactured, the two pairs of plugging members 50 are respectively arranged at the two end parts of the tube body member 10 in a relative manner, and the two plugging parts 51 of each plugging member 50 are respectively inserted into the channel ports of the connection channel 101 and the flow channel 102 separated by the partition plate 12 and close to the flow dividing plate 11. Then, the plurality of removable support members 31 of the two injection molding support members 30 can be respectively inserted into the channel ports of the two connection channels 101 and the flow channel 102 separated by the partition plate 12 and not inserted with the plugging parts 51, and the removable support members 31 are kept in contact with the inner walls of the channel ports of the connection channel 101 and the flow channel 102 separated by the partition plate 12 and not inserted with the plugging parts 51, so as to inject in a surrounding manner between the two end parts of the tube body member 10 and the outer peripheries of the two injection molding support members 30 respectively to form the sealing sheath 40.
[0055] That is to say, after the tube body member 10 is manufactured, the two pairs of plugging members 50 are respectively arranged at the two end parts of the tube body member 10 in a relative manner, and the two plugging parts 51 of each plugging member 50 are respectively inserted into the channel ports of the connection channel 101 and the flow channel 102 separated by the partition plate 12 and close to the flow dividing plate 11, and then the operation of sheath pouring is carried out.
[0056] Wherein, after the two plugging parts 51 of the plugging member 50 are respectively inserted into the channel ports of the connection channel 101 and the flow channel 102 that are separated by the partition plate 12 and close to the flow dividing plate 11, the two plugging parts 51 of the plugging member 50 will plug the channel ports of the connection channel 101 and the flow channel 102 that are separated by the partition plate 12 and close to the flow dividing plate 11. Furthermore, the total amount of coolant flowing into the pipe member 10 can be reduced. Also, according to customer requirements, the two plugging parts 51 of the plugging member 50 can be used to plug the corresponding channel ports of the connection channel 101 and the flow channel 102 that are separated by the partition plate 12, so as to achieve the purpose of adjusting the total amount of coolant flowing into the pipe member 10.
[0057] In another variant embodiment, the manufacturing method of the flat tube assembly with connectors further comprises the following steps:
[0058] Manufacture two pairs of plugging members 50. Each plugging member 50 has two plugging parts 51, and the two plugging parts 51 are respectively adapted to the channel ports of the connection channel 101 separated by the partition plate 12 and the channel ports of the flow channel 102 separated by the partition plate 12. After the plurality of removable support members 31 of the two injection molding support members 30 are respectively withdrawn from the connection channel 101 and the flow channel 102, and after the insertion space 401 is formed inside the end of the sealing sheath 40 away from the pipe member 10, the two pairs of plugging members 50 are respectively arranged at both ends of the pipe member 10 in an opposite manner, and the two plugging parts 51 of each plugging member 50 are respectively inserted into the channel ports of the connection channel 101 and the flow channel 102 that are separated by the partition plate 12 and close to the flow dividing plate 11. Furthermore, the two manifold joint members 20 can be inserted into the insertion space 401.
[0059] Wherein, after the two plugging parts 51 of the plugging member 50 are respectively inserted into the channel ports of the connection channel 101 and the flow channel 102 that are separated by the partition plate 12 and close to the flow dividing plate 11, the total amount of coolant flowing into the pipe member 10 can be reduced. At the same time, according to customer requirements, the two plugging parts 51 of the plugging member 50 can be used to plug the corresponding channel ports of the connection channel 101 and the flow channel 102 that are separated by the partition plate 12, so as to achieve the purpose of adjusting the total amount of coolant flowing into the pipe member 10.
[0060] In yet another variant embodiment, further, the manufacturing method of the flat tube assembly with connectors further comprises the following steps:
[0061] When a plurality of the removal support members 31 of the two injection molding support members 30 are respectively inserted into the two connection channels 101 and the flow channel 102, and the channel ports are respectively separated by the partition plate 12, the removal support members 31 of the injection molding support members 30 corresponding to the channel ports of the connection channels 101 and the flow channel 102 that are respectively separated by the partition plate 12 and are close to the flow dividing plate 11 are removed, so that a gap is generated between the injection molding support member 30 where the removal support member 31 is removed and the pipe body member 10. When the sealing sheaths 40 are respectively injection molded in a surrounding manner between the two end portions of the pipe body member 10 and the outer peripheries of the two injection molding support members 30, the injection molding material flows into the channel ports of the connection channels 101 and the flow channel 102 that are respectively separated by the partition plate 12 and are close to the flow dividing plate 11 from the gap between the injection molding support member 30 and the end portion of the pipe body member 10, and then a blocking member 50 integrally formed with the sealing sheath 40 is formed at the channel ports of the connection channels 101 and the flow channel 102 that are respectively separated by the partition plate 12 and are close to the flow dividing plate 11.
[0062] It is worth mentioning that the blocking member 50 is used to block the channel ports of the connection channels 101 and the flow channel 102 that are respectively separated by the partition plate 12 and are close to the flow dividing plate 11, thereby reducing the total amount of coolant flowing into the pipe body member 10.
