FINNED AND FLAT TUBE-TYPE HEAT EXCHANGER AND EVAPORATOR USING FINNED AND FLAT TUBE-TYPE HEAT EXCHANGER

摘要

PURPOSE: A finned and flat tube-type heat exchanger and an evaporator using the finned and flat tube-type heat exchanger are provided to improve the heat exchange efficiency, reduce the size and weight of the heat exchanger, and smoothly discharge condensate, and apply the heat exchanger to the evaporator of an air conditioner. CONSTITUTION: A finned and flat tube-type heat exchanger(10) comprises plural flat radiant fins(30) disposed at regular intervals; plural flat tubes(40) orthogonally joined with the flat radiant fins; and plural return tubes(45) installed at the ends of the flat tubes; and refrigerant inlets and outlets installed on a side of the flat tube. A supplied refrigerant flows through the return tubes in a zigzag shape.
