Description

Technical Field

[0001] This application relates to the field of heat exchange technology, and more particularly to a heat exchanger for vehicles. Background Technology

[0002] Heat exchangers, also known as heat exchangers, are widely used in heat exchange systems (such as air conditioning systems). Heat exchangers can be used for heat exchange between a heat exchange medium and outside air, or for heat exchange between two heat exchange media.

[0003] In related technologies, a heat exchanger includes a first manifold assembly and a heat exchange core. The first manifold assembly includes a first manifold tube and a first base plate, which are sealed together. The first manifold assembly has a first chamber. The heat exchange core includes multiple heat exchange tubes, the lumens of which communicate with the first chamber. During operation, the heat exchange medium entering the first chamber is prone to uneven distribution, resulting in some heat exchange tubes receiving more heat exchange medium than others. Consequently, some heat exchange areas are not fully utilized, preventing the heat exchanger from achieving its full performance and negatively impacting the heat exchange effect. Summary of the Invention

[0004] The following technical solution is adopted in this application:

[0005] A heat exchanger includes a first manifold assembly and a heat exchange core. The first manifold assembly is fixedly connected to the heat exchange core. The first manifold assembly includes a first manifold pipe, a first base plate, and a first partition plate. The first manifold pipe and the first base plate are sealed together. The first base plate includes a plurality of first protrusions. Each first protrusion has a first mounting groove. A portion of the first partition plate is located in the first mounting groove. The first manifold pipe and the groove wall of the first mounting groove are respectively limited and connected to the first partition plate.

[0006] The first current collection assembly has a first chamber, and the heat exchange core includes a plurality of heat exchange tubes. The lumen of the heat exchange tubes is connected to the first chamber. The first chamber includes a first distribution chamber, a second distribution chamber, and a first connecting channel. The first distribution chamber and the second distribution chamber are respectively located on both sides of the thickness direction of the first partition plate, and the first connecting channel is located on one side of the length direction of the first partition plate. Both the first distribution chamber and the second distribution chamber are connected to the first connecting channel.

[0007] In this application, the walls of the first manifold and the first mounting groove are respectively connected to the first partition plate for limiting. The first distribution cavity and the second distribution cavity are located on both sides of the thickness direction of the first partition plate, and the first connecting channel is located on one side of the length direction of the first partition plate. Through the limiting cooperation between the first manifold, the first protrusion of the first base plate, and the first partition plate, the first chamber of the first manifold assembly is divided into the first distribution cavity, the second distribution cavity, and the first connecting channel. The first distribution cavity and the second distribution cavity are both connected to the first connecting channel to form a distribution loop. This is beneficial to improving the uniformity of heat exchange medium distribution in the first chamber, so that the heat exchange medium can be more evenly distributed from the first chamber to the cavity of each heat exchange tube, thereby improving the heat exchange effect of the heat exchanger.

Detailed Implementation

[0022] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0023] It should be understood that the described embodiments are merely some embodiments of this application, and not all embodiments. All other technical solutions obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The heat exchanger of an exemplary embodiment of this application will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and features in the implementation methods can complement or combine with each other.

[0024] According to one possible embodiment of the heat exchanger of this application, refer to Figures 1 to 12 As shown, a heat exchanger includes a first manifold assembly 10 and a heat exchange core 20. The first manifold assembly 10 is fixedly connected to the heat exchange core 20. The first manifold assembly 10 includes a first manifold pipe 11, a first base plate 12 and a first partition plate 13. The first manifold pipe 11 and the first base plate 12 are sealed together. The first base plate 12 includes a plurality of first protrusions 121. The first protrusions 121 have a first mounting groove 1210. A portion of the first partition plate 13 is located in the first mounting groove 1210. The groove walls of the first manifold pipe 11 and the first mounting groove 1210 are respectively limited and connected to the first partition plate 13.

