A coiled heat exchanger and a method of making the coiled heat exchanger. The heat exchanger includes a pair of corrugated plates connected to one another such that the crests of their respective corrugations contact. Edges of the sheets that correspond to the faces of the cylindrical core formed from coiling the sheets are bent and connected such that a substantially continuous and flat wall is formed between the two sheets. Portions of the wall are alternately cut open, left intact, and flattened so as to form a pattern of three distinct angular sectors on the face of the core. These angular sectors respectively include cut-open sectors configured to pass a heat transfer fluid therethrough, platform sectors configured for the mounting of headers thereon, and flattened wall sectors creating gaps configured to pass a heat transfer fluid therethrough. The heat exchanger is formed in a continuous process, with the edges connected to form the wall along the entire length of the sheets forming the coil and periodic portions of the wall flattened along the length. The sheets are then coiled and fixedly connected between their coils at particular locations. Finally, wall portions are cut open in periodic angular intervals on the core face to form the openings. |
