[0002] The existing intercooler structure is not highly integrated. It simply integrates the inlet and outlet water and air chambers. It still requires a large number of external pipes to carry water and air. The pipes are cumbersome, complicated, not compact, have many leak points, and have many problems with water and air leakage at the joint surfaces. Utility Model Content

[0003] The main objective of this invention is to provide an intercooler that addresses the problem of low integration of piping in existing intercoolers.

[0004] To achieve the above objectives, this utility model provides an intercooler, including a first end cap and a second end cap, which are disposed opposite to and connected to each other; wherein, the first end cap includes a first cover body and a first water passage disposed on the first cover body, the first water passage being used to supply a first liquid; the second end cap includes a second cover body and a second water passage and a gas passage disposed on the second cover body, the second water passage being used to supply a second liquid, and the gas passage being used to supply gas, so as to cool the second liquid and the gas through the first liquid.

[0005] Furthermore, the first inlet and the first outlet of the first waterway are located at the same end along the length of the first end cap and are spaced apart along the width of the first end cap.

[0006] Furthermore, both the first inlet and the first outlet are located at the second end of the length direction of the first end cap, and the first inlet is located at the first end of the width direction of the first end cap, while the first outlet is located at the second end of the width direction of the first end cap.

[0007] Furthermore, the first water path includes a first section, a second section, and a third section connected sequentially along the flow direction of the first liquid. The first section and the second section both extend along the length direction of the first end cap and are arranged sequentially along the width direction of the first end cap. The third section extends along the width direction of the first end cap. The first section and the second section are both located at the first end of the third section near the width direction of the first end cap.

[0008] Furthermore, the second inlet and the second outlet of the second waterway are located at opposite ends of the length of the second end cap.

[0009] Furthermore, the second inlet is located at the second end of the second end cap along its length, and the second outlet is located at the first end of the second end cap along its length.

[0010] Furthermore, the second water path includes a fourth section, a fifth section, and a sixth section connected sequentially along the flow direction of the second liquid. The fourth and sixth sections extend along the width direction of the second end cap and are spaced apart along the length direction of the second end cap. The fifth section extends along the length direction of the second end cap, and the ratio between the width of the fifth section and the width of the second end cap is greater than or equal to 0.3.

[0011] Furthermore, the air passage inlet is located at the first end in the length direction of the second end cover, and the air passage outlet is located at the first end in the width direction of the second end cover.

[0014] This invention provides an intercooler comprising a first end cover and a second end cover, which are disposed opposite to and connected to each other. The first end cover includes a first cover body and a first water passage on the first cover body, through which a first liquid flows. The second end cover includes a second cover body and a second water passage and a gas passage on the second cover body, through which a second liquid flows and a gas passage flows, thereby cooling the second liquid and gas through the first liquid. Furthermore, this invention proposes an integrated intercooler, specifically where the first end cover includes a first cover body and a first water passage on the first cover body, and the second end cover includes a second cover body and a second water passage and a gas passage on the second cover body. By directly integrating the water passage and gas passage in the end cover, the first liquid can cool the second liquid and gas through the first water passage, effectively eliminating the layout complexity and lack of compactness caused by numerous external pipes in traditional intercoolers.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 5As shown, this utility model provides an intercooler, including a first end cap 1 and a second end cap 2, which are disposed opposite to and connected to each other. The first end cap 1 includes a first cover body 11 and a first water passage 3 disposed on the first cover body 11, the first water passage 3 being used to supply a first liquid. The second end cap 2 includes a second cover body 21 and a second water passage 4 and a gas passage 5 disposed on the second cover body 21, the second water passage 4 being used to supply a second liquid, and the gas passage 5 being used to supply gas, so as to cool the second liquid and gas through the first liquid. Applying the technical solution of this utility model, an integrated intercooler is proposed. Specifically, the first end cap 1 includes a first cover body 11 and a first water passage 3 disposed on the first cover body 11, while the second end cap 2 includes a second cover body 21 and a second water passage 4 and a gas passage 5 disposed on the second cover body 21. By directly integrating the first water passage 3, the second water passage 4, and the gas passage 5 into the two end caps of the intercooler, the first liquid can cool the second liquid and gas. This solves the problem of low integration of pipelines in existing intercoolers, effectively eliminating the layout complexity and insufficient compactness caused by numerous external pipelines in existing intercoolers. It reduces the number of parts, thereby reducing the potential risk of leakage, improving overall reliability and maintenance convenience. This makes the intercooler not only more compact and simple, but also improves its cooling efficiency and durability, bringing significant technological progress to the engine system.

