[0015] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0016] refer to Figure 1 and Figure 2This application discloses a thermal management component, characterized in that it includes a gas-liquid separation component 2, a flow channel component 1, and a support frame 3. The flow channel component 1 includes a flow channel plate in a split connection form and a valve island in an integral form. The gas-liquid separation component 2 includes a gas-liquid separator or a liquid reservoir. The flow channel component 1 has a flow channel 10, and the gas-liquid separation component 2 has a gas-liquid separation chamber 20. One end of the support frame 3 is connected to the gas-liquid separation component 2, and the other end of the support frame 3 is connected to the flow channel component 1. The thermal management component includes a connecting pipe 4, which is fixedly connected or limitedly connected to the support frame 3. The fixed connection includes connection methods such as welding, riveting, and fastening with fasteners to fix the relative position of the connecting pipe and the support frame. The limited connection includes connection methods such as at least a portion of the connecting pipe being snapped or sleeved with the support frame, or at least a portion of the connecting pipe being embedded in the support frame to limit the large displacement of the connecting pipe by the support frame. The connecting pipe 4 has a pipe 40, which can connect the flow channel 10 and the gas-liquid separation chamber 20. In the above embodiments, the connecting pipe 4 can be directly and fixedly connected to the flow channel component 1 and the gas-liquid separation component 2, or it can be indirectly connected to the flow channel component 1 and the gas-liquid separation component 2 through the support frame 3. By connecting the flow channel component 1 and the gas-liquid separation component 2 through the support frame 3, and fixing or limiting the connecting pipe 4 used to connect the gas-liquid separation chamber 20 and the flow channel 10 to the support frame 3, the force exerted by the gas-liquid separation component 2 on the connecting pipe 4 is at least partially distributed to the support frame 3. The support frame 3 can provide a certain structural strength for the connecting pipe 4. In other words, the support frame 3 can enhance the deformation resistance of the connecting pipe 4, or the support frame 3 can limit the degree of deformation of the connecting pipe 4, making the connecting pipe 4 less prone to deformation and breakage under vibration conditions, ensuring the effectiveness of the connection between the flow channel component 1 and the gas-liquid separation component 2, thereby improving the connection stability of the entire thermal management assembly.

[0017] refer to Figure 1 and Figure 3In some embodiments, to facilitate the fixed connection between the connecting pipe 4 and the support frame 3 and to avoid the connecting pipe 4 bearing excessive load pressure, the connecting pipe 4 includes a first end 41 and a second end 42. The first end 41 and the second end 42 represent a short section of pipe wall near the two ports of the connecting pipe 4. The support frame 3 is an integral structure, and at least one of the first end 41 and the second end 42 is fixedly connected to the corresponding first connecting part 31 and the second connecting part 32. In this way, one end of the connecting pipe 4 can be connected to one of the flow channel component 1 and the gas-liquid separation component 2, and the other end of the connecting pipe is fixedly connected to the support frame 3. The support frame 3 is fixedly connected to the other of the flow channel component 1 and the gas-liquid separation component 2. When the flow channel component 1 and the gas-liquid separation component 2 vibrate relative to each other, the position of the end of the connecting pipe 4 connected to the flow channel component 1 or the gas-liquid separation component 2 relative to the support frame 3 is relatively fixed, and the other end of the connecting pipe 4 is fixed to the support frame 3. The support frame 3 is fixedly connected, so the support frame 3 will share a large amount of the load-bearing pressure, and the pipe 4 itself will not undergo large deformation. The connection between the flow channel component 1 and the gas-liquid separation component 2 is relatively more stable. Furthermore, in order to ensure better reinforcement of the pipe 4, the first end 41 is fixedly connected or limited to the support frame 3, and the second end 42 is fixedly connected or limited to the support frame 3. The two ends of the pipe 4 are fixed or limited by the support frame 3, and the support frame 3 is an integral structure. On the one hand, fixing the two ends of the pipe 4 to the support frame 3 can strengthen the overall strength of the pipe 4. The support frame 3 can enhance the deformation resistance of the entire pipe 4. In other words, the deformation of any part of the pipe 4 needs to resist the integral structure of the support frame 3. The support frame 3 provides more comprehensive structural reinforcement of the pipe 4. On the other hand, the connection points between the pipe 4 and the support frame 3 are only at the two ends, which is convenient to manufacture.