[0025] The first collector assembly 10 has a first chamber 101. The heat exchange core 20 includes a plurality of heat exchange tubes 21. The lumen of the heat exchange tubes 21 is connected to the first chamber 101. The first chamber 101 includes a first distribution chamber 1011, a second distribution chamber 1012 and a first connecting channel 1013. The first distribution chamber 1011 and the second distribution chamber 1012 are respectively located on both sides of the thickness direction of the first partition plate 13. The first connecting channel 1013 is located on one side of the length direction of the first partition plate 13. The first distribution chamber 1011 and the second distribution chamber 1012 are both connected to the first connecting channel 1013.

[0026] In this application, the walls of the first manifold 11 and the first mounting groove 1210 are respectively limited and connected to the first partition plate 13, the first distribution cavity 1011 and the second distribution cavity 1012 are respectively located on both sides of the thickness direction of the first partition plate 13, and the first connecting channel 1013 is located on one side of the length direction of the first partition plate 13. Through the limiting cooperation between the first manifold 11, the first base plate 12, and the first partition plate 13, the first chamber 101 of the first manifold assembly 10 is divided into a first distribution chamber 1011, a second distribution chamber 1012, and a first connecting channel 1013. The first distribution chamber 1011 and the second distribution chamber 1012 are both connected to the first connecting channel 1013, forming a roughly U-shaped distribution loop. This is beneficial to improving the uniformity of heat exchange medium distribution in the first chamber 101. Furthermore, the flow area of ​​the first distribution chamber 1011, the second distribution chamber 1012, and the first connecting channel 1013 is relatively small compared to the first chamber 101. That is, the arrangement of the first distribution chamber 1011, the second distribution chamber 1012, and the first connecting channel 1013 relatively reduces the flow area, increases the flow velocity of the heat exchange medium, and further improves the uniformity of heat exchange medium distribution in the first chamber 101. This allows the heat exchange medium to be evenly distributed from the first chamber 101 to the cavity of each heat exchange tube, thereby improving the heat exchange effect of the heat exchanger.

[0027] Reference Figure 3 and Figure 11 As shown, the first manifold 11, the first base plate 12, and the first partition plate 13 are assembled separately, which has good applicability and is relatively simple to process and form. The first protrusion 121 has a first mounting groove 1210, and part of the first partition plate 13 is located in the first mounting groove 1210. The groove wall of the first mounting groove 1210 is connected to the first partition plate 13 for limiting. The first partition plate 13 is limited by the setting of the first mounting groove 1210. The connection stability of the first manifold 11, the first base plate 12, and the first partition plate 13 is good and easy to assemble.

[0028] The first manifold 11 has a second mounting groove 110 extending along the length of the first manifold 11. The first mounting groove 1210 and the second mounting groove 110 are located on both sides of the width direction of the first partition plate 13. A portion of the first partition plate 13 is located in the second mounting groove 110, and the first partition plate 13 is connected to the groove wall of the second mounting groove 110 with limiting connection. The second mounting groove 110 further limits the first partition plate 13. The groove walls of the first mounting groove 1210 and the second mounting groove 110 together achieve bidirectional limiting of the first partition plate 13, further improving the connection stability of the first manifold 11, the first base plate 12, and the first partition plate 13, and facilitating assembly.

[0029] Reference Figure 3 , Figure 4 and Figure 11As shown, the first manifold 11 includes a plurality of first protrusions 111 and second protrusions 112. The plurality of first protrusions 111 are spaced apart along the length direction of the first manifold 11, and the plurality of second protrusions 112 are spaced apart along the length direction of the first manifold 11. The first protrusions 111 protrude from the inner wall of the first manifold 11 towards the first protrusion 121, and the second protrusions 112 protrude from the inner wall of the first manifold 11 towards the first protrusion 121. Along the thickness direction of the first partition plate 13, the first protrusions 111 and second protrusions 112 are respectively located on both sides of the first protrusion 121, and the first protrusions 111 and second protrusions 112 are respectively connected to the first protrusion 121 for limiting. The first protrusions 111 and second protrusions 112 respectively contact and engage with the opposite sides of the first protrusion 121. The limiting connection of the first boss 111, the second boss 112, and the first boss 121 helps to improve the connection stability of the first manifold 11, the first base plate 12, and the first partition plate 13, and facilitates accurate assembly.

