Detailed Implementation

[0051] The embodiments of this disclosure are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. An engine 100 according to an embodiment of the first aspect of this disclosure is described below with reference to Figures 1-5. In the following description, the engine 100 is used in a vehicle 1000 as an example for detailed explanation.

[0052] As shown in Figure 1, the engine 100 according to a first aspect embodiment of the present disclosure includes a main body 1, an exhaust manifold 2, and a plurality of heat insulation components 3. In the description of the present disclosure, "a plurality of" means two or more.

[0053] Specifically, a heat loss component 11 is connected to the main body 1, an exhaust manifold 2 is located above the main body 1, at least a portion of the exhaust manifold 2 is opposite to the heat loss component 11, and at least one heat insulation element 3 is located between the exhaust manifold 2 and the heat loss component 11.

[0054] For example, in the examples of Figures 1 and 2, the four inlets of the exhaust manifold 2 are connected to the main body 1, and the peripheral and lower sides of the exhaust manifold 2 are opposite to the heat loss assembly 11. When the vehicle's power generation assembly 200 is operating, exhaust flows along the exhaust manifold 2, and the inner wall temperature of the exhaust manifold 2 can reach over 1000°C. The components around the exhaust manifold 2 face a harsh thermal environment, making them susceptible to damage. In this disclosure, the aforementioned susceptible components can be referred to as the heat loss assembly 11. With this arrangement, the heat insulation component 3 can shield the heat loss assembly 11 from heat radiation in the thermal environment, reducing the heat absorbed by the heat loss assembly 11 and avoiding the risk of heat damage. This allows the heat loss assembly 11 to operate normally for a longer period, extending the service life of the engine 100. Furthermore, the reasonable placement of the heat insulation component 3 allows it to shield and protect the heat loss assembly 11, improving the heat insulation effect and further protecting it from damage.

[0055] According to the engine 100 of this utility model, the heat insulation component 3 blocks heat radiation, reduces the heat received by the heat loss component 11, and avoids damage to the heat loss component 11, thereby enabling the heat loss component 11 to be used normally for a long time and extending the service life of the engine 100. In addition, the reasonable positioning of the heat insulation component 3 improves the heat insulation effect and further avoids damage to the heat loss component 11.

[0056] According to some embodiments of this disclosure, referring to Figures 2 and 3, the heat loss assembly 11 includes a cooling group 111, which includes a cooling pipe 1111 located above the main body 1. The cooling pipe 1111 is spaced apart from the exhaust manifold 2. A plurality of heat insulation elements 3 include a first heat insulation element 31 disposed between the exhaust manifold 2 and the cooling pipe 1111. The shape of the first heat insulation element 31 is adapted to the outer peripheral surface shape of the cooling pipe 1111. For example, in the examples of Figures 2 and 3, the cooling pipe 1111 and the exhaust manifold 2 are spaced apart along a first direction (the left-right direction as shown in Figure 2), the exhaust manifold 2 extends along a second direction (the front-back direction as shown in Figure 2), and the cooling pipe 1111 is located between the exhaust manifold 2 and the main body 1.

[0057] With this configuration, the first heat insulation component 31 can insulate the cooling pipe 1111, preventing heat loss from the exhaust manifold 2 and thus extending the service life of the cooling pipe 1111. Furthermore, the shape of the first heat insulation component 31 matches the outer circumferential shape of the cooling pipe 1111, facilitating a compact arrangement of the first heat insulation component 31 and the cooling pipe 1111, thereby reducing the space occupied by the first heat insulation component 31 and simplifying its placement. Moreover, it improves the shielding effect of the first heat insulation component 31 on the cooling pipe 1111, effectively shielding the heat source and heat hazard risk area, enhancing the insulation effect, and thus improving the protection of the cooling assembly 111, preventing damage to the cooling assembly 111. In addition, the first heat insulation component 31 has a compact and aesthetically pleasing structure, facilitating design and installation. The cooling assembly 111 includes an oil cooler 1112 and a thermostat 1113. A cooling pipe 1111 is located between the oil cooler 1112 and the thermostat 1113. The oil cooler 1112 is connected to the front end of the cooling pipe 1111, and the thermostat 1113 is connected to the rear end of the cooling pipe 1111. Thus, the cooling pipe 1111, oil cooler 1112, and thermostat 1113 work together to cool the engine 100. It should be noted that the minimum distance between the cooling assembly 111 and the exhaust manifold 2 is less than 10mm. For example, a minimum distance of 5mm poses a thermal risk, as the cooling pipe 1111 may experience excessively high coolant temperature and surface material failure.

