Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle technology, and in particular to an oil cooling structure and a vehicle. Background Technology
[0002] The function of an oil cooler is to lower the operating temperature of engine oil by using coolant, so that the oil temperature is close to the ideal value.
[0003] Damage to the oil cooler can have a series of consequences. A breach in the internal seal of the oil cooler can lead to oil leakage. The leaking coolant mixes with the oil, causing dilution and emulsification, resulting in poor lubrication. This, in turn, can lead to wear and tear on components, potentially causing engine seizure or bearing failure.
[0004] Secondly, a damaged oil cooler can also affect the engine's cooling system. As oil enters the coolant, the engine's heat dissipation will be severely impaired, potentially leading to overheating. If not addressed promptly, this can cause irreversible damage to the engine.
[0005] In reality, due to the limitations of the vehicle's boundaries and the shallow basin structure of the oil pan, with the oil collector 48mm from the liquid surface, when the vehicle is at an altitude greater than 4000m, the saturated vapor pressure decreases by about 40% when the oil temperature exceeds 135℃. This leads to an increase in oil bubbles, which are drawn in and rupture at the oil cooler, causing cavitation and resulting in internal leakage through the oil cooler. Utility Model Content
[0006] The present invention aims to at least solve the technical problem of increased oil bubbles precipitation in the prior art, which leads to cavitation and internal leakage of the oil cooler after entering the oil cooler.
[0007] Therefore, one objective of this utility model is to provide an oil cooling structure, including an oil inlet collector, wherein the oil inlet of the oil collector is provided with a guide shroud, and the guide shroud is provided with a guide groove.
[0008] Furthermore, the guide shield is arranged around the oil inlet, and the diameter of the guide shield gradually decreases along the oil inlet direction.
[0009] Furthermore, the flow guide groove is a notch opened from the outer end of the flow guide cover inward.
[0010] Furthermore, the oil collector is installed inside the oil pan, and an oil baffle is installed above the oil collector, with the oil baffle positioned above the oil level inside the oil pan.
[0011] Furthermore, the oil baffle has a curved buffer portion along its length edge.
[0012] Furthermore, the oil baffle is provided with an oil return port, which is located on one side of the oil baffle near the edge.
[0013] Furthermore, the oil baffle plate is provided with protruding ribs.
[0014] Furthermore, the oil inlet is a conical structure protruding outwards from the oil collector.
[0015] Furthermore, the bottom of the oil pan is provided with multiple ribs.
[0016] This utility model provides a vehicle including the oil cooling structure described in any of the above claims.
[0017] The oil cooling structure and vehicle provided by this utility model have the following beneficial effects:
[0018] This invention provides a flow guide shroud outside the oil inlet of the oil collector. The upper part of the flow guide shroud is connected to the oil collector. A flow guide groove is provided on the flow guide shroud. While slowing down the oil flow rate, the flow guide groove allows air bubbles to collide with the side wall of the flow guide shroud, thus playing a defoaming role. This prevents oil air bubbles from entering the oil cooler and causing cavitation and internal leakage of the oil cooler.
[0019] The oil inlet has a conical structure, which can buffer the flow rate of the oil, prolong the defoaming time, and reduce the number of air bubbles entering the oil collector. Specifically, the diameter of the guide shield gradually decreases along the oil inlet direction, which can increase the area of action on oil bubbles and improve the defoaming effect.
[0020] An oil baffle is provided above the oil collector, and the edge of the oil baffle has a curved buffer section, which can extend the path of the oil from the engine to the oil return port, thereby extending the defoaming time.
[0021] The oil return port is located at one end of the oil baffle, which extends the oil flow path and prolongs the defoaming time. There is only one oil return port, allowing oil droplets from the engine to converge and enter the oil pan, preventing excessive air bubbles from forming during the oil return process. In contrast, existing technologies have multiple drain holes on the oil baffle, causing oil droplets from the engine to fall through these holes onto the oil pan, generating more air bubbles and increasing the likelihood of cavitation in the oil cooler. This invention reduces the number of hole processing steps, saves processing costs, and increases production cycle time compared to existing technologies. Attached Figure Description

[0045] The following explains the technical terms used in this utility model:
[0046] Oil filter: An oil filter is a device used to filter impurities from engine oil. Its main function is to adsorb metal shavings and other impurity particles to prevent engine wear. The oil filter is installed in the engine's oil pan. Its internal filter screen filters the oil entering the oil pump, ensuring the oil's cleanliness. The oil treated by the oil filter then enters the oil cooler for cooling. The oil filter is connected to the oil cooler through internal engine oil passages; this connection is existing technology and will not be detailed here.
