HEAT EXCHANGER

摘要

The present disclosure relates to a heat exchanger with a particular crimped joint configuration between the manifold and the main body of the heat exchanger. To achieve the joint, the manifold comprises cavities distributed close to its perimetral edge, i.e., the edge that is coupled to the main body. The main body has a stepped seat on which the manifold is supported. Around the seat, the main body has a segment externally surrounding the manifold, at least in a band adjacent to its perimetral edge. This perimetral band has slots defining strips located between the slot and the free edge such that the strips, which are plastically deformed towards the inside of the cavities of the shell, establish a joint with a very rigid and strong coupling force.

主权项

1. A heat exchanger comprising:
a main body in turn comprising a shell, wherein
the shell houses one or more heat exchange tubes for passage of a first fluid, particularly a gas to be cooled, where heat exchange tubes extend between two opposite ends of the shell;the shell comprising a space between an inner face of the shell and the heat exchange tubes for passage of a second fluid, particularly a coolant fluid; andwherein the main body, in at least one of the ends of the shell, comprises a baffle such that the heat exchange tubes are attached to the baffle through one of the ends thereof, and a manifold in fluid communication with an inside of the heat exchange tubes attached to the baffle, this manifold being attached to the main body,wherein:
the manifold comprises a perimetral edge and a plurality of cavities on its outer face distributed around the perimeter and spaced from the perimetral edge, the main body is prolonged in a segment externally surrounding the manifold at least by a band adjacent to its perimetral edge wherein the main body comprises a stepping such that there is arranged a seat of the perimetral edge of the manifold on the stepping; and the segment of the main body externally surrounding the manifold comprises, coinciding with two or more cavities of the manifold and in each of such cavities, a strip configured between the edge of the segment of the main body externally surrounding the manifold and a slot spaced from the edge such that by plastic deformation, the strip enters the cavity of the manifold such that the free edge of the strip established by the slot is supported on the surface of the cavity arranged closest to the perimetral edge of the manifold.
