Abstract
A heat exchanger, such as a condenser or gas cooler, having a collecting tube which has a wall and which can be produced by deformation of a single metal strip, which collecting tube has, in its base, at least one row of openings in which heat exchanger tubes, each of which has two narrow and two wide sides, are fastened at their ends. The collecting tube can have at least two chambers, which adjoin one another approximately at a central longitudinal axis, and also a reinforcement, which is formed by the longitudinal edge strips of the metal strip.
Claims16
A heat exchanger comprising:
- a collecting tube having a wall and being produced by deformation of a single metal strip, the collecting tube having a base with at least one row of openings in which heat exchanger tubes, each of which has two narrow and two wide sides, are fastened at their ends, the collecting tube having at least two chambers, which adjoin one another approximately at a central longitudinal axis of the collecting tube;
- and
- a reinforcement, which is formed by longitudinal edge strips of the metal strip, between the heat exchanger tubes, arcuate portions of the edge strips engaging correspondingly contoured interior portions of the base of the collecting tube wall,
- wherein the reinforcement which, is formed from the longitudinal edge strips, extends at least over ⅓ of the surface area of the base.
A collecting tube comprising:
- a wall for a heat exchanger;
- having at least two chambers, which adjoin one another approximately at a central longitudinal axis;
- and
- a row of openings in a base, heat exchanger tubes being securable in the openings, each of the tubes having two narrow and two wide sides;
- wherein the collecting tube is produced by deformation of a single metal strip and has a reinforcement, which is formed by the longitudinal edge strips of the metal strip of the base, the longitudinal edge strips including arcuate portions nested in concave interior portions of the base of the heat exchanger wall;
- wherein the reinforcement extends at least over ⅓ of a surface area of the base.
A method for producing a collecting tube, the method comprising the acts of:
- providing a single metal strip which has two longitudinal edge strips;
- forming openings in the metal strip and cutouts which come to rest in a base of the collecting tube;
- and
- shaping the metal strip such that two chambers which adjoin one another approximately at a central longitudinal axis of the collecting tube are formed;
- rolling the two longitudinal edge strips inwardly such that arcuate portions of the rolled edge strips bear against an arcuately shaped portion of an inner side of the base to reinforce at least ⅓ of the surface area of the base.
