Description

Technical Field

[0001] This invention relates to the field of engine oil cooling technology, and more particularly to an engine oil cooler and system. Background Art

[0002] During engine operation, engine oil is used for lubrication and cooling. However, when engine oil cools the engine, it absorbs a lot of heat, causing its own temperature to rise. Therefore, in order to extend engine life and improve engine efficiency, it is necessary to cool the engine oil in a timely manner to maintain continuous cooling and heat absorption for the engine.

[0003] In existing technology, oil is introduced into the housing by setting up an oil inlet pipe and an oil outlet pipe. The oil flows in the housing and absorbs heat from the oil by setting up heat-absorbing copper or metal plates inside the housing, thus effectively reducing the temperature.

[0004] In the aforementioned prior art, the heat-absorbing copper fins are typically fixed in position after being placed inside the housing. They come into contact with the oil during flow to exchange heat. Therefore, in order to improve the cooling effect of the oil, a large number of heat-absorbing copper fins are usually required. While this can achieve a good cooling effect when the oil temperature is high, when the oil temperature is low, there is no need for many copper fins for heat exchange. In this case, these copper fins actually obstruct the flow path and reduce the oil flow rate. As a result, the heat-absorbing copper fins cannot be flexibly adjusted according to the oil temperature, which affects the oil flow rate and reduces the oil cooling efficiency and the efficiency of entering the engine for cooling. Summary of the Invention

[0005] The purpose of this invention is to provide an engine oil cooler and system that solves the problem in the prior art where, when the oil temperature is low, there is no need for too many copper plates for heat exchange. At this time, these copper plates actually obstruct the flow path and reduce the oil flow rate. Therefore, the heat-absorbing copper plates cannot be flexibly adjusted according to the oil temperature, which affects the oil flow rate and reduces the oil cooling efficiency and the efficiency of entering the engine for cooling.

[0006] To achieve the above objectives, the present invention provides an engine oil cooler, comprising an oil circulation pipe, two temperature sensors, a cooling box, two flow pipes, a heat absorption block, and an adjustment assembly. The cooling box is fixedly connected to the oil circulation pipe and is sleeved on the outside of the oil circulation pipe. The two temperature sensors are respectively disposed at both ends of the oil circulation pipe, the two flow pipes are respectively disposed at both ends of the cooling box, and the heat absorption block is disposed inside the oil circulation pipe. The adjustment assembly includes a heat-absorbing connecting shaft, a drive shaft, a first rotating drum, a traction rope, and a drive unit. The heat-absorbing connecting shaft is rotatably connected to the oil circulation pipe, and one end of the heat-absorbing connecting shaft passes through the oil circulation pipe. The heat-absorbing block is sleeved on the outer wall of the heat-absorbing connecting shaft. The drive shaft is located at one end of the heat-absorbing connecting shaft and above the cooling box. The first rotating drum is located outside the drive shaft. One end of the traction rope is wound around the outside of the first rotating drum. The drive unit is fixedly connected to the other end of the traction rope.

[0007] The drive unit includes a protective shell, a limiting mechanism, a drive component, a second rotating drum, a rotary mechanism, and a linkage mechanism. The protective shell is located above the cooling box, the drive component is located inside the protective shell, the limiting mechanism is located on the inner top wall of the protective shell, the drive component is located above the cooling box, the output end of the drive component is fixedly connected to the second rotating drum, the rotary mechanism is located on one side of the second rotating drum, and the linkage mechanism is located on the first rotating drum.

[0008] The limiting mechanism includes a telescopic component and a limiting block. The second rotating drum has a limiting groove. The telescopic component is disposed on the inner top wall of the protective shell. The output end of the telescopic component is fixedly connected to the limiting block. The limiting block and the limiting groove are mutually adapted. The other end of the traction rope is fixedly connected to the second rotating drum.

[0009] The rotary mechanism includes a rotary component and a roller. The rotary component is located above the cooling box. The output end of the rotary component is fixedly connected to the roller. The roller is in contact with the outer wall of the second rotating cylinder.

