Abstract Refrigerant cooling coils inserted within a passage of brine in a heat exchanger are so deformed into a shape of flat elliptical cylinder that long axis of ellipse is parallel to a condensing surface, and a side or two sides of a pair of flat faces formed by deformation machining are fitted within the passage, closely contacted with an inner wall of the passage of the brine, in order to increase the contact surface between the refrigerant cooling ellipse coils and the inner wall of the passage of brine in the vapor trap plate and in order to enhance boundary film convection heat transfer coefficient of the brine circulated in the passage of said heat exchanger so as to provide excellent heat transfer property and great vapor condensing capability.
