Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0025] As Figures 1-6As shown, an inner built-in oil radiator, including radiator shell 1, two groups of installation device main body 11 are installed in the middle of the outer side of the radiator shell 1, a plurality of groups of heat conduction sheet 12 are fixedly connected inside the radiator shell 1, first oil pipe 13 is installed outside the heat conduction sheet 12, oil inlet 14 is arranged at one end of the first oil pipe 13, second oil pipe 15 is arranged at one end of the first oil pipe 13 close to the oil inlet 14, the first oil pipe 13 is connected with the oil inlet 14 through the control assembly, oil outlet 16 is opened at one end of the first oil pipe 13 away from the oil inlet 14, when working, first, the heat conduction sheet 12 and the first oil pipe 13 are installed inside the radiator shell 1, then the radiator shell 1 is installed at the working position through the installation device main body 11, then the oil inlet 14 is connected with the outlet of the oil, when the aircraft moves, the sliding starts to heat, the oil needs to be cooled, the control assembly guides the oil into the first oil pipe 13 inside the radiator shell 1, the first oil pipe 13 is in contact with the heat conduction sheet 12, the heat conduction sheet 12 is made of brass and has good heat conductivity, which can take away the heat inside the oil, when the aircraft moves, the airflow generated by the radiator shell 1 will pass through the inside of the heat conduction sheet 12, taking away the heat inside the heat conduction sheet 12, realizing the cooling of the oil, then the oil cooled is introduced into the engine again through the oil outlet 16, when the sliding temperature is low, the control assembly directly guides the oil into the engine through the second oil pipe 15, so that the oil is not cooled, so as to keep the oil temperature within a certain range, the oil plays multiple roles of lubrication, cooling and cleaning in the engine, and its temperature needs to be maintained within a certain range to ensure the efficient and stable operation of the engine, if the oil temperature is too low and the device still cools, it may cause the lubrication effect to decrease and the wear of parts to increase, therefore, through the use of the control assembly, the temperature of the oil is adjusted when the temperature exceeds the temperature range, further reducing the situation that the wear of parts is increased due to the temperature of the oil exceeding the specified range, and the service life of the engine is increased.

[0026] As Figures 2-3As shown in Figure 6, the control component includes a control device housing 2; the control device housing 2 is located on the outside of the radiator housing 1 near the oil inlet 14; the oil inlet 14 and the second oil pipe 15 are connected to the first oil pipe 13 through the control device housing 2; a telescopic rod 23 is installed inside the control device housing 2; a plug 24 is fixedly connected to the telescopic end of the telescopic rod 23; the plug 24 is slidably connected inside the control device housing 2; a temperature and pressure sensing controller body 21 is installed on the outside of the radiator housing 1 near the control device housing 2; a signal line 22 is fixedly connected to the output end of the temperature and pressure sensing controller body 21; a telescopic rod 23 is installed at one end of the signal line 22; during operation, when lubricating oil enters the control device housing... When the lubricating oil is inside the device, the temperature and pressure controller body 21 senses the temperature of the lubricating oil and then drives the telescopic rod 23 to extend and retract via the signal line 22. When the temperature is high, the telescopic rod 23 extends, causing the plug 24 to seal the second oil pipe 15. At this time, the lubricating oil flows into the first oil pipe 13. When the lubricating oil does not need to be cooled, the telescopic rod 23 begins to descend, causing the plug 24 to seal one end of the first oil pipe 13. This increases the flexibility of the device. When using the device, the temperature of the lubricating oil needs to be within a constant range to achieve the best effect. Therefore, by sensing and controlling the movement of the plug 24 through the temperature and pressure controller body 21, the temperature of the lubricating oil can be controlled, further increasing the stability of the device during operation.

[0027] like Figures 1-3 As shown in Figure 6, a servo motor 3 is installed at the end of the signal line 22 away from the telescopic rod 23; the servo motor 3 is located on the outside of the radiator housing 1; a worm gear 31 is fixedly connected to the output end of the servo motor 3; the worm gear 31 is rotatably connected inside the radiator housing 1; a rotating rod 33 is rotatably connected to one side inside the radiator housing 1; a worm wheel 32 is fixedly connected to the end of the rotating rod 33 near the outside of the radiator housing 1; the worm gear 31 is meshed on the outside of the worm wheel 32; a rotating plate 34 is fixedly connected to the outside of the rotating rod 33; during operation, the servo motor 3 is connected to the signal line 22, according to the main body of the temperature and pressure sensing controller. The signal sent by 21 controls the rotation of servo motor 3, which in turn drives worm gear 31 to rotate worm wheel 32. This controls the angle between rotating rod 33 and rotating plate 34 on the outside of radiator housing 1. By controlling the angle of rotating plate 34 on the outside of radiator housing 1, the airflow can be changed when the airflow passes through the heat-conducting fins 12. This improves the heat dissipation effect of the device. Based on the rate of lubricating oil temperature rise monitored by the temperature and pressure controller body 21, the servo motor 3 adjusts the heat dissipation efficiency of the device, keeping the lubricating oil temperature at an optimal value and further increasing the stability of the lubricating oil temperature.