[0058] According to some embodiments of this disclosure, referring to Figures 2 and 3, the edge of the first heat insulation member 31 away from the main body 1 has a flange 311, and the free end of the flange 311 extends in a direction away from the cooling pipe 1111. For example, in the examples of Figures 2 and 3, the upper end (i.e., the free end) of the flange 311 extends upward. With this configuration, the flange 311 can shield components such as the oil cooler 1112 and the thermostat 1113, reducing heat loss from the exhaust manifold 2 to the cooling pipe 1111, oil cooler 1112, and thermostat 1113, thereby extending the service life of the cooling assembly 111. Furthermore, it allows convective air to flow along the bottom or top of the first heat insulation member 31, avoiding the formation of a flow dead zone on the envelope surface, thus facilitating the smooth discharge of heat with the air and reducing the heat inside the engine 100. As shown by arrow A in Figure 1, the direction of airflow is indicated by arrow A.

[0059] According to some embodiments of this disclosure, the first heat insulation member 31 is connected to the main body 1. This arrangement enhances the connection stability of the first heat insulation member 31, prevents it from shaking, and thus reduces its vibration. It should be noted that the first heat insulation member 31 and the main body 1 can be directly connected or indirectly connected via other components. Multiple connection points are provided between the first heat insulation member 31 and the main body 1, further improving the stability of the first heat insulation member 31.

[0060] According to some embodiments of this disclosure, referring to Figures 1 and 4, the heat loss assembly 11 includes a turbocharger 112 connected to the outlet of the exhaust manifold 2, and the turbocharger 112 is located on one side of the main body 1 along a first direction (the left-right direction as shown in Figure 1). A plurality of heat insulation members 3 include a second heat insulation member 32, which covers the top surface of the turbocharger 112 and the side of the turbocharger 112 facing the exhaust manifold 2. For example, in the example of Figures 1 and 4, the inlet of the turbocharger 112 is connected to the outlet of the exhaust manifold 2, and the turbocharger 112 is located on the left side of the main body 1. With this configuration, the second heat insulation member 32 can insulate the turbocharger 112 from heat, preventing heat loss from the exhaust manifold 2 and thus extending the service life of the turbocharger 112. Furthermore, the second heat insulation member 32 can also shield and protect the turbocharger 112, providing significant heat insulation and preventing damage to the turbocharger 112.

[0061] According to some embodiments of this disclosure, referring to FIG4, the shape of the second heat insulation member 32 is adapted to the outer peripheral surface shape of the booster 112. This facilitates a compact arrangement of the second heat insulation member 32 and the booster 112, reducing the space occupied by the second heat insulation member 32 and simplifying its arrangement. Furthermore, the second heat insulation member 32 is designed to conform to the shape of the booster 112 volute, achieving complete shielding of the booster 112, effectively shielding the heat source and heat hazard risk area, providing good heat insulation, and further enhancing the protection of the booster 112, thus further avoiding the risk of heat damage to the booster 112. In addition, the second heat insulation member 32 has a compact and aesthetically pleasing structure, facilitating design and installation. The second heat insulation member 32 is connected to the booster 112, and multiple connection points are provided between the second heat insulation member 32 and the booster 112, thereby reducing the vibration of the second heat insulation member 32.

