文摘Curve fitting method is often used in the test of heat transfer performance of heat exchangers.The convective heat transfer coefficient may be obtained with the method.However,there are defects with the method.The new curve fitting method introduced in this paper is a practical method for test of convective heat transfer coefficient.There are few constraint with the method.Moreover,the results are more precise and the test is more convenient.The method is expecially suitable for test of convective heat transfer coefficient of finned tubes outer surface.An instance of use of the method is given.
