[0035] Please refer to Figure 1-7 , this utility model provides a technical solution:

[0036] For the embodiment, please refer to Figure 1 、 2 、3, 4, 5, 6 and 7, a new type of environmentally friendly oil filter and cooling module assembly, including a base body 1. One end of the base body 1 is provided with an oil inlet and outlet docking end 3 for docking an oil pump and an engine. An oil passage structure is arranged inside the base body 1, and the oil passage structure includes an oil inlet chamber, an oil outlet chamber, an oil drain chamber and an oil inlet passage when blocked; a cooler 2 is arranged at the upper end of the base body 1, and the cooler 2 is cooperatively docked with the oil inlet and outlet docking end 3 for cooling the oil entering therein. The cooler 2 is cooperatively docked with the oil inlet chamber to convey the cooled oil; a filter assembly is arranged at the other end of the base body 1, and the filter assembly is communicated with the oil passage structure inside the base body 1 to filter the oil entering therein and convey it to the oil inlet and outlet docking end 3 through the oil outlet chamber.

[0037] The oil filter and cooling module assembly is docked with the oil pump and the engine through the oil inlet and outlet docking end 3. The oil pump inputs the oil through the oil inlet and outlet docking end 3 into the base body 1 and enters the cooler 2 for cooling the oil. The cooled oil enters the filter assembly through the oil inlet chamber to filter the impurities in the oil, and the cooled inlet oil re-enters the engine through the oil outlet chamber and the oil inlet and outlet docking end 3 to lubricate the internal structure of the engine;

[0038] The oil circuit structure is also provided with an oil inlet passage when blocked. When the cooler 2 is blocked, the internal pressure increases, and the lubricating oil directly enters the interior of the filter assembly through the oil inlet passage when blocked for filtration. When the pressure difference is higher than the valve opening pressure, the cooler bypass valve b14 opens, and the engine oil directly enters the filter assembly for filtration;

[0039] When the filter assembly needs to be replaced, open the filter assembly, and release the lubricating oil in the filter assembly through the oil drain passage.

[0040] Please refer to Figure 1 、 2 and 3, the filter assembly includes a filter element seat 4 fixedly connected to the end of the base body 1, and a filter cartridge 5 is rotatably connected to the end of the filter element seat 4; a central tube 7 is arranged inside the filter element seat 4, a bypass valve a is installed at the end of the central tube 7, and a filter paper 6 is sleeved outside the central tube 7.

[0041] The filter cartridge 5 rotates in cooperation with the filter element seat 4, and can be conveniently opened for easy replacement and disassembly. With the setting of the bypass valve a, when the filter paper 6 is blocked and the internal pressure increases, the bypass valve a opens, and the lubricating oil directly enters the interior of the central tube 7 through the bypass valve a and is discharged. The lubricating oil enters the oil outlet passage directly without passing through filtration to supply lubrication urgently.

[0042] Please refer to Figure 1 、 2 and 3, the oil inlet passage includes an oil inlet channel. One end of the oil inlet channel is a base oil inlet 8 opened at the upper end of the base body 1, and the other end of the oil inlet channel is a base side oil outlet hole 19 opened inside the filter element seat 4; the oil outlet passage includes an oil outlet channel 10. One end of the oil outlet channel 10 penetrates through the filter element seat 4 and communicates with the interior of the filter element seat 4, and the other end of the oil outlet channel 10 is in butt joint with the oil inlet and outlet docking end 3; the oil drain passage includes an oil drain channel 16 opened inside the base body 1. One end of the oil drain channel 16 penetrates through the filter element seat 4 and communicates with the interior of the filter element seat 4, and the other end of the filter element seat 4 is in butt joint with the oil inlet and outlet docking end 3; the oil inlet passage when blocked includes a direct connection oil inlet channel 12 opened inside the base body 1. One end of the direct connection oil inlet channel 12 penetrates through the filter element seat 4 and communicates with the interior of the filter element seat 4, and the other end of the direct connection oil inlet channel 12 is in butt joint with the oil inlet and outlet docking end 3. A bypass valve b14 is installed inside the direct connection oil inlet channel 12, and an oil drain valve 15 is installed inside the oil drain channel 16.

[0043] When the filter assembly needs to be replaced, use a wrench to loosen the filter cartridge 5. As the filter cartridge 5 rotates and loosens, the valve stem of the oil drain valve 15 pressed by the central tube 7 slowly pops up, and the oil drain valve 15 opens. At this time, the engine oil in the cavity of the filter element seat 4 will flow out to the oil return hole 17 on the mounting surface. This hole is connected to the oil pan and directly returns, avoiding the overflow of the engine oil in the cavity of the filter element seat 4 to the outside and causing environmental pollution.

[0044] The oil inlet and outlet docking end 3 is respectively provided with an oil return hole 17, a base lower oil outlet hole 11 and a base lower oil inlet hole 13. One end of the base lower oil inlet hole 13 is communicated with the base upper oil outlet hole 9 at the upper end of the base main body 1 and one end of the direct connection oil inlet channel 12. The oil return hole 17 is communicated with one end of the oil discharge channel 16. The base lower oil outlet hole 11 is communicated with one end of the oil outlet channel 10. The lower end of the cooler 2 is respectively provided with a cooler oil inlet hole 18 and a cooler oil outlet hole 20. The cooler oil outlet hole 20 is in mating connection with the base oil inlet 8. The cooler oil outlet hole 20 and the cooler oil inlet hole 18 are in mating connection with the base upper oil outlet hole 9.

[0045] In the engine lubrication system, engine oil enters the base lower oil inlet hole 13 on the oil inlet and outlet docking end 3. A one-way check valve is arranged in the base lower oil inlet hole 13. After passing through the one-way check valve, the engine oil enters the cooler 2. The performance requirements of the cooler 2 are as follows: oil flow rate 41.89 L / min, oil temperature 140 °C, coolant (50% water + 50% ethylene glycol) flow rate 29.3 L / min, water temperature 100 °C; heat dissipation greater than 17.5 KW, water side pressure drop less than 40 kPa, oil side pressure drop less than 85 kPa;

[0046] After the engine oil is cooled by the cooler 2, it enters the inside of the filter element seat 4 through the cooler oil outlet hole 20 and the base oil inlet 8 on the base main body 1. The filtration efficiency and dust holding capacity indexes of the engine oil filter are: filtration efficiency: >10 μm, ≥30%; >20 μm, 90%; >30 μm: ≥95%; dust holding capacity: ≥12 g. Engine oil flow rate 20 L / min, termination pressure difference 200 kPa. After being filtered, the engine oil flows to the base lower oil outlet hole 11 through the oil outlet channel 10;

[0047] The engine oil in the engine lubrication system first enters the cooler 2 through the one-way check valve for cooling (if the cooler 2 is blocked and the pressure difference is higher than the valve opening pressure, the bypass valve b14 will open and the engine oil will directly enter the filter element seat 4 for filtration). Then, the filtered engine oil (if the filter paper is blocked and the pressure difference exceeds its opening pressure, the filter element bypass valve a will open and the engine oil will directly enter the oil outlet channel 10 without passing through the filter).

[0048] A positioning convex seat is arranged on one side of the base upper oil outlet hole 9. The lower end of the cooler 2 is provided with a concave part that is in mating connection with the positioning convex seat to ensure the stability of the cooler 2 during installation.

[0049] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
