Abstract
A heat exchanger of the fin type with a forced air flow, comprising: a thermal exchange tube (10) having a plurality of mutually parallel rectilinear portions (11); and a plurality of flat fins (20), which are parallel to the direction of the forced air flow, spaced apart from each other and provided with openings (21) for the passage of said rectilinear portions (11), a pair of air flow deflectors (30) being provided downstream at least part of said rectilinear portions (11), each flat fin (20) having, from one of the faces thereof and laterally to the openings (21), alignments of fin projections (22) associated with respective fin windows (23) for the passage of the deflected forced air flow.
Claims6
A heat exchanger of the fin type to be used with a forced air flow, comprising:
- a thermal exchange tube having a plurality of mutually parallel rectilinear portions;
- a plurality of flat fins which are parallel to the direction of the forced air flow, spaced apart from each other and provided with openings for the passage of said rectilinear portions, each flat fin having, from one of the faces thereof and laterally to the openings, alignments of fin projections associated with respective fin windows for the passage of the deflected forced air flow;
- at least one plurality of pairs of deflectors, at least one pair of deflectors on a face of a flat fin between the alignments of fin projections and downstream of a respective opening and projecting in a diverging arrangement relative to the central axis of a said rectilinear portion to laterally deflect and whirl the forced air flow, each deflector having a height which is slightly less than the distance between the flat fin to which it is affixed and an adjacent flat fin.