[0025] like Figure 1 As shown, the first inlet 31 and the first outlet 32 ​​of the first water passage 3 are located at the same end along the length of the first end cover 1 and are spaced apart along the width of the first end cover 1. In this invention, the first inlet 31 and the first outlet 32 ​​of the first water passage 3 are located at the same end along the length of the first end cover 1 and are spaced apart along the width of the first end cover 1. This layout optimizes the flow path of the first liquid, achieving efficient circulation of the cooling fluid inside the intercooler. This not only improves cooling efficiency but also reduces hydraulic losses, making the intercooler operation more economical. Furthermore, designing the first inlet 31 and the first outlet 32 ​​at the same end simplifies the connection of external pipes, reduces the risk of leakage due to excessive piping, and makes the overall structure of the intercooler more compact, saving installation space and enhancing the reliability and ease of maintenance of the intercooler.

[0026] like Figure 1As shown, both the first inlet 31 and the first outlet 32 ​​are located at the second end of the length direction of the first end cover 1, and the first inlet 31 is located at the first end of the width direction of the first end cover 1, while the first outlet 32 ​​is located at the second end of the width direction of the first end cover 1. In this invention, both the first inlet 31 and the first outlet 32 ​​are positioned at the ends of the length direction of the first end cover 1, and the clever arrangement places the first inlet 31 at one end of the width direction of the first end cover 1, while the first outlet 32 ​​is located at the opposite end. This design not only optimizes the flow path of the first liquid, ensuring that the first liquid can circulate fully inside the intercooler and improving cooling efficiency, but also effectively avoids direct short-circuiting of the first liquid by setting the first inlet 31 and the first outlet 32 ​​at different positions on the first end cover 1, enhancing the uniform distribution of the first liquid and further improving the cooling performance and overall heat exchange efficiency of the intercooler. At the same time, this layout reduces the number of pipe connection points, lowers the potential leakage risk, and improves the reliability and maintenance convenience of the intercooler.

[0027] Of course, in addition to the layout described in this utility model, the specific positions and shapes of the first inlet 31 and the first outlet 32 ​​can be adjusted to adapt to different cooling requirements and space constraints, achieving a more flexible integrated design. In other embodiments not shown in the figures, the positions and shapes of the first inlet 31 and the first outlet 32 ​​can be fine-tuned according to actual operating conditions to achieve optimal cooling effect and system compatibility. In this way, not only can the external piping layout of the intercooler be simplified, but a more compact and efficient water circuit layout can also be achieved in a limited space, thereby significantly improving the overall performance of the engine cooling system.

[0028] like Figure 3 As shown, the first water channel 3 includes a first segment 33, a second segment 34, and a third segment 35 connected sequentially along the flow direction of the first liquid. The first segment 33 and the second segment 34 extend along the length direction of the first end cap 1 and are sequentially arranged along the width direction of the first end cap 1. The third segment 35 extends along the width direction of the first end cap 1. The first segment 33 and the second segment 34 are both located at the first end of the third segment 35 closest to the width direction of the first end cap 1. In this invention, the structure of the first water channel 3 is cleverly planned, including the first segment 33, the second segment 34, and the third segment 35 connected sequentially along the flow direction of the first liquid. This ensures smoother and more uniform flow of cooling water inside the intercooler, thereby improving cooling efficiency. By segmenting the water channel and arranging it along a specific direction, not only is the water flow path optimized and the resistance during water flow reduced, but the entire intercooler structure is also made more compact, significantly improving space utilization. Furthermore, this layout reduces the connections between components, lowers the potential risk of leakage, and improves the reliability of the intercooler.

[0029] In other embodiments not shown, each section of the first waterway 3 can be adjusted according to actual needs, such as changing its extension direction or position, to adapt to different engine designs and operating environments, thereby further optimizing cooling performance and installation convenience.

