[0002] In the field of new energy technology, the electric drive axle, as an integrated powertrain component for electric vehicles, integrates the drive motor, reducer, and axle, reducing the number of powertrain components and optimizing the overall vehicle structure. However, the integration level of the traditional electric drive axle structure is nearing saturation. The filter press and heat exchanger mounted on the electric drive axle are both large in size, requiring considerable space and difficult to arrange rationally. Furthermore, the filter press and heat exchanger require separate mounting devices, resulting in a large number of components needed to produce the electric drive axle and higher costs. Summary of the Invention

[0033] See Figure 1 and Figures 4 to 8 , Figure 1 and Figures 4 to 8Schematic diagrams of the heat exchange components in four embodiments of this application are shown. This application provides a heat exchange component, including a heat exchanger 1 and a filter 2. The heat exchanger 1 includes a substrate 11 and a heat exchange core 12. The heat exchange core 12 includes an inlet (not shown) and an outlet (not shown). The substrate 11 includes a first surface 111, a second surface 112, and a first connecting channel 113. The first surface 111 and the second surface 112 are opposite sides of the substrate 11 in the thickness direction. The heat exchange core 12 is disposed on the first surface 111, and one end of the first connecting channel 113 is fluidly connected to the inlet or outlet of the heat exchange core 12. The filter 2 is disposed on the first surface 111 or the second surface 112, and the other end of the first connecting channel 113 is fluidly connected to the filter 2. The filter 2 is used to filter the heat exchange fluid flowing through the first connecting channel 113.

[0034] The heat exchange assembly provided in this application has a heat exchange core 12 disposed on the first surface 111 of a substrate 11, and a filter 2 integratedly disposed on either the first surface 111 or the second surface 112 of the substrate 11, and connected to the heat exchange core 12 and the filter 2 via a first connecting channel 113. This heat exchange assembly can both exchange heat with the heat exchange fluid through the heat exchange core 12 and filter impurities from the heat exchange fluid through the filter 2. This heat exchange assembly saves space required for installing the heat exchanger 1 and the filter 2, making it suitable even in compact spaces. Furthermore, the filter 2 is integrated into the cover plate 1, eliminating the need for upper and lower covers and other components for fixing the filter element, thus saving materials and reducing production costs.

[0035] In this application, the heat exchange assembly is used in an automobile engine, and the heat exchange fluid is engine oil. The engine oil is filtered by a filter 2, and the heat exchange core 12 cools the engine oil, allowing it to continuously provide cooling to the engine and maintain its normal operating condition. Of course, this heat exchange assembly can also be used in other engines, and the heat exchange fluid is not limited to engine oil.

[0036] In some embodiments, the first connecting channel 113 is in fluid communication with the outlet of the heat exchange core 12. In this case, the heat exchange fluid first flows through the heat exchange core 12, and after being subjected to the heat exchange effect of the heat exchange core 12, it flows through the first connecting channel 113 to reach the filter 2, and is then subjected to the filtration effect of the filter 2.

[0037] Of course, the first connecting channel 113 can also be fluidly connected to the inlet of the heat exchange core 12. In this case, the flow direction of the heat exchange fluid is opposite to that in the embodiment where "the first connecting channel 113 is fluidly connected to the outlet of the heat exchange core 12". The heat exchange fluid first flows through the filter 2, and after being filtered by the filter 2, it flows through the first connecting channel 113 and enters the heat exchange core 12 from the inlet for heat exchange.

[0038] Continue to refer to Figures 1 to 8 The filter 2 of this application includes a housing 21 and a filter element 22. The filter housing, i.e., the outer casing 21, is interconnected with the substrate 11 to jointly define the cavity of the filter. Figure 1 and Figure 2 For example, the outer casing 21 is connected to the second surface 112 of the substrate 11. More specifically, an opening is formed on one side of the outer casing 21, and the second surface 112 of the substrate 11 covers the opening, making the internal space of the outer casing 21 closed. That is, the outer casing 21 and the substrate 11 together define the cavity formed by the filter 2, i.e., the filter cavity. The filter element 22 is disposed in the filter cavity to divide the filter cavity into a clean side and a dirty side. After the heat exchange fluid enters the filter 2, the heat exchange fluid will flow from the dirty side to the clean side in the filter cavity. During this process, the filter element 22 filters out impurities in the heat exchange fluid. When one end of the first connecting channel 113 is connected to the inlet of the heat exchange core, the other end of the first connecting channel 113 is connected to the clean side; when one end of the first connecting channel 113 is connected to the outlet of the heat exchange core, the other end of the first connecting channel 113 is connected to the dirty side.