[0018] Furthermore, in this embodiment, reference is made to... Figure 6The support frame 3 includes a first connecting portion 31 and a second connecting portion 32. At least one of the first end portion 41 and the second end portion 42 is fixedly connected to the corresponding first connecting portion 31 and the second connecting portion 32. The corresponding first connecting portion 31 and the second connecting portion 32 have channels 30. One end of the channel 30 is connected to the pipe 40, and the other end of the channel is connected to the corresponding gas-liquid separation chamber 20 or flow channel 10. That is, when the first end portion 41 is fixedly connected to the first connecting portion 31, the first connecting portion 31 has a channel 30 connecting the pipe 40 and the flow channel 10; when the second end portion 42 is fixedly connected to the second connecting portion 32, the second connecting portion 32 has a channel 30 connecting the pipe 40 and the gas-liquid separation chamber 20; when the first end portion 41 .... When the second end 42 is fixedly connected to the first connecting part 31 and the second connecting part 32 respectively, the first connecting part 31 has a channel 30 connecting one end of the pipe 40 to the flow channel 10, and the second connecting part 32 also has a channel 30 connecting the other end of the pipe 40 to the gas-liquid separation chamber 20. In this way, at least one end of the pipe 4 is indirectly connected to the flow channel component 1 or the gas-liquid separation component 2 through the support frame 3. The channel 30 connecting the pipe 40 to the flow channel 10 or the gas-liquid separation chamber 20 is set on the support frame 3. Under vibration conditions, the flow channel component 1 and the gas-liquid separation component 2 vibrate relative to each other. At least one end of the pipe 4 does not have to directly bear the force caused by this vibration, which can prevent the pipe 4 from undergoing large deformation and breakage under vibration conditions. In addition, channels 30 are provided on the first connecting part 31 and the second connecting part 32 respectively, so that the pipe 4 can be fixedly connected to the support frame 3, and the flow channel component 1 or the gas-liquid separation component 2 can be fixedly connected to the support frame. The wall of the support frame forming the channel 30 can be sealed with the pipe 4, the corresponding flow channel component 1 and the gas-liquid separation component 2 respectively. In the manufacturing process, compared with the pipe 4 passing through the support frame 3 to seal with the flow channel component 1 or the gas-liquid separation component 2, the sealing method of this embodiment is more reliable, the dimensional chain is not too long, the error is relatively controllable, and the manufacturing is relatively easy.

[0019] In some embodiments, both ends of the connecting pipe 4 are indirectly connected to the flow channel component 1 and the gas-liquid separation component 2 respectively via the support frame 3. In this way, the weight of the gas-liquid separation component 2 is distributed to the support frame 3 to the greatest extent. Under vibration conditions, the force caused by the relative vibration of the flow channel component 1 and the gas-liquid separation component 2 is entirely borne by the connection part of the support frame 3 to the gas-liquid separation component 2 and the flow channel component 1. The overall structure of the connecting pipe 4 is not affected by the vibration force, making the connection of the entire thermal management assembly more stable. Specifically, in this embodiment, the first connecting part 31 has a first channel 310, and the second connecting part 32 has a second channel 320. One end of the first channel 310 is connected to the flow channel 10, and the other end of the first channel 310 is connected to the pipe 40. One end of the second channel 320 is connected to the gas-liquid separation chamber 20, and the other end of the second channel 320 is connected to the pipe 40. The first end 41 and the second end 42 are fixedly connected to the first connecting part 31 and the second connecting part 32 respectively.

[0020] refer to Figure 6 and Figure 7 To facilitate the connection between the support frame 3 and the flow channel component 1 and the gas-liquid separation component 2, and to facilitate the connection between the pipe 4 and the support frame 3, in this embodiment, the first connecting part 31 includes a first side part 311 and a second side part 312. The first side part 311 is fixedly connected to the flow channel component 1, preferably by fasteners. The second side part 312 is welded and fixed to the first end 41 of the pipe 4. The second connecting part 32 includes a third side part 321 and a fourth side part 322. The third side part 321 is fixedly connected to the gas-liquid separation component 2, preferably by fasteners. The fourth side part 322 is welded and fixed to the second end 42 of the pipe 4. The first side part 311 and the second side part 312 are located on opposite sides of the first connecting part 31. The opening of the second side part 312 for connecting the pipe 4 is in the same direction as the opening of the fourth side part 322 for connecting the pipe 4.

