[0096] Unless otherwise stated, the numerical ranges herein include not only the entire range within its two endpoints but also include several sub-ranges contained therein.

[0097] Reference Figure 1 The utility model provides a sealing member. The sealing member includes an inner sealing portion 310 and an outer sealing portion 320. An inner sealing channel (i.e., a third airflow channel 311) is defined in the inner sealing portion 310. The outer sealing portion 320 is disposed at the periphery of the inner sealing portion 310, and the outer sealing portion 320 is at least partially connected to the inner sealing portion 310, and an outer sealing channel (i.e., a third cooling channel) is defined between the outer sealing portion 320 and the inner sealing portion 310. The inner sealing portion 310 and the outer sealing portion 30 are used to be connected to an external structure so that the third airflow channel 311 is separated from the third cooling channel. By providing the inner sealing portion 310 and the outer sealing portion 320, the sealing member can be better connected to the external structure, ensuring effective isolation between the airflow channel and the cooling channel, thereby improving the reliability and performance of the equipment.

[0098] On the basis of the above-mentioned embodiment, a first spacer 330 is provided between the inner sealing part 310 and the outer sealing part 320, and the first spacer 330 separates the third cooling channel into a third cooling channel A 321A and a third cooling channel B 321B.

[0099] Optionally, the third airflow channel 311 is connected along the thickness direction DW of the seal. The third cooling channel is connected along the thickness direction DW of the seal. Therefore, the third airflow channel 311 and the third cooling channel can be connected to the external channel at intervals through the sealed connection between the inner sealing part 310 and the outer sealing part 320 and the external structure.

[0100] Reference Figure 2-Figure 9 The utility model provides a cylinder head assembly, including a cylinder head 100, a supercharger turbine 200 and a seal 300. The cylinder head 100 is provided with a cylinder head channel. The supercharger turbine 200 is provided with a turbine channel. The seal 300 is arranged between the cylinder head 100 and the supercharger turbine 200, and is respectively sealed and connected to the cylinder head 100 and the supercharger turbine 200 to connect the cylinder head channel and the turbine channel. In the utility model, the cylinder head 100 and the supercharger turbine 200 are separately arranged, which can facilitate the independent maintenance and repair of the engine and the supercharger turbine 200, and provide greater flexibility for the engine layout. By setting the seal 300, a reliable connection point is established between the cylinder head 100 and the supercharger turbine 200, ensuring the connection seal between the cylinder head 100 and the supercharger turbine 200, preventing gas and liquid leakage, maintaining good sealing of the system, and ensuring the normal operation of the engine and the supercharger turbine 200.

[0101] In some embodiments of the utility model, the cylinder head channel includes a first airflow channel 101 and a first cooling channel 102 separated from each other. The turbine channel includes a second airflow channel 201 and a second cooling channel 202 separated from each other. The first airflow channel 101, the second airflow channel 201 and the third airflow channel 311 are connected to form an airflow channel, the first cooling channel 102, the second cooling channel 202 and the third cooling channel are connected to form a cooling channel, and the airflow channel and the cooling channel are separated by a seal 300. The cylinder head 100 and the supercharger turbine 200 are directly connected through the airflow channel, which can relatively shorten the exhaust path from the combustion chamber exhaust to the turbocharger. Such a design can reduce resistance and pressure drop, improve exhaust efficiency, and promote faster exhaust gas extraction and turbine response speed. In some specific embodiments, the traditional exhaust manifold setting can be omitted, so that the exhaust pipeline is more simplified, the components and interfaces are reduced, the complexity of the engine system is reduced, and the possible leakage points in the system are reduced. By optimizing the exhaust piping and shortening the exhaust path, the inertial load on the turbocharger can be reduced, improving its speed response speed, helping to reduce turbo lag and provide a more direct and immediate power response.

[0102] In some embodiments of the utility model, the airflow channel is streamlined, and the cooling channel is adapted to the shape of the airflow channel. Through the streamlined setting, the fluid resistance in the channel is reduced, the energy loss is reduced, and the engine efficiency is improved.