[0039] In some embodiments, the housing 21 is a plastic housing, and the housing 21 includes a connecting flange 210 formed on the side facing the substrate 11. The heat exchange assembly also includes a welding ring (not shown), which is made of a material that can be welded to the substrate 11. The welding ring is pressed against the connecting flange 210 and welded to the substrate 11, thereby connecting the housing 21 to the substrate 11. Specifically, refer to Figure 1 , Figure 4 , Figure 5 and Figure 7 In different embodiments of this application, the outer shell 21 is provided with a connecting flange 210, which is formed by protruding outward along the edge of the outer shell 21. By providing a connecting flange 210 on the outer shell 21, the welding ring and the outer shell 21 have sufficient contact area, which improves the pressing and fixing effect, thereby improving the connection stability between the outer shell 21 and the substrate 11.

[0040] Furthermore, the material of the welding ring can be the same as that of the substrate 11, which improves the welding compatibility between the welding ring and the substrate 11, and consequently, the welding ring and the substrate 11 are more stable after welding.

[0041] Furthermore, both the welding ring and the substrate 11 are made of aluminum alloy. Aluminum alloy exhibits good adaptability to the welding process. Due to its low melting point and excellent physical properties, aluminum alloy can quickly reach the appropriate melting temperature during welding, ensuring the uniformity and integrity of the weld. In addition, aluminum alloy generates a small heat-affected zone during welding, which can effectively reduce welding deformation and residual stress, thereby improving weld quality.

[0042] In some embodiments of this application, the welding ring and the substrate 11 are welded by laser welding. Laser welding has high welding efficiency and relatively fast welding speed, and generates less heat per unit time, which can reduce the deformation of the substrate 11, thereby improving the connection stability between the substrate 11 and the welding ring, and helping the filter element 22 and the heat exchange core 12 to maintain a stable state and operate stably. In other embodiments, the welding ring and the substrate 11 can also be welded by other welding methods such as ultrasonic welding, or connected by means of bonding, riveting, or screw connection, etc., and this application does not limit this.

[0043] In some embodiments of this application, the heat exchange assembly is an oil cooler assembly, in which cooling oil continuously flows within the heat exchange core 12 to cool the heat exchange fluid. The embodiments described below are all based on the example of the first connecting channel 113 fluidly communicating with the inlet of the heat exchange core 12.

[0044] refer to Figure 1 and Figure 4 An oil inlet 211 is provided on the side of the housing 21 away from the substrate 11. Unfiltered engine oil enters the dirty side of the filter press chamber through the oil inlet 211, and is then filtered by the filter element 22. In other embodiments, the oil inlet 211 may also be provided at other locations on the housing 21. Optionally, refer to... Figure 5 and Figure 7 An oil inlet bend 212 is added to the oil inlet 211 to connect oil supply pipes and other oil supply accessories, so as to guide unfiltered oil to the oil inlet 211.

[0045] An oil outlet (not shown) is provided on the side of the outer shell 21 of the filter element 22 near the substrate 11, and the oil outlet is connected to the clean side of the filter chamber. After being filtered by the filter element 22, the oil flows out of the filter 2 through the oil outlet. The substrate 11 is provided with a first oil passage 13 (shown as a dashed hole because the first oil passage 13 is blocked by the outer shell 21) and a second oil passage 14. In the embodiment described herein, the first connecting channel 113 exists as a through hole penetrating the substrate 11, i.e., the first oil passage 13. Both the first oil passage 13 and the second oil passage 14 penetrate the substrate 11 along the thickness direction of the substrate 11. The oil outlet is in fluid communication with the first oil passage 13, so that the oil filtered by the filter element 22 can pass through the substrate 11 along the direction from the second surface 112 to the first surface 111 through the first oil passage 13 and reach the heat exchange core 12. The second oil passage 14 is connected to the outlet fluid of the heat exchange core 12, so that the heat exchange fluid after heat exchange by the heat exchange core 12 can flow out to the outside of the heat exchange assembly through the second oil passage 14.

