Description

Technical Field

[0001] The present application relates to the field of heat exchange technology, and in particular to a heat exchanger. Background Art

[0002] Heat exchangers, also known as heat exchangers, are widely used in heat exchange systems. Heat exchangers can be used for heat exchange between a heat exchange medium and external air, and can also be used for heat exchange between two heat exchange media. In the related art, the water chamber shell and the mainboard of the heat exchanger have no buckling and positioning structure. When the mainboard claws are buckled with the water chamber shell, the buckling height can only be set by the buckling device to determine the compression amount of the sealing ring. This buckling method requires the buckling device to be well positioned and stable. In actual operation, due to operator errors, unstable buckling equipment, etc., the positional relationship between the water chamber shell and the mainboard is unstable, which makes the compression amount of the sealing ring between the water chamber shell and the mainboard difficult to control, affecting the sealing effect. Summary of the Invention

[0004] A heat exchanger comprises a plurality of heat exchange tubes, a first component, a second component and a first seal, wherein the first component is connected to the second component, the first seal is located between the first component and the second component, and the heat exchange tubes are connected to the second component;

[0005] The heat exchanger has a first manifold located between the first component and the second component;

[0006] The first component includes a first protrusion and a first manifold wall, the first protrusion circumferentially surrounds the first manifold wall, the first protrusion protrudes from the outer wall of the first component in a direction away from the first manifold, and the first protrusion is connected to the second component;

[0007] The first component further includes at least one second protrusion, along the protruding direction of the first protrusion, at least part of the second protrusion protrudes from the first protrusion in a direction away from the first manifold, and at least part of the first protrusion abuts against the second component;

[0008] The second component has at least one positioning groove, and the second protrusion is located in the positioning groove.

[0025] The heat exchanger of the exemplary embodiment of the present application is described in detail below with reference to the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can complement or be combined with each other.

[0026] Figures 1 to 12 1 shows the heat exchanger and its components in some embodiments of the present application. Figure 1 and Figure 2 As shown, the heat exchanger includes a first collector, a second collector, and a main body 1. The main body 1 is partially located between the first and second collectors. The main body 1 primarily functions as a heat exchanger. One side of the main body 1 is connected to the second collector, and the other side is connected to the first collector. The first and second collectors are located on different sides of the main body 1. Both the first and second collectors are used to collect and distribute liquids, allowing the fluid to circulate within the heat exchanger.

[0027] like Figure 1 and Figure 2As shown, the main body 1 includes a plurality of heat exchange tubes 11. When the heat exchanger is working, the heat exchange tubes 11 mainly play a role of heat exchange. The plurality of heat exchange tubes 11 are arranged along the length direction of the first collecting member, and the plurality of heat exchange tubes 11 are arranged along the length direction of the second collecting member. The heat exchange tubes 11 are connected to the first collecting member and the second collecting member on both sides of the length direction. In some embodiments, the main body 1 also includes a baffle 12 and a plurality of fins (not shown). Generally, the baffle is not provided with a chamber, so the strength of the baffle is greater than the strength of the heat exchange tube. The baffle is located on one side of the main body 1 and is used to protect the heat exchange tube 11. Optionally, the heat exchanger includes two baffles 12, such as Figure 1 As shown, along the length direction of the first current collecting member or the second current collecting member, the two baffles 12 are respectively located on different sides of the main body 1 and are located between the first current collecting member and the second current collecting member. In some embodiments, the two baffles 12 together with the first current collecting member and the second current collecting member form a square frame, and a plurality of heat exchange tubes 11 are evenly arranged in the frame. A plurality of fins are located between each two adjacent heat exchange tubes 11 to enhance heat exchange. Depending on the performance requirements of the heat exchanger, the number of fins may also be different, and the location of the fins in the main body 1 may also be different. Of course, fins may not be provided in the main body 1 of some heat exchangers, or fins may be provided on the entire main body 1.

