Description

Technical Field

[0001] The utility model relates to the technical field of oil coolers, in particular to a novel water-cooled oil cooler with enhanced turbulence and adjustable oil inlet and outlet positions. Background Art

[0002] As the market share of new energy vehicles increases, more and more parts need oil cooling. Common parts of traditional fuel vehicles that need oil cooling include gearboxes and engines. Compared with traditional fuel vehicles, new energy vehicles have increased the demand for oil cooling of motors, electric drives, and electronic controls. Due to the insulation of oil, as the demand for cooling increases, more and more new energy vehicle companies are considering using oil as a cooling medium for further promotion. At the same time, oil coolers are still indispensable for cooling engines and gearboxes of hybrid vehicles.

[0003] Oil coolers can be divided into air-cooled oil coolers and water-cooled oil coolers based on the different oil cooling media. With the popularization of new energy vehicles and the penetration of the concept of vehicle thermal management, water-cooled oil coolers account for an increasingly large proportion because they can participate in the thermal management of the entire vehicle.

[0004] Water-cooled oil coolers are divided into two types: built-in and external. The built-in type is generally integrated in the plastic water chamber of the radiator, and can only be cooled through a large cycle. The external oil cooler is flexible in layout and can be arranged on the frame, and the oil cooler and related cooling components are connected through a special oil pipe; it can also be arranged on the motor drive housing, gearbox housing, engine housing, etc. The oil circuit is directly installed corresponding to the flow channel opening of the relevant cooling component. And it is not limited by large and small cycles. The main engine manufacturer often adopts the external type. The design of the external oil cooler directly arranged on the housing of the relevant cooling component can reduce the oil side pipeline, the corresponding joints, and the sealing gaskets and fasteners used for sealing, which is more popular with the majority of main engines. The present invention is a new type of external oil cooler structure arranged on the housing of the main engine related cooling component.

[0005] The existing external oil cooler structure is an oil cooler arranged on the cooling components related to the host. Its oil inlet and outlet are generally located at the diagonal of the oil cooler plate. Since the oil inlet and outlet need to be connected with the passage on the oil side of the oil cooler core, its adjustment space is very small. It is also impossible to form turbulence during the flow process. When the medium flows along the diagonal, the flow distance is short and the resistance is small. Most of the medium will flow in this direction, resulting in uneven flow and uniform temperature on each flow channel plate, which reduces the heat exchange efficiency. It is very difficult to improve the performance of the oil cooler based on the design of the existing external oil cooler. And for most oil cooler manufacturers with existing oil cooler platforms, the feasibility of borrowing existing platforms is relatively small because the distance between the oil inlet and outlet of the oil cooler on their platform and the oil port on the outer shell of the cooling part related to the host customer is quite different. In response to the demand for cooling components of new host customers, it is often necessary to open a new oil cooler platform, which increases development costs and increases development cycles.

[0006] Chinese patent application No. 202021240144.1 discloses an external water-cooled oil cooler and a car, including: an oil cooler core, on one side of which an inlet pipe mounting hole and an outlet pipe mounting hole are arranged; an inlet pipe, part of which is inserted into the inlet pipe mounting hole; an outlet pipe, part of which is inserted into the outlet pipe mounting hole. When the inlet pipe and the outlet pipe are damaged, they can be repaired by directly replacing the inlet pipe and the outlet pipe, thereby avoiding the problem of resource waste caused by replacing the external water-cooled oil cooler. The existing problem is that when the medium flows along the diagonal, the circulation distance is short and the resistance is small. Most of the medium will flow in this direction, resulting in uneven flow and uniform temperature on each flow channel plate, which reduces the heat exchange efficiency. Similarly, Chinese patent application No. 202320192443.X also has the above problems, so a new water-cooled oil cooler with enhanced turbulence and adjustable inlet and outlet positions is proposed. Utility Model Content

[0007] The technical problem to be solved by the utility model is to overcome the existing defects and provide a new water-cooled oil cooler with enhanced turbulence and adjustable oil inlet and outlet positions, thereby increasing the assemblability of the oil cooler and the oil inlet and outlet ports of the flow channels of the main engine-related components to be cooled; reducing the number of mold openings on the basis of the existing mold platform; increasing the turbulence on each flow channel, increasing the flow uniformity of the medium, avoiding uneven medium flow due to short diagonals, resulting in uneven heat exchange, and improving the heat exchange efficiency of the oil cooler, which can effectively solve the problems in the background technology.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of water-cooled oil cooler with enhanced spoiler and adjustable oil inlet and outlet positions, comprising a core, a top plate and a mounting base, the core being formed by stacking main boards, a center hole being provided at the center of the main board, a spoiler structure being an annular protrusion, a top plate being provided at the upper end of the core, an overflow structure being provided on the top plate, the overflow structure being an overflow protrusion provided on the top plate, and the mounting base being provided at the lower end of the core.

