Description

Technical Field

[0001] This application relates to the field of heat exchanger technology, and in particular to an integrated heat exchanger and thermal management system. Background Technology

[0002] Integrated heat exchangers typically involve the heat exchange of two fluid media. They include an inlet manifold, an outlet manifold, and a heat exchange tube section. External connecting pipes connect the inlet manifold and the outlet manifold, respectively, so that the heat exchange medium enters the heat exchange tube section through the inlet manifold via the external pipe at the inlet end, then enters the outlet manifold from multiple heat exchange tube sections, and flows into the external pipe at the outlet end.

[0003] Furthermore, to facilitate better heat exchange between the two heat exchange media, the heat exchange tubes flowing through them are typically assembled in a nested manner. Correspondingly, the inlet and outlet manifolds for the two heat exchange media are also assembled in a nested manner. These nested manifolds are defined as inner and outer tubes, respectively. To achieve communication between the inner and outer tubes, the outer tube is usually placed at the end of the inner tube. However, the outer tube cannot directly connect to the heat exchange tubes; that is, heat exchange tubes cannot be installed between the outer tubes. Therefore, given a fixed total length of the integrated heat exchanger along the inner tube direction, this arrangement significantly reduces the number of heat exchange tubes that can be assembled in the integrated heat exchanger. Summary of the Invention

[0004] Therefore, it is necessary to provide an integrated heat exchanger and thermal management system to solve the problem that the number of heat exchange tubes that can be installed in the integrated heat exchange device is greatly reduced due to the external pipelines being located at the ends of the internal pipes.

[0005] The integrated heat exchanger provided in this application includes a manifold assembly and a heat exchange tube assembly. The manifold assembly includes a first manifold, a second manifold, a third manifold, and a fourth manifold. The heat exchange tube assembly includes a first heat exchange tube and a second heat exchange tube. The third and fourth manifolds are arranged parallel to each other and spaced apart. The length direction of either the third or fourth manifold is defined as a first preset direction. Multiple second heat exchange tubes are arranged along the first preset direction, and both ends of the multiple second heat exchange tubes are respectively connected to the third and fourth manifolds. The first manifold is located on the side of the third manifold away from the second heat exchange tube and extends along the first preset direction. The second manifold is located on the side of the fourth manifold away from the second heat exchange tube and extends along the first preset direction. The first and second heat exchange tubes are arranged in a one-to-one correspondence. The first heat exchange tube is inserted into the second heat exchange tube, and one end of the first heat exchange tube passes through the opposite sidewall of the third manifold and connects to the first manifold. The other end of the first heat exchange tube passes through the opposite sidewall of the fourth manifold and connects to the second manifold. The two ends of the integrated heat exchanger along a first preset direction are defined as the first end and the second end, respectively. The external piping assembly is located between the first end and the second end and is connected to the corresponding manifold assembly.

[0006] In one embodiment, the first heat exchange tube is provided with a first heat exchange channel, and the first heat exchange channel is provided with a plurality of first partition strips that are equally spaced and extend along the length of the first heat exchange channel, so as to divide the first heat exchange channel into a plurality of parallel and non-communicating first branch channels, and the plurality of first branch channels are respectively connected to the first manifold and the second manifold.

[0007] In one embodiment, the outer wall of the first heat exchange tube and the inner wall of the second heat exchange tube are spaced apart to form a second heat exchange channel. The second heat exchange channel is provided with a plurality of second partition strips extending along the length of the second heat exchange channel to divide the second heat exchange channel into a plurality of parallel and non-communicating second branch channels. The plurality of second branch channels are respectively connected to the third manifold and the fourth manifold.

[0008] In one embodiment, a first baffle is provided inside the first manifold to divide the first manifold into an inlet section and an outlet section. The external piping assembly includes a first external pipe and a second external pipe. The first external pipe is connected to the inlet section, and the second external pipe is connected to the outlet section, so that the first external pipe, the inlet section, a portion of the first heat exchange tube, the second manifold, another portion of the first heat exchange tube, the outlet section, and the second external pipe are sequentially connected.

[0009] In one embodiment, the length of the inlet section along the first preset direction is greater than the length of the outlet section along the first preset direction.

