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.
