HEAT EXCHANGER

摘要

A heat exchanger includes a core unit having a plurality of pipe members arranged in parallel, a pair of tanks joined to the core unit to sandwich the core unit from opposite sides in a longitudinal direction of the pipe members and communicating with the pipe members, and a partition plate for closing a cross-section of the tank. The partition plate includes a recess on an outer edge portion to be held in contact with an inner wall surface of the tank, the tank includes a projection to be engaged with the recess on the inner wall surface, and the projection and the recess are formed by plastic working a part of the tank in contact with the partition plate from an outer side toward an inner side of the tank in a state where the partition plate is arranged in the tank.

1. A heat exchanger, comprising:
a core unit including a plurality of pipe members open at opposite ends and arranged in parallel; a pair of tanks joined to the core unit to sandwich the core unit from opposite sides in a longitudinal direction of the pipe members and communicating with the pipe members; and a partition plate for closing a cross-section of the tank intersecting with a pipe member arrangement direction, wherein: the partition plate includes a recess on an outer edge portion to be held in contact with an inner wall surface of the tank; the tank includes a projection to be engaged with the recess on the inner wall surface; and the projection and the recess are formed by plastic working a part of the tank in contact with the partition plate from an outer side toward an inner side of the tank in a state where the partition plate is arranged in the tank.