[0062] According to some embodiments of this disclosure, referring to FIG5, the exhaust manifold 2 includes a first body layer 21 and a second body layer 22 arranged radially spaced along the exhaust manifold 2, with the second body layer 22 disposed on the outer periphery of the first body layer 21. For example, in the example of FIG5, the second body layer 22 wraps around the first body layer 21. This arrangement allows the exhaust manifold 2 itself to achieve a heat insulation effect, i.e., heat insulation from the heat source, thus significantly reducing the heat generated by the exhaust manifold 2 on the surrounding environment and minimizing heat damage. Furthermore, the first body layer 21 and the second body layer 22 are consistent with the configuration of the exhaust manifold 2 itself, reducing the radiant temperature of the outer surface of the exhaust manifold 2 without requiring additional space or installation, resulting in a compact structure that is easy to install, thereby improving the installation efficiency of the exhaust manifold 2. Moreover, the arrangement of the first body layer 21 and the second body layer 22 also gives the exhaust manifold 2 good sound insulation and vibration isolation, improving the performance of the exhaust manifold 2.

[0063] Further, referring to Figure 5, a heat insulation layer 23 is provided between the first body layer 21 and the second body layer 22. For example, in the example of Figure 5, the exhaust manifold 2 has a sandwich-like heat insulation structure. With this configuration, the heat insulation layer 23 provides heat insulation, thereby further improving the heat insulation effect of the exhaust manifold 2 itself, reducing the heat damage caused by the exhaust manifold 2 to the heat loss component 11, and thus improving the service life of the engine 100. In addition, the heat insulation layer 23 also further improves the sound insulation and vibration damping effects, further improving the performance of the exhaust manifold 2. The heat insulation layer 23 can be a hydrogel component or a fiberglass component, but is not limited to these. It should be noted that the thicknesses of the first body layer 21, the second body layer 22, and the heat insulation layer 23 can be determined according to space and performance requirements.

[0064] According to some embodiments of this disclosure, the first body layer 21 and / or the second body layer 22 are metal components. For example, the arrangement of the first body layer 21 and the second body layer 22 includes the following situations: First, the first body layer 21 is a metal component. Second, the second body layer 22 is a metal component. Third, both the first body layer 21 and the second body layer 22 are metal components. This arrangement provides the metal components with good mechanical properties, thereby improving the structural strength of the first body layer 21 and the second body layer 22, preventing deformation of the first body layer 21 and the second body layer 22, and extending the service life of the exhaust manifold 2.

[0065] According to some embodiments of this disclosure, a heat-insulating coating 24 is applied to the outer peripheral surface of the second body layer 22, as shown in FIG5. Thus, the heat-insulating coating 24 further improves the heat insulation effect of the exhaust manifold 2 itself, that is, further reduces the temperature around the exhaust manifold 2, thereby improving the thermal environment of the heat loss component 11 and reducing the heat damage to the heat loss component 11. Specifically, the heat damage risk is determined by combining the temperature of the exhaust manifold 2, the temperature resistance requirements of the heat loss component 11, and the distance between them. The heat damage point is designed using a single heat-insulating element 3 that matches the contour of the heat loss component 11. The heat-insulating element 3 and the heat loss component 11 are arranged with several connection points that conform to the shape and are evenly distributed, resulting in stable and efficient heat insulation, and facilitating airflow without creating dead zones that lead to heat accumulation.

[0066] A power generation assembly 200 according to a second aspect embodiment of the present disclosure, referring to Figures 6 and 7, includes an engine 100 according to the first aspect embodiment of the present disclosure described above.

[0067] According to the power generation assembly 200 disclosed herein, by employing the aforementioned engine 100, heat insulation is provided from multiple angles of the heat source and heat transfer process, resulting in a significant heat insulation effect, avoiding damage to the heat loss component 11, thereby extending the service life of the power generation assembly 200.

[0068] According to some embodiments of the present disclosure, referring to Figures 6 and 8, the power generation assembly 200 further includes a motor 201 and a motor heat insulation member 202. The motor 201 is located on one side of the main body 1 of the engine 100 along a first direction (the left-right direction as shown in Figure 6), and the motor 201 is adjacent to the turbocharger 112 of the engine 100. The motor heat insulation member 202 at least covers the side surface of the motor 201 facing the turbocharger 112 and the side surface of the motor 201 away from the main body 1.

