Abstract
The structural layout of heat exchanger has significant impact on the airflow filed distribution of the indoor unit of split air conditioner, which in turn affects the heat transfer performance and outlet flow rate of the heat exchanger. In this paper, a 3D CFD model was established for a three-stage fin and tube heat exchanger with different configurations by employing CFX in ANSYS. Through numerical simulation, the streamlines distribution of the airflow, the heat flux of the fin wall as well as the heat transfer coefficient between the fin wall and the air were analyzed in detail.关键词
