[0032] The features and exemplary embodiments of various aspects of this application will now be described in detail. Numerous specific details are set forth in the following detailed description to provide a comprehensive understanding of this application. However, it will be apparent to those skilled in the art that this application can be implemented without requiring some of these specific details. The following description of embodiments is merely intended to provide a better understanding of this application by illustrating examples. In the accompanying drawings and the following description, at least some well-known structures and techniques are not shown to avoid unnecessarily obscuring the application; and, for clarity, the dimensions of some structures may be exaggerated. Furthermore, the features, structures, or characteristics described below can be combined in any suitable manner in one or more embodiments.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] The intercooler is a crucial component in turbocharged or supercharged engine systems. During air compression, turbochargers and superchargers raise the air temperature. High-temperature intake air has a lower density and relatively less oxygen, leading to decreased combustion efficiency. The intercooler cools the intake air, lowering its temperature and increasing its density, thus increasing the oxygen content per unit volume. Because the cooled intake air is denser and contains more oxygen, combustion is more complete, generating greater thrust and improving engine torque and power output.

[0036] Existing water-to-intercooler systems lack fixed piping points connecting the intercooler and radiator. As the vehicle vibrates during movement, this piping can easily interfere with the front crossbeam. To better understand this application, the following section combines... Figures 1 to 6 The intercooler, engine assembly, and vehicle of the embodiments of this application are described in detail.

[0037] Figure 1 This is one of the structural diagrams of an intercooler provided in the embodiments of this application. Figure 2 This is a second schematic diagram of an intercooler provided in an embodiment of this application. Figure 3 This is a schematic diagram of the exhaust section of an intercooler provided in an embodiment of this application.

[0038] Please refer to the following: Figures 1 to 3For easy distinction, Figure 3 The structure of the intercooler 000 is represented by dashed lines, while the structure of other engine components is represented by dashed lines. An embodiment of the first aspect of this application provides an intercooler 000, which includes a wall portion 100 and a first limiting portion 200. The wall portion 100 encloses a chamber 110 and two drain outlets 120 communicating with the chamber 110. The wall portion 100 includes a top wall 101 and a bottom wall 102 disposed opposite to each other, and a side wall 103 connecting the top wall 101 and the bottom wall 102. The two drain outlets 120 are spaced apart on the side wall 103 near the bottom wall 102. The first limiting portion 200 is located on the side wall 103 near the top wall 101, and the first limiting portion 200 is used to limit the engine pipe 430 communicating with the drain outlets 120.

[0039] In the embodiment provided in the first aspect of this application, the intercooler 000 includes a wall portion 100 and a first limiting portion 200. The wall portion 100 is used to arrange the various components of the intercooler 000 and enclose to form a chamber 110 and two drain ports 120 communicating with the chamber 110. The chamber 110 is used to hold coolant for heat exchange, and the drain ports 120 are used to drain coolant into or out of the chamber 110. The wall portion 100 includes a top wall 101 and a bottom wall 102 disposed opposite to each other, and a side wall 103 connecting the top wall 101 and the bottom wall 102. The two drain ports 120 are spaced apart on the side wall 103 near the bottom wall 102, which reduces the flow resistance of coolant, facilitates the drainage of coolant, and reduces the power required for heat exchange. The first limiting part 200 is used to limit the engine pipe 430 connected to the drain outlet 120. The first limiting part 200 is located on the side wall 103 near the top wall 101, thereby limiting the engine pipe 430 from the end near the drain outlet 120 to the limiting point on the side wall 103. The first limiting part 200 and the drain outlet 120 are spaced apart on both sides of the side wall 103, which can make the length of this section of pipe longer, so that the engine pipe 430 is better limited to the side wall 103 and less likely to interfere with other components. By fixing the engine pipe 430, the potential interference to other engine components caused by the relative displacement of the engine pipe 430 due to vibration during use is reduced, ensuring the normal operation of the intercooler 000.

[0040] Optionally, the intercooler 000 provided in this application embodiment can be a water-to-air intercooler, which has higher cooling efficiency and is suitable for vehicles under various driving conditions.

[0041] Optionally, there are two drain outlets 120 and two engine pipes 430. Each engine pipe 430 is connected to each drain outlet 120 to achieve heat exchange of the generator.

[0042] Optionally, the coolant includes at least one of water and antifreeze. Water and antifreeze provide good cooling performance and antifreeze protection to ensure the cooling performance and system reliability of the intercooler 000.