[0069] For example, in the examples of Figures 6, 8, and 9, the motor 201 is located on the left side of the main body 1 and in front of the turbocharger 112. Thus, the motor heat insulation component 202 shields the motor 201, effectively blocking heat from the turbocharger 112 and exhaust manifold 2, and isolating the motor 201 from heat transfer near heat sources. In other words, the motor heat insulation component 202 isolates the motor 201 from external heat radiation and convection, protecting the internal components of the motor 201, preventing heat loss, reducing the failure rate of the motor 201 during operation, and increasing its service life. Furthermore, a portion of the motor heat insulation component 202 covers the side of the motor 201 furthest from the main body 1 (i.e., the left side surface of the motor 201), preventing the heated motor 201 from dissipating heat to adjacent components after a certain period of operation, which is beneficial for the normal use of the motor 201 and its adjacent components.

[0070] According to some embodiments of this disclosure, referring to Figures 10 and 11, the power generation assembly 200 further includes an oil supply pump 203 connected to the side of the motor 201. The motor heat insulation member 202 has an extension 2021 located between the motor 201 and the main body 1, and the extension 2021 at least covers the side of the oil supply pump 203 facing the main body 1.

[0071] For example, in the examples of Figures 10 and 11, the oil supply pump 203 is located below the motor 201 and is connected to the lower side of the motor 201. The extension 2021 is located on the right side of the oil supply pump 203 and at least covers the right side of the oil supply pump 203. With this configuration, the motor heat insulation component 202, including the motor 201 and the oil supply pump 203, achieves full coverage of the heated surface, reducing the temperature of the environment where the oil supply pump 203 is located, meeting the heat insulation requirements of the oil supply pump 203, and thus extending the service life of the oil supply pump 203. Furthermore, the motor heat insulation component 202 is stamped with a full-edge covering to isolate the heat radiation and convection of external heat sources, thereby improving the heating conditions of the motor 201 and facilitating its long-term normal operation.

[0072] According to some embodiments of this disclosure, referring to FIG10, the portion of the motor heat insulation member 202 covering the side surface of the motor 201 facing the turbocharger 112 is formed as an arc surface. For example, in the example of FIG10, the side of the motor heat insulation member 202 located between the turbocharger 112 and the motor 201 is arc-shaped. This arrangement allows the motor heat insulation member 202 to be adapted to the shape of the motor 201, effectively saving assembly space and heat insulation material. It is easier to integrate while meeting heat insulation requirements, resulting in a more compact layout, reducing the space occupied by the motor heat insulation member 202, allowing for flexible arrangement, and increasing the heat insulation area of ​​the motor heat insulation member 202 on the motor 201, thereby improving the protection effect. In addition, it reduces the accumulation of heat on the aforementioned arc surface, improving eddy currents. Moreover, it plays a guiding role in the flow of surrounding heat.

[0073] Optionally, as shown in Figure 8, a catalytic converter 207 is connected to the end of the turbocharger 112 furthest from the exhaust manifold 2. The arc-shaped surface of the motor heat shield 202 partially encloses the rear side and bottom surface of the motor 201, effectively isolating heat from the turbocharger 112 and the catalytic converter 207, further preventing heat loss from the motor 201. The smooth outer surface of the arc-shaped surface of the motor heat shield 202 guides the heat transfer from the turbocharger 112. It should be noted that if the distance between the outlet flange of the exhaust manifold 2 and the connection surface between the motor 201 and the engine 100 is less than 10 mm, for example, 5 mm, there is a risk of failure for components (such as bolts and seals) at the connection surface between the motor 201 and the engine 100. If the minimum distance between the catalytic converter 207 and the side of the motor 201 is less than 30 mm, for example, 22 mm, there is a risk of heat loss. If the minimum distance between the turbocharger 112 and the side of the motor 201 is less than 30mm, for example, if the minimum distance is 25mm, there is a risk of heat loss.

[0074] According to some embodiments of this disclosure, referring to Figures 8 and 11, a plurality of first mounting holes 2022 are formed on the motor heat insulation component 202. The power generation assembly 200 further includes fasteners 204, which are respectively connected to the motor 201 through the plurality of first mounting holes 2022. Thus, by correspondingly engaging the plurality of fasteners 204 with the plurality of first mounting holes 2022, the motor heat insulation component 202 is connected to the motor 201, improving the stability of the motor heat insulation component 202 and reducing its vibration. This improves the rigidity of the motor heat insulation component 202 installation and enhances its noise, vibration, and harshness (NVH) characteristics, thereby improving its performance. Furthermore, the plurality of first mounting holes 2022 do not interfere with other components, and the simple structure ensures the vibration level of the heat insulation structure. It should be noted that the fasteners 204 can be bolts. The number and arrangement of the first mounting holes 2022 can be specifically set according to actual usage.

