Abstract
A heat exchanger has plural tubes and a header tank formed by a first tank portion and a second tank portion. When the first tank portion and the second tank portion are assembled, a protruding portion protruding from a wall of the first tank portion is inserted into a hole formed in the second tank portion. Then, the first tank portion is slidably moved against the second tank portion in a parallel direction with respect to a longitudinal direction of the header tank until the protruding portion engages the hole. As a result, the second tank portion is partially clamped between the wall of the first tank portion and the protruding portion, and the first and second tank portions sufficiently contact each other. Therefore, undesirable clearance is restricted from being formed between the first and second tank portions, and brazing performance therebetween is improved.