[0030] Along the length of the first base plate 12, a plurality of first protrusions 121 are spaced apart, and a first mounting groove 1210 passes through the first protrusions 121. All the first mounting grooves 1210 extend along the length of the first base plate 12. The first base plate 12 includes a first main body 122, and the first protrusions 121 protrude from the first main body 122 toward the first partition plate 13. The first main body 122 and the first protrusions 121 are an integral structure, and the connection stability between the first main body 122 and the first protrusions 121 is good.

[0031] The first manifold 11, the first base plate 12, and the first partition plate 13 are all made of aluminum alloy, providing good structural strength. The first manifold 11, the first base plate 12, and the first partition plate 13 are all integral structures, resulting in good structural stability. The method of forming these integral structures is not specifically limited; they can be formed using one or a combination of stamping, extrusion, casting, powder metallurgy, metal powder injection molding, 3D printing, etc. Alternatively, they can be formed by stamping, extrusion, casting, powder metallurgy, or metal powder injection molding followed by machining, or they can be directly machined.

[0032] Reference Figure 3 , Figure 4 , Figure 8 and Figure 11As shown, multiple heat exchange tubes 21 are spaced apart along the length of the first base plate 12. The first base plate 12 has multiple first mounting holes 123, which are spaced apart along the length of the first base plate 12. The first mounting holes 123 penetrate both sides of the first base plate 12 in the thickness direction. The heat exchange tubes 21 pass through the first mounting holes 123 and are sealed to the hole walls of the first mounting holes 123. One end of the heat exchange tube 21 is located in the first chamber 101. A first protrusion 121 is located between two adjacent first mounting holes 123; in other words, the first protrusion 121 is located between the tube ends of two adjacent heat exchange tubes 21. There is a gap between the sidewall of the heat exchange tube 21 and the first protrusion 121. The first manifold assembly 10 has multiple grooves located between the tube ends of two adjacent heat exchange tubes 21, and the first protrusion 121 is at least partially located in these grooves.

[0033] The heat exchange tube 21 is made of aluminum alloy and is a porous tube. The heat exchange core 20 includes fins 22, which are located between two adjacent heat exchange tubes 21 and are fixedly connected to the two adjacent heat exchange tubes 21. The fins 22 have a corrugated structure and are made of metal. The fins 22 can increase the heat exchange area of ​​the heat exchange core 20, thereby improving the heat exchange efficiency of the heat exchanger, and can also increase the structural strength of the heat exchange core 20.

[0034] The heat exchange tube 21 passes through and extends out of the first mounting hole 123. One end of the heat exchange tube 21 is located in the first chamber 101. A groove is formed between the ends of two adjacent heat exchange tubes 21. If the first protrusion 121 is not provided, the heat exchange tube 21 may interfere with the first partition plate 13, making it difficult to assemble the first partition plate 13 and the first base plate 12. Furthermore, if the first protrusion 121 is not provided, the heat exchange medium will stagnate or form eddies in the groove during its flow in the first chamber 101, resulting in greater flow resistance and making it difficult for the heat exchange medium to reach the end, leading to poor distribution uniformity. The first protrusion 121 is located between the ends of two adjacent heat exchange tubes 21.

[0035] The first protrusion 121 facilitates the assembly of the first partition plate 13 and the first base plate 12, preventing interference between the heat exchange tube 21 and the first partition plate 13. Furthermore, the first protrusion 121 fills at least part of the groove between the ends of two adjacent heat exchange tubes 21, reducing the volume of the groove and thus decreasing the flow resistance of the heat exchange medium in the first chamber 101. This allows the heat exchange medium to reach the end smoothly and improves the uniformity of its distribution within the first chamber 101. Additionally, the first protrusion 121 enhances the structural strength of the first base plate 12, resulting in better structural stability.

