Detailed Implementation

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0028] refer to Figure 1 and Figure 2 This application provides an oil cooler assembly 100 for cooling oil in a component to be cooled, the component including a housing (not shown). The component to be cooled can be a vehicle's transmission. Specifically, the oil cooler assembly 100 can cool the oil inside the transmission housing. Transmissions are widely used in vehicles and can also be used in other industrial equipment.

[0029] The oil cooler assembly 100 includes a housing 200 and a bypass pipe 300. One side of the housing 200 is mounted to the outer wall of a housing, and the bypass pipe 300 is located on the other side of the housing 200. In some embodiments, the housing 200 includes a connecting wall 201 and an enclosure 202 fixedly connected together, forming a receiving cavity. The receiving cavity is provided with a first channel 203, a second channel 204, and a third channel 205. The first channel 203 communicates with the interior of the housing, the third channel 205 is used for oil heat exchange, and the second channel 204 communicates with the interior of the housing. The first channel 203 and the second channel 204 are spaced apart along the length of the housing 200, and the extending directions of the first channel 203 and the second channel 204 are parallel to the height direction of the housing 200, which is also the direction in which the housing 200 points towards the housing.

[0030] There are multiple third channels 205, and the extension direction of the third channels 205 is perpendicular to the height direction of the outer shell 200. The height direction refers to the arrangement direction of the housing and the outer shell 200. The multiple third channels 205 are arranged at intervals along the height direction of the outer shell 200, and a cooling channel is provided between any two adjacent third channels 205. That is, multiple cooling channels and multiple third channels 205 are arranged alternately along the height direction of the outer shell 200. The multiple cooling channels are interconnected and contain coolant such as water. The coolant can exchange heat with the oil to cool the oil. One end of each of the multiple third channels 205 is connected to the first channel 203, and the other end of each of the multiple third channels 205 is connected to the second channel 204.

[0031] For details, please refer to Figure 3 The cavity contains multiple first cooling plates 215 and multiple second cooling plates 216, which are alternately stacked along the height of the outer shell. It can be understood that the first cooling plates 215 and second cooling plates 216 are in contact with each other without gaps. Both the first cooling plates 215 and second cooling plates 216 can be channels formed by stacking upper and lower plates along the height of the outer shell. The gap between the upper and lower plates of the first cooling plate 215 is the third channel 205. The gap between the upper and lower plates of the second cooling plate 216 is the cooling channel.

[0032] In other embodiments, the first cooling plate 215 and the second cooling plate 216 may share a single sheet material. For example, the first cooling plate 215 may be stacked on top of the second cooling plate 216, and the lower layer of the first cooling plate 215 and the upper layer of the second cooling plate 216 may be made of the same sheet material. This reduces the amount of sheet material used, saves materials, and reduces the distance between the third channel and the cooling channel, allowing for sufficient heat exchange between the coolant and the oil.

[0033] The cavity also contains a first cylindrical member 217 and a second cylindrical member 218. A first channel 203 is located in the first cylindrical member 217, and a second channel 204 is located in the second cylindrical member 218. The first cylindrical member 217 penetrates through the first cooling plate 215 and the second cooling plate 216. The interior of the first cylindrical member 217 communicates only with the interior of the first cooling plate 215, thus connecting the third channel 205 and the first channel 203. The interior of the first cylindrical member 217 is separated from the interior of the second cooling plate 216, thus isolating the third channel 205 from the cooling channel. Similarly, the second cylindrical member 218 penetrates through the first cooling plate 215 and the second cooling plate 216. The interior of the second cylindrical member 218 communicates only with the interior of the first cooling plate 215, thus connecting the third channel 205 and the second channel 204. The interior of the second cylindrical member 218 is separated from the interior of the second cooling plate 216, thus isolating the third channel 205 from the cooling channel.