[0028] like Figures 3 to 12 The first current collecting part in one embodiment of the present application is shown. The first current collecting part includes a first component 2, a second component 3 and a first seal 4. The first component 2 is connected to the second component 3, and the second component 3 is connected to a plurality of heat exchange tubes 11. Specifically, the second component 3 is connected to one side of the heat exchange tube 11 in the longitudinal direction, and the first component 2 and the second component 3 are matched together. The first seal 4 is located between the first component 2 and the second component 3 and plays a sealing role. The first current collecting part has a first collecting cavity 20, and the first collecting cavity 20 is located between the first component 2 and the second component 3. The first seal 4 is arranged in the second component 3, and the first component 2 abuts against the first seal 4, so that the first seal 4 seals the first collecting cavity 20 to prevent fluid from leaking or overflowing the first collecting cavity 20. The first component 2 includes an inlet component 28, which is used to connect to the piping component in the heat exchange system. The chamber of the inlet component 28 is connected to the first manifold 20 and to the chamber of the piping component. When the heat exchanger is working, the fluid flows from the chamber of the piping component through the chamber of the inlet component 28 into the first manifold 20.

[0029] Optional, such as Figure 2As shown, the first component 2 is an arcuate shell, including a first manifold wall 25. One side of the first manifold wall 25 has a rectangular opening in the height direction. Accordingly, the second component 3 is a rectangular body, adapted to connect with the first component 2. Optionally, the first component 2 can be made of plastic, and the second component 3 can be made of aluminum alloy. This material selection can save costs while meeting the performance requirements of the heat exchanger; it also reduces the weight of the heat exchanger.

[0030] Optionally, the first sealing member 4 is a square sealing ring to match the shapes of the first component 2 and the second component 3. The first sealing member 4 before compression is cylindrical, i.e., the cross-section of the first sealing member 4 before compression is circular. This first sealing member 4 has the advantages of easy processing, high processing precision, and good sealing effect. Optionally, the first sealing member 4 is made of EPDM rubber.

[0031] Figure 1 and Figure 2 The second collecting part in one embodiment of the present application is shown, and the second collecting part includes a third component 5, a fourth component 7 and a second sealing component 6. The third component 5 is connected to the fourth component 7, and the fourth component 7 is connected to a plurality of heat exchange tubes 11. The second sealing component 6 is located between the third component 5 and the fourth component 7. The heat exchanger has a second collecting chamber 50, and the second collecting chamber 50 is located between the third component 5 and the fourth component 7. The second sealing component 6 is arranged in the fourth component 7, and the third component 5 abuts against the second sealing component 6, so that the second sealing component 6 plays a sealing role to prevent liquid from overflowing from the second collecting chamber 50. The third component 5 includes an outlet component 51, and the outlet component 51 is connected to the piping component in the heat exchange system. The chamber of the outlet component 51 is connected to the second collecting chamber 50. When the heat exchanger is working, the fluid flows from the second collecting chamber 50 through the chamber of the outlet component 51 to the chamber of the piping component. Optionally, as Figure 2 As shown, the third component 5 is an arcuate shell, with one side of the third component 5 in the height direction being a rectangular body. Accordingly, the fourth component 7 is a rectangular body, adapted to be connected to the third component 5. The height direction of the third component 5 coincides with or is parallel to the length direction of the heat exchange tube 11. Optionally, the third component 5 is made of plastic, and the fourth component 7 is made of aluminum alloy. These material choices can save costs while meeting the performance requirements of the heat exchanger and have the advantage of reducing the weight of the heat exchanger.