[0036] The first boss 111 is located between two adjacent first mounting holes 123, and the second boss 112 is located between two adjacent first mounting holes 123. There is a gap between the sidewall of the heat exchange tube 21 and the first boss 111, and a gap between the sidewall of the heat exchange tube 21 and the second boss 112. A cavity is formed between two adjacent first bosses 111, and a portion of the tube end of the heat exchange tube 21 is located in this cavity. A cavity is formed between two adjacent second bosses 112, and a portion of the tube end of the heat exchange tube 21 is located in this cavity. The two adjacent first bosses 111 and the second boss 112 are aligned along the thickness direction of the first partition plate 13.

[0037] The limiting connection of the first protrusion 111, the second protrusion 112, and the first protrusion 121 not only improves the connection stability of the first manifold 11, the first base plate 12, and the first partition plate 13, but also allows the first and second protrusions to partially fill the groove between the ends of adjacent heat exchange tubes 21. This reduces the volume of the groove between the ends of adjacent heat exchange tubes 21, thereby reducing the flow resistance of the heat exchange medium in the first chamber 101, allowing the heat exchange medium to reach the end smoothly, and improving the uniformity of heat exchange medium distribution in the first chamber 101. Furthermore, the first and second protrusions 111 and 112 improve the structural strength of the first manifold 11, resulting in better structural stability.

[0038] Reference Figure 3 , Figure 4 , Figure 8 and Figure 12 As shown, the first manifold 11 includes a plurality of first snap-fit ​​parts 113, which are spaced apart and evenly spaced. Each first snap-fit ​​part 113 has a first slot 1131. A portion of the first base plate 12 is located in the first slot 1131, and the first base plate 12 abuts against the wall of the first slot 1131. The arrangement of the first snap-fit ​​parts 113 can improve the connection stability and sealing of the first manifold 11 and the first base plate 12.

[0039] Reference Figure 3 , Figure 4 , Figure 8 and Figure 11As shown, the first chamber 101 is located between the first manifold 11 and the first base plate 12, and the first partition plate 13 is at least partially located in the first chamber 101. The first chamber 101 includes a plurality of first channels 1014, which are spaced apart along the length of the first base plate 12. The first channels 1014 are located between the heat exchange tube 21 and the adjacent first protrusion 121. The first distribution chamber 1011 and the second distribution chamber 1012 communicate with the plurality of first channels 1014. The first channels 1014 are approximately parallel to the thickness direction of the first partition plate 13, the first connecting channel 1013 is approximately parallel to the thickness direction of the first partition plate 13, the first distribution chamber 1011 is approximately parallel to the length direction of the first partition plate 13, and the second distribution chamber 1012 is approximately parallel to the length direction of the first partition plate 13. The length direction, width direction, and thickness direction of the first partition plate 13 are perpendicular to each other. The length direction of the first base plate 12 is parallel to the length direction of the first partition plate 13, and the length direction of the first manifold 11 is parallel to the length direction of the first partition plate 13.

[0040] Both the first distribution chamber 1011 and the second distribution chamber 1012 are connected to the first connecting channel 1013, forming a roughly U-shaped main distribution flow path. The first distribution chamber 1011 and the second distribution chamber 1012 are connected to multiple first channels 1014, forming multiple compensating distribution flow paths, which further improves the uniformity of heat exchange medium distribution in the first chamber 101, allowing the heat exchange medium to be evenly distributed from the first chamber 101 to the lumen of each heat exchange tube, thereby improving the heat exchange effect of the heat exchanger.

