Description

Technical Field

[0001] This utility model belongs to the field of vehicle component technology, and specifically relates to an intercooler and a car having the intercooler. Background Technology

[0002] For turbocharged engines, an intercooler is generally required to reduce the temperature of the high-temperature gas after turbocharging. When air passes through the compressor of the turbocharger, its temperature rises significantly and its density decreases accordingly. The intercooler's role is to cool this air. If an intercooler is missing and the high-temperature turbocharged air enters the engine directly, it will lead to a reduction in intake air volume and engine power, as well as poor combustion, causing problems such as knocking and pre-ignition.

[0003] Traditional intercoolers typically use air cooling, i.e., air-cooled intercoolers. They are installed at the front of the vehicle along with the air conditioning system condenser and engine coolant radiator, relying on the airflow generated by the vehicle's oncoming airflow and the air intake fan for cooling. Some current models also use water-cooled intercoolers, where the high-temperature, pressurized gas is cooled by coolant, which is then further cooled by an additional radiator at the front. Although the two types of intercoolers use different media to directly cool the high-temperature gas, both ultimately rely on the airflow at the front of the vehicle for heat dissipation. In high-temperature environments, when the vehicle is traveling at low speeds or in traffic jams, insufficient airflow can lead to inadequate intercooler cooling and excessively high intake air temperatures. Both types of intercoolers can only cool the intake air to near ambient temperature at their maximum capacity, and are highly susceptible to environmental conditions.

[0004] In addition, when a vehicle accelerates rapidly or climbs a hill, the engine load increases instantaneously, and the turbocharger outlet temperature also rises rapidly. At this time, whether it is an air-cooled intercooler or a water-cooled intercooler, the sensible heat of the cooling medium cannot absorb the heat quickly. It needs to flow through the cooling medium to effectively cool down. Therefore, there will be a significant cooling delay. The short-term high temperature shock of the intake air temperature will also lead to a reduction in intake volume and deterioration of combustion. Utility Model Content

[0005] The purpose of this invention is to solve the problems of significant cooling delay in the intercooler in the prior art, and the high temperature shock of short-term intake air temperature that leads to reduced intake air volume and deterioration of combustion.

[0006] To solve the above-mentioned technical problems, this utility model discloses an intercooler, comprising: a hollow shell; a connecting bracket fixedly connected to the inside of the shell; and multiple air intake pipes, which are arranged side by side and spaced apart inside the connecting bracket. Some or all of the multiple air intake pipes are connected to the connecting bracket to achieve heat transfer and together with the connecting bracket, define a cavity. Each cavity is filled with a solid-liquid phase change material, and the solid-liquid phase change material covers the outer periphery of the corresponding air intake pipe.

[0007] The above technical solution involves coating the outer periphery of the intake pipe with a solid-liquid phase change material. During short-term high-temperature gas impacts inside the intake pipe, the material absorbs latent heat through phase change to cool the intake air, preventing temperature surges and ensuring the engine's intake air volume requirements and normal combustion. Furthermore, multiple intake pipes are arranged side-by-side and fixedly installed inside a connecting bracket. Some or all of the intake pipes are connected to the connecting bracket for heat transfer. The connecting bracket serves both to fix the intake pipes and to conduct heat, allowing some of the intake air heat from the pipes to be transferred to its periphery, maintaining the intake air temperature. Additionally, some or all of the intake pipes and the connecting bracket together form a cavity, each filled with the solid-liquid phase change material. This material remains around the intake pipe even after melting, ensuring efficient heat exchange.

[0008] According to another specific embodiment of the present invention, the intercooler disclosed in this embodiment has a connecting bracket in the shape of a grid and includes multiple connecting grids arranged in sequence. Each connecting grid has a corresponding air intake pipe inside, and the air intake pipe is fixedly connected to the connecting grid to achieve heat transfer.

[0009] Using the above technical solution, the connecting bracket is mesh-like, with a robust structure that ensures the stability of the connection between multiple air intake pipes. Each connecting mesh contains a corresponding air intake pipe, ensuring uniform heat transfer efficiency for each air intake pipe through its corresponding connecting mesh.

[0010] According to another specific embodiment of the present invention, the intercooler disclosed in this embodiment of the present invention includes a ring-shaped frame and a skeleton disposed inside the frame, wherein the outer edge of the skeleton is fixedly connected to the inner surface of the frame, and the inner edge of the skeleton is fixedly connected to the corresponding intake pipe to realize heat transfer.