[0010] In one embodiment, the external piping assembly further includes a third external piping and a fourth external piping, the third external piping being connected to a third manifold and the fourth external piping being connected to a fourth manifold, such that the fourth external piping, the fourth manifold, the second heat exchange tube, the third manifold, and the third external piping are sequentially connected.

[0011] In one embodiment, the end of the third manifold furthest from the second heat exchanger tube is provided with a first slot, and the end of the first manifold closest to the third manifold is inserted into the first slot and engaged with the third manifold. The end of the fourth manifold furthest from the second heat exchanger tube is provided with a second slot, and the end of the second manifold closest to the fourth manifold is inserted into the second slot and engaged with the fourth manifold.

[0012] In one embodiment, the first manifold has a first opening at one end near the third manifold, and the bottom wall of the first slot covers the first opening and cooperates with the first manifold to form a first manifold channel, with one end of the first heat exchange tube extending into and communicating with the first manifold channel. And / or, the second manifold has a second opening at one end near the fourth manifold, and the bottom wall of the second slot covers the second opening and cooperates with the second manifold to form a second manifold channel, with the other end of the first heat exchange tube extending into and communicating with the second manifold channel.

[0013] In one embodiment, the integrated heat exchanger also includes a water supply pipe that connects to a third manifold.

[0014] This application also provides a thermal management system, which includes the integrated heat exchanger described in any of the above embodiments.

[0015] Compared with the prior art, the integrated heat exchanger and thermal management system provided in this application, as understood, is based on the optimal heat exchange scheme of nesting the first heat exchange tube and the second heat exchange tube together to improve the heat exchange efficiency of the two heat exchange media. However, the integrated heat exchanger provided in this application does not employ the technique of nesting the corresponding manifold assemblies. Instead, the first manifold is directly placed on the side of the third manifold away from the second heat exchange tube, and the first heat exchange tube directly passes through the opposite sidewall of the third manifold and connects to the first manifold (the second manifold is arranged in the same way as the first manifold). Furthermore, since the first, second, third, and fourth manifolds all extend along a first preset direction, the integrated heat exchanger includes, along the first and second ends of the first preset direction, two ends of the first manifold, two ends of the second manifold, two ends of the third manifold, and two ends of the fourth manifold along the first preset direction. Therefore, this configuration ensures that the sidewall of the first manifold between its first and second ends is not completely embedded inside the third manifold. In other words, the external piping connecting the first manifold can be installed in the portion of the first manifold between its first and second ends. Thus, the installation of the external piping does not increase the total length of the integrated heat exchanger along the first preset direction. That is, given a fixed total length of the integrated heat exchanger along the first preset direction, the number of heat exchanger tube assemblies that can be installed in the integrated heat exchanger can reach its maximum value.

[0030] Integrated heat exchangers typically involve the heat exchange of two fluid media. They include an inlet manifold, an outlet manifold, and a heat exchange tube section. External connecting pipes connect the inlet manifold and the outlet manifold, respectively, so that the heat exchange medium enters the heat exchange tube section through the inlet manifold via the external pipe at the inlet end, then enters the outlet manifold from multiple heat exchange tube sections, and flows into the external pipe at the outlet end.

[0031] Furthermore, to facilitate better heat exchange between the two heat exchange media, the heat exchange tubes flowing through them are typically assembled in a nested manner. Correspondingly, the inlet and outlet manifolds for the two heat exchange media are also assembled in a nested manner. These nested manifolds are defined as inner and outer tubes, respectively. To achieve communication between the inner and outer tubes, the outer tube is usually placed at the end of the inner tube. However, the outer tube cannot directly connect to the heat exchange tubes; that is, heat exchange tubes cannot be installed between the outer tubes. Therefore, given a fixed total length of the integrated heat exchanger along the inner tube direction, this arrangement significantly reduces the number of heat exchange tubes that can be assembled in the integrated heat exchanger.

