Abstract
A heat exchanger includes tubes layered in a layering direction, a side plate arranged most outside of the tubes in the layering direction, and a core plate extending in the layering direction. The side plate has an end portion in a longitudinal direction, and the core plate has a wall portion extending in the longitudinal direction. The end portion of the side plate has a brazing section brazed to an outer face of the wall portion of the core plate, and the end portion of the side plate has a through hole located in the brazing section.
Claims10
A heat exchanger comprising:
- a plurality of tubes layered in a layering direction;
- a reinforcing side plate arranged most outside of the tubes in the layering direction, the side plate extending in a longitudinal direction of the tube;
- a core plate extending in the layering direction, a longitudinal end of the tube being connected to the core plate;
- and
- a tank connected to the core plate, wherein
- the side plate has an end portion in a longitudinal direction of the side plate, and the core plate has a wall portion extending in the tube longitudinal direction, the wall portion being located on an end portion of the core plate in the layering direction,
- the end portion of the side plate has a brazing section brazed to an outer face of the wall portion of the core plate, and
- the end portion of the side plate has a through hole located in the brazing section.
