Description

Technical Field

[0001] This invention relates to the field of oil cooler technology, and in particular to a high-heat-dissipation oil cooler structure for automobiles. Background Technology

[0002] When an engine is old or the oil and filter haven't been changed for a long time, the oil contains too many metal particles that cannot be completely filtered out by the oil filter. If the oil filter element is not replaced in time, it will affect the oil filtration effect, causing it to become less effective. In such cases, when oil enters the oil cooler, it will carry too many metal particles. This excessive metal particles in the oil necessitate a filtration mechanism in the oil cooler to further filter the oil as it enters the internal pipes, reducing the damage caused by metal debris and other impurities to the internal pipes of the oil cooler.

[0003] In existing technologies, most filter mechanisms adopt traditional perforated filter screen structures. Not only is the filtration accuracy poorly adaptable, but the single pore size can only intercept debris of a fixed size, which cannot meet the filtration needs of impurities of multiple sizes in engine oil. Furthermore, long-term impact and compression of metal debris can easily enlarge and deform the filter screen pores, resulting in a significant decrease in filtration effect over time. At the same time, the difficulty in frequently cleaning and maintaining the cooler interior leads to weak anti-clogging ability. During the accumulation of debris, the filter screen pores can be completely blocked, causing obstruction of engine oil flow and thus affecting engine oil supply pressure and lubrication efficiency.

[0004] Therefore, this application provides a high-heat-dissipation oil cooler structure for automobiles to meet the requirements. Summary of the Invention

[0005] The technical problem this invention aims to solve is to provide a high-heat-dissipation oil cooler structure for automobiles to address the shortcomings of existing perforated filter screen structures. These structures not only have poor filtration accuracy adaptability, but their single pore size can only intercept debris of a fixed size, failing to meet the filtration requirements of impurities of various sizes in the oil. Furthermore, long-term impact and compression from metal debris can easily enlarge and deform the filter screen pores, leading to a significant decrease in filtration efficiency over time. Additionally, the difficulty in frequently cleaning and maintaining the cooler's interior results in weak anti-clogging capabilities, with debris accumulation easily clogging the filter screen channels completely, obstructing oil flow and consequently affecting engine oil supply pressure and lubrication efficiency.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A high-heat-dissipation oil cooler structure for automobiles includes an oil cooler body and an oil inlet opened at the bottom of the oil cooler body. An oil outlet is opened at the bottom of the oil cooler body away from the oil inlet. A sealing mechanism is detachably connected to the bottom of the oil cooler body, and a connecting mechanism is detachably connected inside the sealing mechanism. The connecting mechanism includes an oil passage guide box that is detachably connected inside the sealing mechanism. The oil passage guide box has a filter chamber inside, and an installation port is provided at the bottom of the filter chamber. The filter chamber is equipped with a filter mechanism for filtering engine oil. The filter mechanism includes a filter block that is detachably connected to the installation port. The filter block has several figure-eight filter channels at the end near the engine oil inlet and several main outlet channels at the end near the engine oil outlet. The main outlet channels are connected to the figure-eight filter channels.

[0007] Optionally, a sealing part is provided at the bottom of the oil cooler body. The sealing mechanism includes a connecting sealing block, and a sealing ring is fixedly connected to the top of the connecting sealing block. The sealing ring cooperates with the sealing part to seal the connection between the connecting sealing block and the bottom of the oil cooler body.

[0008] Optionally, a placement groove is provided at the bottom of the connecting sealing block, and two mating holes are provided at the top of the placement groove corresponding to the oil inlet and oil outlet.

[0009] Optionally, the connecting mechanism also includes a front docking inlet located at the bottom of the oil passage guide box corresponding to the oil inlet. A flow guide cavity is provided at one end of the oil passage guide box near the oil cooler body. A connecting cavity is provided between the flow guide cavity and the rear docking inlet. A rear docking inlet is provided at a location on the outer wall of the oil passage guide box corresponding to the oil inlet. The rear docking inlet passes through a docking hole corresponding to the oil inlet and docks with the oil inlet.

[0010] Optionally, the outer wall of the oil passage guide box is provided with a docking outlet at one end corresponding to the oil outlet, and the docking outlet passes through the oil passage guide box.

[0011] Optionally, the inner wall of the figure-eight filter channel is provided with several vertically arranged filter media movement slots, the size of which decreases sequentially from the opening of the figure-eight filter channel towards the main outlet channel.

