Technical Field

[0001] This invention relates to the field of vehicles, and more specifically to a connecting part and a thermal management component. Background Technology

[0002] Vehicles have a thermal management system, which has many components, complex connections, and occupies a large space. While meeting the functions of the components, the design of connecting parts can integrate some components into a single component, making the thermal management component compact and easy to install. However, the thermal management component has multiple interfaces for connecting to the thermal management system. How to set up the interfaces to make the connection with the system more flexible in order to ensure that there is no interference is a technical problem. Summary of the Invention

[0003] The purpose of this application is to provide a connecting part that can connect components in a thermal management system to form an integrated assembly, while also enabling the interface to be connected to the thermal management system more flexibly.

[0004] To achieve the above objectives, this application adopts the following technical solution: a connecting portion, including a main body, a first transition portion, and a second transition portion. The first transition portion is located at one end of the main body, and the second transition portion is located at the other end of the main body. Both the first and second transition portions are fixedly connected to the main body. The connecting portion has a first flow channel and a second flow channel. The first and second flow channels are not connected inside the connecting portion. The first and second flow channels penetrate the main body. The first flow channel forms a first interface at the first transition portion, and the first flow channel forms a second interface at the second transition portion. The orientation of the first interface can be adjusted by adjusting the position of the first transition portion relative to the main body, and the orientation of the second interface can be adjusted by adjusting the position of the second transition portion relative to the main body.

[0005] A thermal management component includes a liquid storage section, a plate heat exchanger assembly, and a connecting section. The connecting section has an interface and a channel. The interface is able to communicate with the plate heat exchanger assembly and / or the liquid storage section through the channel. The connecting section is the connecting section described above.

[0006] The connecting part of this application is a split structure, including a main body, a first adapter, and a second adapter. The first adapter has a first interface, and the second adapter has a second interface. By adjusting the position of the first adapter and the main body, the orientation of the first interface can be adjusted, and by adjusting the position of the second adapter and the main body, the orientation of the second interface can be adjusted. In this way, the first interface and the second interface can be set to face the corresponding connection end of the system, making the interface more flexibly connected to the thermal management system.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] The connecting portion of this application can be applied to a thermal management component, which can be applied to a vehicle thermal management system. This thermal management system may include a compressor, a condenser, an evaporator, and the thermal management component. (See reference...) Figure 1The thermal management component 1010 includes a liquid storage section 3, a plate heat exchange component 56, and a connecting section 8. It may also include a first valve section 11 and a second valve section 12. The connecting section 8 has an interface and a flow channel. The interface can communicate with the channel inside the plate heat exchange component 56 and / or the liquid storage section 3 through the flow channel. The first valve section 11 and the second valve section 12 can adjust the flow rate, connection, and cut-off of the working medium in the corresponding flow channel. The flow channel includes at least a first flow channel and a second flow channel. The temperature of the working medium flowing through the first flow channel is higher than the temperature of the working medium flowing through the second flow channel. In other words, when the thermal management component is working, there is a temperature difference between the first flow channel and the second flow channel.

[0021] See Figure 1 The plate heat exchanger assembly 56 includes an intermediate heat exchanger 5, a cooler 6, and an internal connecting bridge 506. The internal channels of the cooler 6 include refrigerant channels and coolant channels. The internal channels of the intermediate heat exchanger and the refrigerant channels of the cooler are connected through the internal connecting bridge 506. The working medium in the intermediate heat exchanger is the same, for example, both are refrigerants, but at different temperatures, thus allowing heat exchange within the intermediate heat exchanger. Of course, the plate heat exchanger assembly 56 may also include only the intermediate heat exchanger 5 and the cooler 6, without the internal connecting bridge, in which case the internal channels of the intermediate heat exchanger are directly connected to the refrigerant channels of the cooler.

[0022] See Figure 2 , Figure 3 as well as Figure 4 The connecting part 8 can be a separate structure or a single structure. In this embodiment, the connecting part 8 is a separate structure, and the material of the connecting part can be metal or plastic.

[0023] When the connecting part 8 is a split structure, it includes a main body 81, a first transition part 82, and a second transition part 83. The first transition part 82 is located at one end of the main body 81, and the second transition part 83 is located at the other end of the main body 81. That is, the first transition part 82 and the second transition part 83 are located at different ends of the main body 83, and both the first transition part 82 and the second transition part 83 are fixedly connected to the main body 81. The connecting part 8 also includes a third transition part and a fourth transition part, both of which are fixedly connected to the main body 81. In the above split structure, the material of the main body can be a metal material. When the material of the main body is a metal material, a heat insulation part can be provided as needed to reduce the heat conduction between the first flow channel and the second flow channel.

