HEAT EXCHANGER

摘要

PURPOSE: A heat exchanger is provided to improve heat exchange efficiency by moving air passing through the surroundings of a pin to an area where louvers are formed. CONSTITUTION: A heat exchanger comprises header tanks, refrigerant tubes (200), pins (300), and louvers (400). The header tanks are separated from each other in a line. Both ends of the refrigerant tubes are fixed to the header tanks to form heat exchange medium paths. Protruded ribs (210) are formed on one end or both ends of the refrigerant tubes. The pins are fixed between the refrigerant tubes. Coupling grooves (320) corresponding to the protruded ribs are formed in the pins, and the protruded ribs are coupled thereto. The louvers are formed on the surfaces of the pins.
