[0001] The present application relates to the technical field of auto parts, and in particular to a stacked oil cooler. Background Art

[0002] As a key thermal management component, oil coolers play a vital role in high-performance, high-power engines. With the continuous advancement of engine technology and the improvement of vehicle performance requirements, the design and application of oil coolers have also experienced significant development.

[0003] During the operation of the engine, the oil plays multiple roles such as lubrication, cooling, and cleaning. However, as the engine power and speed increase, the temperature of the oil will also rise accordingly. Excessive oil temperature will not only affect the performance of the oil, but may also cause damage to the engine. Therefore, the emergence of oil coolers has become the key to solving this problem. The oil cooler accelerates the heat dissipation of the lubricating oil to keep it within a low and stable temperature range. It is usually arranged in the lubrication oil circuit of the engine and reduces the temperature of the oil through specific cooling methods such as air cooling or water cooling. The air-cooled oil cooler uses the headwind generated when the car is driving for cooling, while the water-cooled oil cooler uses the circulation of cooling water to control the temperature of the oil.

[0004] It is now found that some oil coolers are large in size, and the large size limits the installation space of this product, and the heat dissipation efficiency per unit volume is low. Therefore, it is necessary to improve this. Utility Model Content

The oil cavities of adjacent inner core components are connected to each other and separated from the external water cavity. The inner core component is annular and has convex points so that adjacent inner core components are supported by the convex points.

[0026] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0027] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. The illustrations only show the components related to the present application rather than being drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0028] The following is combined with Figure 1-5 The specific implementation methods of this application are further described. Example

[0029] The present application embodiment discloses a stacked oil cooler, referring to Figure 1 , Figure 2 and Figure 5 As shown, it includes a shell 1, an inner core assembly 4, an upper cover plate 5, and a lower cover plate 6. The shell 1 is configured to have a top cover portion 11 at the upper end and an opening 12 at the lower end, and the opening 12 allows the inner core assembly 4 to be easily placed therein. The top cover portion 11 can initially limit the inner core assembly 4.

[0030] The side of the housing 1 is connected with a water inlet pipe 2 and a water outlet pipe 3. The water inlet pipe 2 is used to introduce cooling water, and the water outlet pipe 3 is used to discharge the heated water. Through the water circulation, heat exchange is achieved, that is, a cooling effect is brought. This is the effect in the working state.

[0031] The oil cooler is generally hollow cylindrical in shape. The hollow in the middle is a channel 8, which can be used for assembly and allow some pipes on auto parts to penetrate, thereby facilitating installation and fixing, and also cooling (heat exchange) the pipes.

[0032] Returning to the structural scheme of the present application, the upper cover plate 5 is sleeved and fixed on the upper end of the shell 1 for oil inlet, and the lower cover plate 6 is sleeved and fixed on the lower end of the shell 1 for oil outlet.

[0033] For details, please refer to Figure 2 and Figure 3 , multiple inner core components 4 are provided and stacked and fastened between the top cover 11 and the lower cover plate 6 at the upper end of the housing 1, so that the inner cavity of the housing 1 is divided into a water cavity 91 and an oil cavity 92. The oil cavities 92 of adjacent inner core components 4 are connected to each other and separated from the external water cavity 91. The inner core component 4 is annular and has a convex point 413 so that the adjacent inner core components 4 are supported by the convex point 413. The support of the convex point 413 can greatly increase the water flow contact surface.

[0034] Specifically, in Figure 4 In the figure, the inner core component 4 includes an inner core 41, an oil separator 43, an outer core 42 and a fin 44. The inner core 41 has an upward upper flange 411 and the fin 44 is laid inside. The outer core 42 has a downward lower flange 421 and is sleeved and fixed outside the inner core 41. The inner edge of the inner core 41 and the outer core 42 is sealed by the oil separator 43. In other figures, only one fin 44 is shown. In the actual product, each inner core component 4 has a fin 44. The structure of the fin 44 is shown in FIG. Figure 3 As shown, it is formed by punching. This allows the oil to fully contact the fins 44.

[0035] On the other hand, in order to make the assembly more efficient and facilitate positioning and limiting, the inner circle of the inner core 41 is provided with a downward clasp 412, and the clasp 412 of one inner core component 4 limits the position of another inner core component 4 below the inner core component 4 in the stacked state. Figure 2 understand.

[0036] In order to facilitate processing, the convex point 413 is located on the inner chip 41 and is formed by stamping, and a punching groove 414 is formed on the inner surface of the inner chip 41. This effect not only improves the structural strength of the inner chip 41 and can resist deformation, but also increases the contact area between oil and water. The convex point 413 surface contacts water, and the punching groove 414 surface contacts oil.

[0037] In order to facilitate the isolation of oil and water and the installation of the oil separator 43, the inner chip 41 is provided with an annular groove 415 for installing the oil separator 43, and the oil separator 43 is partially embedded in the annular groove 415. This makes it easier to place the oil separator 43, and the oil separator 43 also plays a role in improving the sealing performance.

[0038] Meanwhile, in this solution, a conical plate 51 is provided on the top of the upper cover plate 5, and holes 52 are evenly distributed on the conical surface of the conical plate 51. The inner core component 4 is provided with a plurality of oil ports 45, and the holes 52, the oil ports 45, and the oil chamber 92 are connected. The upper cover plate 5 can be used to reliably receive the engine oil that needs to be cooled, and the engine oil can flow in smoothly from the holes 52.

[0039] In order to improve the reliability of assembly support, a base 7 is also fixed under the lower cover plate 6, and a channel 8 is set in the center of the inner core component 4, and the channel 8 runs through the shell 1, the inner core component 4, the upper cover plate 5, the lower cover plate 6, and the base 7. At this time, the base 7 can provide support during assembly and use, and can protect the lower cover plate 6.

[0040] Finally, in order to ensure efficient and stable water inlet and outlet, the water inlet pipe 2 and the water outlet pipe 3 are at the same height. The water inlet and outlet positions are at the middle height of the housing 1, so that the water inlet and outlet are relatively stable.

[0041] It can be seen that this structural solution has high space utilization, a small and compact structure, and can make full use of the spatial structure to improve the oil cooling efficiency. The oil cooling efficiency is high and water cooling is adopted. It is more efficient than the air cooling solution. In the water cooling solution, water flows in and out through the annular water cavity 91, and the efficiency is very high. Not only is the water contact area large, but the oil contact area is also large, thereby greatly improving the heat exchange efficiency.

[0042] The above embodiments are only illustrative of the principles and effects of the present application, and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application shall be included in the protection scope of the present application.