[0011] Using the above technical solution, part of the intake heat from the intake pipe is transferred to the frame through the skeleton, and then to the periphery of the connecting bracket to achieve heat transfer.

[0012] According to another specific embodiment of the present invention, the intercooler disclosed in this embodiment includes a frame comprising a plurality of connecting plates spaced apart along the outer periphery of the corresponding intake pipe. One end of each connecting plate is fixedly connected to the frame, and the other end is fixedly connected to the outer wall of the corresponding intake pipe.

[0013] Using the above technical solution, part of the intake heat from the intake pipe is transferred to the frame through multiple connecting plates, and then transferred to the periphery of the connecting bracket to achieve heat transfer.

[0014] According to another specific embodiment of the present invention, the intercooler disclosed in this embodiment has multiple connecting grids arranged in an array and multiple intake pipes arranged in an array.

[0015] Using the above technical solution, multiple connecting grids and multiple air intake pipes are arranged in an array to ensure the uniformity of heat exchange efficiency of each air intake pipe.

[0016] According to another specific embodiment of the present invention, the intercooler disclosed in this embodiment has a coolant channel formed between the housing and the connecting bracket for the flow of coolant.

[0017] By adopting the above technical solution, the heat of the incoming air transferred to the periphery of the connecting bracket can be carried away by the circulating coolant.

[0018] According to another specific embodiment of the present invention, the intercooler disclosed in the embodiment of the present invention has one or more sets of heat exchange fins arranged in the coolant channel, and one or more sets of heat exchange fins are fixed to the outer periphery of the connecting bracket; each set of heat exchange fins in the one or more sets of heat exchange fins includes one heat exchange fin or multiple heat exchange fins arranged in sequence at intervals.

[0019] By adopting the above technical solution, the heat of the intake air around the connecting bracket can be transferred to the heat exchange fins, and further exchanged with the heat exchange fins through the coolant in the coolant channel to remove the heat transferred to the heat exchange fins and maintain the intake air temperature.

[0020] According to another specific embodiment of the present invention, the intercooler disclosed in this embodiment has one or more cooling plates fixedly arranged on the outer periphery of the connecting bracket, and one or more sets of heat exchange fins located on the outer periphery of one or more cooling plates and fixed to the outer periphery of the connecting bracket by corresponding cooling plates. The cooling plates are semiconductor cooling plates.

[0021] Using the above technical solution, the heat from the intake air transferred to the periphery of the connecting bracket can be transferred to the cooling plate. The cooling plate is a semiconductor cooling plate, which can absorb some heat after being powered on. Furthermore, as a semiconductor cooling plate, its cooling temperature is not limited by the ambient temperature, achieving a cooling effect lower than traditional air-cooled or water-cooled intercoolers. The heat from the cooling plate can also be transferred to the heat exchange fins, where heat exchange fins exchange heat with the coolant flowing through the coolant channels to remove the heat transferred to the fins. Thus, the intake air temperature is maintained through the combined action of the cooling plate and the coolant.

[0022] According to another specific embodiment of the present invention, in the intercooler disclosed in the embodiment of the present invention, the two ends of each heat exchange fin in one or more sets of heat exchange fins are respectively fixed to the corresponding cooling plate and the shell, and the connecting bracket is fixedly connected to the inside of the shell through one or more cooling plates and one or more sets of heat exchange fins.

[0023] By adopting the above technical solution, the two ends of the heat exchange fins are fixed to the corresponding cooling plate and the shell respectively, which can increase the heat exchange area with the coolant flowing through the coolant channel and improve the heat exchange efficiency.

[0024] According to another specific embodiment of the present invention, the intercooler disclosed in this embodiment has a solid-liquid phase change material phase change temperature of 30-45°C.

[0025] Using the above technical solution, the phase change temperature of the solid-liquid phase change material is 30-45℃, which is consistent with the ideal intake air temperature of the engine. Thus, when subjected to short-term high-temperature gas impact, the material absorbs latent heat through phase change to cool the intake air, so that the intake air temperature reaches the ideal intake air temperature.

[0026] This utility model also discloses an automobile, including the aforementioned intercooler.