[0030] like Figure 2 As shown, the second inlet 41 and the second outlet 42 of the second water passage 4 are located at opposite ends of the length direction of the second end cap 2. In this invention, the second inlet 41 and the second outlet 42 of the second water passage 4 are located at opposite ends of the length direction of the second end cap 2. This arrangement maximizes the flow path of the second liquid inside the intercooler, thereby enhancing the cooling effect on the second liquid. The second liquid enters from the second inlet 41, flows through the entire intercooler, fully exchanges heat with the first liquid, and finally flows out from the second outlet 42. This design not only improves the cooling efficiency of the water passage but also reduces unnecessary bends in the water passage, lowers flow resistance, and makes the intercooler operate more smoothly. At the same time, by optimizing the flow direction of the second liquid, direct collision of the second liquid inside the end cap is avoided, reducing energy loss and further improving the overall performance of the intercooler. In addition, the separate arrangement of the second inlet 41 and the second outlet 42 also facilitates connection with external cooling systems and simplifies the installation process.

[0031] like Figure 2 As shown, the second inlet 41 is located at the second end of the length direction of the second end cover 2, and the second outlet 42 is located at the first end of the length direction of the second end cover 2. In this invention, the second inlet 41 is located at the second end of the length direction of the second end cover 2, while the second outlet 42 is located at the first end of the length direction of the second end cover 2. This layout optimizes the circulation path of the second liquid, ensuring that the second liquid in the second water channel 4 can fully flow through the entire intercooler, improving the heat exchange efficiency with the first liquid. When the cooling water enters from the second inlet 41, it flows along the designed water channel to the other end of the entire intercooler, and then exits through the second outlet 42. This process not only achieves effective cooling of the second liquid, but also avoids the occurrence of local overheating, enhancing the overall performance and reliability of the intercooler. By setting the second inlet 41 and the second outlet 42 at different positions at both ends, it also promotes the uniform distribution of water flow, making the internal temperature of the intercooler more balanced, further improving the cooling effect and the working stability of the engine.

[0032] Of course, in other embodiments not shown in the figure, the positions of the second inlet 41 and the second outlet 42 can be adjusted according to specific application requirements, but the principle of opposite ends is always maintained to achieve the best cooling water circulation effect. This integrated design reduces reliance on external piping, simplifies the assembly process, reduces potential leakage risks, and makes a significant contribution to improving the reliability and maintenance convenience of the entire vehicle.

[0033] like Figure 4 As shown, the second water path 4 includes a fourth segment 43, a fifth segment 44, and a sixth segment 45 connected sequentially along the flow direction of the second liquid. The fourth segment 43 and the sixth segment 45 both extend along the width direction of the second end cap 2 and are spaced apart along the length direction of the second end cap 2. The fifth segment 44 extends along the length direction of the second end cap 2, and the ratio between the width of the fifth segment 44 and the width of the second end cap 2 is greater than or equal to 0.3. In this invention, the second water path 4, including the fourth segment 43, the fifth segment 44, and the sixth segment 45 connected sequentially along the cooling water flow direction, ensures a more direct path for the second liquid when entering and leaving, reducing the detours of the second water path 4, thereby reducing flow resistance and increasing the water flow rate. More importantly, the fifth segment 44 extends along the length of the second end cover 2, and the ratio between its width and the width of the second end cover 2 is greater than or equal to 0.3. This means that the fifth segment 44 almost occupies the entire width of the second end cover 2. This design maximizes the contact area between the cooling water and the second end cover 2, improves heat exchange efficiency, and ensures that the cooling water can release heat more fully when passing through the intercooler, thereby achieving better heat dissipation and improving the cooling performance of the intercooler. At the same time, it reduces the complexity of the water circuit design, simplifies the overall structure, reduces manufacturing costs, and improves the reliability and service life of the intercooler.

[0034] like Figure 2 As shown, the gas inlet 51 of the gas passage 5 is located at the first end of the length direction of the second end cover 2, and the gas outlet 52 of the gas passage 5 is located at the first end of the width direction of the second end cover 2. In this utility model, the gas inlet 51 of the gas passage 5 is located at the first end of the length direction of the second end cover 2, and the gas outlet 52 of the gas passage 5 is located at the first end of the width direction of the second end cover 2. This layout optimizes the flow path of gas inside the intercooler, allowing high-temperature air to travel along the optimal path from the gas inlet 51 to the gas outlet 52, thereby increasing the heat exchange efficiency between the air and the first liquid and ensuring that the gas is effectively cooled after passing through the intercooler. In addition, this design also utilizes the advantages of spatial layout to achieve efficient isolation and compact arrangement between the gas passage 5 and the second water passage 4, reducing the risk of leakage caused by the complexity of the intercooler's piping, and enhancing the reliability and maintenance convenience of the intercooler. By setting the gas inlet 51 and the gas outlet 52 at the ends in different directions, not only is the three-dimensional space of the intercooler effectively utilized, but the overall assembly process is also simplified, reducing potential failure points caused by improper interface positions.

