Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0043] The heat insulation mechanism 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0044] Reference Figures 1-3 As shown, the heat insulation mechanism 100 according to an embodiment of the present utility model may include: a liquid cooling plate 10.

[0045] Specifically, the liquid cooling plate 10 is movably located on one side of the heat insulation component. The liquid cooling plate 10 meets the heat insulation requirements of the heat insulation component, thereby addressing the heat damage needs of surrounding components. Furthermore, the coolant within the liquid cooling plate 10 can exchange heat with the heat insulation component, meeting its cooling requirements. Simultaneously, the separate design of the liquid cooling plate 10 and the heat insulation component avoids the poor maintainability issues caused by an integrated design in related technologies, resulting in better maintenance economy and reduced maintenance costs.

[0046] In related technologies, the liquid cooling plate and the heat insulation component are fixedly connected by welding. The coolant in the liquid cooling plate is always exchanging heat with the heat insulation component. Under high temperature and high load conditions, the load on the cooling system where the liquid cooling plate is located increases, thereby increasing the design and matching difficulty of the cooling system.

[0047] Therefore, in this utility model, as Figure 1 and Figure 2 As shown, the heat insulation component also includes a drive component 20, which is connected to the liquid cooling plate 10. The drive component 20 can drive the liquid cooling plate 10 to move towards or away from the heat insulation component. Therefore, by adjusting the distance between the liquid cooling plate 10 and the heat insulation component, the heat exchange capacity of the liquid cooling plate 10 can be actively adjusted. This allows for flexible adjustment of the heat exchange load based on the redundancy of the cooling system, active control of waste heat recovery, and temperature and noise reduction. It fully utilizes the redundant heat exchange capacity of the cooling system, resulting in minimal cooling system fluctuations and solving the problems of high cooling system load and difficult matching.

[0048] For example, when the cooling system is redundant, the drive assembly 20 drives the liquid cooling plate 10 to move towards the side closer to the heat insulation component. While the liquid cooling plate 10 performs its heat insulation function, it can also cool the heat insulation component, reduce its temperature, or perform heat recovery. When the cooling system is under high load, the drive assembly 20 can drive the liquid cooling plate 10 to move away from the heat insulation component. While meeting the heat insulation requirements of the heat insulation component, it can reduce the heat exchange of the liquid cooling plate 10, thereby reducing the load on the cooling system and meeting thermal management requirements.

[0049] According to the embodiment of the present invention, the heat insulation mechanism 100 is movably located on one side of the heat insulation component via a liquid cooling plate 10. The driving component 20 is connected to the liquid cooling plate 10 and is used to drive the liquid cooling plate 10 to move toward the side closer to or away from the heat insulation component. This allows the heat exchange capacity of the liquid cooling plate 10 to be actively adjusted by adjusting the distance between the liquid cooling plate 10 and the heat insulation component. This enables flexible adjustment of the heat exchange load based on the redundancy of the cooling system, active control of waste heat recovery, and cooling and noise reduction. This solves the problems of large cooling system load and difficult matching, and avoids the problem of poor maintainability caused by the liquid cooling plate and heat insulation component being integrated in related technologies, which helps to reduce maintenance costs.

[0050] In some embodiments of this utility model, the liquid cooling plate 10 has a first state and a second state. When the liquid cooling plate 10 is in the first state, the liquid cooling plate 10 and the heat insulation component are in contact, so that the liquid cooling plate 10 and the heat insulation component are in contact for heat exchange. That is, the wall surface of the heat insulation component transfers heat to the wall surface of the liquid cooling plate 10 through heat conduction. While the liquid cooling plate 10 plays a heat insulation role, it also cools the heat insulation component, reduces the temperature of the heat insulation component, or performs heat recovery. When the liquid cooling plate 10 is in the second state, the liquid cooling plate 10 and the heat insulation component are spaced apart, so that the wall surface of the heat insulation component exchanges heat with the air through convection. The air itself convects and the air exchanges heat with the wall surface of the liquid cooling plate 10. The heat exchange of the liquid cooling plate 10 is greatly reduced by the heat insulation of the intermediate air, so that the amount of heat transfer is reduced, and the heat exchange effect is reduced. Therefore, the heat insulation mechanism 100 of this utility model can greatly reduce the load of the cooling system while satisfying the heat insulation performance.

