Description

Technical Field

[0001] This utility model relates to the field of heat exchange component technology, and more specifically, to a heat exchange component and a vehicle heat exchange system. Background Technology

[0002] In related technologies, heat exchangers often face limitations in connection space when using multi-row configurations, which makes it difficult to achieve an ideal layout and connection when connecting two flow paths.

[0003] Currently, the main connection method between two rows of heat exchangers uses an adapter, aluminum tubes, and another adapter. The two adapters are welded to and connected to the manifolds of the heat exchangers, and then connected via aluminum tubes to achieve connection between the two rows of heat exchangers. This connection method requires independent design and assembly of the adapters and aluminum tubes, resulting in high processing and installation costs. Furthermore, to achieve the connection between the adapters, the aluminum tubes typically need to be long and bent, which further increases design costs and may lead to a larger footprint, hindering the lightweighting and installation of the heat exchange components. Utility Model Content

[0004] This invention provides a heat exchange component and a vehicle heat exchange system to solve the problem of difficult layout and weight reduction when multiple rows of heat exchangers are connected in the related technology.

[0005] To achieve the above objectives, according to one aspect of the present invention, a heat exchange assembly is provided, comprising a heat exchanger and a drying bottle. At least two heat exchangers are stacked together, each heat exchanger is connected to at least one drying bottle, and each drying bottle is connected to at least two heat exchangers. Multiple heat exchangers are connected to each other through the drying bottles. The drying bottle includes a bottle body and a pin structure integrally formed on the periphery of the bottle body. The bottle body is disposed on at least one heat exchanger and connected to the heat exchanger through the pin structure.

[0006] Furthermore, any two adjacent heat exchangers are connected through a drying bottle, and multiple heat exchangers are connected sequentially end to end through drying bottles.

[0007] Furthermore, for any drying flask used to connect two heat exchangers, there are at least two pin structures, and the at least two pin structures are respectively connected to and connected to the two heat exchangers.

[0008] Furthermore, the bottle body is a cylindrical structure, and a pin structure is provided on the outer periphery of any end of the bottle body along the axial direction. For the pin structure at any end of the bottle body along the axial direction, the pin structure includes a pin seat and two mutually spaced sub-pins. The two sub-pins are respectively connected to two heat exchangers, and one of the sub-pins is connected to the corresponding heat exchanger to form a first connection position or a second connection position.

[0009] Furthermore, the heat exchanger includes a manifold connected to the drying flask. The end of the sub-pin facing away from the flask body has an arc-shaped surface adapted to the outer periphery of the manifold. The drying flask has a symmetry plane dividing the flask body into two symmetrical parts. The axis of the flask body lies on the symmetry plane. The projection of the pin structure located at one end of the flask body along the axial direction onto the symmetry plane is the first projection, and the projection of the pin structure located at the other end of the flask body along the axial direction onto the symmetry plane is the second projection. The first and second projections coincide. Multiple pin structures of the drying flask are located on the same side of the flask body and are parallel to each other. The centers of the projections of the arc-shaped surfaces of two sub-pins located at the same end of the flask body along the axial direction onto the symmetry plane are respectively the first circle... The first and second center are defined by the distance X1 between them in the direction perpendicular to the plane of symmetry, where 38mm ≥ X1 ≥ 20mm; the radius of the arc surface is R1, where 50mm ≥ R1 ≥ 20mm; the outer perimeter of the bottle includes an arc surface and a plane, with the radius of the arc surface being R2, where 60mm ≥ R2 ≥ 30mm; the center of the projection of the arc surface onto the plane of symmetry is the third center, and the distance between the third center and the first or second center in the direction parallel to the plane of symmetry is X2, where 55mm ≥ X2 ≥ 37mm; the width of the projection of any sub-pin onto the plane of symmetry is X3, where 35mm ≥ X3 ≥ 15mm.