[0103] In some embodiments of the present invention, the cylinder head 100 includes a cylinder head body 110 and a first cooling sleeve 120. A first airflow channel 101 is formed in the cylinder head body 110. The first cooling sleeve 120 is circumferentially arranged around the main body of the cylinder head 100 to form a first cooling channel 102 between the first cooling sleeve 120 and the main body of the cylinder head 100. It can be understood that the first cooling channel 102 is arranged around the first airflow channel 101, and by forming a uniformly flowing coolant around the periphery of the first airflow channel 101, a more balanced temperature distribution can be provided, thereby avoiding the problem of local overheating or insufficient cooling, and protecting engine components from temperature stress and loss.

[0104] Optionally, the cylinder head body 110 and the first cooling jacket 120 are integrally formed. Integral forming can reduce the seams and joints between the cylinder head body 110 and the first cooling jacket 120, thereby reducing the risk of gas and liquid leakage or mixing and improving the sealing performance. In addition, integral forming can also reduce the overall weight of the cylinder head 100, simplify the manufacturing process, reduce production costs, and improve the overall quality and stability of the product.

[0105] The supercharger turbine 200 includes a supercharger turbine body 210 and a second cooling sleeve 220. A second airflow channel 201 is formed in the supercharger turbine body 210. The second cooling sleeve 220 is arranged circumferentially around the supercharger turbine body 210 to form a second cooling channel 202 between the second cooling sleeve 220 and the supercharger turbine body 210. It can be understood that the second cooling channel 202 is arranged around the second airflow channel 201, and by forming a uniformly flowing coolant around the second airflow channel 201, a more balanced temperature distribution can be provided, local overheating or insufficient cooling problems can be avoided, and turbine components can be protected from temperature stress and loss. Adding a cooling water jacket to the outer surface of the supercharger turbine 200 enhances the overall strength of the volute, especially for the upturned turbocharger, reducing the risk of cracking during use. At the same time, the exhaust temperature in the volute is reduced, and a lower grade volute material can be used, reducing the application cost of the volute. The small circulation water channel of the cylinder head 100 is connected to the volute water channel, which makes better use of the exhaust heat and improves the warm-up speed of the engine.

[0106] Optionally, the supercharger turbine body 210 and the second cooling sleeve 220 are integrally formed. Integral forming can reduce the seams and joints between the supercharger turbine body 210 and the second cooling sleeve 220, thereby reducing the risk of gas and liquid leakage or mixing and improving the sealing performance. In addition, integral forming can also reduce the overall weight of the supercharger turbine 200, simplify the manufacturing process, reduce production costs, and improve the overall quality and stability of the product.

[0107] On the basis of the above embodiment, the inner seal 310 is sealed and connected with the cylinder head body 110 and the supercharger turbine body 210 respectively. The outer seal 320 is arranged at the periphery of the inner seal 310, and the outer seal 320 is spaced apart from the inner seal 310, and the outer seal 320 is sealed and connected with the first cooling pipe jacket 120 and the second cooling pipe jacket 220 respectively. Through the sealed connection of the inner seal 310 with the cylinder head body 110 and the supercharger turbine body 210, and the sealed connection of the outer seal 320 with the first cooling pipe jacket 120 and the second cooling pipe jacket 220, an effective sealing effect can be achieved. It helps to prevent gas and liquid leakage, ensure the normal operation of the system and improve the reliability of the system. By installing the outer seal 320 outside the inner seal 310 and connecting it with the corresponding components, the structural stability between the components can be enhanced. It helps to improve the reliability and durability of the overall assembly and reduce the risk of loosening or failure caused by vibration and thermal expansion.

[0108] In some further embodiments of the present invention, the first cooling jacket 120 includes an upper water jacket 121 and a lower water jacket 122. A first water inlet channel 1021 is defined in the upper water jacket 121, and a first water outlet channel 1022 is defined in the lower water jacket 122.

At the same time, after the coolant is fully heat-exchanged in the lower water jacket 122 and the water inlet jacket 221, it flows to the water outlet jacket 222 and the upper water jacket 121, and the coolant refluxes through the pressure difference between the upper water jacket 121 and the lower water jacket 122 of the cylinder head 100. The coolant circulates by using the pressure difference between the upper water jacket 121 and the lower water jacket 122, and no additional pressure source input is required. In addition, the connecting channel is integrated in the volute and the cylinder head 100, and no additional connecting pipeline is required, which is convenient for layout and saves layout space.

[0111] On the basis of the above embodiment, the upper water jacket 121 is located above the lower water jacket 122.