[0043] Optionally, the sidewall 103 may be provided with reinforcing ribs 140, which can enhance the mechanical strength of the intercooler 000.

[0044] Optionally, the intercooler 000 also includes an air inlet 150 and an air outlet 160 communicating with the chamber 110. High-temperature, high-pressure intake air from the turbocharger or supercharger enters the intercooler through the air inlet 150, is cooled by heat exchange, and is then delivered to the engine's intake manifold or combustion chamber through the air outlet 160.

[0045] Optionally, the intercooler 000 also includes a Venturi tube interface 170 communicating with the chamber 110. The Venturi tube interface 170 is used to connect a Venturi tube for measuring the fluid (liquid or gas) flow rate and can monitor the coolant status in real time.

[0046] In some alternative embodiments, the intercooler 000 also includes two interface pipes 130, one end of each interface pipe 130 being connected to a drain outlet 120, and the other end extending toward the top wall 101 and used to communicate with the engine pipe 430.

[0047] In these alternative embodiments, the interface conduit 130 extends from the drain port 120 of the side wall 103 toward the top wall 101, facilitating the connection of the engine pipe 430, enhancing the stability of the connection with the engine pipe 430, reducing the risk of loosening due to vibration or external force, and improving the sealing of the connection, thus mitigating the problem of coolant leakage.

[0048] In some optional embodiments, the sidewall 103 includes two first sub-walls 103a spaced apart along a first direction X and two second sub-walls 103b spaced apart along a second direction Y. The two first sub-walls 103a and two second sub-walls 103b are connected end to end. Two drain outlets 120 are disposed on one of the two second sub-walls 103b. A first limiting part 200 is located on one of the two first sub-walls 103a, and the first limiting part 200 is located on the side of the first sub-wall 103a closer to the second sub-wall 103b. The first direction X and the second direction Y intersect.

[0049] Optionally, the first limiting part 200 can be disposed on one of the two second sub-walls 103b. The installation position of the first limiting part 200 is not specifically limited and depends on the specific installation situation. For ease of understanding, this application embodiment is described with the first limiting part 200 disposed on the second sub-wall 103b near the outlet 122. In these optional embodiments, the two first sub-walls 103a and the two second sub-walls 103b are connected end to end to form a chamber 110 for containing coolant. The two drain outlets 120 are disposed on one of the two second sub-walls 103b, and the engine pipe 430 is connected to the same second sub-wall 103b, making full use of the space of the second sub-wall 103b, making the overall structure more compact, improving space utilization, facilitating the simultaneous fixation of the first limiting part 200 on the two engine pipes 430, and simplifying the installation and maintenance process.

[0050] In addition, the first limiting part 200 is located on the side of the first sub-wall 103a near the second sub-wall 103b, which can fix the engine pipe 430 at the boundary of the first sub-wall 103a, reducing the problem of the engine pipe 430 vibrating and displacing, thus interfering with the internal structure of the engine located on the side of the first sub-wall 103a.

[0051] In some optional embodiments, one of the two drain outlets 120 is a water inlet 121 and the other is a water outlet 122. The water inlet 121 and the water outlet 122 are spaced apart along the first direction X. The intercooler 000 also includes a second limiting part 300. The second limiting part 300 is located on the side of the first sub-wall 103a near the top wall 101 and the water outlet 122. The second limiting part 300 and the first limiting part 200 are spaced apart along the second direction Y. The second limiting part 300 is used to fix the engine wiring harness 440.

[0052] In these optional embodiments, the inlet 121 and outlet 122 are spaced apart along the first direction X to facilitate the arrangement of the engine piping 430. The second limiting part 300 is used to fix the engine wiring harness 440, reducing the possibility of the engine wiring harness 440 being displaced or damaged due to vibration or other external forces during vehicle operation. The second limiting part 300 and the first limiting part 200 are spaced apart along the second direction Y, making full use of the space of the first sub-wall 103a and making the overall structure more compact.

[0053] Optionally, the first limiting portion 200 and / or the second limiting portion 300 and the wall portion 100 are integrally formed, for example, the first limiting portion 200 and / or the second limiting portion 300 and the first sub-wall 103a are integrally formed, thereby facilitating production casting.

[0054] Optionally, the first limiting part 200 may be provided with a first fixing hole 210 extending along the second direction Y, and the engine pipe 430 may be snapped into the first fixing hole 210 for easy disassembly and assembly.

