Description

Technical Field

[0001] This invention relates to the technical field of diesel engines, and more particularly to a built-in integrated oil cooler. Background Technology

[0002] An oil cooler is a device used to lower the temperature of engine oil. It works by exchanging heat with the coolant, carrying away heat from the oil and maintaining it within a suitable temperature range. With increasingly stringent emission regulations, engine heat loads are rising. Traditional small-displacement engine oil coolers, mounted on the oil filter and cooled via external piping, have low cooling efficiency and no longer meet practical requirements.

[0003] Existing small-displacement engine oil coolers have low cooling efficiency and poor safety, which do not meet the needs of practical applications. In addition, most existing oil coolers are designed to cool first and then filter, which can easily lead to impurities from inside the engine entering the oil cooler without being filtered, causing it to fail. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] In view of the problems existing in the above-mentioned oil coolers, the present invention is proposed.

[0006] Therefore, the purpose of this invention is to provide a built-in integrated oil cooler, which solves the problems that "existing small displacement engine oil coolers have low cooling efficiency and poor safety, which do not meet the actual application requirements, and most existing oil coolers are designed to cool first and then filter, which can easily lead to impurities inside the engine entering the oil cooler without being filtered, causing it to fail".

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] A built-in integrated oil cooler includes:

[0009] An oil cooler base is provided, with an organic filter canister fixedly installed at the bottom. An oil cooler core is provided on the rear side wall of the oil cooler base. A first oil passage is provided on the oil cooler base, which is connected to the organic filter canister. A second, third, and fourth oil passage are provided on the oil cooler base, which are connected to each other. An oil inlet and an oil outlet are provided between the third oil passage and the oil cooler core, respectively. The oil inlet and the oil outlet are located on the left and right sides of the fourth oil passage, respectively. A bypass valve is provided in the third oil passage.

[0010] As a preferred embodiment of the built-in integrated oil cooler of the present invention, the oil filter tank includes a filter tank shell, a filter screen is movably disposed inside the filter tank shell, a plurality of oil inlets are opened on the filter tank shell, and an oil outlet is opened in the middle of the top of the filter tank shell.

[0011] As a preferred embodiment of the built-in integrated oil cooler of the present invention, a connector is fixedly connected to the filter tank housing, and the connector is connected to the first oil passage.

[0012] As a preferred embodiment of the built-in integrated oil cooler of the present invention, the bottom of the oil cooler base is provided with a first oil hole and a second oil hole, the first oil hole is connected to the oil inlet, and a pressure relief valve is provided between the first oil hole and the second oil hole.

[0013] As a preferred embodiment of the built-in integrated oil cooler of the present invention, the pressure relief valve is provided with a sealing ring, which is made of rubber material.

[0014] As a preferred embodiment of the built-in integrated oil cooler of the present invention, a bypass valve is provided between the fourth oil passage and the third oil passage, and the bypass valve is used to regulate pressure loss.

[0015] As a preferred embodiment of the built-in integrated oil cooler of the present invention, the bottom of the oil cooler base is provided with a third oil hole, which is connected to a fourth oil passage.

[0016] As a preferred embodiment of the built-in integrated oil cooler of the present invention, the oil cooler base is provided with a plurality of bolts, and a sealing gasket is provided on the rear side wall of the oil cooler base.

[0017] As a preferred embodiment of the built-in integrated oil cooler described in this invention, the oil cooler base is respectively provided with a drain switch, a booster oil tap, and an oil pressure sensor.

[0018] The beneficial effects of this invention are:

[0019] 1. This device is fixed to the machine body with nine bolts and sealing washers. The oil cooler core is completely immersed in the water jacket of the machine body. The flow of coolant in the water jacket exchanges heat with the oil. After the oil is pumped out by the oil pump, it first goes to the first oil hole and then enters the filter can housing. It is then filtered through the filter screen. After being filtered in the filter can housing, the oil enters the oil cooler core through the oil outlet, the first oil passage, the second oil passage, and the third oil passage for cooling. After being cooled, the oil enters the fourth oil passage through the oil outlet and then exits through the third oil hole, thus lubricating the engine. Through the setting of the oil filter can, the oil is filtered and then cooled, ensuring the filtration and cooling effect of the oil.

[0020] 2. When the oil pressure before entering the filter housing is too high, the pressure relief valve opens, allowing some oil to leak into the engine cavity through the second oil hole, reducing the oil pressure and protecting engine components.

[0021] 3. When the pressure loss before and after cooling exceeds the protection value, the bypass valve opens. At this time, the oil does not go through cooling and directly enters the fourth oil passage, reducing pressure loss, increasing engine oil pressure, and ensuring normal engine operation.