[0063] To enable those skilled in the art to understand the present invention, in at least one embodiment of the present invention, only two pairs of the blocking members 50 are fabricated. Each of the blocking members 50 has two blocking portions 51, and the two blocking portions 51 are respectively adapted to the channel ports of the connection channel 101 separated by the partition plate 12 and the channel ports of the flow channel 102 separated by the partition plate 12. After the pipe body member 10 is fabricated, the two pairs of the blocking members 50 are respectively arranged at the two end portions of the pipe body member 10 in a relative manner, and the two blocking portions 51 of each of the blocking members 50 are respectively inserted into the channel ports of the connection channel 101 and the flow channel 102 that are respectively separated by the partition plate 12 and are close to the flow dividing plate 11 as an example for illustration.
[0064] It is worth mentioning that when the two plugging parts 51 of each plugging member 50 are respectively inserted into the channel ports of the connection channel 101 and the flow channel 102 that are separated by the partition plate 12 and close to the flow dividing plate 11, and the plugging member 50 is partially located at the end in the extending direction of the flow dividing plate 11, when the manifold joint member 20 is inserted into the insertion space 401, the second sealing part 21 of the manifold joint member 20 will indirectly abut against the first sealing part 111 through the plugging member 50. Under the action of the plugging member 50, it is possible to avoid the situation that the second sealing part 21 of the manifold joint member 20 is offset due to manufacturing errors, and thus cannot abut against the first sealing part 111 when the manifold joint member 20 is inserted into the insertion space 401. Furthermore, it is possible to avoid the coolant from flowing into the gap between the first sealing part 111 and the second sealing part 21.
[0065] That is to say, after the manifold joint member 20 is inserted into the insertion space 401, the plugging member 50 will be partially located between the first sealing part 111 and the second sealing part 21.
[0066] In this embodiment, as deformable, glue is injected into the channel ports of the connection channel 101 and the flow channel 102 that are separated by the partition plate 12 and close to the flow dividing plate 11 to form the plugging parts 51 of the plugging member 50.
[0067] Preferably, each of the removal support members 31 of the injection molding support member 30 is detachable. After the two plugging parts 51 of the plugging member 50 are respectively inserted into the channel ports of the connection channel 101 and the flow channel 102 that are separated by the partition plate 12 and close to the flow dividing plate 11, the corresponding removal support member 31 is disassembled, so that the disassembled removal support members 31 can be respectively smoothly inserted into the channel ports of the two connection channels 101 and the flow channel 102 that are separated by the partition plate 12 and not inserted with the plugging parts 51, and then subsequent operations can be carried out.
[0068] Preferably, during the process that the manifold joint member 20 is inserted into the insertion space 401 and the second sealing part 21 abuts against the first sealing part 111 through the plugging member 50, a part of the plugging member 50 will be pressed by the manifold joint member 20 against the end of the pipe member 10, thereby stabilizing the position and posture of the plugging member 50 through the manifold joint member 20 and preventing the two plugging parts 51 of the plugging member 50 from falling off the channel ports of the connection channel 101 and the flow channel 102 that are separated by the partition plate 12 and close to the flow dividing plate 11 respectively.
[0069] Those skilled in the art can understand that when heat is applied to the two sealing sheaths 40, the portions of the first sealing portion 111, the second sealing portion 21, and the plugging member 50 located in the extending direction of the flow dividing plate 11 will be welded together to prevent pores from being generated between the plugging member 50 and the first sealing portion 111 and between the plugging member 50 and the second sealing portion 21; the manifold joint member 20 will be welded to the inner wall of the insertion space 401 to prevent pores from being generated between the manifold joint member 20 and the inner wall of the insertion space 401; the abutting step 22 will be welded to the sealing sheath 40 to enhance the integrity between the manifold joint member 20 and the sealing sheath 40; the portion of the plugging member 50 pressed by the manifold joint member 20 against the end of the tube member 10 will be welded to the tube member 10 and the manifold joint member 20 together to further enhance the integrity of the tube member 10, the manifold joint member 20, the sealing sheath 40, and the plugging member 50 while fixing the position and posture of the plugging member 50.
[0070] Preferably, during the heating process at the two sealing sheaths 40, the tube member 10 and the manifold joint member 20 are continuously pushed towards each other and squeezed to improve the welding tightness between the tube member 10, the manifold joint member 20, and the plugging member 50, and at the same time improve the welding tightness between the abutting step 22 of the manifold joint member 20 and the sealing sheath 40.
[0071] Preferably, the width of the second sealing portion 21 in the extending direction of the tube member 10 is greater than the width of the first sealing portion 111 of the flow dividing plate 11 in the extending direction of the tube member 10, so as to reduce the influence of errors on the successful abutment of the second sealing portion 21 against the first sealing portion 111 through the plugging member 50 when the second sealing portion 21 of the manifold joint member 20 has an offset during manufacturing.

The advantages of the present invention have been fully and effectively realized.