[0010] The linkage mechanism includes a moving block, a fixed block, a spring, a first pressure sensor, a second pressure sensor, and a sensing block. The moving block is disposed on the outer wall of the drive shaft, the fixed block is disposed above the cooling box and located on one side of the drive shaft, the moving block and the fixed block are connected by the spring, the first pressure sensor is disposed on the side of the drive shaft away from the fixed block, the second pressure sensor is disposed on one side of the fixed block, and the sensing block is fixedly connected to the drive shaft and located on the outer wall of the drive shaft.

[0011] The adjustment assembly further includes two first seals, two temperature transmission units, and a second seal. Both ends of the heat-absorbing connecting shaft are located inside the cooling box. The two first seals are respectively sleeved on both ends of the heat-absorbing connecting shaft and located at the rotation point between the heat-absorbing connecting shaft and the oil circulation pipe. The second seal is sleeved on the rotation point between the drive shaft and the cooling box. The temperature transmission unit includes a temperature transmission shaft and multiple temperature transmission rods. The temperature transmission shaft is located inside the cooling box. One end of the temperature transmission shaft is connected to one end of the heat absorption connecting shaft. The multiple temperature transmission rods are sequentially distributed around the outside of the temperature transmission shaft. One end of the drive shaft is fixedly connected to the other end of the corresponding temperature transmission shaft.

[0012] The adjustment assembly further includes multiple reinforcing blocks and multiple cooling baffles. The heat-absorbing block has multiple bending channels, and the reinforcing block has a flow groove. Both ends of the multiple reinforcing blocks are fixedly connected to the heat-absorbing block and the heat-absorbing connecting shaft, respectively. One end of the multiple cooling baffles is fixedly connected to the heat-absorbing connecting shaft, and the other end of the multiple cooling baffles is disposed inside the heat-absorbing block and distributed sequentially between the multiple bending channels.

[0013] The present invention also provides an engine oil cooling system, including the engine oil cooler.

[0014] This invention discloses an engine oil cooler and system. The system is connected to the engine via an oil circulation pipe, allowing the oil to circulate. This circulation pipe is connected to an external cooling medium, which flows within the cooling tank, enveloping the oil circulation pipe. A heat-absorbing connecting shaft and a heat-absorbing block absorb heat from the oil. Simultaneously, the heat-absorbing connecting shaft, positioned within the cooling medium, carries away the absorbed heat, continuously cooling the oil. Two temperature sensors detect the oil temperature before and after cooling. A preset value is set. If the oil temperature after cooling is lower than the preset value, it indicates that the current oil temperature is low, and the entire heat-absorbing block does not need to contact the oil. At this point, the drive unit is activated, driving the first rotating drum to rotate via a traction rope. The rotating shaft and the heat-absorbing connecting shaft cause the heat-absorbing block to rotate 90 degrees, placing it laterally within the heat-absorbing circulation pipe to increase the heat exchange area and thus improve the cooling efficiency of the engine oil. When the temperature is detected to be lower than the preset value, the heat-absorbing block is reset and placed longitudinally within the engine oil circulation pipe, providing greater flow space on both sides of the heat-absorbing block. This increases the fluidity and flow rate of the engine oil, allowing it to enter the engine more quickly and complete a cooling cycle. Through this structural design, when the engine oil temperature is higher than the preset value, the laterally placed heat-absorbing block increases the heat exchange area and improves the cooling effect. When the temperature is lower than the preset value, the longitudinally placed heat-absorbing block increases the oil flow rate and circulation efficiency, thus improving both cooling effect and efficiency, and flexibly adapting to various engine oil cooling conditions.

