High-quality oil cooler cores ME034561 and ME074185 are suitable for diesel engines 6D14/15/16.

High-quality oil cooler cores ME034561 and ME074185 are suitable for diesel engines 6D14/15/16.

High-quality oil cooler cores are key components in the lubrication system of diesel engines. They are primarily used to stably control the oil temperature within the ideal range of 70~90℃ through forced cooling, maintaining the viscosity stability and lubrication effect of the lubricating oil. Their core function is to prevent viscosity decrease and lubrication performance degradation caused by excessively high oil temperature through an efficient heat exchange mechanism, making them particularly suitable for the heavy-load conditions of high-power diesel engines.

Main Types and Structural Features

Water-cooled oil coolers consist of a core (containing brass tubes, fins, and gaskets) and a shell. Oil flows in the space between the core and the shell, while cooling water circulates inside the core. The cooling water carries away heat, achieving precise temperature control (typically 80±5℃). This structure fully utilizes the engine cooling system, resulting in high heat exchange efficiency.

Technical Standards for High-Quality Oil Cooler Cores

Materials and Manufacturing Processes: Utilizing high thermal conductivity materials (such as brass tubing) and optimized fin design to enhance heat exchange efficiency.

Sealing: High-quality gaskets and welding processes prevent the coolant from mixing with the engine oil, avoiding leaks.

Compatibility: Must meet engine operating requirements; for example, heavy-duty diesel engines require cores with higher cooling capacity.

The selection of a high-quality oil cooler core should be based on engine type (e.g., water-cooled/air-cooled) and operating conditions to ensure its cooling performance matches the engine, extending engine life and maintaining efficient operation.