[0012] Optionally, a secondary channel inlet is provided at the connection between the figure-eight filter channel and the main outlet channel, and a secondary outlet channel is provided between every two main outlet channels for the filter block, with the secondary channel inlet connected to the secondary outlet channel.

[0013] Optionally, the oil circuit guide box is provided with a communication mechanism, which includes a sealing sliding hole opened on the side of the communication cavity away from the filter cavity, a limiting groove opened on the side of the docking outlet away from the sealing sliding hole, a sealing cylinder slidably connected inside the sealing sliding hole, an extension ring fixedly connected to the outer wall of the sealing cylinder, a spring fixedly connected between the extension ring and the inner wall of the communication cavity away from the filter cavity, multiple communication holes opened on the outer wall of the sealing cylinder, a limiting part fixedly connected on the side of the sealing cylinder away from the extension ring, and the limiting part slidably connected to the limiting groove.

[0014] Optionally, the figure-eight filter channel is equipped with an anti-clogging mechanism, which includes a push-pull bar rotatably connected to the extension ring. The end of the push-pull bar away from the extension ring is rotatably connected to an extension hinge. A connecting bar is fixedly connected to the bottom of the extension hinge. The connecting bar is rotatably connected to the inner wall of the connecting cavity. Several lifting push bars are fixedly connected to the side of the connecting bar away from the push-pull bar. Each lifting push bar passes through the main outlet channel and the figure-eight filter channel.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, when the oil passes through the filter mechanism and enters the main outlet channel via several figure-eight filter channels on the filter block, the width of the figure-eight filter channels gradually decreases towards the main outlet channel. This allows for the filtration of metal debris of various sizes. The filtered metal debris is trapped inside the figure-eight filter channels at a point equal to the width of the metal debris. Furthermore, the three-dimensional filtration through the figure-eight filter channels ensures that debris of different widths remains at different positions, while debris of the same size can remain at positions of the same width but different heights within the figure-eight filter channels. The likelihood of finding debris of the same size in the oil is extremely low. All sizes of debris are effectively filtered through the figure-eight filter channels. The metal debris, trapped inside the figure-eight filter channel, is distributed in different locations according to its size, resulting in an irregular distribution of a large number of metal debris within the channel. There are gaps between every two debris fragments, allowing oil to pass through. This method not only increases the space for debris to be collected within the figure-eight filter channel but also prevents complete clogging of the filter after filtering out a large amount of impurities. Replacing the traditional filter screen with this method, it is not only more durable and reusable after maintenance and cleaning, but also avoids the metal debris from enlarging and deforming the pore structure of traditional perforated filters, thus reducing filtration efficiency and significantly improving the oil filtration effect.

[0016] The filter media movement grooves allow oil debris to be directly embedded in the flow channels as it passes through the figure-eight filter, preventing excessive accumulation in the main flow area and increasing the overall capacity of the filter. This debris embedding in the grooves on the side walls of the figure-eight filter creates a debris-free main flow area in the center, allowing oil to flow preferentially through the middle and improving the flow space and filtration efficiency. Furthermore, the movement grooves allow debris already inside the filter to be moved to the next groove by the flowing oil, preventing it from becoming too tightly stuck and difficult to clean. This also prevents debris near the main outlet from entering the main outlet and leaking out with the continuous flow of oil, thus affecting filtration accuracy.

[0017] The secondary inlet and outlet channels improve oil flow efficiency and volume. After flowing through the figure-eight filter channels to the main outlet channel, the oil simultaneously enters the secondary outlet channel through the secondary inlet. This disperses the amount of oil entering the main outlet channel from the figure-eight filter channels, reducing the pressure of the oil spraying out of the main outlet channel and lowering the oil pressure within the figure-eight filter channels. This increases the flow rate and prevents excessive oil pressure within the multiple figure-eight filter channels of the filter chamber and filter block. This also prevents excessive pressure from displacing metal debris trapped in the figure-eight filter channels and filter media movement grooves, thus affecting the filtration effect and preventing damage to the seals inside the filter chamber.