[0055] Optionally, the second limiting part 300 may be provided with a second fixing hole 310 extending along the second direction Y, and the engine wiring harness 440 may be snapped into the second fixing hole 310 for easy disassembly and assembly.

[0056] like Figures 1 to 3 As shown, an embodiment of the second aspect of this application provides an engine assembly 400, which includes a housing 410, a radiator (not shown), an intercooler 000, and engine piping 430. The radiator is used for heat dissipation. The intercooler 000 and the radiator are spaced apart along a second direction Y on both sides of the housing 410. One of the two drain outlets 120 is a water inlet 121, and the other is a water outlet 122, which are spaced apart along a first direction X. Of the two engine piping 430, the engine piping 430 connected to the water inlet 121 is the water inlet pipe 431, and the engine piping 430 connected to the water outlet 122 is the water outlet pipe 432. One end of each engine piping 430 is connected to the radiator, and the other end of each engine piping 430 is connected to the water inlet 121 and the water outlet 122, respectively. The engine piping 430 is arranged around the housing 410.

[0057] In the embodiment provided in the second aspect of this application, the engine assembly 400 includes a housing 410, a radiator, an intercooler 000, and engine piping 430. The housing 410 is used to house and protect engine components, and the radiator is used for heat dissipation. The intercooler 000 and the radiator are spaced apart on both sides of the housing 410 along a second direction Y, and the engine piping 430 is arranged around the housing 410 to ensure the length of the coolant flow path, allowing sufficient time for heat exchange. The coolant can be cooled between the radiator and the intercooler 000, thereby keeping the engine at a suitable operating temperature. One of the two drain outlets 120 is an inlet 121, and the other is an outlet 122. The inlet 121 and the outlet 122 are spaced apart along a first direction X to facilitate the arrangement of the engine piping 430. The two engine piping 430 connect the radiator and the intercooler 000 for heat exchange. In the engine assembly 400 provided in this embodiment, a first limiting part 200 is used to limit the engine pipe 430 connected to the drain outlet 120. The first limiting part 200 is located on the side wall 103 near the top wall 101, so that the engine pipe 430 is limited to the side wall 103 from the end near the outlet 122 to the limiting point. The first limiting part 200 and the drain outlet 120 are spaced apart on both sides of the side wall 103, which can make the length of this section of pipe longer, so that the engine pipe 430 is better limited to the side wall 103 and is less likely to interfere with other components. By fixing the engine pipe 430, the potential interference to other engine components caused by the relative displacement of the engine pipe 430 due to vibration during use is reduced, ensuring the normal operation of the engine assembly 400.

[0058] In some alternative embodiments, such as Figure 1 and Figures 4 to 5 As shown, the intercooler 000 also includes a pipe retainer 433, with the inlet pipe 431 and the outlet pipe 432 fitted onto the same pipe retainer 433. The inlet pipe 431 and the outlet pipe 432 are detachably connected to the first limiting part 200 through the pipe retainer 433.

[0059] In these alternative embodiments, the inlet pipe 431 and the outlet pipe 432 are fitted onto the same pipe retainer 433, which improves the problem of the inlet pipe 431 and the outlet pipe 432 getting tangled. The inlet pipe 431 and the outlet pipe 432 are detachably connected to the first limiting part 200 through the pipe retainer 433, which facilitates disassembly and assembly.

[0060] Optionally, the pipe clamp 433 can be a water pipe fixing clamp, which has a simple structure and low cost.

[0061] In some alternative embodiments, such as Figures 1 to 3The first limiting part 200 is located on the side wall 103 near the outlet 122. The connection between the first limiting part 200 and the engine pipe 430 is the installation point 434. The inlet pipe 431 and the outlet pipe 432 are arranged side by side along the third direction Z at the installation point. The outlet pipe 432 is located on the side of the inlet pipe 431 near the drain outlet 120. At least part of the inlet pipe 431 is located on the side of the installation point 434 along the third direction Z near the bottom wall 102. The first direction X, the second direction Y, and the third direction Z intersect each other.

[0062] In these alternative embodiments, two engine pipes 430 are arranged side-by-side along the third direction Z at mounting point 434, with the outlet pipe 432 located on the side of the inlet pipe 431 near the drain outlet 120. This fixes the relative position of the outlet pipe 432 between the inlet pipes 431, reducing vibration and friction between them and mitigating the problem of the inlet and outlet pipes 431 becoming entangled and affecting cooling efficiency. At least a portion of the inlet pipe 431 is located on the side of the mounting point 434 along the third direction Z near the bottom wall 102, ensuring that the projection of the inlet pipe 431 onto the second wall portion 100 is as much as possible within the second wall portion 100, thereby reducing the possibility of interference between the engine and other vehicle components along the third direction Z.