[0021] refer to Figure 1 and Figure 3 To avoid the main flow channel of the flow channel component 1 being too far from the gas-liquid separation component 2, which would require the support frame 3 and the connecting pipe 4 to bear a large supporting pressure, in this embodiment, an extension 12 is provided on the flow channel component 1 to appropriately shorten the distance between the main flow channel of the flow channel component 1 and the gas-liquid separation component 2. Specifically, in this embodiment, the flow channel component 1 includes a main body 11 and an extension 12, which are integrally formed. Along the thickness direction perpendicular to the flow channel component 1, the extension 12 extends from the main body 11 towards the gas-liquid separation component 2. The gas-liquid separation component 2 includes a sealing head 21 and a tank body 22, the central axis of which is approximately perpendicular to the center of gravity. The forces are parallel, and the head 21 and the tank body 22 are arranged vertically along the direction of gravity. The head 21 and the tank body 22 are welded and fixed, forming the wall of the gas-liquid separation chamber 20 located between the head 21 and the tank body 22. The first connecting part 31 of the support frame 3 is fixedly connected to the extension 12, and the second connecting part 32 is fixedly connected to the head 21 of the gas-liquid separation component 2. In this embodiment, the central axis of the gas-liquid separation component 2 is approximately located at the end face of the extension 12 away from the main body 11. The extension 12 extends this distance so that the distance between the main body 11 and the gas-liquid separation component 2 is relatively short. Consequently, the extension length of the support frame 3 and the connecting pipe 4 is shorter, which is beneficial to improving the connection stability of the entire thermal management assembly. It should be noted that the integral structure of the extension 12 and the main body 11 not only represents that the flow channel component 1 itself is integrally formed, but also that the extension 12 and the main body 11 are integrally formed, and also represents that, as Figure 1 As shown, the flow channel component 1 is made by welding together multiple plates, and at least a portion of the plate forming the extension is integrally formed with a portion of the plate forming the main body.

[0022] To rationally arrange the gas-liquid separation component 2 and the flow channel component 1, and to facilitate later maintenance, the thermal management assembly includes a first fastener 71 and a second fastener 72. The extension direction of the extension 12 is perpendicular to the direction of gravity, including an angle of 80 to 100 degrees between the extension direction of the extension 12 and the direction of gravity. Along the extension direction of the extension 12, the first fastener 71 is fixedly connected to the first connecting part 31 and the extension 12. Along the direction of gravity, the second fastener 72 is fixedly connected to the second connecting part 32 and the end cap 21. In other words, the first fastener 71 and the corresponding connecting hole are consistent with the extension direction of the extension 12, and the second fastener 72 and the corresponding connecting hole are consistent with the direction of gravity. This means that the extension direction of the first fastener 71 and the extension direction of the second fastener 72 are approximately perpendicular. The support frame 3 is fixedly connected to the gas-liquid separation component 2 and the flow channel component 1 in two directions, which can improve the connection stability of the gas-liquid separation component 2 and the flow channel component 1.

[0023] To further improve the connection stability of the entire thermal management assembly, in this embodiment, multiple vehicle connection parts connected to the vehicle are respectively distributed on the main body 11 and extension 12 of the flow channel component 1. Specifically, the extension 12 includes a flow channel 121 and a vehicle connection 122, which are arranged vertically along the axial direction of the gas-liquid separation component. Part of the flow channel 10 is located in the flow channel 121. The vehicle connection 122 is used to connect with the vehicle crossbeam. The support frame 3 includes a support beam 33, which connects the first connection part 31 and the second connection part 32. The support beam 33 is fixedly connected to the vehicle connection part 122. The support beam 33 is located in the middle of the support frame 3 and includes a first beam segment 331, a second beam segment 332, and a turning segment 333. 1. The first connecting part 31 and the turning section 333 are connected. The second beam section 332 connects the second connecting part 32 and the turning section 333. The first beam section 331 extends from the flow channel part 121 toward the vehicle connecting part 122. The second beam section 332 extends from the vehicle connecting part 122 toward the gas-liquid separation component 2. The turning section 333 is located in the middle section of the support beam 33. The turning section 333 is fixedly connected to the vehicle connecting part 122. On the one hand, it can improve the connection stability between the support frame 3 and the flow channel component 1, thereby improving the connection stability of the pipe 4 and the connection stability of the entire thermal management assembly. On the other hand, the vehicle connecting part 122 is connected to the vehicle crossbeam through the shock-absorbing pad. The support frame 3 is as close as possible to the vehicle connecting part 122 and fixed to the vehicle connecting part 122, which can improve the shock resistance of the support frame 3 and the pipe 4.