[0032] Please see Figures 1-6 To address the problem that the placement of external piping at the end of the internal pipe significantly reduces the number of heat exchanger tubes that can be installed in an integrated heat exchanger, this application provides an integrated heat exchanger and a thermal management system. The integrated heat exchanger includes a manifold assembly and a heat exchanger tube assembly. Specifically, the manifold assembly includes a first manifold 100, a second manifold 200, a third manifold 300, and a fourth manifold 400. The heat exchanger tube assembly includes a first heat exchanger tube 500 and a second heat exchanger tube 600. The third manifold 300 and the fourth manifold 400 are arranged parallel and spaced apart. A first preset direction is defined for either the length direction of the third manifold 300 or the length direction of the fourth manifold 400. Multiple second heat exchanger tubes 600 are arranged along the first preset direction, and both ends of the multiple second heat exchanger tubes 600 are respectively connected to the third manifold 300 and the fourth manifold 400. The first manifold 100 is located on the side of the third manifold 300 opposite to the second heat exchange tube 600 and extends along a first preset direction. The second manifold 200 is located on the side of the fourth manifold 400 opposite to the second heat exchange tube 600 and extends along the first preset direction. The first heat exchange tube 500 and the second heat exchange tube 600 are arranged in a one-to-one correspondence. The first heat exchange tube 500 is inserted into the second heat exchange tube 600, and one end of the first heat exchange tube 500 passes through the opposite side wall of the third manifold 300 and connects to the first manifold 100. The other end of the first heat exchange tube 500 passes through the opposite side wall of the fourth manifold 400 and connects to the second manifold 200.

[0033] The integrated heat exchanger is defined with two ends along a first preset direction as a first end 710 and a second end 720, respectively. An external pipeline assembly is located between the first end 710 and the second end 720 and is connected to the corresponding manifold assembly.

[0034] It is understandable that, in order to improve the heat exchange efficiency of the two heat exchange media, the first heat exchange tube 500 and the second heat exchange tube 600 are nested together as the optimal heat exchange scheme. Based on this scheme, the integrated heat exchanger provided in this application does not adopt the technical solution of nesting the corresponding manifold components. Instead, the first manifold 100 is directly set on the side of the third manifold 300 away from the second heat exchange tube 600, and the first heat exchange tube 500 directly passes through the opposite side wall of the third manifold 300 and connects to the first manifold 100 (the second manifold 200 is set in the same way as the first manifold 100). Since the first manifold 100, the second manifold 200, the third manifold 300, and the fourth manifold 400 all extend along the first preset direction, the integrated heat exchanger includes, along the first end 710 and the second end 720, the two ends of the first manifold 100, the two ends of the second manifold 200, the two ends of the third manifold 300, and the two ends of the fourth manifold 400 along the first preset direction. Therefore, this arrangement ensures that the sidewall of the first manifold 100 between the first end 710 and the second end 720 is not completely located inside the third manifold 300. In other words, external pipes connecting the first manifold 100 can be installed in the portion of the first manifold 100 located between the first end 710 and the second end 720. Thus, the installation of external pipelines will not increase the total length of the integrated heat exchanger along the first preset direction. That is, when the total length of the integrated heat exchanger along the first preset direction is fixed, the number of heat exchange tube assemblies that can be installed in the integrated heat exchanger can reach the maximum value.

[0035] In summary, the integrated heat exchanger provided in this application solves the problem that the number of heat exchange tubes that can be assembled in the integrated heat exchange device is greatly reduced due to the external pipelines being located at the end of the inner tube.

[0036] In one embodiment, such as Figure 2 and Figure 3 As shown, the third manifold 300 is provided with a first slot 310 at the end away from the second heat exchange tube 600, and the end of the first manifold 100 near the third manifold 300 is inserted into the first slot 310 and connected to the third manifold 300.

[0037] This design reduces the assembly difficulty of the first manifold 100 and the third manifold 300.

[0038] Furthermore, in one embodiment, as Figure 2As shown, the first manifold 100 has a first opening 110 at one end near the third manifold 300, and the bottom wall of the first slot 310 is covered at the first opening 110 and cooperates with the first manifold 100 to form a first manifold channel 120. One end of the first heat exchange tube 500 extends into and connects to the first manifold channel 120.

[0039] This design reduces the weight of the first manifold 100, thereby reducing the weight of the entire integrated heat exchanger.

[0040] Furthermore, in one embodiment, the first manifold 100 and the third manifold 300 are welded together on top of the snap-fit ​​connection.

[0041] This will help to further improve the connection strength between the first manifold 100 and the third manifold 300.

[0042] In one embodiment, such as Figure 2 As shown, the first end 710 of the integrated heat exchanger is provided with a first cover plate 130, and the two ends of the first cover plate 130 are respectively sealed and covered on the first end 710 of the first manifold 100 and the first end 710 of the third manifold 300.