[0009] Furthermore, the flow-through protrusion is formed by stamping, and the flow-through protrusion is configured as a rectangular structure.

[0010] Furthermore, the top plate is fixed to the upper end of the core body by welding, and a water inlet pipe and a water outlet pipe are arranged at the diagonal positions of the top plate.

[0011] Furthermore, an oil inlet and an oil outlet are arranged at the diagonal positions of the mounting base, a spare port is arranged at the center of the mounting base, and mounting holes are arranged around the mounting base.

[0018] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0019] See also Figure 1-3The utility model provides a technical solution: a new type of water-cooled oil cooler with enhanced turbulence and adjustable oil inlet and outlet positions, including a core 6, a top plate 10 and a mounting base 4. The core 6 is formed by stacking main boards 8. The core 6 is a conventional structure. A flow channel is arranged in the core 6, that is, a gap between the main boards 8, a layer of water and a layer of oil, which increases the heat dissipation area. This part is a conventional mechanism and is not described in detail here. A central hole 13 is arranged at the center of the main board 8, and a turbulence structure is arranged at the central hole 13. The turbulence structure is an annular protrusion 7. The annular protrusion 7 enables the stacked core 6 to form a turbulence structure of the internal flow channel, which increases Add a turbulent structure on each flow channel to increase the flow uniformity of the medium, avoid uneven medium flow caused by a short diagonal line, resulting in uneven heat exchange, and improve the heat exchange efficiency of the oil cooler. The top plate 10 is set at the upper end of the core 6, and a flow structure is set on the top plate 10. The flow structure is a flow protrusion 9 set on the top plate 10. The flow protrusion 9 increases the capacity of cooling water entering the core 6 and increases the flow distance of the cooling water. It cooperates with the annular protrusion 7 to play a turbulent role. The cooling water will not flow out directly, and needs to bypass the annular protrusion 7 to play a turbulent role and improve the heat exchange efficiency. The installation base plate seat 4 is set at the lower end of the core 6.

[0020] The flow protrusion 9 is formed by stamping. The flow protrusion 9 is set to a rectangular structure. The flow protrusion 9 forms a groove on the lower surface of the top plate 10 to increase the flow rate of cooling water.

[0021] The top plate 10 is fixed to the upper end of the core 6 by welding, and a water inlet pipe 12 and a water outlet pipe 11 are provided at the diagonal positions of the top plate 10 .

[0022] An oil inlet 2 and an oil outlet 5 are arranged at the diagonal parts of the mounting base plate 4, and a spare port 3 is arranged at the center of the mounting base plate 4, and the spare port 3 can be used as an outlet or an inlet. Through this structure, the installation matching of the spare port 3 of the oil cooler and the oil inlet and outlet of the flow channel of the main machine component to be cooled is increased, the feasibility of the solution of the existing mold platform is increased, the development cost is reduced, and the development cycle is shortened. The mounting base plate 4 is provided with mounting holes 1 around it, and the mounting holes 1 are used to fix the oil cooler.

[0023] The present invention adds a spoiler structure on each main board 8 stacked into a core body 6, so that the stacked core body 6 forms a spoiler structure, and adds a flow structure by stamping on the top plate 10, and adds an intermediate spare oil inlet or spare oil outlet on the bottom plate seat 4; thereby, the oil inlet 2 or oil outlet 5 of the oil cooler is transferred from the diagonal position of the core body 6 to the middle of the core body 6, which greatly improves the position adjustment space of the oil inlet and outlet; makes the oil inlet and outlet arranged on the flow channel of the main machine component to be cooled more compatible; and can improve the utilization rate of existing molds; at the same time, the spoiler structure in the middle of the core body 6 can play a spoiler role on the flowing medium in each flow channel; avoids the shortest diagonal flow route of the core body 6, which causes uneven heat exchange in each flow channel, thereby improving the heat exchange efficiency.

[0024] The basic principles, main features and advantages of the present invention are shown and described above. Without departing from the spirit and scope of the present invention, the present invention may also be subject to various changes and improvements, which are all within the scope of the present invention to be protected.