[0051] For example, when the cooling system is redundant, the liquid cooling plate 10 is in close contact with the heat insulation component for heat exchange, and while providing heat insulation, it also cools the heat insulation component, reduces the exhaust temperature, or performs heat recovery. When the cooling system is under high load, the liquid cooling plate 10 and the heat insulation component are spaced apart, and the heat exchange capacity of the liquid cooling plate 10 is greatly reduced by the heat insulation through the air in between, which greatly reduces the load on the cooling system while meeting the heat insulation performance.

[0052] In some embodiments, the distance between the liquid cooling plate 10 and the heat insulation component can be set according to actual conditions to meet different usage requirements.

[0053] According to some embodiments of this utility model, the maximum distance between the liquid cooling plate 10 and the heat insulation component is less than or equal to 30mm. This satisfies the heat insulation and cooling requirements of the liquid cooling plate 10 on the heat insulation component. Furthermore, while reducing the heat exchange capacity of the liquid cooling plate 10, it avoids the need for a large internal space due to the long movement distance of the liquid cooling plate 10, thus facilitating miniaturization. For example, in some specific embodiments, the maximum distance between the liquid cooling plate 10 and the heat insulation component can be 30mm, 28mm, 25mm, 20mm, 18mm, 15mm, etc.

[0054] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the liquid cooling plate 10 has an inlet 11 and an outlet 12. Both the inlet 11 and the outlet 12 are connected to a connecting pipe 13. The coolant can enter the liquid cooling plate 10 from the inlet 11 through the connecting pipe 13, flow in the liquid cooling plate 10 to absorb the heat of the heat insulation component, thereby cooling the heat insulation component. The coolant then flows out from the connecting pipe 13 through the outlet 12 to achieve the circulation of the coolant and ensure a good heat exchange effect on the heat insulation component.

[0055] In addition, part of the connecting pipe 13 is a flexible hose, which makes it easy to bend the connecting pipe 13, making the setting position of the connecting pipe 13 more flexible. When the liquid cooling plate 10 moves, the flexible hose can absorb the movement gap, prevent the connecting pipe 13 from moving relative to the whole, and ensure the reliability of the movement of the liquid cooling plate 10.

[0056] According to some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the connecting pipe 13 includes a first connecting pipe 131 and a second connecting pipe 132. The two ends of the first connecting pipe 131 along its length are connected to the second connecting pipe 132 and the inlet 11 or outlet 12, respectively, fulfilling the connection requirements between the connecting pipe 13 and the inlet 11 or outlet 12. The first connecting pipe 131 is a metal component, while the second connecting pipe 132 is a flexible hose. Therefore, since the temperatures at the inlet 11 and outlet 12 are relatively high, the metal first connecting pipe 131 provides a transition, preventing the second connecting pipe 132 from being at risk of heat damage and thus avoiding deformation. Furthermore, the flexible second connecting pipe 132 can absorb movement gaps, ensuring the reliable movement of the liquid cooling plate 10. For example, the second connecting pipe 132 can be made of rubber.

[0057] In the embodiments of this utility model, the specific structure of the driving component 20 can be set according to the actual situation.

[0058] For example, in some embodiments, the drive assembly 20 can be an electric actuator or a linear motor, enabling the drive assembly 20 to drive the liquid cooling plate 10 toward the side closer to or away from the heat insulation component, ensuring simple and reliable drive, more convenient control, and easy active control of the heat insulation component.

[0059] In some embodiments, such as Figure 2 and Figure 4 As shown, the electric linear actuator includes a motor 201 and a linear actuator 202. The motor 201 can use 12V low-voltage DC power to drive the linear actuator 202 to move. The linear actuator 202 has a self-locking function, which can stop the motor 201 by cutting off the power at any position, preventing the motor 201 from running dry and burning out, and ensuring safety during use. For example, the motor 201 can be a permanent magnet DC motor 201.

[0060] For example, when the liquid cooling plate 10 is used for exhaust cooling or waste heat utilization, the electronic control unit (ECU) sends a heat recovery or exhaust temperature reduction signal. The controller receives the signal and controls the electric push rod to work. The electric push rod pulls the liquid cooling plate 10 to move towards the side closer to the heat insulation component, and locks the position of the liquid cooling plate 10 through the self-locking function of the electric push rod, thus fixing the position of the liquid cooling plate 10.

[0061] When the liquid cooling plate 10 stops exhaust cooling or waste heat utilization, or when the cooling system has reached its maximum load, the ECU sends a relevant signal, the controller receives the signal, and controls the electric push rod to push the liquid cooling plate 10 to move away from the heat insulation component. After being pushed to the designated position, the electric push rod self-locks, fixing the position of the liquid cooling plate 10.