[0034] The connecting wall 201 contacts the housing, and the enclosure 202 protrudes relative to the housing; the bypass pipe 300 is located on the side of the enclosure 202 away from the receiving cavity. (Reference) Figure 2 When the bypass line 300 is closed, the first channel 203, the third channel 205, and the second channel 204 form a loop. Specifically, under normal vehicle operating conditions, if the oil temperature is high, the bypass line 300 is closed. At this time, the oil flows from the tank sequentially to the first channel 203, the third channel 205, and the second channel 204, and then flows back to the tank from the second channel 204. As the oil passes through the first channel 203, the third channel 205, and the second channel 204, the cooling liquid in the cooling channels inside the housing can cool the oil flowing in the third channel 205. The cooled oil then returns to the tank, allowing it to flow back into the tank from the second channel 204 to lubricate and cool the working devices inside the tank.

[0035] refer to Figure 4 When the bypass line 300 is opened, the first channel 203, the bypass line 300, and the second channel 204 form a loop. Specifically, for example, during a low-temperature start-up, if the fluid temperature is low, the bypass line 300 opens, and most of the fluid flows sequentially from the tank to the first channel 203, the bypass line 300, and the second channel 204, before returning to the tank from the second channel 204. That is, most of the fluid does not need to pass through the third channel 205, but instead enters the bypass line 300 directly through the first channel 203 and returns to the tank from the second channel 204. Of course, a small portion of the fluid also flows back to the inside of the tank via the first channel 203, the third channel 205, and the second channel 204. The fluid flows within the tank, exchanging heat with the working devices inside, and the fluid temperature gradually increases.

[0036] Of course, if the third channel 205 becomes blocked, the bypass line 300 can be opened, allowing the oil to flow directly into the bypass line 300 through the first channel 203, and then return to the tank through the second channel 204. This prevents damage to the hydraulic system due to blocked oil flow.

[0037] When the bypass pipe 300 is open, most of the oil flows back into the housing from the first channel 203, the bypass pipe 300, and the second channel 204, while a small portion flows back into the housing from the first channel 203, the third channel 205, and the second channel 204. This is because the diameter of the bypass pipe 301 is larger than the cross-sectional area of ​​the first cooling plate 215, resulting in greater flow resistance in the third channel 205 and less flow resistance in the bypass pipe 300.

[0038] As can be seen from the above, in this embodiment, the oil is cooled by an oil cooler, thus lowering the oil temperature. By providing a bypass pipe 300, the oil temperature gradually rises to a suitable level without further cooling. This achieves oil temperature regulation, keeping the oil temperature within a suitable range for the transmission's operation and preventing the oil temperature from affecting the transmission's efficiency.

[0039] In addition, the oil cooler is installed on the enclosure 202, which is located outside the housing. The bypass pipe 300 is then connected to the outside of the enclosure 202, thus placing the bypass pipe 300 outside the housing. This design avoids occupying internal space within the housing and increases the flexibility of the oil cooler's placement, reducing the difficulty of its installation and design.

[0040] In some embodiments, reference is made to Figure 1 The inner side of the connecting wall 201 is fitted against the outer wall of the housing. The enclosure 202 is installed on the outer side of the connecting wall 201. The enclosure 202 includes a first enclosure wall 207 and a second enclosure wall 208. Along the height direction of the outer shell 200, that is, in the direction from the outer shell 200 to the housing, the outer sides of the first enclosure wall 207 and the connecting wall 201 are opposite each other, and the second enclosure wall 208 is connected between the first enclosure wall 207 and the connecting wall 201. The first channel 203, the second channel 204, and the third channel 205 are all formed within the space enclosed by the connecting wall 201, the first enclosure wall 207, and the second enclosure wall 208. The first channel 203, the second channel 204, and the third channel 205 are all built into the enclosure 202, which can improve the structural integration inside the outer shell 200 while improving the heat exchange effect.

