Abstract
A fin for a finned pack for heat exchangers, includes a plate in which a plurality of through holes is made for the positioning of tubes to convey a first heat exchange fluid, the plate having an edge as well as two main faces each to be contacted by a second heat exchange fluid in a crossing direction from an inlet portion to an outlet portion of the edge of the plate.
Claims17
A fin for a finned pack for heat exchangers, comprising:
- a plate in which a plurality of through holes is made for positioning of tubes adapted to convey a first heat exchange fluid;
- said plate having:
- an edge;
- two main faces each adapted to be contacted by a second heat exchange fluid in a crossing direction from an inlet portion to an outlet portion of said edge of said plate;
- and
- said holes being delimited by a respective inner delimiting wall of said plate including a first portion facing towards said inlet portion and a second portion facing towards said outlet portion,
- said fin comprising at least one confinement unit of said second heat exchange fluid arranged around a hole of said plurality of holes to obtain at least one partially surrounded hole,
- said at least one confinement unit comprising two baffles arranged one opposite the other with respect to each respective partially surrounded hole and surrounding and spaced from a respective section of said second portion of said delimiting wall of said partially surrounded hole, so as to confine, during use, on said plate a first flow zone of said second heat exchange fluid between each baffle or recess and a respective section of said second portion of said delimiting wall, wherein said baffles comprise a drawn portion of said plate,
- wherein said baffles have a first section, a second section as well as a reinforcement section which is extended at the face of the respective baffle facing away from the respective partially surrounded hole and is extended from an intermediate zone of said first section to the free end of said second section.