[0010] Furthermore, the bottle body has a cylindrical structure, and a pin structure is provided on the outer periphery of any end of the bottle body in the axial direction. For the pin structure at any end of the bottle body in the axial direction, the pin structure includes a sub-pin, which is connected to both heat exchangers and communicates with one of the heat exchangers.

[0011] Furthermore, the bottle body has a cylindrical structure. The connection position between the pin structure connected to one of the heat exchangers and the heat exchanger is the first connection position, and the connection position between the pin structure connected to the other heat exchanger and the heat exchanger is the second connection position. The first connection position and the second connection position are spaced apart in the axial direction of the drying bottle. The connection position between the pin structure connected to one of the heat exchangers and the bottle body is the third connection position, and the connection position between the pin structure connected to the other heat exchanger and the bottle body is the fourth connection position. The third connection position and the fourth connection position are spaced apart in the axial direction of the drying bottle.

[0012] Furthermore, the drying bottle also includes a connecting pipe that communicates with the bottle body. For any drying bottle used to connect two heat exchangers, the pin structure is connected to one of the heat exchangers and the connecting pipe is connected to the other heat exchanger.

[0013] Furthermore, the bottle body has a cylindrical structure. The connection position between the pin structure connected to one of the heat exchangers and the heat exchanger is the fifth connection position. The connection position between the connecting pipe connected to the other heat exchanger and the heat exchanger is the sixth connection position. The fifth and sixth connection positions are spaced apart axially on the drying bottle. The connection position between the pin structure connected to one of the heat exchangers and the bottle body is the seventh connection position. The connection position between the connecting pipe connected to the other heat exchanger and the bottle body is the eighth connection position. The seventh and eighth connection positions are spaced apart axially on the drying bottle.

[0014] Furthermore, the drying bottle also includes a transfer tube, which is disposed on the pin structure that communicates with the heat exchanger. The transfer tube is disposed on the side of the pin structure away from the bottle body and extends into the heat exchanger. The cavity of the pin structure is connected to the cavity of the heat exchanger through the transfer tube.

[0015] Furthermore, the heat exchanger includes two manifolds and multiple heat exchange flat tubes arranged side by side between the two manifolds. Both ends of any one heat exchange flat tube are connected to the two manifolds respectively. The side of the pin structure facing away from the bottle body is adapted to the outer periphery of the manifold, and the side of the pin structure facing away from the bottle body is attached to and fixedly connected to the outer periphery of the manifold. Part of the pin structure is connected to the manifold.

[0016] Furthermore, a drying element is provided inside the cavity of the drying bottle, which is used to dry the fluid flowing through the cavity of the drying bottle.

[0017] According to another aspect of the present invention, a vehicle heat exchange system is provided, which includes the aforementioned heat exchange components.

[0018] The present invention provides a heat exchange assembly comprising a heat exchanger and a drying bottle. At least two heat exchangers are stacked together, each heat exchanger is connected to at least one drying bottle, and each drying bottle is connected to at least two heat exchangers. Multiple heat exchangers are connected to each other through the drying bottles. The drying bottle comprises a bottle body and a pin structure integrally formed on the periphery of the bottle body. The bottle body is mounted on at least one heat exchanger and connected to the heat exchanger through the pin structure.

[0019] Compared to the existing technology that uses an adapter and aluminum tube assembly, this solution integrates connectivity into a single structure through a one-piece pin structure and bottle body. This reduces cost and manufacturing complexity while maintaining the reliability and functionality of the dryer bottle. Furthermore, it eliminates the need for designing and installing bent aluminum tubes, avoiding issues such as high design and assembly costs or large footprints in the assembled structure that hinder the lightweighting and installation of heat exchange components. On the other hand, compared to the adapter and aluminum tube assembly in existing technologies, this design provides the dryer bottle with better structural strength. It avoids the connection instability issues that can occur with assembled adapters and aluminum tubes due to vibration or vibration during use, enhancing the overall structural strength of the dryer bottle. It also avoids potential leakage points caused by welding or bonding when the pin structure is separately connected to the bottle body, improving the dryer bottle's sealing performance.