[0041] The bypass pipe 300 can be disposed in the first enclosing wall 207, or the bypass pipe 300 can also be disposed in the second enclosing wall 208. Specifically, the outer shell 200 is cuboid in shape. The second enclosing wall 208 includes a first side wall 209, a second side wall 210, a third side wall 211, and a fourth side wall 212. The first side wall 209 and the second side wall 210 are opposite each other along the length direction of the outer shell 200, and the third side wall 211 and the fourth side wall 212 are opposite each other along the width direction of the outer shell 200. The first side wall 209, the third side wall 211, the second side wall 210, and the fourth side wall 212 are connected end to end in sequence. The first enclosing wall 207 and the connecting wall 201 are fixed to opposite sides of the second enclosing wall 208, and the first enclosing wall 207, the second enclosing wall 208, and the connecting wall 201 enclose a receiving cavity. The bypass pipe 300 can be installed on any one of the first side wall 209, the second side wall 210, the third side wall 211, or the fourth side wall 212. Therefore, the location of the bypass pipe 300 offers a wide range of options and high design flexibility.

[0042] The bypass pipe 300 can be connected to the first enclosure wall 207 or the second enclosure wall 208 by welding, bolting, or other connection methods. Preferably, the bypass pipe 300 is connected to the first enclosure wall 207, which facilitates the installation of the bypass pipe 300 by using the connecting wall 201 for positioning.

[0043] In some embodiments, reference is made to Figure 1 , Figure 2 and Figure 5 The bypass pipeline 300 includes a pipe 301 and a valve core 302, the valve core 302 being provided with a connecting hole 303; both ends of the pipe 301 are connected to the other side of the outer casing. One end of the pipe 301 is connected to the first channel 203, and the other end of the pipe 301 is connected to the second channel 204.

[0044] Specifically, one end of the pipe 301 is connected to either the first enclosing wall 207 or the second enclosing wall 208, and the other end of the pipe 301 is also connected to either the first enclosing wall 207 or the second enclosing wall 208. It can be understood that the first enclosing wall 207 or the second enclosing wall 208 is provided with a first connecting hole 213 and a second connecting hole 214, respectively, and both ends of the pipe 301 can pass through the first connecting hole 213 and the second connecting hole 214, respectively, and extend into the receiving cavity. Alternatively, both ends of the pipe 301 are opposite to the first connecting hole 213 and the second connecting hole 214, respectively, such that one end of the pipe 301 communicates with the first channel 203 through the first connecting hole 213, and the other end of the pipe 301 communicates with the second channel 204 through the second connecting hole 214. The pipe 301 can be fixed to the first enclosing wall 207 or the second enclosing wall 208 by welding or other methods.

[0045] The valve core 302 is rotatably disposed inside the pipe 301. When the valve core 302 is rotated until both ends of the connecting hole 303 are connected to the inside of the pipe 301, the bypass pipe 300 is opened; when the valve core 302 is rotated until both ends of the connecting hole 303 are opposite to the inner wall surface of the pipe 301, the bypass pipe 300 is closed. By rotating the valve core 302, the bypass pipe 300 can be opened and closed. The structure is simple and easy to operate.

[0046] Understandable, for reference Figure 2 The connecting wall 201 is provided with a first mating hole 2011 and a second mating hole 2012. The first mating hole 2011 is connected to the end of the first channel 203 away from the first connecting hole 213, and the second mating hole 2012 is connected to the end of the second channel 204 away from the second connecting hole 214. Along the height direction of the outer shell 200, the axis of the first mating hole 2011 coincides with the axis of the first connecting hole 213, and the axis of the second mating hole 2012 coincides with the axis of the second connecting hole 214. This facilitates processing.

[0047] In some embodiments, reference is made to Figure 1The pipeline 301 includes a first part 304, a second part 305, and a third part 306 that are fixedly connected in sequence. The second part 305 is cylindrical. The first part 304 and the third part 306 are respectively connected to the outer peripheral wall of the second part 305. The valve core 302 is installed inside the second part 305 and has a columnar structure that is adapted to the second part 305. The valve core 302 can rotate around its axis to open or close the bypass pipeline 300.

