oil cooler

The main objective of oil cooler is to dissipate the heat from lubricating oil Fig. 3.1. Oil cooler is a simple heat exchanger oil coolers nd are generally used in heavy vehicles. Where temperature of oil flow raises it cause the
decrease in viscosity of the lubricating oil, and the oil film in the bearing might break. To avoid such type of situation heavy engines are provided with oil coolers.Water type cooler is more common because it can be used as reversible cooler. According to the requirement it is used as in initial stage when oil should not be cooled, rather there is necessary that lubrication oil goes to all lines during starting of engine so that there is less wear and tear of engine, so that complete circulation of oil is take place.

Because water is hotter than oil where cooler will initially heat the oil and when higher temperature is reached the reverse process is started which will cool the oil so that oil film does not break and to maintain the viscosity of oil.