[0036] The technical solutions in at least one embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. The following description of at least one embodiment is merely illustrative and is not intended to limit this application or its applications. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the scope of protection of this application.

[0037] like Figures 1 to 12 As shown, an embodiment of the present invention provides a heat exchange assembly, which includes a heat exchanger 10 and a drying bottle 20. At least two heat exchangers 10 are stacked, and each heat exchanger 10 is connected to at least one drying bottle 20. Each drying bottle 20 is connected to at least two heat exchangers 10, and multiple heat exchangers 10 are connected to each other through the drying bottles 20. The drying bottle 20 includes a bottle body 22 and a pin structure 23 integrally formed on the outer periphery of the bottle body 22. The bottle body 22 is disposed on at least one heat exchanger 10 and connected to the heat exchanger 10 through the pin structure 23.

[0038] Compared to the structure assembled from an adapter and aluminum tube in related technologies, this embodiment integrates the communication function into a single structure through the integrated pin structure 23 and bottle body 22. This reduces both cost and manufacturing difficulty while ensuring the reliability and functionality of the drying bottle 20. Furthermore, it eliminates the need for designing and installing bent aluminum tubes, avoiding issues such as high design and assembly costs or large footprints in the assembled structure, which hinder the lightweighting and installation of heat exchange components. On the other hand, compared to the adapter and aluminum tube assembled later in related technologies, this design provides the drying bottle 20 with better structural strength. It avoids the problem of unreliable connections due to vibration or vibration during use, enhancing the overall structural strength of the drying bottle 20. It also avoids potential leakage points caused by welding or bonding when the adapter and aluminum tube are connected separately in related technologies, improving the sealing performance of the drying bottle 20.

[0039] In this embodiment, a drying element 21 is disposed inside the cavity of the drying bottle 20. The drying element 21 is used to dry the fluid flowing through the cavity of the drying bottle 20. The drying bottle 20 enables communication between two rows of heat exchangers 10. The fluid in the heat exchangers 10 flows to the next heat exchanger 10 through the cavity of the drying bottle 20. During the flow, the fluid is dried by passing through the drying element 21 inside the drying bottle 20. This achieves both communication between multiple rows of heat exchangers 10 and drying during the fluid transfer process. Compared to the structure formed by the adapter and aluminum tube used in related technologies, the drying bottle 20 in this embodiment, as the container for the drying element 21, also acts as a connecting element. This achieves functional integration, reduces the need for additional connecting components, and reduces the overall size of the adapter connection structure. This facilitates the lightweighting of the heat exchange components, improves their functionality, and reduces manufacturing costs.

[0040] In some embodiments, any two adjacent heat exchangers 10 are connected through a drying bottle 20, and multiple heat exchangers 10 are connected sequentially end-to-end through drying bottles 20. This arrangement ensures that the fluid can flow continuously and uniformly through all heat exchangers 10, improving the overall efficiency of heat exchange. The drying bottle 20 acts as an intermediary, allowing the fluid to be sufficiently dried before entering the next heat exchanger 10, avoiding excessive humidity from affecting heat exchange performance, simplifying the system structure, reducing fluid flow resistance, and enhancing system stability and maintenance convenience. It should be noted that this arrangement also facilitates the design of a single inlet and single outlet for the entire heat exchange assembly, avoiding the situation where multiple heat exchangers 10 connected through multiple drying bottles 20 form a main body with multiple inlets or outlets, which helps simplify the flow channel design.

[0041] In this embodiment, there are two heat exchangers 10, and the two heat exchangers 10 are connected through a drying bottle 20.

[0042] like Figure 12 As shown, Embodiment Six of this utility model provides a cross-sectional view of a drying bottle 20. The main structural components of the drying bottle 20 in this embodiment (bottle body 22, drying element 21 and pin structure 23) can be adapted and modified with reference to the structure of the drying bottle 20 provided in the embodiment.