[0046] Of course, the extension direction of the first oil passage 13 and the second oil passage 14 can also be at a certain angle to the thickness direction of the substrate 11, rather than having to be parallel to the thickness direction of the substrate 11. This application does not impose any restrictions on this.

[0047] In some embodiments of this application, the filter element 22 is manufactured using a flat folding process. (See reference...) Figure 2 Specifically, the filter element 22 has a flat shape with a certain thickness and width, facilitating installation within the rectangular housing 21. The filter element 22 fits tightly against the inner wall of the filter, ensuring uniform fluid flow during filtration and reducing the risk of short-circuit flow and leakage. Furthermore, the filter element 22 employs a folded design, folding the filter paper into multiple layers to form an accordion or folding fan shape, significantly increasing the filtration area. Within the same volume, the filtration area of ​​the folded filter element 22 can be several times or even tens of times larger than that of a traditional flat filter element 22, thereby improving filtration efficiency and dirt-holding capacity.

[0048] In other embodiments of this application, reference is made to Figure 3 The filter element 22 has a cylindrical shape and also adopts a folded design, which increases the filtration area and improves filtration efficiency and dirt holding capacity.

[0049] In some embodiments of this application, the filter element 22 includes a support 222 and a filter paper element 223. (See reference...) Figure 2 , Figure 2 The structure of the filter element 22 in some embodiments of this application is shown. The support 222 includes a base plate (obscured and not shown) and two baffles 2221. The base plate is approximately rectangular and flat, and the two baffles 2221 are respectively disposed on the two long edges of the base plate, forming an approximately rectangular groove structure. A plurality of partitions 2222 are also spaced apart between the two baffles 2221. Figure 2 In the embodiment shown, there are two partitions 2222. The two partitions 2222 and the baffle 2221 are approximately the same height and length. The two partitions 2222 divide the square groove structure formed by the bracket 222 into three installation spaces. Multiple filter paper pieces 223 are arranged at intervals in each installation space. The filter paper pieces 223 adopt a folded design, and each filter paper piece 223 has a multi-layer structure.

[0050] The filter element 22 includes a sealing edge 221, which is sandwiched between the housing 21 and the substrate 11. For example, see reference... Figure 2 or Figure 3 The sealing edge 221 is provided around the outer edge of the bottom of the filter element 22. When the filter element 22 is installed in the filter chamber, the sealing edge 221 is sandwiched between the housing 21 and the substrate 11 to optimize the fixation effect of the filter element 22 in the filter chamber.

[0051] The heat exchange core 12 is disposed on the first surface 111 and is approximately square. Both end faces of the heat exchange core 12 are approximately square, and one end face is connected to the first surface 111 to fix the heat exchange core 12 to the substrate 11, enabling stable operation. In the various embodiments listed in this application, similar to the connection between the outer casing 21 and the substrate 11, the heat exchange core 12 and the first surface 111 of the substrate 11 are also fixedly connected by laser welding.

[0052] Continue to refer to Figure 1 and Figures 4 to 8 An oil passage (not shown) is provided inside the heat exchange core 12. The two ends of the oil passage are the inlet and outlet, respectively, which are also the inlet and outlet of the heat exchange core 12. Optionally, the inlet of the oil passage is located on the end face of the heat exchange core 12 near the substrate 11, and the inlet of the oil passage is directly connected to the first oil passage through-hole 13 to form fluid communication. Thus, the engine oil filtered by the filter 2 enters the oil passage, and its temperature decreases under the cooling effect of the heat exchange core 12, so that when the oil flows out of the oil passage, its temperature drops to a range that can effectively cool the engine. The outlet of the oil passage is directly connected to the second oil passage through-hole 14 to form fluid communication. Thus, the engine oil enters the heat exchange core 12 through the first oil passage through-hole 13, is cooled by the heat exchange core 12, and then leaves the heat exchange core 12 through the second oil passage through-hole 14. Optionally, an oil pipe connector (not shown) is added to the second surface 112 to connect to the second oil passage 14, so that the oil pipe connector can be connected to oil supply pipes and other oil supply accessories to guide the cooled engine oil to the engine or other parts that need to be cooled.