[0048] Specifically, the first part 304 and the third part 306 have the same axial direction, while the axial direction of the second part 305 can be perpendicular to the axial direction of the first part 304. The first part 304 has a first bend 307 at the end furthest from the second part 305. The third part 306 has a second bend 308 at the end furthest from the second part 305. The first bend 307 and the second bend 308 are respectively connected to the first connecting hole 213 and the second connecting hole 214. The first bend 307, the first part 304, the second part 305, the third part 306, and the second bend 308 are sequentially fixedly connected. The first bend 307 and the first part 304, the first part 304 and the second part 305, the second part 305 and the third part 306, and the third part 306 and the second bend 308 can all be integrally formed, or formed separately and then fixedly connected by welding or other methods. Therefore, the pipe 301 has a compact structure and is easy to connect to the outer casing 200 and the valve core 302.

[0049] refer to Figure 1 and Figure 5 The valve core 302 is cylindrical, and the connecting hole 303 penetrates the valve core 302 radially. The valve core 302 is located inside the second part 305, and the valve core 302 and the second part 305 are axially aligned. When the valve core 302 rotates to the point where both ends of the connecting hole 303 are connected to the first part 304 and the third part 306 respectively, the bypass pipe 300 is opened. When the valve core 302 rotates to the point where both ends of the connecting hole 303 are opposite to the inner wall surface of the second part 305, the connecting hole 303 is closed by the inner wall surface of the second part 305, and the bypass pipe 300 is closed.

[0050] The valve core 302 is cylindrical, and the second part 305 is cylindrical. This design facilitates the rotation of the valve core 302 and allows the bypass pipeline 300 to be opened or closed by utilizing the interaction between the valve core 302 and the second part 305. The structure is simple, easy to operate, and highly reliable.

[0051] In some embodiments, the valve core 302 can be spherical, and the second part is a spherical shell adapted to the valve core 302. The valve core 302 has a through hole 303 extending along the diameter direction of the valve core 302. When the valve core 302 rotates to the point where the two ends of the through hole 303 are connected to the first part 304 and the third part 306 respectively, the bypass pipe 300 is opened. When the valve core 302 rotates to the point where the two ends of the through hole 303 are opposite to the inner wall surface of the second part 305, the through hole 303 is closed by the inner wall surface of the second part 305, and the bypass pipe 300 is closed.

[0052] In some embodiments, reference is made to Figure 1 The bypass pipeline 300 also includes an electromagnetic drive source 309, which can be an electromagnet. The electromagnetic drive source 309 is connected to the valve core 302 and is used to control the rotation of the valve core 302. Specifically, a portion of the valve core 302 extends out of the pipeline 301, and the electromagnetic drive source 309 is connected to the portion of the valve core 302 extending out of the pipeline 301. The electromagnetic drive source 309 controls the rotation of the valve core 302, thereby opening or closing the bypass pipeline 300, achieving automated operation with a simple structure and high reliability.

[0053] In some embodiments, reference is made to Figure 1 The first enclosing wall 207 is rectangular. Both ends of the pipe 301 are connected to the first enclosing wall 207. One end of the pipe 301 is connected to the first channel 203, and the other end of the pipe 301 is connected to the second channel 204. The two ends of the pipe 301 are located at two corners of the first enclosing wall 207, which are diagonally distributed. This results in a longer oil flow path, allowing the oil to be fully cooled and improving cooling efficiency. In other words, the first cylindrical component 217 and the second cylindrical component 218 are diagonally distributed.

[0054] In other embodiments, the second enclosing wall 208 is rectangular, and both ends of the pipe 301 are connected to the second enclosing wall 208. The two ends of the pipe 301 are located at two corners of the second enclosing wall 208, which are diagonally distributed.

[0055] In some embodiments, reference is made to Figure 1 and Figure 2 The oil cooler assembly 100 also includes a first connecting pipe 400 and a second connecting pipe 401, both of which are fixed to the outer casing 200.