[0032] In one embodiment of the present application, the first collecting member and the second collecting member are respectively located on different sides of the main body 1, that is, the first collecting member and the second collecting member are respectively located on different sides of the length direction of the heat exchange tube 11. For the convenience of processing, the first collecting member and the second collecting member have the same structure. It is understandable that the above-mentioned first collecting member can also be a liquid outflow member, and the second collecting member can also be a liquid outflow member. That is, one of the first collecting member and the second collecting member is a liquid inflow member, and the other is a liquid outflow member. It is understandable that the structures of the first collecting member and the second collecting member can also be different. Specifically, the positional relationship and structural characteristics of the first collecting member and the second collecting member are set according to the installation position, use requirements, processing technology requirements, etc. of the heat exchanger. It is understandable that in some other embodiments, the first collecting member and the second collecting member can also be located on the same side of the main body 1. In this case, the flow path of the heat exchanger can be two-flow or multi-flow.

[0033] In one embodiment of the present application, the heat exchanger is a single-flow heat exchanger, and the specific flow path is as follows: the liquid enters the first manifold 20 from the chamber of the inlet component 28, and is distributed from the first manifold 20 to a plurality of heat exchange tubes 11. After the heat exchange action of the heat exchange tubes 11, it flows to the second manifold 50 and flows out from the chamber of the outlet component 51, thereby completing a circulation cycle.

[0034] Figures 3 to 12 The connecting structure between the first component 2 and the second component 3 in one embodiment of the present application is shown, and the connecting structure includes a positioning structure and a buckling structure 32.

[0035] The positioning structure is used to locate the position between the first component 2 and the second component 3, particularly the position of the first component 2 and the second component 3 along the length of the heat exchange tube 11. This positioning structure can position the first component 2 and the second component 3 at a preset position, so that the compression of the first seal 4 is within a preset range, improving the sealing effect of the first seal 4 and extending the service life of the first seal 4. This positioning structure can effectively prevent defects such as the first seal 4 being compressed too little, not compressed enough, or compressed too much. The snap-fit ​​structure 32 is used to secure the first component 2 and the second component 3, so that the first component 2 and the second component 3 snap together to form the first manifold 20.

[0036] Optionally, the first current collecting part includes a plurality of positioning structures, which are located on both sides of the length direction of the first current collecting part, and the plurality of positioning structures are spaced apart and evenly distributed. The snap-fit ​​structure 32 is located around the first current collecting part, that is, the snap-fit ​​structure 32 surrounds the first current collecting part circumferentially and is located at the connection between the first component 2 and the second component 3. Optionally, the snap-fit ​​structures 32 are spaced apart from each other and evenly distributed around the first current collecting part. Optionally, along the length direction of the first current collecting part, the positioning structures and the snap-fit ​​structures 32 on each side of the width direction of the first current collecting part are spaced apart from each other.

[0037] Figures 3 to 10 The first component 2 in one embodiment of the present application is shown, and the first component 2 also includes a first protrusion 21. The first manifold wall 25 surrounds the first manifold 20, and the first manifold 20 is located between the first manifold wall 25 and the second component 3. The first protrusion 21 is connected to the first manifold wall 25. The first protrusion 21 is located on one side of the first manifold wall 25 in the height direction, and the height direction of the first manifold wall 25 coincides with or is parallel to the length direction of the heat exchange tube 11. Specifically, the first manifold wall 25 is an arc-shaped shell, one side of the first manifold wall 25 in the height direction is connected to the first protrusion 21, and the other side of the first manifold wall 25 in the height direction is connected to the inlet component 28. One side of the first manifold wall 25 in the height direction faces the main body 1, and the inlet component 28 and the main body 1 are respectively located on different sides of the first manifold wall 25. The inlet component 28 and the first protrusion 21 are respectively located on different sides of the first manifold wall 25.

[0038] The first protrusion 21 circumferentially surrounds the first manifold wall 25 and protrudes from the outer wall of the first manifold wall 25 away from the first manifold 20 along the width of the first manifold wall 25. The width of the first manifold wall 25 coincides with or is parallel to the width of the first component 2. The height of the first manifold wall 25 coincides with or is parallel to the length of the heat exchange tubes 11. The length of the first manifold wall 25 is parallel to or coincides with the length of the first component. The width of the first manifold wall 25 is perpendicular to the length of the first manifold wall 25 and perpendicular to the height of the first manifold wall 25. It is understood that the first protrusion 21 may also protrude away from the first manifold 20 at a slight upward or downward angle along the width of the first manifold wall 25.