[0043] In such Figures 1 to 9 In some of the embodiments shown, for any one of the drying bottles 20 used to connect the two heat exchangers 10, there are at least two pin structures 23, and the at least two pin structures 23 are respectively connected and communicated with the two heat exchangers 10. This arrangement facilitates the connection between the drying bottle 20 and the heat exchanger 10 through the pin structures 23, and makes it easy to design some of the pin structures 23 to communicate with the heat exchanger 10. The pin structures 23 provide a stable extension and a solid connection point for the connection between the bottle body 22 and the heat exchanger 10, which facilitates the assembly of the drying bottle 20 and the heat exchanger 10.

[0044] Among them, in such Figures 1 to 9 In some embodiments shown, the bottle body 22 has a cylindrical structure. The connection position between the pin structure 23 connected to one of the heat exchangers 10 and the heat exchanger 10 is the first connection position. The connection position between the pin structure 23 connected to the other heat exchanger 10 and the heat exchanger 10 is the second connection position. The first connection position and the second connection position are spaced apart in the axial direction of the drying bottle 20. The connection position between the pin structure 23 connected to one of the heat exchangers 10 and the bottle body 22 is the third connection position. The connection position between the pin structure 23 connected to the other heat exchanger 10 and the bottle body 22 is the fourth connection position. The third connection position and the fourth connection position are spaced apart in the axial direction of the drying bottle 20.

[0045] In this embodiment, the first and second connecting positions are axially spaced apart in the drying bottle 20, and the third and fourth connecting positions are also axially spaced apart in the drying bottle 20. This axially spaced design of the connecting positions helps to maximize the path of the fluid inside the drying bottle 20, ensuring the drying effect. Preferably, the distance between the first and second connecting positions and the distance between the third and fourth connecting positions should be sufficient to ensure the flow length of the fluid inside the drying bottle 20 and the drying effect. This avoids situations where the axial distance between the first and second connecting positions, and between the third and fourth connecting positions in the drying bottle 20, is too small or zero, resulting in most of the fluid entering the drying bottle 20 from the heat exchanger 10 flowing directly out of the drying bottle 20 radially, and the residence time inside the drying bottle 20 being too short, leading to insufficient drying or incomplete drying.

[0046] Specifically, the heat exchanger 10 includes two manifolds 11 and multiple heat exchange flat tubes 12 arranged side-by-side between the two manifolds 11. Both ends of any one heat exchange flat tube 12 are connected to the two manifolds 11 respectively. The side of the pin structure 23 facing away from the bottle body 22 is adapted to the outer periphery of the manifold 11, and the side of the pin structure 23 facing away from the bottle body 22 is attached to and fixedly connected to the outer periphery of the manifold 11. Part of the pin structure 23 is connected to the manifold 11. This arrangement increases the contact area between the pin structure 23 and the manifold 11, which helps ensure relative stability after connection, improving connection effectiveness and installation reliability and stability. The fact that the side of the pin structure 23 facing away from the bottle body 22 is attached to and welded to the outer periphery of the manifold 11 further ensures the reliability and stability of the connection between the drying bottle 20 and the heat exchanger 10.

[0047] It is understandable that the number, distribution, and contact area of ​​the pin structure 23 with the manifold 11 can be adjusted according to the actual situation, as long as the stability of the connection between the drying bottle 20 and the two manifolds 11 can be guaranteed.