Detailed Implementation

[0025] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0026] See also Figures 1 to 8This invention provides an engine oil cooler, comprising an oil circulation pipe 1, two temperature sensors 2, a cooling box 3, two flow pipes 4, a heat-absorbing block 5, and an adjustment assembly. The adjustment assembly includes a heat-absorbing connecting shaft 6, a drive shaft 7, a first rotating drum 8, a traction rope 9, and a drive unit. The drive unit includes a protective housing 10, a limiting mechanism, a drive component 11, a second rotating drum 12, a rotary mechanism, and a linkage mechanism. The limiting mechanism includes a telescopic component 13 and a limiting block 14. The second rotating drum 12 has a limiting groove 15. The rotary mechanism includes... The rotating component 16 and the roller 17, the linkage mechanism includes a moving block 18, a fixed block 19, a spring 20, a first pressure sensor 21, a second pressure sensor 22 and a sensing block 23, the adjustment assembly also includes two first seals 24, two temperature transmission units and a second seal 25, the temperature transmission unit includes a temperature transmission shaft 26 and multiple temperature transmission rods 27, the adjustment assembly also includes multiple reinforcing blocks 28 and multiple cooling baffles 29, the heat absorption block 5 has multiple bending channels 30, and the reinforcing block 28 has a flow groove 31.

[0027] The cooling box 3 is fixedly connected to the oil circulation pipe 1 and sleeved on the outside of the oil circulation pipe 1. Two temperature sensors 2 are respectively disposed at both ends of the oil circulation pipe 1. Two flow pipes 4 are respectively disposed at both ends of the cooling box 3. The heat absorption block 5 is disposed inside the oil circulation pipe 1. The heat absorption connecting shaft 6 is rotatably connected to the oil circulation pipe 1. One end of the heat absorption connecting shaft 6 passes through the oil circulation pipe 1. The heat absorption block 5 is sleeved on the outer wall of the heat absorption connecting shaft 6. The drive shaft 7 is disposed at one end of the heat absorption connecting shaft 6 and located above the cooling box 3. The first rotating drum 8 is disposed outside the drive shaft 7. One end of the traction rope 9 is wound around the outside of the first rotating drum 8. The drive unit is fixedly connected to the other end of the traction rope 9. The oil circulation pipe 1 is connected to the engine, allowing the oil to circulate. The flow pipe 4 is connected to an external cooling medium, which flows within the cooling housing 3, enveloping the oil circulation pipe 1. The heat-absorbing connecting shaft 6 and the heat-absorbing block 5 absorb heat from the oil. Simultaneously, the heat-absorbing connecting shaft 6, located within the cooling medium, carries away the absorbed heat, thus continuously cooling the oil. Two temperature sensors 2 detect the oil temperature before and after cooling. A preset value is set; if the oil temperature after cooling is lower than the preset value, it indicates that the current oil temperature is low, and the entire heat-absorbing block 5 does not need to contact the oil. At this time, the drive unit is activated, and the first rotating drum 8 is driven to rotate through the connection of the traction rope 9, causing the drive shaft 7 and the heat-absorbing connecting shaft 6 to rotate, which in turn causes the heat-absorbing block 5 to rotate 90 degrees, increasing the heat exchange area and thus improving the cooling efficiency of the engine oil. When the temperature is detected to be lower than the preset value, the heat-absorbing block 5 is reset and placed longitudinally in the engine oil circulation pipe 1, thereby increasing the flow space of the engine oil and increasing the flow rate of the engine oil, so that the engine oil can enter the engine faster and complete a cooling cycle. The drive shaft 7 is made of heat-insulating material, which can prevent the high temperature inside the cooling box 3 from affecting the normal operation of the drive unit above.