[0039] Optionally, the first protrusion 21 is in the form of a square annular boss. The protrusion's width, relative to the outer surface of the first manifold wall 25, extending from the first manifold wall 25 away from the first manifold 20 is approximately equal. This protrusion width is the distance from the outer surface of the first manifold wall 25 away from the first manifold 20. Along the length of the heat exchange tube 11, the first protrusion 21 has a certain thickness to effectively resist the snap-fit ​​pressure of the second component 3 and the impact force of the fluid on the connection between the first and second components 2 and 3 during operation of the heat exchanger. The thickness of the first protrusion 21 is set based on parameters such as the structural dimensions of the second component 3 and the first component 2, and the operating environment of the heat exchanger.

[0040] The second component 3 includes a first wall 31, which serves as its circumferential wall. The first wall 31 extends along the length of the heat exchange tube 11, with portions of the first wall 31 bent toward the first protrusion 21. The first wall 31 includes a plurality of snap-fit ​​structures 32, which are the portions of the first wall 31 that bend toward the first protrusion 21. The snap-fit ​​structures 32 engage with the first protrusion 21 to securely connect the first component 2 to the second component 3.

[0041] The buckle structure 32 is in the shape of a bent plate, which is bent toward the first protruding portion 21 and matched with the first protruding portion 21. Specifically, Figure 12 As shown, the buckling structure 32 is a square flat plate before being bent. The buckling structure 32 is bent toward the first protrusion 21 and is in the shape of a bent plate for buckling on the first protrusion 21. Multiple buckling structures 32 are arranged at intervals and distributed around the first wall 31.

[0042] Optionally, the multiple snap-fit ​​structures 32 are evenly distributed around the first wall 31. The snap-fit ​​structures 32 are equal in number on both sides of the width of the second component 3 and are evenly distributed on each of these two sides. The snap-fit ​​structures 32 are equal in number on both sides of the length of the second component 3 and are evenly distributed on each of these two sides. The height of the second component 3 coincides with or is parallel to the length of the heat exchange tube 11. The width of the second component 3 is perpendicular to the length of the second component 3 and perpendicular to the height of the second component 3.

[0043] like Figure 4 and Figure 9 As shown, the first protrusion 21 includes a third step surface 211 and a fourth step surface 212, and the third step surface 211 and the fourth step surface 212 are respectively located on different sides of the thickness direction of the first protrusion 21. The third step surface 211 is away from the main body 1, and the fourth step surface 212 faces the main body 1. The inner wall surface of part or all of the buckling structure 32 cooperates with part or all of the third step surface 211. Optionally, the inner wall surface of part or all of the buckling structure 32 is in contact with part or all of the third step surface 211. Optionally, the third step surface 211 surrounds the first manifold wall 25, and the fourth step surface 212 surrounds the first manifold wall 25. Optionally, the third step surface 211 and the fourth step surface 212 are both planes.

[0044] In one embodiment of the present application, multiple positioning structures are located on different sides of the width direction of the first current collecting part. The height direction of the first current collecting part is oppositely coincident or parallel to the length of the heat exchange tube 11. The width direction of the first current collecting part is perpendicular to the length direction of the first current collecting part, and the width direction of the first current collecting part is perpendicular to the height direction of the first current collecting part. Optionally, multiple positioning structures are evenly distributed on both sides of the width direction of the first current collecting part, and the number of positioning structures on both sides of the width direction of the first current collecting part is equal and evenly distributed on the above-mentioned two sides.

[0045] like Figures 3 to 10 As shown, the first component 2 also includes a plurality of second protrusions 22 and a plurality of reinforcing ribs 23. The second protrusions 22 serve as positioning elements. Along the direction of extension of the first protrusion 21, some or all of the second protrusions 22 protrude beyond the first protrusion 21 in a direction away from the first manifold 20, and some or all of the second protrusions 22 abut against the second component 3.