[0063] In some optional embodiments, the engine assembly 400 further includes a main controller (not shown) and an engine wiring harness 440, and the intercooler 000 further includes a sub-controller (not shown). The main controller and the sub-controller are connected through the engine wiring harness 440, and both the main controller and the sub-controller are located on the side of the housing 410 near the outlet 122. The engine wiring harness 440 is connected to the intercooler 000 through a second limiting part 300, which is located on the side wall 103 near the outlet 122.

[0064] In these optional embodiments, the main controller is the core of the entire engine control system, responsible for coordinating and managing various operating parameters of the engine and controlling various engine components to ensure efficient and stable engine operation. Sub-controllers are used to control the intercooler 000. Centralizing the main controller and sub-controllers in the same area simplifies wiring, reduces harness length, and lowers the failure rate. The second limiting part 300 is located on the side wall 103 near the outlet 122, adapting to the arrangement area of ​​the engine wiring harness 440, facilitating the fixation of the engine wiring harness 440.

[0065] In some alternative embodiments, the engine assembly 400 further includes a wiring harness retainer 441 for mounting the engine wiring harness 440 and for detachably connecting it to the second limiting portion 300.

[0066] In these alternative embodiments, the detachable connection makes the installation and maintenance of the engine wiring harness 440 simpler and faster, reducing installation time and difficulty, and lowering labor costs.

[0067] Optionally, the wiring harness retainer 441 can be a wiring harness retaining clip, and the engine wiring harness 440 can be attached to the second limiting part 300 by the wiring harness retaining clip, which is low in cost and easy to install and remove.

[0068] Optionally, the engine assembly 400 also includes a mounting bracket 450. One end of the mounting bracket 450 is disposed on two second sub-walls 103b opposite to the drain outlet 120 along the second direction Y, and the other end of the mounting bracket 450 is fixedly connected to the housing 410. The intercooler 000 is fixed to the engine housing 410 by the mounting bracket 450, which facilitates the installation and removal of the intercooler 000.

[0069] Optionally, the intercooler 000 also includes bolt mounting holes 180, through which the intercooler 000 can be mounted on the engine housing 410, facilitating the installation and removal of the intercooler 000.

The engine assembly 400 includes an intercooler 000 as described above. The front crossbeam 500 and the top wall 101 are spaced apart along the third direction Z, and the first limiting part 200 is located on the side wall 103 near the front crossbeam 500. The minimum distance between the front crossbeam 500 and the intercooler 000 is no more than 25mm.

[0071] In the embodiment provided in the third aspect of this application, the vehicle includes a front crossbeam 500 and an engine assembly 400. The front crossbeam 500 is used to strengthen the vehicle body structure, improve vehicle stability, and enhance safety. The engine assembly 400 includes an intercooler 000 as described above. The front crossbeam 500 and the top wall 101 are spaced apart along a third direction Z, and the first limiting portion 200 is located on the side wall 103 near the front crossbeam 500 to mitigate the problem of collision interference between the top wall 101 and the front crossbeam 500, which affects the service life. The minimum distance between the front crossbeam 500 and the intercooler 000 can be 25mm to mitigate the problem of vibration of the engine assembly 400 and displacement of the engine pipes 430 and other components during vehicle operation, which could cause interference with the front crossbeam 500, thereby improving the service life of the vehicle. In the vehicle provided in this application embodiment, the first limiting part 200 is used to limit the engine pipe 430 connected to the drain outlet 120. The first limiting part 200 is located on the side of the side wall 103 near the top wall 101, thereby limiting the engine pipe 430 from the end near the water outlet 432 to the limiting point on the side wall 103. The first limiting part 200 and the drain outlet 120 are spaced apart on both sides of the side wall 103, which can make the length of this pipe longer, thereby better limiting the engine pipe 430 to the side wall 103 and making it less likely to interfere with other components. By fixing the engine pipe 430, the potential interference to other engine components caused by the relative displacement of the engine pipe 430 due to vibration during use is reduced, ensuring the normal operation of the vehicle. Although this application has been described with reference to preferred embodiments, various modifications can be made to it and equivalent components can be replaced without departing from the scope of this application. In particular, as long as there is no structural conflict, the various technical features mentioned in the various embodiments can be combined in any way. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
