1. The water-cooled oil cooler uses water as the medium for heat exchange with oil. The advantage is that the cooling effect is relatively good, which can meet the requirements of relatively low oil temperature (the oil temperature can be reduced to about 40 ℃), and the disadvantage is that it can only be used where there is a water source.
2. The air-cooled oil cooler uses air as the medium and oil for heat exchange. The advantage is that it uses air as the cooling source, which is basically not limited to the place of use, and it is environmentally friendly. The disadvantage is that due to the influence of the ambient temperature, the oil temperature cannot be reduced to the ideal temperature when the temperature is high (air cooling is generally difficult to reduce the oil temperature to only 5~10 ℃ higher than the ambient temperature).
