Abstract

The stacked heat exchanger in accordance with the present invention comprises flat tubes and corrugated fins which are alternately put together, the flat tube having a tank portion and a core portion, the tank portion on one side at the outermost portion having an inlet header, the tank portion on the other side at the outermost portion having an outlet header, and the core portion having a side plate as an external plate at both ends, wherein the upper end of the side plate abuts against the lower end of the inlet header and the lower end of the outlet header. Therefore, when a pressure is applied, a force in the spreading direction applied to the inlet/outlet tank portion is received by the abutting of side plate against said inlet and outlet headers. Thus, the deformation of the whole stacked heat exchanger can be prevented.
