Thermal performance simulation and experimental study of elliptical tube finned evaporator

Establishes a test bench and conducts experimental tests on the customized elliptical tube and circular tube finned evaporators. Simulates the thermal performance of above two types of finned evaporators with CFD, and analyses the performance advantages of elliptical tube finned evaporator comprehensively. With a certain cooling capacity and neglecting the difficulty of processing, the air conditioning unit with elliptical tube finned evaporator, can not only reduce the number of evaporator rows and the air resistance of the evaporator by 33%, but also reduce the aluminum consumption by 20.6% and the copper consumption by 1.4%, with more compact and better economy.
