Description

Technical Field

[0001] This application relates to the field of thermal management technology, and more particularly to a heat exchange component and a powertrain. Background Technology

[0002] In thermal management systems, connecting pipes often serve as passageways for fluid media (such as oil and coolant) and are widely used in heat exchange components with heat exchange chambers. One end of the connecting pipe connects to the inlet or outlet of the heat exchange chamber, while the other end connects to external piping to allow fluid inflow or outflow. These connecting pipes are common in components with heat exchange functions, such as oil coolers and radiators, where they circulate with external oil or water circuits to complete heat exchange.

[0003] Taking oil coolers as an example, the core component of an oil cooler is the heat dissipation core, and the connecting pipes, serving as the inlet and outlet interfaces for oil or coolant, are directly fixed to the core in a predetermined position using welding. Because different application scenarios (such as different vehicle models and different equipment) have different requirements for the installation angle, orientation, and docking position of the connecting pipes, and the angle and position of the connecting pipes are relatively fixed after welding, the versatility of the same oil cooler is poor. To meet the usage requirements of different vehicles for oil coolers, multiple sets of molds need to be developed to produce oil coolers of different specifications, thus increasing production costs.

[0041] In existing thermal management systems, connecting pipes are usually installed on heat exchange components with heat exchange chambers. One end of the connecting pipe is connected to the inlet or outlet of the heat exchange chamber, while the other end is used to connect to external pipelines, so that the heat exchange medium can flow into or out of the heat exchange chamber.

[0042] Taking an oil cooler as an example, its core component is the heat dissipation core. In existing technology, the connecting pipe, serving as the inlet and outlet interface for oil or coolant, is typically fixed directly to the core by welding. However, different vehicle models and equipment have varying requirements for the installation angle and orientation of the connecting pipe on the oil cooler. Once welded to the oil cooler, the angle of the connecting pipe cannot be adjusted, resulting in poor versatility. To meet the diverse needs of different vehicles for oil coolers, multiple sets of molds need to be developed to process oil coolers of different specifications, leading to increased production costs.

[0043] In view of this, embodiments of this application provide a heat exchange component and a power assembly, which will be described below in conjunction with the accompanying drawings.

[0044] Reference Figure 1 and Figure 2 As shown in the figure, the heat exchange component of this application embodiment includes a core 100, at least one connecting seat 200 and at least one connecting pipe 300.

[0045] The core 100 has a heat exchange chamber 110, and at least one interface 120 communicating with the heat exchange chamber 110. The connecting seat 200 has a through connecting channel 210, a first connecting portion 220, and a second connecting portion 130 on the core 100. The first connecting portion 220 and the second connecting portion 130 are connected. The connecting seat 200 rotates relative to the axis of the interface 120, and the connecting channel 210 communicates with the heat exchange chamber 110 through the interface 120. The connecting pipe 300 is correspondingly connected to the connecting seat 200.

[0046] In the heat exchange components and power assembly of this application embodiment, the first connecting portion 220 of the connecting seat 200 is connected to the second connecting portion 130 of the core 100, the connecting pipe 300 is correspondingly connected to the connecting seat 200, and the connecting seat 200 can rotate relative to the axis of the interface 120. The installation angle and orientation of the connecting pipe 300 can be adjusted according to the arrangement requirements, which is beneficial to improve the versatility of the heat exchange components, thereby reducing the investment cost of the molds used to process the heat exchange components, and thus reducing the production cost.

[0047] It should be noted that the heat exchange components in this embodiment may be, for example, oil coolers, radiators, or other heat exchange products that have a heat exchange cavity 110 and need to be connected to an external pipeline via a connecting pipe 300. The structure of the heat exchange component will be described below using an oil cooler as an example.

[0048] The heat exchange chamber 110 inside the core 100 serves as a flow channel for the heat exchange medium. Figure 3 The image only shows the location of the heat exchange chamber 110. For the specific structural form of the heat exchange chamber 110, please refer to the prior art or determine it according to the usage requirements. The interface 120 is tubular and is usually located on one side of the end of the core 100 to facilitate the flow of the heat exchange medium into or out of the core 100 via the connecting pipe 300.

[0049] In some possible implementations, the first connecting portion 220 and the second connecting portion 130 snap together. The connector 200 is mounted on the core 100 by snap-fit, which improves the ease of installation of the connector 200 on the core 100. In addition, while the connector 200 and the core 100 are connected, it also helps to ensure that the connector 200 rotates about the axis of the interface 120, thereby facilitating the adjustment of the installation angle and orientation of the connecting tube 300.

