The characteristics of heat transfer and pressure drop of a oil cooling heat exchanger are studied through experimental measurement, the experimental formula are given for these two parameters. The convection heat transfer coefficients of both oil and water side are derived by means of separating variables from fitting curve method.The main factors affecting the heat transfer capability of the exchanger are pointed out. Solving methods are proposed which are benificial to the improvement of the transfer capability of the heat exchanger.