[0027] Example 1, as Figures 1 to 9 As shown, an embodiment of the present invention provides a high-heat-dissipation oil cooler structure for automobiles, including an oil cooler body 1 and an oil inlet 102 opened at the bottom of the oil cooler body 1. An oil outlet 101 is opened at the bottom of the oil cooler body 1 away from the oil inlet 102. A sealing mechanism 2 is detachably connected to the bottom of the oil cooler body 1. A sealing part 103 is opened at the bottom of the oil cooler body 1. The sealing mechanism 2 includes a connecting sealing block 201. A sealing ring 204 is fixedly connected to the top of the connecting sealing block 201. The sealing ring 204 cooperates with the sealing part 103 to seal the connection between the connecting sealing block 201 and the bottom of the oil cooler body 1. A placement groove 202 is opened at the bottom of the connecting sealing block 201. A docking hole 203 is opened at the top of the placement groove 202 at two locations corresponding to the oil inlet 102 and the oil outlet 101. like Figures 3 to 6As shown, a connecting mechanism 3 is detachably connected inside the sealing mechanism 2. The connecting mechanism 3 includes an oil passage guide box 301 detachably connected inside the sealing mechanism 2. A filter chamber 303 is opened inside the oil passage guide box 301. An installation port 302 is opened at the bottom of the filter chamber 303. The filter mechanism 4 is detachably connected to the installation port 302, which makes it easy to remove the filter mechanism 4 from the oil passage guide box 301 for maintenance. The connecting mechanism 3 also includes a front docking inlet 304 located at the bottom of the oil passage guide box 301, corresponding to the oil inlet 102. A guide cavity 305 is provided inside the oil passage guide box 301 near the oil cooler body 1. A connecting cavity 307 is provided between the guide cavity 305 and the rear docking inlet 306. The rear docking inlet 306 is connected to the outer wall of the oil passage guide box 301 at a location corresponding to the oil inlet 102. The rear docking inlet 306 passes through a docking hole 203 corresponding to the oil inlet 102 and docks with it. The outer wall of the guide box 301 is provided with a docking outlet 308 at one end corresponding to the oil outlet 101. The docking outlet 308 passes through the oil passage guide box 301. After the oil enters the filter chamber 303 through the front docking inlet 304, it will be filtered by the filter mechanism 4 and enter the connecting chamber 307. It will be guided by the guide chamber 305 and enter the oil cooler body 1 through the rear docking inlet 306 which passes through the docking hole 203 and docks with the oil inlet 102 for cooling. Then it will flow back into the engine through the docking outlet 308 which docks with the oil outlet 101. like Figure 7 and Figure 9As shown, the filter chamber 303 is equipped with a filter mechanism 4 for filtering engine oil. The filter mechanism 4 includes a filter block 401 detachably connected to the mounting port 302. The filter block 401 has several figure-eight filter channels 402 at one end near the engine oil inlet 102 and several main outlet channels 404 at the other end near the engine oil outlet 101. The main outlet channels 404 are connected to the figure-eight filter channels 402. When the engine oil passes through the filter mechanism 4 and enters the main outlet channels 404 through the several figure-eight filter channels 402 on the filter block 401, the width of the figure-eight filter channels 402 to the main outlet channels 404 gradually decreases, which can filter out metal debris of various sizes. The filtered metal debris will be stuck inside the figure-eight filter channels 402, located in the same position as the metal debris. At a point where the width of the debris is equal, and through the figure-eight filter channel 402 in a three-dimensional filtration manner, debris of different widths will stay in different positions. Debris of the same size can stay in positions of the same width but different heights inside the figure-eight filter channel 402. The situation where there are debris of the same size in the oil is extremely low. Debris of various sizes is filtered through the figure-eight filter channel 402 and stays inside the figure-eight filter channel 402. It will be distributed in different positions according to the size of the debris, so that a large number of metal debris are irregularly distributed inside the figure-eight filter channel 402. There will be gaps between every two pieces of debris for the oil to pass through. In this way, not only is the space for debris to be collected inside the figure-eight filter channel 402 increased, but also the phenomenon of completely clogging the filter part is avoided after filtering out a large number of impurities. The inner wall of the figure-eight filter channel 402 has several vertically arranged filter media movement grooves 403. The size of the filter media movement grooves 403 decreases sequentially from the opening of the figure-eight filter channel 402 towards the main outlet channel 404. Through the filter media movement grooves 403, when the oil passes through the figure-eight filter channel 402, some debris can be directly embedded in the filter media movement grooves 403, avoiding excessive accumulation in the main flow area of ​​the figure-eight filter channel 402. This increases the overall storage capacity of the figure-eight filter channel 402. The filter material movement groove 403 on the side wall of the filter channel 402 can form a main flow area without debris obstruction in the middle of the eight-shaped filter channel 402 when the oil passes through the eight-shaped filter channel 402, so that the oil can flow through the middle first, increasing the oil flow space of the eight-shaped filter channel 402 and further improving the efficiency of oil filtration and flow. In addition, the filter material movement groove 403 can also move the debris that has been placed inside the eight-shaped filter channel 402 to the next filter material movement groove 403 when it is flushed and displaced by the oil flowing inside the eight-shaped filter channel 402. A secondary channel inlet 406 is provided at the connection between the figure-eight filter channel 402 and the main outlet channel 404. A secondary outlet channel 405 is provided between every two main outlet channels 404 of the filter block 401. The secondary channel inlet 406 and the secondary outlet channel 405 are connected. The secondary channel inlet 406 and the secondary outlet channel 405 can improve the flow efficiency of the engine oil and increase the flow volume of the engine oil. After the engine oil flows from the figure-eight filter channel 402 into the main outlet channel 404, it will simultaneously pass through the secondary channel inlet 406 into the secondary outlet channel 405, dispersing the amount of engine oil entering the main outlet channel 404 from the figure-eight filter channel 402, reducing the pressure of the engine oil sprayed out from the main outlet channel 404, reducing the pressure of the engine oil inside the figure-eight filter channel 402, and increasing the flow volume of the engine oil.

