Abstract: |
A fin heat exchange of gas ¨C liquid recuperative tube type with pin rib is featured as setting cylindrical or prismatic pin rib at gas side of said heat exchanger to replace flat board fin , dislocated fin and louver fin , welding two ends of pin rib on outer wall of liquid tube to let it be vertical to wall surface axially and to let it be arranged cyclically along liquid flow direction , arranging pin rib in each cycle with two modes of sequential arrangement and dislocated arrangement as several pieces of pin rib being set as a group being set in dislocated arrangement to each other , using 0.1 ¨C 0.25 mm as diameter of cylindrical pin rib and 0.1 ¨C 0.25 mm as sectional edge length of prismatic pin rib . |
