The study was based on the evaporator of small air cooler of the cold storage.Using hot tinning process of copper-constantan thermocouples,many temperatures of finned tube surfaces were measured.Converting equation of temperature and thermo-emf for thermocouples was computed based on matlab software and other points of the evaporator temperature were computed by using griddata3 D-value estimation function and image of 3D temperature field.Meanwhile,the temperature distribution of exterior and interior for evaporator visualizing analysis became realizable and provided the basis for the heat transfer effect analysis of the cold storage evaporator.
