  • Heat exchanger
    Publication number: 20030141046
    Abstract: A protective cover 7 is disposed on an airflow upstream side of a tube 2. Even when relatively large flying materials such as gravel impinge against a radiator 1, the flying materials are prevented from directly striking the tubes 2. As the tube 2 can thus be protected from the relatively large flying materials such as gravel, the radiator 1 can continue operating, and the reliability of the radiator 1 can be improved.
