[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0030] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0031] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0032] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

[0033] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0034] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0035] This application provides a vehicle. It should be noted that the vehicle in this application can refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. For vehicles, a large amount of high-temperature exhaust gas is generated during operation. This exhaust gas is directly discharged into the atmosphere after undergoing a catalytic reaction, resulting in a significant waste of energy as a large amount of heat energy in the exhaust gas is not fully utilized.

[0036] Based on this, the present application provides an energy recovery device 100, which includes an exhaust gas pipe 10, a plurality of heat exchange modules 20 and a heat exchanger 41. The exhaust gas pipe 10 is located along a first direction (e.g., refer to the attached diagram). Figure 1 Extending in the X direction, the exhaust pipe 10 is suitable for transmitting exhaust gas, which is the high-temperature exhaust gas discharged from the vehicle.

[0037] For example, the exhaust gas pipe 10 can be a cylindrical pipe with the first direction being the axial direction of the exhaust gas pipe 10; the exhaust gas pipe 10 can also be a rectangular pipe with the first direction being the length direction of the exhaust gas pipe 10.

[0038] Multiple heat exchange modules 20 are arranged along a first direction within the exhaust gas duct 10, and the multiple heat exchange modules 20 are spaced apart along the first direction. A silencing cavity 11 is formed between two adjacent heat exchange modules 20. For example, three heat exchange modules 20 are provided in the exhaust gas duct 10, and two silencing cavities 11 are formed between the three heat exchange modules 20. Each heat exchange module 20 includes multiple core tubes 21 communicating with the silencing cavity 11. The multiple core tubes 21 are spaced apart to form a liquid flow channel 25. The heat exchange module 20 abuts against the inner wall of the exhaust gas duct 10 to isolate the silencing cavity 11 from the liquid flow channel 25.

[0039] After the exhaust gas enters the exhaust gas pipe 10, it then enters the core tube 21 of the heat exchange module 20, and is transported to the silencing chamber 11 through the core tube 21. Then it enters the core tube 21 of the adjacent heat exchange module 20 again, and then enters another silencing chamber 11 before finally being discharged into the external environment.

[0040] The exhaust gas is transported to the silencing chamber 11 through the core tube 21. The silencing chamber 11 is a spatial cavity that can reduce the noise energy in the exhaust gas, thereby achieving a silencing effect. For example, a resonator can be arranged inside the silencing chamber 11 to absorb sound energy of a specific frequency, which can further weaken the noise energy in the exhaust gas.

[0041] Reference Figure 2 , Figure 2 The arrows indicate the flow direction of the heat exchange medium. The heat exchanger 41 and the liquid flow channel 25 of the heat exchange module 20 are connected by a liquid flow pipe. The liquid flow pipe is suitable for the flow of the heat exchange medium. The heat exchange medium flows through the liquid flow pipe into the liquid flow channel 25 of the heat exchange module 20, where it transfers heat with the exhaust gas in the core tube 21 to heat the heat exchange medium. For example, the heat exchange medium is water.

[0042] The heat exchange module 20 has multiple components, and the liquid flow channel 25 has multiple components. The heat exchanger 41 is connected to the corresponding liquid flow channel 25 through multiple liquid flow pipes.

[0043] The heat exchanger 41 is connected to the cabin and other areas requiring heating in the vehicle, and heats the cabin and other areas requiring heating in the vehicle through the heat exchanger 41.

[0044] The energy recovery device 100 provided in this application embodiment has multiple spaced heat exchange modules 20 arranged in the exhaust gas pipeline 10. A silencing cavity 11 is formed between two adjacent heat exchange modules 20. Each heat exchange module 20 has multiple core tubes 21 that communicate with the silencing cavity 11. The multiple core tubes 21 are spaced apart and have liquid flow channels 25 that communicate with the heat exchanger 41. The silencing cavity 11 can reduce the noise energy in the exhaust gas and achieve the silencing effect. When the exhaust gas is transported in the core tubes 21, it can heat the heat exchange medium to provide heat value to the heat exchanger 41. The energy recovery device 100 can not only reduce the noise energy of the exhaust gas, but also utilize the high-temperature waste heat in the exhaust gas.

[0045] Reference Figures 1-5 In one possible implementation of this application, the heat exchange module 20 further includes partitions 22 located at both ends of the plurality of core tubes 21 in a first direction. The partitions 22 are used to separate the exhaust gas pipes 10 along the first direction. The partitions 22 are provided with a plurality of openings 221 that connect the core tubes 21 and the silencing cavity 11. The partitions 22 can separate the heat exchange module 20 from the silencing cavity 11 and prevent the heat exchange medium in the heat exchange module 20 from flowing into the silencing cavity 11.