[0024] See Figure 3 and Figure 4The first adapter portion 82 includes a first body portion 821 and a first connecting portion 822. The first connecting portion 822 protrudes from one side of the first body portion 821 and can extend into the channel of the main body portion 81. The first body portion 821 can abut against the main body portion 81. The connecting portion 8 also includes a first sealing ring 84, which is sleeved on the outer periphery of the first connecting portion 822. The first sealing ring 84 is located between the first connecting portion 822 and the main body portion 81 that forms part of the first flow channel, and can seal the connection between the first adapter portion 82 and the main body portion 81. The first connecting portion 822 has a first through hole 8221, and the main body portion 81 has a first threaded hole 811. The connecting portion includes a first screw (not shown in the figure), which can pass through the first through hole 8221 and be threadedly connected to the main body portion 81 through the first threaded hole 811. The first flow channel 801 has a first interface 10 formed in the first adapter portion 82.

[0025] The second adapter portion 83 includes a second body portion 831 and a second connecting portion 832. The second connecting portion 832 protrudes from the second body portion 831 and can extend into the channel of the main body portion 81. The second body portion 831 can abut against the main body portion 81. The connecting portion 8 includes a second sealing ring 85, which is fitted around the outer periphery of the second connecting portion 832 and is located between the second connecting portion 832 and the main body portion 81 that forms part of the first flow channel. The second connecting portion 832 has a second through hole 8321, and the main body portion 81 has a second threaded hole 812. The connecting portion 8 includes a second screw (not shown in the figure), which passes through the second through hole 8321 and is threadedly connected to the main body portion 81 through the second threaded hole 812. The first flow channel 801 has a second interface 20 formed in the second adapter portion. The second flow channel has a third interface formed at the third transition section, and the third flow channel has a fourth interface formed at the fourth transition section. The third transition section includes a third body section and a third connecting section. The third connecting section protrudes from the third body section and can extend into the channel of the main body section. The third body section can abut against the main body section. The connecting section includes a third sealing ring, which is fitted around the outer periphery of the third connecting section and is located between the third connecting section and the main body section forming part of the second flow channel, thus sealing the connection between the third transition section and the main body section. The fourth transition section includes a fourth body section and a fourth connecting section. The fourth connecting section protrudes from the fourth body section and can extend into the channel of the main body section, thus abutting against the main body section. The connecting section includes a fourth sealing ring, which is fitted around the outer periphery of the fourth connecting section and is located between the fourth connecting section and the main body section forming part of the third flow channel, thus sealing the connection between the fourth transition section and the main body section.

[0026] The first flow channel 801 and the second flow channel 802 in the connecting portion 8 are not connected internally. At least a portion of the axis of the first flow channel 801 and at least a portion of the axis of the second flow channel 802 are arranged parallel to each other. In other words, the first flow channel 801 forms a first interface 10 in the first transition portion 82, and a second interface 20 in the second transition portion 83. The orientation of the first interface 10 can be adjusted by adjusting the position of the first transition portion 82 relative to the main body portion 81, and the orientation of the second interface 20 can be adjusted by adjusting the position of the second transition portion 83 relative to the main body portion 81. This allows the first interface 10 and the second interface 20 to be positioned facing the corresponding connection end of the system, enabling more flexible connection to the thermal management system. (See also...) Figure 1 In this embodiment, both the first interface 10 and the second interface 20 face upwards, facilitating the connection of the thermal management system from the upper part of the thermal management component to the lower part of the thermal management component. Of course, the first interface 10 can also face downwards, forwards, or backwards, and the second interface 20 can also face downwards, forwards, or backwards, matching the interface positions of the thermal management system. In this embodiment, upwards, downwards, forwards, and backwards are defined by… Figure 1 The directions shown are for reference only.

[0027] See Figure 6 The first flow channel 801 includes a first section 8011, a second section 8012, and a third section 8013. The first section 8011 is formed in the main body, the second section 8012 is formed in the first transition section 82, and the third section 8013 is formed in the second transition section 83. The main body 81 has a first mounting hole 841 and a second mounting hole 842. Both the first mounting hole and the second mounting hole are in communication with the first flow channel. A portion of the first valve is located in the first mounting hole, and a portion of the second valve is located in the second mounting hole. The first section 8011 is located between the first mounting hole 841 and the second mounting hole 842. The second section 8012 is located outside the first mounting hole 841, and the third section 8013 is located outside the second mounting hole 842. The connecting section 8 includes a first inlet 30, which is in communication with the first section 8011. The first inlet 30 is located between the first mounting hole 841 and the second mounting hole 842, and is located on the side wall of the connecting section.

