Hydraulic Experimental Research of New Type Heat Exchanger

New type heat exchanger consists of five cell subassemblies. Hydraulic experiment of new type heat exchanger is divided into two parts: separated effect experiments and integral hydraulic simulation experiments. The separated effect experiments simulate four kinds of passages, from which the correlations of pressure drop is obtained. Simulation scale of integral hydraulic simulation model is 1:1, and some components is simplified. By the experiments, flow rate distribution of the primary side and resistance coefficients of the different components are determined. All data obtained have been used to improve the design of new type heat exchanger.
