Description

Technical Field

[0001] This utility model relates to the technical field of lubricating oil cooling devices, specifically a lubricating oil cooler with an internal circulation system. Background Technology

[0002] The function of an oil cooler is to cool the lubricating oil and maintain its temperature within the normal operating range. High-powered, high-performance engines, due to their large heat load, must be equipped with oil coolers. When the engine is running, the viscosity of the engine oil decreases as the temperature rises, reducing its lubricating capacity. Therefore, some engines are equipped with oil coolers, whose function is to lower the oil temperature and maintain a certain viscosity of the lubricating oil.

[0003] A search revealed that a typical cooling device in the prior art is disclosed in CN216520871U, which describes a generator set lubricating oil cooling device. This device includes a lubricating oil pipe and a cooling system for cooling the lubricating oil pipe. The lubricating oil pipe is circulated and connected to the generator set. The cooling system includes a water tank and a cooling pipe circulated and connected to the water tank. The cooling pipe has a heat exchange section. A circulating water pump is installed at the inlet end of the cooling pipe. The lubricating oil pipe passes through the heat exchange section. First guide grooves are evenly distributed on the lubricating oil pipe. Heat dissipation fins are evenly distributed on the side wall of the water tank, and a first cooling fan is installed above the water tank to cool the heat dissipation fins. By passing the lubricating oil pipe through the heat exchange section of the cooling pipe, the coolant comes into contact with the lubricating oil pipe as it passes through the heat exchange section and increases its flow velocity along the first guide groove, thus completing the heat exchange of the lubricating oil pipe. After the coolant returns to the water tank, it is cooled by the first cooling fan above it, preventing problems such as component wear, power reduction, or even shutdown of the generator set, and ensuring the effective operation of the generator set.

[0004] In summary, existing lubricating oil cooling devices use water cooling to reduce temperature during use. However, water cooling is slow and uneven, which affects cooling efficiency. To address these issues, existing equipment needs to be improved. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a lubricating oil cooler with an internal circulation system, according to... Figure 1 , Figure 2 and Figure 3 As shown, an oil inlet 201 is provided in the middle of the upper end of the oil storage tank 2, and partition plates 202 are symmetrically arranged on both sides inside the oil storage tank 2. At the same time, a conveying pipe 203 is arranged in the middle of the partition plates 202 at the upper end of the oil storage tank 2, and an oil pump 204 is arranged in the middle of the conveying pipe 203. The oil pump 204 facilitates the segmented cooling and delivery of lubricating oil in adjacent cavities. Two temperature detectors 205 are arranged on the front of the oil storage tank 2, and the two temperature detectors 205 are respectively located on one side of the middle cavity and one of the side cavities inside the oil storage tank 2. The temperature detectors 205 are existing technology, and the temperature detectors 205 facilitate the monitoring of the lubricating oil stored in the inner cavity of the oil storage tank 2. The temperature of the lubricating oil is monitored. The lower end of the oil reservoir 2 is connected to the engine body 1 via a pipe, and a cooling oil pipe 3 is installed on one side of the engine body 1. The middle of the cooling oil pipe 3 is located inside the cooling box 4. An oil pump 301 is installed on the cooling oil pipe 3, and the middle of the cooling oil pipe 3 has an S-shaped structure to improve the heat dissipation effect. The other end of the cooling oil pipe 3 passes through the cooling box 4 and is connected to one side of the second filter box 6. The other side of the second filter box 6 is connected to one side of the oil reservoir 2 via a return pipe 5. At the same time, the back of the oil reservoir 2 and the front of the cooling box 4 are connected by multiple heat exchange plates 7. The heat exchange plates 7 further improve the heat exchange effect, so that the lubricating oil is cooled quickly.

[0022] In use, the lubricating oil containing heat from inside the engine body 1 is pumped through the oil pump 301 into the coolant stored in the cooling tank 4 via the cooling oil pipe 3. The heat is exchanged and cooled by the coolant. After cooling, the lubricating oil is filtered through the second filter box 6 and then enters one side cavity inside the oil reservoir 2 through the return pipe 5. The lubricating oil in this cavity is then transported to the middle cavity through the delivery pipe 203 by the oil pump 204 for cooling again until the lubricating oil temperature drops to the lowest point. Then, the lubricating oil in this cavity is transported to the other side cavity through the delivery pipe 203 by the oil pump 204 and enters the engine body 1 again for reuse.

[0023] according to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, multiple first stirring components 8 are equidistantly arranged below the middle of the heat dissipation oil pipe 3 inside the cooling tank 4. One end of the first stirring component 8 in the middle passes through the cooling tank 4 and the oil storage tank 2 and is connected to the second stirring component 9 in the middle of the oil storage tank 2. At the same time, the other ends of the multiple first stirring components 8 pass through the cooling tank 4 and are connected to the drive motor 11 through the transmission component 10. The transmission component 10 includes a drive gear, a transmission gear, and a rotating gear. The drive gear is connected to the output end of the drive motor 11 and one end of the first stirring component 8 in the middle through a coupling. At the same time, three transmission gears are meshed on the outer side of the drive gear, and the outer ends of the three transmission gears are respectively meshed with rotating gears. The rotating gear is connected to one end of the first stirring component 8 on both sides, and the rotating gear at the upper end is connected to the drive shaft. The drive shaft is connected to the cooling fan 12 in the middle. Through the transmission component 10, the coolant and lubricating oil are cooled synchronously. The cooling fan 12 is installed at the middle rear side of the upper end of the cooling box 4. At the same time, multiple heat dissipation fins 13 are equidistantly arranged at the upper end of the cooling box 4 in front of the cooling fan 12. Through the heat dissipation fins 13, the heat in the steam generated inside the cooling box 4 is exchanged, and the steam condenses into water droplets and falls down, thereby avoiding excessive coolant consumption and improving the heat dissipation and cooling effect.

[0024] To further explain, a liquid inlet 401 and a liquid level detector 402 are provided on one side of the upper end of the cooling tank 4. The liquid level detector 402 facilitates the detection of the liquid level in the cooling tank 4, preventing the liquid level from falling below the height of the middle position of the heat dissipation oil pipe 3. The bottom of the cooling tank 4 is inclined. At the same time, one side of the lower end of the cooling tank 4 is connected to the upper end of the side of the cooling tank 4 near the liquid inlet 401 through a circulation pipe 403. A first filter box 404 is provided in the middle of the circulation pipe 403, and a circulation pump 405 is installed on the side of the circulation pipe 403 near the liquid inlet 401. The circulation pump 405 filters the coolant in the cooling tank 4 through the first filter box 404 and then re-enters the cooling tank 4 through the circulation pipe 403 for reuse.

[0025] In use, the drive motor 11 drives the transmission assembly 10 to rotate, which in turn drives the first stirring assembly 8, the second stirring assembly 9 and the cooling fan 12 to rotate synchronously. This allows the first stirring assembly 8, the second stirring assembly 9 and the cooling fan 12 to cool the coolant inside the cooling tank 4, the lubricating oil inside the oil tank 2 and the cooling fins 13, respectively, thus improving the practicality of the device.
