The invention relates to a spiral heat exchanger including a spiral body formed by at least one spiral sheet wound to form a first spiral-shaped flow channel for a first medium, and a second spiral-shaped flow channel for a second medium. The spiral body is enclosed by a substantially cylindrical shell with connecting elements communicating with the first flow channel and the second flow channel. The shell includes at least two shell parts, and the spiral body is provided with at least one fixedly attached flange on its outer peripheral surface, whereupon the at least two shell parts are removably attached.

The invention relates to a spiral heat exchanger including a central cylinder () and at least two spiral sheets (). The sheets extend from the cylinder to form a first spiral-shaped flow channel () for a first medium and a second spiral-shaped flow channel () for a second medium. The cylinder forms an inner space within the cylinder. The cylinder includes a first opening () communicating with the first flow channel and a second opening () communicating with the second flow channel. A pipe () extends into the inner space of the cylinder. A first communication channel, communicating with the first flow channel via the first opening, is formed within the pipe. A second communication channel, communicating with the second flow channel via the second opening, is formed in the inner space outside the pipe.