[0041] Reference Figure 3 , Figure 4 , Figure 8 , Figure 10 and Figure 12As shown, the first current collection assembly 10 includes a first partition plate 14 and a first end plate 15. The first partition plate 14 and the first end plate 15 are respectively located on both sides of the length direction of the first partition plate 13. The first current collection pipe 11 and the first bottom plate 12 are both fixedly connected to the first partition plate 14. Specifically, the first current collection pipe 11 and the first bottom plate 12 are both welded and fixed to the first partition plate 14, and the first current collection pipe 11 and the first bottom plate 12 are both sealed and connected to the first partition plate 14. The first current collection pipe 11 and the first bottom plate 12 are both fixedly connected to the first end plate 15. Specifically, the first current collection pipe 11 and the first bottom plate 12 are both welded and fixed to the first end plate 15, and the first current collection pipe 11 and the first bottom plate 12 are both sealed and connected to the first end plate 15. The first partition plate 14 has a first mounting hole 141. A portion of the first partition plate 13 is located within the first mounting hole 141. One end of the first partition plate 13 is connected to the wall of the first mounting hole 141, and the other end of the first partition plate 13 has a gap with the first end plate 15. A first connecting channel 1013 is located between the first partition plate 13 and the first end plate 15; that is, the gap between the other end of the first partition plate 13 and the first end plate 15 forms the first connecting channel 1013. The first mounting hole 141 is rectangular in shape, and the first partition plate 13 has a cuboid structure. The first manifold 11 has a first fixing hole, and the first base plate 12 has a second fixing hole. The walls of the first fixing hole and the second fixing hole respectively mate with both ends of the first partition plate 14. The walls of the first fixing hole and the second fixing hole are welded and fixed to both ends of the first partition plate 14.

[0042] The first partition plate 14 is provided with a first assembly hole 141 to realize the limiting connection between the first partition plate 13 and the first partition plate 14. At the same time, the length of the first partition plate 13 inserted into the first assembly hole 141 can also adjust the gap size of the first end plate 15 at the end of the first partition plate 13. In other words, the length of the first partition plate 13 inserted into the first assembly hole 141 can adjust the flow area of ​​the first connecting channel 1013, so as to realize different distribution effects of the heat exchange medium in the first chamber 101 by the first partition plate 13.

[0043] The first current collection assembly 10 also includes a third end plate 16. The first end plate 15 and the third end plate 16 are located on both sides of the thickness direction of the first middle partition 14, and the first current collection pipe 11 and the first bottom plate 12 are both sealed to the third end plate 16.

[0044] The first collector assembly 10 has a second chamber 102 located between the first collector pipe 11 and the first base plate 12. A first partition plate 14 divides the inner cavity of the first collector assembly 10 into a first chamber 101 and a second chamber 102, located on opposite sides of the first partition plate 14 in the thickness direction. The first partition plate 14 has a connecting hole 142, through which the second chamber 102 and the first distribution chamber 1011 are connected. The second chamber 102 and the second distribution chamber 1012 are isolated at the first partition plate 14. The flow area of ​​the connecting hole 142 is smaller than that of the second chamber 102, thus reducing the flow area of ​​the heat exchange medium flowing from the second chamber 102 into the first chamber 101. This increases the flow velocity of the heat exchange medium flowing into the first chamber 101, allowing it to reach the end smoothly and improving the distribution effect of the heat exchange medium in the first chamber 101.

[0045] The first base plate 12 also includes third protrusions 124. Multiple third protrusions 124 are spaced apart along the length of the first base plate 12. Each third protrusion 124 protrudes from the first main body 122 toward the first partition plate 13. The first main body 122 and the third protrusions 124 are an integral structure. The first protrusion 121 and the third protrusion 124 are located on opposite sides of the thickness of the first partition plate 14. The first protrusion 121 is located in the first chamber 101, and the third protrusion 124 is located in the second chamber 102.

[0046] The first protrusion 111 and the second protrusion 112 are located on both sides of the third protrusion 124, and are respectively connected to the third protrusion 124 for limiting. The first protrusion 111 and the second protrusion 112 are in contact with the opposite sides of the third protrusion 124. The limiting connection of the first protrusion 111, the second protrusion 112, and the third protrusion 124 helps to improve the connection stability of the first manifold 11, the first base plate 12, and the first partition plate 13, and facilitates accurate assembly. Furthermore, the third protrusion 124 can fill at least part of the groove between the ends of two adjacent heat exchange tubes 21, thereby reducing the volume of the groove between the ends of two adjacent heat exchange tubes 21, thus reducing the flow resistance of the heat exchange medium in the second chamber 102, allowing the heat exchange medium to reach the end smoothly. In addition, the third protrusion 124 can improve the structural strength of the first base plate 12, resulting in better structural stability.

