ABSTRACT:
In order to enhance the working efficiency of assembling a heat exchanger in which two types of heat exchangers are integrated, there is provided a heat exchanger in which the size of the dummy tubes, which are the third tubes arranged in the portion between the first and the second radiator, and that of the first and the second tubes are made to be the same and further the size of the fins arranged between the dummy tubes and that of the first and the second fins are made to be the same. In order to reduce the occurrence of defective brazing of the separator to the header tank and in order to make it possible to easily repair the defective brazing portion, there is provided a hole in a portion of the header tank.
