Oil Cooler
Oil Cooler is a means to maintain a relatively low temperature so that the lubricating oil heat accelerated. It means mounting the object is to prevent the lubricating oil temperature increases lead to weakened. According to different cooling medium, the oil cooler can be divided into two kinds of air-cooled and water-cooled. Air flow generated during traveling of the vehicle using the air-cooled engine oil cooling. Typically water-cooled water tank installed in the vehicle interior or c cooling water systems, heat exchange between water and cooling by, for cooling the hot oil. Type oil cooler
1) air-cooled oil cooler
The air-cooled oil cooler and a cooling tube was cooled by a number of core plates, when traveling in a car by cooling the hot wind oncoming car oil cooler core. Air-cooled oil cooler requirements around good ventilation in the ordinary cars difficult to ensure adequate ventilation space, seldom used. With this mostly on the car cooler, because of the high speed racing, a large quantity of cooling air.
2) a water-cooled oil cooler
placed in a cooling water passage in the oil cooler, using cooling water temperature to control the temperature of the lubricating oil. When the oil temperature is high, cooling by cooling water, the engine start, the cooling water absorbs heat from the rapid increase in the lubricant temperature. Oil cooler housing cast from an aluminum alloy, the front cover, back cover and a copper core tube. To enhance cooling, the outer tube and a fin set. Cooling water flowing outside the tube, the flow of the lubricating oil in the tube, both for heat exchanger. We have the oil flow in the outer tube, and then the water flowing through the pipe structure.
2, core material
The oil cooler core material requirements are relatively high, need to meet these two stripsMember, a strong corrosion resistance and heat dissipation. Therefore, the oil cooler core material are generally two types: copper and stainless steel, copper is the preferred stainless steel is secondly, because the corrosion resistance and heat resistance of stainless steel to be worse.
