The Oil Cooler Core 4W-4980 is specifically designed for CAT 3512 engines, playing a crucial role in ensuring their stable operation. Here is an introduction: ### Basic Information - **Part Number**: 4W-4980 - **Brand**: Caterpillar (CAT) - **Type**: Shell and tube oil-water cooler - **Dimensions**: Height 241.3 mm, Width 248.9 mm, Length 848.4 mm ### Function The 4W-4980 oil cooler core is responsible for cooling the engine oil. As the engine runs, the oil absorbs a large amount of heat. This core uses a **water-cooling principle**. It transfers the heat from the oil to the coolant through efficient heat exchange, keeping the oil within an optimal working temperature range, typically between 80 - 110°C. This ensures that the oil maintains good lubrication performance and fluidity, reducing wear on engine components and prolonging the engine's service life. ### Structure and Working Principle - **Structure**: It features a sturdy anddesigned aluminum alloy housing, which is lightweight and has excellent thermal conductivity. Inside, there are copper core tubes, which are the key components for heat exchange. The tubes are surrounded by fins that greatly increase the surface area for heat dissipation. - **Working Principle**: High-temperature oil from the engine flows into the copper core tubes of the 4W-4980. At the same time, coolant from the vehicle's cooling system flows in the opposite direction outside the tubes. This counterflow design maximizes heat transfer, allowing heat to move from the hot oil to the cold coolant. The copper core tubes quickly conduct the oil's heat to the tube walls, and the fins help the coolant absorb the heat more quickly and thoroughly. ### Performance Advantages - **Stable Temperature Control**: In high-temperature working environments, such as mining operations with an ambient temperature of 45°C, after 10 hours of continuous high-intensity work, the 4W-4980 can stably control the oil temperature at around 100°C, keeping it within the ideal range. - **Reduced Wear**: Compared to engines without the 4W-4980 oil cooler core, the wear rate of key components in engines equipped with it is reduced by about 30%. This effectively extends the engine's maintenance cycle and service life. - **Improved Efficiency**: In construction sites, cranes equipped with CAT 3512 engines and the 4W-4980 oil cooler core can increase the number of lifting operations by about 15% in the same period due to stable oil temperature control, improving work efficiency. In summary, the Oil Cooler Core 4W-4980 is an essential component for CAT 3512 engines, providing reliable oil cooling and ensuring the engine's optimal performance under various working conditions.
