[0002] Multiple pipelines are connected in parallel through joints and are arranged in a heat exchanger, the cooling liquid after being heated enters the pipeline through the joint, and the cooling liquid transmits heat to the outside of the pipeline through contact with the pipe wall, thereby reducing the temperature of the cooling liquid flowing through the pipeline.
[0003] In order to increase the contact area of the cooling liquid and the pipe wall, multiple multi -pass flat pipes are connected in parallel through joints and arranged in a heat exchanger, so that the cooling liquid in the multi -pass flat pipe can transmit more heat to the outside of the pipeline in the same unit time through contact with the pipe wall, thereby improving the cooling speed of the cooling liquid.
[0004] Since the amount of heat transmitted by the cooling liquid is proportional to the contact time of the cooling liquid and the pipe wall, the existing multi -pass flat pipe is connected in parallel through the joint, and the length of the multi -pass flat pipe is lengthened or the number of multi -pass flat pipes connected in parallel through the joint is increased to increase the heat transmitted by the cooling liquid through the pipe wall of the multi -pass flat pipe. Such practice will result in an increase in the space occupied by the multi -pass flat pipe connected in parallel through the joint, and will result in an increase in the time required for the installation of the multi -pass flat pipe connected in parallel through the joint, and will result in an increase in the amount of cooling liquid, which is not conducive to controlling the cost of the amount of cooling liquid.

[0026] Reference Figures 1 to 5 A multi-channel flat tube assembly according to a preferred embodiment of the present application will be described in detail below, wherein the multi-channel flat tube assembly comprises a tube member 10, two manifold members 20 and two sealing sheaths 30.
[0027] Specifically, the tube member 10 comprises a flat tube body 11 and at least two flow dividing pieces 12. The at least two flow dividing pieces 12 are arranged in the flat tube body 11 in a manner consistent with the extension direction of the flat tube body 11, so as to divide the internal space of the flat tube body 11 into two connection channels 1101 and at least one flow transfer channel 1102 through the flow dividing pieces 12. The two connection channels 1101 are formed on both sides in the extension direction of the flat tube body 11. The flow transfer channel 1102 is formed between adjacent flow dividing pieces 12. The two flow dividing pieces 12 respectively form a first sealing portion 121 at different ends in the extension direction. The first sealing portions 121 of the two flow dividing pieces 12 are respectively located at the two ends of the flat tube body 11.
[0028] The current collector member 20 includes a current collecting portion 21, a pipe connecting portion 22, and a second sealing portion 23. The current collecting portion 21 is connected to the pipe connecting portion 22. The current collecting portion 21 forms a current collecting space 2101 and a flow guiding passage 2102, one end of the flow guiding passage 2102 being in communication with the current collecting space 2101. The pipe connecting portion 22 forms a flow dividing space 2201 and a flow transferring space 2202. The second sealing portion 23 is fixed to the pipe connecting portion 22, and the second sealing portion 23 is located between the flow dividing space 2201 and the flow transferring space 2202 to separate the flow dividing space 2201 and the flow transferring space 2202 by the second sealing portion 23. The other end of the flow guiding passage 2102 is in communication with the flow dividing space 2201. The flow dividing space 2201 and the flow transferring space 2202 are both formed at the end of the pipe connecting portion 22 away from the current collecting portion 21. The pipe connecting portion 22 of each of the two current collector members 20 corresponds to one end of the flat tube body 11, and the second sealing portion 23 of each of the two current collector members 20 abuts against the first sealing portion 121 at the end of the flat tube body 11. That is, when the pipe connecting portion 22 of each of the two current collector members 20 corresponds to one end of the flat tube body 11, the flow dividing space 2201 of the pipe connecting portion 22 of one of the current collector members 20 faces the flow transferring space 2202 of the pipe connecting portion 22 of the other current collector member 20, and the flow dividing space 2201 of each of the two pipe connecting portions 22 is in communication with one end of the connection passage 1101, and the flow transferring passage 1102 is in communication with the other end of the connection passage 1101 through the flow transferring space 2202 of each of the two pipe connecting portions 22.
[0029] The two sealing sheaths 30 are arranged in a surrounding manner between the two ends of the flat tube body 11 and the two pipe connecting portions 22 to enhance the connection between the pipe connecting portion 22 and the end of the flat tube body 11 by the sealing sheath 30, and to enhance the sealing of the connection between the pipe connecting portion 22 and the flat tube body 11 by the sealing sheath 30.
