Abstract

THE INVENTION PROVIDES A FIN-AND-TUBE HEAT EXCHANGER USING A RETURN BEND TUBE THAT ALLOWS FURTHER ENHANCEMENT OF THE EVAPORATIVE PERFORMANCE OF THE HEAT EXCHANGER. THE FIN-AND-TUBE HEAT EXCHANGER, WHERE A REFRIGERANT IS SUPPLIED INSIDE TUBING, HAS A HAIRPIN TUBE PORTION (22) WHERE A PLURALITY OF HAIRPIN TUBES ARE ARRANGED, A RETURN BEND TUBE PORTION (22) WHERE THERE ARE ARRANGED A PLURALITY OF RETURN BEND TUBES JOINED TO RESPECTIVE HAIRPIN TUBE ENDS OF THE HAIRPIN TUBE PORTION (23), AND A FIN PORTION (21) COMPRISING A PLURALITY OF FINS ARRANGED AT A PREDETERMINED SPACING ON THE OUTER SURFACE OF THE HAIRPIN TUBES. THE HEAT EXCHANGER COMPRISES FIRST GROOVES FORMED ON THE TUBE INNER SURFACE OF THE RETURN BEND TUBE. A FIRST GROOVE PITCH (PI) OF THE FIRST GROOVES (2) IN A CROSS SECTION PERPENDICULAR TO A TUBE AXIS, AND A SECOND GROOVE PITCH (P2) OF SPIRAL-SHAPED SECOND GROOVES (12) FORMED ON THE INNER SURFACE OF THE HAIRPIN TUBE IN A CROSS SECTION PERPENDICULAR TO A TUBE AXIS, SATISFY A GROOVE PITCH RATIO (PL/P2) OF 0.65 TO 2.2, WHILE A FIRST GROOVE CROSS-SECTIONAL AREA (S1) PER GROOVE OF THE FIRST GROOVES (2) IN A CROSS SECTION PERPENDICULAR TO THE TUBE AXIS, AND A SECOND GROOVE CROSS-SECTIONAL AREA (S2) PER GROOVE OF THE SECOND GROOVES (12) IN A CROSS SECTION PERPENDICULAR TO THE TUBE AXIS SATISFY A GROOVE CROSS-SECTIONAL AREA RATIO (S1/S2) OF 0.3 TO 3.6.