[0027] The beneficial effects of this utility model are as follows:

[0028] This invention provides an intercooler and an automobile. The intercooler includes a hollow shell, a connecting bracket fixedly connected to the inside of the shell, and multiple intake pipes. A solid-liquid phase change material is coated on the outer periphery of the corresponding intake pipe. When subjected to short-term impact from high-temperature internal gas, the material absorbs latent heat through phase change to cool the intake air, ensuring the engine's intake air volume requirements and normal combustion. Furthermore, the multiple intake pipes are arranged side-by-side and fixedly positioned inside the connecting bracket, and some or all of the intake pipes are connected to the connecting bracket to achieve heat transfer. The connecting bracket not only fixes the intake pipes but also acts as a heat-conducting bracket, allowing some of the intake air heat from the intake pipes to be transferred to the periphery of the connecting bracket, maintaining the intake air temperature. Even further, some or all of the multiple intake pipes and the connecting bracket together define a cavity, each cavity filled with a solid-liquid phase change material. Even after the phase change material melts, it remains around the intake pipe, ensuring heat exchange efficiency. Attached Figure Description

[0034] For turbocharged engines, an intercooler is generally required to reduce the temperature of the high-temperature gas after turbocharging. When air passes through the compressor of the turbocharger, its temperature rises significantly and its density decreases accordingly. The intercooler's role is to cool this air. If an intercooler is missing and the high-temperature turbocharged air enters the engine directly, it will lead to a reduction in intake air volume and engine power, as well as poor combustion, causing problems such as knocking and pre-ignition.

[0035] Traditional intercoolers typically use air cooling, i.e., air-cooled intercoolers. They are installed at the front of the vehicle along with the air conditioning system condenser and engine coolant radiator, relying on the airflow generated by the vehicle's oncoming airflow and the air intake fan for cooling. Some current models also use water-cooled intercoolers, where the high-temperature, pressurized gas is cooled by coolant, which is then further cooled by an additional radiator at the front. Although the two types of intercoolers use different media to directly cool the high-temperature gas, both ultimately rely on the airflow at the front of the vehicle for heat dissipation. In high-temperature environments, when the vehicle is traveling at low speeds or in traffic jams, insufficient airflow can lead to inadequate intercooler cooling and excessively high intake air temperatures. Both types of intercoolers can only cool the intake air to near ambient temperature at their maximum capacity, and are highly susceptible to environmental conditions.

[0036] In addition, when a vehicle accelerates rapidly or climbs a hill, the engine load increases instantaneously, and the turbocharger outlet temperature also rises rapidly. At this time, whether it is an air-cooled intercooler or a water-cooled intercooler, the sensible heat of the cooling medium cannot absorb the heat quickly. It needs to flow through the cooling medium to effectively cool down. Therefore, there will be a significant cooling delay. The short-term high temperature shock of the intake air temperature will also lead to a reduction in intake volume and deterioration of combustion.

[0037] To address the aforementioned technical problems, this utility model provides an intercooler and an automobile. The intercooler has multiple air channels arranged internally as intake pipes. A bracket connects these air channels, serving two purposes: firstly, to fix the air channels, and secondly, to create a cavity that accommodates a phase change material. Even after the phase change material melts, it remains around the air channels, ensuring heat exchange efficiency. This bracket is made of a high thermal conductivity material (such as copper or aluminum) and is tightly connected to the outer wall of the air channels, functioning as heat-conducting fins to transfer intake heat to the bracket's periphery.

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0039] Example 1

[0040] This utility model provides an intercooler, such as Figures 1-3 As shown, it includes: a hollow shell 100; a connecting bracket 200, which is fixedly connected to the inside of the shell 100; and multiple air intake pipes 300, which are fixedly arranged side by side at intervals inside the connecting bracket 200. Some or all of the multiple air intake pipes 300 are connected to the connecting bracket 200 to achieve heat transfer, and together with the connecting bracket 200, they define a cavity 400. Each cavity 400 is filled with a solid-liquid phase change material 500, and the solid-liquid phase change material 500 covers the outer periphery of the corresponding air intake pipe 300.