[0043] Similarly, the second end 720 of the integrated heat exchanger is provided with a second cover plate (not shown in the figure), and the two ends of the second cover plate are respectively sealed and covered at the second end 720 of the first manifold 100 and the second end 720 of the third manifold 300.

[0044] This design reduces the processing difficulty of the first manifold 100 and the third manifold 300.

[0045] Furthermore, in one embodiment, as Figure 2 As shown, the first manifold 100 is bent to form a semi-circular pipe with a C-shaped cross-section. The third manifold 300 includes a first sheet metal part 320 and a second sheet metal part 330. The second heat exchange tube 600 passes through the second sheet metal part 330 and is fixedly connected to the second sheet metal part 330. The first sheet metal part 320 connects the first manifold 100 and the second sheet metal part 330, and the side wall of the second sheet metal part 330 away from the second heat exchange tube 600 is bent to form a first groove 310.

[0046] This further reduces the processing difficulty of the first manifold 100 and the third manifold 300.

[0047] Correspondingly, in one embodiment, the end of the fourth manifold 400 away from the second heat exchange tube 600 is provided with a second slot (not shown in the figure), and the end of the second manifold 200 near the fourth manifold 400 is inserted into the second slot and connected to the fourth manifold 400.

[0048] This design reduces the assembly difficulty of the second manifold 200 and the fourth manifold 400.

[0049] Furthermore, in one embodiment, the second manifold 200 has a second opening (not shown) at one end near the fourth manifold 400, and the bottom wall of the second slot is covered at the second opening and cooperates with the second manifold 200 to form a second manifold channel (not shown), and the other end of the first heat exchange tube 500 extends into and connects to the second manifold channel.

[0050] This design reduces the weight of the second manifold 200, thereby reducing the weight of the entire integrated heat exchanger.

[0051] Furthermore, in one embodiment, the second manifold 200 and the fourth manifold 400 are welded on top of the snap-fit ​​connection.

[0052] This will help to further improve the connection strength between the second manifold 200 and the fourth manifold 400.

[0053] In one embodiment, the first end 710 of the integrated heat exchanger is provided with a third cover plate (not shown), and the two ends of the third cover plate are respectively sealed and covered on the first end 710 of the second manifold 200 and the first end 710 of the fourth manifold 400.

[0054] Similarly, the second end 720 of the integrated heat exchanger is provided with a fourth cover plate (not shown in the figure), and the two ends of the fourth cover plate are respectively sealed and covered at the second end 720 of the second manifold 200 and the second end 720 of the fourth manifold 400.

[0055] This design reduces the machining difficulty of the second manifold 200 and the fourth manifold 400.

[0056] Furthermore, in one embodiment, the second manifold 200 is bent to form a semi-circular pipe with a C-shaped cross-section. The fourth manifold 400 includes a third sheet metal part (not shown) and a fourth sheet metal part (not shown). The second heat exchange pipe 600 passes through the fourth sheet metal part and is fixedly connected to the fourth sheet metal part. The third sheet metal part connects the second manifold 200 and the fourth sheet metal part, and the side wall of the fourth sheet metal part away from the second heat exchange pipe 600 is bent to form a second groove.

[0057] This further reduces the processing difficulty of the second manifold 200 and the fourth manifold 400.

[0058] In one embodiment, such as Figure 5 and Figure 6As shown, the first heat exchange tube 500 is provided with a first heat exchange channel 510. The first heat exchange channel 510 is provided with a plurality of first partition strips 520 that are equally spaced and extend along the length of the first heat exchange channel 510, so as to divide the first heat exchange channel 510 into a plurality of parallel and non-communicating first branch channels 530, and the plurality of first branch channels 530 are respectively connected to the first manifold 100 and the second manifold 200.

[0059] Understandably, when the first medium flows within the first heat exchange tube 500, it is easily concentrated at lower heights within the first heat exchange channel 510 due to gravity. This significantly reduces the amount of the first medium at higher heights within the first heat exchange channel 510, leading to uneven distribution of the first medium and affecting its heat exchange efficiency. By setting a first partition bar 520 and dividing the first heat exchange channel 510 into multiple non-interconnected first branch channels 530, the first medium within each branch channel 530 can independently complete heat exchange, preventing the first medium from converging within the first heat exchange channel 510 and thus affecting the heat exchange efficiency of the first heat exchange tube 500.

