[0033] See also Figures 1 to 10 The present invention provides an oil cooler and a vehicle, wherein a first baffle plate 310 is provided in the oil inlet channel 300 to separate the oil inlet channel 300 into a first oil inlet channel 320 and a second oil inlet channel 330, and a second baffle plate 410 is provided in the oil outlet channel 400 to separate the oil outlet channel 400 into a first oil outlet channel 420 and a second oil outlet channel 440. The first oil inlet channel 320, a part of the oil flow channel 100 and the first oil outlet channel 420 form a first oil circuit, and the second oil inlet channel 330, the remaining part of the oil flow channel 100 and the second oil outlet channel 440 form a second oil circuit. The media in the first oil circuit and the second oil circuit are cooled separately by a water circuit, so that one oil cooler can cool the two oil circuits at the same time, thereby solving the problem of needing to install two oil coolers when cooling the motor and transmission of a hybrid vehicle at the same time. One oil cooler can save space, facilitate the overall design, and reduce costs.

[0034] See also Figure 1 、 Figures 8 to 10 In a first aspect, the present invention provides an oil cooler, comprising an oil cooler core, the oil cooler core comprising an oil flow channel 100, a water flow channel 200, a first baffle plate 310, and a second baffle plate 410. The oil flow channel 100 is provided in multiple layers, each of which is connected to an oil inlet channel 300 and an oil outlet channel 400. Lubricating oil flows from the oil inlet channel 300 into the oil flow channel 100, then flows from the oil flow channel 100 to the oil outlet channel 400, and then flows out. The multiple layers of oil flow channels 100 are independently connected in parallel. The water flow channel 200 is provided with multiple layers, and the multiple layers of water flow channels 200 are connected to a water inlet channel 910 and a water outlet channel 920. Cooling water or coolant flows into the water flow channel 200 from the water inlet channel 910, and then flows from the water flow channel 200 to the water outlet channel 920. The multiple layers of water flow channels 200 are independently connected in parallel with each other; the water flow channel 200 and the oil flow channel 100 are arranged in sequence. In other words, along the direction perpendicular to the water flow channel 200, a layer of water channel and a layer of oil channel are arranged in sequence, and then the lubricating oil is cooled by cooling water or coolant, thereby realizing cooling and lubrication of the transmission and the motor. A first baffle plate 310 is disposed within the oil inlet channel 300 to separate the oil inlet channel 300 into a first oil inlet channel 320 and a second oil inlet channel 330. A second baffle plate 410 is disposed within the oil outlet channel 400 to separate the oil outlet channel 400 into a first oil outlet channel 420 and a second oil outlet channel 440. The first oil inlet channel 320 and the first oil outlet channel 420 communicate with the same oil flow channel 100, while the second oil inlet channel 330 and the second oil outlet channel 440 communicate with the same oil flow channel 100. The first oil inlet channel 320, a portion of the upper oil flow channel 100, and the first oil outlet channel 420 communicate to form a first oil channel. The second oil inlet channel 330, the remaining lower oil flow channel 100, and the second oil outlet channel 440 communicate to form a second oil channel. The first and second oil channels are independent of each other, thereby enabling two oil circuits in a single oil cooler to share a single water circuit. The lubricating oil in the two oil circuits can cool and lubricate the motor and transmission, respectively. The two oil channels are connected in parallel, and the water channels 200 in the water circuit are also connected in parallel. A single water pump ensures consistent or substantially consistent heat dissipation efficiency in each layer of the oil channels 100, effectively meeting the heat dissipation requirements of both oil channels. The oil cooler of this utility model not only saves space, facilitating vehicle layout, but also reduces the need for water pumps, meeting heat dissipation requirements, and reducing costs.

[0035] See also Figure 1 and Figure 2In one embodiment of the present invention, the oil cooler includes a first end plate 500 and a second end plate 600. The first end plate 500 is disposed at one end of the oil cooler core and is provided with a first oil inlet 510, a first oil outlet 520, a water inlet 530, and a water outlet 540. The first oil inlet 510 is connected to the first oil inlet channel 320, and the first oil outlet 520 is connected to the first oil outlet channel 420. Lubricating oil enters the first oil inlet channel 320 through the first oil inlet channel 320, then enters the parallel multi-layer oil flow channels 100 through the first oil inlet channel 320, flows into the first oil outlet channel 420, and flows out of the first oil channel through the first oil outlet 520. The water inlet 530 is connected to the water inlet channel 910, and the water outlet 540 is connected to the water outlet channel 920. Cooling water or coolant enters the water inlet channel 910 through the water inlet 530, then enters the parallel water flow channel 200, then enters the water outlet channel 920 from the water flow channel 200, and finally flows out of the water channel through the water outlet 540. The second end plate 600 is disposed at the end of the oil cooler core away from the first end plate 500. The second end plate 600 is provided with a second oil inlet 610 and a second oil outlet 620. The second oil inlet 610 is connected to the second oil inlet channel 330, and the second oil outlet 620 is connected to the second oil outlet channel 440. Lubricating oil enters the second oil inlet channel 330 through the second oil inlet 610, then flows into the oil flow channel 100 connected to the second oil inlet channel 330, then flows to the second oil outlet channel 440, and flows out of the second oil channel through the second oil outlet 620. The inlet and outlet of the first oil passage are arranged on the first end plate 500 , and the inlet and outlet of the second oil passage are arranged on the second end plate 600 , so that the two oil passages are connected to the motor and the transmission respectively.