[0041] Specifically, such as Figure 1 and Figure 3 As shown, multiple intake pipes 300 are fixedly installed side-by-side at intervals inside the connecting bracket 200. The interior of the multiple intake pipes 300 is used for engine air intake. Their specific number and area need to be designed according to the intake resistance of the matching engine. Furthermore, the multiple intake pipes 300 converge at their starting points to a point such as... Figure 1 The common air inlet 110 shown is the intercooler air inlet, which converges at the end into a common air outlet 120, the intercooler air outlet. The connecting bracket 200 is made of a thermally conductive material and is tightly connected to the outer wall of the intake pipe 300 (it can be fixed by welding). It not only serves to fix the intake pipe 300 but also conducts heat, allowing some of the intake heat from the intake pipe 300 to be transferred to the periphery of the connecting bracket 200. To improve heat conduction efficiency, in one specific embodiment, the connecting bracket 200 is made of a material with high thermal conductivity (such as copper or aluminum).

[0042] Furthermore, the outer periphery of the intake pipe 300 is covered with a solid-liquid phase change material 500. The phase change temperature of the material is selected to be consistent with the ideal intake air temperature of the matched engine, generally around 30-45℃. The selection of the phase change material filling amount is based on the design of the maximum single temperature impact of the matched engine, with the principle of maintaining a stable outlet air temperature. In this way, when high-temperature gas impacts the inside of the intake pipe 300 for a short time, the material absorbs latent heat through phase change to cool the intake air heat, preventing temperature shocks and ensuring the engine's intake air volume requirements and normal combustion. In addition, some or all of the multiple intake pipes 300 and the connecting bracket 200 together define a cavity 400, each cavity 400 is filled with solid-liquid phase change material 500, which remains around the intake pipe 300 even after melting, ensuring heat exchange efficiency.

[0043] It should be noted that in this embodiment, the external shape and size of the intercooler are similar to those of a traditional water-cooled intercooler, and the coolant radiator, circulation pump, water pipes and other parts of the original water-cooled intercooler can be used, which facilitates the replacement and upgrading of the original water-cooled intercooler. Compared with the traditional intercooler, it can cool the intake air temperature to below the ambient temperature, and can also keep the engine intake air temperature within the ideal operating range in high-temperature environments.

[0044] In one embodiment of this utility model, such as Figure 2 As shown, the connecting bracket 200 is in the shape of a grid and includes a plurality of connecting grids 210 connected in sequence. Each connecting grid 210 has a corresponding air intake pipe 300 inside, and the air intake pipe 300 is fixedly connected to the connecting grid 210 to achieve heat transfer.

[0045] Specifically, the outer wall of each intake pipe 300 and the corresponding connecting mesh 210 together define a cavity 400. Solid-liquid phase change material 500 is filled in the cavity 400 so that the outer periphery of each intake pipe 300 is covered with solid-liquid phase change material 500. When each intake pipe 300 is impacted by high-temperature gas inside for a short time, it can absorb latent heat through material phase change to cool the intake heat. After the phase change material melts, it can also remain around the intake pipe 300 to ensure heat exchange efficiency.

[0046] In one embodiment of this utility model, such as Figure 2 As shown, the connecting grid 210 includes a ring-shaped frame 211 and a skeleton disposed inside the frame 211. The outer edge of the skeleton is fixedly connected to the inner surface of the frame 211, and the inner edge of the skeleton is fixedly connected to the corresponding air intake pipe 300 to achieve heat transfer.

[0047] It should be noted that in this embodiment, the frame 211 is annular, and the annulus can be rectangular, circular, elliptical, or irregularly shaped; this embodiment does not impose specific limitations on this. Furthermore, the frames 211 of two adjacent connecting grids 210 can be independent and fixedly connected to each other, or they can share a portion of each other. The specific shape of the skeleton is not specifically limited, as long as it can be used to fix the outer wall of the intake pipe 300 and the frame 211. The fixing connection method includes, but is not limited to, integral molding and welding. The cavity 400 is formed by the outer wall of the intake pipe 300, the corresponding frame 211, and the skeleton.

[0048] In one embodiment of this utility model, such as Figure 2 As shown, the frame includes a plurality of connecting plates 212 spaced apart along the outer periphery of the corresponding air intake pipe 300. One end of each connecting plate 212 is fixedly connected to the frame 211, and the other end is fixedly connected to the outer wall of the corresponding air intake pipe 300.