[0046] For example, the exhaust gas duct 10 can be a cylindrical duct, and the baffle 22 is a central plate that abuts against the inner wall of the exhaust gas duct 10; the exhaust gas duct 10 can also be a rectangular duct, and the baffle 22 is a rectangular plate that abuts against the inner wall of the exhaust gas duct 10.

[0047] Reference Figures 2-4 In one possible implementation of this application, the partitions 22 of two adjacent heat exchange modules 20 are respectively a first partition 23 and a second partition 24. The first partition 23 has a plurality of first openings connecting the core tube 21 and the silencing cavity 11, and the second partition 24 has a plurality of second openings connecting the core tube 21 and the silencing cavity 11. The first openings and the second openings are staggered, that is, the arrangement positions of the openings 221 on the core tube 21 and the partition 22 of the adjacent heat exchange modules 20 are different.

[0048] The exhaust gas in the exhaust pipe 10 is transported through the core tube 21 from the first opening to the silencing cavity 11. Due to the staggered arrangement of the first and second openings, the exhaust gas flowing out from the first opening hits the second partition 24 and bounces back. The sound wave energy of the bounced exhaust gas and the downstream exhaust gas dissolves in the silencing cavity 11 to achieve the silencing effect.

[0049] Reference Figure 5In one possible implementation of this application, the core tubes 21 in each heat exchange module 20 are arranged in a row and column manner, and multiple interconnected liquid flow channels 25 are formed between the multiple core tubes 21 arranged in a row and column manner. The heat exchange medium flows through the liquid flow channels 25, which can increase the contact area between the heat exchange medium and the core tubes 21 and improve the heat exchange efficiency of the core tubes 21.

[0050] For example, the core tube 21 extends along the first direction, and each core tube 21 corresponds to two openings 221 on the partition plate 22. The core tubes 21 are arranged in rows and columns, and correspondingly, the openings 221 are also arranged in rows and columns on the partition plate 22.

[0051] Reference Figures 1-4 In one possible implementation of this application, the exhaust gas duct 10 is provided with an inlet 12 and an outlet 13, both of which are connected to the liquid flow channel 25. The inlet 12 and the outlet 13 are respectively located in a second direction of the exhaust gas duct 10 (for example, refer to the attached diagram). Figure 1 The two sides of the Y direction in the middle are separated by a first direction, wherein the first direction is perpendicular to the second direction.

[0052] When the heat exchange medium passes through the liquid flow channel 25, since the liquid inlet 12 and the liquid outlet 13 are located on both sides of the second direction of the exhaust gas pipe 10, the heat exchange medium can flow through the entire liquid flow channel 25, which can ensure the contact area between the heat exchange medium and the core tube 21.

[0053] For example, the exhaust gas pipe 10 extends along a first direction. The exhaust gas pipe 10 can be a cylindrical pipe, with the first direction being the axial direction of the exhaust gas pipe 10 and the second direction being the radial direction of the exhaust gas pipe 10; the exhaust gas pipe 10 can also be a rectangular pipe, with the first direction being the length direction of the exhaust gas pipe 10 and the second direction being the width direction of the exhaust gas pipe 10.

[0054] Reference Figures 1-2 In one possible implementation of this application, the energy recovery device 100 further includes a controller 42 and a drive 43. The drive 43 is disposed on the liquid pipe to drive the flow of the heat exchange medium in the liquid pipe, and the controller 42 is used to control the start and stop of the drive 43.

[0055] When heat exchanger 41 does not need to heat external components, controller 42 controls drive unit 43 to stop operating, the heat exchange medium in the liquid pipe stops flowing, and the heat exchange medium after exchanging heat with core tube 21 does not flow to heat exchanger 41, and heat exchanger 41 also stops heat exchange simultaneously. When heat exchanger 41 needs to heat external components, controller 42 controls drive unit 43 to start operating, the heat exchange medium after exchanging heat with core tube 21 begins to flow and flows to heat exchanger 41, and heat exchanger 41 heats external components.

[0056] For example, the drive unit 43 is an electronic water pump, and the controller 42 is electrically connected to the electronic water pump through the first wiring harness 45.