[0047] Reference Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 9As shown, the heat exchanger includes a second manifold assembly 30. The first manifold assembly 10 and the second manifold assembly 30 are located on both sides of the heat exchange core 20, and the heat exchange core 20 is fixedly connected to the second manifold assembly 30. The second manifold assembly 30 includes a second manifold pipe 31, a second base plate 32, a second partition plate 33, a second middle partition plate 34, and a second end plate 35. The second manifold pipe 31 is sealed to the second base plate 32. The second manifold pipe 31 and the second base plate 32 are fixedly connected to the second middle partition plate 34, and the second manifold pipe 31 and the second base plate 32 are respectively limited to the second partition plate 33. The second middle partition plate 34 is connected to the second partition plate 33, and the second manifold pipe 31 and the second base plate 32 are respectively fixedly connected to the second end plate 35. The second collector assembly 30 has a third chamber 301 and a fourth chamber 302, which are isolated at the second partition plate 34. The third chamber 301 is connected to the second chamber 102 through a portion of the lumen of the heat exchange tube 21, and the first chamber 101 is connected to the fourth chamber 302 through a portion of the lumen of the heat exchange tube 21.

[0048] The third chamber 301 includes a third distribution chamber 3011, a fourth distribution chamber 3012, and a second connecting channel 3013. The third distribution chamber 3011 and the fourth distribution chamber 3012 are located on both sides of the thickness direction of the second partition plate 33, and the second connecting channel 3013 is located between the second partition plate 33 and the second end plate 35. Both the third distribution chamber 3011 and the fourth distribution chamber 3012 are connected to the second connecting channel 3013.

[0049] Through the limiting cooperation between the second manifold 31, the second base plate 32, and the second partition plate 33, the third chamber 301 of the second manifold assembly 30 is divided into a third distribution chamber 3011, a fourth distribution chamber 3012, and a second connecting channel 3013. The third distribution chamber 3011 and the fourth distribution chamber 3012 are both connected to the second connecting channel 3013, forming a roughly U-shaped distribution loop. This is beneficial to improving the uniformity of heat exchange medium distribution in the third chamber 301. Furthermore, the flow area of ​​the third distribution chamber 3011, the fourth distribution chamber 3012, and the second connecting channel 3013 is relatively small compared to the third chamber 301, which reduces the flow area and increases the flow velocity of the heat exchange medium. This further improves the uniformity of heat exchange medium distribution in the third chamber 301, allowing the heat exchange medium to be evenly distributed from the third chamber 301 to the cavity of each heat exchange tube, thereby improving the heat exchange effect of the heat exchanger.

[0050] Reference Figure 2 , Figure 5 , Figure 6 and Figure 9As shown, the second base plate 32 includes a plurality of second protrusions 321, which are spaced apart along the length of the second base plate 32. Each second protrusion 321 has a third mounting groove 3210, and the second manifold 31 has a fourth mounting groove 310. A portion of the second partition plate 33 is located in the third mounting groove 3210, and a portion of the second partition plate 33 is located in the fourth mounting groove 310. The second partition plate 33 abuts against the groove wall of both the third and fourth mounting grooves. The second base plate 32 also has a plurality of second mounting holes 323, which are evenly spaced along the length of the second base plate 32. One end of the heat exchange tube 21 passes through a second mounting hole 323, and the heat exchange tube 21 is sealed to the hole wall of the second mounting hole 323. A second protrusion 321 is located between two adjacent second mounting holes 323, and a gap exists between the sidewall of the heat exchange tube 21 and the second protrusion 321.