[0049] It should be noted that the number of connecting plates 212 can be set according to requirements, for example, two, three, four, or more. Furthermore, the connecting plates 212 can be evenly and spaced around the corresponding air intake pipe 300, or they can be unevenly and spaced around the corresponding air intake pipe 300; this embodiment does not impose a specific limitation on this. The cavity 400 is defined by the outer wall of the air intake pipe 300, the corresponding frame 211, and the multiple connecting plates 212, so that the phase change material remains around each air intake pipe 300 before and after melting. Furthermore, a portion of the heat from the air intake pipe 300 is transferred to the corresponding frame 211 through the multiple connecting plates 212, and then to the periphery of the entire connecting bracket 200 to achieve heat transfer.

[0050] In one embodiment of this utility model, such as Figure 2 As shown, multiple connecting grids 210 are arranged in an array, and multiple air intake pipes 300 are arranged in an array to ensure the uniformity of heat exchange efficiency of each air intake pipe 300.

[0051] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, a coolant channel 600 is formed between the housing 100 and the connecting bracket 200 for the flow of coolant 700.

[0052] Specifically, the connecting bracket 200 exchanges heat with the coolant 700 flowing through the coolant passage 600. The coolant 700 can carry away the intake heat transferred to the periphery of the connecting bracket 200, thereby maintaining the intake temperature of the engine.

[0053] It should be noted that, as Figure 1 As shown, the intercooler also includes a coolant inlet 130 and a coolant outlet 140, and their specific arrangement can be as follows: Figure 1 As shown, coolant 700 flows into the intercooler through coolant inlet 130, then flows through the intercooler's coolant passage 600 and exits through coolant outlet 140. The coolant 700 exiting coolant outlet 140 can be circulated by a pump to the vehicle's front radiator for cooling.

[0054] In one embodiment of this utility model, such as Figure 2 As shown, one or more sets of heat exchange fins 800 are provided in the coolant channel 600, and one or more sets of heat exchange fins 800 are fixed to the outer periphery of the connecting bracket 200; each set of heat exchange fins 800 includes one heat exchange fin 800 or multiple heat exchange fins 800 arranged in sequence at intervals.

[0055] It should be noted that, in this embodiment, there is no specific limitation on the number of groups of heat exchange fins 800 provided in the coolant channel 600. There can be one group, two groups, or more groups. The more groups, the higher the heat exchange efficiency through the heat exchange fins 800, but the corresponding structure is also more complex. If multiple groups of heat exchange fins 800 are provided in the coolant channel 600, the number of heat exchange fins 800 in each group can be the same or different. Specifically, there can be one group or multiple groups spaced apart. There is also no specific limitation on the number of heat exchange fins 800 in each group; those skilled in the art can configure it according to actual needs.

[0056] Specifically, one or more sets of heat exchange fins 800 are fixed to the outer periphery of the connecting bracket 200. The intake heat from the periphery of the connecting bracket 200 can be transferred to the heat exchange fins 800, and further exchanged with the coolant 700 in the coolant channel 600 through the heat exchange fins 800, carrying away the heat transferred to the heat exchange fins 800 and maintaining the intake temperature.

[0057] In one embodiment of this utility model, such as Figure 2 As shown, one or more cooling plates 900 are fixedly disposed on the outer periphery of the connecting bracket 200, and one or more sets of heat exchange fins 800 are located on the outer periphery of one or more cooling plates 900 and fixed to the outer periphery of the connecting bracket 200 by the corresponding cooling plate 900. The cooling plate 900 is a semiconductor cooling plate.

[0058] It should be noted that in this embodiment, the cooling plate 900 is a semiconductor cooling plate. After being powered on, its cooling temperature is not limited by the ambient temperature, and it can achieve a cooling effect lower than that of traditional air-cooled or water-cooled intercoolers. Furthermore, there can be one or multiple cooling plates 900 fixed to the outer periphery of the connecting bracket 200, which can be designed according to the most severe heat exchange scenario of the engine. That is, through the combined cooling effect of the semiconductor cooling plate and the coolant 700, the engine intake air temperature requirements can be met under the most severe scenario. In addition, a set of heat exchange fins 800 can be fixedly connected to the outer periphery of one cooling plate 900, or multiple sets of heat exchange fins 800 can be fixedly connected. If multiple cooling plates 900 are fixedly connected to the outer periphery of the connecting bracket 200, the number of sets of heat exchange fins 800 on the outer periphery of each cooling plate 900 can be the same or different. In one specific embodiment, such as... Figure 2 As shown, four cooling plates 900 are fixedly and spaced apart on the outer periphery of the connecting bracket 200. Four sets of heat exchange fins 800 are fixedly and spaced apart on the outer periphery of the four cooling plates 900, and one cooling plate 900 is connected to one set of heat exchange fins 800.

