HEAT EXCHANGER CAPABLE OF IMPROVING HEAT EXCHANGE EFFICIENCY BY FORMING A BURR IN A PIN OF A HEAT EXCHANGER AND INCREASING HEAT EXCHANGE AREAS

摘要

PURPOSE: A heat exchanger is provided to improve heat exchange efficiency by forming a radial slit in a pin of the heat exchanger for the turbulence of air passing between the pins.;CONSTITUTION: A heat exchanger comprises a tube, a pin (100), and a connection unit. The tube comprises a fluid path. The pin is connected to the tube in order to cross the tube and forms a heat exchange surface. The connection unit connects the tube. The pin comprises a radial slit (120) extending around the interval between three or more tube insertion units (110) which are adjacent to the pins. A length of one or more slits is different from the other one.;COPYRIGHT KIPO 2013