[0051] The second manifold 31 includes a plurality of third protrusions 311 and fourth protrusions 312. The third protrusions 311 and fourth protrusions 312 are spaced apart along the length of the second manifold 31. The third protrusions 311 protrude from the inner wall of the second manifold 31 towards the second protrusion 321, and the fourth protrusions 312 protrude from the inner wall of the second manifold 31 towards the second protrusion 321. Along the thickness direction of the second partition plate 33, the third protrusions 311 and fourth protrusions 312 are located on opposite sides of the second protrusion 321, and are respectively positioned and connected to the second protrusion 321. The third protrusions 311 and fourth protrusions 312 are in contact with opposite sides of the second protrusion 321.

[0052] The third boss 311 is located between two adjacent second mounting holes 323, and the fourth boss 312 is located between two adjacent second mounting holes 323. There is a gap between the sidewall of the heat exchange tube 21 and the third boss 311, and a gap between the sidewall of the heat exchange tube 21 and the fourth boss 312. A cavity is formed between two adjacent third bosses 311, and a portion of the tube end of the heat exchange tube 21 is located in this cavity. A cavity is formed between two adjacent fourth bosses 312, and a portion of the tube end of the heat exchange tube 21 is located in this cavity. The adjacent third bosses 311 and fourth bosses 312 are aligned along the thickness direction of the second partition plate 33.

[0053] The limiting connection between the third protrusion 311, the fourth protrusion 312, and the second protrusion 321 not only improves the connection stability of the second manifold assembly 30, but also enhances its structural stability. The second manifold assembly 30 has multiple grooves located between the ends of adjacent heat exchange tubes 21. Parts of the third protrusion 311 and the fourth protrusion 312 are located within these grooves, and at least part of the second protrusion 321 is also located within them. This arrangement of the third protrusion 311, the fourth protrusion 312, and the second protrusion 321 can fill at least part of the groove between the ends of adjacent heat exchange tubes 21, reducing the volume of the groove between the ends of adjacent heat exchange tubes 21. This reduces the flow resistance of the heat exchange medium in the third chamber 301, allowing the heat exchange medium to reach the end smoothly and improving the uniformity of heat exchange medium distribution in the third chamber 301. Furthermore, the second protrusion 321 improves the structural strength of the second base plate 32, and the third protrusion 311 and the fourth protrusion 312 improve the structural strength of the second manifold 31, resulting in better structural stability.

[0054] Reference Figure 6 and Figure 12 As shown, the second manifold 31 includes a plurality of second snap-fit ​​portions 316, which are spaced apart and evenly spaced. Each second snap-fit ​​portion 316 has a second slot 3161, and a portion of the second base plate 32 is located in the second slot 3161. The second base plate 32 abuts against the wall of the second slot 3161. The arrangement of the second snap-fit ​​portions 316 can improve the connection stability and sealing of the second manifold 31 and the second base plate 32.

[0055] Reference Figure 2 , Figure 5 , Figure 6 and Figure 9 As shown, the third chamber 301 includes a plurality of second channels 3014, which are spaced apart along the length of the second base plate 32. The second channels 3014 are located between the heat exchange tube 21 and the adjacent second protrusion 321. The third distribution chamber 3011 and the fourth distribution chamber 3012 are connected to the plurality of second channels 3014.

[0056] The second channel 3014 is approximately parallel to the thickness direction of the second partition plate 33; the second connecting channel 3013 is approximately parallel to the thickness direction of the second partition plate 33; the third distribution cavity 3011 is approximately parallel to the length direction of the second partition plate 33; and the fourth distribution cavity 3012 is approximately parallel to the length direction of the second partition plate 33. The length, width, and thickness directions of the second partition plate 33 are perpendicular to each other. The length direction of the second base plate 32 is parallel to the length direction of the second partition plate 33, and the length direction of the second manifold 31 is parallel to the length direction of the second partition plate 33.

[0057] Both the third distribution chamber 3011 and the fourth distribution chamber 3012 are connected to the second connecting channel 3013, forming a roughly U-shaped main distribution flow path. The third distribution chamber 3011 and the fourth distribution chamber 3012 are connected to multiple second channels 3014, forming multiple compensating distribution flow paths, which further improves the uniformity of heat exchange medium distribution in the third chamber 301, allowing the heat exchange medium to be evenly distributed from the third chamber 301 to the cavity of each heat exchange tube, thereby improving the heat exchanger's heat exchange effect.

