PROBLEM TO BE SOLVED: To obtain a double heat exchanger in which radiation capacity of one heat exchanger can be regulated without increasing the size. SOLUTION: Second fluid channels of tubes 2A, 2B constitute the conduction passage of a radiator and the first fluid passage 6 of the tube 2B constitutes the conduction passage of a condenser. The number of conduction passage of the condenser is lower than the number of conduction passage of the radiator. Consequently, the core area of the condenser is smaller than that of the radiator and radiation capacity of the condenser can be regulated without increasing the size and the mass of a double heat exchanger more than required. |
