Abstract:
The frost-free freezer relies on the fan to motivate the internal airflow to achieve the cooling in the cabinet. By optimizing the air duct structure,the thermal environment can be significantly improved. In this paper,the CFD simulation software is used to visualize the internal temperature field and airflow organization of the freezer,and to explore the influence of the air duct structure on the thermal performance. By changing the position of the fan,the widths of the air duct and the inclination angles of the air duct,several models are established for comparison,and the optimal structure model is selected. The results show that:the internal thermal performance of the freezer with the fan perpendicular to the ground,the air duct is 8 cm and the inclination angle is of 1.8° is the most ideal.