[0075] According to some embodiments of this disclosure, referring to FIG12, the power generation assembly 200 further includes an electrical control box 205 and an electrical control box heat insulation member 206. The electrical control box 205 is located on one side of the main body 1 of the engine 100 along a first direction (the left-right direction as shown in FIG12). The electrical control box 205 and the turbocharger 112 of the engine 100 are respectively connected to the two ends of the main body 1 along a second direction (the front-rear direction as shown in FIG12). The electrical control box heat insulation member 206 is located between the electrical control box 205 and the exhaust manifold 2 of the engine 100. For example, in the example of FIG12, the electrical control box 205 is located on the left side of the main body 1 of the engine 100, the electrical control box 205 is connected to the front end of the main body 1, and the turbocharger 112 of the engine 100 is connected to the rear end of the main body 1. With this configuration, the heat insulation component 206 of the electrical control box isolates the thermal radiation from the two exhaust manifolds from the electrical control box 205, reduces the degree of damage to the electrical control box 205, thereby improving the performance of the electrical control box 205 and extending its service life.

[0076] According to some embodiments of this disclosure, referring to Figures 13 and 14, the heat insulation component 206 of the electrical control box includes a heat insulation section 2061, a first fixing section 2062, and a second fixing section 2063. The heat insulation section 2061 is attached to the side of the electrical control box 205 facing the exhaust manifold 2. The first fixing section 2062 is connected to one side of the heat insulation section 2061 and extends along the thickness direction of the heat insulation section 2061. The first fixing section 2062 is connected to the top surface of the electrical control box 205. The second fixing section 2063 is connected to the other side of the heat insulation section 2061 and extends along the thickness direction of the heat insulation section 2061 in a direction away from the first fixing section 2062. The second fixing section 2063 is connected to the main body 1.

[0077] For example, in the example of Figure 13, the right end of the first fixing segment 2062 is connected to the upper side of the heat insulation segment 2061, and the left end of the first fixing segment 2062 extends away from the heat insulation segment 2061. The left end of the second fixing segment 2063 is connected to the lower side of the heat insulation segment 2061, and the right end of the second fixing segment 2063 extends away from the heat insulation segment 2061.

[0078] This design, while ensuring the insulation of the electrical control box insulation component 206, facilitates its connection to the electrical control box 205 via the first fixing section 2062 and to the main body 1 via the second fixing section 2063. This reduces the assembly difficulty of the insulation component 206, improves the installation efficiency of the generator assembly 200, enhances its installation stability, and reduces its vibration. Furthermore, the partially enclosed structure, based on the shape and position requirements of the electrical control box 205, ensures effective insulation while reducing overall layout space and avoiding material waste. Moreover, the insulation component 206 has a simple structure, is easy to manufacture, and improves production efficiency. The insulation section 2061 can be designed as a curved surface, thereby enhancing the structural strength of the insulation component 206 and improving its performance. Moreover, the increased heat exchange area of ​​the insulation section 2061 also has a flow guiding effect, thereby improving the insulation effect.

[0079] Further, referring to FIG13, at least one clearance hole 2062a is formed on the first fixing segment 2062. The clearance hole 2062a extends in a direction perpendicular to the plane of the heat insulation segment 2061, and the side of the clearance hole 2062a away from the heat insulation segment 2061 penetrates the edge of the first fixing segment 2062. For example, in the example of FIG13, the clearance hole 2062a extends in a left-right direction. The right side of the clearance hole 2062a extends to the upper edge of the heat insulation segment 2061, and the left side of the clearance hole 2062a extends to the left edge of the first fixing segment 2062. The aforementioned left side of the clearance hole 2062a penetrates the left edge of the first fixing segment 2062. With this design, the clearance hole 2062a can avoid contact with the bolts on the electrical control box 205, which facilitates the installation of the electrical control box insulation component 206 and the electrical control box 205. It also reduces the distance between the insulation section 2061 of the electrical control box insulation component 206 and the electrical control box 205, making the electrical control box insulation component 206 compact and flexible in its arrangement.

