Heat exchanger

摘要

A heat exchanger having at least one collecting tank which extends in a longitudinal direction and which comprises a plate and a cover, wherein the plate has, at least one of its edge regions running in the longitudinal direction, a rim by means of which the plate engages at the outside over an edge region, which runs in the longitudinal direction, of the cover, or wherein the cover has, at least one of its edge regions running in the longitudinal direction, a rim by means of which the cover engages at the outside over an edge region, which runs in the longitudinal direction, of the plate. The respective rim have, in the longitudinal direction, a multiplicity of calked portions by means of which said rim, in the region of each individual calked portion, is deformed in the plate and the cover to one another.

主权项

1. A heat exchanger comprising:
at least one collecting tank that extends in a longitudinal direction and comprises a base and a cover, the base at least one of its edge regions runs in the longitudinal direction; and a rim via which the base overlaps on an outside of an edge region running in the longitudinal direction of the cover or whereby the cover at least one of its edge regions running in the longitudinal direction has a rim via which the cover overlaps on the outside an edge region running in the longitudinal direction of the base, wherein the respective rim is substantially linear in the longitudinal direction and is devoid of tabs or projections, wherein portions of the substantially linear rim are deformed in the direction of the collecting tank center to fix the base and the cover to one another, each deformed portion of the substantially linear rim forming a peened portion, such that a plurality of peened portions are provided, and wherein at least one area of the substantially linear rim has peened portions having a greater width than peened portions in other areas of the substantially linear rim.