[0028] The working principle of the technical solution provided by this invention is as follows: After entering the filter chamber 303 through the front docking inlet 304, the engine oil is filtered by the filter mechanism 4 and enters the connecting chamber 307. It is then guided by the flow guide chamber 305 and enters the oil cooler body 1 through the rear docking inlet 306, which connects to the oil inlet 102 via the docking hole 203, for cooling. It then flows back into the engine through the docking outlet 308, which connects to the oil outlet 101. During filtration by the filter mechanism 4, the engine oil passes through several figure-eight filter channels 402 on the filter block 401 and enters the main outlet channel 404. The width of the figure-eight filter channels 402 gradually decreases towards the main outlet channel 404, filtering out metal debris of various sizes. The filtered metal debris gets trapped inside the figure-eight filter channels 402, located at a distance equal to the width of the metal debris. In a three-dimensional filtration manner through the figure-eight filter channel 402, debris of different widths can be placed in different positions, while debris of the same size can be placed in positions of the same width but different heights inside the figure-eight filter channel 402. The situation where there are debris of the same size in the oil is extremely low. Debris of various sizes is filtered by the figure-eight filter channel 402 and placed inside the figure-eight filter channel 402. It will be distributed in different positions according to the size of the debris, so that a large number of metal debris are irregularly distributed inside the figure-eight filter channel 402. There will be gaps between every two pieces of debris for the oil to pass through. In this way, not only is the space for debris to be collected inside the figure-eight filter channel 402 increased, but also the phenomenon of completely clogging the filter part is avoided after filtering out a large number of impurities. By using the filter media movement groove 403, some debris can be directly embedded in the filter media movement groove 403 when the oil passes through the figure-eight filter channel 402, avoiding excessive accumulation in the main flow area of ​​the figure-eight filter channel 402. This increases the overall storage capacity of the figure-eight filter channel 402. With debris embedded in the filter media movement groove 403 on the side wall of the figure-eight filter channel 402, a debris-free main flow area can be formed in the middle of the figure-eight filter channel 402 when the oil passes through it. This allows the oil to flow preferentially through the middle, increasing the oil flow space of the figure-eight filter channel 402. This design improves the efficiency of oil filtration and circulation. Furthermore, the filter medial movement groove 403 allows debris that has settled inside the figure-eight filter channel 402 to be flushed and displaced by the oil flowing inside the figure-eight filter channel 402. This allows the debris to move to the next filter medial movement groove 403, thus preventing debris from getting too tight on the inner wall of the figure-eight filter channel 402 and making it difficult to clean and maintain. At the same time, it prevents debris from shifting and causing debris near the main outlet channel 404 to enter the main outlet channel 404 and leak out from the main outlet channel 404 as the oil continues to impact it, thus affecting the filtration accuracy. The secondary channel inlet 406 and secondary outlet channel 405 can improve the oil flow efficiency and increase the oil flow volume. After the oil flows from the figure-eight filter channel 402 to the main outlet channel 404, it will simultaneously pass through the secondary channel inlet 406 into the secondary outlet channel 405. This disperses the amount of oil entering the main outlet channel 404 from the figure-eight filter channel 402, reduces the pressure of the oil sprayed out of the main outlet channel 404, reduces the oil pressure inside the figure-eight filter channel 402, and increases the oil flow volume. This prevents excessive oil pressure inside the filter chamber 303 and the multiple figure-eight filter channels 402 of the filter block 401. This avoids excessive pressure from displacing metal debris stuck inside the figure-eight filter channel 402 and the filter material movement groove 403, which would affect the filtration effect, and also avoids damaging the seals inside the filter chamber 303.

