Abstract
A structure for mounting an oil cooler to a heat-exchanger tank is disclosed. A long-scale oil cooler is received in a heat-exchanger tank, and pipe portions are formed only on one side of the oil cooler so that the pipe portions are inserted respectively in pipe holes formed in the tank. A support portion for supporting the other side of the oil cooler where no pipe portion is formed is formed on an inner surface of the tank. Further, a laminate type oil cooler is provided. The oil cooler has a core portion in which a plurality of shells each having an oil flow path formed therein are laminated. A first oil passage hole is formed at a first side end of the core portion, and a second oil passage hole is formed at a second side end of the core portion. The laminated shells are made to communicate with each other by the first and second oil passage holes. Further, a third oil passage hole is formed between the first oil passage hold and the second oil passage hole in a width direction of the core portion. Only a part of all laminated shells in a lamination direction of the shells are made to communicate with each other by the third oil passage hole. Further, a blocking member is disposed in the oil flow path of the shell having the third oil passage hole so as to block oil flow, the blocking member being disposed between the third oil passage hole and the first oil passage hole.