[0047] Oil baffles: Oil baffles are a key component of the internal combustion engine lubrication system. By controlling oil flow and reducing foaming and splashing, they improve engine efficiency and lifespan. Their design must consider engine configuration and oil characteristics, and different types of oil baffles are suitable for different application scenarios. Oil baffles play a vital role in optimizing engine performance and represent technological advancements.
[0048] Oil pan: Located at the bottom of the engine, the oil pan is removable and seals the crankcase, serving as the outer shell for the oil reservoir. Oil pans are typically made of stamped thin steel sheets, while more complex shapes are usually cast from cast iron or aluminum alloy. Internally, it contains a baffle plate to prevent oil splashing caused by engine vibrations and to facilitate the settling of impurities in the lubricating oil. A dipstick is mounted on the side for checking the oil level. Additionally, a drain plug is located at the bottom of the oil pan.
[0049] Example 1
[0050] like Figure 1 and Figure 2 As shown, this embodiment provides an oil cooling structure, including an oil collector 100;
[0051] The oil inlet 1011 of the oil collector 100 is connected to the interior of the oil pan 300. After the oil collector 100 draws in the oil from the oil pan 300, it pumps the oil into the oil cooler through the oil pump.
[0052] The oil inlet 1011 of the oil collector 100 is provided with a flow guide 102. The upper part of the flow guide 102 is connected to the oil collector 100. The flow guide 102 is provided with a flow guide groove 1021. The flow guide groove 1021 is a notch opened from the outer end of the flow guide 102 inward. While slowing down the oil flow rate, the flow guide groove 1021 can cause air bubbles to collide with the side wall of the flow guide 102, thereby playing a defoaming role and preventing oil bubbles from entering the oil cooler and causing cavitation and internal leakage of the oil cooler.
[0053] Example 2
[0054] like Figure 1 and Figure 2 As shown, this embodiment provides an oil cooling structure, including an oil collector 100;
[0055] The oil inlet 1011 of the oil collector 100 is connected to the interior of the oil pan 300. After the oil collector 100 draws in the oil from the oil pan 300, it pumps the oil into the oil cooler through the oil pump.
[0056] The oil inlet 1011 of the oil collector 100 is provided with a flow guide 102. The upper part of the flow guide 102 is connected to the oil collector 100. The flow guide 102 is provided with a flow guide groove 1021. The flow guide groove 1021 is a notch opened from the outer end of the flow guide 102 inward. While slowing down the oil flow rate, the flow guide groove 1021 can cause air bubbles to collide with the side wall of the flow guide 102, thereby playing a defoaming role and preventing oil bubbles from entering the oil cooler and causing cavitation and internal leakage of the oil cooler.
[0057] The difference between this embodiment and the first embodiment is that:
[0058] like Figure 3 As shown, the oil collector 100 includes a collector body 101, and the oil inlet 1011 is disposed on the collector body 101;
[0059] Specifically, the oil inlet 1011 is a conical structure protruding outward from the oil collector 100. This structural design can buffer the flow rate of the oil and reduce the amount of air bubbles entering the oil collector 100.
[0060] Specifically, the radial dimension of the flow guide 102 increases in the direction away from the collector body 101, which increases the area of action on oil bubbles and improves the defoaming effect.
[0061] like Figure 4 As shown, the guide groove 1021 can be any shape, such as semi-circular, square, or circular.
[0062] Example 3
[0063] like Figure 1 and Figure 2 As shown, this embodiment provides an oil cooling structure, including an oil collector 100;
[0064] The oil inlet 1011 of the oil collector 100 is connected to the interior of the oil pan 300. After the oil collector 100 draws in the oil from the oil pan 300, it pumps the oil into the oil cooler through the oil pump.
[0065] The oil inlet 1011 of the oil collector 100 is provided with a flow guide 102. The upper part of the flow guide 102 is connected to the oil collector 100. The flow guide 102 is provided with a flow guide groove 1021. The flow guide groove 1021 is a notch opened from the outer end of the flow guide 102 inward. While slowing down the oil flow rate, the flow guide groove 1021 can cause air bubbles to collide with the side wall of the flow guide 102, thereby playing a defoaming role and preventing oil bubbles from entering the oil cooler and causing cavitation and internal leakage of the oil cooler.
[0066] like Figure 3 As shown, the oil collector 100 includes a collector body 101, and the oil inlet 1011 is disposed on the collector body 101;
[0067] Specifically, the oil inlet 1011 is a conical structure protruding outward from the oil collector 100. This structural design can buffer the flow rate of the oil and reduce the amount of air bubbles entering the oil collector 100.
[0068] Specifically, the radial dimension of the flow guide 102 increases in the direction away from the collector body 101, which increases the area of action on oil bubbles and improves the defoaming effect.
[0069] like Figure 4 As shown, the guide groove 1021 can be any shape, such as semi-circular, square, or circular.