[0050] In this design, one of the first connecting portion 220 and the second connecting portion 130 is a snap-fit ​​221, and the other of the first connecting portion 220 and the second connecting portion 130 is a slot that matches the snap-fit ​​221. The snap-fit ​​structure of the snap-fit ​​221 and the slot facilitates snap-fit ​​and provides good connection reliability.

[0051] In this embodiment, there are at least two latches 221, which are spaced apart circumferentially around one of the interface 120 and the connecting seat 200. The slot is an annular groove circumferentially around the other of the interface 120 and the connecting seat 200. The slot is designed as an annular groove so that when the connecting seat 200 rotates 360° around the axis of the interface 120, the latches 221 rotate within the slot and remain engaged with it.

[0052] During the installation of the connecting pipe 300, the installation angle and orientation of the connecting pipe 300 can be set according to the installation requirements, and then the connecting seat 200 is rotated. In addition, at least two clips 221 engage with the slots, which helps to improve the reliability of the engagement and the stability of the connecting seat 200 during rotation.

[0053] In some possible implementations, such as Figure 2 , Figure 4 and Figure 5 As shown, the latch 221 is disposed at the end of the connector 200 facing the core 100, and there are four latches 221 spaced circumferentially around the connector channel 210. The slot is located on the side of the interface 120 facing the heat exchange chamber 110, and the axis of the slot is collinear with the axis of the interface 120.

[0054] The connector 200's latches 221 are inserted into the interface 120. By engaging the four latches 221 with the slots, the connector 200 can be installed on the core 100, ensuring that the connector 200 can rotate relative to the axis of the interface 120. In the engaged state, the end face of the connector 200 facing the core 100 abuts against the corresponding face of the core 100, which also helps improve the stability of the connector 200 during rotation.

[0055] Understandably, the number of clips 221 can be adjusted according to usage requirements. To ensure the effectiveness of the snap-fit, the minimum number of clips 221 should be two.

[0056] The heat exchange component in this embodiment further includes a first seal 400, which is disposed between the connecting seat 200 and the core 100 to seal the gap between them. By providing the first seal 400, leakage at the connection between the connecting seat 200 and the interface 120 is prevented, thereby ensuring the performance of the heat exchange component.

[0057] An exemplary arrangement of the first seal 400 is shown in reference to Figure 2 As shown, a slot 240 is provided on the side of the connector 200 facing the core 100, and the interface 120 is inserted into the slot 240. A gap is formed between the inner wall of the slot 240 and the outer wall of the interface 120. The first seal 400 is specifically provided between the inner wall of the slot 240 and the outer wall of the interface 120 to close the gap.

[0058] In specific implementation, the first sealing element 400 can be a sealing ring, and a first mounting groove for installing the first sealing element 400 is provided on the outer wall of the interface 120. After the connecting seat 200 and the core 100 are engaged, the first sealing element 400 achieves a seal between the connecting seat 200 and the core 100. Of course, the first mounting groove can also be provided on the connecting seat 200, in which case the first sealing element 400 is installed on the connecting seat 200.

[0059] In addition, to facilitate the rotation of the connecting seat 200, multiple friction protrusions can be provided on the outer wall surface of the connecting seat 200, with the multiple friction protrusions spaced apart around the circumference of the connecting seat 200. Alternatively, the cross-section of the connecting seat 200 can be made polygonal, such as a pentagon or a regular hexagon, which also facilitates the rotation of the connecting seat 200.

[0060] In some possible implementations, one of the connecting pipe 300 and the connecting seat 200 is provided with a third connecting portion 310, and the other of the connecting pipe 300 and the connecting seat 200 is provided with a fourth connecting portion 230. The third connecting portion 310 and the fourth connecting portion 230 are detachably connected. This detachable connection of the third connecting portion 310 and the fourth connecting portion 230 facilitates the removal of the connecting pipe 300 from the connecting seat 200. Compared to the prior art where the connecting pipe 300 is directly welded to the core 100, this facilitates the replacement and maintenance of the connecting pipe 300.

[0061] For example, if the connecting pipe 300 is damaged, only the connecting pipe 300 needs to be replaced, which helps reduce maintenance costs. Furthermore, different specifications of connecting pipes 300 can be connected to the connecting seat 200 according to different usage requirements, which also helps improve the versatility and flexibility of the heat exchange components.

