A double heat exchanger includes a radiator (200) having a radiator tank (220, 230) and a radiator core portion (210), and a condenser (100) having a condenser tank (120, 130) and a condenser core portion (110). The radiator tank and the condenser tank are integrally connected by a connection portion (400, 400A, 400B) protruding from the radiator and the condenser tanks toward the radiator and condenser core portions. Therefore, the connection portion is cooled by air passing through the radiator and condenser core portions. Thus, it can restrict heat from the radiator tank from being transmitted to the condenser tank through the connection portion, thereby preventing heat-exchanging capacity of the condenser from being decreased in the double heat exchanger. <IMAGE> |
