<p>The invention relates to a heat exchanger, whereupon the heat exchanger comprises a pipe section for liquid circulation and fin parts that are attached to the outer surfaces of the pipe section in order to enlarge the heat-exchange surface. In order to make the heat transfer more efficient, the fin parts are divided into at least two zones (5, 6). The pipe sections (8, 9) of the fin zones can be connected to collecting pipes (16) and to distributor pipes (18), so that after the liquid has passed through one fin zone (5) it is arranged to be mixed at least in one collecting pipe (16) before it is supplied to the distributor pipe (18) of the next zone (6), or to the distributor pipes of the following zones.</p> |
