Working principle of automobile oil cooler

The function of the oil cooler is to cool the lubricating oil and maintain the oil temperature within the normal operating range. On high-power reinforced engines, due to the high heat load, an oil cooler must be installed. When the engine is running, the viscosity of the oil decreases as the temperature increases, reducing the lubrication capacity. Therefore, some engines are equipped with oil coolers, which are used to lower the oil temperature and maintain a certain viscosity of the lubricating oil. The oil cooler is arranged in the circulating oil circuit of the lubrication system, and its working principle is the same as that of the radiator.

Causes and solutions of oil cooler faults

Reason for malfunction:

The most common cause of malfunction is inferior oil. Oil deterioration caused by prolonged use and delayed oil change. After prolonged use, the oil will lose its characteristics, unable to lubricate the engine properly, and will reach temperatures higher than allowed. The cause of the malfunction may also be the failure of the oil cooler itself due to material wear.

Solution:

The car should be replaced promptly after driving 5000 kilometers or six months. It is recommended to check the cooler assembly for oil leakage when changing the oil.

SuKoTec oil cooler assembly product advantages:

Heat dissipation performance

The SuKoTec cooler body material is made of 3003 aluminum alloy brazing process, which is as sturdy as OE, with a minimum dimensional tolerance of 0.05mm. The surface is smooth, with good airtightness, stable shape and size, and can ensure appropriate lubricating oil cooling to meet the operational requirements of the engine.

Quality assurance

1. The filter cartridge shell adopts the globally renowned brand DuPont PA66+35% GF.

2. The shell and cooler are sealed with fluororubber sealing rings, which have excellent flame retardancy, airtightness, high temperature resistance, oil resistance, solvent resistance, flame resistance, chemical resistance, and climate resistance.

Reliability and performance

The production process of the oil cooler is 100% fully inspected and subjected to a withstand voltage pulse test at an output pressure of up to 10.0 bar.