[0062] It is understood that the specific structures of electric linear actuators and linear motors are well known to those skilled in the art and will not be described in detail here.

[0063] For example, in some embodiments, the drive assembly 20 includes a motor and a transmission component connected to the motor and the liquid cooling plate 10. The transmission component can convert the rotational output of the motor into linear movement of the liquid cooling plate 10, thereby fulfilling the drive assembly 20's requirement to drive the liquid cooling plate 10 toward the side closer to or away from the heat insulation component, ensuring reliable drive and facilitating active control of the heat insulation component.

[0064] In some embodiments of this utility model, the transmission component includes a gear and a rack. The gear is connected to a motor, and the rack is connected to the liquid cooling plate 10, with the rack meshing with the gear. Thus, when the motor drives the gear to rotate, the gear can drive the rack to move by meshing with it, allowing the rack to drive the liquid cooling plate 10 to move towards or away from the heat insulation component, meeting the required movement needs. Furthermore, the transmission component has a simple structure, which can reduce production costs.

[0065] According to some embodiments of the present invention, the drive assembly 20 is disposed on the heat insulation component, which can realize the fixing requirements of the drive assembly 20, ensure that the liquid cooling plate 10 is convenient and reliable to drive, and make the structure compact, thereby reducing the space occupied by the heat insulation mechanism 100.

[0066] In some embodiments, such as Figure 1 and Figure 2 As shown, the heat insulation mechanism 100 includes a bracket 21, which is connected to the drive assembly 20 and the heat insulation component. The drive assembly 20 can be fixed on the heat insulation component through the bracket 21, ensuring that the drive assembly 20 is reliably fixed on the heat insulation component.

[0067] In some embodiments of this utility model, the drive assembly 20 and the liquid cooling plate 10 are connected by fasteners 51 or welded together to ensure that the drive assembly 20 and the liquid cooling plate 10 are reliably connected and to avoid problems such as mutual slippage. This makes the drive assembly 20 drive the liquid cooling plate 10 to move more reliably and is easier to assemble, which is beneficial to improving assembly.

[0068] In some embodiments where the drive assembly 20 is an electric linear actuator, such as Figure 4 As shown, the push rod 202 of the electric push rod has a connection hole 22 at one end near the liquid cooling plate 10. The fastener 51 passes through the liquid cooling plate 10 and connects with the connection hole 22 to ensure that the push rod 202 is reliably connected to the liquid cooling plate 10, and is easy to disassemble, maintain or replace, etc.

[0069] According to some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, a guide member 31 is provided on the end face of the heat insulation component facing the liquid cooling plate 10, and a guide portion 14 is provided on the liquid cooling plate 10. Thus, through the cooperation of the guide portion 14 and the guide member 31, the movement of the liquid cooling plate 10 can be guided, avoiding problems such as displacement of the liquid cooling plate 10 and ensuring reliable movement. For example, the guide member 31 can be a guide rail, and the guide portion 14 can be a slider.

[0070] In some embodiments, such as Figure 1 and Figure 3 As shown, there are multiple guide members 31, which are spaced apart on one end face of the heat insulation member facing the liquid cooling plate 10. There are multiple guide parts 14 that correspond one-to-one with the multiple guide members 31. By cooperating with the multiple guide parts 14 and the multiple guide members 31, the movement of the liquid cooling plate 10 at multiple different positions can be guided, ensuring reliable movement and avoiding deviation.

[0071] In embodiments of this utility model, the number of guide members 31 can be flexibly set according to actual conditions. For example, the guide members 31 can be as follows: Figure 1The number shown is four, but it can also be two, three, five, six or more, all of which are within the protection scope of this utility model.

[0072] The exhaust system assembly 300 according to an embodiment of the present invention includes an exhaust system 200 and a heat insulation mechanism 100 according to an embodiment of the present invention. The exhaust system 200 is configured as a heat insulation component. A liquid cooling plate 10 is movably located on one side of the exhaust system 200. A driving assembly 20 can drive the liquid cooling plate 10 to move toward or away from the exhaust system 200. The liquid cooling plate 10 can exchange heat and cool the exhaust system 200, thereby reducing the temperature of the airflow in the exhaust system 200, thus reducing the airflow velocity and exhaust resistance in the exhaust system 200, and achieving the requirement of reducing exhaust noise. At the same time, by adjusting the distance between the liquid cooling plate 10 and the heat insulation component, the heat exchange capacity of the liquid cooling plate 10 can be actively adjusted. This allows for flexible adjustment of the heat exchange load according to the redundancy of the cooling system, active control of waste heat recovery and cooling and noise reduction, etc., which can fully utilize the redundant heat exchange capacity of the cooling system, with small changes in the cooling system, solving the problems of large cooling system load and difficult matching.