[0033] Reference Figure 1-5 The present invention provides a built-in integrated oil cooler, comprising:

[0034] An oil cooler base 1 is provided, with an oil filter canister 4 fixedly installed at the bottom. An oil cooler core 8 is provided on the rear side wall of the oil cooler base 1. A first oil passage 12 is provided on the oil cooler base 1, which is connected to the oil filter canister 4. A second oil passage 13, a third oil passage 14, and a fourth oil passage 15 are provided on the oil cooler base 1. The second oil passage 13 and the third oil passage 14 are connected, and the third oil passage 14 and the fourth oil passage 15 are connected. An oil inlet and an oil outlet are provided between the third oil passage 14 and the oil cooler core 8, respectively. The oil inlet and the oil outlet are located on the left and right sides of the fourth oil passage 15, respectively. A bypass valve device 3 is provided in the third oil passage 14.

[0035] The oil filter tank 4 includes a filter tank housing 4a, a filter screen 4b is movably disposed inside the filter tank housing 4a, multiple oil inlets 4d are opened on the filter tank housing 4a, and an oil outlet 4c is opened in the middle of the top of the filter tank housing 4a. The oil enters the filter tank housing 4a through the oil inlets 4d, so that the oil is filtered through the filter screen 4b, and after filtration, it is discharged through the oil outlet 4c.

[0036] Furthermore, a connector 7 is fixedly connected to the filter tank housing 4a. The connector 7 is connected to the first oil passage 12. The connection between the filter tank housing 4a and the first oil passage 12 is ensured through the connection between the connector 7 and the first oil passage 12.

[0037] Furthermore, the bottom of the oil cooler housing 1 is provided with a first oil hole 16 and a second oil hole 17. The first oil hole 16 is connected to the oil inlet 4d. A pressure relief valve 5 is provided between the first oil hole 16 and the second oil hole 17. The oil enters the filter housing 4a through the first oil hole 16 and the oil inlet 4d. The oil is directed into the filter housing 4a. At the same time, if the oil pressure is too high before entering the oil filter housing 4, the pressure relief valve 5 will open to allow some oil to leak from the second oil hole 17 into the engine cavity, thereby reducing the oil pressure and protecting the engine components.

[0038] Furthermore, the pressure relief valve device 5 is equipped with a sealing ring 6, which is made of rubber material. The sealing ring 6 ensures the sealing performance of the second oil hole 17.

[0039] Furthermore, a bypass valve 3 is provided between the fourth oil passage 15 and the third oil passage 14. The bypass valve 3 is used to regulate pressure loss. When the pressure loss before and after cooling exceeds the protection value, the bypass valve 3 is opened. At this time, the oil does not go through cooling and goes directly to the fourth oil passage 15. This reduces pressure loss, increases engine oil pressure, and ensures normal engine operation.

[0040] Furthermore, the bottom of the oil cooler housing 1 is provided with a third oil hole 18, which is connected to the fourth oil passage 15. The cooled oil enters the fourth oil passage 15 through the third oil hole 18 and then enters the engine through the fourth oil passage 15.

[0041] Furthermore, the oil cooler seat 1 is provided with multiple bolts 2, and a sealing gasket is provided on the rear side wall of the oil cooler seat 1 to ensure the sealing between the device and the machine body.

[0042] Furthermore, the oil cooler housing 1 is equipped with a drain switch 9, a turbocharger oil tap 10, and an oil pressure sensor 11, which are respectively connected to external devices.

[0043] During use, the device is fixed to the engine body by nine bolts 2 and sealing washers. The oil cooler core 8 is completely immersed in the engine body's water jacket. The flow of coolant in the water jacket exchanges heat with the engine oil. After being pumped out by the oil pump, the engine oil first goes to the first oil hole 16 and then enters the filter canister housing 4a. It is then filtered through the filter screen 4b. After being filtered in the filter canister housing 4a, the engine oil enters the oil cooler core 8 through the oil outlet 4c, the first oil passage 12, the second oil passage 13, and the third oil passage 14 for cooling. After being cooled, the engine oil enters the fourth oil passage 15 through the oil outlet and is then discharged through the third oil hole 18. It then lubricates the engine. Through the setting of the oil filter canister 4, the engine oil is filtered and then cooled, ensuring the filtration and cooling effect of the engine oil.

[0044] When the oil pressure before entering the filter housing 4a is too high, the pressure relief valve 5 opens, allowing some oil to leak into the engine cavity through the second oil hole 17, reducing the oil pressure and protecting the engine components.

[0045] When the pressure loss before and after cooling exceeds the protection value, the bypass valve 3 opens. At this time, the oil does not go through cooling and directly enters the fourth oil passage 15, reducing pressure loss, increasing engine oil pressure, and ensuring normal engine operation.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