[0046] The reinforcing ribs 23 are used to increase the strength of the first component 2 and can effectively control the deformation amount or deformation direction of the first component 2. Several reinforcing ribs 23 are located on the outer wall surface of the first manifold wall 25 and are connected to the first manifold wall 25. Each reinforcing rib 23 protrudes from the outer wall surface of the first manifold wall 25 in a direction away from the first manifold 20. Along the width direction of the first component 2, each reinforcing rib 23 circumferentially surrounds the first manifold wall 25, that is, each reinforcing rib 23 extends from one side of the first manifold wall 25 in the width direction to the other side of the first manifold wall 25 in the width direction, and the two ends of each reinforcing rib 23 in the extension direction are respectively connected to the first protrusions 21 on both sides of the first manifold wall 25 in the width direction.

[0047] like Figure 3 As shown, the first manifold wall 25 is an arcuate shell, and the reinforcing ribs 23 are arched strips. The ribs 23 are uniform strips, meaning that the cross-sectional dimensions of the ribs 23 are approximately equal from one side to the other along their length. This approximately equal dimension visually indicates a minimal difference in size. Optionally, multiple reinforcing ribs 23 may be evenly spaced along the length of the first component 2.

[0048] Understandably, if Figures 7 to 10 As shown, the second protrusion 22 is located at the end of the extension direction of the reinforcing rib 23. The reinforcing rib 23 is connected to the first protrusion 21, and the reinforcing rib 23 is connected to the third step surface 211. The second protrusion 22 is the portion that continues to extend along the extension direction of the reinforcing rib 23 from the end of the reinforcing rib 23, passes through the third step surface 211, and protrudes from the first protrusion 21.

[0049] It can be understood that the plurality of second protrusions 22 are located on both sides of the width direction of the first manifold wall 25. Since the second protrusions 22 are located at both ends of the extension direction of the reinforcement ribs 23, the number of second protrusions 22 on each side of the width direction of the first manifold wall 25 is equal to the number of second protrusions 22 on the other side. Optionally, the plurality of second protrusions 22 on both sides of the width direction of the first component 2 are evenly spaced. In some embodiments, the second protrusion 22 can be provided at only one end of the extension direction of a reinforcement rib 23, and the second protrusion 22 can be provided at the other end of the extension direction of the adjacent or spaced reinforcement ribs 23, so that the plurality of second protrusions 22 are distributed on both sides of the width direction of the first component 2, so as to effectively realize the positioning between the first component 2 and the second component 3.

[0050] like Figure 9 and Figure 10 As shown, the first protrusion 21 includes a first side surface 213, which is located between the third step surface 211 and the fourth step surface 212. The first side surface 213 is the side of the first protrusion 21 facing away from the first manifold 20. A reinforcing rib 23 is connected to the third step surface 211 and to at least a portion of the first side surface 213. The reinforcing rib 23 protrudes from the first side surface 213 away from the first manifold 20. This protruding portion constitutes part or all of the second protrusion 22. The second protrusion 22 is connected to the third step surface 211 and to the first side surface 213. Specifically, along the width of the first component 2, the second protrusion 22 protrudes from the first side surface 213 away from the first manifold 20. Along the length of the heat exchange tube 11, along the extension direction of the reinforcing rib 23, the second protrusion 22 extends from the end of the reinforcing rib 23 toward the main body 1.

[0051] Since the second protrusion 22 is located at the end of the extension direction of the reinforcing rib 23, the reinforcing rib 23 can also be considered to include the second protrusion 22, and the second protrusion 22 is the end portion of the extension direction of the reinforcing rib 23. Optionally, along the length direction of the first current collecting member, the width of the second protrusion 22 is equal to or approximately equal to the width of the reinforcing rib 23.