[0048] like Figure 1 and Figure 3 In the first embodiment shown, a pin structure 23 is provided on the outer periphery of any end of the bottle body 22 along the axial direction. For each pin structure 23 at any end of the bottle body 22 along the axial direction, the pin structure 23 includes a pin base 231 and two spaced-apart sub-pins 232. The two sub-pins 232 are respectively connected to two heat exchangers 10, and one of the sub-pins 232 is connected to the corresponding heat exchanger 10. This arrangement allows any end of the bottle body 22 to be connected to the manifolds 11 of the two heat exchangers 10 via the two pin structures 23, ensuring the reliability and stability of the connection and improving the connection effect. Furthermore, the end faces of the four sub-pins 232 facing away from the bottle body 22 are adapted to the outer periphery of the corresponding manifold 11, ensuring the contact area between each sub-pin 232 and the manifold 11, further improving the stability and reliability of the installation. The pin socket 231 can be designed or not depending on the actual situation. For example, in some embodiments, the sub-pins 232 can be directly set on the outer periphery of the bottle body 22, or in other embodiments, since it is not necessary to distinguish the spaced sub-pins 232, the pin socket 231 can also be considered as part of the sub-pins 232.

[0049] Specifically, such as Figure 3As shown, the end of the sub-pin 232 facing away from the bottle body 22 has an arc-shaped surface 2301 adapted to the outer periphery of the manifold 11. The drying bottle 20 has a symmetry plane 201 that divides the bottle body 22 into two symmetrical parts. The axis of the bottle body 22 lies on the symmetry plane 201. The projection of the pin structure 23 at one end of the bottle body 22 along the axial direction onto the symmetry plane 201 is the first projection, and the projection of the pin structure 23 at the other end of the bottle body 22 along the axial direction onto the symmetry plane 201 is the second projection. The first projection and the second projection coincide. Multiple pin structures 23 of the drying bottle 20 are located on the same side of the bottle body 22 and are parallel to each other. The projections of the arc-shaped surfaces 2301 of the two sub-pins 232 at the same end of the bottle body 22 along the axial direction onto the symmetry plane 201 are... The centers of the two circles are the first and second centers, respectively, and the distance between the first and second centers in the direction perpendicular to the symmetry plane 201 is X1, 38mm ≥ X1 ≥ 20mm; the radius of the arc surface 2301 is R1, 50mm ≥ R1 ≥ 20mm; the outer periphery of the bottle body 22 includes an arc surface and a plane, the radius of the arc surface is R2, 60mm ≥ R2 ≥ 30mm; the center of the projection of the arc surface onto the symmetry plane 201 is the third center, and the distance between the third center and the first or second center in the direction parallel to the symmetry plane 201 is X2, 55mm ≥ X2 ≥ 37mm; the width of the projection of any sub-pin 232 onto the symmetry plane 201 is X3, 35mm ≥ X3 ≥ 15mm. This configuration, by precisely controlling the size and position of the pin structure 23, ensures a tight fit and stable connection between the drying bottle 20 and the manifold 11, further improving the reliability and stability of the connection. It is understood that in other embodiments, the dimensions of X1 to R2 can be adjusted to accommodate heat exchangers 10 and drying bottles 20 of different specifications, thereby achieving a wider range of applications.

[0050] It is understandable that the pin structure 23 used to connect to the collector 11 can be directly connected to the collector 11 or indirectly connected to the collector 11. Figures 1 to 3 In the first embodiment shown, the pin structure 23 is directly connected to the manifold 11 (that is, the outer periphery of the manifold 11 and the surface of the pin structure 23 that is in contact with the manifold 11 are provided with corresponding connecting holes; after the manifold 11 and the pin structure 23 are installed, their cavities are connected through the connecting holes. A guide limiting structure can also be provided to ensure that the connecting holes of the manifold 11 and the pin structure 23 are installed facing each other, thus ensuring the reliability and stability of fluid flow inside the heat exchange assembly). On the other hand, in... Figure 3 In the first embodiment, the two manifolds 11 on the same side of the two heat exchangers 10 are stacked facing each other in the vertical direction. The pin structures 23 at both ends of the bottle body 22 in the axial direction have the same extension length. In order to increase the convenience of processing, the dimensions of multiple sub-pins 232 can be exactly the same.

[0051] Preferably, the distribution of multiple pin structures 23 of the same drying bottle 20 can be adapted to the actual situation and is not limited to the symmetrical distribution of the connection positions relative to the symmetry plane 201 in this embodiment.

