DETAILED DESCRIPTION

[0038] The following describes the details and working principle of the implementation mode and embodiment of the present utility model in conjunction with the accompanying drawings. In the drawings, the X axis is the longitudinal direction, the Y axis is the transverse direction, and the Z axis is the up-down direction.

[0039] A lubricating oil filter radiator assembly includes a lubricating oil filter seat assembly and a radiator 3. The lubricating oil filter seat assembly includes an elongated base 1, that is, the base is long and narrow. The two ends of the base 1 are respectively a first end and a second end. The first end of the base is integrally provided with a filter housing 2, and the filter housing is provided with a lubricating oil inlet 13. The base has an upper surface 11 assembled with the radiator 3 and a lower surface 12 provided with an oil outlet 14. The radiator 3 is assembled on the upper surface 11 of the base. The oil outlet 14 on the lower surface of the base is connected to the oil circuit of the engine. The lubricating oil inlet 13 is also arranged on the lower surface of the base. The base is provided with an oil passage 8, which is arranged longitudinally and connected to the inner cavity of the filter housing 2. The upper surface 11 of the base is provided with a cooling outlet 15 and a cooling inlet 16. The cooling outlet is connected to the oil passage 8, and the cooling inlet is connected to the oil outlet 14. The oil passage 8 is provided with a circuitous section 18, and the flow path 24 of the lubricating oil in the circuitous section is circuitous, which reduces the flow rate of the lubricating oil in this section, so that more lubricating oil enters the radiator 3 from the cooling outlet 15. The circuitous section 18 is preferably arranged between the cooling outlet 15 and the outlet of the oil passage, and the lubricating oil directly enters the radiator 3 from the cooling outlet 15 after being filtered by the filter, without passing through the circuitous section 18, and the flow rate of the lubricating oil entering the radiator will not be reduced. More lubricating oil enters the base from the cooling inlet 16 after being cooled by the radiator, and is output from the oil outlet 14 on the lower surface of the base, so that more of the output lubricating oil has been cooled, which can improve the heat dissipation effect of the lubricating oil as a whole, so that the temperature of the output lubricating oil is relatively lower.

[0040] The tortuous section 18 of the oil passage can be designed to be in the shape of a tortuous curve, so that the flow path 24 of the lubricating oil flowing through this section is tortuous, but it will increase the difficulty of processing the oil passage. Figure 4The tortuous section 18 of the oil passage is substantially a straight channel, and the tortuous section 18 of the oil passage is provided with a baffle 19, which is transversely arranged in the oil passage, and the width of the baffle is narrower than the width of the oil passage or / and the height of the baffle is shorter than the height of the oil passage. By providing the baffle 19, the lubricating oil flow path 24 of the tortuous section is tortuous, so that even if the channel of the tortuous section is a straight channel, the flow path 24 can be changed into tortuous by providing the baffle 19, and the oil passage is a straight channel, which uses more space and is more convenient for processing. The baffles 19 are provided with a plurality of adjacent baffles, for example, the first baffle is connected to the left side wall of the oil passage, but there is a flow gap between it and the right side wall, the second baffle is connected to the right side wall of the oil passage, but there is a flow gap between it and the left side wall of the oil passage, and the third baffle is connected to the left side wall of the oil passage, but there is a flow gap between it and the right side wall. Such a staggered arrangement makes the flow path 24 of the lubricating oil in this section tortuous, thereby reducing the flow rate of the lubricating oil in this section. Or the upper and lower staggered arrangement, that is, the first baffle is connected to the bottom surface of the oil passage, and the second baffle is connected to the top surface of the oil passage, so that the lubricating oil bypasses from top to bottom, forming a tortuous shape. In the attached drawings, one side end of the baffle is installed on one side wall of the oil passage, and the other side end of the baffle has a flow gap with the other side wall of the oil passage. Several baffles are alternately installed on the two side walls of the oil passage, that is, the first embodiment mentioned above.