[0053] The heat exchange core 12 has a coolant channel (not shown in the figure), with a coolant inlet (not shown in the figure) and a coolant outlet (not shown in the figure) at its two ends. The coolant inlet is located on the end face of the heat exchange core 12 away from the substrate 11. (Reference) Figures 5 to 8 To facilitate the connection between the heat exchange core 12 and the pipeline (not shown) for circulating coolant, a coolant connector 18 is provided at the coolant inlet. The pipeline (not shown) for circulating coolant can be snapped or screwed onto the coolant connector 18, offering high convenience. In this embodiment, the coolant connector 18 is a straight connector. Of course, in some other embodiments, the coolant connector 18 can also be a bend connector; this application does not limit the type of coolant connector 18. The coolant outlet is located on the end face of the filter 2 near the substrate 11. Therefore, the coolant enters the coolant channel through the coolant inlet, absorbs heat from the oil in the oil passage, and then flows out of the heat exchange core 12 through the coolant outlet.

[0054] Furthermore, the substrate 11 is also provided with a coolant through-hole 15. Exemplarily, the coolant through-hole 15 penetrates the substrate 11 along its thickness direction; that is, the two ends of the coolant through-hole 15 are located on the first surface 111 and the second surface 112, respectively. The coolant inlet is connected to the coolant through-hole 15, allowing coolant to enter the cooler channel through the end of the coolant through-hole 15 located on the second surface 112.

[0055] The following are several typical embodiments of this application. The placement of the filter 2 and the shape of the filter element 22 differ in each embodiment, as detailed below:

[0056] Example 1:

[0057] In this embodiment, the filter 2 is disposed on the second surface 112. In an exemplary embodiment, such as Figure 1 As shown, the substrate 11 is approximately square in shape. The heat exchange core 12 and the filter 2 are located on one of the two opposing surfaces of the substrate 11. That is, the heat exchange core 12 is disposed on the first surface 111 and the filter 2 is disposed on the second surface 112.

[0058] In this embodiment, the filter 2 covers the first oil passage 13, and the first oil passage 13 is connected to the filter press chamber. For example, refer to... Figure 1 Understandably, the two ends of the first oil passage 13 are located on the first surface 111 and the second surface 112, respectively, and one end of the first oil passage 13 is covered by the heat exchange core 12, so that the inlet of the heat exchange core 12 is aligned with and directly connected to the end of the first oil passage 13 located on the first surface 111. This eliminates the need for connecting oil pipes or other oil supply accessories, allowing filtered oil to directly enter the heat exchange core 12 through the first oil passage 13, reducing the number of accessories used, lowering production costs, and reducing the complexity of the overall structure. The other end of the first oil passage 13 is located on the second surface 112 and is covered by the filter 2, allowing the oil outlet to be directly aligned with and connected to the end of the first oil passage 13 located on the second surface 112, so that oil flows into the first connecting channel 113 from the clean side.

[0059] In this embodiment, the substrate 11 includes a main body 171 and an extension 172. For example... Figure 1 As shown, the main body 171 is approximately square in shape, and the extension 172 is located on one side edge of the main body 171 and protrudes outward. The main body 171 and the extension 172 can be integrally formed. For ease of understanding, in Figure 1A dashed line is used as a virtual boundary between the two. Understandably, the entire heat exchange core 12 is mounted on the main body 171, while only a portion of the filter 2 is mounted on the main body 171, with the other portion mounted on the extension 172. Thus, by changing the shape and outward protrusion distance of the extension 172, it can be ensured that the edges of the outer casing 21 can be connected to the substrate 11, avoiding the length of the filter 2 being limited by the size of the main body 171, and ensuring good welding results.

[0060] Example 2

[0061] refer to Figure 3 and Figure 4 In this embodiment, the structure of the heat exchange assembly is largely the same as that described in Embodiment 1. The difference is that the outer shell 21 of the heat exchange assembly in this embodiment is a hollow cylinder, one end of which is open and covered by the substrate 11. The filter element 22 has a cylindrical shape and is coaxially arranged with the outer shell 21. As shown in the figure, the central axis of the filter 2 is offset on the substrate 11 to avoid the coolant through hole 15 and the second oil passage through hole 14. In addition, the substrate 11 does not have an extension 172.