[0024] In this embodiment, the thermal management component further includes a valve component and a heat exchanger. The valve component and the heat exchanger are located in the main body 11. The main body 11 has multiple first flow channels 110. The first flow channels 110 can connect to the refrigerant channel of the valve component and the refrigerant channel of the heat exchanger. The flow channel section 121 of the extension 12 has a gas-liquid separator inlet flow channel 120. The gas-liquid separator inlet flow channel 120 connects to the corresponding first flow channel 110. The pipe 40 of the connecting pipe 4 connects the gas-liquid separator inlet flow channel 120 and the gas-liquid separation chamber 20.

[0025] refer to Figure 4 and Figure 5 In some embodiments, the flow channel component 1 includes a first protruding tube portion 61, which protrudes relative to the side wall of the flow channel component 1. The internal channel of the first protruding tube portion 61 communicates with the flow channel 10. The support frame 3 has a first insertion cavity 3110 with an opening facing the first protruding tube portion 61. The first protruding tube portion 61 is at least partially located in the first insertion cavity 3110. The support frame 3 has a second protruding tube portion 62, which protrudes. The gas-liquid separation component 2 has a second insertion cavity 210 with an opening facing the second protruding tube portion 62. The second protruding tube portion 62 is at least partially located in the second insertion cavity 210. The arrangement of the gas-liquid separation component varies depending on the vehicle model. In some models, to achieve a compact structure for the entire thermal management assembly, the support frame 3 and the connecting pipe 4 are removed, and the gas-liquid separation component 2 is directly connected to the flow channel component 1. In this embodiment, one of the connecting parts of the support frame 3 has a protruding tube, and the other connecting part has an insertion cavity for the protruding tube to be inserted. This means that one end of the support frame 3 is a male connector and the other end is a female connector. Correspondingly, the connection point of the flow channel component 1 and the connection point of the gas-liquid separation component 2 are also male connectors and female connectors, respectively. In this way, without changing the structure of the flow channel component 1 and the gas-liquid separation component 2 as much as possible, only the support frame 3 and the connecting pipe 4 are removed to assemble and manufacture a thermal management component suitable for another vehicle model. It should be noted that the gas-liquid separation component structure suitable for the above function is not shown in the accompanying drawings of this embodiment. However, it can be imagined that by setting the insertion cavity of the gas-liquid separation component in the accompanying drawings of this embodiment on the side of the protrusion on the top of the cover, and the extension direction of the first protruding tube 61 is consistent with the extension direction of the peripheral sidewall of the second insertion cavity 210 formed on the gas-liquid separation component, the above function can be achieved.

[0026] refer to Figure 1 , Figure 2 and Figure 8In this embodiment, to further strengthen the stable connection between the gas-liquid separation component 2 and the flow channel component 1, and to share the load-bearing pressure of the support frame 3 and the connecting pipe 4, the gas-liquid separation component 2 includes a sealing head 21 and a tank body 22. The thermal management component also includes an auxiliary support 5. The support frame 3 is fixedly connected to the sealing head 21 and the flow channel component 1, and the auxiliary support 5 is fixedly connected to the tank body 22 and the flow channel component 1. Along the axial direction of the gas-liquid separation component 2, the orthographic projection of the auxiliary support 5 is located on one side of the orthographic projection of the support frame 3. In other words, the orthographic projection of the auxiliary support 5 and the orthographic projection of the support frame 3 basically do not overlap. Thus, the distribution of the support connection points between the gas-liquid separation component 2 and the flow channel component 1 is reasonable, and the connection between the gas-liquid separation component 2 and the flow channel component 1 is more stable. Specifically, in this embodiment, referring to... Figure 8 The approximate extension direction of the orthographic projection of the support frame 3 is along the M line, and the approximate extension direction of the orthographic projection of the auxiliary support 5 is along the N line. There is an angle between the M line and the N line. Thus, along the axial direction of the gas-liquid separation component 2, the projections of the flow channel component 1, the support frame 3, and the auxiliary support 5 roughly form a triangle, making the connection between the gas-liquid separation component 2 and the flow channel component 1 more stable.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still make modifications or equivalent substitutions to the present invention.