[0030] As an example, the pipe sections 22 of the two manifold members 20 correspond to the two ends of the flat tube body 11 respectively, and when the second abutting sealing sections 23 of the two manifold members 20 abut against the first abutting sealing sections 121 at the two ends of the flat tube body 11 respectively, the cooling liquid in the liquid collecting space 2101 of the liquid collecting section 21 of one of the manifold members 20 will flow through the flow guiding passage 2102 of the liquid collecting section 21 of the one manifold member 20 and the flow dividing space 2201 of the pipe section 22 of the one manifold member 20 in sequence, and after flowing into the one connecting passage 1101, the cooling liquid will be guided into the flow transferring passage 1102 through the flow transferring space 2202 of the pipe section 22 of the other manifold member 20, so as to flow into the other connecting passage 1101 after flowing from the flow transferring passage 1102 to the flow transferring space 2202 of the pipe section 22 of the one manifold member 20, and then flow into the liquid collecting space 2101 of the other manifold member 20 after flowing through the flow dividing space 2201 of the other manifold member 20 and the flow guiding passage 2102 of the other manifold member 20 in sequence.
[0031] It is worth mentioning that, compared with the way of directly passing the cooling liquid from one end to the other end inside the flat tube body 11, such a way can increase the distance of the cooling liquid flowing in the flat tube body 11, thereby increasing the time of the cooling liquid contacting the inner wall of the connecting passage 1101 and the inner wall of the flow transferring passage 1102, and improving the total amount of heat transferred from the flat tube body 11 to the outside of the flat tube body 11 by the cooling liquid flowing in the same space through heat transfer. At the same time, since the cross-sectional size of the cooling liquid is reduced when flowing in the connecting passage 1101 and the flow transferring passage 1102, the total cost of the cooling liquid can be reduced.
[0032] As can be understood by those skilled in the art, after the heat of the cooling liquid is transferred to the flat tube body 11, the heat of the flat tube body 11 can be absorbed by cooling the surface of the flat tube body 11, thereby continuously reducing the temperature of the cooling liquid. Therefore, the thinner the wall thickness of the flat tube body 11 is, the more significant the cooling effect will be. When the thin flat tube body 11 is connected with the pipe section 22 of the manifold member 20, the strength of the connection between the flat tube body 11 and the pipe section 22 can be improved by the sealing sheath 30, thereby avoiding the bending of the flat tube body 11 at the connection with the pipe section 22.
[0033] Meanwhile, since the wall of the flat tube body 11 is thin, the contact points between the flat tube body 11 and the connecting tube part 22 are less when they are connected, and tiny pores are easily generated between the flat tube body 11 and the connecting tube part 22, causing the cooling liquid to seep out of the tiny pores. Since the sealing sheath 30 is arranged between the flat tube body 11 and the connecting tube part 22, the tiny pores generated between the flat tube body 11 and the connecting tube part 22 can be closed by the sealing sheath 30, thereby preventing the cooling liquid from seeping out.
[0034] Preferably, the tube body member 10 further comprises a plurality of partition pieces 13. The plurality of partition pieces 13 are fixed to the flat tube body 11 in a direction consistent with the flow dividing piece 12, and the plurality of partition pieces 13 are respectively arranged in the two connecting channels 1101 and the flow transferring channel 1102, so as to separate the space of the connecting channels 1101 and the flow transferring channel 1102 by the partition pieces 13, and reinforce the connecting channels 1101 and the flow transferring channel 1102 by the partition pieces 13.
[0035] It is worth mentioning that after the cooling liquid enters the connecting channels 1101 and the flow transferring channel 1102 and contacts the surface of the partition pieces 13, the cooling liquid can indirectly transfer heat to the flat tube body 11 by contacting the partition pieces 13, thereby improving the cooling speed of the cooling liquid in the connecting channels 1101 and the flow transferring channel 1102.
[0036] Preferably, the tube body member 10 and the manifold member 20 are both made of resin.
[0037] Preferably, the sealing sheath 30 forms a closed channel 301. The two ends of the flat tube body 11 are respectively inserted into one end of the closed channel 301 of the two sealing sheaths 30, and the two ends of the flat tube body 11 are respectively attached to the inner walls of the closed channel 301 of the two sealing sheaths 30. The ends of the connecting tube parts 22 of the two manifold members 20 away from the collecting liquid parts 21 are respectively inserted into the other end of the closed channel 301 of the two sealing sheaths 30, and the ends of the connecting tube parts 22 of the two manifold members 20 away from the collecting liquid parts 21 are respectively attached to the inner walls of the closed channel 301 of the two sealing sheaths 30. In other words, the ends of the connecting tube parts 22 of the two manifold members 20 away from the collecting liquid parts 21 are respectively inserted into the closed channel 301 of the sealing sheaths 30 in a manner corresponding to the two ends of the flat tube body 11, and the ends of the connecting tube parts 22 of the two manifold members 20 away from the collecting liquid parts 21 and the two ends of the flat tube body 11 are respectively attached to the inner walls of the closed channel 301.
