The utility model relates to a direct cooling refrigerator, it includes: inject the box that has room between the storing, including being used for forming its outside case shell, being used for forming its inside inner bag and the foaming layer of formation between case shell and inner bag, a heat transfer device sets up in the foaming layer for producing cold volume to paste the back wall outside of locating the inner bag, and supplementary heat exchange assemblies, set up in room between the storing to it is inboard to paste the back wall of locating the inner bag, in order allowwing cold volume that heat transfer device produced back wall transmission to the supplementary heat exchange assemblies through the inner bag, then carries out the heat exchange through indoor air between supplementary heat exchange assemblies and storing. Supplementary heat exchange assemblies's design increased and the air between area of contact, improved heat exchange efficiency, reduced the energy consumption, reached energy -conserving purpose. Simultaneously the utility model discloses can require lowerly to heat transfer device's non -corrosibility, control the cost strictly. The direct inboardof establishing wall behind the inner bag of pasting of supplementary heat exchange assemblies, simple structure realizes easily that technology maneuverability is stronger.