[0052] like Figure 4 and Figure 5 The difference between Embodiment 2 and Embodiment 1 is that the drying bottle 20 in this embodiment further includes an adapter pipe 24. The adapter pipe 24 is disposed on the pin structure 23 communicating with the heat exchanger 10. The adapter pipe 24 is located on the side of the pin structure 23 away from the bottle body 22 and extends into the heat exchanger 10. The cavity of the pin structure 23 is connected to the cavity of the heat exchanger 10 through the adapter pipe 24. This arrangement avoids the situation where, when the two manifolds 11 on the same side of the two heat exchangers 10 are stacked vertically and misaligned, there will be gaps between some pin structures 23 and the corresponding manifolds 11, resulting in communication leakage. At the same time, the adapter pipe 24 ensures the positioning and installation effect of the pin structure 23 and the manifolds 11, improving the reliability and stability of the installation.

[0053] It should be noted that in this embodiment, the positions of the multiple pin structures 23 are symmetrically distributed relative to the symmetry plane 201 to ensure the stability of installation and distribution. However, the symmetrical distribution of the pin structures 23 relative to the symmetry plane 201 is not the same as the symmetrical distribution of the pin structures 23 relative to the symmetry plane 201. That is, the structural dimensions of each pin structure 23 can be adaptively adjusted according to actual conditions. Figures 1 to 3 In the embodiment shown, the lengths of the multiple pin structures 23 used to connect the two heat exchangers 10 are all the same (X2 is the same).

[0054] The adapter tube 24 can be integrally formed with the pin structure 23, or it can be set separately and then fixedly connected. The appropriate option needs to be selected according to the actual situation.

[0055] like Figure 6 and Figure 7 The difference between Embodiment 3 and Embodiment 1 is that the lengths of the two sub-pins 232 used to connect to one of the manifolds 11 are longer than those of the two sub-pins 232 used to connect to the other manifold 11. That is, the relevant limiting parameter X2 for the two sub-pins 232 connected to one manifold 11 is different from the relevant limiting parameter X2 for the two sub-pins 232 connected to the other manifold 11. This arrangement allows the sub-pins 232 to accommodate situations where two manifolds 11 on the same side of the two heat exchangers 10 are stacked in a vertically staggered manner, ensuring the reliability and stability of the close connection between the multiple sub-pins 232 and their corresponding manifolds 11, while also improving the applicability of the drying bottle 20.

[0056] like Figure 8 and Figure 9 The fourth embodiment shown differs from the above embodiments in that a pin structure 23 is provided on the outer periphery of any end of the bottle body 22 in the axial direction. For the pin structure 23 at any end of the bottle body 22 in the axial direction, the pin structure 23 includes a sub-pin 232, which is connected to both heat exchangers 10 and communicates with one of the heat exchangers 10.

[0057] In this embodiment, there is one sub-pin 232, which simultaneously forms two interconnected arc-shaped surfaces 2301 on the side opposite to the bottle body 22, adapted to the outer periphery of the two manifolds 11. Compared to Figures 1 to 3 In Embodiment 1, the two sub-pins 232 on the outer periphery of the same end are spaced apart, which improves the convenience of processing and increases the structural strength of the pin structure 23. At the same time, this arrangement helps to increase the proportion of the actual contact arc of the arc surface 2301 of the pin structure 23 with the current collector 11 to the perimeter of the current collector 11, thereby increasing the contact area between the pin structure 23 and the current collector 11, making it suitable for high-vibration structures and systems.

[0058] In this embodiment, the contact area between a single sub-pin 232 and any one of the current collectors 11 is greater than the contact area between a single sub-pin 232 and the corresponding current collector 11 in Embodiment 1. Preferably, the contact arc between any one sub-pin 232 and one of the current collectors 11 accounts for no less than 20% of the circumferential radius of the current collector 11.

[0059] Preferably, the contact area between the pin structure 23 and the manifold 11 can be increased by increasing the size of the pin structure 23 along the axial direction of the bottle body 22. Both methods can also be used simultaneously, but not all examples are given here.

