とによって、熱交換が促進される効果を得ている。Hereinafter, the operation of the heat exchanger according to the present invention will be explained in the case where it is used as a condenser of a refrigerator. High-temperature refrigerant gas from the refrigerant inflow lower flows through a large number of refrigerant flow holes 11 provided in the outer heat transfer fins 4 in the outer cylinder 2, while water from the water flow port 6 flows through the inner heat transfer fins in the inner cylinder 1. Heat is exchanged through a large number of water flow holes 9 provided in the tube 3 using the inner and outer heat transfer fins 3 and 4 and the wall surface of the inner tube 1 as heat transfer surfaces, and the refrigerant is condensed and liquefied while the water is heated. The water will cool down and become warm. At this time, since the inner and outer heat transfer fins 3.4 are closely attached to the water and refrigerant flow paths, heat exchange is promoted by having a high density and wide heat transfer surface. It has been effective.