[0041] The oil passage extends to the first end of the base 1 with a first core opening 6, and the winding section 18 extends to the upper surface 11 of the base with a second core opening 7, and the second core opening 7 is sealed with the bottom surface of the radiator 3. The first core opening 6 and the second core opening 7 are used for core pulling in casting processing, and the core is withdrawn from the first core opening and the second core opening to form an oil passage 8 on the base. The oil outlet 14 on the lower surface 12 of the base is close to the second end of the base 1, and the oil outlet 14 extends upward with an oil hole 21, and the oil hole 21 is connected to the outlet of the oil passage 8; the cooling inlet 16 extends into the base 1 and is connected to the oil hole 21. The radiator 3 is assembled on the upper surface 11 of the base, and the lubricating oil in the oil passage 8 is connected to the radiator 3 through the cooling outlet 15 and the cooling inlet 16. The lubricating oil is discharged from the oil outlet 14 after the heat is dissipated by the radiator 3, thereby reducing the oil temperature as a whole. The bottom surface of the radiator 3 and the upper surface 11 of the base can be connected by screws, and a sealing ring 20 is arranged between the two to ensure the sealing setting. The oil passage is divided into two sections, and two cores are also provided for core pulling during casting processing, which are matched with the first section 17 and the second section of the oil passage 8 respectively. The second section is the tortuous section 18, and the first section 17 is the first end of the tortuous section to the base. The setting of the second core opening 7 greatly reduces the difficulty of processing the oil passage 8, and can process tortuous sections 18 of different shapes; at the same time, the lubricating oil in the oil passage 8 can directly contact the bottom surface of the radiator 3 in the tortuous section 18, further increasing the heat dissipation effect of the lubricating oil. The width of the second core opening 7 is greater than the inlet and outlet of the oil passage 8; the second core opening 7 is laterally expanded near the two side walls of the base, increasing the capacity of the lubricating oil in the tortuous section 18, and also increasing the contact area between the lubricating oil and the radiator 3, and further improving the heat dissipation effect.

[0042] The base 1 is made of metal casting, which has better heat dissipation effect and longer service life. The second end of the base is provided with a mounting port 9, which extends into the base and communicates with the oil hole 21. The mounting port 9 is riveted with a connector 10 with internal threads, which is used to thread the sensor. The mounting port is divided into a pressure sensor mounting port and a temperature sensor mounting port. The pressure sensor 5 and the temperature sensor 4 are threadedly mounted, which makes it easier to maintain the sensor.

[0043] The connector 10 is made of metal casting, and a sealing ring is provided between the connector and the mounting port 9. The metal-cast connector 10 has a long service life and is not easy to age or damage. The connector is riveted into the mounting port, which has a good sealing effect and can be disassembled and replaced. Even if the lubricating oil leaks from the mounting port, it can be repaired by replacing the connector. The mounting port is provided with a protrusion or groove matching the connector 10. The mounting port in the figure is provided with a protrusion 22, and the connector is provided with a matching groove 23. During riveting, the groove 23 of the connector is aligned with the protrusion 22 of the mounting port, and the connector 10 is riveted into the mounting port 9. After riveting, the connector will not rotate circumferentially relative to the mounting port. The base has a core opening due to casting requirements, such as the first core opening 6. These core openings can also be riveted to press metal sealing plugs to seal and block the core openings.

[0044] The working principle of the preferred embodiment is further described below in conjunction with the accompanying drawings: the lubricating oil enters the filter housing 2 from the lubricating oil inlet 13, enters the oil passage 8 after being filtered by the filter, part of the lubricating oil enters the radiator 3 from the cooling outlet 15 through the oil passage, enters the oil hole 21 of the base from the cooling inlet 16 after being cooled by the radiator 3, and finally is discharged from the oil outlet 14; part of the lubricating oil passes through the tortuous section 18 of the oil passage, and due to the obstruction of the baffle, the lubricating oil passes through the flow gap between the baffle and the side wall of the oil passage, and the lubricating oil bypasses multiple baffles in turn, forming a Figure 4 In the tortuous flow path shown, the lubricating oil finally enters the oil hole 21 and is then discharged from the oil outlet 14. Because the lubricating oil is blocked and the flow rate is reduced in the tortuous section, more lubricating oil enters the radiator 3 from the cooling outlet 15, and more lubricating oil is output from the oil outlet 14 after being cooled by the radiator. Compared with the prior art, the proportion of lubricating oil output from the oil outlet that is cooled by the radiator increases, so that the temperature of the output lubricating oil is relatively lower and the heat dissipation effect is better. In addition, the lubricating oil in the tortuous section 1 is in contact with a large area of ​​the bottom surface of the radiator, so that this part of the lubricating oil is cooled and the temperature of the lubricating oil is reduced.