[0073] In related technologies, the exhaust gas discharged by the engine through the exhaust system has high heat, and this energy is ultimately released into the atmosphere without being fully utilized. Furthermore, the exhaust gas from the exhaust system is not cooled, resulting in excessively high exhaust outlet temperatures. Therefore, in this invention, the liquid cooling plate 10 can exchange heat and cool the exhaust system 200, reducing the temperature of the airflow within the exhaust system 200. This reduces the airflow velocity and exhaust resistance within the exhaust system 200, thus achieving the goal of reducing exhaust noise. Additionally, the liquid cooling plate 10 enables the recovery of waste heat from the exhaust system 200.

[0074] In related technologies, exhaust systems require airflow bypass for active heat recovery. The heat exchange device (e.g., a heat recovery unit) is located on the main exhaust channel and can only operate at engine idle or low load. Under high load and high exhaust flow conditions, airflow bypass significantly increases the exhaust system back pressure. Opening the heat exchange device would greatly increase exhaust resistance, affecting engine power and fuel economy, thus making heat exchange and cooling impossible under high load conditions. Therefore, in this invention, by positioning the liquid cooling plate 10 outside the exhaust system 200, active waste heat recovery is achieved without affecting the exhaust flow path, and airflow bypass is not required. This allows operation under various conditions, meeting different usage requirements.

[0075] Since the heat insulation mechanism 100 according to the present invention has the above-mentioned beneficial technical effects, the exhaust system assembly 300 according to the present invention is movably located on one side of the heat insulation component via the liquid cooling plate 10. The drive assembly 20 is connected to the liquid cooling plate 10 and is used to drive the liquid cooling plate 10 to move toward the side closer to or away from the heat insulation component. This allows the heat exchange capacity of the liquid cooling plate 10 to be actively adjusted by adjusting the distance between the liquid cooling plate 10 and the heat insulation component. This enables flexible adjustment of the heat exchange load according to the redundancy of the cooling system, active control of waste heat recovery, and cooling and noise reduction. This solves the problems of large cooling system load and difficult matching, and avoids the problem of poor maintainability caused by the liquid cooling plate and heat insulation component being integrated in related technologies, which helps to reduce maintenance costs.

[0076] In some embodiments of this utility model, such as Figure 1 As shown, the exhaust system 200 includes a muffler 41, which reduces noise generated during exhaust, such as the noise generated during engine exhaust, thus achieving the required noise reduction. Furthermore, a liquid cooling plate 10 is movably located on one side of the muffler 41. The liquid cooling plate 10 meets the heat insulation requirements of the muffler 41, thereby meeting the heat protection requirements of the surrounding components. The coolant within the liquid cooling plate 10 can exchange heat with the muffler 41, meeting the cooling requirements of the muffler 41, thereby reducing the airflow velocity through the muffler 41 and further reducing noise.

[0077] According to some embodiments of this utility model, such as Figure 1 As shown, the muffler 41 includes a muffler body and a housing 411. The housing 411 is fitted over the muffler body and can protect the muffler body.

[0078] Since the heat transfer power of the liquid cooling plate 10 is mainly affected by the heat transfer area and the heat transfer coefficient, the convective heat transfer coefficient between the liquid cooling plate 10 and the shell 411 is large (e.g., 2000 W / m). 2 The convective heat transfer coefficient between the sound-absorbing body and the shell 411 is small (e.g., less than 100 W / m²). 2 Therefore, the key factor affecting the heat transfer in the heat transfer path is the heat transfer value between the silencer body and the shell 411. According to the heat transfer principle, fins are provided on the inner wall surface of the shell 411 opposite to the liquid cooling plate 10. The fins can effectively increase the heat transfer area, increase the heat transfer inside the silencer 41, facilitate heat exchange between the liquid cooling plate 10 and the shell 411, thereby increasing the total heat transfer and ensuring a better cooling effect on the silencer 41.

[0079] In some embodiments of this utility model, such as Figure 1As shown, the exhaust system 200 also includes a catalytic converter 42, which can purify exhaust gas and reduce exhaust gas pollution to the air. The catalytic converter 42 is connected to the muffler 41, and the liquid cooling plate 10 is located on the side of the muffler 41 away from the catalytic converter 42, which makes the exhaust system 200 compact in structure, reduces the space occupied, facilitates the miniaturization design of the exhaust system 200, and reduces the distance between the airflow through the catalytic converter 42 and the muffler 41, making the airflow smoother.

