Counter flow types of heat exchanger having through fin creating the edge effect heat transfer enhancement with heat conduction effect, or twist fins stirring turbulence heat transfer promotion are examined by experiments. Four different types of the heat exchanger (no inserted fin, inserted fin, twist fins and twist fins with partition plate) were discussed based on the obtained numerical and experimental results from the view point of (1)pressure loss, (2)heat exchanged quantities, (3) temperature efficiency, (4)number of heat transfer units (NTU) and (5)exergy. The inserted through fins/twist fins were cleared to play an important role in the upgrade (performance up) of the counter flow type of the heat exchanger.