[0058] Reference Figure 2 , Figure 5 , Figure 6 and Figure 9 As shown, the second base plate 32 also includes a fourth protrusion 324. Multiple fourth protrusions 324 are spaced apart along the length of the second base plate 32. The second base plate 32 includes a second main body 322. Second protrusions 321 protrude from the second main body 322 towards the first partition plate 13, and fourth protrusions 324 protrude from the second main body 322 towards the first partition plate 13. The second protrusions 321 and 324 are located on opposite sides of the thickness of the second partition plate 34. The second protrusion 321 is located in the third chamber 301, and the fourth protrusion 324 is located in the second chamber 102.

[0059] The third protrusion 311 and the fourth protrusion 312 are located on both sides of the fourth protrusion 324, and are respectively connected to the fourth protrusion 324 for limiting. The third protrusion 311 and the fourth protrusion 312 are in contact with the opposite sides of the fourth protrusion 324. The limiting connection of the third protrusion 311, the fourth protrusion 312, and the fourth protrusion 324 helps to improve the connection stability of the first manifold 11, the second base plate 32, and the first partition plate 13, and facilitates accurate assembly. Furthermore, the fourth protrusion 324 can fill at least part of the groove between the ends of two adjacent heat exchange tubes 21, thereby reducing the volume of the groove between the ends of two adjacent heat exchange tubes 21 and reducing the flow resistance of the heat exchange medium in the fourth chamber 302. In addition, the fourth protrusion 324 can improve the structural strength of the second base plate 32, resulting in better structural stability.

[0060] The second manifold 31, the second base plate 32, and the second partition plate 33 are all made of aluminum alloy, providing good structural strength. The second manifold 31, the second base plate 32, and the second partition plate 33 are all integral structures, resulting in good structural stability.

[0061] Reference Figure 2 , Figure 5 , Figure 6 and Figure 9As shown, the second current collection assembly 30 also includes a fourth end plate 36. The second end plate 35 and the fourth end plate 36 are located on both sides of the thickness direction of the second middle partition 34, and the second current collection pipe 31 and the second bottom plate 32 are both sealed to the fourth end plate 36.

[0062] The second manifold 31 has a first external connection hole 314 and a second external connection hole 315. The heat exchanger includes a first pressure block 40 and a second pressure block 50. Both the first pressure block 40 and the second pressure block 50 are sealed to the second manifold 31 and fixedly connected to the second manifold 31. The inner cavity of the first pressure block 40 communicates with the first external connection hole 314, which communicates with the third chamber 301. The inner cavity of the second pressure block 50 communicates with the second external connection hole 315, and the channel of the second external connection hole 315 communicates with the fourth chamber 302.

[0063] Reference Figures 7 to 9 As shown, when the heat exchanger is working, the heat exchange medium flows into the third chamber 301 from the first external connection hole 314 of the second manifold 31. It then passes through the U-shaped main distribution path formed by the third distribution chamber 3011, the fourth distribution chamber 3012, and the second connecting channel 3013, as well as the compensation path formed by multiple roughly parallel second channels 3014. The medium is evenly distributed into the cavity of the heat exchange tube 21, which is connected to the third chamber 301. During its flow through the cavity of the heat exchange tube 21, it exchanges heat with the air and then flows into the second chamber 102. The heat exchange medium in the second chamber 102 flows into the first chamber 101 through the connecting hole 142 of the first partition plate 14. It is then evenly distributed into the cavity of the heat exchange tube 21 connected to the first chamber 101 by the U-shaped main distribution flow path formed by the first distribution cavity 1011, the second distribution cavity 1012 and the first connecting channel 1013, as well as the compensation flow path formed by multiple roughly parallel first channels 1014. During the flow through the cavity of the heat exchange tube 21, it exchanges heat with the air and finally flows into the fourth chamber 302, thus circulating.