[0080] For example, in some embodiments, the liquid cooling plate 10 has a first state and a second state. When the liquid cooling plate 10 performs exhaust cooling or waste heat utilization, the exhaust gas generated by the engine combustion is a high-temperature gas. After being purified by the catalytic converter 42, the exhaust gas enters the muffler 41. When the ECU sends a heat recovery or exhaust temperature reduction signal, the controller receives the signal and controls the drive assembly 20 to work. The drive assembly 20 drives the liquid cooling plate 10 to move toward the side closer to the heat insulation component. Finally, the liquid cooling plate 10 and the muffler 41 are in contact. The liquid cooling plate 10 is in the first state and exchanges heat with the high-temperature gas through the wall of the muffler 41. The liquid cooling plate 10 exchanges heat with the wall of the muffler 41 to realize the exhaust cooling or waste heat utilization function.

[0081] When the liquid cooling plate 10 stops exhaust cooling or waste heat utilization, when exhaust cooling or waste heat utilization is not required, or when the cooling system has reached its maximum load, the ECU sends a relevant signal, the controller receives the signal, and controls the drive assembly 20 to drive the liquid cooling plate 10 to move away from the heat insulation component, so that the liquid cooling plate 10 and the muffler 41 are spaced apart. The liquid cooling plate 10 is in the second state, and the heat exchange of the liquid cooling plate 10 is reduced by air insulation between the liquid cooling plate 10 and the muffler 41. While meeting the heat insulation performance, the function of stopping heat exchange and reducing the load of the cooling system is realized.

[0082] The vehicle according to an embodiment of the present invention includes an exhaust system assembly 300 according to an embodiment of the present invention. Since the exhaust system assembly 300 according to an embodiment of the present invention has the aforementioned beneficial technical effects, the vehicle according to an embodiment of the present invention, with a liquid cooling plate 10 movably located on one side of a heat insulation component, and a drive assembly 20 connected to the liquid cooling plate 10 for driving the liquid cooling plate 10 to move towards or away from the heat insulation component, allows for active adjustment of the heat exchange capacity of the liquid cooling plate 10 by adjusting the distance between the liquid cooling plate 10 and the heat insulation component. This enables flexible adjustment of the heat exchange load based on the redundancy of the cooling system, active control of waste heat recovery, and cooling and noise reduction, solving the problems of high cooling system load and difficult matching, and avoiding the poor maintainability caused by the integrated design of the liquid cooling plate and heat insulation component in related technologies, thus helping to reduce maintenance costs.

[0083] In some embodiments, the exhaust system component 300 is applied to a vehicle. The heat insulation mechanism 100 can meet the heat requirements of the components around the exhaust system 200, and provides actively controllable waste heat recovery and cooling and noise reduction functions. It can meet the functions of rapid powertrain warm-up, cabin auxiliary heating, battery insulation, exhaust temperature reduction, and acoustic performance improvement, and can meet different usage needs.

[0084] According to some embodiments of this utility model, the exhaust system assembly 300 is located in the front compartment of the vehicle, which makes the vehicle's internal structure compact and helps to reduce the space occupied by the exhaust system assembly 300, thus meeting the required installation requirements. Because the front compartment houses many components and has a compact space, the energy of the exhaust system 200 is concentrated. Compared with related technologies that use heat insulation cotton for insulation, this utility model achieves the insulation requirement through a liquid cooling plate 10, which reduces the space occupied and facilitates miniaturization.

[0085] Furthermore, since the exhaust system 200 is located in the front compartment, its internal airflow temperature is higher than that of through-type exhaust systems in related technologies. This higher temperature can easily lead to increased exhaust airflow velocity, affecting acoustic performance and making acoustic matching of the exhaust system more difficult. It also increases exhaust resistance, impacting vehicle power and fuel economy. Therefore, this invention effectively cools the exhaust system 200 using the liquid cooling plate 10, for example, by stably reducing the surface temperature of the exhaust system 200 to approximately 100°C. This reduces the airflow velocity and exhaust resistance within the exhaust system 200, achieving the goal of reducing exhaust noise and improving the passenger experience.

[0086] The heat insulation mechanism 100, the exhaust system assembly 300, and other components and operations of the vehicle according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