[0060] Furthermore, in one embodiment, as Figure 5 and Figure 6 As shown, the outer wall of the first heat exchange tube 500 and the inner wall of the second heat exchange tube 600 are spaced apart to form a second heat exchange channel 610. The second heat exchange channel 610 is provided with a plurality of second partition strips 620 extending along the length of the second heat exchange channel 610 to divide the second heat exchange channel 610 into a plurality of parallel and non-communicating second branch channels 630, and the plurality of second branch channels 630 are respectively connected to the third manifold 300 and the fourth manifold 400.

[0061] Understandably, when the second medium flows within the second heat exchange tube 600, it is also prone to convergence due to gravity at lower heights within the second heat exchange channel 610. This results in a significant reduction in the amount of the second medium at higher heights within the second heat exchange channel 610, leading to uneven distribution of the second medium within the first heat exchange channel 510 and consequently affecting its heat exchange efficiency. By setting a second partition bar 620 and dividing the second heat exchange channel 610 into multiple non-interconnected second branch channels 630, the second medium within the second branch channels 630 can independently complete heat exchange, preventing convergence within the second heat exchange channel 610 and thus avoiding impact on the heat exchange efficiency of the second heat exchange tube 600.

[0062] Furthermore, the first partition bar 520 can also provide support and positioning for the first heat exchange tube 500.

[0063] Furthermore, in one embodiment, the arrangement direction of the plurality of first branch channels 530 is defined as a second preset direction, and the plurality of second partition bars 620 are distributed in the second heat exchange channel 610 along the second preset direction, and the spacing between adjacent second partition bars 620 decreases along the direction extending from the middle to both ends.

[0064] This helps to further improve the uniform distribution of the second medium within the second heat exchange channel 610.

[0065] In one embodiment, such as Figure 4 As shown, the first manifold 100 is provided with a first baffle 140 to divide the first manifold 100 into an inlet section 150 and an outlet section 160. The external piping assembly includes a first external piping 810 and a second external piping 820. The first external piping 810 is connected to the inlet section 150, and the second external piping 820 is connected to the outlet section 160, so that the first external piping 810, the inlet section 150, a portion of the first heat exchange tube 500, the second manifold 200, another portion of the first heat exchange tube 500, the outlet section 160, and the second external piping 820 are sequentially connected.

[0066] In this way, the entire flow channel of the first medium can become a C-shaped meandering channel, which is beneficial for the first external pipeline 810 and the second external pipeline 820 to be set on the same side.

[0067] Furthermore, in one embodiment, as Figure 4 As shown, the length of the inlet section 150 along the first preset direction is greater than the length of the outlet section 160 along the first preset direction.

[0068] Typically, the first medium entering the first heat exchange tube 500 is in a gas-liquid two-phase state, at which point its total volume is relatively large. Finally, the first medium leaving the first heat exchange tube 500 is in a liquid state, at which point its total volume is relatively small. Therefore, this arrangement helps maintain a balance between the total amount of the first medium entering the liquid inlet section 150 and the total amount leaving the liquid outlet section 160, thereby improving the heat exchange efficiency of the integrated heat exchanger.

[0069] In one embodiment, such as Figure 1 As shown, the external piping assembly also includes a third external piping 830 and a fourth external piping 840. The third external piping 830 is connected to the third manifold 300, and the fourth external piping 840 is connected to the fourth manifold 400, so that the fourth external piping 840, the fourth manifold 400, the second heat exchange tube 600, the third manifold 300, and the third external piping 830 are connected in sequence.

[0070] Thus, the inlet direction of the first medium is opposite to that of the second medium, which is beneficial to improving the heat exchange efficiency of the first and second media.

[0071] In one embodiment, such as Figure 1 As shown, a temperature sensor 900 is provided at the fourth manifold 400, and the temperature sensor 900 is located on one side of the fourth external pipeline 840 to detect the temperature value of the second medium at the fourth manifold 400.

[0072] In one embodiment, such as Figure 1 As shown, the integrated heat exchanger also includes a water supply pipe 850, which is connected to the third manifold 300.

[0073] With this setup, the second medium can be replenished in a timely manner through the water supply pipe 850.

[0074] This application also provides a thermal management system, which includes the integrated heat exchanger described in any of the above embodiments.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
