Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] Specific implementation method 1: Figure 1-Figure 9 As shown, this embodiment discloses an oil cooler assembly for integrated monitoring of oil pressure and temperature, including a sensor 1, a base plate 2, a bottom chip 3, a top plate 6, a water inlet pipe 7, a water outlet pipe 8, nine chips 5 and ten fins 4, the sensor 1 is mounted on the base plate 2, the bottom chip 3 is welded on the base plate 2, the ten fins 4 and the nine chips 5 are alternately stacked and welded on the base chip 3 from bottom to top, the top plate 6 is welded on the topmost fin 4, the water inlet pipe 7 and the water outlet pipe 8 are welded on the top plate 6, an oil inlet port 9 and an oil outlet port 10 are provided at the lower end of the base plate 2, the sensor 1 is connected to the engine control unit signal, and the sensor 1 is a temperature and pressure integrated sensor.

[0027] Furthermore, the bottom plate 2 is formed by extrusion and has a tapered threaded hole.

[0028] Furthermore, the hollow body inside the top plate 6 is provided with a cooling water path 11 and a cooling oil path 12, the water inlet pipe 7 flows to the water outlet pipe 8 through the cooling water path 11, and the oil inlet 9 flows to the oil outlet 10 through the cooling oil path 12. In the transverse section, there is an acute angle between the length direction of the cooling water path 11 and the length direction of the cooling oil path 12, the cooling oil path 12 corresponds to one diagonal line of the rectangle, and the cooling water path 11 corresponds to the other diagonal line of the rectangle. The cooling water path 11 flows layer by layer from top to bottom, and the cooling oil path 12 flows layer by layer from bottom to top.

[0029] Furthermore, the sensor 1 is connected to the cooling oil circuit 12 through a long groove provided on the bottom surface of the base plate 2 to monitor the pressure and temperature of the cooling oil circuit in real time.

[0030] The bottom plate 2 is formed by extrusion, and a tapered threaded hole is processed. The sensor 1 (the sensor 1 is a combined temperature and pressure sensor, which is a prior art) is tightened according to the specified torque, and the bottom chip 3, the fins 4 and chips 5 alternately stacked from bottom to top, the top plate 6, the water inlet pipe 7, and the water outlet pipe 8 are welded in sequence. The oil cooler is a plate-fin oil cooler, and the cooling water path 11 and the cooling oil path in the oil cooler are cross-shaped; the flow direction is countercurrent, in the oil layer, the oil flows from the oil inlet 9 to the oil outlet 10; in the water layer, it flows from the water inlet pipe 7 to the water outlet pipe 8. The cooling water path 11 and the cooling oil path 12 are hollow cavities inside the top plate 6 of the oil cooler. The cooling water path 11 and the cooling oil path 12 have a certain length. There is an acute angle between the length direction of the cooling water path 11 and the length direction of the cooling oil path 12. The cooling oil path 12 corresponds to one diagonal line of the rectangle, and the cooling water path 11 corresponds to the other diagonal line of the rectangle. The cooling water circuit 11 and the cooling oil circuit 12 of the oil cooler are arranged in a cross-type, which increases the flow length and improves the heat dissipation efficiency of the oil. The sensor 1 is integrated on the bottom plate 2. The sensor 1 is connected to the cooling oil circuit 12 inside the oil cooler to monitor the pressure and temperature of the cooling oil circuit 12 of the oil cooler in real time. The oil enters the oil cooler from the oil inlet 9. After being cooled by the oil cooler, the oil flows out from the oil outlet 10. The sensor 1 monitors the oil pressure and temperature in the cooling oil circuit 12. The integrated sensor 1 is used to monitor the engine oil pressure and temperature in real time to ensure the reliability of the engine operation.

The integrated sensor 1 realizes real-time monitoring of the engine oil pressure and temperature conditions, and transmits the signal to the controller. When the sensor 1 detects that the engine oil temperature is higher than the set value or the engine oil pressure is lower than the set value, the controller receives the signal and sends an alarm signal to ensure the reliable operation of the engine; the engine oil enters the oil cooler from the oil inlet 9, flows out from the oil outlet 10 through the cooling oil circuit 12, the coolant enters the oil cooler from the water inlet 7, and flows out from the water outlet 8 through the cooling water circuit 11. The direction of the cooling oil circuit 12 is arranged in a cross-type with the direction of the cooling water circuit 11, which increases the flow length and can improve the heat dissipation efficiency of the engine oil.

[0032] Integrating sensor 1 on the oil cooler can improve the reliability and accuracy of the oil pressure and temperature monitoring system, prevent the problem of oil viscosity being too low to meet the establishment of lubricating oil film due to excessive oil temperature, help simplify the overall layout, reduce additional pipes and connectors, reduce potential leakage risks, and help reduce weight and optimize space utilization. In short, integrating sensor 1 on the oil cooler is a reasonable design choice that takes into account monitoring accuracy, response speed, compact structure and safety, which is conducive to improving the performance of the whole machine and extending the life of the engine.
