Comparative Study on Heat Transfer Performance of Coolant Based on Cooling Rate Experiments
Cooling performance of coolants with 6 different types and contents of additives is studied through cooling rate experiments.The result shows that the cooling performance of the coolants with the nonionic additive is the best,followed by the coolants with the mixed additive,and the coolants with the ionic additive exhibits the worst cooling performance.The lower the additive content,the better the cooling performance of the coolant.The cooling performance of coolant A containing 0.11%non-ionic addifive by mass is the best,with the shortest time corresponding to the probe temperature reaching 200℃,which is 6.1 s and the maximum cooling rate reaches 60℃/s.