[0028] The second segment 8012 includes a first sub-segment 803 and a second sub-segment 804, and the third segment 8013 includes a third sub-segment 805 and a fourth sub-segment 806. The extension direction of the first sub-segment 803 is the same as the extension direction of the first segment 8011, and the extension direction of the third sub-segment 805 is the same as the extension direction of the first segment 8011. The first sub-segment 803 and the second sub-segment 804 are arranged perpendicularly, and the third sub-segment 805 and the fourth sub-segment 806 are arranged perpendicularly. The second sub-segment 804 forms a first interface 10 in the first transition part 82, and the fourth sub-segment 806 forms a second interface 20 in the second transition part 83.

[0029] See Figure 12The first section 8011 of the first flow channel 801 includes a first channel 71 and / or a second channel 72. The first channel 71 communicates with the first mounting hole 841, and the second channel 72 communicates with the second mounting hole 842. The first channel is located on one side of the centerline of the inlet 30, and the second channel is located on the other side of the centerline of the inlet 30, with the centerline of the inlet 30 as the dividing line. The interface of the connecting part includes a first interface 10, a second interface 20, a first inlet 30, a second inlet 8021, and a third outlet 8022. The first interface 10 and the second interface 20 communicate with the first flow channel 801, the second inlet 8021 and the third outlet 8022 communicate with the second flow channel 802, and the first inlet 30 communicates with the first flow channel 801. The connecting part 8 also includes a third mounting hole 843. Figure 1 In one embodiment of the thermal management component, the third mounting hole 843 is connected to the second flow channel, and a sensor is installed through the third mounting hole 843 and connected to the connecting part, which can detect the parameters of the working medium in the second flow channel, such as temperature; in another embodiment of the thermal management component, the third mounting hole is connected to the transition channel, and a sensor is installed through the third mounting hole and connected to the connecting part, which can detect the parameters of the working medium in the transition channel, such as temperature.

[0030] See Figure 12 In this embodiment, when the main body 81 of the connecting portion 8 is made of metal profile, due to the temperature difference between the first flow channel and the second flow channel, a heat insulation portion is provided in the connecting portion to reduce heat conduction between the first flow channel and the second flow channel. The heat insulation portion is located between adjacent first and second flow channels. In this embodiment, the heat insulation portion includes a first heat insulation portion 80, which is located between the first channel 71 and the second flow channel 802. The first heat insulation portion 80 includes a first groove 91 and / or a first hollow portion 92. This heat insulation portion not only reduces heat conduction between the first and second flow channels, but also reduces the weight of the connecting portion and the material cost. Furthermore, this heat insulation portion structure has minimal impact on other functions of the original structure. Of course, the materials of the first, second, third, and fourth transition parts can be the same as those of the main body, or they can be different from those of the main body. For example, the materials of the first, second, third, and fourth transition parts can be injection molded plastic materials.

[0031] See Figure 12The central axis of the second flow channel is parallel to the central axis of the first segment of the first flow channel. The connecting portion 8 has a first spacing portion 90, which separates the second flow channel from the first flow channel by a set distance. The first spacing portion 90 forms part of the wall of the first flow channel and part of the wall of the second flow channel. The first heat insulation portion is located in the first spacing portion 90. The first heat insulation portion includes a first hollow portion 92 and a first groove 91. One opening of the first hollow portion 92 is located at the first end of the connecting portion, and the opening of the first groove 91 is located at the second end of the connecting portion. The first hollow portion 92 and the first groove 91 are connected. The first end and the second end do not intersect. In this embodiment, the non-intersection of the first end and the second end means that the main body of the first end and the main body of the second end are parallel. The parallelism of the main body of the first end and the main body of the second end means that in the actual product, although the first end and the second end may have local depressions or protrusions due to process requirements, the main body is flat and parallel. The first mounting hole and the second mounting hole are located at the first end, the second inlet and the third outlet are located at the second end, the third mounting hole is located on the side wall of the main body, the first interface is located at the first adapter, the second interface is located at the second adapter, and the first inlet is located on the side wall of the main body.

