Abstract
The stacked heat exchanger of the present invention has a structure wherein grooves are brazed together to seal the external surface of the coolant passage, further grooves are brazed together to form a partition between the straight incoming and outgoing flow passages, and least one groove in the straight incoming and outgoing flow passage section which groove runs in parallel with the grooves earlier mentioned is formed on the formed plates. With this structure, drain water flows down promptly through these grooves and the splashing of the drain water into the downstream area of the heat exchanger can be prevented.