[0038] Thus, the connection between the pipe connection portion 22 and the end portion of the flat tube body 11 is reinforced by the two sealing sheaths 30, and the sealing between the pipe connection portion 22 and the flat tube body 11 is also reinforced by the sealing sheaths 30.
[0039] Preferably, the end portion of the pipe connection portion 22 of each of the two manifold members 20 away from the header portion 21 extends along a circumferential direction perpendicular to the extending direction of the pipe connection portion 22 to form an abutting step 221. When the end portion of the pipe connection portion 22 away from the header portion 21 is inserted into the closed channel 301, the abutting step 221 of the pipe connection portion 22 abuts against the sealing sheath 30, thereby limiting the insertion depth of the pipe connection portion 22 into the closed channel 301, so as to prevent the pipe connection portion 22 from being excessively inserted into the closed channel 301 and hindering the insertion of the flat tube body 11 into the closed channel 301.
[0040] Specifically, the manifold member 20 further comprises a plurality of joint support ribs 24. The plurality of joint support ribs 24 are arranged on the pipe connection portion 22, and each of the plurality of joint support ribs 24 is arranged on the inner wall of the flow distribution space 2201 and the flow conversion space 2202, so as to reinforce the pipe connection portion 22 to form the flow distribution space 2201 and the flow conversion space 2202.
[0041] As an example, in order to reinforce the connection between the pipe connection portion 22, the flat tube body 11 and the sealing sheath 30, the end portion of the pipe connection portion 22 away from the header portion 21 is inserted into the closed channel 301 of the sealing sheath 30 in a manner corresponding to the two end portions of the flat tube body 11, and the end portion of the pipe connection portion 22 away from the header portion 21 and the two end portions of the flat tube body 11 are respectively attached to the inner wall of the closed channel 301. Then, high temperature is applied to the sealing sheath 30, so as to melt the end portion of the pipe connection portion 22 in the closed channel 301 and the end portion of the flat tube body 11 in the closed channel 301 to the inner wall of the closed channel 301, so as to prevent the cooling liquid from flowing out from the gap between the flat tube body 11 and the sealing sheath 30, and prevent the cooling liquid from flowing out from the gap between the pipe connection portion 22 and the sealing sheath 30. At the same time, the first abutting sealing portion 121 and the second abutting sealing portion 23 abut against each other are also melted together, so as to prevent the cooling liquid from flowing through the gap between the first abutting sealing portion 121 and the second abutting sealing portion 23.
[0042] Further, the flat tube body 11 and the connecting tube portion 22 can be continuously pushed towards each other to be pressed during the process of applying high temperature to the sealing sheath 30, so as to improve the stability of the end of the connecting tube portion 22 in the closed passage 301 and the end of the flat tube body 11 in the closed passage 301 being respectively fused to the inner wall of the closed passage 301. Similarly, the stability of the connection between the first abutting sealing portion 121 and the second abutting sealing portion 23 being abutted and fused together can be improved. Meanwhile, the abutting step 221 abutting against the sealing sheath 30 can also be fused to the sealing sheath 30 under high temperature.
[0043] It can be understood that the smaller the space of the connecting passage 1101 and the flow transferring passage 1102, the smaller the total amount of cooling liquid in the flat tube body 11, so that the glue can be injected into the space of the connecting passage 1101 and the flow transferring passage 1102 separated by the partition 13 from both ends of the flat tube body 11, so as to reduce the total amount of cooling liquid entering the connecting passage 1101 and the flow transferring passage 1102. Meanwhile, since the total path distance of the cooling liquid flowing in the connecting passage 1101, the flow transferring passage 1102, the flow separating space 2201 and the flow transferring space 2202 is unchanged, the total amount of cooling liquid needed to be injected into the flat tube body 11 can be controlled to adapt to different use requirements of users.
[0044] Preferably, the multi-pass flat tube assembly further comprises at least two pairs of sealing members 40.
[0045] In the embodiment, the sealing member 40 comprises at least two sealing portions 41 and a mounting portion 42. One end of each of the two sealing portions 41 is fixedly connected to the mounting portion 42. The other end of each of the two sealing portions 41 is inserted into the passage port of the connecting passage 1101 and the flow transferring passage 1102 respectively separated by the partition 13 and close to the flow separating member 12. The mounting portions 42 of the two pairs of sealing members 40 are respectively arranged at the two ends of the flat tube body 11 in opposite ways.