[0070] The present invention differs from the second embodiment in that:
[0071] like Figure 5 As shown, an oil baffle 200 is provided above the oil collector 100. The edge of the oil baffle 200 is attached to the edge of the oil pan 300. This can prevent the oil coming out of the engine from flowing into the oil pan 300 through the gap between the oil baffle and the oil pan 300, so that the oil coming out of the engine can only enter the oil pan 300 through the oil return port 201 provided on the oil baffle 200.
[0072] The oil baffle 200 has a curved buffer section along its length edge, which can extend the path of the oil from the engine to the return port, thereby extending the defoaming time.
[0073] The oil return port 201 is located at one end of the oil baffle 200, which can extend the oil flow path and extend the defoaming time.
[0074] The number of oil return ports 201 is one. Oil droplets dripping from the engine gather together and enter the oil pan 300 through the oil return port 201, which can avoid the generation of more air bubbles during the oil return process. In the prior art, multiple oil drain holes are provided on the oil baffle plate 200. Oil droplets from the engine fall into the oil pan 300 through the oil drain holes and generate more air bubbles, which can more easily lead to cavitation in the oil cooler. Compared with the prior art, this utility model can reduce the processing steps of the holes, save processing costs, and increase production cycle.
[0075] Example 4
[0076] like Figure 1 and Figure 2 As shown, this embodiment provides an oil cooling structure, including an oil collector 100;
[0077] The oil inlet 1011 of the oil collector 100 is connected to the interior of the oil pan 300. After the oil collector 100 draws in the oil from the oil pan 300, it pumps the oil into the oil cooler through the oil pump.
[0078] The oil inlet 1011 of the oil collector 100 is provided with a flow guide 102. The upper part of the flow guide 102 is connected to the oil collector 100. The flow guide 102 is provided with a flow guide groove 1021. The flow guide groove 1021 is a notch opened from the outer end of the flow guide 102 inward. While slowing down the oil flow rate, the flow guide groove 1021 can cause air bubbles to collide with the side wall of the flow guide 102, thereby playing a defoaming role and preventing oil bubbles from entering the oil cooler and causing cavitation and internal leakage of the oil cooler.
[0079] like Figure 3 As shown, the oil collector 100 includes a collector body 101, and the oil inlet 1011 is disposed on the collector body 101;
[0080] Specifically, the oil inlet 1011 is a conical structure protruding outward from the oil collector 100. This structural design can buffer the flow rate of the oil and reduce the amount of air bubbles entering the oil collector 100.
[0081] Specifically, the radial dimension of the flow guide 102 increases in the direction away from the collector body 101, which increases the area of action on oil bubbles and improves the defoaming effect.
[0082] like Figure 4 As shown, the guide groove 1021 can be any shape, such as semi-circular, square, or circular.
[0083] like Figure 5 As shown, an oil baffle 200 is provided above the oil collector 100. The edge of the oil baffle 200 is attached to the edge of the oil pan 300. This can prevent the oil coming out of the engine from flowing into the oil pan 300 through the gap between the oil baffle and the oil pan 300, so that the oil coming out of the engine can only enter the oil pan 300 through the oil return port 201 provided on the oil baffle 200.
[0084] The oil baffle 200 has a curved buffer section along its length edge, which can extend the path of the oil from the engine to the return port, thereby extending the defoaming time.
[0085] The oil return port 201 is located at one end of the oil baffle 200, which can extend the oil flow path and extend the defoaming time.
[0086] The number of oil return ports 201 is one. Oil droplets dripping from the engine gather together and enter the oil pan 300 through the oil return port 201, which can avoid the generation of more air bubbles during the oil return process. In the prior art, multiple oil drain holes are provided on the oil baffle plate 200. Oil droplets from the engine fall into the oil pan 300 through the oil drain holes and generate more air bubbles, which can more easily lead to cavitation in the oil cooler. Compared with the prior art, this utility model can reduce the processing steps of the holes, save processing costs, and increase production cycle.
[0087] The difference between this embodiment and the third embodiment is that:
[0088] The number of flow guide grooves 102 is multiple, and they are evenly arranged on the flow guide cover 102.
[0089] The oil baffle 200 is provided with a plurality of protruding ribs 202. The protruding ribs 202 can collide with the oil droplets and play a defoaming role. The protruding ribs 202 can also slow down the flow rate of the oil and facilitate the settling of air bubbles.
[0090] like Figure 6 As shown, the oil pan 300 has an internal cavity for containing engine oil. Multiple reinforcing ribs 301 are provided at the bottom of the cavity. These ribs 301 strengthen the oil pan 300 and also provide some defoaming effect.

[0092] Specifically, the connector 400 is provided with multiple reinforcing ribs to enhance its strength; a connection hole is provided at the end of the connector 400 that connects to the oil baffle 200.