[0057] Reference Figures 1-2 In one possible implementation of this application, the liquid-passing pipe includes an inlet pipe 31 and an outlet pipe 32. The inlet pipe 31 connects the heat exchanger 41 to the inlet 12 of the liquid-passing channel 25, and the outlet pipe 32 connects the heat exchanger 41 to the outlet 13 of the liquid-passing channel 25. A driving member 43 is disposed on the outlet pipe 32. The driving member 43 drives the heat exchange medium in the outlet pipe 32 to flow to the heat exchanger 41. After heating the heat exchanger 41, the heat exchange medium flows through the inlet pipe 31 into the liquid-passing channel 25.

[0058] Reference Figures 1-2 In one possible implementation of this application, the liquid inlet pipe 31 includes a plurality of liquid inlet sub-pipes 311 that are connected one-to-one with the liquid flow channel 25. Each liquid inlet sub-pipe 311 is provided with an electronic water valve 44, and the controller 42 is used to control the opening degree of the electronic water valve 44.

[0059] The electronic water valve 44 is used to control the flow rate of the heat exchange medium in the corresponding liquid inlet pipe 311, thereby adjusting the flow rate of the heat exchange medium entering the heat exchanger 41 to adjust the heat value provided by the heat exchanger 41 to the outside.

[0060] For example, each electronic water valve 44 is electrically connected to the controller 42 and is also electrically connected via a second wiring harness 46.

[0061] Reference Figures 1-2 In one possible implementation of this application, the energy recovery device 100 further includes: a first temperature collector 51 and a second temperature collector 52. The first temperature collector 51 is disposed on the liquid outlet pipe 32 and is used to obtain the temperature of the heat exchange medium. The second temperature collector 52 is disposed on the heat exchanger 41 and is used to obtain the temperature of the heat exchanger 41.

[0062] The controller 42 controls the first temperature acquisition device 51 and the second temperature acquisition device 52 to collect the temperature of the heat exchange medium in the liquid pipe 32 and the surface temperature of the heat exchanger 41 respectively, based on the received external signals. It calculates the amount of heat that the heat exchanger 41 needs to absorb and the required flow rate of the heat exchange medium based on the received signal values. It controls the opening degree of multiple electronic water valves 44 to ensure the amount of heat absorbed, and controls the working power of the drive unit 43 to control the flow rate of the heat exchange medium. The energy recovery device 100 performs closed-loop control based on the input heat value and the output heat value.

[0063] For example, the first temperature sensor 51 is electrically connected to the controller 42 via the third wiring harness 53, and the second temperature sensor 52 is electrically connected to the controller 42 via the fourth wiring harness 54.

[0064] according to Figures 1-2 The usage process of the energy recovery device 100 of this application is described.

[0065] Step 1: When the vehicle is not started, the controller 42 controls the electronic water valve 44 to close the three liquid inlet pipes 311, the electronic water pump does not work, and the energy recovery device 100 only serves to reduce noise.

[0066] Step 2: When the vehicle is started and the vehicle controller has no heat input requirement, the controller 42 controls the electronic water valve 44 to close the three liquid inlet pipes 311, the electronic water pump does not work, and the energy recovery device 100 only serves to silence the noise.

[0067] Step 3: When the vehicle starts and the vehicle controller has a certain amount of heat demand input, the controller 42 receives the input signal and collects the temperature of the heat exchange medium and the surface temperature of the heat exchanger 41 through the first temperature acquisition device 51 and the second temperature acquisition device 52. Based on the three received signal values, the controller calculates the amount of heat that the heat exchanger 41 needs to absorb and the circulation flow rate of the heat exchange medium. The controller controls the opening degree of the three electronic water valves 44 to ensure the amount of heat absorbed and controls the working power of the electronic water pump to control the flow rate of the heat exchange medium. The energy recovery device 100 performs closed-loop control based on the input and output. The energy recovery device 100 plays the role of noise reduction and heat recovery, while the heat exchanger 41 plays the role of heat utilization.

[0068] Secondly, embodiments of this application provide a vehicle, including an energy recovery device 100.

[0069] The vehicle provided in this application embodiment includes the energy recovery device 100 provided in any of the above-mentioned embodiments, and therefore has the same technical effect. That is, the silencing cavity 11 in the exhaust pipe 10 can reduce the noise energy in the exhaust gas and achieve the silencing effect; the heat exchange module 20 in the exhaust pipe 10 can heat the heat exchange medium. The energy recovery device 100 can not only reduce the noise energy of the exhaust gas, but also utilize the high-temperature waste heat in the exhaust gas.

[0070] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application.