[0028] Secondly, the protective shell 10 is disposed above the cooling box 3, the driving component 11 is disposed inside the protective shell 10, the limiting mechanism is disposed on the inner top wall of the protective shell 10, the driving component 11 is disposed above the cooling box 3, the output end of the driving component 11 is fixedly connected to the second rotating drum 12, the rotary mechanism is disposed on one side of the second rotating drum 12, and the linkage mechanism is disposed on the first rotating drum 8. The protective outer shell 10 protects the internal driving components. When the traction rope 9 drives the first rotating drum 8 to rotate 90 degrees, the limiting mechanism is activated to limit the second rotating drum 12, thereby preventing the traction rope 9 from retracting into the first rotating drum 8 and fixing the drive shaft 7 and the heat-absorbing block 5. The driving component 11 is a motor. When the driving component 11 is activated, it drives the second rotating drum 12 to rotate, causing the traction rope 9 to be wound inside the second rotating drum 12. Then, the traction rope 9 of the first rotating drum 8 is unwound. At the same time, since the traction rope 9 is tightly fitted onto the outer wall of the first rotating drum 8, the first rotating drum 8 rotates. After rotating 90 degrees, the limiting is activated. When it is necessary to reset the heat-absorbing block 5, the limiting is canceled, and then the rotary mechanism is activated to drive the second rotating drum 12 to rotate 90 degrees. At the same time, the linkage mechanism also drives the second rotating drum 12 and the drive shaft 7 to rotate 90 degrees, so that the heat-absorbing block 5 is reset.

[0029] Meanwhile, the second rotating drum 12 has a limiting groove 15, and the telescopic component 13 is disposed on the inner top wall of the protective shell 10. The output end of the telescopic component 13 is fixedly connected to the limiting block 14, and the limiting block 14 and the limiting groove 15 are mutually adapted. The other end of the traction rope 9 is fixedly connected to the second rotating drum 12. The telescopic component 13 is a cylinder. When the telescopic component 13 is activated, it drives the limiting block 14 into the limiting groove 15, thereby limiting and fixing the second rotating drum 12.

[0030] Additionally, the rotary component 16 is positioned above the cooling box 3, and its output end is fixedly connected to the roller 17, which is in contact with the outer wall of the second rotating drum 12. The rotary component 16 is a motor; when activated, it drives the roller 17 to rotate, thereby causing the second rotating drum 12 to rotate.

[0031] Then, the movable block 18 is disposed on the outer wall of the drive shaft 7, the fixed block 19 is disposed above the cooling box 3 and located on one side of the drive shaft 7, the movable block 18 and the fixed block 19 are connected by the spring 20, the first pressure sensor 21 is disposed on the side of the drive shaft 7 away from the fixed block 19, the second pressure sensor 22 is disposed on the side of the fixed block 19, and the sensing block 23 is fixedly connected to the drive shaft 7 and located on the outer wall of the drive shaft 7. When the first rotating drum 8 rotates, it drives the drive shaft 7 to rotate, which in turn drives the moving block 18 closer to the fixed block 19, compressing the spring 20. After rotating 90 degrees, the sensing block 23 comes into contact with the first pressure sensor 21, causing a change in the pressure value of the first pressure sensor 21. This indicates that the heat-absorbing block 5 has rotated 90 degrees and is now in a lateral position, thus limiting the second rotating drum 12. When the heat-absorbing block 5 is reset, the roller 17 rotates, causing the second rotating drum 12 to reset, so that the traction rope 9 is no longer taut. At this time, the compressed spring 20 rebounds, causing the moving block 18 to move away from the fixed block 19, thus resetting the drive shaft 7 and the heat-absorbing block 5. After resetting 90 degrees, the sensing block 23 comes into contact with the second pressure sensor 22 again, causing a change in its pressure value. This indicates that the heat-absorbing block 5 has been reset, and the second rotating drum 12 can be limited again.

[0032] Furthermore, both ends of the heat-absorbing connecting shaft 6 are located inside the cooling box 3. The two first seals 24 are respectively sleeved on both ends of the heat-absorbing connecting shaft 6 and located at the rotation point between the heat-absorbing connecting shaft 6 and the oil circulation pipe 1. The second seal 25 is sleeved on the rotation point between the drive shaft 7 and the cooling box 3. The temperature transmission shaft 26 is located inside the cooling box 3. One end of the temperature transmission shaft 26 is connected to one end of the heat-absorbing connecting shaft 6. A plurality of temperature transmission rods 27 are sequentially distributed around the outside of the temperature transmission shaft 26. One end of the drive shaft 7 is fixedly connected to the other end of the corresponding temperature transmission shaft 26. The first seal 24 and the second seal 25 prevent leakage of engine oil and cooling medium. The temperature transfer unit can transfer the heat of the heat-absorbing connecting shaft 6 to the cooling medium more efficiently, while the heat-absorbing connecting shaft 6 continuously absorbs the temperature of the engine oil, thereby continuously maintaining efficient cooling of the engine oil. The temperature transfer shaft 26 is connected to the heat-absorbing connecting shaft 6, absorbs the heat of the heat-absorbing connecting shaft 6, and then evenly distributes it to the cooling medium through multiple temperature transfer rods 27. The temperature transfer rods 27 are in full contact with the cooling medium, so that the heat-absorbing connecting shaft 6 and the heat-absorbing block 5 are always in a low temperature state and continuously exchange heat with the engine oil.