[0060] like Figure 10 and Figure 11In the fifth embodiment shown, the drying bottle 20 also includes a connecting pipe 25 that communicates with the bottle body 22. For any drying bottle 20 used to connect two heat exchangers 10, the pin structure 23 is connected to one of the heat exchangers 10 and communicates with it, and the connecting pipe 25 is connected to the other heat exchanger 10. In this embodiment, the pin structure 23 is a single sub-pin 232. The drying bottle 20 is fixedly connected to the manifold 11 of one of the heat exchangers 10 through the pin structure 23 and communicates with the manifold 11. The bottle body 22 is connected to the manifold 11 of another heat exchanger 10 through the connecting pipe 25. In this embodiment, the area of ​​the arc-shaped surface 2301 is increased by increasing the axial extension length of the pin structure 23 in the bottle body 22 (in this embodiment, the axial extension length of the pin structure 23 in the bottle body 22 is the same as the axial length of the bottle body 22), which increases the contact area between the pin structure 23 and the manifold 11, making it suitable for high-vibration structures and systems. Furthermore, using the connecting pipe 25 to communicate with the manifold 11 of another heat exchanger 10 instead of the pin structure 23 helps to reduce the overall size of the drying bottle 20 and reduce processing costs. This avoids situations where it is difficult to design or implement the installation and communication due to limited space or the large size of the drying bottle 20, and further improves the applicability of the drying bottle 20. Furthermore, the pin structure 23 connected to one of the heat exchangers 10 is positioned at the fifth connection point, and the connecting pipe 25 connected to the other heat exchanger 10 is positioned at the sixth connection point. The fifth and sixth connection points are axially spaced apart from each other in the drying bottle 20. Similarly, the pin structure 23 connected to one of the heat exchangers 10 is positioned at the seventh connection point, and the connecting pipe 25 connected to the other heat exchanger 10 is positioned at the eighth connection point. The seventh and eighth connection points are axially spaced apart in the drying bottle 20. Preferably, the fifth and sixth connection points are axially spaced apart, and the seventh and eighth connection points are also axially spaced apart. This design of axially spaced connection points helps maximize the fluid path within the drying bottle 20, ensuring a better drying effect. Preferably, the distance between the fifth and sixth connecting positions and the distance between the seventh and eighth connecting positions should be sufficient to ensure the flow length and drying effect of the fluid in the drying bottle 20. This avoids situations where the axial distance between the fifth and sixth connecting positions and the seventh and eighth connecting positions in the drying bottle 20 is too small or zero, in which case most of the fluid entering the drying bottle 20 from the heat exchanger 10 will flow directly out of the drying bottle 20 radially, resulting in a short residence time in the drying bottle 20 that prevents it from being dried or causes incomplete drying.

[0061] It is understood that, in this embodiment, the connection position between the connecting pipe 25 and the bottle body 22 needs to be spaced axially from the connection position between the pin structure 23 and the manifold 11, to ensure that the fluid flowing through the bottle body 22 can flow through the drying element 21 or be dried by the drying element 21 for a sufficient duration. The connecting pipe 25 can be integrally formed with the bottle body 22, or it can be separately installed and then fixedly connected; the appropriate option needs to be selected based on the actual situation.

[0062] Another embodiment of this utility model provides a vehicle heat exchange system, which includes the aforementioned heat exchange components. Compared to the structure formed by assembling an adapter and aluminum tubes in related technologies, this application integrates the communication function into the same structure through an integrated pin structure 23 and bottle body 22. This reduces costs and manufacturing difficulty while ensuring the reliability and functionality of the drying bottle 20. Furthermore, it eliminates the need for designing and installing bent aluminum tubes, avoiding problems such as high design and assembly costs or a large footprint in the assembled structure, which are detrimental to the lightweighting and installation of the heat exchange components.

[0067] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0068] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0069] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application.
