Effect
is a cooling lubricant oil cooler, the oil temperature remains within the normal working range. In the high-power engine strengthening due to the large thermal load, it must be fitted with an oil cooler. When the engine is running, due to the oil viscosity thinning with increasing temperature, reducing the lubricating ability. Thus, some engines fitted with the oil cooler, which function is to reduce the oil temperature, to maintain a certain viscosity of the lubricant. Oil cooler disposed in the lubricating oil circulation system.
1. air-cooled oil cooler
The air-cooled oil cooler and a cooling tube was cooled by a number of core plates, when the vehicle is traveling by car relative wind of the cooling heat 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. The 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.
