This Engine Oil Radiator is a key heat-dissipating component designed for the lubrication systems of diesel engines in heavy-duty construction machinery, including excavators, loaders, and bulldozers. Acting as the "oil temperature control valve" of the equipment, it utilizes circulating coolant to exchange heat with high-temperature engine oil, removing the significant thermal energy absorbed during lubrication. This ensures the oil maintains appropriate viscosity and lubricating performance under high-temperature conditions, preventing severe failures such as thinning oil films, lubrication failure, excessive engine wear, or cylinder scuffing caused by overheating. It guarantees stable equipment operation under heavy-duty and harsh working conditions, such as those found in mining and construction sites.
High-Strength Cast Iron Housing:
The housing is precision-cast from high-strength cast iron with a dense internal structure. This material offers excellent compressive strength and rigidity, enabling it to withstand the bidirectional pressure shocks from both oil and coolant circulation. This ensures the housing remains deformation-free and crack-free under long-term heavy loads and high temperatures, protecting the internal core.
Low Carbon Steel Tube & Fin Core:
The internal heat exchange core is assembled from low carbon steel tubes and fins using a vacuum brazing process. This technique ensures atomic-level bonding between the tubes and fins, resulting in tight contact and extremely high heat transfer efficiency. It rapidly transfers heat from the oil to the coolant, achieving effective thermal exchange.
Passivated Core Surface:
The surface of the heat exchange core undergoes passivation treatment, forming a dense chemical protection film. This enhances corrosion resistance and effectively prevents scale and sludge from adhering to the tube walls, ensuring long-term efficient heat dissipation and smooth oil flow.
Yellow Anti-Corrosion Coating:
The exterior surface is treated with yellow anti-corrosion spray paint, offering strong adhesion, weather resistance, and corrosion protection. It effectively resists moisture, dust, and corrosive media in mining environments, preventing housing rust and extending service life.
Precision Machined Flange Surface:
The mounting flange surface is precision machined to achieve high flatness. This ensures a tight fit with the engine block and allows for leak-proof sealing with the gasket, preventing the dangerous mixing of oil and coolant (which can lead to catastrophic engine failure).
Rigorous Pressure & Seal Testing:
Every oil radiator undergoes strict pressure testing and sealing performance testing before dispatch. We validate its pressure-bearing capacity under simulated high-temperature and high-pressure conditions to ensure zero leakage and no deformation.

Installation Recommendation:
Thoroughly clean the engine oil passages and coolant lines before installation. Use a brand-new gasket and tighten bolts evenly in a diagonal sequence. After installation, check oil and coolant levels, start the engine, and warm it up to normal operating temperature. Inspect for any signs of leakage to ensure the oil and coolant remain completely separate with no mixing.