[0046] The mounting portion 42 of two of the occlusion members 40 near the first occlusion portion 121 is arranged between the second occlusion portion 23 and the first occlusion portion 121, so that when the flat tube body 11 and the connector portion 22 are inserted into the sealing sheath 30 and the second occlusion portion 23 moves toward the first occlusion portion 121, the second occlusion portion 23 abuts against the mounting portion 42, and the mounting portion 42 abuts against the first occlusion portion 121, thereby fixing the position of the occlusion members 40 and preventing the two occlusion portions 41 of the occlusion members 40 from being separated from the connection channel 1101 and the flow switching channel 1102 respectively and from the port near the flow divider 12.
[0047] The occlusion members 40 are made of resin.
[0048] In another embodiment, the occlusion members 40 include an occlusion portion 41 and a mounting portion 42. One end of the occlusion portion 41 is fixedly connected to the mounting portion 42. Two pairs of mounting portions 42 of the occlusion members 40 are arranged at opposite ends of the flat tube body 11, and the other end of the occlusion portion 41 of the two pairs of occlusion members 40 is inserted into the channel port separated by the partition 13 and near the flow divider 12 of the connection channel 1101. Alternatively, the other end of the occlusion portion 41 of the two pairs of occlusion members 40 is inserted into the channel port separated by the partition 13 and near the flow divider 12 of the flow switching channel 1102.
[0049] Preferably, in the thickness direction of the flat tube body 11, the size of the mounting portion 42 is greater than the size in the thickness direction of the flat tube body 11, and the mounting portion 42 is partially located between the connector portion 22 and the end of the flat tube body 11, so that the mounting portion 42 is pressed against the end of the flat tube body 11 by the connector portion 22, thereby preventing the two occlusion portions 41 of the occlusion members 40 from being separated from the connection channel 1101 and the flow switching channel 1102 respectively and from the port near the flow divider 12.
[0050] Preferably, in the thickness direction of the flat tube body 11, the mounting portion 42 is partially attached to the sealing sheath 30.
[0051] As an example, during the process of applying high temperature at the sealing sheath 30, the mounting portion 42 can be welded to the inner wall of the connection passage 1101 and the flow transfer passage 1102 after being separated by the partition 13 and close to the port of the flow divider 12, so as to prevent the mounting portion 42 from being separated. At the same time, the mounting portion 42 can be welded to the flow divider 12, the connecting pipe portion 22 and the sealing sheath 30 due to high temperature, so as to improve the integrity between the sealing member 40, the flow divider 12, the flat pipe body 11 and the connecting pipe portion 22 and the sealing sheath 30. In this way, the mounting portion 42 between the first sealing portion 121 and the second sealing portion 23 can be welded to the first sealing portion 121 and the second sealing portion 23, so as to avoid the existence of gaps between the first sealing portion 121 and the mounting portion 42 and between the mounting portion 42 and the second sealing portion 23.
[0052] Preferably, the closed passage 301 of the sealing sheath 30 extends inwardly to form a reinforcing portion 31 close to one end of the flat pipe body 11, and a fitting wall 311 is formed on the side of the reinforcing portion 31 away from the flat pipe body 11. The fitting wall 311 is used to fit the edge of the mounting portion 42 in the extension direction of the flat pipe body 11. In this way, when the end of the flat pipe body 11 is inserted into the closed passage 301, the flat pipe body 11 is fitted to the reinforcing portion 31, and the mounting portion 42 is partially fitted to the sealing sheath 30 in the thickness direction of the flat pipe body 11, and the mounting portion 42 is partially fitted to the sealing sheath 30 in the extension direction of the flat pipe body 11.
[0053] It is worth mentioning that, due to the fact that the mounting portion 42 is partially fitted to the sealing sheath 30 in the thickness direction of the flat pipe body 11, and the mounting portion 42 is partially fitted to the sealing sheath 30 in the extension direction of the flat pipe body 11, the welding between the mounting portion 42 and the sealing sheath 30 can be more closely during the process of applying high temperature at the sealing sheath 30.
[0054] Preferably, the width of the second sealing portion 23 in the extension direction of the flat pipe body 11 is greater than the width of the first sealing portion 121 of the flow divider 12 in the extension direction of the flat pipe body 11.
[0055] It should be understood by those skilled in the art that the above description and the embodiments of the present application shown in the drawings are only examples and do not limit the present application. The advantages of the present application have been fully and effectively realized. The functions and structural principles of the present application have been shown and described in the embodiments, and the embodiments of the present application can be modified or changed without departing from the principles.
