Abstract: To achieve the high freshness-preserving function of a refrigerator, higher requirements are imposed on the temperature uniformity inside the crisper drawer. The built-in crisper drawer of a refrigerator's refrigeration compartment is taken as the research object, its air supply duct structure is optimized by combining temperature field simulation, and the results are compared with the test data of physical prototypes.The results indicate that with the adoption of the tree-shaped air duct and the optimized air direction of the multi-hole air outlet, the maximum temperature difference in the internal space of the drawer reached 1.1 ℃. Furthermore, when compared with the measured results of two physical prototypes, the deviation of the maximum temperature difference between the simulation and the prototypes is ≤0.2 ℃. The findings of the study provide basic data reference for the subsequent technical research on crisper drawer.