[0056] Specifically, the first connecting pipe 400 is fixed to the first enclosing wall 207 or the second enclosing wall 208, and the second connecting pipe 401 is fixed to the first enclosing wall 207 or the second enclosing wall 208. One end of both the first connecting pipe 400 and the second connecting pipe 401 communicates with the cooling channel, and the other end of both the first connecting pipe 400 and the second connecting pipe 401 is used to connect to an external coolant tank. Specifically, the first enclosing wall 207 or the second enclosing wall 208 is provided with a third connecting hole and a fourth connecting hole. One end of the first connecting pipe 400 extends into the third connecting hole, or one end of the first connecting pipe 400 is opposite to the third connecting hole, so that the first connecting pipe 400 communicates with the cooling channel through the third connecting hole. One end of the second connecting pipe 401 extends into the fourth connecting hole, or one end of the second connecting pipe 401 is opposite to the fourth connecting hole, so that the second connecting pipe 401 communicates with the cooling channel through the fourth connecting hole.

[0057] The cavity also contains a third cylindrical member 219 and a fourth cylindrical member 220. The third cylindrical member 219 has a first connecting channel, and the fourth cylindrical member 220 has a second connecting channel. The third cylindrical member 219 penetrates through the first cooling plate 215 and the second cooling plate 216, and its interior communicates only with the interior of the second cooling plate 216, thus connecting the first connecting channel and the cooling channel. The interior of the third cylindrical member 219 is separated from the interior of the first cooling plate 215, thus isolating the third channel from the first connecting channel. Similarly, the fourth cylindrical member 220 penetrates through the first cooling plate 215 and the second cooling plate 216, and its interior communicates only with the interior of the second cooling plate 216, thus connecting the second connecting channel and the cooling channel. The interior of the fourth cylindrical member 220 is separated from the interior of the first cooling plate 215, thus isolating the third channel from the second connecting channel.

[0058] The coolant tank contains coolant, which can be a liquid such as water. When the oil cooler is working, the coolant flows from the coolant tank to the first connecting pipe 400, and then from the first connecting pipe 400 through the first connecting channel to the cooling channel, where it exchanges heat with the oil. At this time, the oil temperature decreases and the coolant temperature increases. Then, the cooled coolant flows from the cooling channel through the second connecting channel to the second connecting pipe 401, and then from the second connecting pipe 401 back to the coolant tank.

[0059] In some embodiments, reference is made to Figure 1 The first enclosing wall 207 is rectangular. The first connecting pipe 400 and the second connecting pipe 401 are both connected to the first enclosing wall 207, located at two diagonally opposite corners of the first enclosing wall 207. Correspondingly, the third cylindrical member 219 and the fourth cylindrical member 220 are diagonally distributed. This results in a longer flow path for the coolant, allowing it to effectively cool the oil and improving cooling efficiency.

[0060] In other embodiments, the second enclosing wall 208 is rectangular, and the first connecting pipe 400 and the second connecting pipe 401 are both connected to the second enclosing wall 208. The first connecting pipe 400 and the second connecting pipe 401 are respectively located at two corners of the second enclosing wall 208 that are diagonally distributed.

[0061] It is understandable that if the first connecting pipe 400, the second connecting pipe 401, and the bypass pipe 300 are all connected to the first enclosing wall 207, then the line connecting the two corners where the first connecting pipe 400 and the second connecting pipe 401 are located intersects with the line connecting the two corners where the pipe 301 is located. Similarly, if the first connecting pipe 400, the second connecting pipe 401, and the bypass pipe 300 are all connected to the second enclosing wall 208, then the line connecting the two corners where the first connecting pipe 400 and the second connecting pipe 401 are located intersects with the line connecting the two corners where the pipe 301 is located. On the one hand, this can increase cooling efficiency. On the other hand, the fact that the first connecting pipe 400, the second connecting pipe 401, and the bypass pipe 300 are all connected to the same enclosing wall of the outer casing 200 can increase the structural compactness of the oil cooler assembly 100.

[0063] This application also provides a powertrain, which includes the gearbox assembly provided in the above embodiments. The powertrain can be a fuel system, a hybrid system, or an electric system.

[0064] This application also provides a vehicle, including the powertrain provided in any embodiment of this application. The vehicle can be a gasoline vehicle, a hybrid vehicle, or an electric vehicle.
