A heat exchange process analysis method for a finned tube sodium-air heat exchanger comprises the following steps: modeling the finned tube sodium-air heat exchanger to obtain a heat exchanger model; grid division is conducted on the heat exchanger model to generate a grid model; selecting a calculation model and an algorithm adapted to the calculation model; and calculating the gridding model by using the algorithm to obtain a temperature field state and/or a flow field state of the heat exchanger, wherein modeling of the finned tube sodium-air heat exchanger comprises the steps that a finned heat exchange tube bundle of the finned tube sodium-air heat exchanger is modeled, and fins of each heat exchange tube of the finned heat exchange tube bundle are modeled as an equivalent porous medium model. According to the heat exchange process analysis method of the heat exchanger, related simplification is conducted on the structure of the heat exchanger in the modeling process of the heat exchanger, the modeling p