[0062] like Figures 4 to 6 As shown, the third connecting part 310 is an external threaded section, and the fourth connecting part 230 is an internal threaded section that is screwed onto the external threaded section. Here, the connection between the external threaded section and the internal threaded section allows the connecting pipe 300 to be installed on the connecting seat 200, and the installation and removal of the connecting pipe 300 on the connecting seat 200 are both relatively convenient.

[0063] As a structural example, such as Figure 6 As shown, the end of the connecting pipe 300 has a first section and a second section 330 connected together. The second section 330 is located outside the first section, and an external thread section is provided on the first section. An internal thread section is provided at the end of the connecting channel 210 facing the connecting pipe 300. As the second section 330 is inserted into the connecting channel 210, rotating the connecting seat 200 allows the internal thread section and the external thread section to be screwed together.

[0064] In this embodiment, the snap fastener 221 can be an elastic snap fastener. The snap fastener 221 has an initial state oriented towards the axis of the connecting seat 200, and a snap-fit ​​state connected to the slot. In the initial state, the snap fastener 221 faces the axis of the connecting seat 200, facilitating its insertion into the interface 120 for engagement with the slot. During the rotation of the connecting seat 200, the second segment 330 of the connecting tube 300 extends out of the connecting channel 210 and inserts into the heat exchange chamber 110. The second segment 330 inserts into the space defined between the multiple snap fasteners 221 and radially pushes each snap fastener 221, causing them to flip towards the slot until they are engaged, thereby mounting the connecting seat 200 onto the core 100.

[0065] In the latched state, the second segment 330 abuts against the side of each latch 221 facing away from the slot, thereby ensuring that the latch 221 and the slot remain latched. The second segment 330 is configured to drive the latch 221 from the initial state to the latched state.

[0066] When it is necessary to disassemble the connector 200, rotate the connector 200 in the reverse direction, causing the connecting tube 300 to move outward. When the second section 330 releases its contact with each clip 221, each clip 221 will disengage from the slot due to its own elasticity, returning to its initial state. At this point, the connector 200 can be removed from the core 100. Here, the second section 330 not only facilitates the engagement of the clips 221 with the slots but also facilitates the release of the engagement, making it easy to disassemble and replace the connector 200.

[0067] In some possible implementations, one of the connecting pipe 300 and the connecting seat 200 is provided with a radially protruding limiting portion 320, which is used to limit the displacement of the connecting pipe 300 along the axial direction of the connecting seat 200. The provision of the limiting portion 320 here helps to ensure that the connecting pipe 300 is installed in place on the connecting seat 200, at which point it is not necessary to continue rotating the connecting seat 200.

[0068] For example, the limiting part 320 can be provided on the connecting tube 300. During the rotation of the connecting seat 200, when the limiting part 320 abuts against the end of the connecting seat 200 away from the core 100, it indicates that the connecting tube 300 is installed in place on the connecting seat 200, and there is no need to continue rotating the connecting seat 200 at this time.

[0069] like Figure 2 and Figure 6 As shown, the limiting part 320 is provided at the end of the first segment away from the second segment 330. The limiting part 320 is an annular protrusion provided along the circumference of the connecting pipe 300. The limiting part 320 abuts against the connecting seat 200 and restricts the axial displacement of the connecting pipe 300 into the connecting seat 200.

[0070] In this embodiment, the limiting part 320 is an annular protrusion, which increases the contact area between the limiting part 320 and the connecting seat 200, thereby improving the limiting stability of the limiting part. In addition to being an annular protrusion, the limiting part 320 can also be at least two protrusions spaced apart circumferentially along the connecting pipe 300. In this case, the abutment between the protrusion and the connecting seat 200 can also achieve the purpose of limiting.

[0071] In some possible implementations, the heat exchange component further includes a second seal 500, which is disposed between the connecting seat 200 and the connecting pipe 300 to seal the gap between them. The second seal 500 improves the sealing effect between the connecting seat 200 and the connecting pipe 300, preventing leakage at the connection point and thus ensuring the performance of the heat exchange component.

[0072] like Figure 2As shown, the second seal 500 is a sealing ring. A radial gap is formed between the outer wall of the connecting pipe 300 and the inner wall of the connecting channel 210. The second seal 500 is used to seal this radial gap. Specifically, a second mounting groove is provided on the outer wall of the end of the second segment 330 that connects to the first segment. The second mounting groove is arranged circumferentially around the second segment 330, and the second seal 500 is installed in the second mounting groove. When the connecting pipe 300 and the connecting seat 200 are in the connected state, the second seal 500 is located between the outer wall of the connecting pipe 300 and the inner wall of the connecting channel 210, thereby facilitating the sealing of the connection between the connecting pipe 300 and the connecting seat 200.