[0059] Specifically, the cooling plate 900 is fixedly installed on the outer periphery of the connecting bracket 200, and the heat exchange fins 800 are located on the outer periphery of the cooling plate 900. The intake heat from the outer periphery of the connecting bracket 200 can be transferred to the cooling plate 900. The cooling plate 900 is a semiconductor cooling plate, which can absorb some heat after being powered on. Another part of the heat from the cooling plate 900 can be further transferred to the heat exchange fins 800. The heat exchange fins 800 exchange heat with the coolant 700 flowing through the coolant channel 600. The heat transferred to the heat exchange fins 800 is carried away by the flowing coolant 700. That is, the cooling plate 900 and the coolant 700 work together to maintain the intake temperature under the worst scenario.

[0060] It should be noted that when the ambient temperature is low and the cooling capacity is sufficient, the semiconductor cooling plate may not need to be powered on. In this case, the semiconductor cooling plate does not have a heat absorption function, but only a heat conduction function. That is, the heat from the air intake around the connecting bracket 200 is transferred to the cooling plate 900, and the heat from the cooling plate 900 is transferred to the heat exchange fins 800. The heat exchange fins 800 exchange heat with the coolant 700 flowing through the coolant channel 600. The heat transferred to the heat exchange fins 800 is carried away by the flowing coolant 700. That is, only the coolant 700 is used for heat dissipation, reducing energy consumption.

[0061] In one embodiment of this utility model, such as Figure 2 As shown, the two ends of each heat exchange fin 800 in one or more sets of heat exchange fins 800 are fixed to the corresponding cooling plate 900 and the shell 100 respectively. The connecting bracket 200 is fixedly connected to the inside of the shell 100 through one or more cooling plates 900 and one or more sets of heat exchange fins 800.

[0062] Specifically, the two ends of the heat exchange fins 800 are fixed to the corresponding cooling plate 900 and the shell 100, respectively, which can increase the heat exchange area between the heat exchange fins 800 and the coolant 700 flowing through the coolant channel 600 and improve the heat exchange efficiency.

[0063] The intercooler provided by this utility model includes a hollow shell 100, a connecting bracket 200 fixedly connected to the inside of the shell 100, and multiple intake pipes 300. A solid-liquid phase change material 500 is coated around the outer periphery of the corresponding intake pipe 300. During short-term impact from high-temperature internal gas, the material absorbs latent heat through phase change to cool the intake air. This maintains stable engine intake air temperature even with rapid changes in engine load and a rapid increase in turbocharger outlet temperature, preventing temperature shocks and ensuring the engine's intake air volume requirements and normal combustion. Furthermore, the multiple intake pipes 300 are fixedly arranged side-by-side at intervals inside the connecting bracket 200, and some or all of the intake pipes 300 are connected to the connecting bracket 200 to achieve heat transfer. The connecting bracket 200 not only fixes the intake pipes 300 but also acts as a heat-conducting support. Some of the intake heat from the intake pipes 300 can be transferred to the periphery of the connecting bracket 200 to reduce the intake air temperature. Furthermore, some or all of the multiple intake pipes 300 together with the connecting bracket 200 define a cavity 400, that is, the cavity 400 is formed around the intake pipe 300, and each cavity 400 is filled with a solid-liquid phase change material 500. Even after the solid-liquid phase change material 500 melts, it can remain around the intake pipe 300 to ensure heat exchange efficiency.

[0065] This utility model also provides an automobile, including the intercooler in Embodiment 1.

[0066] Using the above technical solution, when the intake pipe of the automotive intercooler is impacted by high-temperature gas inside for a short time, the latent heat can be absorbed by the solid-liquid phase change material covering the outer periphery of the intake pipe to cool the intake air. Some of the intake air heat from the intake pipe can be transferred to the periphery of the connecting bracket through the connecting bracket to maintain the intake air temperature, prevent temperature shock, and ensure the engine intake air volume requirement and normal combustion.
