PROBLEM TO BE SOLVED: To obtain an indirect cooling refrigerator in which temperature fluctuation of inner air is eliminated by making uniform heat transfer from primary cooling air into the refrigerator. SOLUTION: Back and side heat transfer passages 10, 12 for supplying cold heat are provided along the back wall 9 and the left and right side walls 11 in a refrigerator. A chill supply passage 13 is sectioned in the back of the passage 10 and when primary cooling air delivered from an evaporator 7 is guided through the passage 13, cold heat of the primary cooling air is released upward and distributed simultaneously to the back and side heat transfer passages 10, 12. Since primary cooling air of same temperature is suppled to both heat transfer passages 10, 12, the back wall 9 and the side walls 11 can be cooled down to same temperature. Consequently, the inside of refrigerator is cooled uniformly and high humidity state can be sustained. |
