Technical Field
[0001] This utility model relates to the field of automotive turbocharging, specifically to a novel spoiler for a water-cooled intercooler. Background Technology
[0002] With the continuous advancement of internal combustion engine technology, turbocharging has played a crucial role in improving engine power and fuel efficiency. The intercooler, as a key component of the turbocharging system, is used to reduce intake air temperature, thereby improving engine efficiency and reliability. Water-cooled intercoolers absorb heat from compressed air through coolant circulation, thus lowering the intake air temperature. However, traditional water-cooled intercoolers typically employ a simple straight-channel design, which easily leads to laminar flow as air passes through the intercooler, resulting in reduced heat exchange efficiency. Furthermore, uneven airflow distribution can cause localized overheating or insufficient cooling, affecting the overall performance of the intercooler. Therefore, to address these issues, a novel spoiler design is urgently needed that can effectively enhance airflow turbulence and improve heat exchange efficiency while maintaining low airflow resistance, and that is simple in structure, easy to manufacture, and easy to install. Summary of the Invention
[0003] The purpose of this invention is to provide a novel baffle plate for water-cooled intercoolers. By optimizing the shape and arrangement of the baffle plate, uniform airflow distribution and efficient heat exchange are achieved, while boiling is reduced, flow resistance is optimized, and the overall performance of the intercooler is improved. This design is applicable not only to existing water-cooled intercoolers...
[0004] The cooler can also be widely used in other cooling systems that require efficient heat exchange.
[0005] To achieve the above objectives, this utility model provides a novel baffle plate for a water-cooled intercooler, including a baffle plate base plate. The baffle plate base plate is a flat plate that matches the size of the water-cooled intercooler core and is assembled at the inlet of the water-cooled intercooler core in the liquid-side flow direction. The baffle plate base plate has baffles of different depths on its upper and lower sides in the direction parallel to the tube-plate assembly. The position of each baffle is above the liquid-side fins, so that the liquid can flow to the water-cooled intercooler core only through the baffles. Furthermore, there are two positioning protrusions on the baffle plate base plate for positioning with the upper guide shroud during assembly.
[0006] The baffle plate substrate needs to be welded together with the tube assembly, and the material is aluminum, which is beneficial for heat exchange.
[0007] The baffle plate base plate and the tube assembly have baffles of different depths on the upper and lower sides in the direction parallel to each other. The baffles are arranged asymmetrically on the baffle plate base plate of the intercooler. The depth of the baffles on one side decreases from left to right, while the depth of the baffles on the other side increases from left to right.
[0008] The spoiler substrate has two positioning protrusions, and at the corresponding position of the flow guide shroud that cooperates with the spoiler, there are also two stamped structures with recesses on the back and protrusions on the front. Their size is such that the two positioning protrusions on the spoiler substrate and the recesses on the flow guide shroud are embedded and overlap.
[0009] This utility model discloses a novel baffle plate for a water-cooled intercooler. Several baffles of varying sizes can reduce boiling, optimize flow resistance, and reduce the risk of subsequent durability failure within a limited space. It can effectively enhance the turbulence of the airflow and improve the heat exchange efficiency while ensuring low airflow resistance. Moreover, it has a simple structure and is easy to manufacture and install. Attached Figure Description

Detailed Implementation
[0017] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings and specific examples.
[0018] like Figure 1 The diagram shows a schematic of the baffle plate substrate of the novel baffle plate in the water-cooled intercooler of this utility model.
[0019] like Figure 2 The diagram shows the assembly structure of the new type of baffle plate in the water-cooled intercooler of this utility model.
[0020] like Figure 3 The diagram shown illustrates the optimized temperature performance of the novel baffle plate in the water-cooled intercooler of this invention.
[0021] like Figure 4 The diagram shown illustrates the optimized flow resistance performance of the novel baffle plate in the water-cooled intercooler of this invention.
[0022] The components included in the figure are: 1. spoiler base plate, 2. spoiler port, 3. positioning protrusion, 4.1. first main plate, 4.2. second main plate, 5.1. first baffle, 5.2. second baffle, 6. lower cover plate, 7. tube plate assembly, 8. water outlet pipe, 9. water inlet pipe, 10.1. first pressurization pipe, 10.2. second pressurization pipe, 11. flow guide.
[0023] The installation of the new type of baffle in the water-cooled intercooler is as follows:
[0024] The main body consists of a tube-and-fin assembly 7, which is a combination of heat dissipation tubes and fins. A first baffle 5.1 and a second baffle 5.2 are installed on the left and right sides of the outer surface of the tube-and-fin assembly 7. The upper and lower long edges of the baffles are relatively long, with rounded inward curves forming a bend. The inner curvature of the baffles fits against the outer wall of the tube-and-fin assembly 7. A central opening is provided for tooling positioning. Two grooves are opened on the left and right sides of the lower cover plate 6 to connect with the baffles.
[0025] The notch at the bend of the plate is fitted to the bottom of the core;
[0026] The first main plate 4.1 and the second main plate 4.2 are inserted into the core from the front and rear directions of the section of the tube assembly 7, respectively. The four outer edges of the main plate have an inward snap-fit groove structure. The whole is a rectangular plate with a uniformly sized, stamped, outward protruding hole in the middle. During assembly, the holes on the main plate correspond one-to-one with the tube assembly 7 to form a fastening and positioning. The spoiler base plate 1 is installed on the upper part of the core corresponding to the lower cover plate 6. The flow guide shroud 11 is installed on the flow guide plate. There is a local bulge on the flow guide shroud 11. The shape and direction of the bulge are consistent with the depth of the spoiler opening 2 on the spoiler plate 1. At the same time, four holes are opened on the bulge of the flow guide shroud 11, which respectively cooperate with the water inlet pipe 9, the water outlet pipe 8, the first pressurization pipe 10.1, and the second pressurization pipe 10.2. The pressurization pipe is a thin tube bent at 90° with abutments at both ends. The abutment at the head is used for snap-fitting, and the abutment at the tail is used for welding to the flow guide shroud.
[0027] Both the baffle plate substrate 1 and the tube assembly 7 are made of aluminum, which has good welding performance and is more conducive to heat exchange.
[0028] The flow plate substrate 1 and the tube assembly 7 have turbulence ports of varying depths on their upper and lower sides in a direction parallel to each other. These turbulence ports are arranged asymmetrically on the intercooler turbulence plate substrate, with their depths varying from... Figure 1As can be seen, the depth of the turbulence opening on one side decreases from left to right, while the depth of the turbulence opening on the other side increases from left to right.
[0029] The two positioning protrusions 3 on the spoiler substrate 1 have the same size as the two stamped structures with recesses on the back and protrusions on the front of the flow guide shroud 11 that cooperate with the spoiler. This allows the positioning protrusions 3 on the spoiler substrate 1 to be embedded and overlapped with the recesses on the flow guide shroud.
[0030] With the addition of this baffle, the coolant enters from the inlet pipe 9 and flows to the core through multiple baffle ports 2 on the baffle base plate 1. Simulation calculations show that... Figure 3 The simulation cloud diagram of the flow resistance performance of the novel baffle plate in this water-cooled intercooler is shown in the figure. The maximum pressure drop is 8620 Pa. Figure 4 The simulation cloud diagram of the flow resistance performance of a typical spoiler is shown, with a maximum pressure drop of 8800 Pa, representing a 2% improvement compared to the previous version; as shown in the figure.

Figure 6 The diagram shown is a simulation cloud map of the temperature performance of a typical spoiler, which has no impact on its temperature performance.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
