Experimental Study for Heat Transfer Enhancement of Oil Cooler

The heat transfer experimental study for three integral pin-fin tube oil coolers is performed.The experimental results indicate that for the same oil mass flow rate,when the tube number of pin-fin tube oil cooler is half that of smooth tube,the heat transfer coefficient of pin-fin tube oil cooler is 2.2 times that of bar tube.The experimental results indicate that the pin-fin tube oil cooler is of less tube plate and better heat transfer characteristics
