چکیده
A model for heat-exchangers of heat-setting machine is proposed. First, techniques of heat exchangers in heat-setting machines is introduced. Then on basis of Newton cooling law, heat transfer formula is proposed. Third, three heat damps between oil, tube body and air are introduced respectively. According to basic heat transfer theory, equation for temperatures of heated air is obtained. Practice data and simulating data are compared and mean and variance are calculated. Result shows that error is less than 2%, which means high precision of the proposed model.