[0062] Example 3

[0063] refer to Figure 5 and Figure 6 In this embodiment, the substrate 11 is approximately rectangular. The filter 2 is disposed on the first surface 111, that is, the filter 2 and the heat exchange core 12 are disposed on the same side of the substrate 11.

[0064] One end of the first connecting channel 113 is located on the first surface 111 and is covered by the heat exchange core 12, so that the inlet of the heat exchange core 12 is aligned with and directly connected to the end of the first connecting channel 113 located on the first surface 111.

[0065] In this embodiment, the heat exchange assembly further includes a second connecting channel 114, which penetrates the substrate 11 and connects the first connecting channel 113 and the filter 2. Specifically, the second connecting channel 114 exists in the form of a third oil passage 16, which penetrates the substrate 11 along its thickness direction, with the clean side connected to the third oil passage 16. Specifically, the filter 2 covers one end of the third oil passage 16 located on the first surface 111, allowing the oil outlet to be directly connected to the third oil passage 16 to form fluid communication, eliminating the need for connection through an oil pipe or other oil supply fittings, thus reducing the number of fittings used and lowering costs.

[0066] Of course, the third oil passage through-hole 16 is at a certain angle to the thickness direction of the substrate 11, but it does not have to be parallel to the thickness direction of the substrate 11. This application does not impose any restrictions on this.

[0067] The third oil passage 16 and the first oil passage 13 are connected on the side of the second surface 112 via an oil supply pipe (not shown) or other oil supply accessories. This allows the oil filtered by the filter 2 to flow out through the third oil passage 16 and then enter the heat exchange channel of the heat exchange core 12 through the first oil passage 13 for cooling. In this embodiment, since the oil supply pipe (not shown) and other oil supply accessories are only located on the side of the substrate 11 away from the filter 2 and the heat exchange core 12, the oil supply pipe and other oil supply accessories are effectively separated from the filter 2 and the heat exchange core 12, preventing oil leakage caused by accidental collision. In other embodiments, a flow channel plate can be added to the second surface 112 of the substrate 11. The connecting channels in the flow channel plate can fluidly connect the first oil passage 13 and the third oil passage 16, that is, fluidly connect the first connecting channel 113 and the second connecting channel 114.

[0068] The difference between Example 3 and Examples 1 or 2 also includes: an oil inlet bend 212 is provided at the location of the oil inlet 211 (not shown due to obstruction). The oil inlet bend 212 is used to connect to the oil supply pipe or other oil supply accessories to guide unfiltered oil into the filter press chamber. In this example, the oil inlet bend 212 is a bend connector. In other examples not listed, the oil inlet bend 212 may also be a straight connector or other types of connectors.

[0069] Example 4

[0070] refer to Figure 7 and Figure 8 In this embodiment, the structure of the heat exchange component is roughly the same as that of the heat exchange component described in Embodiment 3. The difference is that the outer shell 21 of the heat exchange component in this application is hollow cylindrical, one end of the outer shell 21 is open and covered by the substrate 11, and the filter element 22 has a cylindrical shape and is coaxially arranged with the outer shell 21.

[0071] In the above embodiment, the first oil passage through-hole 13, the second oil passage through-hole 14, and the coolant through-hole 15 are arranged in a right-angled triangle on the substrate 11. (See reference...) Figure 1 , Figure 4 , Figure 6 and Figure 8 In this configuration, the first oil passage 13, the second oil passage 14, and the coolant passage 15 are each positioned opposite one corner of the end face of the heat exchange core 12, with the second oil passage 14 located at the right angle of the right triangle formed by the three passages. This effectively prevents interference between the oil pipe connectors (not shown) and other oil supply fittings connected to the first oil passage 13, the second oil passage 14, and the coolant passage 15. Of course, the relative positions of the first oil passage 13, the second oil passage 14, and the coolant passage 15 on the substrate 11 can also be in other shapes, not limited to a right triangle.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