[0035] like Figure 2As shown, the air passage 5 includes multiple air passage outlets 52, which are spaced apart along the length of the second end cover 2. In this invention, the intercooler design integrating multiple air passage outlets 52 makes the cooling process of high-temperature gas more efficient and uniform. The spaced arrangement of multiple air passage outlets 52 along the length of the second end cover 2 ensures a more complex flow path for the gas inside the intercooler, thereby increasing the contact time between the gas and the cooling water and improving cooling efficiency. Simultaneously, the spaced air passage outlets 52 disperse the airflow, preventing excessively fast local airflow, reducing airflow disturbance to the cooling water, maintaining a stable flow of the cooling water, and further enhancing the cooling effect. Furthermore, this design also helps reduce the overall gas resistance of the intercooler, improving the engine's intake efficiency, thereby improving engine performance without increasing additional energy consumption.

[0036] Although this utility model describes a plurality of air outlets 52 spaced apart along the length of the second end cover 2, in other embodiments, the number and layout of the air outlets 52 can be adjusted according to specific application scenarios and cooling requirements, such as being arranged along the width of the second end cover 2 or using a staggered layout, in order to achieve the best cooling effect.

[0037] like Figure 5 As shown, the gas path 5 includes a seventh segment 53 and an eighth segment 54 connected sequentially along the gas flow direction. The seventh segment 53 is located at the first end of the second end cover 2 along its length, and the eighth segment 54 extends along the length of the second end cover 2, with the ratio of its width to the width of the second end cover 2 being greater than or equal to 0.9. In this invention, the integrated design of the gas path 5 optimizes the gas flow path. Specifically, the seventh segment 53, located at the first end of the second end cover 2 along its length, serves as the airflow inlet segment, ensuring that the gas can smoothly enter the intercooler. Subsequently, the gas flows along the eighth segment 54, which extends along the length of the second end cover 2, with its width to the width of the second end cover 2 being greater than or equal to 0.9. This feature ensures that after the cooling process, the gas can flow out from the width direction of the second end cover 2 with a nearly uniform speed and pressure distribution, thereby improving the uniformity of the airflow and the cooling efficiency. By matching the width of the gas passage 5 with the size of the end cap, not only are eddies and resistance during gas flow reduced, but also the heat exchange between the first liquid and gas is ensured to be more complete, ultimately improving the overall performance of the intercooler.

[0038] In other embodiments not shown, the design of the air passage 5 can be further adjusted to accommodate different cooling requirements and space constraints, thereby improving the applicability and reliability of the intercooler.

[0039] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0040] This utility model provides an intercooler, including a first end cap 1 and a second end cap 2, which are disposed opposite to and connected to each other. The first end cap 1 includes a first cover body 11 and a first water passage 3 disposed on the first cover body 11, the first water passage 3 being used to supply a first liquid. The second end cap 2 includes a second cover body 21 and a second water passage 4 and a gas passage 5 disposed on the second cover body 21, the second water passage 4 being used to supply a second liquid, and the gas passage 5 being used to supply gas, so as to cool the second liquid and gas through the first liquid. Applying the technical solution of this utility model, an integrated intercooler is proposed. Specifically, the first end cap 1 includes a first cover body 11 and a first water passage 3 disposed on the first cover body 11, while the second end cap 2 includes a second cover body 21 and a second water passage 4 and a gas passage disposed on the second cover body 21. By directly integrating water and gas passages into the end cap, the first liquid can cool the second liquid and gas through the first water passage 3, effectively eliminating the layout complexity and lack of compactness caused by numerous external pipes in traditional intercoolers. Furthermore, the integrated design reduces the number of connections between parts, thereby lowering the potential risk of leakage and improving overall reliability and ease of maintenance. This technical solution makes the intercooler not only more compact and simple but also improves its cooling efficiency and durability, bringing significant technological advancements to engine systems.
