Heat exchanger having enhanced performance

摘要

The invention relates to a heat exchanger including at least one elongate tube (3) adapted for the flow of a coolant, and at least one collection box (5) for such a coolant and into which one end of said tube leads, wherein the collection box includes a collector (9) having an element for receiving the end of said tube, the receiving element including a portion (19) projecting inwardly and shaped into an area for supporting said tube. According to the invention, the receiving element further includes a connection portion (21) for the inwardly projecting portion opposite the collector, and said connection portion protrudes on the side of the collector opposite the collection box such that said inwardly projecting portion (19) and said connection portion (21) have mutually opposite projecting directions.

主权项

1. A heat exchanger comprising:
elongate tubes arranged in an arranging direction parallel to each other, adapted to the circulation of a coolant fluid; and at least one collecting box for the coolant fluid into which one end of each of said tubes leads, wherein the collecting box comprises:
a manifold that receives the one end of each of said tubes, wherein the manifold comprises:
inwardly protruding portions formed in a retention zone for the tube, each of the portions of the inwardly protruding portions protrude in an insertion direction of the tubes and is in contact with and retains one of the tubes, andconnecting portions that connect a first protruding portion of the protruding portions to a second protruding portion of the protruding portions of the manifold, wherein each of the connecting portions protrude in a direction opposite to the insertion direction of the tubes, so that the protruding portion and the connecting portion protrude in opposite directions, wherein each of the protruding portions comprises an orifice that is longer in a direction perpendicular to the arranging direction and the insertion direction than in the arranging direction, wherein the protruding portions have a smaller thickness than the connection portions, and wherein the inwardly protruding portions have a shorter length along the insertion direction of the tubes than a length of the connecting portions along the insertion direction of the tubes.