[0036] Furthermore, the water channel is connected to the vehicle's cooling water tank. The water inlet 530 is connected to the cooling water tank outlet via a water pipe, and the water outlet 540 is connected to the cooling water tank inlet via a water pipe. The cooling water or coolant in the water channel is cooled by the vehicle's cooling water tank to ensure effective heat dissipation to the oil channel. The water pipe includes, but is not limited to, a rubber water pipe.

[0037] See also Figure 1 and Figure 2 In one embodiment of the present invention, the second end plate 600 is provided with a fixing portion 630 having a through-hole 631 extending therethrough. The fixing portion 630 is used to mount the oil cooler, such as to a transmission housing or a vehicle frame. The through-hole 631 accommodates the threaded rod of a connecting bolt, facilitating bolt connection of the oil cooler to its mounting location and facilitating assembly, disassembly, and maintenance of the oil cooler.

[0038] See also Figure 1 and Figure 3 In one embodiment of the present invention, the first oil inlet 510, the first oil outlet 520, the water inlet 530, and the water outlet 540 are disposed at the four corners of the first end plate 500. The first oil inlet 510 and the first oil outlet 520 are arranged diagonally, allowing the lubricating oil to flow from one corner of the oil flow channel 100 to another corner of the oil flow channel 100. This increases the distance the lubricating oil flows and the area of ​​thermal interaction with the water flow channel 200, thereby improving the heat dissipation efficiency of the lubricating oil in the oil flow channel 100. The diagonal arrangement of the water inlet 530 and the water outlet 540 effectively ensures the area through which the cooling water or coolant flows, ensuring effective heat dissipation of the lubricating oil in the oil flow channel 100.

[0039] See also Figure 1 and Figure 3 Furthermore, the first oil inlet 510 and the water inlet 530 are arranged along the length direction of the oil cooler core, and the first oil outlet 520 and the water outlet 540 are arranged along the length direction of the oil cooler core, so that the lubricating oil in the oil flow channel 100 and the cooling water or coolant in the water flow channel 200 cross and counterflow to ensure the heat dissipation efficiency of the lubricating oil.

[0040] See also Figure 6 In one embodiment of the present invention, a guide groove 640 is provided on the side of the second end plate 600 near the oil cooler core. The second oil inlet 610 is disposed within the guide groove 640, and the second oil inlet channel 330 is connected to the guide groove 640. The second end plate 600 is used to mount the oil cooler. When the oil cooler is mounted on a transmission, the second oil inlet 610 and the second oil outlet 620 on the second end plate 600 need to align with the transmission's outlet and inlet, respectively. However, typically, the transmission's inlet and outlet cannot simultaneously align directly with the second oil inlet channel 330 and the second oil outlet channel 440. By providing the guide groove 640 on the second end plate 600, after the second oil inlet 610 aligns with the transmission's outlet, lubricating oil flows through the second oil inlet 610 and the guide groove 640 into the second oil inlet channel 330. This improves the compatibility of the oil cooler, ensures that the lubricating oil in the second oil circuit crosses and counterflows with the cooling water in the water channel, and ensures effective heat dissipation.

[0041] See also Figure 7 Furthermore, sealing grooves are provided at the second oil inlet 610 and the second oil outlet 620. The sealing grooves are used to place sealing rings 650. The sealing rings 650 are used to seal the second oil inlet 610 and the second oil outlet 620 with the outlet and inlet on the transmission housing respectively, thereby reducing the risk of lubricating oil leakage.

