Description

Technical Field

[0001] The invention relates to the technical field of diesel engines, and in particular to a novel built-in integrated oil cooler. Background Art

[0002] The oil cooler is a device used to reduce the temperature of the engine oil. Its principle is to remove the heat from the oil through heat exchange with the coolant, thereby keeping the oil within a suitable temperature range. With the upgrading of emission regulations, the heat load of the engine is getting larger and larger. The traditional small-displacement engine oil cooler is installed on the oil filter and cooled through an external pipeline. Its cooling efficiency is low and can no longer meet the actual use requirements.

[0003] The existing small-displacement engine oil cooler has low cooling efficiency and poor safety and cannot meet the actual application requirements. In addition, most of the existing oil coolers are cooled first and then filtered, which easily leads to impurities inside the engine body entering the oil cooler without being filtered, causing it to fail. Summary of the invention

[0004] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

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

[0006] Therefore, the purpose of the present invention is to provide a new type of built-in integrated oil cooler, which is designed to solve the problem that "the existing small-displacement engine oil cooler has low cooling efficiency and poor safety to meet practical applications, and most of the existing oil coolers are cooled first and then filtered, which easily leads to impurities inside the engine body entering the oil cooler without being filtered, causing it to fail."

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] A new type of built-in integrated oil cooler, including:

[0009] An oil cooler seat, an oil filter canister is fixedly arranged at the bottom of the oil cooler seat, an oil cooler core is arranged on the rear side wall of the oil cooler seat, a first oil passage is arranged on the oil cooler seat, the first oil passage is connected with the oil filter canister, a second oil passage, a third oil passage and a fourth oil passage are respectively arranged on the oil cooler seat, the second oil passage is connected with the third oil passage, the third oil passage is connected with the fourth oil passage, an oil inlet hole and an oil outlet hole are respectively arranged between the third oil passage and the oil cooler core, the oil inlet hole and the oil outlet hole are respectively located on the left and right sides of the fourth oil passage, and a bypass valve device is arranged in the third oil passage.

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

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

[0015] As a preferred solution of the novel built-in integrated oil cooler described in the present invention, a third oil hole is provided at the bottom of the oil cooler seat, and the third oil hole is connected to the fourth oil channel.

[0016] As a preferred solution of the novel built-in integrated oil cooler described in the present invention, a plurality of bolts are arranged on the oil cooler seat, and a sealing gasket is arranged on the rear side wall of the oil cooler seat.

[0017] As a preferred solution of the novel built-in integrated oil cooler described in the present invention, a drain switch bracket, a supercharger oil extraction bracket and an oil pressure sensor bracket are respectively provided on the oil cooler seat.

[0018] Beneficial effects of the present invention:

[0019] 1. The device is fixed to the engine body by nine bolts and sealing gaskets. The oil cooler core is completely immersed in the engine body water jacket. The oil is heat exchanged by the flow of coolant in the water jacket. After being pumped out from the oil pump, the oil first goes to the first oil hole, enters the filter canister housing through the first oil hole, and then is filtered through the filter screen. After being filtered from the filter canister housing, the oil enters the oil cooler core through the oil outlet, the first oil channel, the second oil channel and the third oil channel for cooling. After the oil is cooled, it enters the fourth oil channel from the oil outlet hole and is discharged from the third oil hole. The engine is then lubricated. Through the setting of the oil filter canister, the oil is filtered first and then cooled to ensure the filtration of the oil and its cooling effect.

[0020] 2. When the oil pressure before entering the filter canister housing is too high, the pressure relief valve device opens, allowing part of the oil to leak into the inner cavity of the engine body through the second oil hole, reducing the oil pressure and protecting the engine parts.

[0021] 3. When the pressure loss before and after cooling is greater than the protection value, the bypass valve device opens. At this time, the oil does not undergo cooling and directly enters the fourth oil channel, reducing the pressure loss, increasing the engine oil pressure, and ensuring normal operation of the engine.

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

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

[0035] Among them, the engine filter canister 4 includes a canister housing 4a, a filter screen 4b is movably arranged in the canister housing 4a, a plurality of oil inlets 4d are opened on the canister housing 4a, and an oil outlet 4c is opened in the middle of the top of the canister housing 4a. The engine oil enters the canister housing 4a through the oil inlet 4d, so that the engine oil is filtered through the filter screen 4b, and is discharged through the oil outlet 4c after the filtering is completed.

[0036] Furthermore, a joint 7 is fixedly connected to the filter tank housing 4a, and the joint 7 is communicated with the first oil passage 12. The connection with the first oil passage 12 is ensured by connecting the filter tank housing 4a with the first oil passage 12 through the joint 7.

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

[0038] Furthermore, a sealing ring 6 is provided on the pressure relief valve device 5 . The sealing ring 6 is made of rubber material. The sealing performance of the second oil hole 17 is ensured by the provision of the sealing ring 6 .

[0039] Furthermore, a bypass valve device 3 is provided between the fourth oil channel 15 and the third oil channel 14. The bypass valve device 3 is used to adjust the pressure loss. When the pressure loss before and after cooling is greater than the protection value, the bypass valve device 3 is opened. At this time, the engine oil does not undergo cooling and directly goes to the fourth oil channel 15. This reduces the pressure loss, increases the engine oil pressure, and ensures the normal operation of the engine.

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

[0041] Furthermore, a plurality of bolts 2 are provided on the oil cooler seat 1, 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 engine body.

[0042] Furthermore, the oil cooler seat 1 is provided with a drain switch bracket 9, a supercharger oil extraction bracket 10 and an oil pressure sensor bracket 11, through which the drain switch bracket 9, the supercharger oil extraction bracket 10 and the oil pressure sensor bracket 11 are respectively installed with the peripheral equipment.

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

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

[0045] When the pressure loss before and after cooling is greater than the protection value, the bypass valve device 3 is opened. At this time, the engine oil does not undergo cooling and directly enters the fourth oil passage 15, thereby reducing the pressure loss, increasing the engine oil pressure, and ensuring the normal operation of the engine.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
