Oil cooler is a kind of oil cooling equipment widely used in hydraulic system and lubrication system. By using this equipment, the heat exchange between two kinds of fluid media with a certain temperature difference can be realized, so as to reduce the oil temperature and ensure the normal operation of the system.
1. The water-cooled oil cooler uses water as the medium to exchange heat with oil. The advantage is that the cooling effect is better and it can meet the requirement of low oil temperature (the oil temperature can be reduced to about 40 ℃. The disadvantage is that it can only be used in the place with water source.
2. Air cooled oil cooler uses air as medium and oil for heat exchange. Its advantage is that air is used as cooling source, and it is not limited to the place where it is used. Moreover, it is environmentally friendly. Its disadvantage is that due to the influence of ambient temperature, when the temperature is high, the oil temperature can not be reduced to the ideal temperature (generally, it is difficult to reduce the oil temperature to 5 ~ 10 ℃ higher than the ambient temperature).
