A heat exchanger for an internal combustion engine may include a base tube and a flange extending at least partially around the base tube. The flange may be formed as a forged piece.

Heat exchanger

A heat exchanger may include a tubular housing, a flange ring, two bases, and heat exchanger tubes that run through the housing and are each held in the bases at a longitudinal end side. A first flow channel may be formed in the heat exchanger tubes, and a second flow channel may be formed between the heat exchanger tubes and the housing. The housing may be formed from two one-piece and pot-shaped housing parts. Each housing part may have a housing section, a flange ring section, and a base. The two housing parts may be connectable to one another via the two flange ring sections.

Heat exchanger with housing parts connected by flange ring connection

A heat exchanger may include a tubular housing, a flange ring, two bases, and heat exchanger tubes running through the housing and respectively held at a longitudinal end side in the bases, a first flow channel formed therein, and a second flow channel formed between the tubes and the housing. The housing may be formed from first and second housing parts each being pot-shaped and having a housing portion, an outwardly widened flange ring portion, and a base. The housing parts may be connected to one another via the flange ring portions that may delimit an annular space. On the first housing part, inlet and outlet connecting-pieces for coolant may be provided. Between the housing and the heat exchanger tubes, at least one separator may be arranged, on which at least one blade may be provided, the blade engaging at least partly into the annular space and at least reducing a circumferential flow therein.

Heat exchanger with a separator

A heat exchanger is provided that includes a housing and an exchanger region which is arranged in the housing and has tubes and at least one base, wherein the tubes are connected to the at least one base, wherein the housing is manufactured from a plastic and has a housing inner surface, wherein the housing inner surface is covered at least in regions or in sections by at least one metallic element for protecting the housing from a thermal load. The invention further relates to a method for producing a heat exchanger.