[0042] See also Figures 8 to 10In one embodiment of the present invention, the oil cooler core includes a first plate 700 and a second plate 800. The first plate 700 and the second plate 800 are stacked sequentially to form an oil flow channel 100 and a water flow channel 200. The first plate 700 is provided with two first protrusions 710 and two first recesses 720. Each of the first protrusions 710 and the first recesses 720 is provided with a through hole 730 extending through the first plate 700. The second plate 800 is provided with two second protrusions 810 and two second recesses 820. Each of the second protrusions 810 and the second recesses 820 is provided with a through hole 730 extending through the second plate 800. The first plate 700 and the second plate 800 are stacked sequentially to form the oil flow channel 100 and the water flow channel 200. That is, a layer of water flow channel 200 and a layer of oil flow channel 100 are alternately arranged in a direction perpendicular to the first plate 700 or the second plate 800. The first protrusion 710 and the second recess 820 are respectively in contact with each other, so that the through hole 730 on the first plate 700 is connected to the through hole 730 on the second plate 800 to form the oil inlet channel 300 and the oil outlet channel 400. The first recess 720 and the second protrusion 810 are respectively in contact with each other to form the water inlet channel 910 and the water outlet channel 920. For example, if the first protrusion 710 on the first plate 700a is in contact with the second recess 820 on the second plate 800b above it, the lubricating oil will flow directly from the top of the second plate 800b to the bottom of the first plate 700a and will not flow between the first plate 700a and the second plate 800b. If the first protrusion 710 on the first plate 700a is not in contact with the second recess 820 on the second plate 800c below it, the lubricating oil will flow into the oil flow channel between the first plate 700a and the second plate 800c. 100, so that the oil flow channel 100 is above the second plate 800b and the oil flow channel 100 is below the second plate 800c; the first recess 720 on the first plate 700a does not abut the first protrusion 710 on the second plate 800b above, but abuts the second protrusion 810 on the second plate 800c below, then the cooling water will flow into the water flow channel 200 formed between the first plate 700a and the second plate 800b, thereby forming an arrangement in which the water flow channel 200 and the oil flow channel 100 are staggered and stacked.

[0043] Furthermore, a water flow channel 200 is formed between the oil cooler core and the first end plate 500 , so that both sides of the oil flow channel 100 have water flow channels 200 , ensuring that the lubricating oil in the oil flow channel 100 can dissipate heat stably.

[0044] See also Figures 8 to 10In one embodiment of the present invention, the first baffle plate 310 and the second baffle plate 410 are respectively arranged on the two first protrusions 710 of one of the first plates 700 to close the through hole 730 on the first protrusion 710, thereby separating the oil inlet channel 300 into the first oil inlet channel 320 and the second oil inlet channel 330, and separating the oil outlet channel 400 into the first oil outlet channel 420 and the second oil outlet channel 440.

[0045] See also Figures 8 to 10 In one embodiment of the present invention, the first baffle plate 310 and the second baffle plate 410 are respectively disposed in the two second recesses 820 of one of the second plates 800 to seal the through-holes 730 in the second recess 820. The first protrusion 710 and the second recess 820 cooperate to form the oil inlet channel 300 and the oil outlet channel 400. By sealing the through-holes 730 in the second recess 820, the oil inlet channel 300 and the oil outlet channel 400 are also separated. Furthermore, two first baffle plates 310 are provided, one sealing the through-hole 730 of the first protrusion 710 and the other sealing the through-hole 730 of the second recess 820 abutting the first protrusion 710, thereby reducing the risk of lubricating oil in the first and second oil inlet channels 320 and 330 leaking between the first protrusion 710 and the second recess 820 abutting the first protrusion 710. Similarly, two second blocking plates 410 are provided, which respectively close the through hole 730 of another first protrusion 710 on the first plate 700 where the first blocking plate 310 is located and the through hole 730 of the second recess 820 abutting against the first protrusion 710 .

[0046] In one embodiment of the present invention, the oil inlet channel 300 and the oil outlet channel 400 are both perpendicular to the oil flow channel 100, enabling parallel connection between multiple layers of the oil flow channel 100 and improving the uniformity of lubricating oil flow within the multiple layers of the oil flow channel 100. The water inlet channel 910 and the water outlet channel 920 are both perpendicular to the water flow channel 200, enabling parallel connection between multiple layers of the water flow channel 200 and improving the uniformity of lubricating water flow within the multiple layers of the water flow channel 200.

[0047] The second aspect of the present invention provides a vehicle including any of the above-described oil coolers, wherein a single oil cooler cools two oil circuits. For example, if the vehicle is a hybrid vehicle, it may include both a motor and a transmission. The motor and transmission are cooled and lubricated via a first oil channel and a second oil channel, respectively. The vehicle of the present invention also includes a powertrain, a control mechanism, a vehicle body, and other components. Please refer to existing vehicles for details, and this application will not elaborate on these components.

[0048] The oil cooler of this utility model cools two oil circuits through a single water circuit, which reduces the layout of the oil cooler, facilitates the design and utilization of the vehicle space, and reduces the need for water pumps, thus reducing costs. Therefore, this utility model effectively overcomes some practical problems of the existing technology and has high utilization value and practical significance.