[0029] Example 2, as Figure 5 and Figure 8As shown, the oil circuit guide box 301 has a communication mechanism 5 inside. The communication mechanism 5 includes a sealing sliding hole 501 opened on the side of the communication cavity 307 away from the filter cavity 303, and a limiting groove 502 opened on the side of the docking outlet 308 away from the sealing sliding hole 501. A sealing cylinder 503 is slidably connected inside the sealing sliding hole 501. An extension ring 504 is fixedly connected to the outer wall of the sealing cylinder 503. A spring 505 is fixedly connected between the extension ring 504 and the inner wall of the communication cavity 307 away from the filter cavity 303. Multiple communication holes 506 are opened on the outer wall of the sealing cylinder 503. A limiting part 507 is fixedly connected to the side of the sealing cylinder 503 away from the extension ring 504 to limit the movement. The part 507 is slidably connected to the limiting groove 502. When the engine speed is too high and the engine needs a large supply of oil, a large amount of oil will enter the connecting cavity 307, increasing the pressure inside the connecting cavity 307. This will push the sealing cylinder 503 to slide inside the sealing sliding hole 501 and the limiting part 507 to slide inside the limiting groove 502, causing the extension ring 504 to compress the spring 505 and push the connecting hole 506 out of the sealing sliding hole 501 and into the docking outlet 308. This allows the oil to directly enter the docking outlet 308 through the sealing cylinder 503 and the connecting hole 506, mix with the cooled oil, and enter the engine simultaneously. like Figures 6 to 9 As shown, the figure-eight filter channel 402 is equipped with an anti-clogging mechanism 6. The anti-clogging mechanism 6 includes a push-pull strip 601 rotatably connected to the extension ring 504. An extension hinge portion 602 is rotatably connected to the end of the push-pull strip 601 away from the extension ring 504. A connecting strip 603 is fixedly connected to the bottom of the extension hinge portion 602. The connecting strip 603 is rotatably connected to the inner wall of the connecting cavity 307. Several lifting push strips 604 are fixedly connected to the side of the connecting strip 603 away from the push-pull strip 601. Each lifting push strip 604 passes through the main outlet channel 404 and the figure-eight filter channel 402, and is connected via a connecting... When the oil pressure sealing cylinder 503 inside the cavity 307 moves, the extension hinge 602 can be pulled by the push bar 601, causing the lifting push bar 604 to rotate around the connecting bar 603 as the axis, so that the end of the lifting push bar 604 away from the connecting bar 603 is raised. If there are a lot of debris filtered longitudinally at the opening of the figure-eight filter channel 402, the debris at the opening of the figure-eight filter channel 402 can be raised by lifting the end of the lifting push bar 604 away from the connecting bar 603, pushing the debris at the opening to be squeezed upward, thereby increasing the oil inlet space at the opening of the extension hinge 602.

[0030] The working principle of the technical solution provided by this invention is as follows: When the engine speed is too high and the engine requires a large supply of oil, a large amount of oil will enter the connecting cavity 307, increasing the pressure inside the connecting cavity 307. This will push the sealing cylinder 503 to slide inside the sealing slide hole 501 and the limiting part 507 to slide inside the limiting groove 502, causing the extension ring 504 to compress the spring 505 and push the connecting hole 506 out of the sealing slide hole 501 and into the docking outlet 308. This allows the oil to directly enter the docking outlet 308 through the sealing cylinder 503 and the connecting hole 506, mix with the cooled oil, and enter the engine simultaneously. This prevents the oil from being under excessive pressure in the oil cooler body 1, which could cause the cooling channels inside to rupture. At the same time, it can supply oil to the engine in a timely manner, avoiding oil shortage in the engine. When the oil pressure sealing cylinder 503 inside the connecting cavity 307 moves, the extension hinge 602 can be pulled by the push-pull strip 601, causing the lifting push strip 604 to rotate around the connecting strip 603 as an axis. This causes the end of the lifting push strip 604 away from the connecting strip 603 to be lifted up. If there are a lot of debris filtered longitudinally at the opening of the figure-eight filter channel 402, the debris at the opening of the figure-eight filter channel 402 can be lifted up by the lifting push strip 604 at the end away from the connecting strip 603, pushing the debris at the opening to be squeezed upwards, thereby increasing the oil inlet space at the opening of the extension hinge 602 to ensure sufficient oil supply.