[0033] Furthermore, the heat-absorbing block 5 has multiple bending channels 30, the reinforcing block 28 has a flow groove 31, both ends of the multiple reinforcing blocks 28 are respectively fixedly connected to the heat-absorbing block 5 and the heat-absorbing connecting shaft 6, one end of the multiple cooling baffles 29 is fixedly connected to the heat-absorbing connecting shaft 6, and the other end of the multiple cooling baffles 29 is disposed inside the heat-absorbing block 5 and is distributed sequentially among the multiple bending channels 30. The reinforcing block 28 strengthens the connection between the heat-absorbing block 5 and the heat-absorbing connecting shaft 6, improving stability. Simultaneously, the heat-absorbing block 5 helps transfer heat from the engine oil to the heat-absorbing connecting shaft 6. The flow groove 31 increases the contact area with the engine oil while maintaining its flowability. The cooling baffle 29 is connected to the heat-absorbing connecting shaft 6, thus better cooling the heat-absorbing block 5. Furthermore, the bending channel 30 increases the flowability of the engine oil, allowing it to pass through the middle of the heat-absorbing block 5, increasing the contact area between the oil and the heat-absorbing block 5, thereby improving cooling efficiency and effect.

[0034] When using an engine oil cooler according to this embodiment, the oil circulation pipe 1 is connected to the engine to circulate the oil. At this time, the flow pipe 4 is connected to an external cooling medium, which flows within the cooling housing 3, enveloping the oil circulation pipe 1. The heat-absorbing connecting shaft 6 and the heat-absorbing block 5 absorb heat from the oil. Simultaneously, the heat-absorbing connecting shaft 6 is located within the cooling medium, which carries away the absorbed heat, thereby continuously cooling the oil. Two temperature sensors 2 detect the oil temperature before and after cooling, and a preset value is set. If the oil... If the temperature drops below the preset value after cooling, it indicates that the oil temperature is currently low and the entire heat absorber block 5 does not need to contact the oil. At this time, the drive unit 11 is activated, driving the second rotating drum 12 to rotate. Through the connection of the traction rope 9, the first rotating drum 8 is driven to rotate, causing the drive shaft 7 and the heat absorber connecting shaft 6 to rotate. This causes the heat absorber block 5 to rotate 90 degrees, placing it horizontally within the heat absorption circulation pipe to increase the heat exchange area and thus improve the oil cooling efficiency. When the temperature is detected to be below the preset value, the heat absorber block 5 is reset, placing it vertically within the oil circulation pipe 1. Figure 2 and Figure 5 As shown, the heat absorber block 5 has a large flow space on both sides, thereby increasing the fluidity of the engine oil and increasing the oil flow rate, allowing the engine oil to enter the engine more quickly and complete a cooling cycle. With the above structural design, when the engine oil temperature is higher than the preset value, the heat absorber block is placed horizontally to increase the heat exchange area and improve the cooling effect; when the temperature is lower than the preset value, the heat absorber block can be placed vertically to increase the oil flow rate, improve the oil circulation efficiency, and improve the cooling effect and cooling efficiency, thus flexibly adapting to various situations of engine oil cooling.

A person skilled in the art will understand that all or part of the processes of the above embodiments and equivalent changes made in accordance with the claims of the present application are still within the scope of the present application.