[0052] like Figures 3 to 6As shown, the first wall 31 has a positioning groove 33, and the positioning groove 33 is located between every two adjacent snap-fit ​​structures 32. The second protrusion 22 is located in the positioning groove 33. Specifically, the first wall 31 includes a cutout portion, and the positioning groove 33 is the cutout of the cutout portion, and every two adjacent snap-fit ​​structures 32 located on the same side are located on both sides of the cutout portion. The cutout size of the cutout portion is the groove width of the positioning groove 33. The first wall 31 has a positioning portion 34, and the positioning portion 34 is located at the bottom of the positioning groove 33, and the second protrusion 22 abuts against the positioning portion 34. The above-mentioned cutout portion includes two side surfaces and a bottom surface, and the optional above-mentioned positioning portion 34 is the bottom surface. Optionally, the positioning grooves 33 are evenly distributed on both sides in the width direction of the second component 3. The positioning grooves 33 and the second protrusion 22 are arranged accordingly.

[0053] Specifically, the second protrusion 22 includes a second stepped surface 220, which faces the main body 1. The positioning portion 34 includes a first stepped surface 340, which serves as the bottom surface of the aforementioned cutout. Part or all of the second stepped surface 220 mates with part or all of the first stepped surface 340. Optionally, at least part of the second stepped surface 220 mates with at least part of the first stepped surface 340. The positioning structure is the abutment structure between the second protrusion 22 and the positioning portion 34. Optionally, both the first stepped surface 340 and the second stepped surface 220 are planar.

[0054] like Figure 11 and Figure 12 As shown, the first wall 31 includes a second side surface 35, a third side surface 36, and the aforementioned first stepped surface 340. Along the length of the first component 2, the second side surface 35 and the third side surface 36 are located on opposite sides of the positioning groove 33, and both the second side surface 35 and the third side surface 36 are planar. The distance between the second side surface 35 and the third side surface 36 is the groove width, i.e., the size of the cutout portion. Optionally, the width of the reinforcing rib 23 is equal to or approximately equal to the width of the second protrusion 22. The maximum width of the second protrusion 22 is less than the groove width of the positioning groove 33, so that the second protrusion 22 can be located in the positioning groove 33 and abut the positioning portion 34.

[0055] The first seal 4 is located in the groove of the sealing groove 30. The bottom wall 37 is provided with a plurality of mounting holes for inserting a plurality of heat exchange tubes 11 therethrough. Optionally, the outer wall of one side of the heat exchange tube 11 along its length is brazed to the wall of the mounting hole. The sealing groove 30 is located between the first wall 31 and the bottom wall 37. The bottom wall 37 protrudes a predetermined distance along the length of the heat exchange tube 11 toward the first manifold 20, so that the second component 3 forms the sealing groove 30. The first protrusion 21 is partially or entirely located in the sealing groove 30 and is configured to abut against the first seal 4.

[0056] Optionally, the first component 2 is an integral part; the second component 3 is an integral part.

[0057] The second protrusion 22 abuts against the positioning portion 34 in the positioning groove 33 to pre-position the first component 2 and the second component 3, thereby improving the sealing effect of the first seal 4 within the preset deformation range and extending the service life of the first seal 4 to a certain extent.

[0058] The aforementioned snap-fit ​​structure 32 is the bent portion of the first wall 31. After the first component 2 and the second component 3 are positioned, the first wall 31 is bent toward the first component 2, specifically toward the first protrusion 21, by means of an external force. This forms a bent portion on one side of the first wall 31 and snaps onto the first protrusion 21, thereby connecting the first component 2 and the second component 3. Therefore, the pre-positioning of the first component 2 and the second component 3 plays a key role in the amount of compression applied to the first seal 4. When the amount of compression applied by the first component 2 to the first seal 4 is small, the sealing effect is poor, and liquid is likely to overflow from the first manifold 20. When the amount of compression applied by the first component 2 to the first seal 4 is excessive, fatigue failure of the first seal 4 may occur, shortening its service life and thus its sealing effect.