[0032] Combination Figures 8 to 12 Along the circumferential extension direction of the first flow channel, the length L1 of the first hollow portion is less than the length L2 of the first groove, the width of the first hollow portion is equal to the width of the first groove, or in other words, the length L1 of the opening of the first hollow portion is less than the length L2 of the opening of the first groove, the width of the first hollow portion 92 is equal to the width of the first groove 91, and the width of the first heat insulation portion 80 depends on the distance between the first flow channel 801 and the second flow channel 802. The greater the distance between the first flow channel 801 and the second flow channel 802, the greater the width of the first heat insulation portion 80. On one side of the connecting portion, the end 851 of the connecting portion forming the second flow channel protrudes from the end 852 of the connecting portion forming the first flow channel. That is, the connecting portion has a stepped portion on one side, and the ends 851 and 852 of the connecting portion form stepped portions. The end 853 of the connecting portion forming the first groove is aligned with the end 851 of the connecting portion forming the first flow channel. The length of the first groove 91 is greater than the length of the first channel 71 of the first flow channel. The first hollow portion 92 is projected onto the first groove 91. The projection of the first hollow portion is located in the area of ​​the first groove. The first hollow portion is located between the first channel 71 and the second flow channel 802 of the first flow channel. In this way, a first heat insulation part is formed between the first end face and the second end face of the connecting part, which can dissipate heat with the air. At the same time, the heat transfer coefficient of air is lower than that of metal, reducing the heat transfer between the first flow channel and the second flow channel. Meanwhile, the opening formed by the first hollow part on the first end face is smaller than the opening formed by the first groove on the second end face, so that the first end face can be used to arrange the mounting part and other structures, improving the space utilization. Of course, the first hollow part can also be located on the second end face, and the first groove part can be located on the first end face, improving the utilization of the second end face.

[0033] The flow channel also includes a third flow channel, which is arranged parallel to the second channel of the first flow channel. The temperature of the working medium flowing through the second channel of the first flow channel is higher than the temperature of the working medium flowing through the third flow channel. The heat insulation part includes a second heat insulation part, which is located between the third flow channel and the second channel of the first flow channel. The second heat insulation part includes a second groove and / or a second hollow part. Specifically, the opening of the second hollow part is in the same direction as the opening of the first hollow part, that is, the opening of the second hollow part is located at the first end of the connecting part. The opening of the second groove is the same as the opening of the first groove, that is, the second groove is located at the second end of the connecting part. The second hollow part and the second groove are interconnected.

[0034] The inlet is located on the side wall of the connecting part and communicates with the first flow channel. The first hollow part communicates with the second hollow part, and the first groove communicates with the second groove. The total length of the first hollow part and the second hollow part is less than the total length of the first groove and the second groove. The hollow part is projected onto the groove, and the projection of the hollow part is located within the area of ​​the groove. The end of the first flow channel and the end of the second flow channel are aligned on one side of the connecting part, and the other end of the first flow channel and the end of the third flow channel are aligned on the other side of the connecting part. The first mounting hole, the second mounting hole, and the third mounting hole are located at the first end of the connecting part. The connecting part has a first outlet and a second outlet, which are located at the second end of the connecting part. The first outlet communicates with the second flow channel, and the second outlet communicates with the third flow channel. The working medium enters the second flow channel through the third interface, exits the second flow channel through the first outlet, enters the third flow channel through the fourth interface, and exits the third flow channel through the second outlet.

[0035] The connecting part has a transition channel, and the third mounting hole communicates with the transition channel. The connecting part has a second inlet and a third outlet, both of which are connected to the transition channel. The working medium enters the transition channel from the second inlet and leaves the transition channel through the third outlet. The sensing element is assembled with the connecting part through the third mounting hole and can detect the temperature of the working medium in the transition channel.

[0036] The first inlet is located at the first end. In order to avoid the first inlet, the first hollow part and the second hollow part are spaced apart by a certain distance. The first groove and the second groove are connected. Other structures are not described in detail.

[0037] exist Figures 1 to 12In this embodiment, when the thermal management component is working, the high-temperature and high-pressure working medium enters the first flow channel 801 from the first inlet 30. The first valve section 11 and the second valve section 12 connect the first channel 71 or the second channel 72 according to the control command, and then the working medium leaves the first flow channel 801 from the first interface 10 or the second interface 20. The connecting part has a second inlet 8021 and a third outlet 8022. Both the second inlet 8021 and the third outlet 8022 are connected to the second flow channel 802. The working medium in the liquid storage section 3 can enter the second flow channel 802 of the connecting part 8 through the second inlet 8021. The third outlet 8022 serves as the outlet of the second flow channel. The third outlet 8022 can connect to the channel of the inner connecting bridge 506. The working medium entering the inner connecting bridge 506 can enter the cooler 6 or the intermediate heat exchanger 5.

[0038] When the thermal management component is working, the high-temperature and high-pressure working medium enters the first flow channel through the first inlet. The first valve section and the second valve section connect the first or second channel according to the control command, and then the working medium leaves the first flow channel through the first or second interface. The low-temperature and high-pressure working medium can enter the second flow channel through the third interface, or enter the third flow channel through the fourth interface. The working medium in the second flow channel can enter the liquid storage section through the first outlet, and the working medium in the third flow channel can enter the liquid storage section through the second outlet. The working medium in the liquid storage section enters the transition channel of the connecting section through the second inlet. The transition channel is connected to the third outlet. The third outlet can be connected to the channel of the inner connecting bridge. The working medium entering the inner connecting bridge can enter the cooler or intermediate heat exchanger.
