Abstract: Currently, most beauty refrigerators on the market utilize semiconductor chips to achieve refrigeration, but they generally suffer from poor refrigeration effects and uneven temperature distribution. There is limited research on this phenomenon, and relevant research literature is rarely seen. By starting from factors such as fan speed, clearance between the fan and components, and spacing between cold conductors and radiator fins. Through CFD simulation technology, it conducts simulation analysis of the airflow inside and outside the refrigerator to determine optimization schemes. By making prototypes, it tests and verifies key performance indicators such as storage temperature, power consumption, and noise. Then, it performs fitting and verification with simulation results, iteratively correcting the simulation accuracy. The final experimental results show good consistency. CFD simulation technology can provide technical support in the early stages of product design, reducing unnecessary technical verification and thus shortening the product development cycle.