[0028] like Figure 3As shown, a groove 41 is provided on the outer side of the radiator housing 1; multiple sets of support plates 4 are slidably connected inside the groove 41; screws 43 are provided on the outer side of the support plates 4; screws 43 are threadedly connected to the side of the radiator housing 1 near the support plates 4; fan blades 42 are installed inside the support plates 4; during operation, the multiple sets of support plates 4 are installed on one side of the radiator housing 1 by sliding inside the groove 41, and the screws 43 limit the distance between the support plates 4 and the radiator housing 1. When the airflow passes through the support plates 4, it drives the fan blades 42 to start rotating, which can accelerate the flow speed of the airflow inside the radiator housing 1, improve the heat dissipation efficiency of the device, and extend the service life of the equipment.

[0029] like Figures 2-4 As shown, a protective plate 5 is installed on one side of the outer side of the radiator housing 1; multiple sets of vibration blocks 51 are fixed to the outer side of the protective plate 5; when the airflow enters the interior of the radiator housing 1 during operation, a portion of the airflow will pass through the protective plate 5 and directly dissipate heat to the first oil pipe 13. The vibration blocks 51 on the outer side of the protective plate 5 will generate slight vibration when passing through strong winds, which reduces the situation where dust is adsorbed on the outer side of the heat-conducting plate 12 during operation and increases the cleanliness of the heat-conducting plate 12.

[0030] like Figure 1 As shown, a protective shell 6 is fixed to one side of the outer side of the radiator housing 1; the protective shell 6 is installed on the outside of the control device housing 2 to protect the parts inside the control device housing 2, and further increases the service life of the device.

[0031] The working principle is that first, the heat-conducting sheet 12 and the first oil pipe 13 are installed inside the radiator shell 1, then the radiator shell 1 is installed in the working position through the installation device main body 11, and then the oil inlet 14 is connected with the oil outlet. When the aircraft moves, the sliding starts to heat up, and the oil needs to be cooled. The control assembly guides the oil into the first oil pipe 13 inside the radiator shell 1. The first oil pipe 13 is in contact with the heat-conducting sheet 12. The heat-conducting sheet 12 is made of brass and has good heat conductivity, which can take away the heat inside the oil. When the aircraft moves, the airflow generated by the radiator shell 1 will pass through the heat-conducting sheet 12, taking away the heat inside the heat-conducting sheet 12, achieving the cooling of the oil. Then the cooled oil enters the engine through the oil outlet 16. When the sliding temperature is low, the control assembly directly guides the oil into the engine through the second oil pipe 15, so that the oil is not cooled to maintain the oil temperature within a certain range. The oil plays multiple roles in the engine, such as lubrication, cooling, and cleaning. Its temperature needs to be maintained within a certain range to ensure the efficient and stable operation of the engine. If the oil temperature is too low and the device still cools, it may cause the lubrication effect to decrease and the parts to wear out. Therefore, by using the control assembly, the temperature is adjusted when the oil temperature exceeds the temperature range, further reducing the possibility of parts wearing out due to the oil temperature exceeding the specified range, and increasing the service life of the engine. When the oil enters the control device shell 2, the temperature and pressure sensing controller main body 21 senses the temperature of the oil, and then drives the telescopic rod 23 to start telescoping through the signal line 22. When the temperature is high, the telescopic rod 23 is extended, and the plug 24 is closed to the second oil pipe 15. When the oil does not need to be cooled, the telescopic rod 23 starts to descend, and the plug 24 is closed to one end of the first oil pipe 13, increasing the flexibility of the device. When using the device, the temperature of the oil needs to be within a certain range to achieve the best effect. Therefore, by sensing the movement of the plug 24 through the temperature and pressure sensing controller main body 21, the temperature of the oil is controlled, further increasing the stability of the device during operation. The servo motor 3 is connected with the signal line 22, and the servo motor 3 is controlled to rotate according to the signal sent by the temperature and pressure sensing controller main body 21, so that the worm 31 drives the worm gear 32 to rotate, controlling the angle of the rotating rod 33 and the rotating plate 34 outside the radiator shell 1. By controlling the angle of the rotating plate 34 outside the radiator shell 1, the angle of the rotating plate 34 can change the air intake when the airflow passes through the heat-conducting sheet 12, and the cooling effect of the device is adjusted according to the temperature and pressure sensing controller main body 21. The speed of the oil heating is adjusted through the servo motor 3 to adjust the cooling efficiency of the device, so that the temperature of the oil is always maintained at a better temperature value, further increasing the stability of the oil temperature. A plurality of support plates 4 are installed on one side of the radiator shell 1 through sliding in the sliding groove 41.When the airflow passes through the support plate 4, the fan blade 42 is driven to rotate, the flow speed of the airflow in the radiator shell 1 is accelerated, the heat dissipation efficiency of the device is improved, and the service life of the equipment is prolonged; when the airflow passes into the inside of the radiator shell 1, a part of the airflow passes through the protection plate 5 and directly radiates the first oil pipe 13; the vibration block 51 outside the protection plate 5 slightly vibrates when passing through strong wind, the situation that dust is adsorbed to the outside of the heat-conducting sheet 12 in the working process is reduced, and the cleanliness of the heat-conducting sheet 12 is increased; the protection shell 6 is installed outside the control device shell 2 and protects the parts inside the control device shell 2, further increasing the service life of the device.