[0073] In this embodiment, both the first seal 400 and the second seal 500 are used to seal the radial gap. Compared with the traditional solution of setting a seal between the end faces of two components, this reduces the precision requirements of the sealing surface, thereby reducing the processing difficulty and production cost, and has a better sealing effect.

[0074] In this embodiment, the connecting pipe 300 can be a plastic pipe. Compared to traditional metal pipes, plastic pipes facilitate the weight reduction of heat exchange components. For example, the connecting pipe 300 can be made of nylon. Nylon pipes have high tensile strength, bending strength, and impact toughness, and can withstand certain axial forces, radial pressures, and external impacts, thereby improving the performance of the connecting pipe 300. In addition, compared to metal pipes, nylon pipes have a lower elastic modulus, which has a certain absorption effect on the vibration and noise generated by fluid flow, thus reducing the noise generated by the flow.

[0075] In some possible implementations, such as Figure 1 As shown, the heat exchange component also includes a tube body 600. The core 100 has two ports 120, one for the inflow of heat exchange medium and the other for the outflow of heat exchange medium. One of the two ports 120 is connected to a connecting seat 200, on which a connecting pipe 300 is connected. The other of the two ports 120 is connected to the tube body 600. The tube body 600 can be welded to the core 100. In this case, the installation angle and orientation of the connecting pipe 300 of the heat exchange component are adjustable, while the installation angle and orientation of the tube body 600 are not adjustable.

[0076] In some possible implementations, the core 100 has two interfaces 120, with a connecting seat 200 and a connecting pipe 300 corresponding to each interface 120. In this case, each connecting pipe 300 is mounted on a connecting seat 200, and each connecting seat 200 is connected to its corresponding interface 120. The installation angle and orientation of the two connecting pipes 300 on the heat exchange component can be adjusted, which helps to further improve the versatility of the heat exchange component.

[0077] In some possible implementations, the number of interfaces 120 may be greater than two, with at least one interface 120 connected to a connector 200, and a connector 300 connected to the connector 200. This also improves the versatility of the heat exchange components compared to the prior art where the connector 300 is welded to the core 100.

[0078] In this embodiment, the heat exchange component is connected to the core 100 via a connecting seat 200, and the connecting pipe 300 is connected to the connecting seat 200, allowing the connecting pipe 300 to rotate around the axis of the interface 120. This facilitates the adjustment of the installation angle and orientation of the connecting pipe 300, thereby improving the versatility of the same model of heat exchange component and reducing the investment in producing heat exchange component processing molds, thus reducing production costs.

[0079] In this embodiment of the application, when installing the connector 200 and the connector 300, first insert the buckle 221 of the connector 200 into the interface 120; then adjust the installation angle and orientation of the connector 300 into place, and insert the second section 330 of the connector 300 into the connection channel 210; then rotate the connector 200, keeping the installation angle and orientation of the connector 300 unchanged during the process.

[0080] As the second section 330 of the connecting pipe 300 extends into the heat exchange chamber 110, the buckle 221 is radially pushed by the second section 330 and locked into the slot, thereby connecting the connecting seat 200 to the core 100. Continue to rotate the connecting seat 200 until the limiting part 320 abuts against the connecting seat 200, indicating that the connecting pipe 300 is installed in place.

[0081] The powertrain of this application embodiment includes a drive motor, an electric drive reducer connected to the drive motor, and an oil cooler. The oil cooler is connected to at least one of the drive motor and the electric drive reducer, and the oil cooler is the heat exchange component described above.

[0082] In some possible implementations, the powertrain can be configured on new energy vehicles, with the oil cooler connected to the cooling channels on both the drive motor and the electric drive reducer to cool the drive motor and the electric drive reducer, thereby preventing the drive motor and the electric drive reducer from malfunctioning due to overheating and ensuring the performance of the drive motor and the electric drive reducer.

[0083] In some possible implementations, the oil cooler is connected to the cooling channel of one of the drive motor and the electric drive reducer to cool the drive motor or the electric drive reducer separately, which also helps to improve the cooling effect.

[0084] The powertrain of this application embodiment uses an oil cooler as the heat exchange component, which facilitates the arrangement and installation of the oil cooler on different vehicle models, thereby facilitating the platformization of the oil cooler and reducing production costs.

[0085] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein. The specification and embodiments are to be considered exemplary only.

[0086] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope.
