Description

Technical Field

[0001] This utility model relates to the field of engine design and manufacturing, and in particular to an oil cooler structure that reduces flow resistance. Background Technology

[0002] With increasing demands from socio-economic activities for vehicle power, economy, and adaptability, lightweighting, safety, applicability, and reliability of vehicles and their components have become widely recognized areas for improvement. Current engine operating conditions are extremely harsh, placing high demands on the lubrication of moving parts. Insufficient lubrication of components leads to reduced oil pressure, which is quite dangerous for the engine and can cause failures such as bearing failure. Therefore, ensuring the safety and reliability of the engine lubrication system is crucial. Traditional engine oil coolers, generally speaking, often have high oil resistance, resulting in low oil pressure and insufficient oil volume, leading to inadequate engine lubrication and a high risk of bearing failure. Traditional engine oil coolers have significant resistance in their oil passage design and filter elements, resulting in high overall flow resistance, which in turn leads to low oil pressure. Therefore, there is an urgent need for an oil cooler structure that reduces flow resistance to address the current problems of insufficient engine oil pressure and bearing failure.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide an oil cooler structure that reduces flow resistance, which can effectively improve engine reliability, reduce flow resistance, increase oil pressure, and ensure engine safety.

[0005] To achieve the above objectives, this utility model provides an oil cooler structure with reduced flow resistance, including a cooler body, a stop valve, a temperature control valve, a filter element, and multiple cooling cores. The stop valve is located inside the cooler body and includes a stop valve inlet, which communicates with the oil outlet of the engine body. The high-temperature engine oil generated during engine operation enters the oil passage of the cooler body through the stop valve inlet. The temperature control valve is located inside the cooler body and includes a temperature control valve inlet, which is used to receive the high-temperature engine oil from the engine body. The filter element is located inside the cooler body and is used to filter impurities in the high-temperature engine oil. The filter element includes a central tube, which is used to deliver lubricating oil to the parts of the engine body that require lubrication. Multiple cooling cores are located inside the cooler body and are used for heat exchange between the high-temperature engine oil and the cooling medium, thereby cooling the high-temperature engine oil. Each cooling core includes multiple oil holes.

[0006] In a preferred embodiment, the stop valve further includes a valve core opening, which is disposed at the valve core of the stop valve.

[0021] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0022] like Figures 1 to 2 As shown, a preferred embodiment of the present invention provides a flow-resistance-reducing oil cooler structure, comprising a cooler body 100, a stop valve 1, a temperature control valve 2, a filter element 3, and multiple cooling elements 4. The stop valve 1 is disposed inside the cooler body 100 and includes a stop valve inlet 1-1, which is connected to the oil outlet of the engine body. High-temperature engine oil generated during engine operation enters the oil passage of the cooler body 100 through the stop valve inlet 1-1. The temperature control valve 2 is disposed inside the cooler body 100, and the temperature... The control valve 2 includes a temperature control valve inlet 2-1, which is used to receive high-temperature engine oil from the engine body; the filter element 3 is installed inside the cooler body 100, and is used to filter impurities in the high-temperature engine oil. The filter element 3 includes a central tube 3-1, which is used to deliver lubricating oil to the parts of the engine body that need lubrication; multiple cooling cores 4 are installed inside the cooler body 100, and are used for heat exchange between the high-temperature engine oil and the cooling medium, thereby cooling the high-temperature engine oil. The cooling cores 4 include multiple oil holes 4-1.

[0023] In some implementations, when the engine stops, the check valve 1 closes the oil inlet from the oil pump to prevent oil in the oil filter from flowing back into the oil pan. This allows the lubrication system to quickly build up oil pressure when the engine restarts, preventing component wear due to insufficient oil supply during startup and improving engine reliability.

[0024] In some implementations, the thermostatic valve 2 can automatically adjust the flow of engine oil based on the oil temperature. During a cold start, when the engine oil temperature is low and its viscosity is high, the thermostatic valve 2 automatically opens, allowing the oil to bypass the oil cooler and directly enter the engine for rapid lubrication, thus reducing engine wear. When the oil temperature rises to a certain level (typically 80℃-90℃), the thermostatic valve 2 precisely closes, guiding the oil through the oil cooler for heat dissipation, ensuring the oil remains within its optimal operating temperature range of 50℃-80℃. Furthermore, if the oil cooler is blocked or damaged, preventing normal oil flow, the thermostatic valve 2 automatically opens an emergency channel to prevent a sudden drop in oil pressure and avoid serious engine damage due to poor lubrication.

[0025] In some embodiments, the stop valve 1 further includes a valve core opening 1-2, which is disposed at the valve core of the stop valve 1. The valve core opening 1-2 can adjust the flow resistance and flow distribution of the oil by changing the opening width, so that the flow of the medium oil tends to be uniform in various areas of the cooler.

[0026] In some embodiments, the diameter of the stop valve inlet 1-1 is increased from the original φ33mm to between φ34mm and φ36mm, for example, but not limited to φ35mm. The height of the valve core opening 1-2 is increased from the original 9.8mm to between 12.5mm and 13mm, for example, but not limited to 12.8mm. This design is expected to reduce the pressure by approximately 10 kPa.

[0027] In some implementations, the diameter of the oil inlet 2-1 of the temperature control valve is increased from the original φ60mm to between φ64mm and φ66mm, for example, but not limited to φ65mm, while keeping the installation interface unchanged, and it is expected to reduce the pressure by about 10 to 15 kPa.

[0028] In some embodiments, the diameter of the central tube 3-1 of the filter element 3 is increased from the original φ31.6mm to between φ34mm and φ36mm, for example, but not limited to φ35mm, which is estimated to reduce the resistance by about 20Kpa.

[0029] In some embodiments, the width of the cooling core 4 is increased from the original 85mm to between 94mm and 96mm, for example, but not limited to 95mm, and the diameter of the oil hole 4-1 of the cooling core 4 is increased from the original φ20mm to between φ21mm and φ23mm, for example, but not limited to φ22mm. This is expected to increase heat dissipation and reduce oil resistance, with an expected resistance reduction of about 15Kpa.

[0030] By taking the above measures, the overall oil resistance can be reduced by 50 kPa, thereby increasing the oil pressure and ensuring engine performance.

[0031] In summary, the oil cooler structure of this utility model with reduced flow resistance has the following advantages: This application reduces inlet flow resistance by enlarging the stop valve structure; it also adopts a structure with an enlarged temperature control valve, which is simple, reasonable, and novel, further reducing flow resistance; by enlarging the filter element's central tube structure, it ensures smooth oil intake and increases oil pressure; and by increasing the width of the cooling core and the diameter of the oil passage, it reduces flow resistance. The oil cooler structure of this utility model with reduced flow resistance is simple, reasonable, and novel, effectively improving engine reliability, reducing flow resistance, increasing oil pressure, and ensuring engine safety.