[0080] According to some embodiments of this disclosure, referring to FIG14, a plurality of second mounting holes 2062b are formed on the first fixing segment 2062, and a plurality of clearance holes 2062a are formed. The plurality of clearance holes 2062a and the plurality of second mounting holes 2062b are arranged alternately and at intervals along the second direction (the front-back direction shown in FIG14); and / or, a plurality of third mounting holes 2063a are formed on the second fixing segment 2063, and the plurality of third mounting holes 2063a are arranged at intervals along the second direction.

[0081] For example, the first fixing segment 2062 and the second fixing segment 2063 can be configured in the following ways: First, the first fixing segment 2062 has multiple second mounting holes 2062b and multiple clearance holes 2062a, with the clearance holes 2062a and the multiple second mounting holes 2062b arranged alternately along the second direction. Second, the second fixing segment 2063 has multiple third mounting holes 2063a, with the multiple third mounting holes 2063a arranged at intervals along the second direction. Third, the first fixing segment 2062 has multiple second mounting holes 2062b and multiple clearance holes 2062a, with the clearance holes 2062a and the multiple second mounting holes 2062b arranged alternately along the second direction, while the second fixing segment 2063 has multiple third mounting holes 2063a, with the multiple third mounting holes 2063a arranged at intervals along the second direction (as shown in Figure 13).

[0082] This configuration increases the connection points between the control box insulation 206 and the control box 205 through multiple second mounting holes 2062b, and increases the connection points between the control box insulation 206 and the main body 1 of the generator 201 through multiple third mounting holes 2063a. This further improves the connection stability between the control box insulation 206 and the control box 205, and between the control box insulation 206 and the main body 1 of the generator 201, thus enhancing the operational stability of the control box insulation 206. This reduces the possibility of fatigue fracture and improves NVH performance. Furthermore, the multiple second mounting holes 2062b do not interfere with other components, and the simple structure ensures the vibration level of the insulation structure.

[0083] According to some embodiments of this disclosure, referring to FIG13, the free end of the second fixed section 2063 has a flange 2063b. The flange 2063b extends along the thickness direction of the second fixed section 2063 in a direction away from the heat insulation section 2061. The free end face of the flange 2063b is on the same plane as the plane where the inlet of the exhaust manifold 2 is located. For example, in the example of FIG13, the flange 2063b is located at the right end of the second fixed section 2063. The flange 2063b extends downward, and the plane where the lower end face of the flange 2063b (i.e., the free end face of the flange 2063b) is located is on the same plane as the plane where the inlet of the exhaust manifold 2 is located. This arrangement allows the heat insulation component 206 of the electrical control box to completely shield the heated area of ​​the electrical control box 205, thereby improving the heat insulation performance of the heat insulation component 206 of the electrical control box and effectively reducing the heat exposure of the electrical control box 205. In addition, the rigidity of the electrical control box insulation component 206 has been enhanced, extending its service life. It should be noted that the lower end face of the flange 2063b is on the same plane as the inlet flange of the exhaust manifold 2.

[0084] Optionally, the electrical control box insulation component 206 is a one-piece molded part. This improves the structural strength of the insulation component 206, preventing fatigue fracture under strong vibration and extending its service life. The inner, middle, and outer layers of the insulation component 206 are stamped using a fully enclosed edge method, with the middle layer located between the inner and outer layers. The inner and outer layers can be metal, while the middle layer can be an air layer or insulation component 3, further enhancing the insulation effect. The insulation component 206 undergoes electrophoretic treatment, resulting in a smooth surface and effectively reducing the impact of radiative heat transfer on the electrical control box 205. It should be noted that the minimum distance between the front end of the exhaust manifold 2 and the right side of the electrical control box 205 is less than 70mm. For example, a minimum distance of 62mm poses a risk of heat damage to the electrical control box 205.

[0086] According to the vehicle 1000 disclosed herein, by employing the aforementioned engine 100 or power generation assembly 200, the heat loss of the vehicle 1000 is reduced, and the service life of the vehicle 1000 is extended.
